Bathroom Remodel Permit in Morgan Hill, CA (2026)

Research by DoINeedAPermit Research Team · Updated May 2026

The Short Answer

A full bathroom remodel in Morgan Hill requires a building permit if you're relocating plumbing fixtures, adding electrical circuits, installing a new exhaust fan, converting a tub to a shower, or moving walls. Surface-only cosmetic work (tile, vanity swap in place, faucet replacement) does not require a permit.

Morgan Hill Building Department follows 2022 California Building Code (CBC), which incorporates the International Residential Code (IRC) with California amendments. Unlike some neighboring Bay Area jurisdictions that allow over-the-counter approval for minor bathroom work, Morgan Hill requires full plan review and wet-seal approval for any project involving fixture relocation or plumbing/electrical system changes. This means you cannot pull a bathroom remodel permit and start work the same day — expect 2-3 weeks of review time before first inspection. Morgan Hill's permitting database also flags any pre-1978 home for lead-paint disclosure and risk assessment, which adds 1-2 business days to intake. The city uses the state's online ePlan system, so you can submit documents remotely, but many homeowners still choose to walk plans in at City Hall (6800 Santa Cruz Avenue) for same-day questions. Permit fees run $300–$800 depending on valuation, plus plan-review time charges if your scope exceeds standard bathroom-fixture relocation. The key Morgan Hill quirk: the city's electrical contractor must pre-approve GFCI/AFCI locations before rough-in inspection, so get that sign-off in writing before your electrician frames.

What happens if you skip the permit (and you needed one)

Code violation notices issued by the city carry $300–$500 fines per violation, and the Building Department is aggressive about following up on unpermitted plumbing and electrical work in residential bathrooms.
Your homeowners insurance will deny claims related to unpermitted plumbing or electrical work; water damage from a faulty drain or electrical fire from unpermitted circuits is your cost to absorb (typically $15,000–$50,000).
When you sell the home, you must disclose unpermitted work on the TDS (Transfer Disclosure Statement); buyers can demand a credit, require a retroactive permit with inspection, or walk away entirely — this has cost sellers $10,000–$40,000 in price reductions.
Refinancing your home is blocked until unpermitted bathroom work is disclosed to the lender; banks will not fund a loan against a property with known code violations, forcing you to pull a retroactive permit (extra fees, fines, and reinspection costs running $1,500–$5,000).

Morgan Hill full bathroom remodel permits — the key details

Morgan Hill Building Department enforces California Title 24 (energy), CBC Chapter 42 (plumbing), and CBC Chapter 27 (electrical) for all bathroom remodels. The core rule: any work that changes the plumbing system, electrical system, or structural envelope requires a building permit. This includes moving a toilet, tub, or sink; adding a new circuit or changing outlet locations; installing a new exhaust fan or duct; converting a bathtub to a walk-in shower; or removing/relocating walls. If you're only replacing a fixture in the same location (swap out a toilet for a new one without moving the drain, or replace a vanity with an identical footprint), no permit is required — that's considered maintenance. But most full bathroom remodels touch at least one of those systems, so a permit is almost always necessary. Morgan Hill's permit intake process requires a completed Application for Building Permit (Form 221), a plot plan showing the bathroom location on the house footprint, floor plans with all fixture locations and dimensions, electrical plans showing new circuits and GFCI/AFCI protection, plumbing plans showing drain lines and slope (minimum 1/4 inch per foot per CBC P2706), and a waterproofing assembly detail if you're building a shower. The waterproofing detail is non-negotiable: you must specify either a pre-fabricated shower pan with membrane liner or a mud-bed assembly with cement board and liquid-applied or sheet membrane. Generic drawings marked 'standard shower construction' get rejected. Plan review takes 10-15 business days; if there are markups (common issues include undersized drains, GFCI conflicts, or vague waterproofing specs), expect 3-5 more days per resubmission cycle.

Electrical work in a Morgan Hill bathroom is subject to NEC Articles 210 and 680 (adopted by CBC), with California amendments. The rule you can't skip: all receptacles within 6 feet of a sink, bathtub, or shower must be protected by GFCI (ground-fault circuit interrupter), and if the bathroom is wired as a branch circuit shared with other rooms, that circuit must also have AFCI (arc-fault circuit interrupter) protection. Many homeowners think GFCI is a receptacle type you buy at the hardware store and plug in — it is, but the Building Department requires that the GFCIs protecting the bathroom be either 1) integral outlets at the source (what an electrician calls a 'GFCI-protected outlet') or 2) a GFCI breaker at the panel (which protects the entire circuit). Your electrical plan must show this protection method; the inspector will verify it during rough-in. A common rejection: submitting a plan that shows standard receptacles and says 'GFCI outlets to be installed' — that's too vague. Specify which outlets, and have your electrician sign off that the protection meets NEC 210.8(A)(1). If you're adding a hardwired exhaust fan (common in full remodels to handle moisture), that circuit must be on a separate 20-amp branch or shared only with other bathroom circuits — sharing the bathroom branch with a hallway outlet is not allowed. Your electrical contractor must also verify that any new lighting, heat lamps, or ventilation fans you're adding don't exceed the home's panel capacity. In older Morgan Hill homes (built before 1990), this is often a limiting factor; you may need to upgrade the main panel from 100 amps to 150 or 200 amps, which adds $2,000–$4,000 to the project and requires a separate electrical permit and inspection.

Plumbing code in Morgan Hill bathrooms is governed by CBC Chapter 42, which references the International Plumbing Code (IPC). The centerpiece rule: any drain line from a toilet, tub, or sink must have a P-trap (U-shaped pipe that holds water to block sewer gas), a vent stack that rises above the roof, and proper slope. The slope matters: the line must drop at least 1/4 inch per foot (per IPC P2706) but no more than 1/2 inch per foot, or the water will drain too fast and leave solids behind. When you relocate a toilet drain, the new location must be within reach of an existing soil stack (the main vertical vent), or you're adding a new stack, which is a structural change and a more complex permit review. A second-floor bathroom draining to a first-floor rough-in can work, but the trap arm (the horizontal section between the trap and the vent) cannot exceed 42 inches — this trips up a lot of DIYers and contractors who eyeball the layout. Your plumber must calculate the trap arm length and show it on the plan. Similarly, if you're relocating a sink and connecting to a new drain line, the vent must be sized for the fixture's drain diameter; a 1.5-inch sink drain requires a 1.25-inch vent minimum per IPC P3106. Morgan Hill inspectors are strict about this because undersized vents lead to slow drains and callbacks. The other common plumbing issue: tub/shower rough-in. If you're converting a tub to a shower or installing a new tub-shower combo, the rough-in (the valve, trim, and drain assembly) must be for a pressure-balancing valve per IPC P2707.2 (adopted by California) — this prevents scalding if someone uses hot water elsewhere in the house. Your rough-in specification must say 'pressure-balanced diverter valve' or 'thermostatic mixing valve', not just 'shower valve.' Lead-paint is a separate issue: if your home was built before 1978, any bathroom work that disturbs paint, drywall, or plaster triggers California's Lead-Hazard Control Regulations (Health & Safety Code § 105680). Your contractor must be certified for lead-safe work practices or engage a lead-licensed inspector; the permit application will ask for this, and the city will add a lead-hazard notification document to your file. It's not a deal-breaker, but it means extra insurance and bonding requirements for the contractor.

Waterproofing and moisture control in a Morgan Hill bathroom must meet IRC R702.4.2 (shower surround waterproofing), which California has updated to require a complete shower enclosure system, not just tile. The two most common approved systems are 1) a prefabricated acrylic or fiberglass shower pan with an integrated drain, lined with a vinyl or rubber membrane, then walls finished with cement board and liquid-applied waterproof membrane topped with tile; or 2) a mud-bed (mortar-based) pan with a rubber membrane pan liner and drain, same wall assembly. The key point: your shower plan must specify which system you're using, the membrane type (elastomeric liquid, sheet membrane, or molded liner), and the substrate (cement board, cement backer board, or waterproof drywall). Vague specs like 'waterproof shower construction per code' get marked up and sent back. Morgan Hill inspectors will also verify that the membrane extends up the walls at least 6 inches above the tub rim or 6 feet above a floor-drain shower (per IRC P2706), and that the drain is sloped to the pan at a minimum 1/4 inch per foot. A common mistake: using regular drywall behind tile in a wet area — not allowed. The Building Department will require cement board or equivalent. If you're installing a steam shower or whirlpool tub, additional ventilation and structural support are required, and the plan review takes longer (3-4 weeks instead of 2). The building department also checks that your exhaust fan is sized correctly: minimum 50 CFM (cubic feet per minute) for a bathroom under 100 square feet, per IRC M1505.2. Many homeowners buy a 50 CFM fan for a 200-square-foot master bath and wonder why mold grows — you need at least 1 CFM per square foot of bathroom. The exhaust duct must terminate outside (not into an attic) and cannot tie into a dryer vent or an HVAC return. Your plan must show the duct routing, termination location, and damper type (gravity or powered).

Timeline and inspection sequence for a Morgan Hill full bathroom remodel runs roughly as follows: submit permit application and plans to the Building Department (online via ePlan or in-person at City Hall), allow 10-15 business days for plan review, receive approval or markups, resubmit if needed (2-5 more days per cycle), then receive permit (fee due at issuance). Once you have the permit, you can start demolition and framing. The first inspection ('rough plumbing') occurs after drains are in place but before walls are closed; inspector verifies trap arm length, vent sizing, slope, and that all fixtures are at the correct height. The second inspection ('rough electrical') happens after all new circuits, outlets, and GFCI/AFCI devices are installed but before drywall; inspector checks circuit sizing, GFCI protection, breaker labeling, and any new hardwired devices. A third 'framing' or 'drywall' inspection may occur if walls are being moved or if structural changes are involved; if you're only remodeling the bathroom interior and not touching framing, this might be skipped. The final inspection occurs after all finishes are complete — tile, paint, fixtures installed, exhaust fan ducted and operational, and electrical trim-out done. From permit approval to final inspection typically takes 4-6 weeks, depending on contractor pacing and inspector availability. Morgan Hill Building Department inspections are usually scheduled Monday-Friday, 8 AM - 3 PM; you must call ahead to schedule (phone number available on the city website). Inspection fees are included in the building permit fee; there are no additional per-inspection charges. If an inspection fails (common reasons: GFCI wiring incorrect, trap arm too long, membrane not extending to spec), you must correct and request re-inspection, typically within 7 days. Re-inspections add 1-2 weeks to the timeline.

Three Morgan Hill bathroom remodel (full) scenarios

Scenario A

Master bath tub-to-shower conversion, in-place fixture swap, hillside home (Morgan Hill foothills, 2,100 ft elevation)

You're removing a 5-foot bathtub and drainpan, relocating the drain roughing 18 inches to the left (to accommodate a new zero-threshold shower pan), and installing a new waterproofed shower enclosure with a 48-inch acrylic pan and sliding glass door. The existing valve is being replaced with a pressure-balanced diverter, and you're adding a new exhaust fan duct that runs through the attic to a roof termination on the north slope. The home was built in 1998, so lead paint is not an issue. This is a clear permit-required project because you're: 1) relocating the drain (must verify new location is within the soil-stack reach and trap arm stays under 42 inches), 2) installing a new waterproofed shower assembly (requires waterproofing detail and drain specifications), 3) adding a new exhaust fan circuit (requires GFCI breaker and damper spec on electrical plan). Your plumber must submit a drainage plan showing the new drain location, slope, trap arm length, and vent routing; your electrician must show the new 20-amp circuit, GFCI protection, and duct damper wiring. Plan review at the Morgan Hill Building Department typically takes 12-14 business days for a straightforward tub-to-shower. Expect one round of markups asking for the specific waterproof membrane type (liquid elastomeric or sheet) and confirmation that the trap arm is under 42 inches. Once approved, rough plumbing inspection happens after the pan and drain are set (before walls are closed) — the inspector will measure the slope and trap arm length and verify the pan is sloped correctly toward the drain. Rough electrical inspection follows, confirming the new circuit and GFCI breaker are labeled and the damper is wired (if motorized). The final inspection is the critical one: the inspector will verify that the membrane extends 6 feet up the walls (or 6 inches above the pan rim if it's a shower enclosure), the tiles are set over the membrane, the caulking is done, the exhaust fan is operational, and all fixtures are functioning. Total permit fee for this project is $450–$600, depending on the valuation Morgan Hill assigns. If you frame your own shower (budget DIY framing), expect $8,000–$15,000 total for the demo, pan, waterproofing, tile, fixtures, and permit fees combined. If you hire a general contractor, add 15-20% markup, so $10,000–$18,000. The foothills location (high elevation) is not a factor here because this is interior work, not grading or foundation, so no frost-depth or soil-expansion issues. Timeline from application to final inspection is typically 5-7 weeks, with most of the delay being plan review and waiting for inspection appointments.

Scenario B

Guest bathroom: vanity swap (same location), new recessed lighting, no plumbing changes, mid-peninsula flat (Morgan Hill valley, SFR zoned)

You're demolishing an existing 24-inch bathroom vanity, removing the old faucet, and installing a new 30-inch vanity with a new faucet in the exact same location. The drain line and supply lines do not move. You're also adding two new recessed light fixtures in the ceiling (both hardwired to an existing light switch circuit, no new circuit), and you're replacing the existing exhaust fan with a new, similar model in the same ductwork. The home was built in 2003. This is a no-permit scenario because: 1) the vanity is in-place (drain, supply, and trap are not relocated), 2) the faucet swap is fixture replacement (not a system change), 3) the new recessed lights are hardwired to an existing circuit (not a new circuit addition), 4) the exhaust fan is a like-for-like replacement (same ductwork, same amperage). California Building Code and Morgan Hill code both exempt fixture replacement and minor electrical additions to existing circuits. The key is that no new electrical circuit is being created — you're tapping into an existing light switch circuit, which is allowed for lighting under NEC 210.12 without additional GFCI or AFCI concerns. However, you should verify with the Building Department's intake staff that your electrician is not creating a new circuit; if the new recessed lights require more than 20% of an existing circuit's capacity, you might need a new dedicated circuit, which would trigger a permit. Best practice: call Morgan Hill Building Department before you start, describe the scope, and ask if a permit is needed. They typically say no for this scenario, but getting it in writing protects you. You can do this work without filing anything, and no inspections are required. Labor and materials for this job run $2,000–$4,000 (vanity, faucet, fixtures, electrician labor), and you avoid $400+ in permit fees. However, if you later sell the house, you should be able to document that this was routine maintenance (not a code violation), so keep your receipts and the vanity invoice. The exception: if your home has aluminum wiring (common in Morgan Hill pre-1975 homes), adding any new outlets or lights requires a licensed electrician and sometimes a re-rating inspection due to fire-code concerns. Check your panel to see if the main feeders or branch circuits are aluminum; if so, do not DIY this work — hire a licensed electrician and ask about whether a permit is needed (likely yes, due to special handling). For a typical post-1980 home with copper wiring, this is a straightforward no-permit job.

Scenario C

Master bathroom expansion: new wall, relocated toilet and sink, new 30-amp circuit for heated towel rack, 1976 home (Morgan Hill valley, possible lead paint)

You're gutting a 60-square-foot bathroom and expanding it into an adjoining storage closet (adding 40 square feet), which requires framing a new interior wall, relocating the toilet 8 feet east to the new layout, relocating the sink 5 feet north, adding a new 30-amp dedicated circuit for a hardwired heated towel rack, and converting a corner tub to a large walk-in shower. The home was built in 1976, triggering lead-hazard requirements. This is a complex multi-permit scenario: building permit (for framing and structural changes), plumbing permit (for drain/vent relocation), electrical permit (for new 30-amp circuit). Morgan Hill typically combines these into a single building permit with separate plan sheets. Your architect or designer must provide 1) framing plans showing the new wall location, headers, and structural support (if any bearing walls are involved); 2) floor plans showing the new toilet and sink locations with centerline dimensions and clearances (toilet needs 30 inches minimum from centerline to any wall or fixture per IPC P2705.1); 3) plumbing plans showing the new drain lines, trap arms, vent routing, and slope verification (both the toilet and sink drains must reach the soil stack, which likely requires either extending the existing stack or adding a new secondary stack — this is the critical complexity); 4) electrical plans showing the new 30-amp circuit, breaker labeling, and the heated towel rack wiring and outlet location (hardwired devices on dedicated circuits are required by NEC for many high-draw appliances); 5) waterproofing details for the new shower (liquid-applied or sheet membrane, height of coverage, drain slope); and 6) a Lead-Hazard Notification form (California HSC § 105680) because disturbance of pre-1978 paint/drywall triggers lead-safe work practice requirements. The Lead Certification adds 1-2 business days to the intake and requires your contractor to be California-certified for lead-safe practices or to engage a third-party lead inspector. Plan review for this complex project takes 3-4 weeks because the Building Department must verify the framing (does the new wall affect the home's structural integrity?), the plumbing (are the new drain lines feasible?), and the electrical (is the panel capacity sufficient for a new 30-amp circuit?). Expect 1-2 rounds of markups, commonly asking for: clarification of vent routing (how is the secondary vent connected to the primary stack or roof?), verification that trap arm lengths are under 42 inches, confirmation of the membrane system for the shower, and electrical calculations showing panel available capacity. Once approved, the inspection sequence is: 1) Framing inspection (after new walls are framed but before drywall), 2) Rough Plumbing (after drains and vents are in place), 3) Rough Electrical (after new circuit and outlet are roughed), 4) Drywall/enclosure inspection (optional, depending on the city's checklist), 5) Final (all finishes, waterproofing, fixtures, and systems operational). If the panel is undersized (100 amps in a 1976 home is common), you'll also need a separate electrical service upgrade permit, adding $2,000–$4,000 and 2-3 weeks to the timeline. Permit fees for the building permit run $600–$900, plus a separate plumbing permit (if issued) for $150–$250, for a total permit cost of $750–$1,150. A professional general contractor will bid this project at $20,000–$35,000 (demolition, framing, plumbing relocation, electrical circuit, shower waterproofing, tiling, fixtures, permits). The lead-paint certification adds $500–$1,000 to contractor costs if the contractor is already certified; if not, you'll need to hire a separate lead-licensed specialist, adding another $1,500–$2,500. Total project budget: $23,000–$38,500, plus 8-12 weeks from permit approval to final inspection. The Morgan Hill foothills zone is not a factor for this interior remodel, but if the bathroom is on a lower floor and the soil is expansive clay (common in Morgan Hill valley areas), the grading and foundation should already be engineered; verify there are no flood or landslide overlay district concerns (check the city's hazard map before investing in this remodel, as some properties in the valley are flagged for flooding, which may affect your budget and timeline).

Full building permit required | Framing plan required (new wall, structural review) | Plumbing relocation (toilet 8 ft, sink 5 ft, new vent stack or secondary vent) | New 30-amp dedicated circuit for heated towel rack | Waterproofing detail for walk-in shower | Lead-Hazard Notification (pre-1978 home) | Lead-safe work practices contractor certification required | Trap arm ≤42 inches verification | Panel capacity analysis, possible service upgrade ($2,000–$4,000 additional) | Framing, rough plumbing, rough electrical, final inspections | $600–$900 building permit + $150–$250 plumbing permit | $23,000–$38,500 total project cost | 8-12 weeks timeline

Morgan Hill's plan-review process: why your bathroom remodel takes 3 weeks instead of 3 days

Morgan Hill Building Department uses the state-mandated ePlan online system, but the review workflow is sequential, not parallel. You submit your application and all plans to the ePlan portal (or in-person at City Hall, 6800 Santa Cruz Avenue), and a permit intake specialist logs the project. If any documents are missing (plot plan, floor plan, electrical details, plumbing plan, waterproofing spec), the intake staff sends a request for additional information, which resets the clock — you have 14 days to resubmit, or the application goes dormant. Assuming everything is submitted, the application is routed to the Building Official (or their delegate) for plan review. For a standard bathroom remodel (no structural changes), this review takes 10-15 business days. The Building Official checks for compliance with the 2022 CBC, specifically focusing on plumbing (trap arm length, vent sizing, slope), electrical (GFCI/AFCI protection, circuit sizing), and waterproofing (shower assembly detail). If everything is correct, you get an approval and can pick up the permit. If there are issues (missing details, code violations, conflicts), the Building Official issues 'markups' or 'corrections' and returns the plans to you. You then have 14 days to correct and resubmit; the review clock starts over, and you wait another 5-10 business days. This sequential process means even minor markups can add 2-3 weeks to your timeline. To minimize delays, many homeowners hire a permit expediter or plan-review consultant who specializes in Morgan Hill code — they know exactly what the Building Official expects and can front-load the corrects before submission. This typically costs $500–$1,000 but saves 1-2 submission cycles.

Morgan Hill also has a unique overlay district system that affects some neighborhoods. If your home is in the Morgan Hill Historic District (typically older homes near the downtown area), any visible exterior work (including vent terminations, electrical meter relocation, or roof penetrations for exhaust ducts) must also get Historic Architectural Review Committee (ARC) approval, which adds 2-3 weeks to the timeline. Asking during intake whether your address is in an overlay district is critical — the city website has a zoning map tool. If your home is in a mapped flood zone (parts of Morgan Hill valley are designated by FEMA's FIRM maps), the Building Department may require elevation certificates or floodproofing assessments before issuing a permit; this is typically not an issue for interior bathrooms, but it's worth checking.

A practical tip for Morgan Hill homeowners: call the Building Department directly at least once before submitting plans. Ask to speak with the plan-review staff (the Building Official's assistant or the chief building inspector), describe your bathroom project scope in detail, and ask what documents and level of detail they require. Many applicants over-prepare (submitting 30-page specs when the city only needs 2 pages), and others under-prepare. A 10-minute call can clarify expectations and prevent rejection cycles. The city also offers 'pre-submittal conferences' for larger projects; even though a bathroom remodel is not huge, you can request one and walk through your plans with staff before formal submission — most cities do this at no charge and it's a smart investment.

California Building Code § 105280 (lead hazard control) and Morgan Hill bathrooms in pre-1978 homes

If your Morgan Hill bathroom is in a home built before January 1, 1978, any work that disturbs paint, drywall, plaster, or sealant triggers California's Lead-Hazard Control Regulations (Health & Safety Code § 105280 et seq.). This includes bathroom remodels involving demolition, sanding, cutting, or removal of materials that may contain lead. The regulation requires that your contractor be California-certified as a 'Lead-Safe Work Practices Contractor' (license type C-54) or that you hire a separate Licensed Lead-Hazard Assessor to oversee the work. The city's Building Department will require evidence of this certification before issuing the permit. A common misunderstanding: lead certification is not the same as a general contractor license. A GC with a C-10 or C-54 general-building license is not automatically lead-certified; they must take a separate 8-hour training course, pass a state exam, and register with the Department of Toxic Substances Control (DTSC). The cost to a contractor to get lead-certified is roughly $500–$1,000 upfront, which they may pass to you if they're not already certified. If your contractor is not certified, you have two options: 1) hire a separate Licensed Lead-Hazard Assessor to observe and approve your contractor's work (cost: $1,500–$3,000), or 2) ask your contractor to get certified before work starts (cost and timeline delay: 2-4 weeks). Morgan Hill takes lead hazard seriously because the Coyote Valley area has industrial legacy sites with possible lead exposure, so the city does not waive or skip this requirement.

Lead-safe work practices mean containment, isolation, and proper cleanup. Your contractor must 1) seal off the bathroom work area with plastic sheeting and HEPA-filter negative-pressure units (to keep lead dust from spreading), 2) use lead-safe demolition techniques (wet-cutting, not dry-cutting, to minimize dust), 3) contain all debris in sealed bags, 4) perform clearance testing after work (a certified lead inspector uses a XRF analyzer to verify that surfaces have been properly cleaned to below the action level), and 5) properly dispose of lead-contaminated materials at a licensed facility (not curbside trash). The permit fee for a pre-1978 bathroom remodel is the same as for a post-1978 home ($500–$800), but the contractor labor and cleanup costs increase by 15-25% due to containment and certification overhead. On a $20,000 bathroom remodel in a 1975 home, expect an extra $3,000–$5,000 for lead-safe compliance. You cannot skip this — Morgan Hill inspectors will stop work immediately if they discover unpermitted lead hazard disturbance, and the city will issue a Health Department notice requiring re-containment and re-testing.

A practical note: if your home's lead test status is unknown (you've never had it tested), ask your real estate agent or title company to check the property disclosure records — California requires sellers to provide a lead-hazard report. If one exists, use it to determine whether your home has confirmed lead. If no test has been done and you're planning a significant bathroom remodel, consider hiring a Licensed Lead-Hazard Assessor (typically $300–$600) to do a pre-disturbance inspection and XRF scan; this clarifies whether lead is actually present and helps your contractor plan the containment scope. Many homes built in the 1970s-1980s have lead paint, but not all — it's worth confirming rather than over-specifying containment for a lead-free home.

Common questions

Do I need a permit to replace my bathroom vanity and faucet in the same location?

No. Replacing a vanity or faucet in the same location without relocating the drain, supply, or trap is considered fixture maintenance and does not require a permit. You can do this work yourself or hire a plumber without filing anything with Morgan Hill. However, if you are moving the vanity to a new location (even 1 foot), you need a permit because the drain line moves.

How long does a bathroom remodel permit take to get approved in Morgan Hill?

Plan review typically takes 10-15 business days for a standard bathroom project (tub-to-shower, fixture relocation, exhaust fan). If the Building Official issues markups (corrections needed), add 5-10 business days per resubmission cycle. Complex projects involving framing changes, multiple vent relocations, or lead-hazard concerns can stretch to 3-4 weeks. Once approved, you can pick up the permit and start work immediately.

What is the most common reason for permit rejection on a Morgan Hill bathroom remodel?

Insufficient waterproofing detail for a shower. The Building Department requires you to specify whether your shower uses a prefabricated pan or a mud-bed assembly, the membrane type (liquid elastomeric or sheet), and the height the membrane extends up the walls. Plans that say 'standard shower construction' or 'waterproof per code' are sent back for clarification. Similarly, trap arm length (must be under 42 inches) and GFCI/AFCI protection details are frequently flagged if not clearly shown on electrical plans.

Can I do my own plumbing and electrical work on a bathroom remodel in Morgan Hill?

Partially. California Building Code and the state Business & Professions Code allow owner-builders to do some work themselves, but plumbing and electrical work must be performed or directly supervised by a state-licensed contractor (Class A plumber, Class A electrician, or equivalent specialty license). You cannot legally do the plumbing or electrical rough-in yourself; you must hire a licensed tradesperson. Finish work (like painting or tile) can be owner-done.

What does the bathroom GFCI requirement mean, and how do I know if I have it?

GFCI (ground-fault circuit interrupter) is a safety device that cuts power to outlets within 6 feet of water (sinks, tubs, showers) if a ground fault is detected, preventing electrocution. In Morgan Hill bathrooms, all outlets within 6 feet of water must be GFCI-protected. You can tell if an outlet has GFCI by looking for 'TEST' and 'RESET' buttons on the face; if your bathroom outlets don't have these buttons, you likely don't have GFCI protection and need to add it. A licensed electrician can install a GFCI outlet or a GFCI breaker at the panel (which protects the entire circuit).

My home was built in 1972. Do I need lead-paint certification for my bathroom remodel?

Yes. Any home built before 1978 is presumed to contain lead paint, and any bathroom demolition or remodel that disturbs paint, drywall, or plaster triggers California's Lead-Hazard Control Regulations. Your contractor must be California-certified as a Lead-Safe Work Practices Contractor (C-54 license) or you must hire a Licensed Lead-Hazard Assessor. The city will not issue a permit without evidence of lead certification. If your contractor is not certified, they can get certified (1-2 weeks and $500–$1,000 cost) or you can hire a third-party assessor ($1,500–$3,000).

I'm converting my bathtub to a walk-in shower. What do I need to show on my permit plan?

You need a waterproofing assembly detail showing the entire shower enclosure system: 1) the pan type (prefab acrylic or mud-bed with rubber liner), 2) the drain size and slope (minimum 1/4 inch per foot), 3) the wall substrate (cement board, not regular drywall), 4) the membrane type and how high it extends (minimum 6 feet up the walls or 6 inches above the pan rim), 5) the valve type (pressure-balancing diverter valve per code), and 6) the finished surface (tile or other waterproof material over membrane). A vague description like 'tile shower per standard practice' will be rejected; the Building Department needs specific details to approve the waterproofing.

How much does a bathroom remodel permit cost in Morgan Hill?

Building permit fees in Morgan Hill are based on project valuation (the estimated construction cost). For a typical full bathroom remodel ($15,000–$25,000 value), expect a permit fee of $400–$700. The fee structure is roughly 1.5-2% of valuation for residential work. Plumbing work may have a separate small permit if the city issues one ($150–$250). You pay the permit fee when you pick up the permit and cannot start work until payment is received.

What inspections are required for a Morgan Hill bathroom remodel?

Standard inspections are: 1) Rough Plumbing (after drains and vents are in place, before walls close), 2) Rough Electrical (after new circuits and outlets are roughed), and 3) Final (after all finishes, fixtures, waterproofing, and mechanical systems are complete and operational). If you're moving walls or doing structural framing, a Framing inspection is also required. If you're not changing the structural envelope or framing (common in cosmetic remodels), the Framing inspection is waived. You must schedule each inspection by calling the Building Department at least 24 hours in advance; inspectors are available Monday-Friday, 8 AM-3 PM.

Can I start my bathroom remodel before I get the permit approval?

No. You must have the permit in hand (proof of approval and payment) before starting any work. Starting work before the permit is issued is a code violation and can result in stop-work orders, fines of $500–$2,000, and forced removal of unpermitted work. Inspectors are trained to look for unpermitted bathrooms during routine home inspections or neighbor complaints, so the risk is real. Always get the permit first.
