Bathroom Remodel Permit in Covina, CA (2026)

Research by DoINeedAPermit Research Team · Updated May 2026

The Short Answer

A full bathroom remodel in Covina requires a permit if you relocate any plumbing fixture, add electrical circuits, install a new exhaust fan, convert a tub to shower, or move walls. Surface-only work—tile, vanity, or faucet swap in place—is exempt.

Covina's Building Department enforces state Title 24 and the current California Building Code, but applies a notably stricter interpretation of fixture-relocation triggers than some neighboring San Gabriel Valley cities. Where some jurisdictions exempt 'like-for-like' toilet or vanity replacements if the rough-in remains untouched, Covina's plan review process (which runs through their online portal and involves a mandatory 7-10 day initial plan check before any in-person counter review) flags ANY plumbing-fixture move, even if only 2 feet, as requiring a full mechanical permit. Additionally, Covina's flood zone overlay (portions of the city sit in Federal Emergency Management Agency flood zones) may impose extra waterproofing or elevation requirements on bathroom work if your property is in a mapped flood plain—something to confirm before filing. The city's permit fee for bathroom remodels typically runs $250–$600 depending on declared valuation, and rough-plumbing and rough-electrical inspections are mandatory before drywall closure. If you're owner-building, you can pull the permit yourself (per California Business & Professions Code § 7044), but all electrical and plumbing work must be performed by a state-licensed contractor—DIY electrical or plumbing is not permitted, even for owner-builders.

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

Los Angeles County Code enforcement issues stop-work orders ($500–$1,500 initial citation) and requires you to pull a permit retroactively, which doubles all permit fees and triggers a full re-inspection of concealed work.
Insurance claim denial: if a water leak or electrical fault from unpermitted bathroom work damages the home or a neighbor's property, most homeowner policies exclude coverage for unpermitted work ($10,000–$50,000+ exposure).
Home sale disclosure: California Real Estate Transfer Disclosure Statement (TDS) requires you to disclose all unpermitted work; non-disclosure is fraud and can void the sale or trigger rescission claims from buyers.
Refinance blocking: lenders require a final electrical inspection sticker and plumbing-rough approval before they will close; unpermitted work halts refinance entirely.

Covina full bathroom remodels — the key details

The threshold for needing a permit in Covina is straightforward: any plumbing-fixture relocation, new electrical circuit, new exhaust fan, tub-to-shower conversion, or wall movement requires a mechanical permit. This includes moving a toilet 18 inches to the left, relocating a sink to a new wall, or converting a 5-foot tub alcove to a walk-in shower. The reason is California Title 24 and the California Building Code (CBC) require verification that drain slopes, trap-arm lengths, vent routing, electrical grounding, and waterproofing assemblies all meet code before work is concealed. Covina's Building Department treats 'fixture relocation' broadly: even if you're reusing the same fixture and connecting to an existing rough-in stub, the city's plan reviewers will require updated plumbing and electrical plans showing the new layout, valve types (pressure-balanced per CBC P2701.1 for showers), GFCI/AFCI circuit protection (per NEC 210.12 and 210.8), and exhaust-fan duct termination details (per CBC M1505.2—typically 4-inch duct, hard-piped to exterior, no longer than 25 linear feet with no more than 2 elbows).

A common stumbling block in Covina is the shower waterproofing assembly specification. If you are converting a tub to a shower, or gutting and rebuilding a shower, Covina's plan reviewers require you to specify the waterproofing system on the mechanical permit application. The California Building Code (CBC R702.4.2) permits three waterproofing methods: (1) mortar bed with slope-shower pan liner; (2) cement board plus a liquid-applied membrane; or (3) pre-manufactured waterproof shower base. Covina's plan check almost always rejects applications that don't explicitly call out which method you're using, including brand and application thickness. This matters because inspectors will verify the membrane or pan is installed before drywall and tile go on; if you haven't pre-specified it, the project gets delayed 1–2 weeks while you revise and resubmit. Pressure-balanced shower valves (or thermostatic mixing valves) are also required per code; single-handle or manual valves do not meet the current CBC.

Electrical work in a bathroom remodel in Covina must show GFCI protection for all receptacles and AFCI (Arc-Fault Circuit Interrupter) protection for the branch circuit serving the bathroom (NEC 210.12(B)). If you are adding a new circuit for a heated towel rack, ventilation fan, or dedicated lighting circuit, the permit application must include an electrical one-line diagram or simple circuit schedule showing circuit breaker ratings, wire gauges, and GFCI/AFCI device locations. Covina's electrical inspector will not sign off rough-in without seeing stickers on the devices themselves. Additionally, if the bathroom is more than 5 linear feet from the panel and you're pulling a new circuit, some inspectors will flag inadequate wire size or conduit routing; plan for a re-inspection if the rough-in is not done to the standard. New exhaust fans are common; if you are installing one, the duct must be solid (no flexible duct longer than 6 feet in a single run per CBS), and must terminate to the exterior with a damper—venting into an attic, soffit, or crawlspace is not permitted.

Covina's permit filing process is entirely online via the city's permit portal. You must submit a completed mechanical permit application (Form PLD-104 or equivalent), site plan showing property lines and project scope, existing and proposed floor plans (if moving walls), updated plumbing riser diagram (showing all drains, vents, and supply lines), electrical one-line or circuit schedule (for new circuits), and a detailed specification sheet for the shower waterproofing system (if applicable). The initial plan check takes 7–10 days; the city will either approve with no issues, issue 'corrections needed' (requiring resubmission), or issue a 'disapprove' if major code issues are found. Most bathroom remodels receive 2–3 rounds of plan review. Once approved, you will receive a permit card and can begin work. Inspections are required at rough plumbing, rough electrical, and final. If you are a licensed contractor, you can request all three inspections on the same day in some cases; if you are owner-building, inspections are typically scheduled one at a time and spaced 3–5 days apart to allow drywall and patching work.

If the home was built before 1978, a lead-paint inspection and disclosure are required before interior renovation work begins (California Health & Safety Code § 105180). Covina's Building Department will ask for a lead assessment or a certified lead-risk assessor's sign-off before issuing the permit. Additionally, if the bathroom is in a Federal Emergency Management Agency flood zone (check your property address on the Flood Insurance Rate Map), the work may trigger additional waterproofing or elevation requirements; the plan reviewer will flag this during initial review. Permit fees for a full bathroom remodel in Covina range from $250 to $600 depending on the declared project valuation; there is no flat-rate permit. The fee is calculated as a percentage of valuation (typically 1.5–2% up to a maximum) plus plan-check fees ($100–$200). If the project is approved, paid, and construction begins, the permit is valid for 180 days; if work is not substantially started within that window, the permit expires and must be renewed. Inspections must be completed within 2 years of the permit issue date.

Three Covina bathroom remodel (full) scenarios

Scenario A

Vanity and faucet swap in-place, new tile, existing fixtures stay in original rough-in locations—1970s ranch in central Covina

You are replacing an old 30-inch vanity with a new 36-inch vanity, swapping out the faucet and P-trap, retiling the walls, and replacing the toilet in its original location. The rough-in plumbing (2-inch drain, 1/2-inch hot and cold supplies) is already in the wall and does not move. This is a surface-only cosmetic remodel. Covina's Building Department does not require a permit for this work because no fixtures are being relocated, no new electrical circuits are being added, no walls are being moved, and no exhaust fans are being installed. You can purchase fixtures at a local supplier, hire a handyperson or do the work yourself, and proceed without filing. The only caveat: if the home was built before 1978, you will want to test for lead paint on the existing vanity backsplash and tile before disturbing it; a simple lead wipe test kit (cost $15–$30) from a hardware store will confirm whether lead abatement is necessary. Your total material cost will likely run $1,500–$3,500 (vanity $400–$1,200, faucet $150–$400, tile $500–$1,000, labor if hired $500–$1,000), and there are no permit fees. No inspections are required. However, if you later decide to relocate the toilet or vanity even 12 inches to improve layout, or to add a new exhaust fan duct, you will need to pull a permit retroactively before closing the walls.

No permit required (surface-only work) | Lead test recommended if pre-1978 ($15–$30) | Material cost $1,500–$3,500 | No permit fees | No inspections required

Scenario B

Tub-to-shower conversion with relocated plumbing—2-story 1990s home in east Covina, near flood zone

You are removing a 5-foot alcove tub and installing a 42-inch corner walk-in shower. The shower valve will be relocated 18 inches higher and 2 feet over from the original tub spout location. You are adding a 4-inch round exhaust fan with a duct running 15 feet horizontally through the attic to a soffit termination. The home is in a mapped Federal Emergency Management Agency flood zone (100-year floodplain, elevation 300 feet). This is a full-scope remodel requiring a mechanical permit. Here's what you must file: (1) a completed permit application declaring valuation at $8,000–$12,000 (bathroom remodels of this scope typically run $8k–$15k); (2) updated plumbing plan showing the new shower valve location, pressure-balanced valve spec, drain routing (2-inch PVC with 1/8-inch per-foot slope per CBC P2706), and vent stack connection (all drains must connect to a vent within 2.5 times the pipe diameter per CBC P2706.1); (3) electrical plan showing the 20-amp GFCI circuit for the exhaust fan and a 15-amp GFCI circuit for the shower lights; (4) a detailed specification sheet for the shower waterproofing system—in this case, Covia's plan reviewers prefer a cement-board base (such as Hardiebacker or USG Durock) with a liquid-applied membrane (such as Redguard or Schluter KERDI) as the assembly to meet CBC R702.4.2; and (5) a note that the shower base elevation meets or exceeds the 100-year floodplain elevation (Covina's floodplain administrator will flag this if the shower is being installed below the flood elevation, which would require a flood vent or elevation mitigation). The permit will cost roughly $350–$500 in fees ($300–$350 for the permit + $75–$150 plan-check fee). Plan review will take 7–10 days; expect 2 rounds of corrections (common issues: vent routing, shower waterproofing spec, exhaust-fan duct size or termination). Once approved, you will schedule a rough-plumbing inspection (vent stacks, drains, and supplies in place before drywall), rough-electrical inspection (GFCI/AFCI breakers and fan circuit wired, sticker on device), and final inspection (tiles, membrane, and paint complete). The exhaust fan duct termination will be inspected to confirm it terminates to exterior, has a damper, and does not vent into the attic (a common defect). Total timeline is 4–6 weeks from permit issue to final sign-off. Labor cost for a contractor to demo, replumb, and install the waterproofing system typically runs $4,500–$7,000; material for the shower base, membrane, fixtures, and tile adds $3,000–$5,000.

Scenario C

Full bathroom gut and rebuild with new electrical panel sub-feed and wall relocation—older 1960s Craftsman, owner-builder pulling permit

You are gutting the entire 8-foot-by-10-foot bathroom, moving the toilet 4 feet to the opposite wall, relocating the sink to a new 48-inch vanity along the entrance wall, removing a non-load-bearing stud wall to create an open layout before the toilet alcove, installing a walk-in shower (tub removed), and running a new 20-amp sub-feed from the main panel for a dedicated bathroom circuit (GFCI + AFCI). This is a comprehensive remodel with multiple triggering factors: fixture relocation, electrical work, wall removal, new vent routing, and tub-to-shower conversion. As an owner-builder in California (per B&P Code § 7044), you are permitted to pull the permit yourself, but all electrical and plumbing rough-in work must be performed by a state-licensed electrical contractor and a state-licensed plumbing contractor (you cannot perform these trades yourself even as the property owner). Mechanical and framing work (wall demolition, drywall, paint, tile) you may do yourself. The permit application will require: (1) a stamped structural engineer's letter confirming the stud-wall removal is non-load-bearing (cost $300–$500); (2) detailed existing and proposed floor plans showing the wall removal and new fixture locations; (3) a full plumbing riser diagram with all drains, vents, and supplies, including trap-arm lengths (max 3 feet per CBC P2706.4 unless it's a 4-inch stack, which allows up to 6 feet), vent routing (all new drains must tie into a vent within 2.5 pipe diameters); (4) electrical plan showing the new sub-feed from the main panel, breaker size, wire gauge, and GFCI/AFCI device locations on the bathroom circuit; (5) shower waterproofing specification (cement board + membrane or pre-fab pan); and (6) a lead-paint assessment (the home was built in 1966, so lead is likely present). The permit valuation for this scope is typically $15,000–$25,000 (full demolition + replumbing + new electrical + tile + fixtures). Permit and plan-check fees will total $400–$700. Plan review will take 10–14 days and likely 2–3 rounds of corrections (common issues: vent stack sizing, trap-arm length, wall removal structural letter, electrical sub-feed sizing, shower waterproofing spec). Once approved, inspections will be required at: framing (wall removal, new studs, blocking for grab bars), rough plumbing (vents, drains, supplies), rough electrical (sub-feed, breaker, GFCI/AFCI, exhaust fan circuit if applicable), and final (waterproofing membrane inspection before tile, final electrical sticker, final plumbing sign-off, final drywall and paint). Because you are owner-building, each inspection must be scheduled individually and you will need to be present; the city does not combine owner-builder inspections on the same day. Timeline is 6–10 weeks from permit issue to final. You will spend $3,000–$6,000 on plumbing contractor labor, $2,000–$4,000 on electrical contractor labor, and $5,000–$10,000 on materials (fixtures, tile, shower base, vent stack, drywall, paint), for a total project cost of $10,000–$20,000.

Permit required (fixture relocation + wall removal + electrical sub-feed) | Owner-builder OK but electrical/plumbing must be licensed contractor | Structural engineer letter required ($300–$500) | Valuation $15,000–$25,000 | Permit fee $400–$700 | 4 inspections: framing, rough plumbing, rough electrical, final | Timeline 6–10 weeks | Lead assessment required (pre-1978 home)

Covina's online permit portal and plan-review process

Covina's Building Department operates entirely through an online permit portal; there is no counter service for mechanical permits in the traditional sense. You must create an account, upload your application (mechanical permit form), site plan, floor plans, and specifications as PDF files, and pay the permit fee ($250–$600) online via credit card. The portal automatically routes your application to a plan reviewer, who has 7–10 business days to conduct an initial review. Unlike some San Gabriel Valley cities that accept marked-up redlines, Covina's system issues either 'No Corrections Needed' (rare on first submission), 'Corrections Needed' (you fix and resubmit), or 'Disapproved' (major code issues, project must be redesigned). This means you will typically go through 2–3 rounds of corrections before approval, adding 2–4 weeks to the timeline.

Common Covina plan-review defects for bathroom remodels include missing shower-waterproofing system specs, vent-routing diagrams that don't show the vent stack size or connection point, exhaust-fan duct sizes that exceed 6 inches or have more than 2 elbows, and electrical circuits lacking GFCI/AFCI notation. The city's plan reviewers are meticulous about citing the specific code section (e.g., 'CBC M1505.2 requires duct termination to exterior with damper; plans show soffit termination without damper notation'). When you receive corrections, you must resubmit revised PDFs through the portal within 14 days, or the permit application will expire and you must restart the process. There is no phone-in option for plan review; all communication is through the portal.

Once approved, the portal generates a permit card (PDF) that you print or show on your mobile device. You cannot begin work until the permit is paid and the approval letter is in hand. Inspections are scheduled via the portal as well; you submit a request, the city assigns a 2-hour inspection window, and an inspector from the Building Department visits your site. For owner-builders, inspections are sequential (not combined); you must schedule rough plumbing, wait 3–5 days for drywall, then schedule rough electrical, etc. This is slower than hiring a licensed general contractor, who can often get multiple inspections on the same day.

Waterproofing, GFCI/AFCI, and pressure-balanced valves—the three code hot-buttons in Covina bathroom remodels

Waterproofing is the most common plan-review rejection in Covina bathroom remodels. The California Building Code (CBC R702.4.2) allows three methods for tub and shower areas: (1) a mortar-bed slope-shower pan with a membrane liner (traditional but labor-intensive); (2) a cement-board base with a liquid-applied or sheet-applied waterproofing membrane; or (3) a pre-manufactured waterproof shower base (acrylic, fiberglass, or solid-surface). Covina's reviewers require you to specify which method BEFORE the permit is issued, including the brand and product name (e.g., 'Hardiebacker 500 cement board with Redguard liquid-applied membrane, per manufacturer spec'). The inspector will visit during rough-in to verify the correct product was installed and the membrane is continuous. If you have not pre-specified it on the permit, the city will reject your plan or issue a correction, delaying you 1–2 weeks. Many contractors in Covina use the cement-board-plus-liquid-membrane approach because it is fastest and most forgiving of minor installation errors; pre-manufactured bases are also popular for small walk-in showers.

Electrical GFCI and AFCI requirements are equally strict. Every bathroom receptacle within 6 feet of a sink, toilet, or tub must be protected by a GFCI (Ground Fault Circuit Interrupter); the entire bathroom circuit (lights, exhaust fan, heated-towel rack) must be on a 15- or 20-amp AFCI (Arc-Fault Circuit Interrupter) breaker per NEC 210.8 and 210.12(B). Covina's electrical inspector will not sign off rough-in unless GFCI and AFCI devices are physically present in the panel or as in-line devices, and stickers are affixed to each outlet. If your permit plans show receptacles without GFCI notation, the city will issue a correction. A common mistake is assuming a single GFCI outlet will protect downstream receptacles; while this is allowed, it often confuses inspectors, so it's clearer to show GFCI breaker protection on the panel.

Pressure-balanced shower valves (or thermostatic mixing valves) are required per CBC P2701.1 for any bathtub or shower installed in a residential building. These valves prevent sudden temperature swings if another fixture (e.g., a toilet flush) diverts cold water. Single-handle manual valves and basic two-handle cartridge valves do NOT meet code. Many homeowners and contractors overlook this, specifying a $200 basic faucet instead of a $400–$600 pressure-balanced valve. Covina's inspector will fail the final plumbing inspection if a non-compliant valve is installed. This detail must be called out on the mechanical permit—either in the fixture schedule or in a note on the plumbing plan—so the city's reviewer knows you understand the requirement.

Common questions

Do I need a permit to replace a toilet in the same location?

No, if you are removing an old toilet and installing a new one in the exact same rough-in location, this is a fixture replacement and does not require a permit. You can purchase a new toilet at a home-improvement store and install it yourself or hire a plumber. However, if you are relocating the toilet even 12 inches—e.g., moving it to the opposite wall—you will need a mechanical permit. The rough-in distance from the wall, drain-pipe routing, and vent connection all change, and Covina requires verification of the new layout.

Can I do the plumbing and electrical work myself if I am owner-building?

No. California Business & Professions Code § 7044 allows owner-builders to pull permits and perform work on their own property, but plumbing and electrical work are restricted to licensed contractors. You cannot perform any plumbing (rough-in, trim-out, fixture connections) or electrical work (panel modifications, circuit wiring, GFCI/AFCI installation) yourself. You must hire a state-licensed plumbing contractor and a state-licensed electrical contractor. You may perform framing, drywall, paint, and tile work yourself if you are the owner-builder.

How long does plan review take in Covina?

Initial plan review takes 7–10 business days. However, most bathroom remodels receive 2–3 rounds of corrections before approval (common issues: shower waterproofing spec, vent routing, GFCI/AFCI notation, exhaust-fan duct termination). Each round of corrections adds 7–10 days. Total plan-review time is typically 3–4 weeks from initial submission to approval. Once approved, inspections are scheduled on demand, with 2–3 days between each inspection to allow framing, drywall, or utility work.

What is the permit fee for a full bathroom remodel in Covina?

Permit fees in Covina are calculated as a percentage of project valuation (typically 1.5–2% up to a maximum) plus plan-check fees ($100–$200). For a typical full bathroom remodel valued at $10,000–$15,000, the total permit and plan-check fees will be $250–$450. If the remodel is more comprehensive (e.g., moving walls, new electrical sub-feed), valuation may be $15,000–$25,000, bringing permit fees to $400–$600. Fees are paid online at the time of permit application.

Do I need a lead-paint assessment before remodeling an older bathroom?

Yes, if the home was built before 1978. California Health & Safety Code § 105180 requires a lead-risk assessment before any interior renovation (which includes bathroom remodels). Covina's Building Department will ask for proof of a lead assessment or a letter from a certified lead-risk assessor before issuing the permit. The assessment typically costs $300–$500 and takes 1–2 weeks. If lead is found, you must hire a certified lead abatement contractor to safely remove or encapsulate it before renovation. If you proceed without an assessment, the permit will be denied.

What if my bathroom is in a flood zone?

Covina has mapped flood zones (100-year and 500-year floodplains) in several areas. If your property is in a mapped flood zone, the city's plan reviewer will flag it and may require that the bathroom (including fixtures, electrical outlets, and HVAC equipment) be elevated above the 100-year floodplain elevation, or that you install a flood vent or backflow preventer. This can add cost and complexity to the remodel. Check your property address on the Federal Emergency Management Agency Flood Insurance Rate Map (available at fema.gov) before designing your remodel. If flood-related modifications are required, your permit fee and timeline will increase.

Can I get a permit exemption if the bathroom remodel is small?

No. Covina does not grant exemptions for 'small' remodels if the work includes fixture relocation, new electrical circuits, or wall movement. However, if you are only replacing fixtures in place (toilet, vanity, faucet swap with no relocation), retiling, or updating paint, a permit is not required. The city's threshold is based on the TYPE of work, not the dollar amount. If you move anything, you need a permit.

What inspections are required for a bathroom remodel in Covina?

For a full bathroom remodel with fixture relocation and waterproofing changes, Covina requires: (1) rough plumbing (vent stacks, drains, supplies in place before walls are closed); (2) rough electrical (GFCI/AFCI breakers and circuits wired, device stickers applied); and (3) final (waterproofing membrane verified before tile, final electrical sticker, final plumbing sign-off, fixtures installed, paint and tile complete). If you are also moving walls, a framing inspection before drywall is required. Each inspection must be scheduled via the permit portal; inspectors will issue a pass or a correction list. If corrections are needed, you must fix the issues and request a re-inspection (additional fee: $50–$100 per re-inspection).

What happens if I need to change my scope of work after the permit is issued?

If you modify the scope (e.g., adding a second exhaust fan, relocating the sink when you had not planned to, or upgrading the shower waterproofing system), you must request a permit amendment via the online portal. The amendment is reviewed by a plan checker and may require revised drawings or specifications. Amendment fees are typically $75–$150. If the change is major (e.g., expanding valuation by more than 25%), the city may require a new permit rather than an amendment. It is better to design the entire scope carefully before submitting the initial permit to avoid amendments and delays.

How long is the permit valid, and what if I don't finish work on time?

A mechanical permit in Covina is valid for 180 days (6 months) from the issue date. Work must be substantially started within this window. If you have not started by day 180, the permit expires and you must pull a new one. Once work is started, you have 2 years to complete all inspections and obtain a final approval. If you are nearing the 180-day mark and have not started, you can request a permit extension (typically granted once, for an additional 180 days) via the permit portal, though fees may apply. Always plan your construction timeline before pulling the permit.
