Bathroom Remodel Permit in Saratoga, CA (2026)

Research by DoINeedAPermit Research Team · Updated May 2026

The Short Answer

A full bathroom remodel in Saratoga requires a permit if you relocate any plumbing fixture, add electrical circuits, install a new exhaust fan duct, convert tub to shower, or move walls. Surface-only work — tile, vanity, or faucet replacement in place — does not need a permit.

Saratoga adopts the 2022 California Building Code (Title 24) with local amendments that are stricter than many Bay Area neighbors on waterproofing documentation and electrical GFCI/AFCI enforcement. Unlike some nearby towns that streamline bathroom permits over-the-counter, Saratoga Building Department requires full plan review for any fixture relocation or new exhaust duct, which typically takes 2-3 weeks (not same-day approval). The city's foothills and mountain areas fall into seismic zone 4, which adds bracing requirements for heavy fixtures like soaking tubs. Coastal Saratoga (near Los Altos Hills) has different frost and drainage considerations than the valley side. Most critically, Saratoga strictly enforces IRC R702.4.2 waterproofing assembly specifications — you must specify your shower membrane system (cement board + liquid barrier, or pre-fabricated waterproof panel) on your permit plan, not just 'waterproofing' — vague submittals get rejected. The city's permit portal allows online filing and tracking, though plan review is not fully digital (you may need to revise PDFs and resubmit). Permit fees run $250–$650 based on declared valuation; add $150–$300 if you need revisions after initial rejection (common on shower-pan and electrical-outlet details).

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

Stop-work orders in Saratoga carry fines of $500–$1,000 per day once Building & Safety inspectors identify unpermitted work, plus mandatory re-permitting at 2.5x the original permit fee.
Title insurance and refinance denials: lenders routinely pull permit histories; unpermitted bathroom work discovered during appraisal or sale can kill financing and drop property value $15,000–$40,000 depending on scope.
Homeowners insurance claims for water damage from unpermitted plumbing or electrical work may be denied if the policy holder did not disclose the remodel during underwriting.
County assessor reassessment after discovery can trigger property tax increases of $50–$200 annually, retroactive to the year work was completed.

Saratoga full bathroom remodel permits — the key details

Saratoga's Building Department requires a permit whenever you move a plumbing fixture (toilet, sink, tub/shower drain), install a new exhaust fan duct (even if replacing an existing fan in the same location with a new duct routing), add electrical circuits or outlets, or modify framing. The city adopts California Building Code Title 24, which incorporates the 2022 International Building Code by reference. IRC P2706 governs drainage fittings and trap sizing; if you're relocating a toilet or shower drain more than 5 feet horizontally, the trap arm length becomes critical — Saratoga inspectors will verify the slope (1/4 inch per foot minimum) and total length (6 feet maximum for a 3-inch vent stack, less for 2-inch). Most rejections stem from submittals that fail to show trap-arm geometry or drainage routing. If your new shower location sits far from the main vent stack, you may need a wet vent or secondary vent (increases cost $400–$800 for framing, pipe, and roof penetration). Pressure-balance or thermostatic mixing valves are now required on all new shower/tub installations per California Plumbing Code Section 422.1, a state-level mandate that supercedes IRC. Don't assume your old rough-in location still works — Saratoga's plan-review staff will flag missing valve details.

Electrical work in bathrooms triggers the strictest code path. All outlets within 6 feet of a sink, tub, or shower must be GFCI-protected per NEC 210.8(A) (incorporated into California code). If you're adding a dedicated exhaust fan circuit, it must have its own breaker, AFCI protection if on a 20-amp circuit (NEC 210.12), and be labeled. Saratoga inspectors expect to see exhaust-fan electrical specs on your plan (wattage, CFM, duct size, damper requirement). A common error: submitting an electrical plan that doesn't call out bathroom outlets separately or doesn't specify GFCI outlets vs. GFCI breakers. The city's electronic permit portal allows you to upload a one-line electrical diagram; if your diagram is fuzzy or incomplete, the plan reviewer will request revisions (adds 5-10 days). Ventilation exhaust must terminate outdoors per IRC M1505.2 — soffit termination is NOT allowed in California (ducting must exit roof or gable wall with a damper). If your exhaust duct runs more than 25 feet from the fan, Saratoga may require a booster fan (noted in the inspection). The city's seismic zone 4 status means any heavy fixture (soaking tub, tile shower enclosure) needs bracing; framing plans must show blocking and fastening details.

Waterproofing specifications are the second-most-common rejection point. IRC R702.4.2 requires a continuous, impermeable membrane behind all shower and tub walls. Saratoga's plan-review notes (available on the city website FAQ) explicitly state that submittals must name the waterproofing system: cement board + liquid membrane (e.g., Redgard, Hydroban), pre-fabricated waterproof shower panels (Schluter, Wedi, etc.), or tile backer board with tape and sealant are acceptable; fiberglass bathtub surrounds in new locations are acceptable if seams are sealed per manufacturer. Simply writing 'waterproof the shower' will get rejected — the reviewer needs the product name and installation method. If you're converting a bathtub to a shower (or vice versa), the waterproofing assembly changes; a tub location may only have a simple surround, but a shower requires full-height membrane per R702.4.2, which typically adds $400–$800 in materials and labor. Saratoga's coastal areas (higher humidity year-round) and mountain foothills (seasonal moisture) both see mold issues if waterproofing is marginal; inspectors are more critical of shortcuts. Plan-review timelines: initial review 2-3 weeks, resubmittal review 1-2 weeks. Once approved, rough plumbing and electrical inspections must occur before drywall is installed; final inspection happens after all finishes are in.

Owner-builder rules in California allow homeowners to pull permits for their own home without a license, but only for the work they personally perform. Saratoga follows Business & Professions Code Section 7044: plumbing and electrical must be performed by or under the supervision of a licensed contractor (journeyman plumber, electrician) or state-licensed apprentice. Many bathroom remodels involve at least some plumbing (toilet relocation, new vent duct) and electrical (GFCI outlets, exhaust fan circuit); you can typically handle finishes (tile, painting, vanity cabinet) yourself, but must hire licensed trades for the rough work. Some homeowners try to avoid permits by claiming they'll hire a contractor to do everything, then do it themselves after; Saratoga Building Department audits permit files and may require a licensed contractor to be listed on the permit. If you go this route and fail inspection, you'll be cited and forced to hire a contractor to remediate — far more expensive than doing it right the first time. Permit fees are calculated at 1.5-2% of declared valuation; a $25,000 remodel (realistic for fixture moves, new ductwork, quality tile) incurs a $375–$500 permit fee, plus plan-review fees if revisions are required.

Saratoga's permit timeline from submission to final approval typically spans 4-6 weeks: initial intake (1-2 days), plan review (2-3 weeks), resubmittal and re-review if needed (1-2 weeks), rough inspections once work is framed (1 week to schedule), and final inspection (1 week). Pre-1978 homes in Saratoga are subject to California lead-paint disclosure laws; if your home predates 1978, you must provide a lead-paint disclaimer to anyone purchasing or renting. The permit pull itself does not require lead abatement, but the inspection process will flag any disturbed lead paint, and you may be required to contain it during demolition. Saratoga's building department does not issue emergency or temporary permits for bathrooms; if you're racing a closing date, you'll need to start your permit 8-10 weeks in advance. The city's online portal (accessible via the Saratoga city website under 'Building & Safety' or 'Permits') allows you to check permit status, download inspection reports, and pay fees electronically. Paper submissions are still accepted at City Hall (14575 Fruitvale Avenue, Saratoga) but add 2-3 days for processing. No same-day or over-the-counter approvals are available for bathroom remodels; all require formal plan review.

Three Saratoga bathroom remodel (full) scenarios

Scenario A

In-place tile and vanity swap in a 1980s Saratoga ranch (no fixture moves, no electrical, no ductwork)

You're replacing 30-year-old ceramic tile, removing the old vanity, and installing a new one in the same footprint with the existing sink drain connection. You're also swapping out the toilet (same location) and the faucet. No walls move, no new ducts, no new circuits. This is surface-only work and does not trigger a permit under Saratoga code. You'll pull building permit for nothing; the work is cosmetic alteration of an existing bathroom. However, if the existing vanity has a hole in the wall for the P-trap that doesn't align with your new unit, you'll need to patch and re-route slightly — once you move the trap connection more than 12 inches, you've relocated a fixture and now need a permit (and plumber inspection). Similarly, if your new vanity requires a GFCI outlet in a location where none exists, adding that outlet requires a new circuit and an electrical permit. The key dividing line: if your new bathroom layout uses all existing supply and drain rough-ins without modification, and all existing electrical outlets (within 6 feet of sink) already have GFCI protection, you're exempt. Inspect the wall cavity behind the vanity before finalizing your design; if the existing drain stub is in an inconvenient spot, moving it costs $1,500–$3,000 in labor and materials, plus $250–$400 in permit fees — worth factoring into your budget. Tile and paint work: no permit needed. Faucet swap: no permit. Toilet swap: no permit. Vanity swap in-place: no permit. Total cost, no permit: $3,000–$8,000 depending on tile quality and vanity finish.

No permit required (cosmetic resurfacing) | New vanity fits existing rough-in | GFCI outlet already present | Total project cost $3,000–$8,000 | No permit fees

Scenario B

Moving toilet and pedestal sink to opposite wall, tub-to-shower conversion with new waterproofing (foothills home, 2-inch cast-iron main)

You're gutting a 1970s bathroom in a Saratoga foothills home (elevation ~800 feet, seismic zone 4). The toilet is relocating from the east wall to the west wall (about 8 feet); the sink is moving from a corner to the opposite wall; the existing bathtub is being removed and replaced with a walk-in shower (new waterproofing required per IRC R702.4.2). The home's main drain is 2-inch cast iron, and the existing toilet and sink both connect to a 2-inch vent stack. When you relocate the toilet, the new trap arm will be roughly 7 feet long (exceeds the 6-foot maximum for a 3-inch vent, marginal for 2-inch). Saratoga's plan-review team will likely require a secondary wet vent from the sink to the toilet, or a separate vent stack to the roof (adds $800–$1,200 in labor and framing). The tub-to-shower conversion triggers full waterproofing assembly documentation: you must specify cement board + liquid membrane (Hydroban or Redgard, ~$300–$500 in materials) or a pre-fabricated waterproof panel system (Schluter, Wedi, $600–$1,200 installed). No generic 'waterproof surround' language will pass review; Saratoga's plan-review notes explicitly require the product name and installation method on the permit submittal. Framing plan must show blocking for the shower curb and valve escutcheon per seismic bracing requirements. Permit path: submit a full plumbing plan showing trap-arm length, vent routing, new drain elevation, and waterproofing detail; include a structural note confirming seismic bracing; submit photos of the existing plumbing if possible. Expect initial plan review to take 2-3 weeks, and a resubmittal if your vent routing isn't clear. Once approved, rough plumbing inspection (framing open, before drywall), then framing inspection (bracing), then drywall inspection (optional, often waived if no wall moves), then final (all finishes, waterproofing membrane visible during drywall phase). Total permit fee: $400–$550 (based on ~$30,000 declared valuation). Plumbing: $3,000–$5,000 (two moves, vent work, new drain slope). Waterproofing and tile: $2,500–$4,000. Timeline: permit approval 4 weeks, construction 6-8 weeks. Total cost: $25,000–$35,000.

Scenario C

New exhaust fan with 15-foot duct run to roof, two additional GFCI outlets, existing fixtures in place (Saratoga town center, 1950s home)

Your 1950s Saratoga ranch has a small, poorly ventilated bathroom with no exhaust fan. You're installing a new 110-CFM exhaust fan with a 4-inch duct that runs 15 feet through the attic to a roof vent. You're also adding two new GFCI outlets on a dedicated 20-amp circuit (bathroom outlets currently have only one outlet, shared with other rooms — a code violation you're fixing). The toilet, sink, and tub stay in their original locations. This triggers a permit for the electrical (new circuit, GFCI protection, exhaust fan duct) even though plumbing doesn't move. Saratoga Building Department requires: electrical plan showing the new 20-amp circuit, all bathroom outlets labeled GFCI, exhaust fan specs (wattage, CFM, duct size), damper location, and roof termination detail. Many homeowners assume they can run a bathroom outlet off an existing kitchen circuit or laundry circuit — wrong; Saratoga inspectors will red-tag it. The exhaust duct length (15 feet) is within acceptable range, but Saratoga's review notes will verify damper type (gravity, motorized) and insulation (flex ducts in unconditioned attics should be insulated to avoid condensation). If your attic is an unconditioned space with temperature swings (common in foothills), the plan reviewer may require R-6 insulation on the duct to prevent condensation inside. Rough electrical inspection occurs before drywall/finishes (if any walls are opened for the outlet boxes). Final electrical inspection confirms all outlets are tested for ground-fault protection and labeled. Permit fee: $200–$300 (lower valuation, no plumbing). Electrical labor: $600–$1,200 (new circuit, boxes, ductwork). Fan and damper: $150–$300. Total cost: $2,000–$3,500. Timeline: permit approval 2-3 weeks, electrical work 3-5 days, inspections 1 week. This is one of the lower-cost bathroom permits in Saratoga but still mandatory.

Saratoga's waterproofing documentation trap (and how to avoid rejection)

Waterproofing is the single most-rejected item on Saratoga bathroom remodel permits. The code requirement (IRC R702.4.2) is straightforward: all wet areas in showers and tubs must have a continuous, impermeable membrane. But Saratoga's building department and its contractors have learned, through years of water damage claims and mold remediation costs, that vague waterproofing specs lead to failures. The city's plan-review checklist (posted on the Saratoga Building Department website under 'Bathroom Remodel Guidelines') explicitly requires you to name your waterproofing system on the permit plan. 'Waterproof the shower' or 'install waterproofing per code' will result in a rejection stamp. You must specify one of these paths: (1) cement board (e.g., HardieBacker, Durock) + liquid membrane (Hydroban, Redgard, Aqua Defense); (2) pre-fabricated waterproof panel system (Schluter, Wedi, ProPanel); (3) fiberglass surround (for tub conversion only, if seams are sealed per manufacturer spec). Each has cost and labor implications. Cement board + liquid is the cheapest, typically $300–$500 in materials for a standard bathroom, but requires careful installation (mesh tape at all joints, primer, two coats of liquid, curing time before tile). Pre-fab panels run $600–$1,200 installed and are faster (fewer joints, less curing), but limit your tile and layout options. Include a detail drawing showing the waterproofing membrane at the top, bottom, and corner (30-inch height minimum behind the shower head per plumbing code). If your shower is recessed or has a curb, the membrane must extend 6 inches above the curb. Saratoga inspectors will visually inspect the membrane before you tile and will request documentation (photos, product receipt, installation sheet) if there's any question. Common mistake: homeowners hire a contractor, assume the contractor is handling the waterproofing correctly, and don't check until the inspection fails and the tile has to come off (costly rework).

Waterproofing becomes even more critical in Saratoga's mountain areas (elevation 1,000+ feet) where humidity and seasonal moisture retention is higher than the valley. Coastal Saratoga (near Los Altos Hills) has lower humidity but deals with salt air corrosion; metal fixtures and fasteners in bathrooms require stainless-steel or coated hardware. The foothills experience temperature swings that can drive condensation into wall cavities; moisture barriers behind drywall (6-mil polyethylene or house wrap) are recommended but not required by code. If you're doing a full gut bathroom in the foothills, your contractor may recommend spray foam insulation on the exterior walls to manage condensation — this is not a permit requirement but is a best practice that Saratoga inspectors appreciate (no red flags if it's done right). Budget $800–$1,500 for professional waterproofing installation (cement board + liquid membrane, labor only) or $1,200–$2,000 for a pre-fab panel system installed by the manufacturer's certified installer. The permit itself does not verify waterproofing quality (that's the inspector's visual check), so hire a contractor with references and local Saratoga experience. Ask to see photos of their last five bathroom remodels; if they hedge or can't provide them, look elsewhere.

Electrical GFCI/AFCI maze in Saratoga bathrooms (and why plan reviewers care so much)

Saratoga's electrical plan-review team is particularly strict about Ground-Fault Circuit Interrupter (GFCI) protection and Arc-Fault Circuit Interrupter (AFCI) protection, partly because California Building Code Title 24 Section 210.8 mandates GFCI on all bathroom receptacles (a state-level requirement that exceeds the National Electrical Code), and partly because Saratoga has had insurance claims from bathroom electrical fires and shock incidents. When you submit an electrical plan for a bathroom remodel, the plan reviewer expects to see: (1) all receptacles within 6 feet of a sink, bathtub, or shower labeled as GFCI-protected; (2) specification of whether GFCI outlets or a GFCI breaker is protecting them; (3) all outlets on 20-amp circuits in bathrooms protected by AFCI (either an AFCI outlet or AFCI breaker). Most homeowners don't understand the difference: a GFCI outlet protects only that outlet and any downstream outlets on the same circuit; a GFCI breaker (installed at the panel) protects the entire circuit. A single GFCI breaker in the panel protecting a 20-amp bathroom circuit is cheaper and simpler than buying three GFCI outlets, but the breaker approach is 'all or nothing' — if there's any fault, the whole circuit trips. Many modern bathrooms use a hybrid approach: a GFCI breaker at the panel (for convenience), plus individual GFCI outlets as backup and for ease of testing. Saratoga's plan reviewer does not care which you choose, as long as it's documented. Vague specs like 'GFCI protect all outlets per code' without specifying breaker vs. outlet will trigger a request for revision. AFCI is trickier: AFCI breakers are required by code on all circuits that supply outlets in bedrooms and kitchens (NEC 210.12), but not technically required in bathrooms unless the circuit also serves a bedroom. However, many Saratoga contractors install AFCI in bathrooms anyway for future flexibility. If your electrical plan doesn't mention AFCI and the circuit happens to share a breaker with a bedroom outlet, the plan reviewer will flag it. The safest path: specify AFCI + GFCI combo breakers (cost ~$40–$80 each, vs. $8–$15 for a standard breaker), which do both jobs and eliminate confusion. Rough electrical inspection in Saratoga requires the electrician to test all outlets with a GFCI tester (the plan reviewer will see the test results logged). If any outlet fails, the inspector will order rework before the circuit can be energized.

Common resubmittal errors: (1) submitting a one-line electrical diagram that doesn't label bathroom outlets separately from other room outlets; (2) failing to show the exhaust fan circuit (even a small 110-CFM fan needs its own 120V circuit, 15 or 20 amp depending on wattage); (3) showing bathroom outlets on a shared kitchen or laundry circuit (code violation, will be rejected); (4) not specifying the exhaust fan's electrical specs (wattage, CFM, duct size, damper). To avoid rejection, include a detailed electrical riser or single-line diagram with bathroom circuits clearly labeled, a notation for each bathroom outlet stating 'GFCI protected' or 'GFCI breaker [location in panel],' a separate line for the exhaust fan circuit (e.g., '110-CFM exhaust fan, 120V, dedicated 15-amp circuit, GFCI breaker at Panel A, Breaker 12'), and call-outs for any AFCI protection. If your home is older (pre-1980s) and has aluminum wiring, note this on the plan; Saratoga requires GFCI protection on all aluminum-wired circuits to mitigate fire risk. Some neighborhoods in Saratoga also have flooding concerns (near creeks or storm drain overflow zones); if your bathroom is in a flood-risk area, the electrical inspector may require outlets to be elevated above the 100-year flood level or have flood-resistant receptacles (costs ~$50–$100 per outlet). Most residential bathrooms won't face this, but check your flood-zone map on the Saratoga Planning Department website before designing.

Common questions

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

No, replacing a toilet in the same location with no changes to the water supply or drain is a cosmetic repair and does not require a permit. You'll only need a permit if you move the toilet to a new location, which requires a new drain and possibly a new vent. If you're concerned about the existing rough-in, call Saratoga Building & Safety for a quick phone consultation.

What happens if I finish my bathroom remodel without getting a permit and then try to sell the house?

Saratoga County Assessor's office may discover unpermitted work during a refinance appraisal, property sale inspection, or routine audit. If discovered, you'll be required to pull a retroactive permit and pass inspection (hard after finishes are done), pay the original permit fee plus a 25-50% surcharge, and possibly face a code violation on the property record. Title insurance companies may exclude coverage for unpermitted work, and buyers may demand a price reduction of $15,000–$40,000. It's far cheaper to get the permit upfront.

How long does it take to get a bathroom remodel permit approved in Saratoga?

Initial plan review typically takes 2-3 weeks from the date you submit your complete permit application. If the reviewer finds issues (missing waterproofing specs, unclear vent routing, electrical circuit conflicts), you'll receive a request for revisions, which requires 1-2 weeks to resubmit and another 1-2 weeks for re-review. Total time from submission to approval is usually 4-6 weeks. Saratoga does not offer same-day or expedited reviews for bathroom permits.

Can I do the work myself, or do I need to hire a licensed contractor?

California law allows homeowners to pull permits for their own homes and perform cosmetic work (tile, painting, cabinet installation) themselves. However, all plumbing and electrical work must be performed by or under the direct supervision of a licensed plumber or electrician. If your bathroom remodel involves moving fixtures (plumbing) or adding circuits (electrical), you must hire licensed trades. Saratoga's permit process will require a licensed contractor's name and license number on the permit application. Owner-builder work is allowed only if you're the property owner and the work is on your primary residence.

What is a pressure-balanced shower valve, and why does Saratoga require it?

A pressure-balanced (or pressure-compensating) valve automatically adjusts the water temperature if the water pressure changes (e.g., if someone flushes a toilet and cold water supply pressure drops). Saratoga adopts California Plumbing Code Section 422.1, which mandates pressure-balanced or thermostatic mixing valves on all new shower and tub installations to prevent sudden temperature spikes and scalding. This is a state-level requirement (not unique to Saratoga, but Saratoga's plan reviewers will verify it on your submittals). Budget $150–$300 for a quality pressure-balanced valve; cheap valves may fail inspection.

Do I need to hire a designer or engineer for my bathroom remodel permit in Saratoga?

For a simple bathroom remodel (fixture moves, new fan, new outlets), you do not need to hire a designer or engineer. You can submit a reasonably detailed sketch showing plumbing rough-in locations, vent routing, electrical outlets, and waterproofing specs. However, if your home is in a seismic zone 4 area (foothills) and you're installing heavy fixtures (soaking tub, large tile shower), a structural note confirming bracing may be required; a structural engineer or experienced contractor can draft this. If your bathroom involves moving load-bearing walls or extensive framing changes, a structural engineer is necessary. Most Saratoga permits do not require formal architectural drawings, but sketches must be legible and dimensioned.

My exhaust fan duct is going to run 30 feet through my attic. Does Saratoga require a booster fan?

Saratoga's plan-review notes do not explicitly require a booster fan for runs over 25 feet, but many inspectors recommend one (as a best practice per IRC M1505.3). A 110-CFM fan running 30 feet of 4-inch flex duct with two elbows will lose significant performance by the time air reaches the roof vent. A booster fan (inline duct fan, ~$100–$200) reinstates airflow. Check with your plan reviewer during the permit phase; they may request a booster fan or accept manufacturer documentation showing the fan's performance at 30 feet. If you skip it and the final inspector notes poor airflow, you'll be ordered to install one retroactively.

What's the difference between a bathroom remodel permit and a house remodel permit in Saratoga?

Saratoga does not distinguish between a 'bathroom remodel permit' and a 'house remodel permit' — all work requiring permits falls under the residential remodel category. However, minor permits (surface tile, vanity swap in place, no electrical or plumbing changes) are sometimes issued over-the-counter without formal plan review if the work is clearly exempt. Full bathroom remodels involving fixture moves, new exhaust ducts, or electrical circuits always require formal plan review and inspections. Saratoga's permit fee is based on the declared project valuation (square footage of renovated space multiplied by estimated cost per square foot, typically $75–$200 depending on scope).

Do I have to pull separate permits for plumbing, electrical, and general work, or one bathroom permit?

Saratoga allows a single combined permit for bathroom remodels; you submit one application that covers plumbing, electrical, and general work. The plan reviewer examines all three trades' plans and coordinates inspections. This is simpler and cheaper than pulling three separate permits. Some larger cities separate trades into different permit types, but Saratoga bundles them. You'll pay one permit fee, and inspections will cover all trades (rough plumbing, rough electrical, framing if needed, final).

What if I discover mold or lead paint during demolition in my pre-1978 Saratoga home?

Lead paint is common in homes built before 1978 and is not inherently dangerous unless disturbed or ingested. During permit-required bathroom work, you must follow California lead-safe work practices: wet-method demolition (spray water to suppress dust), HEPA filtering, and containment. The building permit itself does not mandate lead abatement, but if the inspector sees improper lead dust control, the job will be stopped. Mold is a separate health concern; if you discover mold during demolition (typically in wall cavities or around old plumbing), stop work and hire a mold professional to assess. Remediation is not a permit requirement but may be necessary for insurance or health reasons. Both issues are serious enough to warrant professional advice; do not attempt DIY removal.
