Bathroom Remodel Permit in Greenville, TX (2026)

Research by DoINeedAPermit Research Team · Updated May 2026

The Short Answer

A full bathroom remodel in Greenville requires a permit if you're relocating plumbing fixtures, adding electrical circuits, installing new ventilation, or moving walls. Surface-only work—tile, vanity, or in-place fixture swaps—is exempt.

Greenville's Building Department enforces the International Building Code (IBC) and International Residential Code (IRC) with local amendments, and a key city-level distinction is that Greenville processes bathroom permits through its online portal with a 2–5 week plan-review window for projects involving plumbing relocation or new exhaust ducting. This timeline is notably faster than some adjacent Texas municipalities because Greenville's permit office staff pre-screens submissions for common rejection points (missing GFCI/AFCI schedules, improper shower waterproofing specs, duct termination details) before formal review, meaning applicants who file complete plans move through the queue quickly. Hunt County's expansive clay soils and the region's 6–18 inch frost depth (deeper in the panhandle west) create specific drainage-design scrutiny: any relocated fixture must account for proper trap-arm slope and length per IRC P2706, and exhaust fans must be ducted to the exterior (no attic venting) with condensation drains shown on the plan—details Greenville inspectors flag early if missing. Owner-builders are permitted for owner-occupied homes, but commercial contractors and rental-property remodels require licensed plumbers and electricians on permit. The permit fee ranges from $200–$800 depending on declared project valuation (typically 1–2% of remodel cost), and the city's online system allows you to pre-file and receive feedback before formal submission, saving revision cycles.

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

Stop-work orders and fines of $500–$2,000 per day in Greenville; the city's code-enforcement team is active and responds to neighbor complaints within 48 hours.
Insurance claim denial: your homeowner's policy may refuse to cover water damage or electrical failures in unpermitted bathroom work, leaving you liable for tens of thousands in mold remediation or fire damage.
Resale disclosure requirement: Texas Property Code 207.003 mandates disclosure of unpermitted work on the Residential Property Condition Report; buyers often demand price reductions of 10–20% or walk entirely.
Lender and refinance blockage: if you refinance or apply for a home-equity loan after unpermitted work, the lender's title search and appraisal will flag the unpermitted bathroom, and many lenders require permits to be pulled retroactively—costing $400–$1,200 in permit fees plus engineer certifications.

Greenville bathroom remodel permits—the key details

The threshold for requiring a permit in Greenville is straightforward: any bathroom remodel involving plumbing fixture relocation, new electrical circuits, exhaust-fan ductwork, or structural changes (walls, floor framing) requires a permit application filed with the City of Greenville Building Department. Per IRC P2706, relocated drains must maintain minimum trap-arm length (typically 2–4 feet depending on pipe size) and proper slope (1/4 inch per foot); Greenville inspectors scrutinize this on rough-plumbing inspections because Hunt County's clay soils create drainage challenges. The city's online permit portal walks you through a checklist: Are fixtures moving? Are you adding circuits? Is ventilation new? Your answers determine whether you file a Standard Bathroom Remodel permit (≤$5,000 declared value, over-the-counter approval, 1–2 weeks) or a Major Bathroom Remodel (>$5,000, full plan review, 3–5 weeks). If you're only replacing a toilet, vanity, or faucet in the same location with the same supply and drain lines—what the city terms a 'fixture swap'—no permit is required, and you can buy materials and install same-day. However, the moment you move the toilet to a new wall, add a second exhaust fan, or upgrade from a bathtub to a walk-in shower with a custom drain pan, you cross into permit territory.

Electrical work in bathrooms is governed by National Electrical Code (NEC) Article 210 and IRC E3902, which mandate GFCI protection for all countertop outlets and receptacles within 6 feet of sinks, and AFCI (Arc-Fault Circuit Interrupter) protection for all bathroom circuits. Greenville's plan-review team requires a one-line electrical diagram showing circuit assignments, breaker amperage, and GFCI/AFCI device locations before they will issue a permit. This is a common rejection point: applicants often submit generic electrical plans without specifying which outlets are GFCI-protected or which breaker feeds the bathroom. If you're adding a new exhaust fan, you'll also need a dedicated 120-V circuit (no shared bathroom load), and the fan's CFM (cubic feet per minute) rating must match or exceed IRC M1505's requirement: 50 CFM for bathrooms under 100 square feet, plus 1 CFM per square foot for bathrooms over 100 square feet. A 5' x 8' bathroom (40 sq ft) needs minimum 50 CFM; a 10' x 12' master bath (120 sq ft) needs minimum 120 CFM. The exhaust duct must terminate outdoors (never into an attic, crawlspace, or garage), and condensation drain lines must slope to the exterior or back to the bathroom drain. Greenville inspectors will flag ductwork that terminates indoors or lacks condensation provisions.

Waterproofing is the third major code point. If you're converting a bathtub to a shower or installing a new shower enclosure, IRC R702.4.2 requires a moisture barrier (cement board, DensShield, or equivalent) with a secondary membrane behind all shower walls. Greenville's plan-review checklist asks: Are you using cement board + liquid membrane, cement board + sheet membrane, or a pre-assembled waterproofing system (e.g., Kerdi board)? The city does not mandate one system over another, but you must specify it on the permit application and be prepared to show evidence (product data sheets, installation photos) at the rough-framing inspection. A common rejection is submitting a permit with 'waterproofing per IRC standards' without specifying the actual product—the city will require a revision. Tile over drywall without a moisture barrier is not acceptable per code and will fail inspection. If you're moving the tub or shower to a new location, the rough plumbing inspector (before framing closes) will verify trap placement and duct routing, and the framing inspector will verify the moisture barrier is installed before drywall. A final inspection after tile installation confirms the waterproofing is complete and caulked properly.

Hunt County's expansive clay soils and seasonal water-table fluctuations create a specific local consideration: if your bathroom is on a concrete slab (common in older Greenville homes), any drain relocation that pierces the slab or requires sub-slab piping adjustments may need a licensed plumber to survey the existing utilities and confirm the new drain line does not conflict with electrical, gas, or structural elements. Greenville does not mandate a site survey, but many contractors request one because clay-slab homes are prone to settlement, and an improperly sloped drain in a relocated bathroom can lead to backups within 2–3 years. If your home is pre-1978, you must also assume lead paint is present and follow Texas Health and Safety Code § 88.002 and EPA RRP Rule protocols: any renovation disturbing painted surfaces over 6 inches requires containment, wet-wiping, and waste disposal by a certified lead-abatement contractor. Greenville's permit application asks for the home's year built; if it's pre-1978, the city will note that lead compliance is the applicant's responsibility, not the city's. Failure to follow lead protocols can result in EPA fines of $16,000+ per violation.

The permit application process in Greenville is initiated online through the city's permit portal or in person at City Hall. You'll need a detailed plan (or sketch) showing: (1) bathroom layout with existing and new fixture locations, dimensions, and supply/drain lines; (2) electrical plan with circuit assignments and GFCI/AFCI locations; (3) exhaust fan specification (CFM, duct size, termination location); (4) waterproofing specification if a new shower is involved; and (5) wall-framing changes if applicable. The city's staff will pre-screen your submission within 2 business days and either approve it for over-the-counter issuance or request revisions. Once approved, the permit is issued (fee payment required), and you can begin work. Inspections are scheduled via the online portal: rough plumbing (fixtures, drains, traps), rough electrical (circuits, outlets, GFCI/AFCI placement), rough framing/waterproofing (if applicable), and final (completed tile, fixtures installed, exhaust ducting sealed). Each inspection is typically available within 3–5 business days of request. Permit validity is 180 days; if work is not substantially started within that window, the permit lapses and must be re-applied (and re-paid for). Extensions are available but not automatic—contact the Building Department at least 10 days before expiration if you need more time.

Three Greenville bathroom remodel (full) scenarios

Scenario A

Vanity and tile swap, same plumbing location—1950s ranch in downtown Greenville

Your 1950s ranch home has a 5' x 8' bathroom with original tile walls, an old pedestal sink, and cast-iron drain lines. You want to install a new vanity with a cultured-marble top and replace the tile with subway tile, but the sink will occupy the same corner, use the same supply shutoffs, and drain to the existing trap. The toilet and bathtub stay in place. No electrical upgrades, no exhaust-fan changes. This is a surface-only cosmetic remodel and does not require a permit. You can purchase materials, hire a handyman or contractor, and work at your own pace. No inspections are needed. However, if the existing home was built before 1978 (likely for a 1950s ranch), you should assume lead paint is present on walls and trim; if you're removing old drywall or disturbing painted surfaces over 6 inches, you must follow EPA RRP Rule protocols (containment, HEPA-filter vacuuming, lead-safe work practices). A licensed lead-abatement contractor can handle this, or you can hire a certified RRP renovator. If you choose to ignore lead protocols and sell the home, you'll be liable for non-disclosure. Total cost: $2,000–$4,000 for vanity, tile, labor, and potential lead-abatement if required. Zero permit fees. Timeline: 2–4 weeks.

Scenario B

Move toilet and sink to opposite wall, new exhaust fan, existing tub—2000s suburban home in Hunt County

Your early-2000s suburban home has a 10' x 12' master bathroom with the toilet and single-sink vanity on the north wall and a separate bathtub on the east wall. You want to relocate the toilet to the west wall (new plumbing runs, new vent stack or tie-in to existing), relocate the vanity to the south wall (new supply lines, new drain), and install a new exhaust fan (currently there's a window-only ventilation). This is a major remodel requiring a permit. File a Standard Bathroom Remodel permit with the City of Greenville Building Department (online portal or in-person at City Hall). The permit application must include: (1) a dimensioned floor plan showing old and new fixture locations; (2) rough plumbing schematic with trap locations, drain slopes, and vent-stack routing (IRC P2706 requires proper trap-arm length; the city inspector will verify slope at rough plumbing inspection); (3) electrical plan showing the new exhaust-fan circuit (dedicated 120V, GFCI-protected outlet or hard-wired fan control) and existing bathroom circuits marked with GFCI/AFCI devices; (4) exhaust-fan CFM and duct-termination detail (minimum 100 CFM for a 120 sq ft bathroom per IRC M1505, duct to exterior wall or roof, condensation drain shown). The existing bathtub can stay in place (no waterproofing work unless you're replacing it). Plan-review time: 2–3 weeks. Once approved and permit is issued (fee: $300–$500 based on estimated labor and materials), you can begin demolition. Inspections required: rough plumbing (new drains, vents, traps), rough electrical (fan circuit, outlet placement), and final (fixtures set, fan ducting sealed, all connections tested). Each inspection books within 3–5 days. Total timeline: 4–6 weeks from permit to final approval. Cost: permit $300–$500, plumbing/HVAC labor $2,500–$4,000, electrical $800–$1,500, materials (fixtures, tile if you refresh) $1,500–$3,000. Total project: $5,100–$9,000.

Scenario C

Tub-to-shower conversion, new waterproofing, wall relocation—custom master-bath gut in southwest Greenville near expansion area

You're gutting a 1980s master bathroom (15' x 12') and converting an alcove bathtub to a large walk-in shower with a tiled bench, moving the vanity to a new wall, and slightly moving a bearing wall to create a larger closet adjacent to the bathroom. This is a full structural and plumbing remodel requiring a permit and multiple inspections. Because a bearing wall is being moved, you'll also need a structural engineer to provide a calculation and framing plan (cost: $500–$800). File a Major Bathroom Remodel permit with the City of Greenville Building Department. The application must include: (1) a full architectural/engineering plan showing the new wall location, bearing capacity, and header sizing (if the wall carries roof load); (2) a plumbing plan with the new drain pan under the shower (per IRC P2706, drain must slope to trap), relocated toilet and vanity drain lines, vent-stack routing, and trap-arm lengths verified; (3) waterproofing specification for the new shower—you must specify the system (e.g., 'cement board + Schluter Kerdi sheet membrane', 'Wedi prefab shower system', or 'foam shower base + PVC liner with mortar bed')—Greenville's inspector will verify this specification matches the product data sheets before issuing approval (this is a top rejection point); (4) electrical plan with new bathroom circuits (minimum 20A dedicated circuit for the vanity area, GFCI protection, and a separate circuit for the exhaust fan, which must be minimum 100 CFM per IRC M1505 for a 180 sq ft bathroom); (5) structural calculations for the moved bearing wall (engineer-signed and sealed). Plan-review time: 4–5 weeks because the structural component triggers additional review. Inspections: framing (bearing wall, window/door openings); plumbing rough (new drain pan, trap, vent lines, supply shutoffs); waterproofing (cement board + membrane verified before tile); electrical rough (circuits, outlets); and final (all fixtures installed, shower tile and waterproofing complete, caulk and sealant approved). Because of the structural work, a building official may conduct a mid-project structural inspection (after the wall header is set). Total timeline: 8–12 weeks. Cost: permit $500–$800, structural engineer $500–$800, plumbing/HVAC labor $4,000–$6,000, electrical $1,200–$2,000, materials (shower system, tile, fixtures, framing lumber) $3,500–$6,000. Total project: $9,700–$16,600. This is a 'Major Bathroom Remodel' in Greenville's terms because it exceeds $5,000 declared valuation.

Greenville's online permit portal and pre-screening workflow

Greenville's Building Department operates an online permit portal that allows homeowners and contractors to upload applications, track review status, and schedule inspections in real time. Unlike some Texas municipalities that require in-person filing and phone calls to book inspections, Greenville's system is integrated: submit your permit application (with sketches, electrical diagram, and any spec sheets), and the city's staff will respond within 2 business days with either conditional approval (for over-the-counter issuance) or a list of specific revisions needed before formal review. This pre-screening step is a city-level efficiency that saves applicants 1–2 revision cycles because staff flag missing GFCI/AFCI details, improper drain-slope notation, or incomplete waterproofing specs before the project enters formal plan review. Many applicants who upload sketches and product data sheets initially will receive approval within 5–7 days; those who submit vague hand drawings or generic 'per code' waterproofing specs will get a revision request within 2 days.

Once your permit is approved and issued (and the permit fee is paid), you can immediately schedule inspections through the online portal by selecting available inspection dates and times. Rough plumbing inspections book within 3–5 business days; the inspector (a licensed plumber employed by or contracted to the city) will verify trap placement, drain slope, vent routing, and trap-arm length against IRC P2706. If the inspector finds the trap arm exceeds the code maximum (typically 4 feet for a 2-inch drain line) or the slope is less than 1/4 inch per foot, they will issue a 'failed inspection' notice and give you 10 days to correct the issue and request a re-inspection.

Electrical inspections are similarly booked online and typically occur within 5 business days of request. The inspector will verify GFCI/AFCI protection at all bathroom outlets, check circuit breaker amperage and labeling, and confirm that any new circuits are properly sized and protected. If you've added a dedicated 20A circuit for the vanity area and a separate 20A circuit for the exhaust fan (both common in full remodels), the inspector will verify both circuits are GFCI and properly terminated. A common pass item is confirming that any existing bathroom circuits (e.g., lighting, mirror outlets) are also GFCI-protected; if they're not, the inspector may flag this and require retrofitting existing outlets with GFCI devices (cost: $30–$60 per outlet, labor $100–$200).

Final inspections in Greenville are scheduled after all work is substantially complete—tile is set and sealed, fixtures are installed, exhaust ducting is sealed, and electrical devices are covered. The final inspector will walk through and verify that all rough-inspection items have been corrected, that the waterproofing system is intact (no visible gaps in cement board or membrane seams), and that fixtures are properly functioning (exhaust fan draws air, GFCI devices trip when tested, water doesn't leak from drains). If the final inspection passes, the city issues a Certificate of Occupancy or completion notice, and your permit is closed. If the inspector finds defects (e.g., tile caulk is incomplete, exhaust duct has a gap), they issue a punch-list, and you have 10 days to correct and request a final re-inspection (typically no additional fee for re-inspections within the permit validity period).

Waterproofing and drainage: Hunt County clay soils and Greenville inspection practices

Hunt County's expansive Houston Black clay soils create unique drainage challenges for bathroom remodels, particularly in southwest Greenville and rural areas where homes sit on clay slabs or have shallow footings. Clay soils shrink and swell seasonally; if a relocated drain line is not properly sloped (minimum 1/4 inch per foot per IRC P2706) or if the trap is positioned in a low spot that collects standing water, you risk mold, odor, and backup issues within 1–3 years. Greenville's rough-plumbing inspectors are trained to check drain slope using a level and measuring tape; they expect to see slope marked on the permit plan. If you submit a plan showing a new drain line from a relocated bathroom vanity but the slope is not indicated, the inspector will either reject the inspection or conditionally pass it with a notation that slope must be verified at final inspection. To avoid this, use a laser level or transit during rough-in to confirm slope before calling for inspection.

Waterproofing systems in Greenville are strictly per IRC R702.4.2: any bathtub or shower enclosure must have a moisture barrier (cement board or equivalent) and a secondary membrane (liquid, sheet, or pre-assembled system). The city does not mandate one product over another, but you must specify the system in your permit application and provide product data sheets at the time of permit issuance. Common systems include Schluter Kerdi (pre-bonded waterproofing board), STPE (shower base + PVC liner + mortar bed), Wedi (foam board system), or traditional cement board + Hydro Ban (liquid membrane). Greenville's framing and waterproofing inspectors will expect to see the specified product installed before tile is applied. If you specify 'Kerdi board' on the permit but install standard cement board + liquid membrane, the inspector may flag this as a deviation and require correction before tile work proceeds. To avoid confusion, photograph the waterproofing system during rough-in and email the photo to the Building Department as confirmation.

A practical tip: if you're in an older Greenville home with a slab-on-grade bathroom (common in pre-1970 builds), any drain relocation that involves boring through the slab or adjusting sub-slab piping should be surveyed by a licensed plumber before permit filing. The plumber can confirm the new drain line does not conflict with existing gas lines, electrical conduit, or rebar in the slab. This survey costs $150–$300 and is optional per code but highly recommended in clay-soil areas where settlement and slab movement are common. Greenville inspectors appreciate seeing evidence (survey map, utility locate marks) that the new drain path has been vetted.

Common questions

Do I need a permit if I'm just replacing a toilet or vanity in the same location?

No. Replacing a toilet, sink, or vanity in the same spot with the same supply and drain connections is a fixture swap and does not require a permit. You can hire a plumber or do it yourself. However, if the existing home was built before 1978, you should follow EPA lead-safe work practices when disturbing painted surfaces. No permit, no inspection, no fees.

What happens if I move a toilet to a new location without a permit?

Moving a toilet requires new supply lines, a new vent stack or vent tie-in, and a new drain line—all of which must meet IRC P2706 trap and slope requirements. If you do this without a permit and it's discovered (e.g., during a home sale, insurance claim, or neighbor complaint), Greenville code enforcement can issue a stop-work order (up to $500–$2,000 in fines per day), and you'll be forced to obtain a retroactive permit and pass all inspections to bring the work into compliance. Retroactive permits often cost more ($400–$600 plus engineer certifications) and may require destructive inspection (opening walls) to verify code compliance. It's cheaper and faster to pull the permit upfront.

How much does a bathroom permit cost in Greenville?

Permit fees in Greenville are typically 1–2% of the declared project valuation. A $5,000 remodel costs $50–$100 in permit fees; a $10,000 remodel costs $100–$200. Most bathroom remodels fall in the $200–$800 fee range. Exact fees are calculated when you submit your application; the city will quote the fee before you pay. There are no hidden fees, but if you later amend the permit (e.g., add a second exhaust fan), you may owe an amendment fee ($50–$150).

Can I do the electrical work myself, or do I need a licensed electrician in Greenville?

Greenville requires that electrical work in a bathroom remodel be completed by a licensed electrician if you are not the owner-builder of an owner-occupied home. If you are the owner and the property is your primary residence, you may do the electrical work yourself, but you must still obtain an electrical permit (included in the bathroom remodel permit) and pass rough and final electrical inspections. If you hire a contractor who is not licensed, the permit will be rejected. Most homeowners hire a licensed electrician because GFCI/AFCI specifications and circuit sizing require expertise.

What is a GFCI outlet, and do I need one in my bathroom remodel?

A GFCI (Ground-Fault Circuit Interrupter) outlet is a safety device that detects electrical faults (ground faults) and cuts power in milliseconds, preventing electrocution. Per NEC Article 210 and IRC E3902, all bathroom countertop outlets and receptacles within 6 feet of a sink must be GFCI-protected. GFCI protection can be provided by a GFCI outlet itself (with a test/reset button) or by a GFCI-protected circuit breaker in the breaker panel. Greenville's electrical inspector will verify GFCI protection at rough and final inspection. If you're adding new bathroom circuits, they must be on a GFCI breaker or have GFCI outlets installed.

Do I need a permit for a new exhaust fan in a bathroom?

Yes. Adding a new exhaust fan (or upgrading an existing one) requires a permit because it involves new ductwork, a new electrical circuit, and ventilation-capacity design. Per IRC M1505, the fan must have a CFM (cubic feet per minute) rating matching your bathroom size: minimum 50 CFM for bathrooms under 100 sq ft, plus 1 CFM per sq ft over 100 sq ft. The duct must terminate to the exterior (never into an attic or crawlspace), and a condensation drain must be installed if the duct passes through unconditioned space. Greenville's inspector will verify duct termination and condensation drainage at rough inspection.

If I'm converting a bathtub to a shower, what waterproofing system does Greenville require?

Greenville does not mandate a specific waterproofing system but requires one that complies with IRC R702.4.2: a moisture barrier (cement board, DensShield, foam board, or pre-assembled system) and a secondary waterproofing membrane (liquid, sheet, or integrated into the barrier). Common systems are Schluter Kerdi (pre-bonded board), Wedi foam system, or traditional cement board plus Hydro Ban liquid membrane. You must specify your system in the permit application and provide product data sheets. The framing inspector will verify the system is installed correctly before tile work. Improper waterproofing is the top cause of bathroom failures and mold within 3–5 years.

How long does a bathroom permit take in Greenville?

A Standard Bathroom Remodel (under $5,000 valuation, fixture relocation or new exhaust fan only) typically takes 2–3 weeks for plan review and over-the-counter approval. A Major Bathroom Remodel (over $5,000, structural work, or multiple changes) takes 3–5 weeks for full plan review. Once permitted, inspections book within 3–5 business days each. Total project timeline from permit submission to final approval is usually 4–6 weeks for standard remodels and 8–12 weeks for major remodels with structural work. Delays can occur if revisions are requested during plan review or if inspections fail and corrections are needed.

Is my 1975 home subject to lead-paint rules in a bathroom remodel?

Yes. If your home was built before 1978, lead paint is presumed present. Any renovation in a bathroom that disturbs painted surfaces over 6 square inches (e.g., removing drywall, scraping old tile adhesive) requires compliance with the EPA RRP (Renovation, Repair, and Painting) Rule: the work must be performed by a certified RRP renovator, the work area must be contained, and lead-contaminated dust must be cleaned with HEPA-filter vacuums. Failure to comply can result in EPA fines of $16,000+ per violation. You can hire a certified lead-abatement contractor to handle this for $500–$1,500. Greenville's permit application asks for your home's year built; if pre-1978, the city will note that RRP compliance is your responsibility. Document your RRP compliance (contractor certification, photo evidence) and retain it in case of future sale or audit.

What if I hire a contractor who doesn't pull a permit—can I still get my permit later?

Yes, but it's complicated and expensive. If work has already been done without a permit, you can file a retroactive permit with Greenville's Building Department. The inspector will likely require destructive inspection (opening walls, cutting into tile) to verify the work meets code. Retroactive permits usually cost 50–100% more than the original permit fee ($400–$600), and you may be required to hire a licensed engineer to certify compliance. Additionally, if the city determines the work is deficient, you'll be ordered to correct it at your expense. It's much cheaper and faster to require the contractor to pull the permit before work begins.
