Bathroom Remodel Permit in Celina, TX (2026)

Q: Do I need a permit if I'm just replacing my bathroom vanity and faucet in the same spot?

No, if the supply and drain lines are reused in their existing locations, vanity and faucet replacement is a cosmetic project and exempt from permitting in Celina. If you discover that you need to re-route the plumbing supply or drain lines—even slightly—that triggers a permit. Owner-builders and handymen can do this work without a contractor license; no inspections are required.

Q: My home was built in 1975. Do I need lead-paint testing before my bathroom remodel?

Lead-paint testing is not required by Celina's Building Department, but EPA RRP regulations apply to any interior disturbance over 6 square feet in pre-1978 homes. If you hire a contractor, they must be EPA-certified and follow containment protocols. If you do the work yourself and are EPA-certified, you must still follow containment. Budge $300–$600 for lead-safe practices, and disclose lead hazards to future buyers per Texas Property Code.

Q: How long does plan review take for a bathroom remodel permit in Celina?

Standard plan review is 10–15 business days. If the city requests clarifications (common for waterproofing systems or GFCI layouts), add 5–7 days per revision. Submitting a complete, detailed plan (with waterproofing assembly specified and electrical diagram included) speeds approval. Over-the-counter approvals are rare for full remodels; expect full review.

Q: Can I do the work myself as an owner-builder, or do I need to hire a licensed contractor?

Celina allows owner-builders to pull permits and perform their own bathroom remodels on owner-occupied homes. You must sign an owner-builder declaration, pull the permit, and be present for all inspections. You can hire licensed plumbers and electricians for those trades and have them sign off on their portions; the rest (framing, drywall, tile) can be owner-performed. Inspectors hold you to the same code standard as a contractor, and you are personally liable for any failures.

Q: What's the most common reason for plan rejections on bathroom remodels in Celina?

Unspecified or inadequate waterproofing systems. IRC R702.4.2 requires a water-resistant membrane behind all shower and tub walls. If your plan doesn't specify the membrane type (cement board alone is not enough; you need Kerdi, RedGard, or equivalent), the city will reject it and ask for resubmittal. Specify the product name, application method, and confirm your contractor has experience with it.

Q: Do I need a separate permit for adding a new bathroom, or is it the same as a remodel?

Adding a new bathroom is a different (and more stringent) permit than remodeling an existing one. A new bathroom requires structural review, foundation impact analysis (depending on location), and often requires a separate bathroom addition permit. Celina treats new vs. remodel as distinct projects. Remodeling an existing bathroom (even if you're moving everything around) is less complex than adding a new one from scratch.

Q: What if I'm converting a tub to a shower? Does that require a permit?

Yes, tub-to-shower conversions require a permit in Celina because the waterproofing assembly changes (IRC R702.4.2). Even if the plumbing drain and supply stay in the same location, the wall substrate and membrane must be designed for shower spray, which is different from a tub surround. Plan review will focus on the waterproofing detail. Expect the same 10–14 day review timeline as a full remodel.

Q: How much does a bathroom remodel permit cost in Celina?

Permit fees in Celina range from $300–$800 depending on the estimated valuation of the project. Cosmetic work (vanity swap, tile update) is typically $300–$500 if it requires a permit (usually it doesn't). Full remodels with fixture relocation, new electrical, and exhaust fans run $500–$800. The fee is calculated as a percentage of estimated labor and materials, typically 1.5–2%. Inspection fees are usually included in the permit fee.

Q: Can I vent my exhaust fan to the attic instead of outside?

No, IRC M1505.1 requires exhaust fans to terminate to the exterior (through the roof or wall). Venting to the attic is a code violation in Celina and will fail inspection. If the ductwork must run through the attic to reach an exterior wall or roof, the duct itself must be insulated per IECC R403.2.8 (required in climate zone 3A) and slope downward to prevent condensation. Improper attic venting causes mold, moisture damage, and structural failure—Celina inspectors now flag this strictly.

Q: What inspections are required for a bathroom remodel permit in Celina?

Rough plumbing (before drywall or tile substrate closure), rough electrical (if new circuits added), and final inspection (after all finishes) are mandatory. Framing and drywall inspections are often waived if no structural changes are made, but all three above are non-negotiable. You must pass rough plumbing before covering any drains or supply lines. Rough electrical must occur before drywall is closed if new circuits are added. Schedule inspections in advance; the city typically responds within 2–3 business days.

The Short Answer

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

Celina's Building Department enforces the 2015 International Building Code (IBC) and International Residential Code (IRC) with Texas amendments, and the city's online permit portal requires submittal of plumbing and electrical plans for any fixture relocation or new circuits. Unlike some smaller Texas towns that rubber-stamp residential bathroom work, Celina requires full plan review for any project that alters drainage lines, adds GFCI-protected circuits, or installs new exhaust ventilation—meaning you'll wait 2–4 weeks for approval, not same-day. The city also enforces strict waterproofing documentation for tub-to-shower conversions (you must specify your waterproofing assembly—cement board plus membrane is most common) and requires permit-to-inspect for rough plumbing and electrical before drywall closure. Celina sits in IECC climate zone 3A central Texas, which means exhaust fan ductwork must be insulated if it runs through unconditioned space—a detail many homeowners miss. If your home was built before 1978, lead-paint disclosure and containment rules apply to any interior disturbance. Owner-builders (you, the owner-occupant) can pull permits and do the work yourself in Celina, but all inspections are mandatory.

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

Stop-work orders cost $300–$500 in fines plus a mandatory re-pull of the permit at 1.5× the original fee if the City of Celina Building Department discovers unpermitted work during a future inspection or complaint.
Insurance claims for water damage, mold, or electrical fire in an unpermitted bathroom remodel are typically denied, leaving you personally liable for remediation ($5,000–$50,000+ for structural damage).
Lender or refinance blocks: most banks and appraisers flag unpermitted bathroom work during underwriting, halting your loan until permits are retroactively obtained or the work is removed.
Resale disclosure: Texas Property Code Section 5.0061 requires seller disclosure of unpermitted work; failure to disclose invites litigation and can kill a sale or trigger rescission after closing.

Celina bathroom remodels—the key details

Celina Building Department requires a permit for any bathroom remodel that involves fixture relocation, new electrical circuits, exhaust fan installation, wall removal, or tub-to-shower conversion. The threshold is straightforward: if plumbing or electrical work goes beyond swapping a faucet or vanity in place, you need a permit. The city enforces 2015 IRC sections including P2706 (drainage fittings and slope), E3902 (GFCI protection in bathrooms—all receptacles within 6 feet of a sink or tub), M1505 (exhaust fan airflow and duct termination), and R702.4.2 (waterproofing assemblies for shower and tub enclosures). Permits are filed online through Celina's permit portal or by mail/in-person at City Hall. Plan review typically takes 10–15 business days; the city may request clarification on waterproofing systems, GFCI layout, exhaust duct routing, or trap-arm length if your new drain runs more than 12 feet horizontally (IRC P3005.2). You'll pay a permit fee of $300–$800 depending on the valuation of materials and labor (typically 1.5–2% of estimated cost). Inspections are mandatory: rough plumbing (before walls close), rough electrical (if circuits added), and final (after all finishes). No inspection = no certificate of occupancy or proof the work meets code.

Waterproofing for shower and tub conversions is Celina's most common plan-review sticking point. IRC R702.4.2 requires a water-resistant or waterproof membrane behind all wall surfaces in the tub or shower enclosure. Most homeowners and contractors use cement board (not drywall—drywall fails under spray) plus a sheet or liquid membrane (Kerdi, Schluter, RedGard, or similar). Celina's inspectors want to see the membrane specified on your submittal or on the contractor's scope; if you list 'tile and mortar' without specifying the backing, expect a rejection with a request to resubmit. If you're converting a tub to a walk-in shower, the waterproofing assembly changes the structural detail—that triggers a full remodel permit, not just a cosmetic swap. Schluter systems, Wedi foam, and PVC shower bases are also code-compliant; the city accepts any assembly that meets ASTM D6375 or equivalent. One contractor shortcut that fails inspection in Celina: using cement board without a liquid membrane underneath, then relying on silicone caulk alone. That's a rejection—plan for 3–4 days of rework and a re-inspection fee.

Electrical and exhaust requirements in Celina follow 2015 NEC with Texas amendments. All bathroom receptacles must be on GFCI-protected circuits (NEC 210.8(A)(1))—this applies to outlets near sinks, within 6 feet of tubs or showers, and also behind toilet areas if you're adding outlets. If you're only remodeling the tub area and not rewiring, many contractors miss that any new outlets in the bathroom area now require GFCI. The city requires a one-line electrical diagram showing GFCI breaker(s) or outlet-level GFCI protection; lack of this drawing is a common rejection. Exhaust fan ventilation is governed by IRC M1505.1: you need a fan rated for your bathroom square footage (typically 50–100 CFM), and the duct must terminate to the exterior (not to an attic or soffit). Here's Celina-specific: because the city sits in climate zone 3A, if your exhaust ductwork runs through an unconditioned attic or crawlspace, it must be insulated (IECC requirement)—uninsulated ducting causes condensation and mold, and Celina inspectors now call this out. The duct must also slope downward to the termination point and include a damper. Many DIYers and budget contractors vent to the attic; that's a code violation and a rejected inspection in Celina.

If your home was built before 1978, lead-paint rules apply to any interior disturbance in Celina, per EPA RRP (Renovation, Repair, and Painting) regulations. Any contractor (including owner-builders) who disturbs more than 6 square feet of painted surface must be EPA-certified and follow containment protocols. This doesn't stop your project, but it adds cost ($300–$600 for lead-safe work practices) and timeline. Celina's Building Department doesn't enforce EPA lead rules directly, but if you hire a contractor and fail to get lead-safe work done, you're liable to EPA and to buyers later. If you're the owner-builder (doing the work yourself), you must still follow containment, but enforcement is lower unless someone complains. For pre-1978 homes, budget an extra $500–$800 for lead abatement and testing, and disclose it on your permit.

Owner-builders in Celina can pull permits and perform their own bathroom remodels if the home is owner-occupied. You'll sign an owner-builder declaration, pull the permit yourself (online or at City Hall), and be responsible for all inspections and code compliance. The advantage: you save contractor markup. The downside: inspectors hold owner-builders to the same code standard as licensed contractors, and you're personally liable if something fails. If you hire a licensed plumber or electrician for those trades, they can sign off on their portions; the rest (framing, drywall, tile) can be owner-performed. Celina's permit office is open Monday–Friday, 8 AM–5 PM; call ahead or check their online portal to confirm hours and submission deadlines. Permits expire in 180 days if work hasn't started; if you're phasing the project, plan your timeline carefully to avoid re-pulling.

Three Celina bathroom remodel (full) scenarios

Scenario A

Relocating toilet and sink to opposite wall, existing tub stays, new exhaust fan—suburban Celina home, $8,000 project

You're moving the toilet from the west wall to the east wall (new drain line) and relocating the sink to a new vanity cabinet on the north wall (new supply and drain). The existing tub is staying in place, but you're installing a new exhaust fan with exterior ductwork. This is a full permit job in Celina. You'll submit plumbing and electrical plans showing the new drain slope (IRC P3005.1: minimum 1/4 inch per foot), trap location, vent-stack routing, and exhaust duct termination (must go through the roof or wall, not the soffit). The toilet drain will require a 3-inch line (IRC P3002.1); if your new line runs more than 12 feet from the vent stack, you'll need a wet vent or secondary vent—this is where inspectors often flag amateur layouts. The sink drain is 1.5 inches and must slope into the trap; if your new trap arm exceeds 2.5 feet in length (IRC P3005.2), it's a code violation. The electrical plan must show GFCI protection on all new outlets, and if you're adding a switched outlet for the exhaust fan (common), it needs to be on its own 20-amp circuit (no sharing with lights or other loads). Exhaust duct must be 6-inch rigid aluminum (or flexible vinyl if you use a short run), insulated if it passes through the attic, and terminating with a damper and hood outside. Permit fee: $500–$700 (valuation ~$8,000). Plan review: 10–14 days. Inspections: rough plumbing (before walls close), rough electrical (before drywall), final (after all finishes and duct sealed). Timeline: 4–6 weeks total if no plan-review rejections.

Scenario B

Tub-to-shower conversion, existing plumbing location unchanged, new waterproofing—1960s home in north Celina, $5,000 project

You're removing a cast-iron bathtub and replacing it with a 36x36 tile shower base in the same footprint. The supply and drain lines are staying in place (no relocation), but the wall assembly is changing because IRC R702.4.2 mandates waterproofing behind all shower wall surfaces. This requires a permit in Celina, even though plumbing fixtures aren't moving. Your plan must specify the waterproofing system: cement board plus sheet or liquid membrane (Kerdi, RedGard) is the standard. Drywall alone is not acceptable—inspectors will reject the plan and ask for clarification. If your home was built before 1978 (it was), EPA lead-paint rules apply; any disturbance of painted surfaces over 6 sq ft requires containment and EPA-certified contractors. The shower enclosure itself must be set on a proper shower base (not wood framing) or a slope-to-drain tile base with the waterproofing membrane underneath. The valve (mixing valve) must be pressure-balanced (ASSE 1016 standard) to prevent scalding. You're not adding electrical circuits here (assuming existing exhaust fan), so no GFCI update is needed, but the rough inspection will review the waterproofing and base before tile is set. Permit fee: $300–$500 (lower valuation because no plumbing relocation). Plan review: 7–10 days. Inspections: rough (waterproofing and base before tile), final. Timeline: 3–4 weeks if no rework. Common rejection: waterproofing system not specified or applicator not qualified (some inspectors require Schluter or Wedi certification)—budget an extra week if contractor needs re-training on membrane installation.

Scenario C

Vanity swap and tile update in place, no fixture relocation, existing bath—owner-builder project, $1,500 materials

You're replacing the existing vanity cabinet with a new one in the same location, swapping the faucet (same supply lines, just new compression fittings at the stub-outs), removing old tile and re-tiling the wall with new substrate, and updating light fixtures (using existing wiring). No drains are being moved, no new electrical circuits are added, no walls are coming down. This is a cosmetic bathroom project and does not require a permit in Celina. IRC exceptions for minor repairs and alterations allow vanity and faucet replacement in place without permit. The tile work, even though it involves removing old tile and substrate, is surface-only and exempt as long as you're not changing the waterproofing system behind the tile (e.g., not upgrading from drywall to cement board). If you encounter plumbing leaks while removing the old vanity and decide to re-run the supply or drain lines instead of reusing the existing stubs, that crosses into permit territory—but if you're just reconnecting to the old openings, you're fine. You can pull permits yourself as the owner-builder, or you can hire a handyman or tile specialist; neither requires a licensed contractor bond for this scope. Materials cost ~$1,500 (vanity $400, faucet $200, tile $400, labor ~$500 if DIY or $1,200 if hired). No permit fee. No inspections. Timeline: 1–2 weeks to complete. Caveat: if you discover rotten substrate or mold behind the old tile, and you end up tearing out drywall or framing to remediate, that structural repair might trigger a permit—but as long as you're surface-level, you're exempt.

Celina's waterproofing and plan-review process for bathroom remodels

Celina Building Department's most frequent rejection in bathroom remodel plan review is inadequate or unspecified waterproofing for tub and shower enclosures. IRC R702.4.2 is the code section, and it's non-negotiable: any wall surface that will be exposed to water spray or splash must have a water-resistant membrane behind the finish material. The city's inspectors now require the waterproofing product and installation method to be named on the submittal (not just 'tile and grout'). Cement board is the minimum substrate; drywall is not acceptable in wet areas. The membrane—whether sheet (Kerdi, Wedi), liquid (RedGard, Hydroban), or self-adhesive (Redgard Fabric Crack Prevention)—must be specified by brand or equivalent performance rating.

Plan-review timeline in Celina is typically 10–15 business days for a standard bathroom remodel, but rejections extend this by 5–7 days per round. The city's online portal allows you to upload PDF plans and receive comments back via email. If the inspector flags 'waterproofing system not specified,' you'll need to resubmit with product details, application instructions, and sometimes a photo of the installed assembly. Many homeowners and contractors think this is overkill, but Celina has seen mold and structural failures in bathrooms with inadequate waterproofing, so the scrutiny is justified. Your contractor or yourself (if owner-building) should have hands-on experience with the chosen waterproofing system; inspectors will ask to see sample work or credentials.

The city also enforces a strict inspection sequence: rough plumbing must be inspected before any drywall or tile substrate is installed. If you've already covered the plumbing with drywall, the inspector will ask you to cut access holes for visual inspection, adding cost and delay. Some contractors try to save time by tiling over unpermitted rough plumbing; Celina's final inspection will catch this, and you'll face a correction order. Budget for the rough inspection to take place after all framing and plumbing/electrical rough-in, but before any drywall taping, mudding, or substrate prep.

Climate zone 3A and exhaust ventilation requirements in Celina

Celina sits in IECC climate zone 3A (central Texas), which has specific HVAC and ventilation rules that trip up many bathroom remodelers. IRC M1505.1 requires exhaust fans in bathrooms; the capacity is based on the room's square footage (typically 50 CFM for a small bath, 100+ CFM for larger layouts). The duct must terminate to the exterior—not to an attic, crawlspace, or soffit—and must slope downward from the fan to the termination point to prevent condensation and ice damming. Here's the Celina-specific detail: if the duct runs through an unconditioned attic or crawlspace (which is common in central Texas homes with attics), the duct must be insulated per IECC R403.2.8. Many contractors in the area still use uninsulated flexible vinyl ductwork; this violates the code in Celina and will be flagged at rough electrical inspection.

The ductwork material and sizing matter too. A 6-inch flexible or rigid aluminum duct is standard; anything smaller (4-inch) is undersized for most bathrooms and creates backpressure, reducing fan efficiency. The duct must include a damper at the exterior termination (prevents cold air back-flow in winter) and a hood or cap (keeps out rain and critters). Celina's inspectors have become stricter about duct termination in the last few years, especially after seeing moisture and mold problems in attics. If your plans show exhaust venting to the soffit or attic, expect a rejection and a request to revise to through-wall or through-roof termination.

If you're adding a new exhaust fan as part of your remodel, the electrical circuit must be sized correctly: a 120V, 20-amp circuit is standard, and the switch and damper operation should be shown on your electrical plan. Some homeowners add a humidity sensor or timer switch to the exhaust fan; that's fine, but the basic circuit must still meet code. Celina's Building Department also enforces AFCI (Arc Fault Circuit Interrupter) protection on all circuits in bedrooms and living areas; bathrooms don't require AFCI, only GFCI, but if you're rewiring near a bedroom outlet, AFCI may apply to that circuit instead.
