Bathroom Remodel Permit in Universal City, TX (2026)

Research by DoINeedAPermit Research Team · Updated May 2026

The Short Answer

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

Universal City's Building Department treats full bathroom remodels on a scope-trigger basis, not a dollar-threshold basis — a key distinction from some neighboring Bexar County jurisdictions that rely more heavily on valuation thresholds. If your project involves fixture relocation (even moving a toilet 2 feet) or any new drain lines, you will file a full plumbing permit with the city. Electrical work — new circuits, adding GFCI outlets, or a new exhaust fan on its own circuit — also requires a separate electrical permit. Universal City is in FEMA flood zone X (unshaded) in most areas, so flood-elevation concerns are typically not a primary driver, but the city enforces standard IRC P2706 drainage, IRC E3902 GFCI, IRC M1505 exhaust ventilation, and IRC R702.4.2 shower waterproofing as written in the 2015 IBC (which Texas adopted). The city's online permit portal allows most bathroom remodel applications to be submitted with PDFs of your proposed plumbing and electrical layouts; plan review typically takes 2–3 weeks for minor bathroom scopes and can stretch to 4 weeks if revisions are flagged. Because Universal City is a smaller municipality just north of San Antonio, permitting is generally more straightforward than in larger cities, with fewer layers of review — but inspections are mandatory and non-negotiable for any permitted work.

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

Stop-work orders and fines: If an inspector discovers unpermitted plumbing or electrical work during a later renovation or home sale inspection, Universal City can issue a stop-work notice and levy fines of $100–$500 per violation, plus require you to pull a permit retroactively and pay double fees.
Insurance claim denial: If a plumbing leak or electrical fire occurs in an unpermitted bathroom remodel, your homeowner's insurance may deny the claim entirely, leaving you liable for repairs ($5,000–$25,000+).
Home sale disclosure and title issues: Unpermitted work must be disclosed to buyers in Texas; failure to disclose can result in lawsuit liability and forced removal of the work at your cost ($3,000–$15,000), or the sale falling through entirely.
Lender refinance block: If you attempt to refinance and the lender's appraiser discovers unpermitted plumbing or electrical work, the refinance will be denied until the work is permitted retroactively and passes inspection.

Universal City full bathroom remodel permits — the key details

Universal City adopts the 2015 International Building Code (IBC) and follows Texas's plumbing and electrical codes. The critical rule that catches homeowners: any relocation of a drain line, supply line, or vent stack requires a plumbing permit and rough-in inspection before drywall closes. IRC P2706 specifies minimum pitch (1/4 inch per foot), trap-arm length limits (no more than 3 feet for most fixtures, 6 feet for kitchen sinks), and vent-stack sizing — and these are non-negotiable checkpoints in Universal City. A relocated toilet drain, for instance, must be pitched correctly and trapped within code limits, or the rough-in will fail inspection and drywall cannot proceed. Many homeowners assume moving a toilet 3 feet is 'cosmetic' and skip the permit; inspectors catch this during resale inspections or when a plumber complains to the city. The moral: if a single fixture moves, pull the plumbing permit. It costs $200–$400, takes 1–2 hours to apply online, and saves you thousands in fines or forced removal later.

Electrical work in bathrooms is heavily regulated. IRC E3902 mandates GFCI protection on all receptacles within 6 feet of a sink, tub, or shower — and that includes outlets in cabinets above the vanity. If you're adding a new circuit for a heated floor, a light fixture, or a ventilation fan, you will file a separate electrical permit with the city. Universal City's Building Department requires a single-line diagram showing the new circuit, breaker size, wire gauge, and GFCI/AFCI device locations. The exhaust fan circuit is its own line item: IRC M1505 requires a minimum 50 CFM exhaust fan (80 CFM if the bathroom is ≤100 sq ft) ducted continuously to the exterior — not to an attic or crawl space. Flexible duct is allowed but must be sealed at connections; rigid duct is preferred. The duct termination must be shown on your electrical plan. Inspectors will request photographic evidence of the duct route before you close the ceiling. Again, applying for this permit online takes 15–20 minutes and costs $150–$300; skipping it risks a failed final inspection or a forced retrofit at double cost.

Shower-to-tub conversions (or vice versa) trigger waterproofing code. IRC R702.4.2 specifies that bathtub and shower receptors must be lined with a moisture barrier — either a CPE/vinyl liner, a PVC sheet membrane, or a cement board-and-membrane assembly (Kerdi, RedGard, or equivalent). Many homeowners tile directly onto drywall or green board and assume it will hold; inspectors will catch this at rough framing and require you to tear out drywall and install proper waterproofing before the substrate is finished. The permit application requires you to specify your waterproofing system in writing and attach a product sheet (e.g., 'Kerdi system per Schluter specifications' or 'CPE liner per ASTM D6390'). Universal City inspectors are knowledgeable and will accept industry-standard systems, but vague answers like 'cement board and sealant' will get flagged for revision. Tub-to-shower conversions also require a new trap and drain assembly if the tub's existing drain is not code-compliant for the shower valve location; this adds cost and complexity. Budget $1,500–$4,000 for materials and labor on waterproofing alone, and plan for an extra 1–2 weeks of permitting time if the system needs revision.

Pressure-balanced (or thermostatic) shower valves are not explicitly required by Texas code, but many inspectors will recommend them for safety, especially if the home is occupied by children or elderly residents. The 2015 IBC does not mandate anti-scald valves in residential bathrooms, so you can use a standard single-handle or two-handle valve; however, if you are relocating the valve (moving the shower to a new wall), some inspectors may flag a standard valve as a best-practice miss. It's not a code failure, but you may be asked to revise the plan or sign off on a waiver. Choose a valve upfront and include the model number on your permit application to avoid confusion. Budget $150–$400 for the valve itself, depending on brand and features.

Universal City's permit timeline is typically 2–3 weeks for plan review and 1–2 weeks for scheduling inspections once rough-in work is complete. The city does not offer over-the-counter permits for bathroom remodels (unlike some larger Texas cities); all applications go through digital submission and email review. You will need a PDF set including floor plan, plumbing schematic, electrical one-line, and waterproofing specification. Once approved, you schedule the rough-in inspection (plumbing and electrical together, usually same visit), then framing/drywall inspection, then final inspection. If the project is small and no structural changes are made, the city may waive the framing inspection. Total permitting cost is typically $400–$800 (plumbing $200–$400, electrical $150–$300, building $100–$200 for a small remodel). Plan for 5–8 weeks from permit application to final sign-off; if revisions are needed, add 2–3 weeks per cycle.

Three Universal City bathroom remodel (full) scenarios

Scenario A

In-place vanity and toilet swap, new tile, new faucet — rear bathroom in Universal City proper

You're replacing the existing vanity with a new one in the same footprint, swapping out the toilet for a new model in the same location, adding a new faucet, and retiling the floor and surround. The old supply and drain lines remain in place; no new circuits are added (the existing outlet and light remain on their current circuits); the exhaust fan is not being touched. This is surface-only work and does not require a permit in Universal City. You may proceed with any licensed plumber and tile contractor, and no inspection is required. However, if your plumber needs to cut into drywall to access the old supply lines behind the vanity, be sure they properly patch and seal the drywall (no gaps that would violate fire-code requirements). The new vanity and toilet must be installed per manufacturer specs (proper p-traps, caulking, etc.), but this is the plumber's responsibility, not a permitting issue. Total cost for materials and labor: $2,500–$6,000. No permit fees. Timeline: 2–4 days of work, no inspection delays.

No permit required (fixture swap in place) | Licensed plumber optional but recommended | New tile, grout, caulk all DIY-friendly | Total cost $2,500–$6,000 | Zero permit fees

Scenario B

Toilet relocated 4 feet to new wall location, new drain line, new exhaust fan with duct — downtown Universal City bathroom

You're moving the toilet from its current spot to a new wall (4 feet away), which requires a new drain line and trap. You're also installing a new exhaust fan because the current one is broken and you want to upgrade to 80 CFM with rigid duct to the roof. The supply line will be extended in copper or PEX. This scope triggers both a plumbing permit and an electrical permit. For plumbing: you will submit a floor plan showing the old and new toilet locations, the new drain line route (including pitch, trap location, and vent-stack connection), and the trap-arm length calculation (must not exceed 6 feet for a toilet). The rough-in inspection will verify pitch, trap depth, and vent sizing before drywall is closed. For electrical: you will submit a one-line diagram showing the new circuit for the exhaust fan (typically a 20-amp circuit on a dedicated breaker), the fan CFM rating, and the duct termination location (roof cap or soffit, clearly marked). The GFCI outlet above the vanity must remain or be replaced; if you're adding a dedicated outlet for a heated bidet or towel rack, that's a separate line item on the electrical permit. Total permit cost: $600–$900 (plumbing $250–$400, electrical $200–$350, building $150–$150). Plan review will take 2–3 weeks. Once approved, schedule the rough-in inspection; plumbing and electrical will typically be inspected together in a single visit (1–2 hours onsite). After rough-in passes, you can close drywall and proceed to finish. Final inspection is required before you use the bathroom. Total project timeline: 6–8 weeks from permit to final sign-off. Contractor cost for labor (plumbing + electrical): $1,500–$3,000. Material cost (toilet, drain assembly, fan, duct): $600–$1,500. Total: $2,700–$5,400 plus permits.

Scenario C

Full gut and shower enclosure conversion (tub to walk-in shower, new walls, new waterproofing, relocated plumbing and electrical) — suburban Universal City ranch home

This is a major remodel: you're removing the existing tub and surround, moving the shower to a corner of the room with a new knee wall, installing a curbless walk-in shower with a CPE liner and Schluter Kerdi waterproofing system, relocating both the drain and the supply to the new shower location, and adding a new exhaust fan and a heated towel rack circuit. You're also moving the vanity to the opposite wall, requiring a new supply line. This scope requires plumbing, electrical, and building permits (building because a wall is being moved, even if it's a non-load-bearing interior wall). For plumbing: you submit architectural plans showing the new wall, the old and new drain locations, the new trap and vent assembly, and a detailed waterproofing specification (CPE liner 0.75mm, Schluter Kerdi board, and Schluter Kerdi membrane per Schluter TKB 2110-0092 or equivalent). The rough-in inspection will check drain pitch, trap location, vent sizing, and vent termination. For electrical: new circuits for the exhaust fan and heated towel rack, GFCI outlets per code, and any lighting changes. For building: the new knee wall must be framed per IRC R602 (stud spacing, nailing, blocking); if it's load-bearing (unlikely in a bathroom, but check), it requires structural calculations. The waterproofing inspection is critical: inspectors may request photos of the liner installation and membrane seams before drywall is applied. Plan review will take 3–4 weeks. Inspections are: rough framing (wall), rough plumbing (drain/vent), rough electrical (circuits), waterproofing verification (photos or inspection), drywall (if required), and final. Total permitting time: 7–10 weeks. Permit cost: $900–$1,200 (plumbing $350–$450, electrical $250–$400, building $300–$350). Contractor labor cost (plumbing, electrical, framing, tiling): $4,000–$8,000. Material cost (tile, fixtures, waterproofing, drywall): $2,500–$5,000. Total project cost: $7,400–$14,200 plus permits. This is the most complex bathroom remodel pathway and the one most likely to trigger revisions during plan review if waterproofing details are unclear.

Waterproofing and shower conversion in Universal City's humid climate

Universal City sits in Bexar County at the northern edge of the Texas Gulf Coast climate zone (2A/3A), with high humidity and occasional heavy rain. Shower and tub waterproofing failures are common in older homes that were built without proper membranes, and inspectors take this seriously. IRC R702.4.2 does not specify a single waterproofing method, but Universal City's building officials strongly prefer either a CPE/vinyl liner or a cement-board-plus-membrane system (Schluter Kerdi or equivalent). Do not attempt 'drywall and caulk' — it will fail inspection and you'll be forced to remove drywall and start over at double cost.

If you choose a CPE liner: the liner is installed under the cement board or tile bed, preventing water from ever reaching the stud framing. Schluter Kerdi (a polyethylene fabric bonded to both sides of a polyurethane foam core) is installed over cement board and sealed at all seams with Kerdi tape and thinset. Both methods cost roughly the same ($800–$1,500 in materials for a 5x8 bathroom), but Kerdi is easier for DIYers and more forgiving of minor imperfections. Budget an extra week for the waterproofing membrane to cure before you tile.

Common rejection: submitting a plan that says 'cement board with silicone caulk' is too vague. Universal City inspectors will ask for a specific product name and ASTM spec. Provide the Schluter product number or the CPE liner ASTM standard (e.g., 'CPE liner per ASTM D6390, 0.75mm') to avoid a revision request. Once waterproofing is approved, take photos during installation and have the inspector verify before drywall is installed; many contractors forget this step and end up tearing out tile later.

Electrical and GFCI requirements for Universal City bathroom remodels

Universal City enforces IRC E3902 strictly: all receptacles within 6 feet of a sink, bathtub, or shower must have GFCI protection. That includes the outlet above the vanity (even if it's 5 feet away horizontally), a heated towel rack outlet, a ventilation fan outlet, or any other plug location in the bathroom. If you are remodeling a full bathroom, the inspector will expect either a GFCI outlet in the bathroom itself or a GFCI circuit breaker in the main panel that protects all bathroom outlets. Many contractors install a single GFCI outlet near the sink and daisy-chain other outlets downstream (which works electrically), but Universal City's inspectors may require outlets visible in the bathroom (not buried in walls) to be individually GFCI-protected to avoid future maintenance issues.

If you are adding a new circuit for a heated floor mat, bidet, or towel rack, that is a separate line item on the electrical permit. Heated floors are typically 240V circuits and require a dedicated breaker; bidet seats and towel racks are 120V but may warrant a dedicated 20A circuit depending on amperage. Include all these on your one-line diagram upfront to avoid revisions. Test the GFCI outlet at rough-in inspection (an inspector will use a plug-in tester to verify the trip function) and again at final. If you do this work yourself (owner-builder), you will still need to have a licensed electrician pull the permit and supervise the rough-in inspection, or you will need a master electrician's sign-off; Universal City does not allow unlicensed owner-builders to perform electrical work on permits.

Common questions

Can I do a full bathroom remodel in Universal City without a permit if I hire a contractor?

No. If the scope includes fixture relocation, new plumbing lines, new electrical circuits, or a new exhaust fan, a permit is required regardless of who performs the work. The contractor should pull the permit on your behalf (or you can pull it yourself and hire them for labor). Skipping the permit risks fines, insurance denial, and home-sale complications.

How much does a full bathroom remodel permit cost in Universal City?

Permit costs depend on scope. A plumbing permit for relocated fixtures is $250–$400; an electrical permit is $200–$350; a building permit for wall changes is $150–$350. A full remodel (all three) typically runs $600–$1,200. Permit fees are separate from contractor labor and materials.

How long does plan review take for a bathroom permit in Universal City?

Plan review typically takes 2–3 weeks for small bathroom remodels (fixture relocation, new exhaust fan). Larger projects with wall changes and complex waterproofing specifications may take 3–4 weeks. If revisions are requested, add another 1–2 weeks. Total permitting timeline is usually 5–8 weeks from application to final inspection.

Do I need a plumbing license to relocate a toilet or shower in Universal City?

For a permitted project, no — you can hire a licensed plumber to do the work. However, if you are the owner of an owner-occupied home, you may be able to pull a 'homeowner permit' and do the plumbing work yourself (with a plumber supervising the rough-in inspection). Confirm with Universal City Building Department whether owner-builder permits are allowed for plumbing; policies vary by jurisdiction.

What happens if I convert my bathtub to a shower without a permit in Universal City?

A tub-to-shower conversion requires a plumbing and building permit because it changes the waterproofing assembly and the drain/valve configuration. If discovered during a resale inspection or neighbor complaint, you could face fines ($100–$500), forced removal of the work (costing $3,000–$10,000+), and home-sale complications. Permits are cheap and quick relative to these risks.

Is a heated bathroom floor allowed in Universal City, and does it need a permit?

Yes, heated floors are allowed. If you are adding a new 120V or 240V circuit for the heated mat or cable, you must file an electrical permit. The permit will require a one-line diagram showing the circuit, breaker size, and wire gauge. Plan-review time is 1–2 weeks; cost is $200–$350.

What waterproofing systems does Universal City accept for shower remodels?

Universal City accepts any waterproofing system that complies with IRC R702.4.2, which includes CPE or vinyl liners, PVC membranes, and cement-board-plus-membrane systems (Schluter Kerdi, RedGard, etc.). On your permit, specify the exact product name and ASTM standard (e.g., 'Schluter Kerdi per TKB 2110-0092') to avoid revision requests.

Do I need a separate exhaust fan permit if I'm replacing an existing fan with a new one in the same location?

If you are replacing the fan in-place with the same duct route and no new circuits, you may not need a permit (check with Universal City). However, if you are upgrading to a higher CFM, relocating the duct, or adding a new circuit, you will need an electrical permit. It's safest to call ahead and ask.

Can I close drywall before the rough plumbing and electrical inspection in Universal City?

No. Universal City requires a rough-in inspection before drywall or insulation is installed. If drywall is closed without inspection, you will be forced to remove it, have the inspection done, and patch/retape everything — adding weeks and thousands in cost.

If I install a bathroom vanity in the same location with new plumbing supply lines, do I need a permit?

If the supply lines remain within the existing wall cavity and no new drain line is added, you may not need a permit (surface-level work). However, if you are repositioning the supply lines to new locations behind the drywall, pulling a plumbing permit is the safe choice — cost is only $250–$400 and protects you at resale.
