Del Rio full bathroom remodel permits — the key details

The City of Del Rio Building Department requires a permit for any bathroom remodel that involves fixture relocation, new electrical circuits, tub-to-shower conversion, exhaust-fan installation, or wall movement. The threshold is clean: if the fixture stays in the same location and you're only replacing the fixture itself (toilet, faucet, vanity cabinet), no permit is needed. But the moment you move a toilet from one wall to another, add a new exhaust duct, or create a wet wall for a relocated shower, you cross into permit territory. The city processes applications at the Building Department counter during business hours (typically Monday–Friday, 8 AM–5 PM); there is no formal online filing system as of early 2024, though the city is developing one. Submittals require a plot plan showing the property, a floor plan of the bathroom with fixture locations and new plumbing runs, electrical layout showing GFCI/AFCI circuits, and (if applicable) a waterproofing detail for any tub or shower relocation. The city references the 2015 IRC for plumbing (IRC P2706 on drain fittings), electrical (IRC E3902 on bathroom GFCI), ventilation (IRC M1505), and waterproofing (IRC R702.4.2), but does NOT adopt Texas-specific amendments that would relax these rules.

Waterproofing and exhaust ventilation are the two areas where Del Rio inspectors flag the most rejections. If you are converting a bathtub location to a shower or vice versa, the city requires a written specification of the waterproofing system — cement board or equivalent with a liquid-applied membrane, or a pre-fabricated shower pan system. Submitting a plan that says 'tile and drywall' without naming the waterproofing assembly will be rejected; you must be explicit. This is because Del Rio's climate (hot and humid, especially in summer) creates high moisture loads in bathrooms, and the city has seen costly water-damage claims traced to inadequate waterproofing on relocated showers. Similarly, any new exhaust fan must be ducted to the exterior; ducting into the attic is not permitted and inspectors will not pass the rough-in if they find it. The duct must be sized per IRC M1505 (minimum 4 inches for most bathrooms, larger if serving multiple spaces) and terminated with a damper or louver that closes when the fan is off. If you're adding exhaust ventilation for the first time, show the duct route and termination location on your plan; don't assume the inspector will accept 'standard practice.'

Electrical work in bathrooms is heavily regulated. All bathroom receptacles must be GFCI-protected per IRC E3902.16; this includes the vanity, any outlets within 6 feet of the sink, and any outlets in the bathroom proper. If you're adding a new circuit (e.g., for a heated towel rack or a second vanity), you must show the circuit layout and confirm that the main panel has capacity. In Del Rio, homes built before 2000 often have undersized service (100 amp) that cannot accommodate major bathroom upgrades without a service upgrade; the city will flag this during plan review and require you to upgrade the panel before final approval. All bathroom lighting must be on a circuit separate from receptacles, per code. AFCI protection is required on all bathroom circuits in homes built after 2008; if your home is older and you're rewiring the bathroom, the city typically requires you to add AFCI to the new circuit, though it will not require retrofitting the entire existing bathroom system (a common point of confusion).

Del Rio permits for full bathroom remodels typically cost $200–$800 depending on the valuation of the work. The city uses a formula tied to the estimated cost of labor and materials; a straightforward fixture relocation and tile work might run $300–$400, while a high-end remodel with custom wet-room waterproofing and new electrical service could reach $700–$800. The permit fee does not include inspection fees (plan review is bundled, but electrical and plumbing inspections are often separate and may carry additional small fees of $50–$100 each). Plan review typically takes 2–5 weeks in Del Rio; the city does not offer expedited review. Once the permit is issued, you must schedule inspections for rough plumbing (before walls close), rough electrical (same), and final inspection. If walls are being moved, framing inspection may also be required. The timeline from permit issuance to final sign-off is typically 4–8 weeks, depending on how quickly you schedule inspections and whether any corrections are needed.

Owner-builders are allowed to pull permits for owner-occupied homes in Del Rio; you do not need a contractor's license to apply, but you must be the property owner and sign the permit as such. This route saves contractor markups but requires you to handle all submittals, inspections, and code compliance yourself. If you hire a licensed electrician or plumber to perform the work, that contractor can also pull the permit on your behalf (and some will, as part of their service); in that case, make sure the contract specifies who is responsible for obtaining the permit and paying the fee. Del Rio does not allow homeowner-pull permits for commercial or investment properties; if this is a rental unit or non-owner-occupied residence, a licensed contractor must pull the permit. Pre-1978 bathrooms require lead-paint testing and containment if any painted surfaces are disturbed (walls, trim); this is a federal EPA requirement and Del Rio enforces it. If lead is present, you must hire a certified lead-abatement contractor; the cost is separate from the permit but affects your timeline. Do not assume your bathroom is lead-free; testing is inexpensive ($200–$400) and is strongly recommended before you begin work.
