Geneva full bathroom remodel permits — the key details

Geneva requires a permit for any bathroom remodel that involves fixture relocation, new circuits, exhaust fans, tub-to-shower conversions, or wall moves. The threshold is intentionally broad: the 2021 IBC, adopted by Illinois and enforced by Geneva's Building Department, treats bathroom plumbing as critical infrastructure, so even a 3-foot toilet relocation must show rough plumbing and final inspection compliance with IRC P2706 (drainage and venting), IRC P2904 (drain trap sizing), and trap arm run limits (maximum 1/4-inch drop per 1 foot of length under IRC P3201.7). Electrical work triggers an even more stringent path: any new circuit—including the dedicated 20-amp circuit for an exhaust fan—must comply with NEC Article 210 (branch circuits), IRC E3902 (GFCI protection for all bathroom receptacles and lights within 6 feet of a tub or shower), and AFCI protection for all branch circuits serving bathroom outlets if installed after 2023 (per recent Illinois code amendments). The permit application form, available on the city's website or at City Hall, requires a site plan (showing where the bathroom is on the lot), electrical plans (showing circuit routing, breaker amperage, and GFCI/AFCI labels), and plumbing plans (showing trap sizing, vent routing, and fixture locations). Do not assume that hiring a licensed plumber or electrician exempts you from pulling a permit; Geneva explicitly requires the permit to be pulled before work begins, and the licensed tradesperson's work still needs city inspection sign-off.

Waterproofing is the single most-scrutinized element in Geneva bathroom permits. If you are converting a tub to a shower or building a new shower enclosure, IRC R702.4.2 requires a continuous impermeable barrier behind the shower wall. Geneva's Building Department has flagged many permits for insufficient waterproofing documentation: you must specify the exact system (e.g., 'cement board plus elastomeric membrane per ANSI A118.10' or 'Schluter-KERDI membrane' or equivalent) on the plan or in a spec sheet. Drywall alone is not acceptable; gypsum board requires a secondary membrane. If you are keeping an existing tub and only replacing the faucet or valve, no new waterproofing is required, but if the tub surround wall is being opened (even to relocate the valve), the surround must be brought up to current code, which often means removing existing tile, stripping back to studs, and installing a new waterproofing layer. This is a major scope jump (and cost jump) that many homeowners discover mid-project; getting a pre-permit site visit or written pre-construction confirmation from the Building Department is worth the 20 minutes. Pressure-balanced or thermostatic mixing valves are now strongly recommended by code and sometimes required if existing valve is being touched; Geneva does not mandate this retroactively for cosmetic faucet swaps, but any new plumbing work involving the main shut-off or supply lines should specify a code-compliant valve.

The exhaust fan requirement is often misunderstood. IRC M1505.2 requires a bathroom exhaust fan ducted to the outdoors with a minimum CFM rating based on bathroom square footage (typically 50 CFM for bathrooms under 100 sq ft, plus 1 CFM per additional sq ft). The duct must terminate through the roof or exterior wall with a damper, and the duct run cannot be longer than 25 feet (or longer if using larger duct diameter and low-friction fittings). Many Geneva permits are rejected because the exhaust plan does not show the duct termination or the CFM spec of the fan. If you are adding a new exhaust fan—even replacing an existing one with a higher-CFM unit—you need plan approval. If the existing fan duct is crushed, disconnected, or venting into the attic, the permit process will flag this, and you'll be required to fix it. Inline fans (ducted through the attic but terminating in a soffit) are marginally acceptable but highly disfavored; the Building Department will ask you to tie the duct to a roof penetration if feasible. Humidity and condensation damage in bathroom remodels is a major lawsuit risk, so Geneva takes duct routing seriously.

GFCI and AFCI protection is mandatory and often missed on initial submissions. Every outlet within 6 feet horizontally of a tub or shower basin (or within 6 feet of the outside edge of the tub/shower platform) must be GFCI-protected per NEC 210.8(A)(1). This includes vanity outlets, lighting circuits (if they cross the 6-foot boundary), and any new circuits you add. Many homeowners think 'one GFCI outlet at the vanity' is enough; it is not. The entire circuit may need GFCI protection, or you may need multiple GFCI outlets or a GFCI breaker in the panel. Your electrical plan must clearly label all GFCI locations. If you are running new circuits, the initial plan often lacks this detail, and the Building Department will request a revised electrical plan before issuing a permit. Getting a licensed electrician to draw the plan is the safest route.

Lead-paint RRP (Renovation, Repair, and Painting) is a federal EPA requirement that Geneva enforces through the permit process and through coordination with the Illinois Department of Public Health. If your home was built before 1978 and you are disturbing more than 6 square feet of paint (in aggregate across the bathroom—walls, trim, window frames all count), you must hire an EPA-certified lead-safe renovation contractor or obtain an exemption (very narrow—mostly applies to disturbance under 1 square foot per component). The contractor must use containment, HEPA-filter vacuums, and wet cleaning, and produce a clearance report after work. Many full bathroom remodels trigger RRP because walls are opened, trim is removed, or old tile is chipped off (which disturbs paint underneath). This adds $2,000–$5,000 to project cost and an extra 2–3 weeks for testing and clearance. If you hire a contractor, verify they carry EPA certification and lead-safe training; if you pull a permit as an owner-builder, you are responsible for RRP compliance or hiring a certified contractor for the RRP portion. Geneva's Building Department does not administer RRP directly, but the city will note on the permit if RRP is triggered, and the final inspection cannot be signed off until the lead clearance is in hand.

Three Geneva bathroom remodel (full) scenarios

Waterproofing and shower pan requirements in Geneva — what the Building Department really inspects

Geneva's Building Department has seen water-damage litigation from failed shower pans and knows that waterproofing is the linchpin of a durable bathroom remodel. IRC R702.4.2 requires a continuous impermeable barrier (membrane) on all surfaces that will be wet. This means studs, bottom plates, and blocking must be covered by either: (1) cement board (min 1/2 inch thick per ANSI A118.4 or A118.5) plus a layer of elastomeric waterproofing membrane rated for shower application (Schluter-KERDI, Hydroban, Aqua Defense, or equivalent); (2) a liquid-applied membrane per ASTM C1182; or (3) a waterproofing board system designed as a complete assembly (Wedi, Kerdi-Board). Gypsum drywall alone is not acceptable, even with paint or caulk; the Building Department will reject any plan that proposes drywall in a wet zone without a secondary waterproofing layer. Many permits submitted to Geneva lack a specific waterproofing spec, and the Department issues a request for information (RFI) asking the applicant to 'specify the waterproofing system.' This adds 1–2 weeks to the plan-review cycle. To avoid this, include the product name and ANSI standard on your plan, and provide a product data sheet (PDF) with the application. If using cement board and membrane, note the cement board brand, mesh tape type (use alkali-resistant mesh for cement board), thinset mortar type (must be mold-resistant), and the membrane brand and thickness. For modern builder-friendly systems like Schluter-KERDI, the spec is simpler because KERDI is designed as an integrated system, but you still need to note it explicitly.

The shower pan itself—the floor of the shower—is a separate waterproofing concern. IRC P2709 requires a sloped floor to a drain with a minimum 1/8-inch drop per foot toward the drain. If you are using a traditional mortar bed pan (still allowed but labor-intensive), the mortar must slope correctly, and a waterproofing membrane must be installed under the mortar bed or as an integral part of the assembly. Many newer bathrooms use a pre-sloped base (Pan America, Laticrete, or similar) or a waterproofing floor system (Wedi, Schluter, etc.) that includes the slope and membrane in one assembly. Geneva's inspectors will want to see the pan detail on your plan or in a spec sheet, and they will verify the slope at rough inspection. If the slope is inadequate, water will pool and eventual ly rot the subfloor and supporting structure. This is a final-inspection item: the inspector will often pour water on the floor and watch it flow to the drain to confirm proper slope.

One underestimated cost in Geneva remodels is vent stack relocation. If your relocated toilet drain is more than 5 feet from the existing main vent stack, and the trap arm run exceeds 1/4-inch drop per foot of length (IRC P3201.7), a new vent is required. In many ranch homes and two-story colonials, the main stack is in or near the kitchen, leaving bathrooms at the far end of the home. Running a new 2-inch ABS vent from the toilet drain up through the wall, through the attic, and terminating above the roof can cost $800–$1,500 in labor, plus $200–$300 in materials. This is often not anticipated in the initial project quote and is discovered during plan review. To avoid surprise, discuss trap arm distance and vent requirements with your plumber before finalizing plans.

Lead-paint RRP compliance for pre-1978 bathrooms in Geneva — what counts and what doesn't

If your Geneva home was built before 1978 and you are disturbing more than 6 square feet of paint in the bathroom (including walls, trim, windows, cabinet frames, and doors), the EPA's Renovation, Repair, and Painting (RRP) rule applies. This is a federal rule, not a local Geneva ordinance, but Geneva's Building Department enforces it as a condition of permit approval and final inspection sign-off. 'Disturbing' means sanding, grinding, cutting, demolition, or scraping that breaks the paint surface and releases lead dust. Removing tile by chipping (which removes paint and substrate underneath), stripping old caulk from painted trim, and opening walls to studs all count as disturbance. The key threshold is 6 square feet: if your toilet relocation requires moving a water-supply line through a wall that has 8 feet of painted studs exposed, that is disturbance, and RRP applies. If you are only re-caulking a trim joint without sanding, RRP does not apply.

If RRP applies, you have two options: (1) hire an EPA-certified Lead-Safe Renovation (LSR) contractor to perform all work that disturbs lead paint; or (2) obtain a lead exemption from the Illinois Department of Public Health (rare and only available for very minor work, typically under 1 square foot per component). Most homeowners choose option 1 and budget $2,000–$5,000 for LSR contractor labor on a full bathroom gut remodel. The contractor uses containment barriers (plastic sheeting taped to the floor, walls, and openings), HEPA-filter vacuums and wet cleaning to avoid airborne dust, and all debris is double-bagged as lead waste. After work, a HEPA-certified lead-clearance technician collects dust samples from horizontal surfaces (windowsills, floors, counters) and tests them. If all samples pass (lead levels below 40 µg/ft²), a clearance report is issued. This report must be provided to the Building Department before the final inspection is signed. Timeline is 1–2 weeks after work completion for sampling and lab turnaround. If you hire the LSR contractor as a general contractor for the full project, they often bundle LSR into their labor cost. If you hire a non-certified general contractor, you must separately hire an LSR contractor for the RRP-disturbing work, which adds complexity and cost.

Many homeowners attempt to avoid RRP by hiring a general contractor and never explicitly asking about lead compliance. This is a liability trap. If the permit application notes that the home was built pre-1978 (which the Building Department can confirm from county records), the permit will include an RRP requirement notice. If the final inspection reveals that lead-disturbing work was done without RRP clearance, the Building Department can issue a violation and demand remediation. In some cases, the entire bathroom has to be professionally cleaned and re-tested, which costs $5,000–$10,000. Insurance may also deny coverage if RRP was ignored. The safest path is to explicitly confirm RRP requirements with the city during permit review, hire an EPA-certified contractor (verify via the EPA's certified contractor database), and obtain the clearance report before final inspection.
