Round Lake Beach bathroom remodel permits — the key details

Round Lake Beach Building Department enforces the 2021 Illinois Building Code with adoption of the 2021 IRC. The most critical code section for bathroom remodels is IRC E3902, which mandates GFCI (ground-fault circuit-interrupter) protection on all bathroom circuits within 6 feet of water sources — sinks, toilets, tubs, and showers. If your remodel adds new electrical circuits or relocates existing ones, the electrical plan must show GFCI outlets and specify the circuit type (standard 15-amp or 20-amp). A second mandatory requirement is IRC M1505: exhaust fans must be ducted to the outside (not to an attic or soffit) and sized for the bathroom square footage — typically 1 CFM (cubic feet per minute) per square foot, with a minimum of 50 CFM for a half-bath and 100 CFM for a full bath. Round Lake Beach reviewers will reject any application that shows a duct terminating indoors or that lacks CFM specification on the fan nameplate. For tub-to-shower conversions or new shower installations, IRC R702.4.2 requires a waterproofing assembly: typically 6-mil polyethylene sheeting, cement board, and a shower pan liner, or a waterproofing membrane system like RedGard or Schluter — the permit application must specify the exact system. Many homeowners skip this documentation, leading to rejection and a 1-2 week delay. If you are relocating any plumbing fixture (toilet, sink, shower valve), IRC P2706 and P2704 apply: the drainage arm from the fixture to the main stack cannot exceed 42 inches in length (this is a common failure point in Round Lake Beach plan reviews), and the vent stack must be properly sized and routed. Round Lake Beach also requires that all plumbing work be performed by a licensed plumber or the homeowner if owner-occupied; contractor affidavits and proof of plumber licensing will be requested at permit issuance.

Electrical work in a bathroom remodel must comply with IRC E3902 and E3906: all outlets within 6 feet of a water source must be GFCI-protected, and any new circuits must include a dedicated 20-amp circuit for the bathroom if you're adding appliances or a heated floor mat. The city's electrical inspector will test GFCI functionality at rough-electrical inspection — if the outlet doesn't trip within 25 milliseconds, the work fails and must be corrected. Additionally, any new lighting, exhaust fans, or heated-floor installations require a separate circuit diagram and specification sheet showing wire gauge, breaker size, and disconnecting means. Round Lake Beach does not allow GFCI protection via breaker alone on bathroom circuits in new or relocated wiring — the outlet itself must be GFCI-rated. This is a point of confusion for many homeowners and DIYers: a GFCI breaker in the panel is acceptable for protecting existing outlets only if they were grandfathered in before the 2021 code cycle, but any new or relocated bathroom work must use GFCI outlets. The permit application must include a one-line electrical diagram showing the panel, breaker size, circuit number, and outlet locations. If you are adding a heated floor mat or a ventilation fan motor with a humidistat, those items must be listed on the electrical plan with amperage and nameplate voltage.

Plumbing relocation and drainage sizing are the third critical path for bathroom remodels in Round Lake Beach. If you are moving a toilet, sink, or shower/tub to a new location, the drain line must be sized per IRC P2704 and must include a proper trap and vent. The most common code violation in Round Lake Beach bathroom remodels is a trap-arm length exceeding 42 inches (the maximum distance from the fixture outlet to the vent stack); reviewers measure this on the plan view and will reject designs that exceed the limit. The drain must slope at a minimum of 1/4 inch per foot toward the stack. If your remodel requires a new vent stack (i.e., the existing one is too far away or undersized), you will need to either run a new 2-inch vent through the roof or tie into an existing vent; the plan must show the vent routing, sizing, and termination location (minimum 12 inches above the roof or any window/door within 10 feet). Round Lake Beach allows individual bathroom vent fans to be ducted into a common vent, but only if properly sized and sloped — this is often overlooked in DIY designs. If your remodel includes converting a tub to a shower (or vice versa), the drainage and vent must be sized accordingly; a shower typically requires a 2-inch drain, while a toilet requires a 3-inch drain. The plumbing plan must include fixture-unit calculations and a branch drain diagram showing all slopes and connections. Many homeowners submit plans without this level of detail, resulting in a 'plan incomplete' rejection and a 1-2 week resubmission cycle.

Waterproofing for shower and tub installations is a frequently overlooked requirement in Round Lake Beach bathroom permits. IRC R702.4.2 mandates that all showers and tubs be lined with a water-resistant assembly that prevents water from penetrating framing or substrates. The standard approach is a cement-board substrate with a waterproof membrane (such as RedGard or Schluter), or a pan liner system. The permit application must specify the waterproofing system — just stating 'waterproofed per code' is insufficient and will trigger a request for clarification. Round Lake Beach reviewers will ask for the product name, installation instructions, and warranty; if you cannot provide this documentation, the plan review will be delayed by 1-2 weeks while you source the information. For conversions from tub to shower, this requirement is especially important because the structural assembly is changing; the framing must be reviewed to ensure adequate blocking and substrate support. If you are retiling an existing shower or tub without changing the substrate, waterproofing is typically not re-reviewed as long as the existing system is intact. However, if you are opening walls, removing or replacing substrate, or changing the fixture orientation, new waterproofing documentation is required. The city's inspector will perform a visual walkthrough at drywall stage (after taping and mudding but before tile) to verify that the waterproofing membrane is in place and properly sealed at penetrations (drain, valve, etc.).

Round Lake Beach's permit process for bathroom remodels typically follows a 3-5 week timeline from submission to rough inspection, with 2-3 additional weeks for finish inspection. The Building Department accepts over-the-counter applications for routine remodels if the application packet is complete: a one-page description, floor plan with dimensions, electrical single-line diagram, plumbing riser diagram (showing vent and drain routing), and product specifications for any new fixtures or waterproofing systems. If the application is incomplete, the city will issue a 'request for additional information' (RAI), and you will have 10 days to respond; failure to respond results in application denial and requires a restart. Once approved, you will receive a permit card, and you may begin rough plumbing and electrical work. Round Lake Beach schedules rough inspections within 5 business days of a request; the inspector will verify GFCI protection, vent routing, drain slope, and trap placement. If the work passes, you can proceed to drywall and finish stages. The framing inspection (if walls are opened) and drywall inspection occur before finish; the final inspection happens after all fixtures are installed and the room is complete. If you are an owner-builder (owner-occupied), you may perform plumbing and electrical work yourself in Round Lake Beach, but you must obtain a licensed electrician for any final inspection and sign-off; the permit fee does not change, but the inspection requirements are the same. If you hire a contractor, proof of contractor licensing and worker's compensation insurance is required at permit issuance. The city's online portal (accessible via the City of Round Lake Beach website) allows you to track permit status, schedule inspections, and view inspection reports in real-time, which is a significant advantage over many neighboring jurisdictions.
