Homewood bathroom remodel permits—the key details

Homewood Building Department requires a permit for any bathroom remodel involving fixture relocation, plumbing changes, electrical circuit additions, exhaust-fan installation, or wall modifications. The triggering rule is straightforward: if you're roughing-in plumbing (running new supply or drain lines) or roughing-in electrical (adding circuits, installing new outlets or switches), a permit is required. The city enforces IRC P2706 (drainage fittings and trap geometry) and IRC M1505 (exhaust-fan ventilation), which means any relocated drain must maintain proper slope (1/4 inch per foot), trap-arm length must not exceed 6 feet for a 2-inch drain, and exhaust ducts must terminate outside the conditioned space with a dampered hood. For electrical work, IRC E3902 mandates GFCI protection for all bathroom receptacles within 6 feet of the sink, and most bathroom lighting now also requires AFCI (Arc-Fault Circuit Interrupter) protection if it's a new circuit. These are code minimums, not suggestions—plan-review staff will flag missing GFCI or AFCI notation on your electrical schematic.

Waterproofing is the most common point of failure in Homewood bathroom permits. IRC R702.4.2 requires a continuous water-resistant or waterproof layer (the 'shower pan') under tile in wet areas. The code allows several methods: standard cement board plus liquid waterproofing membrane, pre-assembled waterproof shower-pan liners, or specialized waterproof drywall products (like cement board with integrated membranes). Homewood plan reviewers will ask you to specify exactly which system you're using—'waterproofing' is not enough. If you're converting a tub to a shower or vice versa, the change in water assembly triggers waterproofing review because shower pans have stricter requirements than tub surrounds. Cement board alone does not meet the code; it must be paired with a separate waterproof membrane or you use a pre-fab system that integrates waterproofing. This is not negotiable, and it's one of the top reasons Homewood issues plan-review comments.

Exhaust-fan venting is another detail-heavy requirement. IRC M1505 requires bathroom exhaust fans in spaces without a window, and even if a window is present, modern code prefers dedicated mechanical exhaust. The duct must run directly to the exterior (not into an attic, soffit, or shared duct), and it must terminate with a dampered, insect-proof hood. Ducts longer than 25 linear feet should be 6-inch diameter rather than 4-inch to reduce noise and back-pressure. Homewood reviewers will ask for the duct routing plan—they want to see it exiting the roof or gable wall, not terminating in a soffit or attic. A common miss: builders run the duct to a soffit vent (thinking it vents outside) but it actually recirculates humid air into the attic. Homewood's plan-review comments will catch this and require revision before you can proceed.

Fixture-relocation rules hinge on drain-geometry constraints. If you're moving a toilet to a new location, the rough drain (the 3-inch or 4-inch vent-stack opening) must be within 6 feet of the trap in a horizontal run, and the slope must be consistent. A toilet relocated more than a few feet may require a new vent-stack, which means cutting through joists or the roof—expensive and code-regulated. Similarly, moving a sink drain may require a new trap arm and connection to the main stack. Homewood requires a plumbing plan showing all relocations, trap locations, and vent connections. If you don't have a licensed plumber drawing this, the permit office will ask you to hire one; DIY plumbing plans are rarely approved unless the homeowner is a licensed contractor.

The permitting process in Homewood is straightforward but requires completeness. Submit your permit application (available through the city's online portal or at City Hall) with a one-page bathroom remodel sketch showing fixture locations, electrical outlet/switch/GFCI placements, exhaust-fan duct routing, and waterproofing system description. If fixture relocation, plumbing changes, or new electrical circuits are involved, attach a basic plumbing or electrical plan (a licensed contractor's plan is preferred but not always required for owner-builder projects; check with the permit office). The permit fee is typically $200–$500 depending on valuation (usually estimated at 10–15% of remodel cost). Plan review takes 1–3 weeks; if comments are issued, resubmit revised plans (usually 1 resubmission cycle). Once approved, you'll schedule rough plumbing and electrical inspections before drywall, then final inspection after all finishes are complete. Most Homewood bathroom remodels clear final inspection within 4–6 weeks of permit issuance if inspections are coordinated promptly.

Three Homewood bathroom remodel (full) scenarios

Homewood's plumbing code and drain-geometry traps

For tub and shower drains, IRC P2706 also specifies that the overflow outlet (if present) must drain into the trap above the weir (the highest point of the trap). This seems simple but is often missed when a tub is relocated. If you're moving the tub, ensure the overflow line connects to the drain arm above the trap seal, not below it, or you'll get a rough-plumbing rejection. Homewood's inspectors also check for proper pitch on the tub drain line—same 1/4-inch-per-foot slope rule. Older homes (1960s–1980s) in Homewood sometimes have undersized drains (1.5-inch for tub/shower instead of modern 2-inch); if you're roughing a new drain in a remodel, use 2-inch minimum per current code. The 1.5-inch drain is outdated and code-compliance requires upgrade if you're adding or relocating.

Waterproofing and shower-pan specifications for Alabama's warm-humid climate

Tub-to-shower conversions in Homewood require a two-part waterproofing change: (1) the new shower surround must use the waterproofing system (cement board + membrane or pre-fab), and (2) the old tub deck waterproofing must be removed or sealed if it's being left in place as a curb. If you're demolishing the old tub and building a new shower curb, the entire wet assembly is new and must comply with R702.4.2. If you're keeping the old tub deck and building a shower wall over it, you must ensure the old deck waterproofing is intact or replace it. Homewood's rough inspection will look at this before drywall. A note on adhesive: do not use standard tile adhesive (thinset without polymer) on waterproofed surfaces; use a waterproof adhesive or epoxy mortar per the membrane manufacturer's spec. Homewood reviewers sometimes note this in plan comments, but it's often missed during construction, leading to failed inspections.
