Do I need a permit for a full bathroom remodel in
Medina, Ohio?

Medina, Ohio bathroom remodel permits — the key details

The City of Medina enforces the Ohio Building Code (2014 IBC edition with state amendments), and the threshold for a bathroom remodel permit is straightforward: any change that involves plumbing fixture relocation, electrical circuit addition, mechanical ventilation duct installation, structural changes (wall removal or framing), or waterproofing assembly work triggers a full permit. The key word is 'any' — even moving a toilet to a different wall, shifting a vanity cabinet that requires new supply and drain lines, or installing a new vent fan duct all require a permit application. If your project is purely cosmetic (in-place faucet swap, tile surround without changing the framing, new vanity cabinet that reuses existing rough-ins in the same location), you do not need a permit. Medina's Building Department interprets 'relocation' broadly: if the new fixture's drain-line run differs from the old one (different angle, different fitting configuration, or new trap requirements), that counts as relocation and requires a permit.

The most common code enforcement points in Medina are waterproofing documentation for shower assemblies (IRC R702.4.2 — cement board, membrane system, or equivalent product list required on the plan), bathroom GFCI/AFCI circuit separation (IRC E3902 — all 120V receptacles within 6 feet of the sink and all circuits serving the bathroom must be GFCI or arc-fault protected), exhaust fan duct termination (IRC M1505 — the fan must exhaust outdoors, not into an attic or crawl space, and the duct routing must be shown on the mechanical plan with the final termination location labeled), and trap-arm geometry on relocated drains (IRC P2706 — the horizontal drain line from fixture trap to main stack cannot exceed a slope of 1/4 inch per foot and must not exceed specific length limits based on pipe diameter — 5 feet for a 1.5-inch line is typical, but the plan must confirm this). Medina's Building Department does not automatically issue over-the-counter permits for full bathroom remodels; all submittals go to the plan examiner for a 7-10 business day review cycle. If the examiner flags issues (most commonly missing exhaust duct routing, insufficient waterproofing spec, or GFCI diagram unclear), you'll receive a request for more information (RFI), which adds another 3-5 days. Once the permit is issued, four inspections are typically required: rough plumbing (before walls are closed), rough electrical (before drywall), framing/drywall (if structural changes were made), and final (after all work is complete and passed rough inspections).

Electrical requirements in a Medina bathroom remodel center on GFCI protection (IRC E3902.1 requires GFCI protection for all 120V branch circuits in bathrooms, at receptacles within 6 feet of the sink, and for all wet areas), arc-fault protection on bedroom circuits (not typically the bathroom proper, but if the bathroom opens directly into a bedroom, clarification is needed on the electrical plan), and dedicated circuits for high-load equipment (an electric heated towel rack, for example, may need its own 20A circuit). If you're adding a new exhaust fan, the circuit feeding it must be shown on the plan, and the ductwork must be sealed and rigid (or flexible duct that meets UL 181 rated for that application). The permit examiner will ask for a line-by-line electrical plan showing circuit numbers, wire gauges, disconnect locations, and GFCI/AFCI placement. Medina does not allow generic 'per code' notes; the plan must be explicit.

Plumbing fixture relocation is the most common trigger for a full permit (as opposed to a cosmetic upgrade). If you move a toilet from the wall adjacent to the stack to an island position, a new trap arm must be run; if the run exceeds 5 feet (for a 1.5-inch line) or 10 feet (for a 2-inch line), you may need a separate vent-through or island vent, which adds complexity. Similarly, moving a sink to a new wall or adding a second sink requires a new trap arm and supply lines, and the configuration must be shown on the plumbing plan. Medina's examiners verify that all traps are individually vented or part of a proper vent stack, and the plan must clearly label each trap, the vent configuration, and the drain slope. If you're converting a tub to a shower or vice versa, the entire waterproofing assembly changes: a tub surround (typically ceramic tile over cement board) requires different waterproofing than a walk-in shower (which often requires a curb, a sloped base, a membrane system beneath finishes, and a secondary drain pan in some cases). The permit application must specify the waterproofing method (e.g., 'Schlüter KERDI membrane system with center drain, sloped mud base, and sealed seams per manufacturer'), and Medina's examiner will compare it to the IRC and the product data sheet to confirm compliance.

Timeline and cost for a bathroom remodel permit in Medina: the permit fee is typically $200–$600, calculated at about 1.5-2% of the estimated project valuation (a $25,000 remodel translates to roughly $375–$500 in permit fees). The fee calculation is based on the description of work you provide on the application; if you understate the scope (e.g., marking a full remodel as 'partial plumbing upgrade'), the examiner may recalculate the fee upward during plan review. Once you submit a complete application with plans, the review timeline is 7-10 business days for the first review; if the examiner issues an RFI, add another 5-7 days for resubmission and final issuance. Rough plumbing and electrical inspections are typically scheduled within 3-5 days of permit issuance; final inspection can occur 1-2 weeks after rough inspections pass. Total permitting and inspection timeline is typically 3-4 weeks from application to final sign-off. Medina's Building Department office is located at City Hall (verify the exact address and hours on the city website); you must hand-deliver or mail printed plan sets (typically three sets) and the signed application form. Digital submission is not available, so allow time for printing and delivery.

Three Medina bathroom remodel (full) scenarios

Waterproofing compliance for bathroom remodels in Medina: IRC R702.4.2 and common code violations

Medina's Building Department takes waterproofing seriously because Ohio's humid continental climate (Zone 5A) and glacial till soil create persistent moisture pressures. IRC R702.4.2 requires that all wall and floor surfaces adjacent to bathtubs and showers be waterproofed. The code allows several methods: (1) cement board with a waterproofing membrane (traditional), (2) proprietary systems like Schlüter KERDI, (3) acrylic or polyurethane liquid-applied membranes, or (4) sheet membranes like PVC or TPO. The catch: your permit application and plans must specify WHICH method and provide product documentation (data sheet, installation instructions). Medina examiners frequently reject submittals that say 'waterproofed per code' or 'tile surround' without specifying the waterproofing layer beneath. If you list 'Schlüter KERDI,' you must also show that the substrate is compatible (e.g., cement board on studs with blocking, not drywall alone), that seams are sealed, and that the membrane extends 12 inches up the wall above the tub rim or 60 inches above the shower floor.

Common violations in Medina remodel submittals: (1) tile on drywall without a membrane — drywall wicks moisture and eventually rots; it's not code-compliant for a wet area. (2) Cement board without a membrane — cement board is just a substrate; it does not waterproof by itself. (3) 'Standard' mortar-set tile without addressing the substrate — standard thinset mortar over drywall is not waterproof. (4) Mixing waterproofing systems — e.g., KERDI membrane on one wall, liquid-applied on another, without clearly showing seams and overlaps. The examiner will ask for clarification, and you'll lose a week to resubmission.

For a shower conversion (like Scenario B), waterproofing complexity increases. A walk-in shower requires a sloped base (minimum 1/4 inch per foot slope to the drain), secondary containment (a drain pan beneath the base to catch any water that bypasses the primary drain), and a complete membrane envelope. If you're using a pre-fabricated shower pan (fiberglass, acrylic, or solid surface), the plan must specify the product name and model. If you're building a custom pan (mud base + membrane + tile), the plan must show the slope, the membrane routing (where it starts, how high it goes, seam details), and the secondary drain. Medina does not allow 'we'll figure it out on-site' — the examiner wants to see it on the plan before the contractor arrives.

Exhaust ventilation and duct routing in Medina bathroom remodels: IRC M1505 specifics and Medina's plan requirements

IRC M1505 requires that bathrooms in Medina (and all of Ohio) have mechanical ventilation: bathrooms with windows are exempt if the operable window area is at least 5% of floor area, but permanent mechanical ventilation is almost always installed for comfort and code compliance. The exhaust fan duct must exhaust outdoors (not into an attic, crawl space, or recirculate into the home), must be sealed with tape or mastic (not just shoved loosely into a wall cavity), and must be rigid or flex duct rated for the application (UL 181 flex duct, not dryer vent hose). The duct diameter depends on the fan CFM (cubic feet per minute): a typical bathroom fan is 80-110 CFM, requiring a 4-inch or 6-inch duct; a larger bathroom or wet area may require a higher-CFM fan and thus a larger duct. Medina's requirement is that the duct routing and termination method be shown explicitly on the mechanical plan: 'Duct exits through soffit' or 'Duct exits through roof with flashing' or 'Duct exits through wall with damper' — not just 'ductwork per code.'

Common Medina rejections on exhaust duct plans: (1) no termination detail shown (where does the duct actually exit the home?); (2) duct routed through an attic without sealing or terminating outdoors ('we'll just vent into the attic' is never acceptable); (3) fan CFM and duct diameter mismatch (e.g., 150-CFM fan on a 4-inch duct, which is undersized); (4) damper type not specified (a gravity damper or motorized damper is required to prevent back-drafting); (5) duct run length not verified (some examiners flag runs longer than 25 feet, which can reduce fan effectiveness). If you're replacing an existing exhaust fan in place (same location, same duct), you may be able to reference the existing duct routing in your permit application, but if the duct is new or being rerouted, you must show it on the plan.
