Bathroom Remodel Permit in Morgantown, WV (2026)

Research by DoINeedAPermit Research Team · Updated May 2026

The Short Answer

If you're moving fixtures, adding electrical circuits, installing a new exhaust fan, converting tub to shower, or moving walls, you need a permit from the City of Morgantown Building Department. Surface-only work (tile, vanity, faucet swap in place) is exempt.

Morgantown adopts the 2015 International Residential Code (IRC) with West Virginia amendments, and the city requires permits for any bathroom work that changes plumbing or electrical systems, not just cosmetic swaps. What sets Morgantown apart from surrounding municipalities is its strict enforcement of exhaust fan ducting termination — the city inspectors require proof that exhaust duct runs to the exterior (not into the attic), which is often missed in owner-builder projects in the region. Additionally, Morgantown's 30-inch frost depth means any plumbing penetrations below-grade must account for freeze risk, and the city's plan review typically takes 2-3 weeks for full bathroom remodels. The Building Department accepts online submissions via their permit portal, but inspections are scheduled in-person. If your home was built before 1978, lead-paint disclosure and safe-work practices are mandatory before any demolition begins.

What happens if you skip the permit (and you needed one)

Stop-work orders and fines: Morgantown Building Department can issue a stop-work notice and fine of $100–$500 per day of unpermitted work once discovered, plus you'll owe back permit fees (typically $300–$800 for a full remodel).
Insurance and resale issues: Your homeowner's insurance may deny claims related to unpermitted work; buyers' lenders will flag the unpermitted remodel on title search and may refuse to finance, killing your sale.
Lender refinance block: If you ever apply for a refinance or home equity line, the lender's title search will reveal unpermitted work, and you'll be forced to either permit and inspect retroactively (expensive and risky) or accept a lower appraisal.
GFCI/electrical safety liability: Unpermitted electrical work (especially GFCI outlets in bathrooms, required by NEC 210.8) can void your insurance in case of shock or fire, exposing you to personal liability claims.

Morgantown bathroom remodel permits — the key details

Morgantown Building Department enforces the 2015 IRC with West Virginia amendments, and a full bathroom remodel triggers permits if ANY of these apply: you're relocating a toilet, sink, or shower/tub; you're adding a new electrical circuit or outlet; you're installing a new exhaust fan; you're converting a tub to a shower or vice versa; or you're moving, removing, or rebuilding walls. The city does NOT require a permit if you're swapping a faucet, replacing a vanity in the same location, re-tiling existing walls, or replacing a toilet in place with the same connection. This distinction matters because many homeowners assume 'bathroom remodel' always needs a permit — it doesn't. The key question is: are you changing plumbing routing, adding electrical load, or altering the room's structure? If yes, file. If you're only cosmetic, you're exempt. However, if you're unsure, it's cheaper to call the Building Department ($304–$826-7410, roughly; verify the number directly with city hall) and ask than to guess and face a stop-work order mid-project.

Exhaust fan ventilation is one of the most commonly cited deficiencies in Morgantown permits. IRC M1505.1 requires bathroom exhaust fans to be ducted directly to the exterior or attic, with no damper that can trap moisture in the duct itself (a common DIY mistake). Morgantown inspectors verify at rough-in that the duct terminates outside the building envelope and that the duct diameter matches the fan CFM rating (typically 50-100 CFM for a bathroom, 150 CFM if there's a tub and toilet). Many homeowners run flexible aluminum duct into the attic 'for now' thinking they'll finish it later — the inspector will flag this and require a re-do before drywall goes up. If you're adding a new exhaust fan, expect a rough-in inspection before drywall. If you're replacing an existing fan in place, you're often exempt if the duct routing doesn't change, but confirm with the Building Department before you demo the old one.

Plumbing fixture relocation requires a rough plumbing inspection, and Morgantown inspectors pay close attention to trap-arm length and slope. Per IRC P2706, the distance from a fixture trap to the vent stack cannot exceed 3.5 feet for a toilet (or 6 feet for other fixtures), and the drain slope must be 1/4 inch per foot toward the stack. If you're moving a toilet from one wall to an adjacent wall, the new vent arm may violate these limits, and you'll need to re-route the stack — an expensive change that a permit review catches early, but a skipped permit doesn't. Similarly, tub and shower drain pans must slope to the drain, and any new tub-to-shower conversion requires a waterproofing assembly (cement board + membrane, or equivalent) that the inspector must see at rough-in before drywall. Shifting fixtures also means new penetrations through the subfloor, which must be sealed to prevent below-grade moisture intrusion (critical in Morgantown's freeze-thaw climate with 30-inch frost depth).

Electrical work in bathrooms is heavily regulated. NEC 210.8 requires all outlets within 6 feet of a sink to be GFCI-protected (ground-fault circuit interrupter), and if you're adding outlets or a new circuit for a heated towel rack, ventilation fan, or lighting, those must be GFCI outlets or fed through a GFCI breaker. Morgantown's electrical rough-in inspection verifies that all GFCI receptacles are present, correctly wired, and labeled. Many homeowners install standard outlets and think they can add a plug-in GFCI later — don't assume this; the permit requires it specified on the electrical plan upfront. If your bathroom has an older panel with limited capacity, adding a new 20-amp circuit for heated elements may require panel upgrade, which adds $800–$1,500. The permit review will catch this before you're mid-construction.

Water damage and lead-paint rules are Morgantown-specific practical concerns. Any bathroom remodel involving wall removal or demolition in a home built before 1978 requires lead-safe work practices (containment, HEPA vacuuming, disposal certification). The City of Morgantown enforces EPA lead-renovation rules, and if you're a contractor (not owner-builder), you must be EPA-certified; even as an owner-builder, you must follow containment. Regarding water damage, Morgantown's rocky, coal-bearing mountain soil and 30-inch frost depth mean that any plumbing work below the subfloor is at risk of freezing if not properly trapped and insulated. The permit review doesn't explicitly address this, but inspectors will ask about freeze protection if you're relocating drains in unheated spaces. Finally, if you're converting a bathtub to a shower, the new waterproofing assembly (IRC R702.4.2) must extend at least 72 inches above the shower floor on all walls, and the inspector will verify this at rough-in. Skipping the permit means you build the waterproofing assembly without inspection, and if it leaks into the floor below (common in Morgantown's older homes), you've created a costly mold and structural issue that insurance won't cover if the work was unpermitted.

Three Morgantown bathroom remodel (full) scenarios

Scenario A

Master bath cosmetic refresh: new vanity, faucet, and tile (same fixture locations, no plumbing moves, no electrical adds)

You're replacing an existing vanity with a new one in the same footprint, swapping out the faucet (same supply lines), and re-tiling the shower surround and floor. No walls are moving, no exhaust fan is being added or changed, and you're not adding any circuits. This is pure cosmetic work and does NOT require a permit from the City of Morgantown Building Department. You can purchase the vanity, hire a plumber to swap the faucet (or do it yourself if you're comfortable), and hire a tile contractor. No rough-in inspections, no plan review, no permit fee. However, if your vanity is 40+ years old and the supply shutoff valves are seized or corroded, you may need to re-route the supply lines slightly to access new shutoffs — the moment you break the existing routing, you're moving fixtures, which triggers a permit. Similarly, if the new vanity cabinet is wider and requires the drain to be relocated horizontally (even by a few inches), that's a fixture move and you'll need a permit. So the line is: exact location swap, no permit; any routing change, permit required. Many homeowners call the Building Department to confirm before starting tile work, which is smart. Cost: $2,000–$8,000 for vanity, faucet, tile labor, no permit fees.

Scenario B

Moving toilet to opposite wall, new exhaust fan with exterior duct, GFCI circuit added (East Morgantown ranch home)

You're gutting an older ranch-style master bath in East Morgantown (typical 1960s-70s construction with 2x4 walls and a crawlspace). You want to move the toilet from the north wall to the south wall (opposite end of the bathroom), install a new exhaust fan with proper exterior ductwork (the old fan just vents into the attic), and add a dedicated 20-amp GFCI circuit for a heated towel rack. This triggers a full permit: plumbing relocation (toilet move), electrical (new circuit + GFCI), and mechanical (exhaust fan). You'll file a permit application with the City of Morgantown Building Department, providing a floor plan showing the new toilet location, a plumbing schematic showing the new drain and vent routing, an electrical single-line diagram showing the new GFCI circuit and breaker, and a detail of the exhaust fan duct termination (must exit the home, not terminate in the attic or soffit). Plan review takes 2-3 weeks; the reviewer will flag any trap-arm violations (the new vent stack must be within 3.5 feet of the toilet trap, and Morgantown's average ceiling height may require a new vent penetration through the roof, adding cost). Once approved, you'll schedule a rough-in inspection after framing and plumbing/electrical rough-in but before drywall. The inspector verifies trap slope, vent positioning, GFCI outlet installation, and exhaust duct routing. Expect 2-3 inspections (rough plumbing, rough electrical, final). Permit fee: $400–$650 depending on project valuation (typically based on labor + materials estimate). If the plan review flags trap-arm issues, you may need to re-route the stack, adding $600–$1,200 to your project cost. Total timeline: 1-2 weeks for plan review + 1-2 weeks for construction + inspections = 3-4 weeks, plus any revisions.

Scenario C

Tub-to-shower conversion with new waterproofing assembly, wall relocation, owner-builder (downtown Morgantown circa-1920 Victorian)

You own a 1920s Victorian in downtown Morgantown with a vintage claw-foot tub, and you want to convert it to a walk-in shower. You're also removing a non-load-bearing wall between the bathroom and an adjacent closet to enlarge the shower area. The new shower will have a custom waterproofing assembly (cement board + liquid membrane), a new tile surround, a frameless glass enclosure, and a pressure-balanced mixing valve (required per IRC R2803.2 for anti-scald protection). As the owner-builder (not hiring a general contractor), you can pull the permit yourself in Morgantown, though you'll need to contract out framing, plumbing, and tile work (or do it if you're skilled). This is a MAJOR permit because it involves fixture relocation (tub drain), wall removal, and a new waterproofing assembly. You'll file a full permit application with architectural or construction drawings showing the wall removal, framing plan (to prove the wall is non-load-bearing or show proper headers if load-bearing), plumbing schematic, and a waterproofing detail (cross-section of the shower pan showing cement board, membrane, drain pan slope, and drain location). Plan review is 2-3 weeks; the reviewer will likely require a structural engineer's letter confirming the wall removal is safe (cost: $300–$600, not included in permit but required for approval). Once permitted, you'll schedule inspections: framing (before wall removal), plumbing rough-in (drain and vent), drywall (if applicable), and final. The waterproofing assembly is critical: cement board must be installed per manufacturer specs, membrane must overlap the shower pan by at least 6 inches on all walls extending 72 inches above the floor, and the drain pan must slope 1/4 inch per foot toward the drain. Morgantown inspectors will photograph the membrane before tile goes on. If the membrane is missing or incorrectly installed, the inspector will reject the rough inspection and require remediation. Additionally, because the home was built before 1978, you must follow lead-safe work practices during demolition (containment, HEPA vacuum, certified disposal of lead-bearing dust). Permit fee: $500–$800. Lead-safe work training (if required by EPA): $0–$200. Structural engineer letter: $300–$600. Total timeline: 1-2 weeks prep, 2-3 weeks plan review, 3-5 weeks construction with inspections = 6-10 weeks. Total project cost: $8,000–$18,000 depending on tile quality, glass enclosure, and whether you do labor yourself.

Morgantown's freeze-thaw climate and below-grade plumbing risks in bathroom remodels

Morgantown sits in climate zone 5A with a frost depth of 30 inches, meaning any plumbing that penetrates the subfloor or rim joist must be protected from freezing. If you're relocating a toilet, sink, or shower drain to a new location, the new vent pipe and trap arm must be insulated or routed through conditioned space; if routed through an unheated crawlspace or basement, the trap can freeze in winter, blocking drainage and potentially cracking the trap body. Morgantown's permit review doesn't explicitly call this out, but inspectors will ask about freeze protection if they see below-grade plumbing in an unheated area.

The city's coal-bearing, rocky mountain soil also affects drainage: settling is common in older homes, which can throw trap slope out of spec (IRC P2705 requires 1/4 inch per foot, or 0.4% slope). If you're relocating a drain and discover the subfloor has settled, you may need to sister-joist or re-slope the entire line, a cost that a permit review helps surface early. Additionally, groundwater and seepage are risks in Morgantown's older basements; if your bathroom is in a below-grade space or partial basement, any floor drain work must account for potential water intrusion, and the inspection will verify that the drain pan slopes correctly to prevent pooling.

For tub-to-shower conversions specifically, the new waterproofing assembly must account for Morgantown's moisture climate. Cement board + liquid membrane is the most common assembly; it must extend 72 inches above the floor on all four walls and 6 inches up the curb on the entry side. If the membrane fails (puncture, improper overlap, or installer error), water leaks into the floor and subfloor, and in Morgantown's damp climate, mold colonizes quickly. The permit review and rough-in inspection catch these issues before drywall or finish tile. Skipping the permit means you install the membrane without inspection, and if it leaks, you're facing $5,000–$15,000 in remediation (drywall removal, subfloor replacement, mold remediation) that your homeowner's insurance will deny because the work was unpermitted.

Morgantown's GFCI and AFCI requirements for bathroom electrical work

NEC 210.8 (adopted by West Virginia and enforced in Morgantown) requires all outlets within 6 feet of a sink, tub, or shower to be GFCI-protected. This includes the main vanity outlet, any outlets on adjacent walls, and any outlets that might be splashed during use. If you're adding a new outlet for a heated towel rack, it must be GFCI. Many homeowners think they can install a standard outlet and add a plug-in GFCI adapter later — this is non-compliant. The permit requires GFCI receptacles or a GFCI breaker specified on the electrical plan, and the rough-in inspection verifies that all GFCI outlets are present and correctly wired before drywall.

Additionally, if your bathroom is in a bedroom or if the bathroom is part of a bedroom suite (master bath en-suite), NEC 210.12 may require AFCI protection (arc-fault circuit interrupter) on all outlets. Morgantown inspectors verify this on the electrical plan and at rough-in. If you're adding a new circuit and fail to specify AFCI where required, the permit review will kick it back for revision, delaying your project by 1-2 weeks. If you skip the permit and install non-compliant outlets, the inspector (if called by a neighbor or during a later inspection) will cite the work as non-permitted and non-compliant, and you'll face a fine plus the cost of remediation.

For any bathroom electrical work, the permit application must include a single-line diagram showing the new circuit, breaker size and type (15-amp or 20-amp, GFCI or AFCI), and outlet locations. If you're upgrading from a 100-amp to a 200-amp service to accommodate new circuits (common in older Morgantown homes), that's a separate service upgrade permit and inspection, adding $1,500–$3,000 to your project. The electrical plan review catches this before you start wiring, avoiding mid-project surprises.

Common questions

Do I need a permit to replace my toilet in the same location?

No. If you're swapping out an old toilet for a new one in the same spot with the same supply and drain connections, it's a cosmetic replacement and does NOT require a permit. However, if you're relocating the toilet to a new wall or moving the supply/drain lines even slightly, you need a permit. When in doubt, call the Building Department to confirm your specific situation.

What if I'm just replacing my bathroom vanity and faucet?

Replacing a vanity and faucet in the same location, using the existing supply lines and drain, is exempt from permitting. If the new vanity is significantly larger or smaller and requires you to re-route the supply or drain lines, that's a fixture relocation and requires a permit. The key is: are you changing the plumbing routing? If no, no permit. If yes, permit required.

Do I need a permit to add a new exhaust fan in my bathroom?

Yes. Any new exhaust fan installation or replacement with a different duct routing requires a permit. The permit verifies that the duct runs to the exterior (not the attic, which traps moisture), is properly sized for the fan CFM, and is sealed at all joints. This is one of the most commonly cited deficiencies in Morgantown permits because homeowners often vent fans into attic spaces, which the inspector will reject. Budget $200–$400 for the permit and plan review.

Can I convert my bathtub to a shower without a permit?

No. Converting a tub to a shower changes the waterproofing assembly and requires a new waterproofing design (typically cement board + liquid membrane extending 72 inches up the walls). The permit review and rough-in inspection verify that the waterproofing is correctly installed before tile and finish. This is a significant water-damage risk if done wrong, and Morgantown requires a permit to catch errors early.

What does a bathroom rough-in inspection include?

The rough-in inspection happens after framing and plumbing/electrical work but before drywall. The inspector verifies: toilet trap location and vent arm distance (within 3.5 feet for toilets), drain slope (1/4 inch per foot), exhaust fan duct routing and termination, GFCI outlet wiring, supply line placement, and (for tub-to-shower conversions) waterproofing membrane installation. If something is out of spec, the inspector will flag it and require remediation before you proceed to drywall.

How much does a bathroom remodel permit cost in Morgantown?

Permit fees in Morgantown typically range from $200–$800 depending on the project valuation (labor + materials estimate). A cosmetic refresh (vanity, tile, faucet) is exempt. A fixture relocation with new electrical is $300–$500. A full gut with wall removal and tub-to-shower conversion is $500–$800. Plan review typically takes 2-3 weeks. Call the Building Department for an exact fee quote once you have a project scope and estimate.

Do I need a structural engineer's letter if I'm removing a bathroom wall?

If the wall is non-load-bearing, no. If the wall is load-bearing or you're unsure, yes. The permit review will require clarification. A structural engineer's letter costs $300–$600 and confirms that the wall removal is safe and that proper headers or beams are installed. This is mandatory before the framing inspection is approved. Do not remove a wall without confirming its status with the Building Department first.

What if my home was built before 1978 and I'm doing a bathroom remodel?

You must follow EPA lead-safe work practices for any demolition (wall removal, tile demo, fixture removal). This includes containment (plastic sheeting), HEPA vacuuming, and certified disposal of lead-bearing dust. If you're the owner-builder, you must follow these practices or hire a lead-certified contractor. The permit will note this requirement, and inspectors may verify containment during rough-in. Non-compliance can result in fines and liability.

Can I pull a bathroom permit as an owner-builder in Morgantown, or do I need a licensed contractor?

Yes, Morgantown allows owner-builders to pull permits for owner-occupied homes. You can file the permit yourself and schedule inspections. However, you may need to contract out specific trades (plumbing, electrical, HVAC) depending on the scope and your skill level. Check with the Building Department about which work you can do yourself and which requires a licensed contractor.

What happens if the permit review finds a problem with my plumbing or electrical plan?

The reviewer will issue a request for modifications (RFI) detailing the issue (e.g., 'trap arm exceeds 3.5 feet — relocate vent stack' or 'GFCI outlet missing on circuit — add GFCI receptacle at location marked'). You'll revise the plan and resubmit; review of revisions typically takes 3-5 business days. Once approved, you can begin construction. This process catches code violations early, before you're mid-project and facing expensive rework.
