The Short Answer
A full bathroom remodel requires a permit if you're relocating fixtures, adding circuits, installing new exhaust ventilation, converting tub to shower, or moving walls. Surface-only work—tile, vanity, or faucet replacement in the same location—is exempt.
Richmond, Kentucky operates under the 2018 International Building Code as adopted by the state, but the City of Richmond Building Department applies its own plan-review process and fee schedule that differs from neighboring cities like Lexington or Berea. Richmond requires a single consolidated bathroom permit rather than separate plumbing and electrical permits, which can save you 1–2 weeks of sequential reviews if you're doing coordinated work. The city's frost depth is 24 inches, which means any new or relocated drain line must drop below that mark before horizontal runs—a critical detail that often causes re-submittals in winter projects. Richmond's permit portal requires either in-person filing at City Hall or email submission of plans, and the city's typical review window is 5–7 business days for standard bathroom remodels (longer if walls are moving or the home was built before 1978, which triggers lead-paint disclosures). Your biggest local surprise: Richmond requires pressure-balanced or thermostatic mixing valves on ALL new shower valves, per the state's adoption of IRC R607.2, and the city's inspectors will reject permits without the valve manufacturer's spec sheet attached to the plumbing plan.

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

Richmond, Kentucky bathroom remodel permits — the key details

Richmond requires a permit for ANY bathroom remodel that involves fixture relocation, new plumbing lines, electrical circuit additions, exhaust-fan installation, or wall removal—basically anything beyond cosmetic swap-outs. The City of Richmond Building Department's single consolidated permit (rather than separate plumbing and electrical permits) covers all trades under one review, which speeds up the approval process compared to Lexington's system. The permit application requires: (1) a site plan showing bathroom location and any wall changes, (2) a plumbing plan with fixture locations, trap-arm lengths, and drain-line routing, (3) an electrical plan showing new circuits, GFCI/AFCI protection, and any vent-fan outlet, and (4) a plumbing specification sheet listing valve models, drain-fitting types, and waterproofing assembly details. Per IRC P2706 and Kentucky adoption of the state plumbing code, all horizontal drain runs must be pitched at 1/4 inch per foot, trap arms cannot exceed 6 feet, and the slope must be consistent—Richmond inspectors often cite incorrect pitch or trap-arm length as the #1 rejection reason. The city's frost depth is 24 inches, so any new drain line that penetrates the slab or crawlspace must either stay above grade or be buried below that threshold; failing to show this detail in your plan will trigger a revision request.

Electrical work in bathroom remodels is tightly regulated under IRC E3902 and the National Electrical Code adopted by Kentucky. All new circuits serving the bathroom must have GFCI protection (ground-fault circuit interrupter); if you're adding an exhaust fan on an existing circuit, that circuit must also be upgraded to GFCI. Any new receptacles, light fixtures, or heated floors require GFCI. Notably, Richmond also enforces AFCI (arc-fault circuit interrupter) protection on bedroom circuits—a common miss when homeowners forget that a master bath shares a wall with the bedroom. You cannot self-wire a new circuit; Richmond does not have an owner-builder electrical exemption (unlike some rural Kentucky counties), so you must hire a licensed electrician. The electrical plan must show: (1) all new circuit numbers and breaker positions, (2) GFCI/AFCI protection details, (3) exhaust-fan outlet location and wattage, and (4) any heated-floor or radiant-mirror specs. The city's inspectors will request the electrician's license number on all submittals, and they inspect rough-in before drywall is hung.

Exhaust ventilation is mandatory per IRC M1505 and must be sized by the bathroom's square footage: less than 100 sq ft requires minimum 50 CFM (cubic feet per minute) of continuous ventilation; 100+ sq ft requires 5 CFM per square foot. The duct cannot be insulated (condensation trap), must be rigid or semi-rigid (no flexible duct except the last 2 feet to the hood), and must terminate to the exterior—NOT into an attic or soffit. Richmond's climate (4A) means summer humidity is high, and the city's inspectors are strict about duct termination; they will reject plans that show ducting into a vented soffit or attic. The exhaust fan must be controlled by a manual switch or humidistat (auto-on if humidity exceeds ~60%). If the bathroom has a tub or shower, the exhaust fan plan must show the rough-in location and ductwork routing on the plumbing plan; this avoids conflicts with the drain-line slope. Many homeowners forget that the duct must be graded away from the hood (downhill slope back to the bathroom) to prevent condensate from dripping into the fan motor. Richmond's inspectors will ask for a photo of the duct termination at final inspection, so plan for a roofer to cut the soffit vent and seal it properly.

Waterproofing for new shower or tub enclosures is governed by IRC R702.4.2 and is non-negotiable in Richmond. If you're converting a tub to a shower or installing a new tub/shower, the entire shower enclosure (floor, walls, and ceiling if applicable) must have a water-resistant barrier: either cement board (minimum 1/2 inch) with a polyethylene or rubberized membrane, or a pre-fabricated waterproofing assembly (like Schluter, Wedi, or DuRock). The waterproofing plan must specify the exact product (manufacturer, thickness, and coverage area), and the inspector will request the product data sheet during plan review. Tile alone is NOT waterproofing; it's decorative and can fail at grout lines, allowing water into the framing (leading to mold and structural rot). If you're keeping an existing tub in place and only replacing the faucet, waterproofing is NOT required (exempt). The permit application must include a waterproofing detail drawing showing: (1) the membrane location (floor, walls, curb), (2) membrane overlap at seams (minimum 6 inches), (3) corner and penetration sealing, and (4) the tile layout and grout spacing. Many Richmond permitting rejections stem from vague waterproofing details ('TBD' or 'standard tile install') that don't meet code. The city's inspectors will perform a rough inspection after the membrane is installed but before tile is laid, to verify seams, corners, and penetrations.

Richmond allows owner-builder permits for owner-occupied bathrooms, but only for the permit itself—you cannot perform licensed work (plumbing, electrical, exhaust ducting). You can do: demolition, framing, drywall, taping, insulation, tile, and finishing. The plumbing, electrical, and HVAC must be performed by licensed contractors, and their work is signed off by them on the permit. If you attempt any plumbing or electrical yourself and the inspector discovers it, the permit is void, the work must be removed, and you'll face a $500+ fine plus the cost to hire a licensed contractor to redo it. The permit fees for a full bathroom remodel in Richmond typically range from $250 to $800, depending on the project's estimated valuation (typically 1.5–2% of labor + materials cost). The city charges a separate inspection fee (usually $50–$100 per inspection visit) for rough plumbing, rough electrical, framing/waterproofing, and final. Timeline: plan review is 5–7 business days; construction typically takes 2–4 weeks; final inspection is usually same-day or next-day if no deficiencies. If the home was built before 1978, the permit application must include a lead-paint disclosure (EPA form), and any demolition work requires lead-safe work practices (containment, HEPA filter, certified contractor), adding $1,500–$3,000 to the cost.

Three Richmond bathroom remodel (full) scenarios

Scenario A
Master bath in 1995 ranch home: relocating toilet and vanity, new shower valve, new exhaust fan—no wall changes, same-location tub.
You're moving the toilet 8 feet to the opposite wall and the vanity sink 4 feet perpendicular; the existing tub stays in place but gets a new pressure-balanced mixing valve and tile surround. This is a common scenario in Richmond's post-WWII neighborhoods. The new drain for the relocated toilet must be sized at 3 inches (IRC P2906 minimum), sloped 1/4 inch per foot toward the main stack, and the trap arm cannot exceed 6 feet from the P-trap to the vent. Richmond's 24-inch frost depth means the drain line must either loop above grade (crawlspace or slab) or be buried below 24 inches if it exits the home. The vanity drain (1.25 inch) can share a wet vent with the toilet if the vent is sized correctly, which the plumbing plan must show. A new exhaust fan on a new 15-amp circuit (dedicated to the fan) requires GFCI protection; the electrician must run Romex or conduit from the breaker panel through the attic to the hood location and terminate the duct through the soffit (minimum 12 inches from the roof, angled away from the home). The toilet relocation triggers a rough plumbing inspection before walls are closed; the vanity and fan trigger electrical rough-in inspection. The tile surround on the tub requires a waterproofing membrane even though the tub is existing—you're installing new tile, so IRC R702.4.2 applies. Estimated permit cost: $350–$500. Plan review: 5–7 days. Inspections: rough plumbing, rough electrical, framing/waterproofing (if drywall is new), final. Timeline: 2–3 weeks of construction after permit approval.
Permit required | Fixture relocation triggers plan review | Pressure-balanced valve required | Exhaust fan duct must reach exterior | Waterproofing required for new tile | $350–$500 permit + inspection fees | Rough plumbing, rough electrical, final inspections
Scenario B
Powder room in 1955 cottage: converting standard tub to walk-in shower with bench, changing wall layout, pre-1978 construction.
This project triggers Richmond's most stringent requirements because it combines tub-to-shower conversion (new waterproofing assembly), wall relocation (structural review), and lead-paint disclosure (pre-1978 home). The tub-to-shower conversion requires you to: (1) remove the existing tub and install a new drain pan or linear drain at the shower floor (sloped toward the drain, minimum 1/4 inch per foot), (2) install a waterproofing membrane covering the entire shower enclosure (floor, walls to 36 inches, curb, corners), and (3) specify the exact membrane system (cement board + polyethylene, or Wedi board, or Schluter, with product data sheets attached to the plan). The walk-in shower bench is considered an extension of the shower enclosure, so it must be covered by the waterproofing membrane as well. The wall relocation (if you're removing a half-wall to open the room) requires structural review; the plumber must verify that the toilet vent and drain stack are not affected by the wall removal. If the drain stack is moved, that's a plumbing plan revision. The pre-1978 lead-paint rule requires: (1) an EPA RRP (Renovation, Repair, and Painting) disclosure form signed at permit pickup, (2) lead-safe work practices (HEPA filter vacuum, containment barriers, waste disposal in sealed bags), and (3) a certified lead-safe contractor or an owner-builder who has passed the EPA RRP test (takes 1 day, costs ~$400). Lead-safe work adds $2,000–$4,000 to the project. Richmond's inspector will visit during the rough-in phase (after walls are framed and closed, before tile) to verify the waterproofing membrane seams, corners, and penetrations. If the wall relocation involves structural changes (removing bearing walls or cutting joists), a structural engineer's stamp is required on the framing plan, adding $500–$1,000. Estimated permit cost: $600–$800 (higher due to structural review and lead-paint complexity). Plan review: 7–10 business days. Inspections: rough plumbing, framing (if structural), waterproofing (before tile), final. Timeline: 3–4 weeks of construction.
Permit required | Tub-to-shower conversion = new waterproofing assembly | Wall relocation requires structural review | Pre-1978 lead-paint EPA RRP disclosure mandatory | Lead-safe work practices add $2,000–$4,000 | Waterproofing membrane must cover entire enclosure | $600–$800 permit + inspection fees | 7–10 day plan review
Scenario C
Small guest bath in 2005 home: faucet replacement, tile backsplash above vanity, new mirror—no fixture moves, no electrical changes.
This is surface-only work and does NOT require a permit. You're replacing the existing faucet with a new one in the same location (no drain-line changes), installing decorative tile on the wall above the existing vanity (not a waterproofing assembly; it's cosmetic), and hanging a new mirror. No plumbing fixtures are relocated, no electrical circuits are added, no walls are modified, and no structural changes occur. The faucet swap is a straightforward fixture replacement; the supply lines are already in place and do not need to be re-routed. Tile that is glued to existing drywall (not part of a shower or tub enclosure) does not trigger waterproofing code, so you do not need IRC R702.4.2 review. Richmond Building Department explicitly exempts fixture-in-place replacements from permitting, so you can buy your faucet and tile at a big-box store, hire a plumber for a few hours, and proceed without paperwork. However, if you accidentally bump a supply line or discover old galvanized steel plumbing that needs replacement, you're now in the weeds—you have to stop, pull a permit retroactively, and hire a licensed plumber to certify the new line. Best practice: have your plumber verify the supply lines are copper or PEX and in good condition before you commit to the cosmetic-only plan. If you're replacing the toilet in the same location (bolts are in the same holes, same floor flange), that's also exempt. Total cost: $500–$1,500 for faucet, tile, mirror, and labor—no permit fees. No inspections, no plan review, no timeline delays.
No permit required | Fixture replacement in place is exempt | Cosmetic tile (non-shower) does not trigger waterproofing code | $500–$1,500 total cost (no permit fees) | No inspections or plan review | Can proceed immediately

Waterproofing assemblies: why Richmond inspectors reject plans and how to fix it

Richmond's most common permit rejection for bathroom remodels is a waterproofing detail that says 'standard tile install' or 'cement board + grout.' This fails because IRC R702.4.2 requires a COMPLETE water-resistant assembly, not just tile. The city's inspectors are trained to catch this because limestone-based soil (Richmond sits on karst geology with subsurface water movement) makes moisture intrusion especially damaging; if water gets into framing, it promotes mold and collapses structural integrity faster than in non-karst areas.

The correct approach is to specify the exact membrane system by product name and manufacturer. Option 1: Cement board (1/2 inch minimum) + polyethylene sheet (4-mil minimum) stapled under the cement board, with seams overlapped 6 inches and taped with cement-board tape. Option 2: Pre-fabricated waterproofing board (Wedi, Schluter, Durock, etc.) installed per manufacturer specs, with all seams sealed. Option 3: Liquid membrane (RedGard, Hydro Ban) applied per product data sheet, typically 2 coats on cement board. Your plumbing plan must include a detail drawing (8.5x11 cross-section) showing the membrane location, overlap, corner sealing, and penetration (drain, overflow) treatment. Attach the product data sheet (1–2 pages from the manufacturer) to the permit application.

Richmond's inspectors perform a rough waterproofing inspection after the membrane is installed but BEFORE tile is laid. They will check: (1) membrane is continuous across the floor and walls, (2) seams are overlapped 6 inches minimum, (3) corners and curbs are sealed, (4) the drain penetration is sealed with a waterproofing collar, and (5) the membrane is stapled or fastened per product specs. If you skip this step and tile over a bad membrane, you will be cited and forced to remove tile, fix the membrane, and re-tile at your cost. This adds 1–2 weeks and $2,000–$5,000 to the project.

Lead-paint disclosure and owner-builder limits in Richmond (pre-1978 homes)

Any bathroom remodel in a Richmond home built before 1978 requires an EPA RRP (Renovation, Repair, and Painting) disclosure and lead-safe work practices. This is a federal rule, not just a city rule, but Richmond's building inspectors enforce it at permit time. You must provide a signed EPA RRP form (available free from the EPA website) at permit pickup; failure to provide it voids the permit. If you're an owner-builder (not a licensed contractor), you have two options: (1) hire a certified lead-safe contractor to perform all demolition and renovation work, or (2) obtain your own EPA RRP certification by taking a 1-day course (offered by approved training providers in Lexington and Louisville, cost ~$400). The certification is valid for 3 years and allows you to oversee lead-safe work practices.

If you choose option 2 (owner-builder with certification), you must personally supervise all work and follow these practices: (1) contain the work area with plastic sheeting and duct tape (no dust leaves the room), (2) use a HEPA filter vacuum (standard shop vacs are not HEPA-rated and spread lead dust), (3) wet-wipe all work surfaces daily, (4) dispose of all waste in sealed bags labeled 'lead waste,' and (5) keep the work area off-limits to children and pregnant women. Violations are federal crimes, not just code violations, with fines up to $37,500 per day. If Richmond's inspector observes lead dust or improper containment during inspections, the permit is immediately suspended and referred to the EPA. Most homeowners hire a certified lead-safe contractor to avoid this risk; costs are $2,000–$4,000 for a full bath demolition and renovation. If the home is pre-1978 and you attempt ANY demolition without the EPA RRP form, you are automatically in violation and cannot pull a permit to fix it retroactively.

Owner-builder limits in Richmond are specific: you can perform demolition, framing, drywall, insulation, taping, tile, and finishing. You CANNOT perform plumbing, electrical, HVAC, or any licensed trade. If an inspector discovers unlicensed work, the permit is voided, the work must be torn out and re-done by a licensed contractor, and you face a fine of $500–$1,000 plus the contractor's re-do cost. Some homeowners think they can 'get away with' running their own electrical outlet or rerouting a drain; Richmond inspectors are thorough (they test GFCI outlets, trace drains, and pull rough-in photos), so this strategy almost always fails.

Common questions

Can I get a bathroom permit in Richmond if I'm the homeowner but I'm hiring all contractors?

Yes. Richmond allows owner-builder permits for owner-occupied homes, and you can hire licensed plumbers, electricians, and other contractors to do the work. The permit will list each contractor's license number, and they sign off on their portions of the work. You do not need to pull a separate permit for each trade; the single consolidated bathroom permit covers plumbing, electrical, and HVAC. You must be present at inspections (rough plumbing, rough electrical, final) to allow access.

How long does plan review take for a bathroom remodel in Richmond?

Standard bathroom remodels (fixture relocation, new exhaust fan, same-location tub) typically take 5–7 business days for plan review. More complex projects (wall relocation, tub-to-shower conversion, pre-1978 homes with lead-paint issues) take 7–10 business days. If the plan is incomplete (missing waterproofing detail, GFCI specs, or duct termination), Richmond will issue a revision request, adding 3–5 days. You can reduce review time by submitting a complete, detailed plan (not sketches) with product data sheets and a waterproofing assembly detail drawing.

Do I need a permit to replace my bathroom faucet or toilet in Richmond?

No. Replacing a faucet or toilet in the same location (same supply lines, same drain flange) does not require a permit in Richmond. This is considered a fixture-replacement exemption. However, if you discover the supply lines are galvanized steel or corroded during the replacement, you must notify a plumber and pull a permit to upgrade the lines; this turns it into a permittable project.

What is the pressure-balanced valve requirement I keep hearing about for Richmond?

Richmond enforces IRC R607.2 (and Kentucky's adoption of the state plumbing code) requiring that all NEW shower and tub valves be pressure-balanced or thermostatic mixing valves. These valves prevent scalding by maintaining constant water temperature even if someone flushes a toilet or uses another fixture simultaneously. You must specify the exact valve model on your plumbing plan and attach the manufacturer's spec sheet to the permit. Approved brands include Moen Posi-Temp, Delta MultiChoice, Kohler Forte, and others; check the spec sheet to confirm 'pressure-balanced' or 'thermostatic' is listed. Older manual (non-balanced) valves are not compliant and will be cited at inspection.

My bathroom sits over a crawlspace. Do I need to worry about the frost depth when installing a new drain?

Yes. Richmond's frost depth is 24 inches, and any new drain line that exits the crawlspace must either stay above grade (routed through the rim band and exiting above ground) or be buried below 24 inches. If you're relocating the drain to a new location in the crawlspace, the line must drop below 24 inches before running horizontal toward the main stack. Your plumbing plan must show the elevation and depth of the drain line at all key points (toilet trap, main stack connection). If you skip this detail, the inspector will request a revision or cite you during rough plumbing inspection.

Can I install an exhaust fan on an existing bathroom circuit, or does it need its own circuit?

It depends. If the existing circuit is on a standard breaker and serves other loads (lights, outlets), the circuit must be upgraded to GFCI protection when you add the fan. A dedicated 15-amp or 20-amp circuit for the fan alone is typically the safer approach and avoids nuisance GFCI trips from other devices. Richmond's electrical inspector will ask on the rough-in visit; either approach is code-compliant as long as GFCI is in place and the fan is properly grounded. Your electrician will make this call when sizing the circuit and pulling the permit.

What happens at the rough plumbing, rough electrical, and final inspections for a bathroom remodel?

Rough plumbing (before walls are closed): inspector verifies drain-line pitch, trap-arm length, vent routing, and fixture locations. Rough electrical (before drywall): inspector tests GFCI outlets, verifies circuit paths, and checks exhaust-fan ductwork rough-in. Waterproofing (if new tile/shower): inspector checks membrane seams, corners, and penetration seals before tile is laid. Final inspection (after all work): inspector verifies all fixtures are installed, tile is complete, GFCI outlets are live, and exhaust fan is ducted to exterior. If deficiencies are found, you receive a list and must schedule a re-inspection after corrections (typically $50–$100 fee per re-visit). Most projects pass final on the first try if the rough inspections went smoothly.

Does Richmond have any special requirements for master bathrooms vs. powder rooms?

No. Richmond applies the same code rules to all bathroom sizes. However, smaller bathrooms (powder rooms, half-baths) have lower ventilation CFM requirements (50 CFM for <100 sq ft) and may not have a tub/shower, which simplifies waterproofing. Larger master bathrooms (>100 sq ft, double sinks, soaking tub, separate shower) require higher ventilation (5 CFM per sq ft), GFCI on all receptacles, and careful waterproofing planning if the shower and tub are in separate enclosures. The plumbing plan must show the venting strategy for dual drains (shared vent vs. separate vents).

If my home was built in 1977, do I automatically need lead-paint remediation?

Yes, if you're performing any renovation (including demolition, tile removal, or framing). Homes built before 1978 are presumed to have lead-based paint under EPA rules. You must provide a signed EPA RRP disclosure form at permit pickup. All demolition and renovation work must follow lead-safe practices (HEPA vacuums, containment, wet-wiping, sealed waste disposal). You can either hire a certified lead-safe contractor (recommended) or obtain your own EPA RRP certification by taking a 1-day course. Pre-1978 homes add $2,000–$4,000 to the project cost but are non-negotiable for permitting.

How much does a bathroom remodel permit cost in Richmond?

A standard bathroom permit costs $250–$800 depending on project valuation (typically 1.5–2% of estimated labor + materials cost). Inspection fees are usually $50–$100 per visit (rough plumbing, rough electrical, waterproofing, final = 4 inspections average). Total permit + inspection fees: $350–$1,000. Projects with wall relocation, structural review, or pre-1978 lead-paint work cost more ($600–$1,200) due to extended plan review. Contact Richmond Building Department to request a fee estimate based on your project scope before applying.
