Bathroom Remodel Permit in Hopkinsville, KY (2026)

Q: Do I need a permit to replace a toilet in place?

No, if the toilet stays in its current location (same drain hole). Replacing a toilet is surface work: disconnect the water supply, unbolt the old toilet, and install a new one. You do not need a permit. However, if you're moving the toilet even a few feet, or if you're converting from a floor-mounted to a wall-mounted toilet (different drain location), that's a plumbing relocation and requires a permit.

Q: What's the difference between a bathroom remodel permit and a plumbing permit?

They often go together. A general/remodel permit covers the overall project (framing, finishes, inspections). A plumbing permit specifically covers drain/vent/water supply work (fixture relocation, new drains, vent changes). For a bathroom remodel with fixture moves, you'll file both: the general permit and the plumbing permit. Hopkinsville Building Department may issue them as one package or separate, depending on the scope. If you're only moving fixtures, a plumbing-only permit may be sufficient.

Q: Can I do a full bathroom remodel myself, or do I have to hire a contractor?

Hopkinsville allows owner-builders on owner-occupied homes. You can pull the permit in your name and do the work yourself, provided you pass all inspections. However, you must still comply with code (GFCI, waterproofing, exhaust duct slope, etc.). Electrical and plumbing rough work must be inspected before concealment. Many homeowners hire a plumber and electrician but do the demolition, framing, and tile themselves. The permit doesn't care who does the labor; it only cares that the final product is code-compliant.

Q: How long is a bathroom remodel permit valid?

A permit is typically valid for 180 days from the date of issuance. If you don't pull all required inspections within that window, you'll need to renew the permit (usually a small fee, $25-$50). If the project stalls or is abandoned, the permit expires and you'll need to re-apply. The clock also pauses during winter (some jurisdictions don't inspect in harsh weather), so confirm the expiration date with the Building Department when you pick up your permit.

Q: What is a GFCI, and do I really need one in a bathroom?

GFCI stands for Ground Fault Circuit Interrupter — a device that cuts power if it detects a ground fault (electricity flowing where it shouldn't, like through water). It's a shock hazard protection. Kentucky Code Section E3902 requires GFCI protection on all bathroom circuits within 6 feet of a sink, tub, or shower. You can use a GFCI outlet or a GFCI breaker; either works. A GFCI outlet costs $15-$30 and is installed in a standard outlet box. A GFCI breaker costs $50-$100 and replaces the breaker itself. Most homeowners use GFCI outlets in bathrooms. The Building Department will verify GFCI protection on final electrical inspection.

Q: My bathroom is in an older house built before 1978. Do I need to worry about lead paint?

Yes. Kentucky state law (and federal law under the RRP Rule) requires disclosure and caution if the home is pre-1978 and you're disturbing paint during renovation. Removing a tub surround, demo a wall, or sand old painted surfaces triggers the disclosure requirement. You must notify occupants or buyers in writing before disturbing the paint. If you're a homeowner remodeling your own home, the RRP Rule is less strict, but you still must take precautions (wet-sand instead of dry-sand, use HEPA filters, clean up dust). The Building Department doesn't enforce lead-paint rules directly, but they may ask if the home is pre-1978 and what precautions you're taking. A lead-safe contractor has RRP certification; if you're DIY, research EPA RRP practices or hire a certified contractor for the demolition phase.

Q: What happens if I install an exhaust fan duct that vents into my attic instead of outside?

This violates IRC M1505.2 and is a common code violation. Bathroom exhaust venting into the attic causes moisture buildup, leading to mold, rot, and insulation damage. The Building Department will fail the rough inspection and require you to extend the duct to the exterior (through the roof or a wall with a damper vent). Once drywall is up, you'll have to tear it open to re-do the ductwork. The fix costs $400-$800 and delays the project 1-2 weeks. Always vent exhaust fans to the exterior.

Q: How much does a bathroom remodel permit cost in Hopkinsville?

Hopkinsville permit fees for a bathroom remodel typically range from $250 to $500 total, depending on the scope and declared project valuation. A permit-fee calculator uses the estimated construction cost: for a $6,000 remodel, fees are often 1–1.5% of that value (roughly $60-$90), plus a base review fee ($150-$200). If you're adding electrical circuits, add another $100-$150. Plumbing permits are sometimes bundled in the general permit or charged separately ($50-$100). Call the Building Department to confirm the exact fee structure for your project scope; they can give you a pre-application estimate before you file.

Q: Can I change the bathroom layout (move walls, relocate fixtures) without violating code?

Yes, provided you pull a permit and the work meets code. Moving walls, relocating fixtures, and changing the layout all require a permit and inspection. The Building Department will verify that any removed wall is non-load-bearing (or has adequate support if load-bearing), that drain trap arms don't exceed 3 feet, and that vents are properly routed. Many layout changes are totally doable; they just require planning and inspection. If a wall is load-bearing and you want to remove it, you'll need a structural engineer's drawings and a beam installation — that adds cost and time. Have the Building Department pre-review your layout before you start demo.

Q: What is the most common reason a bathroom permit is rejected in Hopkinsville?

Missing waterproofing specification (for shower conversions or new showers). The Building Department asks applicants to specify the waterproofing system (cement board + liquid membrane, pre-fab acrylic pan, Schluter system, etc.), and many homeowners don't have this detail ready. The second most common: exhaust duct vent termination not specified (must go to exterior, not attic, with a damper). The third: GFCI protection not shown on electrical plan. If you submit a detailed, compliant permit application with these three items clearly documented, you'll pass plan review on the first submission.

The Short Answer

A full bathroom remodel in Hopkinsville almost always requires a permit if it involves moving fixtures, adding circuits, installing a new exhaust fan, or touching any walls. Surface-only work (tile, vanity swap in place, faucet replacement) is exempt.

Hopkinsville follows the Kentucky Building Code, which adopts the 2015 International Building Code with state amendments. The City of Hopkinsville Building Department processes permits through its own intake (no online portal as of 2024 — you file in person or by mail at city hall), and this matters for timeline: plan review typically takes 2-4 weeks, not the 1-2 weeks you might see in cities with faster digital systems. Hopkinsville's Building Department is moderately staffed; expect to reach a human for pre-submission questions, which is actually an advantage — they'll flag waterproofing or GFCI issues before you pull the permit. The city sits on karst limestone with bluegrass clay soils, but for an interior remodel that's secondary; what matters is the 24-inch frost depth, which affects any new plumbing vents that penetrate the roof (vent dams or roof flashing must be ICC-compliant). Hopkinsville permits full bathroom remodels under the standard category, and owner-builders are allowed on owner-occupied homes — you don't need a licensed contractor to pull the permit if it's your primary residence, though you must still pass all inspections. The fee structure starts at $150–$300 for plan review, plus a percent-of-valuation fee (typically 1–1.5% of declared valuation) for the construction permit itself.

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

Stop-work order and $250–$500 fine if the Building Department discovers unpermitted work during final sale inspection or neighbor complaint; forced removal or remediation at your expense.
Insurance claim denial: your homeowner's policy can reject a claim for damage (e.g., water intrusion from improper shower waterproofing) if unpermitted work caused it; settlement loss could exceed $20,000.
Title/resale blockage: Kentucky requires disclosure of unpermitted work on sale; buyer's lender will often refuse to close, or require expensive retroactive inspection and remediation ($2,000–$10,000+).
Lien risk: if you hired a contractor and didn't permit, they can file a mechanic's lien for non-payment; even if paid, the unpermitted status complicates lien release and title transfer.

Hopkinsville full bathroom remodel permits — the key details

The single most important rule: any fixture relocation, any new electrical circuit, any exhaust duct, or any wall demolition/relocation triggers a permit in Hopkinsville. The Kentucky Building Code (2015 IBC) Section P2706 governs drainage; Section E3902 mandates GFCI protection on all bathroom circuits; Section M1505 requires exhaust fans to vent to the exterior (not the attic). If you're moving a toilet, sink, or tub even one foot, or adding a new exhaust fan where none existed, you need a permit. The Building Department enforces these because improper drain pitch (less than 1/4 inch per foot) causes backups; improper GFCI means electric shock hazard; improper exhaust means moisture damage and mold. What surprises most homeowners: you cannot simply convert a bathtub to a shower (or vice versa) without a permit, because the waterproofing assembly changes under IRC R702.4.2. A tub only needs a 6-inch tile surround; a shower needs full waterproofing (cement board + membrane, or pre-fab acrylic, or other ICC-approved system). The Building Department will ask you to specify the waterproofing method on your permit application; if you don't know, say 'cement board and liquid membrane' — that's the code-safe baseline and costs $800–$1,200 in materials.

The exhaust fan rule trips up many DIYers. Section M1505.2 says the fan must vent to the exterior; bathroom exhaust ducts in Hopkinsville cannot be shorter than 3 feet in total run, must slope 1/4 inch per foot toward the exit (so condensation drains out, not back into the bathroom), and must terminate through a roof or wall with a damper vent. That duct cannot run through an unconditioned attic space without insulation (IRC M1601.4) — if it does, you'll fail inspection. The frost line in Hopkinsville is 24 inches, so any roof vent that penetrates above the frost line must use an ICC-rated flashing with a vent dam; a cheap Home Depot flashing will leak within 2-3 years. The Building Department requires the rough exhaust duct to be inspected before drywall closes — so you have to call for inspection before the drywall crew arrives. If you skip the inspection and drywall the duct, you'll be tearing it open to re-inspect, at your cost.

Electrical is the second surprise zone. Every bathroom circuit must have GFCI protection (outlets or breaker, your choice). If you're adding a new 20-amp circuit for a heated floor or additional outlets, Kentucky Code Section E3902 applies — the outlets must be GFCI-protected, and the circuit cannot serve outlets outside the bathroom (a common mistake). The Building Department will require an electrical plan showing circuit breaker labels, outlet locations, and GFCI type (outlet vs. breaker). If you're using a licensed electrician, they'll handle this; if you're doing the work and you're the owner-builder, you must pull an electrical permit separately (usually $100–$150 on top of the plumbing/general permit). The rough electrical inspection happens before drywall; the final happens after fixtures are installed. A common rejection: homeowners run bathroom outlets on the kitchen circuit to 'save' a breaker — that's a code violation and will be caught.

Plumbing drain layout is highly regulated. If you're relocating a toilet or sink, the drain trap arm (the horizontal pipe from the fixture to the main vent) cannot exceed 3 feet in length and must slope 1/4 inch per foot toward the drain stack, per IRC P2706. If your bathroom is far from the main stack and the trap arm exceeds code, you'll need a secondary vent (a Studor vent or re-route to the main vent) — this adds $300–$600 in materials and labor. The Building Department will require a plumbing plan showing drain slopes, trap arm lengths, and vent routing. Many homeowners forget to plan this before drywall; when the inspector arrives and measures the trap arm at 5 feet, it's too late. If you hire a licensed plumber, they know the rules; if you're owner-building, get the plumbing plan reviewed by the Building Department at the pre-application stage (free or $50 review fee). The rough plumbing inspection happens after pipes are installed but before drywall; the final happens after fixtures are set.

Hopkinsville's permit timeline and fees: the Building Department is open Monday–Friday, 8 AM–5 PM (verify by calling city hall — (270) 887-4100 is the main number, but building may have a direct line). There is no online portal as of 2024, so you file in person at city hall or by mail; in-person is faster (1-2 days turnaround for intake). Plan review typically takes 2-4 weeks; if the Building Department finds issues (missing waterproofing spec, GFCI not shown on electrical, trap arm length over 3 feet), they'll email or mail a Request for Information, and you resubmit. The permit fee is usually $200–$400 for the general permit, plus $100–$150 for electrical (if adding circuits), plus $50–$100 for plumbing. Once issued, the permit is valid for 180 days; inspections must be scheduled in advance. Rough plumbing comes first (if you're moving drains), then rough electrical (if adding circuits), then framing/drywall (inspector verifies no surprises behind walls), then final (fixtures installed, GFCI tested, exhaust duct confirmed). Total timeline from permit application to final inspection is typically 6-10 weeks if there are no re-inspections. If you remodel in summer, inspectors are busier; in winter, they're faster.

Three Hopkinsville bathroom remodel (full) scenarios

Scenario A

Tile and vanity swap in place (downtown Hopkinsville historic district)

You're keeping the toilet, sink, and tub in their current locations. You're removing the old ceramic tile, the old vanity, and the old medicine cabinet. You're installing new subway tile, a new 30-inch vanity with a new faucet (same rough-in), and new mirror/cabinet. No walls are moving, no electrical circuits are being added, no exhaust fan is being touched. The faucet rough-in is already there (a 4-inch center set, staying 4-inch center set). No permit required. This is surface work. You can pull a permit if you want (Building Department would charge $100 just to review and say 'no permit needed'), but you don't have to. The downside: if you're in the historic district (which Hopkinsville has, near Main Street), the city may have a historic preservation overlay that requires Design Review approval before you touch the bathroom facade or remove any original tile (especially if the tile is 1920s-1960s original). Check with the Hopkinsville Historic District Board before you demo. That's not a building permit, but it's a separate approval that takes 2-3 weeks. Total cost: $3,000–$6,000 for materials and labor, $0 permit fees (no permit required). No inspections.

Scenario B

Moving toilet and sink to opposite wall, new exhaust fan (residential south side)

You're gutting the bathroom. The toilet currently sits on the east wall; you want it on the west wall (about 8 feet away). The sink stays roughly in place (6 inches left), so trap arm is short. You're adding a new exhaust fan with a 4-inch duct running to the roof (about 12 feet total run, including the sloped duct). You're keeping the existing tub. The walls are staying (no load-bearing wall removal). This REQUIRES a permit because: (1) toilet relocation means a new drain line (trap arm must not exceed 3 feet and must slope 1/4 inch per foot — the Building Department will verify this on rough inspection); (2) new exhaust duct must meet M1505 (slope, insulation, damper vent). You'll file a plumbing permit (showing the new toilet drain, trap arm length, vent routing) and a general permit (showing the exhaust duct and roof penetration). If you're adding any new outlets for the bathroom, that's a separate electrical permit. Timeline: 2-4 weeks plan review (Building Department may ask for clarification on trap arm length or vent routing), then 1-2 weeks for rough plumbing, rough electrical (if applicable), framing, and final inspection. The rough plumbing inspection is critical: the inspector will measure the trap arm and slope; if it's over 3 feet, you'll need a Studor vent or re-route the vent stack (adds $400–$600 cost and delays). Total cost: $5,000–$8,000 for labor and materials, $250–$400 permit fees, $100–$150 electrical permit (if applicable). Inspections: rough plumbing, rough electrical (if applicable), final. The south side of Hopkinsville is mostly residential; no special overlay or flood zone concerns — standard code applies.

Scenario C

Tub-to-shower conversion, new waterproofing, wall demo (older home near downtown)

You have an old cast-iron tub in an older home (pre-1978, so lead-paint rules may apply). You want to remove it, Demo the tile surround (only 6 inches high, typical for tub surround), and build a new corner shower with full waterproofing (cement board and liquid membrane), new valve (pressure-balanced), new shower head, and new tile (all four walls, 8 feet high). You're also removing a non-load-bearing partition wall between the bathroom and a hallway closet to gain space. This REQUIRES a permit for multiple reasons: (1) tub-to-shower conversion changes the waterproofing assembly (IRC R702.4.2 requires full waterproofing for showers; a tub only needs 6 inches); (2) wall demolition requires framing inspection to confirm it's not load-bearing; (3) plumbing rough work (new valve location, potentially new drain if the shower pan location differs from the tub drain); (4) if you're changing the valve location, that's plumbing relocation. You'll file a general permit (showing framing and wall removal), a plumbing permit (showing the new valve and drain), and a materials/waterproofing spec sheet (cement board and liquid membrane, brand names, or equivalent ICC-approved system). The Building Department will require a detailed waterproofing plan; if you can't produce one, they'll reject the permit or require you to hire a waterproofing specialist. Timeline: 2-4 weeks plan review (waterproofing spec is the biggest sticking point); 1-2 weeks for framing inspection (to confirm wall is non-load-bearing; if it IS load-bearing, you'll need a beam and posts, which adds 2-3 weeks and $3,000–$5,000), 1-2 weeks for rough plumbing, 1-2 weeks for waterproofing inspection (Building Department may inspect the cement board and membrane application before drywall), then final. Lead-paint disclosure: if the home is pre-1978 and you're disturbing more than 6 square feet of painted surface (which a tub removal definitely does), Kentucky law requires you to notify any occupants or buyers in writing. This isn't a Building Department enforcement item, but it's a state/federal requirement. Total cost: $8,000–$15,000 for labor and materials (includes waterproofing and possible framing for wall removal), $300–$500 permit fees, $100–$150 electrical permit (if touching any circuits). Inspections: framing (if wall removal), rough plumbing, waterproofing (before drywall), final. This scenario is the most complex and highest-risk for rejection if waterproofing isn't clearly specified.

Hopkinsville's waterproofing requirements and the tub-to-shower conversion trap

The single most common rejection Hopkinsville Building Department issues for bathroom remodels is missing or vague waterproofing specification. IRC R702.4.2 (adopted by Kentucky Code) says that showers must have a waterproof barrier. The code doesn't mandate a specific product; it just says 'waterproof.' Most inspectors interpret that as cement board plus liquid membrane (the industry standard for 20+ years), acrylic pre-fab shower pan, or tile on a slope-base mud pan. If your permit application just says 'tile shower' with no mention of the waterproofing substrate, the Building Department will issue a Request for Information asking you to specify the system. Many homeowners panic and submit a photo of something they found on the internet; that doesn't work. The Building Department wants a written spec: 'Schluter Kerdi System' or 'Wedi Building Board Plus Liquid Membrane' or 'Kerdi Board with Mapei Primer' — brand and product name. If you don't know which system to use, stick with cement board (92% of bathrooms in Hopkinsville are built this way) and a liquid waterproofing membrane like Redgard or Hydro-Ban ($400–$600 in materials). Tub surround is different: a bathtub only requires a 6-inch tile surround above the tub rim with waterproofing behind the tile (cement board is standard, but a simple water-resistant drywall will pass inspection). The moment you convert to a shower, the waterproofing must extend the full height and depth of the shower enclosure. This is why tub-to-shower conversions cost more and require a permit — it's not just ripping out the tub, it's a completely different waterproofing assembly.

Hopkinsville's in-person filing system and why it matters for bathroom permits

Unlike Louisville, Nashville, or other major Kentucky cities, Hopkinsville has not deployed an online permit portal. As of 2024, you file your bathroom permit application in person at the City of Hopkinsville Building Department office (in or near city hall) or by mail. This is actually a hidden advantage if you use it right: you can walk in with your plans, speak to a planner face-to-face, and ask 'does this waterproofing spec work' or 'is my trap arm going to be too long' before you officially apply. That 15-minute conversation saves weeks of back-and-forth Request-for-Information letters. The downside is that you must take time off work to visit city hall (8 AM–5 PM, Monday–Friday; confirm phone number at (270) 887-4100). There's no online status tracker, so you can't check permit progress from home; you have to call or visit. For bathroom remodels, plan review typically takes 2-4 weeks from the date you hand in the application. Once the Building Department issues a permit, the issued permit is printed on paper and mailed to you or held for pickup. All inspection requests must be called in or arranged in person (no online scheduler). Most inspectors in Hopkinsville are on-call and respond within 24-48 hours of a request, which is faster than cities with scheduled inspection slots. The lack of an online portal also means there's less data-driven pressure on inspectors, so they tend to be thorough but not punitive; if your rough plumbing is slightly out of spec but correctable, they'll point it out and give you time to fix it rather than failing the inspection outright. For a bathroom remodel that spans 8-10 weeks, budget for 2-3 site visits (including at least one to file the permit) if you're doing owner-builder work.

Common questions

Do I need a permit to replace a toilet in place?

No, if the toilet stays in its current location (same drain hole). Replacing a toilet is surface work: disconnect the water supply, unbolt the old toilet, and install a new one. You do not need a permit. However, if you're moving the toilet even a few feet, or if you're converting from a floor-mounted to a wall-mounted toilet (different drain location), that's a plumbing relocation and requires a permit.

What's the difference between a bathroom remodel permit and a plumbing permit?

They often go together. A general/remodel permit covers the overall project (framing, finishes, inspections). A plumbing permit specifically covers drain/vent/water supply work (fixture relocation, new drains, vent changes). For a bathroom remodel with fixture moves, you'll file both: the general permit and the plumbing permit. Hopkinsville Building Department may issue them as one package or separate, depending on the scope. If you're only moving fixtures, a plumbing-only permit may be sufficient.

Can I do a full bathroom remodel myself, or do I have to hire a contractor?

Hopkinsville allows owner-builders on owner-occupied homes. You can pull the permit in your name and do the work yourself, provided you pass all inspections. However, you must still comply with code (GFCI, waterproofing, exhaust duct slope, etc.). Electrical and plumbing rough work must be inspected before concealment. Many homeowners hire a plumber and electrician but do the demolition, framing, and tile themselves. The permit doesn't care who does the labor; it only cares that the final product is code-compliant.

How long is a bathroom remodel permit valid?

A permit is typically valid for 180 days from the date of issuance. If you don't pull all required inspections within that window, you'll need to renew the permit (usually a small fee, $25–$50). If the project stalls or is abandoned, the permit expires and you'll need to re-apply. The clock also pauses during winter (some jurisdictions don't inspect in harsh weather), so confirm the expiration date with the Building Department when you pick up your permit.

What is a GFCI, and do I really need one in a bathroom?

GFCI stands for Ground Fault Circuit Interrupter — a device that cuts power if it detects a ground fault (electricity flowing where it shouldn't, like through water). It's a shock hazard protection. Kentucky Code Section E3902 requires GFCI protection on all bathroom circuits within 6 feet of a sink, tub, or shower. You can use a GFCI outlet or a GFCI breaker; either works. A GFCI outlet costs $15–$30 and is installed in a standard outlet box. A GFCI breaker costs $50–$100 and replaces the breaker itself. Most homeowners use GFCI outlets in bathrooms. The Building Department will verify GFCI protection on final electrical inspection.

My bathroom is in an older house built before 1978. Do I need to worry about lead paint?

Yes. Kentucky state law (and federal law under the RRP Rule) requires disclosure and caution if the home is pre-1978 and you're disturbing paint during renovation. Removing a tub surround, demo a wall, or sand old painted surfaces triggers the disclosure requirement. You must notify occupants or buyers in writing before disturbing the paint. If you're a homeowner remodeling your own home, the RRP Rule is less strict, but you still must take precautions (wet-sand instead of dry-sand, use HEPA filters, clean up dust). The Building Department doesn't enforce lead-paint rules directly, but they may ask if the home is pre-1978 and what precautions you're taking. A lead-safe contractor has RRP certification; if you're DIY, research EPA RRP practices or hire a certified contractor for the demolition phase.

What happens if I install an exhaust fan duct that vents into my attic instead of outside?

This violates IRC M1505.2 and is a common code violation. Bathroom exhaust venting into the attic causes moisture buildup, leading to mold, rot, and insulation damage. The Building Department will fail the rough inspection and require you to extend the duct to the exterior (through the roof or a wall with a damper vent). Once drywall is up, you'll have to tear it open to re-do the ductwork. The fix costs $400–$800 and delays the project 1-2 weeks. Always vent exhaust fans to the exterior.

How much does a bathroom remodel permit cost in Hopkinsville?

Hopkinsville permit fees for a bathroom remodel typically range from $250 to $500 total, depending on the scope and declared project valuation. A permit-fee calculator uses the estimated construction cost: for a $6,000 remodel, fees are often 1–1.5% of that value (roughly $60–$90), plus a base review fee ($150–$200). If you're adding electrical circuits, add another $100–$150. Plumbing permits are sometimes bundled in the general permit or charged separately ($50–$100). Call the Building Department to confirm the exact fee structure for your project scope; they can give you a pre-application estimate before you file.

Can I change the bathroom layout (move walls, relocate fixtures) without violating code?

Yes, provided you pull a permit and the work meets code. Moving walls, relocating fixtures, and changing the layout all require a permit and inspection. The Building Department will verify that any removed wall is non-load-bearing (or has adequate support if load-bearing), that drain trap arms don't exceed 3 feet, and that vents are properly routed. Many layout changes are totally doable; they just require planning and inspection. If a wall is load-bearing and you want to remove it, you'll need a structural engineer's drawings and a beam installation — that adds cost and time. Have the Building Department pre-review your layout before you start demo.

What is the most common reason a bathroom permit is rejected in Hopkinsville?

Missing waterproofing specification (for shower conversions or new showers). The Building Department asks applicants to specify the waterproofing system (cement board + liquid membrane, pre-fab acrylic pan, Schluter system, etc.), and many homeowners don't have this detail ready. The second most common: exhaust duct vent termination not specified (must go to exterior, not attic, with a damper). The third: GFCI protection not shown on electrical plan. If you submit a detailed, compliant permit application with these three items clearly documented, you'll pass plan review on the first submission.
