The Short Answer
A full kitchen remodel in Danville triggers building, plumbing, and electrical permits in nearly every case—unless you're doing cosmetic-only work (cabinets, countertops, paint in place). Moving walls, relocating fixtures, adding circuits, or venting a range hood to the exterior all require permits.
Danville enforces the 2012 Illinois Building Code (adoption lag behind current IBC, but standards are consistent). The Danville Building Department processes permits in-person at City Hall or through limited online filing—not all jurisdictions in Vermilion County offer online submission, and Danville's portal is less developed than nearby Bloomington or Champaign. This matters because if your contractor is used to electronically filing in a larger city, they may need to hand-carry or mail documents here, adding 3–5 business days to intake. Danville's frost depth is 36 inches (downstate standard), which affects any plumbing-penetration details in your scope. Plan-review timelines run 3–6 weeks depending on complexity; the Building Department has a small staff and prioritizes projects in order received. Load-bearing wall removals require an engineer's letter and beam specification—not a waiver—and that engineering step alone adds 1–2 weeks and $400–$800 to your budget if you haven't already hired an engineer.

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

Danville full kitchen remodel permits—the key details

The Danville Building Department requires three separate permits for nearly every full kitchen remodel: Building (structural, load-bearing walls, window/door changes), Plumbing (fixture relocation, drain/vent sizing), and Electrical (new circuits, GFCI protection, receptacle spacing). If you're adding or modifying a gas line, that's a fourth mechanical permit. If your range hood vents to the exterior with new ductwork cutting through the exterior wall, the Building permit must detail the duct routing and termination cap. The 2012 Illinois Building Code adopted by Danville incorporates the IRC section-for-section, so IRC E3702 (two small-appliance branch circuits, each 20 amps, for countertop receptacles) and IRC E3801 (GFCI protection on all counter receptacles within 6 feet of a sink) are non-negotiable. Many homeowners and even some contractors misunderstand the two-circuit requirement: you cannot run all your counter outlets to a single 20-amp circuit. They must be on two separate circuits, and the plan must show the breaker diagram identifying which counter outlets feed from Circuit A and which from Circuit B. The Danville Building Department will reject any electrical plan missing this detail.

Plumbing is the second major complexity. If you're relocating your sink, dishwasher, or range, the plumbing plan must show trap-arm configuration (the drain-line slope and distance from trap to vent), sink rough-in height, and hot/cold line sizing. IRC P2722 specifies that the sink drain must have a trap, the distance from the trap weir to the vent fitting cannot exceed the vent diameter plus 1 inch times the pipe diameter (roughly 2.5 feet for a 1.5-inch trap arm), and venting must be sized per table P2701.1. Many DIY-minded homeowners try to snake a new drain under the floor and vent it into the attic without understanding these rules; the Danville inspector will catch this at rough-plumbing inspection and mark it rejected. If your existing main drain or venting cannot accommodate the new fixture locations, you may need to add a separate vent loop or tie into a different stack—a cost-adder of $800–$2,000 depending on framing and crawlspace access. Frost depth in Danville is 36 inches, so if plumbing must penetrate below grade (rare in a kitchen but possible in a basement remodel), any vent pipe or supply line crossing the frost line must be sloped or insulated; however, most kitchen work stays above the rim joist, so this is rarely triggered.

Load-bearing wall removal is the third pain point. If your project includes opening up a wall between the kitchen and dining room—a very common request—and that wall is load-bearing, the Danville Building Department requires a signed and sealed engineer's letter or structural plan showing the beam size, grade, and fastening. You cannot simply state 'We're installing a 2x12 header' or 'We'll use a steel beam'—the engineer must certify it for your specific span and load case (dead load plus live load plus snow load for your latitude). Danville's snow load is roughly 15 PSF; the engineer will factor this into the calculation. Obtaining this engineering letter adds 1–2 weeks and costs $400–$800 (a structural engineer in central Illinois typically charges $150–$250 per hour, and a kitchen-wall removal take 2–4 hours). Some contractors try to get away without an engineer letter by claiming the wall is not load-bearing; the Danville inspector will demand proof (a load calculation or engineer letter) before approving the rough-framing inspection. Do not skip this step.

Electrical and gas lines are straightforward but easy to bungle on the permit application. If you're adding a new range (electric or gas) and it requires a dedicated 240V circuit for an electric range or a new gas line for a gas range, both must be shown on the electrical and/or mechanical plan. For a gas range, IRC G2406 specifies that the connection must be a code-approved flexible connector (not solid copper tubing, not old-style 3/8-inch unregulated tubing), with a manual shutoff valve within 6 feet of the appliance and within sight of it. If your gas line is more than 30 feet from the meter and you're adding a fixture, you may need a separate regulator or line-sizing adjustment—the plumbing/mechanical inspector will verify. For an electric range, the 240V circuit must originate from a dedicated breaker (not shared), typically 40–50 amps, and the circuit must be sized and protected per NEC 210.19 and 240.4. A common rejection: applicants show a new range location but don't show where the gas shutoff or the new 240V breaker will be located; the inspector cannot approve the plan without this detail.

The permit process in Danville is in-person submission at City Hall (contact the Danville Building Department directly for current hours and address; as of 2024, they are typically Mon–Fri 8 AM–5 PM). Once submitted, the Building Department will route your application to the plumbing and electrical inspectors for plan review. Timeline is 3–6 weeks depending on completeness and current workload. Once approved, you receive permits and can begin work. Inspections occur in sequence: rough plumbing (after pipes are rough-in but before drywall), rough electrical (after wire pull and box installation, before drywall), framing (if load-bearing work is involved), drywall (rough or finished), and final (all finishes complete, all fixtures installed). Each inspection must pass before you can proceed to the next trade. If an inspection fails, the contractor must correct the deficiency and call for re-inspection (no fee, but adds delay). Plan for 6–10 weeks total from permit application to final sign-off, longer if rejections occur.

Three Danville kitchen remodel (full) scenarios

Scenario A
Cosmetic kitchen refresh—new cabinets and countertops, appliances in place, same electrical layout. North Danville 1970s ranch.
You're swapping out cabinets and countertops but keeping the sink in its current location, not adding new outlets, and not replacing the range or cooktop. The refrigerator, dishwasher, and microwave stay on existing circuits and plugs. You paint the walls and install new flooring. This is cosmetic-only work: no permits required. No plan review, no inspections, no fees. However, if your new countertop installer needs to drill or cut through walls to access water supply or drain lines on the far side of the island (if you're adding an island), and this requires moving plumbing, then you've crossed the threshold and a plumbing permit is needed. Similarly, if your new cabinet layout requires an electrician to add a dedicated outlet for the dishwasher or microwave on a new circuit (because the existing outlet is no longer accessible), that's a new circuit and you need an electrical permit. The line is clear: if you're swapping fixtures or adding circuits, permits apply. If you're keeping all fixtures and circuits exactly as they are—purely cosmetic—you don't need permits. In Danville, cosmetic-only work is the exception, not the rule; most 'full kitchen remodels' involve at least a sink relocation or a range replacement, both of which trigger permits. Talk to your contractor upfront about scope. If they say 'We'll keep the plumbing footprint the same and the electrical the same,' you may have a cosmetic project. If they say 'We'll relocate the sink to the island and add undercabinet lighting,' you need permits.
No permit required (cosmetic only) | Verify with contractor that plumbing and electrical are unchanged | Scope creep risk: adding island or new circuits triggers permits | Total project cost $15,000–$35,000 | $0 permit fees (if truly cosmetic)
Scenario B
Sink relocation to island, new dishwasher circuit, range stays in place. South Danville 1980s split-level, existing gas range.
You're moving the sink from the original perimeter wall to a new island and adding a dedicated 20-amp circuit for a new dishwasher in the island cabinet. The gas range remains in its current location. This triggers a plumbing permit (sink relocation, new drain/vent) and an electrical permit (new 20-amp dishwasher circuit, GFCI outlet in island). No building permit is needed unless you're moving a load-bearing wall to create the island space; if the island is entirely within an open room (e.g., kitchen-to-dining-room opening that was already enlarged years ago), no structural work. Plumbing plan must show: new sink location and rough-in, trap-arm length and slope (from trap to vent connection, typically 2.5 feet max for a 1.5-inch trap arm), new vent routing (can it tie into existing kitchen vent, or does it need its own vent loop to the attic or through the roof?), and new supply lines (hot and cold, typically 1/2-inch copper or PEX). If the existing kitchen vent is already at capacity or if the island is more than 10 feet from the existing vent stack, you may need to run a separate vent up the island and through the roof—cost adder of $1,200–$2,000. Electrical plan must show: the new 20-amp dedicated circuit originating from the panel, the island outlet location (typically 18 inches AFF, centered on the island edge), and GFCI protection (either a GFCI breaker or a GFCI outlet fed by a standard breaker). The two small-appliance branch circuits for counter outlets must also be shown on the plan, even if they're not changing. Frost depth is 36 inches downstate, but the island sits above the rim joist, so no frost-depth issue. Permit fees in Danville run $300–$800 for combined plumbing + electrical depending on valuation (Danville typically charges 1–1.5% of project cost as the permit fee base, with separate charges for plumbing and electrical). Timeline is 3–4 weeks for plan review, then inspections: rough plumbing (before island is drywalled), rough electrical (before island is drywalled), and final (after finishes). Total project time 8–12 weeks.
Plumbing and electrical permits required | Vent relocation may add $1,200–$2,000 | Permit fees $400–$900 combined | GFCI protection on all island outlets mandatory | Island rough-in inspections before drywall closure
Scenario C
Full kitchen gut—new layout with relocated sink and range, island with cooktop, load-bearing wall removal to open kitchen-to-dining. West Danville 1960s colonial, hybrid glacial-till and loess soil.
This is the most complex scenario: you're removing the original sink and gas range locations, adding a new island with cooktop and sink, and removing the wall between kitchen and dining room to create an open plan. The removed wall is load-bearing (verified by visual inspection—it runs perpendicular to joists and was present in the original 1960s framing). This requires four permits: Building (wall removal, new openings, range-hood ductwork if new), Plumbing (sink relocation × 2 fixtures, new drain/vent for island), Electrical (new circuits for cooktop, new circuits for island sink, two small-appliance circuits, range relocation or replacement), and Mechanical (if the cooktop is gas and requires a new gas line, or if a new range hood with exterior ductwork requires framing). Load-bearing wall removal is the gatekeeper: you must obtain a signed engineer's letter specifying the beam (typically a 2x12 or steel beam depending on span and load), grade, bearing, and fastening before the Building Department will issue the Building permit. This adds 1–2 weeks and $500–$800. Once the engineer's letter is on file, the Building permit can be issued, but it will be conditioned on rough-framing inspection before you cover the beam with drywall. Plumbing is complex: the island sink requires trap-arm and vent routing, typically a separate vent loop up through the island framing and through the roof (cost $1,500–$2,500 in labor and materials). The new range location (if moved) requires a new gas line with shutoff valve within 6 feet of the range; this is mechanical-permit territory if gas is involved. If you're switching to an electric cooktop and removing gas entirely, you still need the mechanical permit to cap the gas line and verify the meter is safe. Electrical must show the new cooktop circuit (typically 40-amp 240V if electric, or 20-amp circuit plus 240V outlet if dual-fuel), the island sink circuit (20-amp GFCI), the two small-appliance circuits for all counter outlets (spacing per IRC E3801: no outlet more than 48 inches from another, GFCI on every outlet in the kitchen). The two-circuit requirement is non-negotiable and is the #1 rejection reason in Danville. A new range hood with exterior ductwork (if you're venting a hood over the cooktop to the exterior wall) requires the Building permit to show duct routing through framing, termination cap location, and wall opening size. Frost depth in this region is 36 inches; if plumbing penetrates the rim joist, the PEX or copper must be sloped or insulated, but this is standard practice and not a major cost adder. Soil in the west Danville area is glacial till (dense, low permeability) and some loess deposits; this does not affect the kitchen permit directly but may affect foundation or exterior drainage if the new ductwork opening is near grade. Permit fees are higher for a full renovation: $1,200–$2,500 combined (Building, Plumbing, Electrical, Mechanical) depending on total project valuation. Plan review is 5–6 weeks due to complexity. Inspections occur in this order: rough framing (beam installation and bracing), rough plumbing (before island is drywalled), rough electrical (before island is drywalled), framing final (beam concealment and bracing verification), drywall, final (all finishes, all fixtures, all rough-in plugged and tested). Total project duration 14–20 weeks from permit application to final inspection sign-off. Do not underestimate the engineer's letter timeline and cost; many homeowners are surprised that the engineer step adds 2–4 weeks and $500–$800 to the budget.
Building, plumbing, electrical, mechanical permits required | Engineer's letter for load-bearing wall removal required (add $500–$800, 1–2 weeks) | Island vent loop add $1,500–$2,500 | Gas line cap or relocation add $300–$700 | New range-hood ductwork add $400–$800 | Total permit fees $1,200–$2,500 | Plan review 5–6 weeks | Total project 14–20 weeks

The two small-appliance branch circuit trap—and why Danville inspectors are strict about it

IRC E3702 requires two separate, dedicated 20-amp circuits for kitchen countertop receptacles and a 20-amp circuit for the refrigerator. Many contractors and homeowners incorrectly assume they can run all counter outlets to one 20-amp circuit or combine the fridge circuit with counter circuits. The Danville Building Department's electrical inspector will reject any plan that shows this configuration. The rule exists because small appliances (toaster, coffee maker, mixer, blender) can draw 10–15 amps each, and if two are running simultaneously on one circuit, the load exceeds 20 amps and the breaker trips—or worse, if the breaker is undersized or bypassed, an overheated wire starts a fire. Two separate circuits ensure that toaster and coffee maker can run together without exceeding the per-circuit load. The refrigerator gets its own circuit because it runs constantly and must not be shared with intermittent loads.

On your electrical plan submitted to Danville, you must clearly show which counter outlets are on Circuit A (e.g., west wall and island north side) and which are on Circuit B (e.g., south wall and island east side). You must also show the breaker position in the panel diagram. If your existing panel is full and you cannot add two new breakers, you will need a sub-panel or a panel upgrade—a cost adder of $1,500–$3,000. The Danville inspector will verify this during rough-electrical inspection by checking that the correct breakers are installed, the wire gauge matches the breaker amp rating (12 AWG for 20 amps, 10 AWG for 30 amps), and the outlet boxes are properly positioned at standard height (typically 42–48 inches AFF for countertop outlets, 18 inches AFF for island outlets, 48 inches for cabinet-top outlets).

If you're remodeling an older home built in the 1950s or 1960s, the existing panel may have only 100-amp service with a dozen breaker slots already full. Adding two 20-amp circuits for small appliances plus a 40-amp circuit for a new electric cooktop may require a service upgrade from 100 amps to 150 or 200 amps. This is a separate permit (electrical service upgrade) and costs $2,000–$4,500 depending on meter location and utility company requirements. The Danville Building Department will flag this during plan review; factor this into your budget estimate before you finalize your scope with the contractor.

Range-hood ductwork, venting, and the termination-cap detail Danville requires

If your kitchen remodel includes a new or relocated range hood with ducting to the exterior, the Building permit plan must show the duct routing from the hood, through walls or ceiling cavities, to the exterior wall, and the termination cap detail. Many DIY or inexperienced contractors vent a hood to the attic (a code violation that can void your permit and cause mold/moisture damage) or terminate a duct on the exterior wall without a proper cap (allowing rain and pests to enter). The Danville Building Department requires a detail drawing showing the exterior termination: typically a 5-inch or 6-inch round (or rectangular equivalent) duct emerging through the exterior wall, with a damper flapper and a screen-equipped cap. If the hood is on an exterior wall (e.g., kitchen on the back of the house), the duct run is short and straightforward. If the hood is on an interior wall (e.g., island cooktop), the duct must run horizontally or upward through the ceiling to find an exterior wall, adding length and complexity.

Duct length and diameter affect static pressure and airflow. A duct run longer than 25 feet may require a larger diameter (6-inch instead of 5-inch) or a booster fan to maintain adequate CFM (cubic feet per minute). The plan must specify the hood CFM (typically 600–1,200 CFM for a 30-inch cooktop), the duct diameter, and the run length. If the run exceeds code limits, a booster fan must be shown on the plan. The Danville inspector will measure the duct run during rough-electrical or mechanical inspection (whichever applies) and verify that it complies. A duct run of 30+ feet with poor slope or multiple elbows will cause the inspector to require a booster fan or duct redesign.

In Danville's downstate climate, exterior ductwork on the north face of a house may accumulate condensation or ice in winter, especially if the hood is not used frequently and the duct cools. A make-up air system (outdoor air inlet to replace exhausted kitchen air) is not always required by code, but it is good practice in cold climates to prevent backdrafting of other combustion appliances (furnace, water heater) and to reduce pressure imbalances. If your contractor recommends a make-up air system, it will add $500–$1,500 to the budget and may require its own duct routing. The Building Department does not mandate this for a standard kitchen hood, but ask your HVAC contractor if it's advisable for your home.

Common questions

Do I need a permit to replace my kitchen cabinets and countertops if I keep the sink and appliances in the same place?

No permit is required if you are only replacing cabinets and countertops without moving plumbing or electrical. This is considered cosmetic work. However, if the cabinet installer needs to relocate any plumbing lines or water supply to access the new layout, or if new outlets are needed that are not on the existing circuit, a plumbing or electrical permit becomes necessary. Confirm the scope with your contractor in writing before starting work.

Do I need an engineer's letter to remove a load-bearing wall in my kitchen?

Yes. Danville's Building Department requires a signed and sealed engineer's letter specifying the beam size, grade, bearing, and fastening for any load-bearing wall removal. The engineer must verify that the proposed beam (typically a 2x12 or steel beam) is adequately sized for the span and the design loads (dead load, live load, snow load). This adds 1–2 weeks and $400–$800 to your budget. Do not proceed with wall removal until the engineer's letter is approved and the Building permit is issued.

What is the cost of a full kitchen remodel permit in Danville?

Permit fees for a full kitchen remodel in Danville range from $300 to $2,500 depending on the scope and project valuation. Danville typically charges 1–1.5% of the project cost as a permit fee base, with separate line items for plumbing ($100–$500), electrical ($100–$500), and mechanical ($50–$300). A typical full remodel with sink and range relocation costs $1,000–$1,500 in total permits. Ask the Building Department for a detailed fee schedule before you file.

Can I do the work myself if I'm the homeowner, or do I need a licensed contractor?

Illinois allows owner-builders to perform work on owner-occupied residential properties, including kitchen remodels. However, you must obtain the permits (just as a contractor would) and pass inspections. For structural work (load-bearing wall removal), you will still need an engineer's letter. For plumbing and electrical, you can perform the work yourself only if you are the owner, but some municipalities restrict certain work. Contact the Danville Building Department to confirm current owner-builder rules; they may require you to be present during inspections.

How long does the permit plan-review process take in Danville?

Plan review for a kitchen remodel in Danville typically takes 3–6 weeks from submission, depending on completeness and staff workload. A simple scope (sink relocation only) may be approved in 2–3 weeks. A complex scope (wall removal, full replumbing, electrical service upgrade) may take 6–8 weeks. Once approved, you receive the permits and can begin work. Inspections are scheduled separately and must occur in sequence (rough plumbing, rough electrical, framing, drywall, final).

What are the most common reasons the Danville Building Department rejects a kitchen permit application?

The top rejections are: (1) missing the two small-appliance branch circuits on the electrical plan, (2) inadequate counter-receptacle spacing (more than 48 inches between outlets, or missing GFCI protection), (3) plumbing plan missing trap-arm and vent detail or showing an illegal venting configuration (e.g., venting into the attic), (4) range-hood ductwork termination not shown or terminating into the attic, and (5) load-bearing wall removal without an engineer's letter. Ensure your contractor submits a complete plan addressing all of these points.

What happens during the rough-plumbing inspection for my kitchen remodel?

The rough-plumbing inspection occurs after all drain lines, supply lines, and vents are installed but before drywall is closed. The inspector will verify that trap-arm distances and slopes are correct, that vents are properly sized and routed to the roof or stack, that supply lines are adequately supported and protected, and that any new fixtures (sink, dishwasher) are rough-in correctly. If the island sink vent is undersized or routed illegally, the inspector will mark it rejected and you must correct it before the drywall can be closed.

Can I relocate my gas range to a new location during my kitchen remodel?

Yes, you can relocate a gas range, but a gas line must be run from the meter or existing line to the new location, and the connection must include a manual shutoff valve within sight and within 6 feet of the range. The plumbing/mechanical plan must show the new gas line route and valve location. If the relocation requires a long run (more than 30 feet) or a new regulator, the mechanical inspector must approve the sizing. This is typically included in the mechanical permit if you have one; if not, you may need a separate mechanical permit for gas work.

Do I need to disclose my unpermitted kitchen work when I sell my house in Illinois?

Yes. Illinois Real Estate Transfer Disclosure (RETS) requires sellers to disclose material facts about the property, including unpermitted renovations or repairs. Buyers have a right to know that work was done without permits. Non-disclosure can expose you to liability, contract rescission, or legal action by the buyer. Additionally, the lender's appraiser may flag unpermitted work, and the lender may refuse to finance the property until the work is retroactively permitted and inspected. It is far better to permit work upfront than to face these issues at resale.

What is the frost depth in Danville and how does it affect my kitchen plumbing?

Danville's frost depth is 36 inches (downstate Illinois standard). This affects any plumbing that penetrates the rim joist or crawlspace wall: water supply and drain lines must be sloped or insulated below the frost line to prevent freezing. However, most kitchen work stays above the rim joist, so this is rarely an issue. If your remodel includes a basement-level sink or a drain line that runs below grade, ensure the pipe is insulated or sloped away from the foundation to prevent frost heave or freezing.
