Edwardsville full kitchen remodel permits — the key details

Edwardsville requires a building permit for any kitchen remodel where you're moving/removing walls, relocating plumbing fixtures, adding electrical circuits, modifying gas lines, installing a range hood with exterior ductwork, or changing window/door openings. The trigger is structural or MEP work — if you're just swapping cabinets, countertops, flooring, or replacing an appliance on the same electrical circuit and same plumbing hookup, no permit is needed. The city's permit process is unified: you file one application and pay one permit fee (typically $300–$1,500 depending on the declared project valuation), but the plan review covers building/plumbing/electrical codes simultaneously. Edwardsville Building Department will assign separate inspection sign-offs for rough plumbing, rough electrical, framing (if walls move), drywall, and final, but you only pull one permit. The 2021 Illinois Building Code (which Edwardsville adopts) references the IRC heavily, so IRC E3702 (small-appliance circuits), IRC E3801 (GFCI protection), IRC P2722 (kitchen drain sizing), and IRC G2406 (gas appliance connections) are enforced exactly as written.

Plan review in Edwardsville typically takes 3–6 weeks from submission to first-round comments. The city expects a complete package: architectural floor plan showing wall moves/removals with dimensions, electrical single-line or panel schedule showing all new circuits (both 20A small-appliance circuits required by code), plumbing isometric or plan showing all fixture relocations with trap-arm and vent routing, mechanical details for range-hood termination (including exterior wall duct and cap details), and a signed engineering letter if any wall removal is load-bearing. Common rejections include missing the two required small-appliance branch circuits (IRC E3702.12), counter receptacles spaced more than 48 inches apart without GFCI protection, range-hood ductwork not detailed at exterior wall penetration (Edwardsville inspectors will ask to see the duct termination cap and clearance to windows), plumbing trap-arm lengths exceeding code (IRC P3005.1), and missing gas-appliance clearances if a gas range or cooktop is involved. If your home was built before 1978, you must submit (or the city will ask for) an EPA Disclosure of Lead Paint Hazard form; this does not stop the permit but is required for compliance and shows up on plan-review checklists.

Edwardsville allows owner-builder permits for owner-occupied residential work, but full kitchen remodels rarely qualify because most homeowners don't hold electrical or plumbing licenses and can't self-sign rough electrical/plumbing inspections. If you are licensed (or hire licensed subs to self-permit their work), the city will issue permits to individuals. Otherwise, hire a general contractor licensed in Illinois (or a kitchen-specific firm) who can pull the master building permit and then pull or coordinate electrical and plumbing permits. Permit fees in Edwardsville are calculated on declared project valuation; a typical mid-range kitchen remodel ($50,000–$100,000) will run $500–$1,000 in permit fees (roughly 1–1.5% of valuation). If you're doing high-end work ($100,000+), budget $1,200–$1,500. The fee includes building, plumbing, and electrical reviews; mechanical (range-hood vent) is usually bundled into the building permit unless you're installing a major ventilation upgrade.

Inspections will include rough plumbing (after fixtures are rough-in'd but before walls close), rough electrical (after new circuits and GFCI outlets are installed), framing/structural (if walls move), drywall (after moisture-sensitive work is verified), and final (after finish surfaces and appliances are installed). Each inspection requires a city inspector to visit and sign off; expect 1–3 day turnaround to schedule. Edwardsville's Building Department accepts inspection requests through the permit portal or by phone; you'll need to call in advance (typically 24–48 hours notice). Plan to have subs present for rough inspections so the inspector can ask questions about concealed work. Gas-appliance connections require final inspection by a qualified inspector; if you're installing a gas range or cooktop, the installer or GC must be on-site for that final check.

If your kitchen includes a range hood with exterior ducting, Edwardsville requires that the ductwork terminate at an exterior wall with a weather cap and proper clearance (typically 12 inches from windows and doors per IRC M1502.4). Many DIY or budget contractors install ductwork that runs to the soffit or ridge, which can pull moist air into the attic and cause mold — the inspector will reject this. Provide a detail drawing showing the exit point, cap style, and clearance. Similarly, if you're moving plumbing, the new drain line must slope properly (1/8 inch per foot per IRC P3005), have accessible traps, and vent within distance limits (IRC P3103); sketches on the plan showing these details prevent rejections and rework.

Three Edwardsville kitchen remodel (full) scenarios

Load-bearing wall removal in Edwardsville kitchens — structural and code requirements

If your kitchen remodel involves removing or significantly modifying a wall, Edwardsville requires a structural engineer's letter and beam design. Most kitchen walls that separate the kitchen from dining or living areas are load-bearing (carrying the roof and/or upper floors), and removing them without proper support will cause ceiling sagging, cracking, or collapse. The IRC R602 requires that the replacement beam (typically an LVL, steel, or solid-sawn lumber member) be sized by a licensed engineer or architect and that the design be stamped and submitted with the permit application. Edwardsville's plan review includes a structural check; the building official will not approve wall removal without the engineer's letter. If you skip the engineering step and remove the wall anyway, you're violating city code and risking dangerous conditions — an inspector or your home insurer (on claim denial) will catch it.

Beam sizing depends on the wall's span (distance it must bridge), the load it carries (roof, upper floor, or both), and your soil/foundation conditions. A typical kitchen wall removal (12–16 foot span, single story below) might require a 2x12 or 2x14 LVL beam or a W8x18 steel I-beam; cost runs $1,500–$3,500 for engineer design and materials. The engineer will also specify bearing details (how the beam sits on the walls at each end — typically 3.5–4 inches minimum bearing per IRC R602.7.2). During plan review, Edwardsville's building official checks the engineer's calcs against code and local soil data (Edwardsville sits on glacial till and loess, which have different bearing capacities than sand or clay — the engineer factors this in). After approval, the beam must be installed under inspection; the city will schedule a framing inspection after the beam is in place and temporary posts are removed, to verify that the bearing points are adequate and the beam is level.

If you're installing the beam yourself (owner-builder), you must hire the engineer and the installer; the city will not waive the engineer requirement. The permit application must include the engineer's letter, beam detail, bearing detail, and connection details if the beam ties into existing masonry or steel. Plan review will add 1–2 weeks because of structural scope. Once the permit is approved, order materials early — LVL lead times are often 2–3 weeks — and schedule the beam installation during a main framing inspection window (typically the same inspection that covers rough plumbing and electrical, so coordinate subs).

Kitchen plumbing relocation in Edwardsville — drain sizing, venting, and frost-depth considerations

Relocating plumbing in a kitchen remodel is common and triggers a plumbing permit in Edwardsville. The IRC P2722 specifies kitchen sink drain sizing and trap-arm requirements: a kitchen sink drain must be at least 1.5 inches in diameter, the trap-arm (horizontal run from the trap to the vent) cannot exceed 2 feet 6 inches in length without a vent (IRC P3005.1), and the vent stack must be sized and routed per IRC P3101–P3103. Many DIY-friendly kitchens with island sinks fail inspection because the trap-arm is too long or undersized, or the vent is missing or routed incorrectly (e.g., too high in the wall, creating an air lock). Edwardsville's plumbing inspector will require a detailed isometric or plan drawing showing the new sink location, trap-arm routing and length, vent routing and size, and how the line ties into the main stack or drain. If you're moving the sink far (e.g., from north wall to a new island in the center of the kitchen), you may need to relocate or install a new vent stack, which adds cost ($1,000–$2,500) and complexity.

Edwardsville's 42-inch frost depth (for the city's northern latitude in Illinois) affects basement or crawlspace plumbing relocations. If your kitchen drain line runs through a basement or crawlspace, it must be sloped properly (1/8 inch per foot minimum) and protected from freezing if it's in an uninsulated area. New drains in older Edwardsville homes often run through crawlspaces with minimal insulation; the plumbing code requires either insulation of the line or burial below frost depth. Most contractors run new drain lines inside the heated footprint (through walls or floors) to avoid this. The plumbing permit application must show the drain route — if it's in a cold area, the plan must note insulation or depth. Inspect or's will not pass rough plumbing if a new drain in a cold zone is exposed and uninsulated.

Gas-line relocation (if you're moving from a wall-mounted gas stove to an island cooktop with gas, for example) requires gas-line permitting in Edwardsville. Gas lines must be sized per the appliance BTU load, fitted with a shutoff valve within 6 feet of the appliance, and tested for leaks before final approval. If the new gas line is longer than the old one, you may need a larger line size; the plan must show the route and sizing. Plan review will check that the line does not cross electrical conduit without spacing (minimum 12 inches per NEC 300.3), and that the shutoff valve is accessible. Gas-appliance final inspection often requires a qualified technician (your contractor's plumber or the gas utility); Edwardsville will not sign off until the utility has tested the connection.
