Hazelwood, Missouri?

Hazelwood kitchen remodel permits — the key details

The decision tree in Hazelwood is straightforward: if your kitchen remodel includes ANY of the following, you need a permit: moving or removing a wall, relocating plumbing fixtures (sink, dishwasher, island drainage), adding or moving electrical circuits (two small-appliance branch circuits are mandatory per IRC E3702 for any kitchen), modifying gas lines (cooktop or range conversion), installing a range hood that vents to the exterior (ducted range hoods require wall/roof penetration and are always permitted work), or changing window or door openings. If your project is strictly cosmetic — cabinet replacement in the same footprint, countertop swap on existing substrate, appliance replacement on existing circuits (as long as the appliance is the same type and amperage), paint, flooring — no permit is required. The reality in Hazelwood is that 95% of full kitchen remodels touch at least one of these triggers, so assume you need permits and build that into your timeline and budget.

The City of Hazelwood Building Department processes kitchen permits under the 2015 IBC (adopted locally with no significant amendments). You'll need three separate permits in most cases: a building permit (covering structural, framing, and egress), a plumbing permit (covering drain, vent, and supply lines), and an electrical permit (covering branch circuits, receptacles, and hardwired appliances). Many kitchens also require a mechanical permit if the range-hood duct is being run through conditioned space or vented through the roof. Plan review typically takes 3–4 weeks from submission; Hazelwood does NOT offer expedited review as of 2024. You submit plans online via the city's permit portal or in person at City Hall. Plans must show: floor plan with dimensions and fixture locations, plumbing riser diagram with trap arms and vent routing, electrical riser with circuit schedule and GFCI locations (every counter receptacle must be GFCI per IRC E3801), and any wall-framing changes with load-bearing wall details (if applicable). Load-bearing wall removals require a professional engineer's letter certifying the beam or header size; this adds 2–3 weeks and $400–$800 to your project.

Hazelwood's permitting office has one quirk worth knowing: they flag kitchen remodels for lead-paint disclosure if the home was built before 1978. Missouri law requires you to disclose lead-paint hazards if disturbing painted surfaces in pre-1978 homes during renovation. If your kitchen is in a pre-1978 house, you'll need to either (a) hire a lead-safe certified contractor, (b) provide proof of lead testing (negative results exempt you), or (c) include a lead-hazard warning in your bid and contract. This is a federal EPA rule, not just Hazelwood, but the city building department will flag it during plan review if the home's age triggers it. The cost of lead-safe work is typically 10–20% higher than standard demolition, so budget $500–$2,000 more if lead is present.

Inspection sequence matters for your scheduling. Once your permit is issued, you'll schedule inspections in this order: rough framing (before drywall), rough plumbing (drain, vent, and supply lines exposed), rough electrical (circuits, boxes, and panel work exposed), drywall/finish inspection (after drywall is hung and mudded), and final (all systems operational, fixtures and appliances installed, trim complete). Each inspection is a separate appointment; Hazelwood's building inspector typically schedules them 48–72 hours after you request. If you fail an inspection (common failures: GFCI not installed on counter receptacles, trap arm too long, or load-bearing header undersized), you fix the issue and reschedule that specific inspection — do not proceed with the next phase. Rework and re-inspection adds 1–2 weeks to your timeline.

Cost-wise, Hazelwood kitchen permits run $300–$1,500 total, typically split across building ($150–$600), plumbing ($100–$400), and electrical ($100–$500), depending on project valuation. Valuation is usually 15–25% of the total project cost; for a $50,000 kitchen, expect $7,500–$12,500 valuation, which translates to $450–$900 in permits. Load-bearing wall removal, HVAC system changes (if the range hood requires ducting upgrades), or gas-line work adds $200–$400 each. Owner-builders can pull the building permit themselves but must hire a Missouri-licensed plumber and electrician to pull their respective permits (or hire a licensed general contractor to pull all three). This is not negotiable in Hazelwood — the plumbing and electrical trades are tightly regulated, and the city verifies contractor licenses before issuing permits.

Three Hazelwood kitchen remodel (full) scenarios

Hazelwood's kitchen permit plan-review process: what to expect and how to avoid rejections

When you submit a kitchen remodel permit package to the City of Hazelwood Building Department, the plan reviewer (typically one inspector wearing multiple hats) checks your drawings against the 2015 IBC and local amendments. The most common rejection reasons for Hazelwood kitchens are: (1) missing or undersized small-appliance branch circuits — IRC E3702 requires two independent 20A circuits just for counter-top receptacles, and the reviewer will reject your electrical plan if you're trying to share circuits with other loads; (2) counter receptacles not GFCI-protected and spaced more than 48 inches apart — IRC E3801 requires GFCI on every receptacle within 6 feet of the sink, and the reviewer will count spacing on your plan and flag violations; (3) range-hood duct termination not shown — if you're venting to the exterior, the reviewer needs to see the duct diameter, routing, and cap detail, and will reject if you've omitted this.

Load-bearing wall removals are rejected 30% of the time in Hazelwood because homeowners submit framing plans without structural engineer letters. Hazelwood does NOT allow you to self-design a beam for a load-bearing wall; you must hire a professional engineer to certify the beam size, posts, footings, and load paths. The engineer's letter costs $400–$800 and takes 1–2 weeks to obtain. If you submit without one, the reviewer will issue a 'request for additional information' (RAI) asking for the engineer's letter — you then have 10 days to resubmit, which delays your approval by 2–3 weeks.

Plumbing rejections often stem from trap-arm length and vent routing. IRC P2722 limits trap-arm length to 5 feet and requires the vent to be sized based on drain-line diameter and slope. Hazelwood reviewers will measure your trap-arm on the plan and reject if it exceeds 5 feet, or if your vent is undersized for the drain load. If you're running a new vent through the roof, the reviewer will flag if there's no roof flashing detail or if the vent termination is too close to a window or roof edge (IRC P3102 requires 10 feet from operable windows in some cases). Gas-line plan rejections are rare but happen if you've omitted pressure-test certification or if the line routing conflicts with electrical circuits (gas and electrical must maintain separation per the NEC).

To avoid rejections, hire a drafter or architect to prepare your plans, and budget 1–2 weeks for drawing time. Provide floor plans with dimensions, electrical riser with circuit schedule and GFCI locations, plumbing riser with trap-arm measurements and vent routing, and any wall-framing changes with load-bearing wall details. If you're removing a load-bearing wall, hire the structural engineer BEFORE you submit the permit; include the engineer's letter in your package. If you're installing a range hood, provide a duct-routing detail showing diameter, slope, and exterior termination. Submit electronically via the Hazelwood permit portal if possible (faster than in-person); expect 3–4 weeks for plan review, and assume you'll get one RAI requiring minor clarifications.

Electrical and plumbing specifics for Hazelwood kitchens: circuits, GFCI, and gas safety

Every kitchen remodel in Hazelwood must comply with NEC Article 210 (branch circuits and outlets) and the 2015 IBC electrical provisions. IRC E3702 mandates two small-appliance branch circuits (20A each) for counter-top receptacles, hardwired to the main panel. These circuits cannot serve anything but kitchen counter outlets and a refrigerator (if hardwired); they cannot be shared with dining-room outlets or other loads. The plan reviewer will verify on your electrical riser diagram that you've shown two dedicated 20A circuits. Every receptacle within 6 feet of the kitchen sink must be GFCI-protected per IRC E3801; modern kitchens have GFCI on EVERY counter outlet, not just the ones closest to water. If you're replacing the cooktop with a hardwired electric model, that cooktop must have its own dedicated circuit: a 240V, 40–50A circuit depending on the cooktop's amperage (check the appliance specs). The plan reviewer will verify the breaker size and wire gauge on your electrical schedule.

For plumbing, IRC P2722 governs kitchen sink and dishwasher drain routing. The trap arm (the horizontal line from the trap to the vent) cannot exceed 5 feet in length; if your sink is more than 5 feet away from the main vent stack, you must install a sanitary tee and a new vent line. The drain slope must be 1/4 inch per foot (checked on plan), and the vent must be sized based on fixture unit load and pipe diameter. If you're adding an island sink, you'll need to drill through the floor joists to run the drain; drilling is allowed per IRC R602 if you reinforce the joist with blocking or nailing plates. The plumbing inspector will verify this during rough-in. A new dishwasher drain must be above the flood rim of the sink bowl (about 24 inches above the countertop) or use an air gap fitting per IRC P2722; the plan must show which method you're using.

Gas-line work in Hazelwood requires a licensed plumber or gas fitter (not a general contractor). If you're converting from electric to gas cooktop, the gas line must be rated for the appliance (typically 3/4-inch black iron or CSST per IFGC), with a shutoff valve within 6 feet of the appliance, and pressure-tested to 10 PSI before final inspection per IFGC 406. The gas permit is separate from the building permit; you cannot conceal the gas line until the rough-in inspection passes. If the gas line runs through an exterior wall or crawl space in Hazelwood's climate zone 4A, ensure proper insulation and drip loops to prevent condensation issues. A licensed plumber will handle this, but verify on your bid that the plumber is insuring the pressure test and final inspection certification.
