Kearns, Utah?

Kearns full kitchen remodel permits — the key details

Kearns Building Department enforces the 2024 International Residential Code (or the most recent adopted version; confirm with the department). The critical threshold: any kitchen remodel that involves wall movement, plumbing relocation, new electrical circuits, gas-line modification, range-hood exhaust venting through an exterior wall, or window/door opening changes requires a permit. The IRC R602.3 rule on load-bearing walls is strict here — if you're removing or modifying a wall in a kitchen, you must provide either a licensed engineer's letter confirming the load path or engineer-signed beam calculations. Kearns' building staff will reject plan sets that show wall removal without these documents, so budget an extra 2–3 weeks if you need to hire an engineer. The seismic zone also means that any structural modification must account for lateral bracing and connection details per IRC R602.11; this is not optional and cannot be waived. If your kitchen renovation involves relocating the sink, moving the range, or adding a dishwasher, you'll need a plumbing permit and separate inspections for rough plumbing before drywall and final plumbing after finish. Similarly, any new appliance branch circuits, GFCI outlets, or lighting additions require an electrical permit and rough and final electrical inspections.

Kearns' plumbing code (UPC-based) requires specific details on kitchen drain design that often catch homeowners off guard. The kitchen sink drain must have a properly sized trap arm (per UPC Table 803.3), and if you're relocating the sink more than a few feet from its current location, you may need to relocate or add a vent stack. The sink drain also cannot be oversized; a 2-inch drain for a kitchen sink is standard, but oversizing it to avoid a trap arm is not permitted and will be flagged during rough plumbing inspection. Additionally, if you're adding a dishwasher or garbage disposal, those fixtures must have separate drains or be properly combined into the main sink drain with engineered sizing — you cannot simply tee them into the existing drain without review. The two small-appliance branch circuits (IRC E3702) are mandatory in kitchens: at least two 20-amp circuits are required, one for countertop receptacles and one for the refrigerator circuit. These must be drawn on the electrical plan, and counter receptacles must be spaced no more than 48 inches apart, with GFCI protection on every outlet. Many homeowners and even some contractors miss this detail, so expect the electrical plan reviewer to require this correction if it's not shown initially.

Range-hood venting is a major focal point in Kearns kitchen permits. If you're installing a new range hood with exterior ducting (venting through a wall), you must show the duct diameter, termination location, and exterior cap detail on your plan set. The duct must be a minimum of 4 inches in diameter (or comply with the hood manufacturer's specifications), and it must terminate at an exterior wall — not into the attic, crawlspace, or soffits. Flexible duct is permitted, but rigid or semi-rigid duct is preferred and will pass inspection faster. The exterior termination must include a damper or check valve to prevent backdrafting. Many plan rejections in Kearns stem from missing this detail, so if you're adding a range hood, have the exact duct routing and exterior termination planned before you submit. Gas-line modifications (adding a gas range or converting from electric) also require a separate mechanical or gas permit in many cases — confirm with the city whether this is a separate permit or rolled into the building permit. Gas connections must be made by a licensed gas fitter, and the plan set must show the gas line routing, size, and connection point. Kearns does not allow homeowner-installed gas work, so this is a licensed-trade-only item.

The permit fee structure in Kearns is based on the construction valuation. A typical full kitchen remodel (including cabinetry, countertops, appliances, flooring, and all MEP work) valued at $25,000–$50,000 will trigger a building permit fee of $200–$400, a plumbing permit fee of $100–$250, and an electrical permit fee of $100–$250, for a combined total of roughly $400–$900. If you're also adding a range hood with ducting or a gas line, add another $50–$100 for a mechanical permit. Plan review turnaround is typically 10–15 business days for the initial submission; if revisions are required (which is common for kitchen projects), add another 5–10 days for resubmittal and re-review. Inspections are sequential: rough plumbing (before drywall), rough electrical (before drywall), framing/structural (if walls are moved), drywall (to verify interior work), and final (after all finishes are complete). Each inspection takes 1–2 business days to schedule once you call the permit office, so plan for 3–4 inspection trips over a 3–4 month project timeline. Owner-builders are allowed to pull permits for owner-occupied homes in Kearns, but electrical and plumbing work must be performed by licensed contractors — you cannot do the electrical or plumbing yourself, even as the owner.

Pre-1978 homes in Kearns require lead-paint disclosure if you're disturbing painted surfaces (drywall, trim, cabinets). If your kitchen was built before 1978 and you're doing any drywall removal or cabinet work, you must provide a lead-disclosure form and may need to hire a licensed lead abatement contractor for renovation work. This is a federal requirement (EPA RRP Rule), not just a city rule, but Kearns inspectors will ask to see documentation. Additionally, if your kitchen remodel involves any structural work or crawlspace access, have the contractor check for active radon venting — Utah homes are in a high radon zone, and if the home doesn't have a radon mitigation system, this is a good time to install one (though not required by permit, it's a health best practice). Finally, verify with Kearns Building Department whether the city uses an online portal for permit status tracking; if so, you can track your plan review status in real time, which helps avoid surprise rejections late in the cycle.

Three Kearns kitchen remodel (full) scenarios

Kearns' seismic zone and structural requirements for kitchen walls

Kearns sits within Seismic Design Category B per the USGS hazard map and the International Building Code. This designation, driven by proximity to the Wasatch Fault, means that any structural modification — including wall removal or additions — must account for lateral forces and proper connection details. The IRC R602.11 rules on bracing and connection are enforced strictly by Kearns Building Department staff. If you're removing a load-bearing wall in your kitchen, the new beam that replaces it must not only carry the vertical load but also be designed to resist lateral (seismic and wind) forces. This is why an engineering letter or engineer-signed calculations are required; the city does not permit structural work on assumptions or rules of thumb. A typical beam replacement might involve a 6-by-12 engineered rim board or a steel beam (W8x18 or similar), supported on posts that are anchored to the foundation with bolts per IRC R602.11.4. The posts themselves must be properly braced with diagonal straps or knee-braces to prevent lateral movement. Many plan rejections in Kearns stem from showing a beam but not the support details or lateral bracing. If you submit a plan that omits these details, expect a request for resubmittal. Hiring a structural engineer upfront ($300–$500 for a kitchen beam letter) saves weeks of back-and-forth with the building department.

The seismic requirement also affects plumbing and electrical rough-in. Gas lines and water supply lines must have flexible connections near the main shut-off to allow for lateral movement during seismic activity. Similarly, electrical conduit and connections must not be rigid in ways that could snap during movement. Kearns inspectors are particularly attentive to these details during rough inspections. If your kitchen is in a pre-1980 home without seismic bracing, the new work must be brought up to current code — this may mean adding cripple-wall bracing or foundation bolting, which is outside the kitchen permit but should be discussed with your contractor before renovation begins.

The Wasatch Fault seismic considerations also influence the permitting timeline. Because structural review is required for any wall work, Kearns may use an external structural reviewer, which adds 2–3 weeks to plan review. Budget accordingly if you're planning a kitchen with structural modifications. The city's online permit portal will show your plan review status, so you can track when it moves from 'under review' to 'approved with conditions' or 'revision required.' This transparency helps avoid surprise delays.

UPC plumbing code and kitchen drain sizing in Kearns

Kearns enforces the Uniform Plumbing Code (UPC), not the International Plumbing Code (IPC) used in some states. This distinction matters for kitchen drain sizing and venting. Per UPC Table 803.3, a kitchen sink drain must be 2 inches in diameter (larger than a bathroom sink, which is 1.5 inches). If you're relocating a sink, the new drain line must be sized at 2 inches from the trap to the main waste stack. The trap arm (the horizontal section between the sink and the vertical vent) must have a slope of 1/4 inch per foot (per UPC Table 804.1) and cannot exceed a certain length depending on the drain size — for a 2-inch drain, the maximum trap-arm length is typically 8 feet without an intermediate vent. If your kitchen sink relocation requires a trap arm longer than 8 feet, you must install a vent stack or extend the existing vent to within code limits. This is a common point of confusion because homeowners often assume the drain can just run horizontally to the main stack, but UPC requires proper venting to prevent trap seal loss and siphoning. The rough plumbing inspector will verify trap slope with a level; a common rejection is a trap arm that's too flat, which slows drainage.

Another UPC-specific rule for kitchens: if you're adding a garbage disposal or dishwasher to an existing sink, those fixtures must be properly integrated into the drain. A garbage disposal must be discharged into a trap ahead of the sink drain (per UPC 422.1), and a dishwasher discharge line must either connect to the disposal inlet (if present) or to a wye fitting in the drain. You cannot simply tee the dishwasher directly into the sink P-trap without a backflow preventer or proper connection detail. Kearns inspectors will require these details on the plumbing plan before rough-in. If you're unsure whether your layout complies, ask the plumbing contractor to include a detailed isometric drawing of the sink and drain connections on the permit application.

Water supply lines for the relocated sink must also be sized and routed per UPC. The supply lines must be 1/2 inch (or larger) and have shut-off valves both at the main and at the fixture (per UPC 606.1). If you're adding a dishwasher, it requires its own 1/2-inch supply line with a shut-off valve at the fixture. Hot and cold lines must be labeled and routed to minimize the distance from the water heater (to reduce heat loss and wait time for hot water). Kearns plumbing inspectors are increasingly attentive to water-conservation measures, so efficient routing and proper valve placement are expected on modern permits. The rough plumbing inspection will include a water-pressure test (typically at 50 PSI) to verify there are no leaks before drywall is installed.
