Do I need a permit for a full kitchen remodel in
Hilliard, Ohio?

Hilliard full kitchen remodel permits — the key details

The threshold for a permit is any structural, mechanical, or electrical change. Per the 2017 Ohio Building Code (which Hilliard enforces), moving or removing a wall — load-bearing or not — requires a building permit and framing inspection. If the wall is load-bearing (which most kitchen walls dividing the kitchen from a dining room or living room are), you must also submit a signed engineer's letter or beam calculation showing the new support method; this adds 1-2 weeks to plan review and costs $300–$800 for engineering. Plumbing fixture relocation — moving a sink, dishwasher rough-in, or drain line — requires a separate plumbing permit from Hilliard; the plumber must show trap-arm slopes, vent-stack sizing per IRC P2722, and drain diameter (typically 2-inch for kitchen sink). Do not assume your existing drain is the right size; Hilliard inspectors will measure and flag undersized drains. New electrical circuits (dedicated 20-amp small-appliance circuits for countertop receptacles, a 240V circuit for a new range, or a 15-amp circuit for a disposal) require an electrical permit. Two dedicated 20-amp circuits are mandated for kitchen countertop receptacles per IRC E3702; these cannot be shared with other loads, and Hilliard inspectors verify this on the rough-in inspection by counting breakers and checking wire gauge.

Range-hood venting is a common rejection point in Hilliard permit reviews. If you are replacing a recirculating hood with a ducted (exterior-vented) hood, you are cutting through an exterior wall or rim joist, which triggers building-permit review of the penetration. Hilliard staff will require a detail showing the duct diameter (typically 6-inch for a standard hood), the exterior cap type (weather-sealed, bird-proof), flashing materials, and how the duct is supported (straps every 4 feet per IRC M1502). Do not undersize the duct or leave it unflashed; a loose duct leads to water infiltration and mold, and Hilliard inspectors perform a visual check on final inspection. If the range hood vents to the attic or an interior wall (recirculation), no building permit is needed for the hood itself, but you still need an electrical permit if a new 120V outlet is being added. Gas-line changes — adding a new gas cooktop, gas range, or gas water heater — require a plumbing permit (gas work is under the plumbing permit in Ohio). The plumber must pressure-test the line, provide a materials schedule, and show shut-off locations; Hilliard requires a photo of the pressure-test gauge during rough plumbing inspection.

Electrical complexity is often underestimated. A full kitchen remodel with a new range, dishwasher, and disposal typically requires four separate circuits: two 20-amp circuits for countertop receptacles (no other loads), one 20-amp circuit for the dishwasher, and either a 240V circuit for an electric range or a 120V outlet + gas valve for a gas range. Hilliard inspectors count breakers on the panel and verify wire size (12 AWG for 20-amp at 60 feet or less, per NEC 310.15(B)). If your panel is near capacity or full, an electrician may need to consolidate or upgrade the service; upgrading a 100-amp service to 150-amp or 200-amp adds $1,500–$3,500 and requires a separate service-upgrade permit. All kitchen countertop receptacles must be GFCI-protected (either a GFCI outlet or a GFCI breaker); Hilliard inspectors verify GFCI function by pushing the test button at final inspection.

Plumbing details matter for plan review. If the kitchen sink is moving more than a few feet, the drain-line routing must be drawn showing slope (1/4 inch per foot, minimum), trap-arm length (per IRC P2722, typically 30 inches for a 2-inch drain), and venting (vent-stack within 5 feet of trap, or an island vent if the sink is in an island). Undersized drains are the most common failure; a single kitchen sink requires a 2-inch drain, and if a dishwasher is connected to the same trap, the code allows it, but the trap arm and slope must be exact. Hilliard requires the plumber to show the existing drain location and the new drain location on the site plan and to call out the grade/slope on the rough-in drawing. A dishwasher relocation also requires an air-gap fitting at the sink (per IRC P2802) — the small fitting that prevents backflow; inspectors check this at the rough-in.

Lead-paint disclosure and timeline are final details. If your home was built before 1978, you must complete the federal lead-paint disclosure form before starting work; Hilliard does not enforce this directly, but it is a federal requirement, and your contractor must provide it. Hilliard's typical permit timeline is 5-7 business days for initial electronic review (if plans are complete), then a 2-3 week rough-inspection window once work starts. If the plan is incomplete (missing duct details, beam sizing, plumbing venting), you will receive a comment sheet and resubmit; expect an additional 5-7 days for re-review. Inspections occur in sequence: framing (after walls are moved but before drywall), rough plumbing (before walls are closed), rough electrical (before walls are closed), drywall, and final. You must call for each inspection at least 24 hours in advance via the Hilliard portal or by phone; inspectors typically arrive within 1-2 business days. Plan for 10-12 weeks total from permit issuance to final sign-off, assuming no re-inspections.

Three Hilliard kitchen remodel (full) scenarios

Hilliard's 2017 Ohio Building Code enforcement and what that means for your kitchen electrical

Hilliard adopted the 2017 Ohio Building Code (which is the 2015 International Residential Code with Ohio amendments), meaning IRC sections apply directly to your permit review. For kitchen electrical work, the most relevant section is IRC E3702, which requires two small-appliance branch circuits for kitchen countertop receptacles. Many homeowners assume one circuit is enough or that they can split countertop and sink outlets on the same circuit; Hilliard inspectors count breakers and will reject the rough-electrical inspection if two dedicated 20-amp circuits are not present. These circuits must have no other loads (no refrigerator, no range, no disposal) — they are for countertop appliances only (toaster, coffee maker, blender, food processor). Each circuit must serve a maximum of 1,440 watts continuously.

A second detail that trips up many Hilliard kitchens: countertop receptacle spacing. Per IRC E3703, no point along the countertop can be more than 24 inches (horizontally) from a receptacle. This means outlets must be spaced no more than 48 inches apart. Hilliard inspectors measure this on the final inspection, and if an outlet is missing or misplaced, they will request a re-inspection after the outlet is moved. If your countertop has an island, the island must have at least two receptacles (unless it is under 12 square feet, in which case one is permitted). All kitchen countertop receptacles must be GFCI-protected per IRC E3801; you can use a GFCI breaker in the panel, or a GFCI receptacle in the first outlet of the circuit. Hilliard inspectors test GFCI function at final inspection by pressing the test button.

One less-obvious Ohio code amendment: residential kitchens must have a readily accessible outlet within 6 feet of the sink for a wet-location appliance (like a flood pump or sump pump if the kitchen is below grade). This is not always required in other states, and Hilliard inspectors specifically look for it. If your kitchen is on the first floor above grade, this is usually moot, but if the kitchen is in a basement or partially below grade, plan for this outlet. It must be GFCI-protected and typically is a separate 20-amp circuit.

Plumbing complexities specific to Hilliard's clay-till soil and freeze-thaw cycles

Hilliard sits on glacial till with clay and sandstone substrates, and the 32-inch frost depth means any new plumbing lines run underground or in an unconditioned space must be below the frost line or insulated. If you are relocating a sink or dishwasher and running new supply lines in an uninsulated wall (common in basement kitchens or kitchens with exterior walls), Hilliard's inspector will expect those lines to be insulated with foam sleeves or wrapped with heat tape during winter work. This is not always flagged at plan review but will show up at rough-plumbing inspection. For drain lines, the 32-inch frost depth also means any new drain that goes through an exterior wall must be sloped and supported to avoid freezing. Hilliard plumbing inspectors are particular about drain slope: exactly 1/4 inch per foot, measured with a level. If your new island-sink drain is running 10 feet to a stack, it must drop 2.5 inches over that distance, and the inspector will measure it.

A second local detail: Hilliard's water quality is slightly hard (300-350 ppm calcium carbonate), and the city's sewer system is combined in some areas (stormwater and sanitary in the same line). If you are adding a dishwasher and the sink is in an island, the dishwasher drain must connect to the sink trap via an air-gap fitting (a small chrome fitting visible at the countertop), not directly to the drain. This is per IRC P2802, but Hilliard inspectors are strict about it because hard water and clay sediment can clog undersized drains. The air gap adds about 4-6 inches to your under-sink height, so plan cabinet layout accordingly.

Finally, if your kitchen drain currently serves a garbage disposal, and you are removing it or adding a new one, note that Ohio code (per IRC P2720) allows disposals in residential kitchens, but the drain must be sized for the fixture load. A disposal adds water volume, so the drain must remain 2-inch minimum (not 1.5-inch). Hilliard inspectors will note the disposal on the plumbing permit and verify the drain size at rough inspection. If your existing drain is 1.5-inch (common in older homes), adding a disposal requires upsizing the drain to 2-inch, which may mean rerouting the entire drain line — a costly change discovered at permit review, not during demolition.
