Do I need a permit for a full kitchen remodel in
De Pere, Wisconsin?

De Pere full kitchen remodel permits — the key details

De Pere's Building Department administers the 2018 Wisconsin Building Code, which incorporates the 2018 IRC with state amendments. For kitchen remodels, the threshold rule is straightforward: if you move a wall, relocate any plumbing fixture (sink, dishwasher drain, gas line to range), add a new electrical circuit, install a range hood with exterior ducting that requires a wall opening, or change a window or door opening, you need a building permit. The city does not issue 'plumbing-only' or 'electrical-only' permits independently — instead, you pull one building permit and request plumbing and electrical sub-permits under the same job number. This is different from some Wisconsin cities (Madison, Green Bay) that allow licensed plumbers and electricians to pull their own sub-permits without a building permit if the work is minor; De Pere does not. Per city code, owner-builders are permitted on owner-occupied single-family homes, but you must be the property owner and you remain liable for all code compliance. If you hire a general contractor, that GC must be licensed in Wisconsin (state-level requirement, not De Pere-specific), and the GC becomes the permit applicant and responsible party.

Electrical work in a kitchen remodel is heavily regulated because kitchens are 'wet locations' with high shock risk. IRC E3801 requires all kitchen counter receptacles to be protected by GFCI (ground-fault circuit interrupter); outlets must be spaced no more than 48 inches apart measured along the countertop, measured from the outer edge of each receptacle. Many remodelers miss this and place a single 20-amp circuit with 3–4 outlets spaced 60 inches apart, which fails inspection. Additionally, IRC E3702 mandates two separate 20-amp small-appliance branch circuits (one for counter receptacles, one for refrigerator/dishwasher) — these circuits must not serve any other loads in the kitchen or elsewhere, and they cannot be combined into a single larger circuit. A common rejection in De Pere is the electrical plan showing only one small-appliance circuit or showing counter receptacles on a general-purpose circuit. If you're adding a new range hood with exterior ducting, you may need a new 120-volt outlet for the hood motor or a hard-wired connection, which triggers a new circuit; this is a building permit item because the exterior duct opening requires a wall penetration detail. Gas ranges are less common in De Pere than electric, but if your remodel includes a gas range conversion (existing electric to gas, or moving a gas range to a new location), IRC G2406 requires a certified gas installer to perform the work and a licensed plumber or gas fitter to pull the permit. The permit must include a gas-pipe sizing calculation, connection detail, and proof of a gas-line pressure test.

Plumbing work in a kitchen remodel typically centers on the sink and dishwasher. If you're relocating the sink to a new island or opposite wall, the drain line must be rerouted, which requires a new plumbing permit. IRC P2722 specifies that the fixture drain must have a visible trap (P-trap under the sink), and the drain line to the main stack must slope at 1/4 inch per foot minimum and 45 degrees maximum. The trap arm (the horizontal run from trap to vent) cannot exceed 30 inches and must be accessible; this is a frequent failure point in island sinks where the trap is boxed in under cabinetry, making it unreachable. When pulling a plumbing permit, you must submit a plumbing rough-in drawing showing the trap location, arm length, vent routing, and connection to the main stack; a verbal description is not sufficient and will be rejected at intake. The dishwasher drain is less regulated (it's typically a high-loop hose into the sink drain or garbage disposal), but the plan must show the high-loop detail to prevent siphonage. Sink relocation often requires a new vent line; if the existing vent serves multiple fixtures, you may need to add a new vent stack or re-vent through the roof, which adds cost and complexity. De Pere's frost depth is 48 inches, which does not affect interior kitchen plumbing but is relevant if your remodel opens up walls and you later need to know where in-wall supply lines are run — they must be below the frost line or insulated.

Load-bearing wall removal is the most consequential change in a kitchen remodel and the one that most commonly triggers rejection or requires engineering. IRC R602 defines a load-bearing wall as any wall that supports roof/ceiling or floor loads above; in a typical single-story kitchen, an interior wall parallel to the roof ridge or one that sits directly under a second-floor wall is load-bearing. If you want to open up a kitchen by removing a wall, the permit application must include a framing plan with a beam schedule (size, grade, type, support points) and an engineering letter from a Professional Engineer (PE) licensed in Wisconsin. De Pere's plan review will not approve a wall-removal permit without this engineer letter — it's a hard stop. The engineer must certify that the proposed beam (typically a built-up 2x10–2x12 or steel beam) will carry the load without deflection exceeding 1/240 of the span. This engineering work costs $500–$1,200; the beam itself (materials + labor) costs $2,000–$5,000 depending on span and support. Many homeowners discover this requirement late and are surprised by the cost and timeline. De Pere does not offer an over-the-counter (instant) approval for any structural change — all plan-review permits go through the city's engineering review, which adds 4–6 weeks.

Practical next steps after the permit is issued: once the city signs off on your permit, you can begin demolition. However, do not cover any walls, plumbing, or electrical rough-in until the respective inspections are scheduled and passed. De Pere requires inspections in this order: (1) framing/structural (if walls are moved or opened), (2) rough plumbing (sink and dishwasher drain lines, vent routing, before walls are closed), (3) rough electrical (new circuits, outlets, switch locations, before drywall), (4) any gas-line inspection (if applicable), (5) drywall/framing final (after insulation and drywall are in place), and (6) final inspection (countertops, backsplash, appliances, final electrical and plumbing fixtures installed). Each inspection requires 24–48 hours notice to the Building Department; inspectors are typically available Mon–Fri 8 AM–4 PM. Failure to schedule an inspection before covering rough work will require you to open walls or floors to re-inspect, which is costly and delays the project. The entire permit-to-final-inspection cycle typically runs 6–10 weeks if inspections are scheduled promptly and no code issues arise.

De Pere's permit review process and timeline for kitchen remodels

Inspection scheduling in De Pere is a common pain point. Once the permit is issued, you must call the Building Department to schedule inspections; the city does not use an online self-service system (as of 2024, though this may change). You must request inspection availability 24–48 hours in advance, and inspectors are available Monday–Friday, typically 8 AM–4 PM. If you miss a scheduled inspection or the work is not ready (e.g., you haven't completed the rough-in framing), the inspector will not re-inspect until you call and reschedule, adding delays. For a full kitchen remodel with structural, plumbing, and electrical changes, you'll schedule 4–6 separate inspections (framing, rough plumbing, rough electrical, gas-line if applicable, drywall, final). Each inspection must be passed before the next phase; you cannot cover walls or install fixtures out of sequence. De Pere's inspectors are generally responsive and available within 2–3 business days of a request, but commercial permit work takes priority, so residential kitchen remodels may experience delays during spring/summer when contractors are busy. Plan for 1–2 weeks to complete all inspections once the rough-in phases are done.

Lead-paint, cost considerations, and pre-1978 home disclosures in De Pere kitchens

Cost estimates for a full kitchen remodel in De Pere typically run $100–$200 per square foot of kitchen area (materials, labor, permits, inspections). A 150–200 sq ft galley kitchen remodel costs $15,000–$40,000; an open great-room remodel with structural changes costs $40,000–$80,000. Permit fees are 1.5–2% of the 'permit valuation' (the estimated cost of the work), which the city uses to set the fee. De Pere does not cap kitchen-remodel permits at a flat fee; small cosmetic remodels (if they required permits, which they don't) would cost $200–$300, while structural changes can run $600–$1,500. Additionally, if your remodel involves a load-bearing wall removal, budget $700–$1,200 for PE engineering and $2,000–$5,000 for the beam and support framing. If you're relocating plumbing fixtures and need to re-vent or add a vent stack penetrating the roof, add $500–$1,500 for plumbing labor. Many homeowners underestimate the total cost and timeline; plan for a 10–20% contingency buffer on top of the contractor's estimate.
