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

Franklin full kitchen remodels — the key details

Franklin requires a building permit whenever you move or remove any kitchen wall, relocate any plumbing fixture (sink, dishwasher drain, supply lines), add a new electrical circuit, modify a gas line, vent a range hood to the exterior (which involves cutting the wall), or alter any door or window opening. The core rule is Wisconsin IBC Section R603, which requires permits for any 'work that impacts structural elements, mechanical systems, or code-required electrical infrastructure.' Even if your contractor says 'it's just moving cabinets,' if those cabinets sit in front of a structural wall or if the plumbing drain requires rerouting, a permit is triggered. The City of Franklin Building Department interprets this broadly: a single relocated 2x4 wall stud or a single relocated sink drain = permit required. The exception is purely cosmetic work — in-place cabinet face-lift, countertop replacement with the same sink hole, appliance swap on existing circuits, paint, and flooring — which do not require permits. The city's online portal (accessible via the Franklin WI city website) allows you to submit permit applications 24/7, but the Building Department reviews submissions during business hours (typically Mon–Fri 8 AM–5 PM) and responds within 2–3 business days with either approval, minor comments, or a rejection requiring resubmittal.

Electrical code in Franklin kitchens is heavily enforced, particularly around small-appliance branch circuits and GFCI protection. Per NEC Article 210.11(C)(1) (adopted by Wisconsin), every kitchen must have a minimum of two separate 20-amp branch circuits serving the countertop receptacles, and all countertop receptacles must be GFCI-protected. The City of Franklin Building Department rejects nearly 40% of kitchen electrical plans on first submission because homeowners or contractors fail to show both circuits clearly on the drawing or fail to label which outlets are GFCI. The rule is simple: receptacles must not be spaced more than 48 inches apart (measured along the countertop), and every receptacle within 6 feet of a sink must be GFCI. If you're adding an island, the island must also have its own receptacles (not extension cords) at 48-inch intervals, each GFCI-protected. Dedicated circuits for high-draw appliances — range, dishwasher, microwave (if hardwired), garbage disposal — are also required; the city's electrical inspector will request a panel load calc if you're adding more than one dedicated circuit, to ensure the service panel has capacity. Most kitchens require a 200-amp service; if you have an older 100-amp panel and are adding circuits, you'll likely need a service upgrade, which is a separate permit and adds 4–6 weeks and $1,500–$3,000 to the timeline and cost.

Plumbing in Franklin kitchens is governed by Wisconsin state code and enforced locally, with particular attention to drain and vent routing. Per IRC P2722 (kitchen sink drains), the drain arm from a sink must slope at least 1/4 inch per 12 inches toward the stack, and the vent must connect within 6 feet of the trap (measured along the drain line). If you're relocating a sink — even if you're moving it just 3 feet — the plumbing code requires a new drain-and-vent drawing showing the trap arm, vent routing, and connection to the main stack. Franklin's plumbing inspector will request this drawing at permit application; omitting it is a common rejection. Additionally, if your kitchen is on a basement level or if the drain runs under the frost line (48 inches in Franklin), the plumbing plan must address frost protection — either the line must slope to a sump or trap or must be insulated below frost depth. Lead-paint disclosure is also mandatory on plumbing permits if the home was built before 1978; the building department will flag this on the permit notice, and you must provide a disclosure form signed by the homeowner before the plumbing inspection can occur. If your kitchen includes a dishwasher, the rough-in must show the drain line and air-gap or high-loop installation to prevent backflow — a detail often missed on first plans.

Range hoods with exterior venting are a major trigger for rejections in Franklin. Per IRC M1502 (kitchen exhaust systems), any range hood that vents to the exterior must have a duct terminating at an exterior wall with a damper-equipped cap; the duct cannot terminate in the attic, crawlspace, or soffit. The city's building inspector will ask for a detail drawing showing the duct route, exterior wall location, cap type, and clearance from any nearby windows or doors (typically 3 feet minimum). If you're venting through an existing wall, the plan must show where the hole is cut and how the duct is sealed around it. Many homeowners overlook this detail or assume a simple kitchen sketch will suffice; the city requires a specific mechanical-system drawing. The duct itself must be sized per IRC Table M1502.1 (typically 6 inches diameter for a standard range hood) and must not be undersized or flex-ducted excessively. If the duct run is longer than 10 feet, you may need a larger-diameter duct or a booster fan; the mechanical contractor submitting the permit must size it correctly. If you're replacing an existing range hood with a new model that vents differently, even if it's on the same exterior wall, the city treats it as a new duct install and requires updated mechanical drawings.

Load-bearing wall removal in a kitchen is rare but catastrophic if done wrong, and Franklin enforces engineering requirements strictly. If you're opening up a wall between the kitchen and dining room or living room, the plumbing inspector will first determine if the wall is load-bearing (typically it is, because it sits perpendicular to floor joists or carries an upper floor). Per IRC R602.7 (Beams and Headers), any load-bearing wall removal must be supported by a properly sized beam engineered by a licensed structural engineer in Wisconsin. The city will not approve a kitchen permit with a load-bearing wall removal unless you submit a PE-stamped beam sizing letter and a structural plan. This adds 2–3 weeks and $800–$1,500 to your project cost, but it's mandatory and the city enforces it. Homeowners who attempt to skip this step (removing a wall without a permit, or submitting a generic beam size) face not only stop-work orders but also potential liability if the wall collapses. Franklin's building inspector will also inspect the beam installation, checking for proper bearing, flashing, and connection to the remaining structure.

Three Franklin kitchen remodel (full) scenarios

Why Franklin's electrical inspector flags kitchen circuits on first submission

The City of Franklin Building Department's electrical inspector operates under Wisconsin Electrical Code (adopted from NEC 2020 edition as of 2024), and the kitchen small-appliance circuit rule is a top-three rejection reason. Per NEC 210.11(C)(1) and 210.52(C), every kitchen must have two or more 20-amp circuits dedicated to countertop receptacles and built-in appliances like dishwashers, microwaves, and garbage disposals. These two circuits cannot be used for any other purpose in the home. Many homeowners and even some contractors assume they can add kitchen receptacles to an existing living-room 15-amp circuit or combine the kitchen outlets with a bedroom circuit; the inspector will immediately reject this on the electrical drawing.

The second major flag is GFCI protection. Per NEC 210.8(A)(6), every receptacle within 6 feet of a sink in a kitchen must be GFCI-protected. Additionally, all countertop receptacles must be GFCI, even if they're 8 feet from the sink. Most homes need 4–6 GFCI receptacles in a full kitchen remodel (sink area, island, peninsula, appliance areas). The inspector will request a drawing that clearly labels which outlets are GFCI and which are standard. Outlets must also be spaced no more than 48 inches apart (measured along the countertop edge). If you have a 10-foot countertop with no outlets shown, the inspector will request you add an outlet every 48 inches. When submitting an electrical drawing to Franklin, include a floor plan with outlet locations dimensioned and labeled 'GFCI' or 'Standard', a panel diagram showing the two 20-amp circuits clearly, and a note that all circuits are 20-amp (not 15-amp). This single document revision eliminates 80% of first-submission rejections.

Franklin's electrical inspector also enforces 240V dedicated circuits for high-draw appliances. If you're installing a gas range, the controls and vent hood fan typically require a 240V circuit (not always, but many modern models do). An electric range obviously requires 240V. A dishwasher on a new installation should have its own 20-amp circuit (shared with the garbage disposal or microwave is acceptable under code, but the inspector prefers dedicated if space allows). When you submit your electrical plan, list every appliance that will be hardwired or hardwired-to-cord, specify its amperage (from the spec sheet), and state whether it requires a dedicated circuit. This clarity prevents the back-and-forth that delays permits.

Plumbing complexity in Franklin kitchens — frost depth, drain sizing, and vent routing

Franklin sits in ASHRAE Climate Zone 6A with a 48-inch frost depth, which directly impacts kitchen plumbing design, particularly for any sink relocation. The Wisconsin State Building Code and local enforcement require that any drain line or water supply line running below 48 inches must either be sloped to daylight (drain away from the foundation), insulated below the frost line, or heat-traced. In a typical kitchen remodel where the sink is relocating from the north wall to an island or peninsula, the drain line may run under concrete slab or through a basement cavity; if it dips below 48 inches without protection, frost heave can crack the fitting or trap. The City of Franklin's plumbing inspector will ask for a detail drawing showing the drain routing and noting whether the line is above or below frost, and if below, how it's protected. This is a local enforcement detail that neighboring cities like Greenfield or Hales Corners may not emphasize as heavily; Franklin's inspector has seen too many mid-winter drain freezes and now requires explicit documentation.

Drain sizing and slope are also critical. Per IRC P2722, the drain arm from a kitchen sink must be a minimum 1.5-inch pipe (for a single sink) and must slope downward at 1/4 inch per 12 inches. The trap must be within 6 feet of the sink opening (measured along the drain line, not straight distance). The vent line connecting to the main stack must be within 6 feet of the trap outlet. If you're relocating a sink 15 feet away, the drain line is long, and the vent routing becomes complex. The plumbing plan must show the trap arm, the vent location, and how it connects to the main stack or a secondary vent. If the sink is on a kitchen island with no wall for a traditional vent, you may need a loop vent (a vent line that goes up, over, and down to connect to the main stack above the sink) or an air-admittance valve (Studor vent). Franklin's plumbing inspector will specify which is acceptable; most prefer traditional vent routing but will approve AAVs if the design is sound.

Lead-paint disclosure is an additional plumbing-permit requirement for pre-1978 homes. If your kitchen was built before 1978 and you're disturbing painted surfaces during remodeling (which you will — demolition alone disturbs paint), Wisconsin and federal law require a lead-hazard disclosure form signed by the homeowner before any construction begins. The City of Franklin Building Department's plumbing permit notice will include a lead-disclosure checklist; you must provide signed confirmation before the plumbing inspection can proceed. Failure to provide this disclosure can delay the project by 2–3 weeks and expose you to liability. This requirement is often overlooked by homeowners but is non-negotiable in Franklin.
