Roseville kitchen remodel permits — the key details

Roseville's Building Department issues one master building permit, but your project automatically triggers three (sometimes four) sub-permits: building, electrical, and plumbing are mandatory; mechanical is required only if you're adding a range hood with exterior ducting. Under Michigan Building Code (MBC) Section 3401, a kitchen is defined as a space with a sink, cooking appliance, and food-prep area, and any alteration to those elements or the spaces around them requires a permit. The permit application requires a detailed site plan (showing the kitchen's location in the home), a floor plan with all cabinet and fixture locations, electrical and plumbing diagrams, and a load-bearing wall analysis (engineer's letter) if you're removing any wall. The City of Roseville's online portal (accessible through the city website) now requires pre-filing a one-page scope-of-work form before you can submit full plans — this step was added in 2023 and catches many applicants off guard. You can download the form from the Building Department's webpage or call to request it by email.

Electrical work in a kitchen is heavily regulated. Per MBC (adopting NEC Article 210), your kitchen must have at least two 20-amp small-appliance branch circuits serving the counter-top areas; these circuits cannot serve lights or non-kitchen receptacles. Counter receptacles must be spaced no more than 48 inches apart (measured horizontally along the counter edge), and every counter-top receptacle must be GFCI-protected — not AFCI, not a combination, but GFCI, installed at the outlet or at the breaker. The kitchen sink area and any island must also have GFCI protection. Many homeowners and even some contractors miss this: if your kitchen has an island or peninsula, the island must have at least one receptacle, and it counts toward the 48-inch spacing rule. The electrical permit ($200–$400 in Roseville, typically 1-2% of the electrical work valuation) covers the rough-in inspection (before drywall), a trim-out inspection (after drywall and before fixtures), and a final inspection. The electrical inspector will want to see the panel schedule (showing breaker assignment and amperage) on your electrical plan.

Plumbing relocations are common in kitchen remodels and require a separate plumbing permit ($150–$300 in Roseville). If you're moving the sink location, you must show on the plumbing plan the trap location, the trap arm (the sloped drain line from sink to main stack), and the vent connection. Michigan Building Code Section 2722 requires a kitchen sink trap to be at least 6 inches below the rim and no more than 30 inches below; the trap arm must slope at a minimum 1/4 inch per foot and must be no longer than 3.5 feet (or 5 feet with a larger-diameter trap). If your sink is more than 5 feet from the main vent stack, you will need a secondary vent (revent) or a larger-diameter horizontal vent, which adds cost ($500–$1,500 in labor). The plumbing plan must also show the location of water supply lines (hot and cold), and if you're adding a dishwasher or island sink, those must be tied into the existing supply and drain. If the home was built before 1978, the plumbing permit application requires a lead-paint disclosure; the Building Department will provide the form, and you must have the homeowner sign it before work begins.

Load-bearing wall removals are the single most expensive part of a kitchen remodel and require structural engineering. If you're removing a wall that spans the width of the kitchen or runs perpendicular to floor joists, assume it is load-bearing unless a qualified engineer verifies otherwise. The Michigan Building Code (MBC Section 602) requires that any wall removal be accompanied by a beam-design letter from a licensed Michigan engineer (PE). The letter must specify the beam size, material (wood, steel, engineered lumber), bearing requirements, and any temporary bracing or joist-support details. The Building Department will not issue a permit without this letter. Beam installation typically requires temporary supports during construction, and the MBC requires a temporary-bracing plan to be on-site and reviewed before framing begins. If the wall supports a second story or roof load, the beam cost can run $3,000–$8,000 (materials + labor); if it's a single-story load, $1,500–$3,000. The Building Department's Building Inspector will schedule a framing inspection before you drywall; they will verify beam size, bearing, and support.

Range-hood venting is often overlooked and is a common cause of permit rejection. If you are installing a range hood with exterior ducting (the most common setup), the mechanical plan must show the duct diameter, the exterior termination point, and a cap detail. Roseville's Building Department requires that the duct terminate through an exterior wall or roof, not into an attic or basement; the cap must be a mushroom or damper cap rated for ductwork (not a simple screen). If you are ducting through an exterior wall in the south part of Roseville (42-inch frost depth), the duct penetration must be sealed and insulated to prevent condensation and freezing. If the duct terminates on a roof, the penetration must be sealed with flashing and caulk rated for high-temperature exposure. Many kitchens do not have a hood or have a recirculating (ductless) hood, which does not require a mechanical permit. However, if you are upgrading from recirculating to vented, you will need a mechanical permit. The cost of a mechanical permit in Roseville is typically $100–$200 and is often bundled with the electrical permit if the same contractor is pulling both.

Three Roseville kitchen remodel (full) scenarios

Roseville's frost depth and plumbing penetrations: what you need to know

Roseville straddles two frost-depth zones: the southern part of the city (south of 13 Mile Road) has a frost depth of 42 inches, while the northern part is 48 inches or deeper. If you are relocating plumbing or installing a new sink on an exterior wall or island near an exterior wall, the water supply and drain lines must be protected from freezing. Michigan Building Code Section 2307 requires that any water supply line in an unheated space (basement, crawlspace, attic) be insulated with at least 1 inch of foam or equivalent; drain lines should also be insulated if they run outside the thermal envelope. If your home is in the southern frost zone and you are moving the sink to a location farther from the main stack than the original sink, you may need to run the vent line deeper (closer to the frost line) to avoid condensation freeze-up in the vent. The plumbing inspector will ask about insulation during the rough-plumbing inspection; if it's inadequate, you will be asked to add foam wrap or reroute the line.

If you are doing any foundation work (e.g., digging to run a new drain line through the basement floor) in the southern zone, you will encounter glacial till — a dense, clay-and-gravel mix. This makes digging harder and more expensive. If you are in the northern zone, the soil tends to be sandier and easier to dig but may drain faster, which can affect sump-pump placement if you are adding a wet-vent or revent below the basement rim. The Building Department's plumbing permit checklist will flag frost depth; make sure your plumber knows your exact address so they can confirm the zone and plan accordingly.

For islands or peninsulas with sinks, the vent challenge is unique to kitchen remodels. If your island is more than 5 feet from the main vent stack, the trap arm will be too long (MBC Section 2722 limits trap arm to 3.5 feet unless you use a larger-diameter trap or secondary vent). A secondary vent (revent) typically runs up the wall behind the island and ties into the main vent stack or roof vent. This adds $500–$1,500 in plumbing cost. The plumbing inspector will require the vent to be visible on the rough-plumbing inspection before drywall; if you drywall over it without inspection approval, the inspector will order it removed and re-inspected.

Roseville's electrical inspector and kitchen-counter receptacle spacing: why it fails inspections

Roseville's electrical inspector is known for being strict about NEC Article 210 (general-purpose branch circuits and outlets) compliance, particularly in kitchens. The rule is simple but often missed: counter-top receptacles must be spaced no more than 48 inches apart (measured horizontally along the counter edge), and every one must be GFCI-protected. What catches contractors is the 48-inch rule. If you have a 10-foot counter with two receptacles spaced 5 feet apart, you fail — you need at least three receptacles (roughly 3 feet apart). Many first-time remodelers install one or two receptacles 'in the middle' of a long counter and assume it's enough; it's not. The inspector will red-tag the job and require you to add outlets. An electrician can usually add a new outlet by running Romex from an existing nearby circuit, costing $150–$300 per outlet.

The second common failure is GFCI placement. The code requires GFCI protection for all counter-top receptacles, but it can be provided either at the outlet itself (a GFCI receptacle) or at the breaker (a GFCI breaker protecting the entire circuit). Many contractors opt for the cheaper route — a GFCI breaker protecting both the 20-amp small-appliance circuits. However, if you do this, the Roseville inspector may ask to see a label on the breaker indicating 'GFCI PROTECTED' and a note on the electrical plan showing the GFCI assignment. If you use GFCI receptacles instead, each one must be labeled 'GFCI' with a test/reset button visible. The inspector will physically press the test button on a few to verify they work.

For islands and peninsulas, the inspector also verifies that the island has at least one receptacle and that it is spaced within the 48-inch rule relative to the counter on either side. An island with a 4-foot depth and two 10-foot sides typically requires 3-4 receptacles (one on each long side, one on the short side toward the range, etc.). The electrical permit must include a detailed counter-layout drawing showing every receptacle location with dimensions. If you don't provide this, the Building Department will ask for it before plan review is complete.

Lead time for electrical rough-in inspection is typically 3-5 business days after you notify the city that framing is complete and Romex is run. The inspector wants to see the panel schedule, the breaker labels, the GFCI receptacle placement, and the vent-hood wiring (if applicable). If you have hired an electrician, they usually handle the permit and inspection coordination; if you are owner-builder, you must call the Building Department to schedule.
