Auburn Hills kitchen remodel permits — the key details

Auburn Hills adopted the 2015 International Building Code as its baseline, with amendments published in the City of Auburn Hills Building Ordinance (Chapter 25). The city's Building Department interprets these rules consistently and publishes an FAQ on its website addressing the most common kitchen-permit questions, including the two-circuit electrical requirement and GFCI spacing rule. Under IRC E3702, every kitchen must have at least two 20-ampere small-appliance branch circuits serving countertop receptacles; most kitchens need four to six circuits once you account for the refrigerator (dedicated 15 or 20 amp), microwave (often 20 amp), dishwasher (usually 15 amp on a shared circuit with disposal), and range/cooktop (40-60 amp for electric, 15 amp for gas). Auburn Hills' plan-review process requires a one-line electrical diagram showing all circuits, breaker sizes, and GFCI locations; missing this drawing triggers a rejection, adding 2-3 weeks to your timeline. The city's electrical inspector will also verify that all countertop receptacles are within 48 inches of the appliance location (measured along the countertop edge) per NEC 210.52(C), and that all countertop and island outlets are GFCI-protected — a common miss on DIY designs.

Plumbing changes in a kitchen remodel are equally scrutinized. IRC P2722 governs kitchen sink drains, requiring a minimum 1.25-inch trap arm with proper slope (1/4 inch drop per foot of run, but not more than 1/2 inch per foot) and connection to a properly vented stack or loop-vent. Auburn Hills' plumbing inspector will ask for a roughing-in drawing showing the trap location, vent routing, and connection to the main drain stack; if your kitchen is far from the stack (e.g., moving the sink to an island), you may need a wet vent or an individual vent loop, which adds complexity and cost. If you're relocating the sink across the room or to an island, the city requires a separate plumbing permit application, and the inspector will mark up your drawing if the trap arm is too long, the slope is wrong, or the vent is inadequate. Lead-based paint is a non-negotiable requirement: if your home was built before 1978, you must file a Lead-Based Paint Disclosure with the City and complete a Risk Assessment before any work begins; failure to comply can result in federal fines up to $16,000 and criminal liability. Auburn Hills Building Department staff will ask for proof of this disclosure at permit issuance, and the contractor or owner must sign an acknowledgment form.

Gas-line modifications in a kitchen remodel trigger a separate mechanical permit in Auburn Hills. If you're replacing an existing gas cooktop or adding a new gas range, and the gas line is already in place at the right location, you typically do not need a mechanical permit — just a connection inspection by a licensed plumber or gas fitter. However, if you're moving the gas line, installing a new takeoff from the main line, or adding a second gas appliance, Auburn Hills requires a mechanical permit, a gas-line pressure test, and a final inspection. IRC G2406 governs gas-appliance connections, requiring flexible stainless-steel tubing (not copper or black iron in modern code) with a manual shutoff valve within 6 inches of the appliance. The city's inspector will verify the line size (typically 3/8-inch for a single cooktop, 1/2-inch if multiple appliances share the line), the pressure rating, and the shutoff location. If your home has an old black-iron gas line, the city may require you to replace it with approved tubing as part of the permit; this is especially common in homes built before 2000 and can add $800–$2,000 to your project cost.

Load-bearing wall removal is a critical fork in the road for kitchen remodels, and Auburn Hills does not waive the engineering requirement. If you're removing any wall between the kitchen and an adjacent room (to open the kitchen to a dining or living area), the city requires a structural engineer's letter confirming that the wall is non-load-bearing, or a sealed beam-design calculation showing a properly sized beam, posts, footings, and connections if the wall is load-bearing. The engineer's letter must be submitted with the building-permit application; Auburn Hills will not issue a permit without it. This adds 1-2 weeks to the timeline and costs $300–$800 for the engineer's review and letter. If the wall is load-bearing, the beam and support design can cost $1,500–$3,000 in engineering fees alone, and installation of the beam, posts, and footings can add another $5,000–$15,000 to your project. The city's building inspector will perform a frame inspection before drywall is closed and a final inspection after everything is sealed; skipping the engineer or misrepresenting a wall as non-load-bearing is a major violation and can result in a stop-work order.

Auburn Hills requires three separate permit applications and inspection sequences: building, plumbing, and electrical. Each trade gets its own permit number, fee, and inspector. The building permit covers framing (including wall removal and any structural changes), window/door openings, and general construction. The plumbing permit covers drain, waste, and vent (DWV) rough-in, sink relocation, and gas-line modifications. The electrical permit covers all new circuits, receptacles, lighting, and GFCI installations. You can file all three applications at once through the city's online portal, but each will be reviewed separately, and you'll schedule inspections in sequence: rough plumbing and electrical first (before drywall), then framing and structural (if applicable), then final inspections for each trade. Most kitchens take 3-6 weeks for plan review and 2-4 weeks for final inspections, assuming no rejections or re-inspections. Auburn Hills charges a permit fee based on the total project valuation (typically 1.5% of the estimated cost for building, plumbing, and electrical combined), so a $50,000 kitchen remodel would generate $200–$300 in combined permit fees (roughly $80–$100 for building, $60–$100 for plumbing, $60–$100 for electrical). The city's online portal allows you to upload drawings, pay fees, and check inspection status; you can also call the Building Department at the main city hall number to schedule inspections or ask questions.

Three Auburn Hills kitchen remodel (full) scenarios

The two-circuit electrical requirement and countertop-receptacle spacing in Auburn Hills kitchens

Auburn Hills enforces IRC E3702, which mandates at least two separate 20-ampere small-appliance branch circuits for kitchen countertops. This rule exists because the average kitchen now has multiple countertop appliances (toaster, coffee maker, blender, food processor, mixer, instant pot, air fryer) that can each draw 10-15 amps, and a single 15-amp circuit would trip constantly. The city's electrical inspector will ask to see a one-line diagram showing each circuit, its amperage, the breaker size, and which outlets it serves; a common rejection is a plan that shows only one circuit feeding all countertop outlets, or two circuits that are not dedicated (meaning they also feed other areas of the house).

Countertop receptacle spacing is governed by NEC 210.52(C), which requires that no point on a countertop be more than 48 inches (measured horizontally along the countertop edge) from a receptacle. Auburn Hills interprets this strictly: if your countertop is 10 feet long, you need at least three receptacles (at 0 feet, 4 feet, and 8 feet, for example). Island countertops, peninsulas, and sink backsplash areas all count. The electrical inspector will measure the distance and mark rejections on the plan if spacing is wrong; this is not negotiable and causes many plan-review delays. Additionally, all countertop and island receptacles must be GFCI-protected per NEC 210.8(A)(6) — either by installing GFCI outlets or GFCI breakers. A common miss is installing standard outlets and assuming the GFCI breaker will protect them; the inspector will reject this and require either individual GFCI outlets or a GFCI breaker clearly labeled on the one-line diagram.

A refrigerator outlet (typically at the end of a countertop or in a corner) does not count toward the spacing requirement but must be on its own dedicated 15 or 20-amp circuit and cannot share the circuit with any other outlet. If your current kitchen has the fridge on a shared circuit with other countertop outlets, Auburn Hills will require you to separate it during the remodel. This often means adding a new circuit breaker and running a new wire from the panel to the fridge location, adding $300–$800 to the electrical cost.

Load-bearing wall removal and Auburn Hills' structural engineering requirement

Auburn Hills does not grant exemptions or waivers for load-bearing wall removal in kitchen remodels. If you want to open the kitchen to an adjacent room by removing a wall, the city requires a sealed structural engineer's letter or beam-design calculation before the permit issues. The engineer must review your home's framing, determine whether the wall is load-bearing (by examining joist direction, roof load, foundation support, and any posts or beams below the wall), and specify the replacement beam size, material, post locations, and footing requirements. A non-load-bearing wall removal requires only the engineer's letter stating so (typically one page, costs $300–$500); a load-bearing wall removal requires a full structural design with calculations, drawings, and specifications (10-20 pages, costs $800–$2,000).

Most kitchens in Auburn Hills are in residential subdivisions built between 1960 and 2010, and a significant portion have load-bearing walls between the kitchen and dining or living room — the wall often sits over the basement or crawl-space foundation and carries the roof load. If your engineer recommends a beam, you will need to choose between a steel I-beam (typically 8 to 12 inches deep, spans 12-20 feet, costs $800–$2,000 for material and installation) or an engineered lumber beam like an LVL or microlam (typically 14-16 inches deep, similar cost). Steel beams require posts and footings at each end, adding to the installation cost. Posts must sit on proper footings (concrete piers, frost-protected to 42 inches in Auburn Hills' frost-depth zone, if the foundation is not nearby). Many homeowners underestimate this cost and discover at permit time that they need a $5,000–$15,000 structural upgrade. Auburn Hills' building inspector will perform a rough-frame inspection to verify that the beam is properly installed, the posts are plumb, and the footings are adequate before drywall is hung; skipping this inspection is not permitted.

One final consideration: if the wall being removed contains plumbing, electrical, or HVAC ducts, those utilities must be rerouted before the wall is demolished. A kitchen wall often contains drain lines (if the sink is on that wall), supply lines, gas lines, electrical circuits, and maybe a ductwork vent. Rerouting these utilities can add $2,000–$5,000 to the project and 1-2 weeks to the timeline. Your plumbing and electrical plans must show the rerouted utilities; Auburn Hills will not approve the building permit if the utility rerouting is incomplete on the drawings.
