Do I need a permit in Auburn Hills, Michigan?
Auburn Hills sits in Oakland County on the border between climate zones 5A and 6A, which matters for deck footings and foundation depth requirements. The city adopted the 2015 Michigan Building Code (based on the 2015 IBC), which means you're working with a code edition that's now about a decade old — good news if you're pulling old building permits as reference, less good if you're looking at brand-new products or methods.
The Auburn Hills Building Department handles all residential permits. Most homeowners don't call until they're already halfway through a project, which costs time and money. A 15-minute phone call before you start saves nearly all of that. The city processes routine permits (fences, sheds, decks) over-the-counter in most cases. More complex work (additions, electrical, plumbing, HVAC) requires plan review and formal submission.
Auburn Hills' frost depth is 42 inches across most of the city. If you're in the southern part (climate zone 5A), you're at 42 inches. Northern areas (5A-to-6A transition) may see 48 inches in some references, but 42 inches is the safe local standard. That's deeper than the IRC minimum for zone 5 (36 inches), so your deck posts, shed foundations, and retaining walls all need to go deeper than the code book's baseline numbers. Glacial till and sandy soil north of M-59 mean different drainage and frost-heave patterns — important if you're installing a fence or building a patio.

What's specific to Auburn Hills permits
Auburn Hills uses the 2015 Michigan Building Code. Most of the state adopted the same edition, which means you can reference the IRC/IBC directly for code citations — the state simply added amendments on top. The key Auburn Hills twist is the frost-depth requirement: the city enforces a 42-inch footing depth, not the 36 inches shown in the IRC for zone 5. This applies to any structure with a permanent foundation — decks, sheds, freestanding carports, pergolas with footings. Homeowners who dig to 36 inches and fail inspection end up paying to dig deeper. Start at 42.
The city's zoning code is separate from the building code. Setbacks, lot coverage, height limits, and whether you can build in a floodplain or wetland are zoning questions. A permit office can tell you if a permit is required by building code, but you still need to check zoning separately — ideally before you file. A deck might be fully code-compliant but violate a setback, and the building department won't catch that until plan review. Call the City of Auburn Hills Planning Department (separate from Building) or ask the building department to cross-check your project against the zoning ordinance before you submit.
Auburn Hills does not currently offer a fully online permit portal for residential work. You can submit permits by mail or in person at city hall. The city does not have an over-the-counter window for all permit types — some simple projects (small sheds, fences) may be processed faster, but it's worth confirming by phone before you show up. Call the Building Department directly to ask if your specific project qualifies for same-day or next-day processing. Email submission may be available; ask when you call.
Electrical work, plumbing, and HVAC must be done by licensed contractors in Michigan. Owner-builders can do structural work (framing, decking, masonry) on owner-occupied property, but you cannot pull an electrical or plumbing permit as an unlicensed homeowner. A licensed electrician must file and pull the electrical subpermit separately. This is state law, not Auburn Hills-specific, but it catches a lot of homeowners off-guard. If you're planning a kitchen or bathroom remodel, budget for a licensed plumber and electrician — you can do the framing and drywall, but not the trades.
The city is part of Oakland County, which operates a joint permit processing system for some project types. Regional floodplain and wetland reviews route through the county. If your property is near a wetland, creek, or floodplain, the county may impose an additional 2–3 week review period. Auburn Hills is north of the Detroit area and sits on glacial terrain with seasonal drainage issues, so wetland setbacks are common. Check the FEMA floodplain map and Michigan wetland GIS before you plan a basement or foundation work.
Most common Auburn Hills permit projects
These are the projects Auburn Hills homeowners ask about most. Click through for local fee ranges, what the inspectors will actually check, and what disqualifies you from a permit.
Deck or patio
Decks over 30 inches high or attached to the house always require a permit. The critical detail for Auburn Hills: footings must reach 42 inches below grade. Frost heave is real in Michigan winters. Most rejections stem from shallow footings or inadequate ledger-board flashing where the deck attaches to the house.
Shed or storage building
Sheds under 200 square feet with a permanent foundation typically need a permit in Auburn Hills, depending on setbacks. Structures on a concrete slab may process faster than those on posts. The 42-inch frost depth applies here too.
Fence
Residential fences over 4 feet, all corner-lot fences (regardless of height), and any fence less than 3 feet from a property line require a permit in most Oakland County jurisdictions. Auburn Hills typically requires a permit for height-restricted fences and all pool barriers. Verify the exact height threshold and setback rule by calling the Building Department — local zoning can be stricter than the base code.
Addition or remodel
Any room addition, kitchen or bathroom remodel, or basement finishing requires a permit. Electrical and plumbing work must be done by licensed contractors. Plan review typically takes 2–3 weeks. Setback and lot-coverage compliance are common rejection reasons in Auburn Hills' residential zones.
Roof replacement
Michigan requires a permit for all roof replacements. The city inspects roofing for code-compliant fastening, ventilation, and flashing. Reroofing over existing layers may be allowed once; a second layer usually triggers removal of the old roof before replacement.

Michigan context for Auburn Hills permits
Michigan is a home-rule state, meaning cities adopt and enforce the state's model codes but can impose stricter local rules. Auburn Hills adopted the 2015 Michigan Building Code, which is the 2015 IBC with state-specific amendments. The most important amendments affect wind resistance, roof design, and foundation requirements in snow-load and frost-depth zones. Michigan law (MCL 125.1506) allows owner-builders to do structural work on owner-occupied property but explicitly prohibits unlicensed individuals from doing electrical, plumbing, mechanical, or gas-line work. A licensed contractor must pull those permits.
Michigan also has strict wetland and floodplain rules enforced by the Department of Environment, Great Lakes and Energy (EGLE). If your property is within 500 feet of a wetland or in a floodplain, you'll need state permits in addition to local ones. Auburn Hills is on glacial terrain with seasonal high-water tables, so this is common north and east of downtown. Check the Michigan wetland GIS map and FEMA floodplain map before you apply — the city won't issue a building permit if state wetland permits are required and haven't been filed.
Roof replacements in Michigan require a permit and inspection, unlike some states. The 2015 code requires roof-over inspections when adding shingles to existing layers; a second layer usually means removal of the old roof first. Snow load is a factor in roof design — Auburn Hills averages 35–45 inches of snow annually, which affects rafter spacing and roof pitch requirements.
Common questions
Do I need a permit for a small shed or tool storage?
Sheds with a permanent foundation (concrete pad or footing) over 120–150 square feet typically require a permit in Auburn Hills, depending on setbacks and zoning. Sheds under 120 square feet on a gravel pad may be exempt, but zoning often restricts them in front yards or within a certain distance of property lines. The safest move is a photo and a phone call to the Building Department before you buy the kit. If it's permitted, footings must reach 42 inches below grade.
What's the frost depth, and why does it matter?
Auburn Hills' frost depth is 42 inches. Frost depth is the depth at which soil freezes in winter. Concrete footings, deck posts, fence posts, and shed foundations must be installed below the frost line, or frost heave will push them up in spring and crack or shift the structure. The IRC calls for 36 inches in zone 5, but Auburn Hills enforces 42 inches — dig to that depth. Northern Michigan sites can go deeper; call the Building Department if you're unsure.
Can I do electrical work myself on a permit I pull?
No. Michigan law prohibits unlicensed individuals from doing electrical work, even as an owner-builder. A licensed electrician must pull the electrical subpermit and do the work or supervise it. The same applies to plumbing and HVAC. You can do framing, drywall, painting, and decking yourself, but all trades work must be licensed. Budget for a licensed contractor's time.
What's the typical permit fee in Auburn Hills?
Auburn Hills' permit fees are based on project valuation. A rough guide: decks run $50–$150, sheds $75–$200, additions and remodels $200–$800 or more depending on scope. Electrical and plumbing subpermits add $50–$100 each. The city calculates fees as a percentage of estimated project cost, typically 1.5–2%. Call the Building Department with a description of your project and estimated cost, and they'll quote you a fee. Fees must be paid before permit issuance.
How long does plan review take?
Routine permits (fences, small sheds) may be issued over-the-counter same-day or next-day. Structural projects (decks, additions, basements) typically need plan review, which takes 2–3 weeks in Auburn Hills. Wetland or floodplain reviews add another 1–2 weeks. Always apply at least a month before you plan to start, longer if your property is near a wetland or in a special regulatory area.
Do I need a variance for a corner-lot fence?
Corner-lot sight-triangle rules are strict in Michigan. Most corner lots cannot have fences or shrubs taller than 3 feet in the sight triangle. This is a zoning rule, not a building code rule, and variances are hard to get. If you're on a corner, check the zoning ordinance or call the Planning Department before you design your fence. A variance can cost $500+ in application fees and takes 4–6 weeks.
What if I build without a permit?
Building without a permit can trigger fines ($100–$500 per day in some Michigan municipalities), orders to remove the structure, and title problems when you sell. Unpermitted work won't pass inspection, and the city can force removal at your cost. Permits also protect you: a permitted job has been inspected for safety and code compliance. Skip the permit and you're liable if someone is injured or property is damaged.
Start your Auburn Hills permit project
Before you call the Building Department or file an application, know your project's scope, footprint, and rough cost estimate. Grab a tape measure, take photos of your property and the area where you'll build, and sketch where the new structure will sit relative to property lines and existing structures. Have your address and lot number ready. Call the Auburn Hills Building Department at 248-370-9400 (or your verified local number) and describe your project. They'll tell you if a permit is required, what it costs, what documents you need, and how long review takes. Most of the time, that conversation saves you weeks of frustration.
