Do I need a permit in Clawson, MI?
Clawson is a compact city in Oakland County, Michigan, with a building permit system that follows Michigan's Uniform Building Code (based on the 2015 IBC with state amendments). The City of Clawson Building Department handles all residential permits — from decks and fences to additions and mechanical work. Because Clawson sits in climate zones 5A and 6A (with a 42-inch frost depth, notably deeper than the national default of 36 inches), footing and foundation requirements for decks, sheds, and additions reflect that reality. Michigan law allows owner-builders to pull permits for owner-occupied residential work without a contractor's license, which means you can file most residential permits yourself — but the city still inspects to code, and some trades (electrical, plumbing) may require licensed subcontractors depending on scope. The permit office is accessible by phone and in person at City Hall during standard business hours; as of this writing, Clawson does not offer fully online filing, though you can confirm current portal availability by contacting the building department directly.
What's specific to Clawson permits
Clawson's 42-inch frost depth is the single biggest local variable. Deck footings, shed foundations, and any structural element bearing on soil must bottom out below 42 inches to avoid frost heave in winter. This is 6 inches deeper than the IRC baseline and reflects glacial-till soils common to the region. If you're building a deck or shed, plan for deeper holes — and know that the inspection will require evidence (footing-depth photos or inspection during construction) that you've hit that depth.
Michigan's Uniform Building Code adoption means Clawson enforces the 2015 IBC with state amendments. This affects electrical work (Michigan uses the 2014 NEC, not the 2020), mechanical systems, and energy code. If you're hiring subs (electrician, HVAC, plumber), they should be familiar with Michigan-specific amendments, not just the base IBC. Owner-builders can pull residential permits, but if the work triggers electrical, plumbing, or mechanical scope, the city will require licensed contractors or subpermits for those trades.
Permit-office workflow: Clawson processes most applications in person at City Hall. You'll need a completed permit application, site plan showing lot lines and structure placement, and a description of the work. Fees vary by project type and valuation; typical residential permits run $50–$250 for straightforward work (deck, fence, shed) and higher for additions or renovations (usually 1–2% of project cost). Plan-review time averages 3–5 business days for routine projects; complex additions may take 1–2 weeks.
Common rejection reasons in Clawson: missing frost-depth documentation (applicants assume 36 inches), no property-line survey or site plan showing setback compliance, and incomplete electrical scope (applicants don't realize a sub-panel or outdoor outlet needs a licensed electrician's involvement). Second most common: applicants filing for 'minor' work like a deck or carport that turns out to encroach on a setback or easement. Run a quick lot-line check before filing; the city assessor's office can help.
Seasonal note: Clawson's frost-heave risk peaks October through April. If you're planning foundation or footing work, spring through early fall is ideal for inspection access and completion. Winter inspections are harder (frozen ground, limited digging windows) and can delay projects. Schedule new construction or major footer work for May through September when possible.

Michigan context for Clawson permits
Michigan requires all building permits to comply with the Michigan Uniform Building Code (MUBC), which adopts the 2015 International Building Code with state-specific amendments and stricter energy code. The state allows owner-builders to pull permits for owner-occupied residential work without a contractor's license — a significant advantage for DIY projects. However, Michigan also requires specific trades to be licensed: electricians (for all but basic lighting circuits and standard outlet work), plumbers (for new water and drain lines), and HVAC contractors (for new equipment). If you're doing the structural or carpentry work yourself but need an electrician for a new circuit or outlet, the electrician typically files a subpermit under your residential permit. Michigan's 2014 NEC adoption (not the 2020) also means electrical design must follow that edition — most licensed electricians in the state know this, but it's worth confirming if you're using someone from outside Michigan. The state also enforces Michigan's Energy Code, which may affect insulation, window, and HVAC specs for additions and renovations. Frost depth varies across the state; Clawson's 42-inch requirement is typical for Oakland County and the southern Lower Peninsula. The state provides a frost-depth map by county, and the building department can confirm the exact requirement for your address.
Common questions
Do I need a permit for a deck in Clawson?
Yes. Any deck (attached or freestanding) in Clawson requires a permit. The threshold is a deck as defined in the Michigan Uniform Building Code — typically any raised platform used for seating or access. Because Clawson's frost depth is 42 inches, footings must bottom out below 42 inches. You'll need a site plan showing lot lines, setback distances, and footing placement. Most deck permits run $75–$150 and process in 5–7 business days.
Can I pull my own permit as an owner-builder in Clawson?
Yes, Michigan allows owner-builders to pull permits for owner-occupied residential work without a contractor's license. You can file the application yourself at City Hall. However, if your project includes electrical work beyond standard outlets and switches, or any new plumbing or HVAC, you'll need to hire a licensed sub for that trade — and the subcontractor typically pulls their own subpermit under your main permit. The building department can clarify what scope requires a sub license for your specific project.
What's the frost depth for footings in Clawson?
42 inches. Clawson's frost depth is deeper than the national IRC baseline of 36 inches because of glacial soils and the Upper Midwest climate zone. Any footing — deck, shed, fence post, or foundation — must bottom out below 42 inches to avoid frost heave. The inspection will require proof: footing-depth photos during construction or measured hole depth before pouring. This is the #1 local requirement applicants miss.
How much do permits cost in Clawson?
Most simple residential permits (deck, fence, shed, roof replacement) run $50–$250. Larger projects like additions or renovations typically cost 1–2% of project valuation. Call the Building Department with your project scope and estimated cost, and they'll give you a specific fee quote. There are no surprise add-ons; the fee is usually all-inclusive of plan review and first inspection.
Do I need a permit for a fence in Clawson?
Yes. Fences over 4 feet require a permit in Clawson. You'll need to show lot lines and setback distances (fences must comply with local zoning setback rules, typically 5–10 feet from front property line depending on district). The permit cost is typically $75–$100, and review averages 3–5 days. If the fence is near a corner lot or public utility easement, confirm setback compliance with the city before filing.
What code edition does Clawson use?
Clawson adopts the Michigan Uniform Building Code, based on the 2015 International Building Code with Michigan state amendments. This affects electrical work (Michigan uses the 2014 NEC, not the 2020), energy code (Michigan's is stricter), and mechanical systems. If you're hiring contractors, confirm they're familiar with the 2015 IBC and 2014 NEC — not newer editions that might have different rules.
Do I need a permit for a shed or detached structure in Clawson?
Yes, if the shed is over a certain size (typically 100–120 square feet, depending on the code edition). Any shed with a foundation or on footings definitely requires a permit. You'll need a site plan showing lot lines, setback distances, and footing placement. Remember: footings must go 42 inches deep. Most shed permits run $75–$150.
How long does permit review take in Clawson?
Routine permits (deck, fence, shed, roof) average 3–5 business days. Complex projects (additions, renovations, mechanical work) may take 1–2 weeks. If the reviewer finds issues (missing documentation, setback problems, footing depth concerns), they'll send an email or call with a correction list, and you'll resubmit. Processing resumes once corrections are received. Over-the-counter permits approved on the same day are rare unless the application is very simple and the department is not busy.
Can I file a permit online in Clawson?
As of this writing, Clawson does not offer fully online permit filing. You'll need to submit applications in person at City Hall during business hours (Monday–Friday, 8 AM–5 PM). Contact the Building Department to confirm if e-filing or an online portal has been added since this was written.
