§ Detroit fast facts

QUICK ANSWERS.

Do I need a permit for a deck or patio slab in Detroit?

Yes. The City of Detroit BSEED requires a building permit for any deck attached to a dwelling and for flatwork in or adjacent to the public right-of-way. Freestanding patios on private property may be exempt depending on size, but you should confirm with BSEED before starting work. Unpermitted decks can create liability and complicate property sales.

§ Built for Detroit

LOCAL FACTS.

MICHIGAN FROST DEPTH REQUIREMENT FOR DECK FOOTINGS.

42 inches minimum per Michigan Residential Code R403.1.4.1 — footings for attached decks in Detroit must extend below this depth, adding excavation and concrete cost compared to warmer-climate markets.

AVERAGE DECK CARPENTER LABOR RATE — DETROIT METRO.

Deck and general carpentry labor in the Detroit metro area runs approximately $28–$38 per hour for journeyman-level tradespeople, based on Southeast Michigan prevailing wage data and regional contractor surveys (2023–2024).

CITY OF DETROIT BSEED DECK PERMIT FEE.

Residential deck permits issued by Detroit's Buildings, Safety Engineering and Environmental Department (BSEED) typically range from $150 to $350 depending on project valuation, with plan review adding 2–4 weeks to the project timeline.

FREEZE-THAW CYCLE IMPACT ON DETROIT FLATWORK.

Detroit averages approximately 136 days per year at or below freezing, one of the highest counts among major Midwest metros. ACI 318 Table 19.3.3 requires concrete mix designs with a maximum 0.45 water-cement ratio and air entrainment for severe freeze-thaw exposure — specs that must be reflected in your material cost line items.

§ Why other (decks, flatwork) pros in Detroit use Estimate.Pro

THE BID ENGINE.

## Estimating Decks and Flatwork in Detroit Takes More Than a Spreadsheet Detroit's climate does real damage to outdoor concrete and wood structures. Freeze-thaw cycles — Detroit averages 136 freezing days per year — crack flatwork, heave footings, and rot joists faster than in warmer markets. Your bids have to account for that reality: deeper frost footings (minimum 42 inches per Michigan Residential Code R403.1.4.1), pressure-treated lumber at ground contact, and concrete mixes rated for high freeze-thaw exposure per ACI 318 Table 19.3.3. If your estimate doesn't price those line items correctly, you eat the margin on the back end. ## What Makes Detroit Deck and Flatwork Estimating Different **Permit requirements add real cost.** The City of Detroit Buildings, Safety Engineering and Environmental Department (BSEED) requires permits for decks attached to a dwelling and for flatwork in the right-of-way. Permit timelines in Detroit can run 2–4 weeks for residential deck permits, and inspections require specific footing-depth documentation. That waiting period needs to show up in your project schedule and in your overhead recovery. **Material costs fluctuate with local supply chains.** Pressure-treated lumber, concrete, and composite decking prices in the Southeast Michigan market track closely with Great Lakes regional distribution hubs. Locking in your material cost workspace in Estimate.Pro lets you update unit prices when your supplier changes them — and every estimate you build reflects current numbers, not last quarter's. **Labor rates in Detroit are specific.** Deck carpentry and flatwork labor in the metro runs at rates that differ from statewide averages. Underbidding labor because you're using national benchmarks is one of the fastest ways to lose money on a Detroit job. **Driveways and flatwork are high-volume work here.** Detroit's older housing stock — much of it built pre-1960 — means a large pool of replacement driveways, aprons, and patio slabs. Contractors who can turn bids fast on flatwork win the volume. Contractors who spend two hours building a spreadsheet for a 400-square-foot driveway don't. ## How Estimate.Pro Works for Deck and Flatwork Contractors You walk the site. You open the app. Estimate.Pro guides you through a structured scope-of-work walkthrough designed for the trades — including decks and flatwork. AR measurement tools on supported devices let you capture dimensions on-site. Photos and camera measurements are flagged as estimates so you know exactly what's confirmed and what needs verification. The AI takes your walkthrough inputs and produces a line-item scope of work. You review it, adjust for Detroit-specific conditions — frost depth, concrete mix spec, permit allowance — and send. Median time from walkthrough start to sendable bid: 8 minutes. Your saved material cost workspace holds your current lumber, concrete, composite decking, gravel base, and hardware pricing. Update it when your supplier changes the sheet. Every new estimate pulls live from that workspace. ## Plans That Fit Where You Are - **Free tier** — no credit card, no time limit.

Deck and flatwork contractors are not an afterthought — the scope-of-work engine knows the difference between a ledger-attached deck, a freestanding pergola, a concrete flatwork pour, and an interlocking paver installation per ICPI guidelines.
