Navigating Deck Permits in Washtenaw County, MI

Each city and township has different requirements. Here’s who handles what: Cities that manage their own permits: City of Ann Arbor (STREAM system) Townships under Washtenaw County Building Inspection: Augusta Township City of Dexter Lodi Township Saline Township Scio Township Sharon Township Webster Township We’ve pulled permits in all of these jurisdictions. We know the inspectors, the timelines, and what they’re looking for during inspections.
  • Most deck permits require:
  • Site plan showing setbacks and property lines
  • Structural drawings with joist spacing and beam sizes
  • Footing depth specifications (42 inches minimum)
  • Railing and stair details that meet code

We prepare all of this and submit it for approval. Permit timelines vary. Ann Arbor can take 2 to 4 weeks. County permits are usually faster, around 1 to 2 weeks, but it depends on the season and inspection backlog.

Understanding Washtenaw County's Climate and Soil

Washtenaw County averages 35 inches of precipitation annually with significant snowfall from December through March. Freeze-thaw cycles are harsh here. Ground freezes deep, then thaws, then freezes again.

All deck footings must go 42 inches deep minimum to get below the frost line. If footings are too shallow, your deck will shift every winter.

Soil types vary dramatically across the county:

  • Ann Arbor and Ypsilanti: Clay-heavy soils that hold water. Poor drainage can cause standing water under decks and destabilize footings.
  • Chelsea and western townships: More varied soil with better drainage in some areas, but still prone to frost heave.
  • Rural townships (Manchester, Bridgewater, Sharon): Mix of silt loam and clay. Some areas drain well, others don’t.
  • We test soil conditions at every site and design drainage systems that work for your specific property. Standing water rots wood framing and undermines concrete footings.

What We Build in Washtenaw County

Large custom decks

We handle complex, high-value projects. Multi-tier decks on steep slopes. Wraparound decks for historic homes. Estate-level builds with custom features like built-in seating, planters, and lighting systems.

If you have a difficult site—clay soil, poor drainage, steep grade, or proximity to water—we can engineer a solution.

Composite decking for Michigan weather

We’re TrexPro Platinum certified. That’s the highest certification level Trex offers. It means we’ve completed advanced training and met strict quality standards.

We install Trex, TimberTech, and Azek composite decking. These materials don’t rot, warp, or splinter like wood. They resist Michigan’s humidity, freeze-thaw cycles, and snow loads.

You don’t stain them. You don’t seal them. You rinse them off twice a year and they last 25 to 50 years.

Multi-level decks for sloped yards

Washtenaw County has varied terrain. Ann Arbor and Ypsilanti have hills. Chelsea and western townships have rolling landscapes. Rural areas near rivers have steep grades.

We design multi-tier decks that create functional outdoor living zones on uneven properties. Each level needs proper footings, drainage, and structural support. We engineer this so your deck doesn’t shift or settle over time.

Deck replacements and teardowns

Many older decks in Washtenaw County have undersized ledger bolts, shallow footings, or rotted framing. If your deck was built before 2000, it probably doesn’t meet current building codes.
We inspect existing structures, identify problems, and provide honest recommendations.

Sometimes you can repair sections. Often it makes more sense to tear down and rebuild correctly.

New footings, proper ledger attachment, code-compliant railings, and materials that will last 30 years.

DrySpace under-deck systems

DrySpace creates usable space under elevated decks. It’s a waterproof ceiling system that channels water away so you can use the area below for storage, seating, or outdoor living.

This works well for walkout basements, second-story decks, and anywhere you want to maximize space.
