Document the condition
Note where the movement or crack shows up, when you first noticed it, whether it tracks with weather, and any earlier repairs at the property. A handful of photos and rough measurements make the first conversation far more useful.
Read the local context
The city's Old West Side, platted starting in 1845 and listed on the National Register in 1972, still carries two-story frame houses built for a fast-growing 19th-century college town -- about 85% clapboard-clad, the rest brick or stucco -- later filled in with Dutch Colonials, bungalows, and Tudor cottages on small lots. Underneath that older core and the newer subdivisions built across Washtenaw County sits a mix of sand, gravel, and clay-rich glacial till left by retreating ice roughly 14,000 years ago -- fertile ground that also drains poorly, one reason foundation inspection, crack repair, and settlement work stays in steady demand across the area.
Ask what will be hidden
Cracks and sticking doors are clues, not diagnoses: around Ann Arbor, glacial till clay loam along the Huron River means grading, drainage, framing, and foundation type all need to be weighed together before a repair plan is proposed. Whatever gets covered back up on an Ann Arbor job — drainage tie-ins, prep work, fasteners — belongs in the written scope, described before it disappears.

What official local sources add
The City of Ann Arbor adopted a Floodplain Management Overlay Zoning District in 2021 that sets standards above the federal minimum, requiring new residential construction to have its lowest floor elevated at least 1 foot above the mapped 0.2%-annual-chance flood elevation. The city has also taken part in FEMA's Community Rating System since 2017, reaching Class 6 in 2018 -- worth checking with the city's floodplain and stormwater programs before foundation, grading, or exterior work begins.
