Neither Washtenaw County nor Ann Arbor caps the number of nights per year an STR may operate. Instead, an STR is defined by stay length: a dwelling unit in which guests may stay for up to 30 consecutive days. Longer stays fall under regular rental rules.
Ann Arbor's Chapter 97 does not impose an annual night cap or a limit on how many separate rentals a host may take in a year. The controlling limit is per-stay: an STR is a dwelling unit in which guests may stay for up to 30 consecutive days, and Michigan's accommodation tax likewise defines a transient guest as staying less than 30 consecutive days. Once a booking reaches 30-plus days, it is treated as a registered rental under the Housing Code (Chapter 105), which requires inspection and a Certificate of Compliance. Townships and other Washtenaw cities set their own limits, if any — several impose no night cap at all.
Renting beyond 30 consecutive days without meeting Housing Code registration and Certificate-of-Compliance requirements is a code violation.
