What is the minimum lot size in Troy, Michigan?

Minimum lot size in Troy ranges from 7,500 sq ft to 21,780 sq ft depending on the R-1 district (Section 4.06.C). For lots with public sewer:

• R-1A: 21,780 sq ft, 120 ft minimum width.
• R-1B: 15,000 sq ft, 100 ft width.
• R-1C: 10,500 sq ft, 85 ft width.
• R-1D: 8,500 sq ft, 75 ft width.
• R-1E: 7,500 sq ft, 60 ft width.

Lots without public sewer face larger minimums, from 21,780 to 30,000 sq ft with widths of 110 to 150 ft (Section 4.06.C).

An existing lot smaller than the minimum raises nonconformity questions, and a lot split that would create an undersized parcel is a separate review. Check your district on the city zoning map, or talk to the Planning Department at 248-524-3364 before buying or splitting land.
