Taylor, MI Building Setbacks & Zoning: Lot Coverage Limits (2026)

Appendix A, table 3.03, Area, Height and Placement Requirements, sets two separate lot coverage ceilings for every single-family district. The 'All Buildings' column caps the footprint of every structure on the lot; the 'All Impermeable Surface' column also counts driveways, patios, decks and pools. In the R-1A district those limits are 25 percent for buildings and 65 percent including other impermeable surfaces. R-1B allows 30 percent building coverage with the same 65 percent impermeable ceiling, and R-1C allows 30 percent building coverage but a higher 75 percent impermeable ceiling, reflecting its smaller 7,200-square-foot minimum lot size.

Subsection (l) of section 3.03 explains why there are two numbers: lot coverage 'shall be regulated by two measures,' the percentage covered by buildings alone and the percentage covered by buildings plus other impermeable surfaces such as pavement, decks and pools. A homeowner adding a shed, a paver patio or an in-ground pool has to run the math against both ceilings, not just the building footprint, because driveways and decks eat into the impermeable allowance long before the house itself approaches the building-coverage cap. Building and Safety checks both percentages against the recorded lot area at plan review, before any permit for an addition, accessory building, or new paved surface is issued.
