Milwaukee's zoning code (Chapter 295) limits the percentage of a lot that can be covered by buildings and impervious surfaces. In single-family residential districts, maximum building coverage is typically 35-40% of the lot area. Lot coverage includes the principal structure, accessory buildings, and other permanent structures. Impervious surface coverage (including driveways and patios) may have separate limits. Exceeding lot coverage limits requires a variance from the Board of Zoning Appeals.
