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.
Milwaukee zoning code limits maximum lot coverage, defined as the percentage of a lot covered by buildings, driveways, patios, and other impervious surfaces. Typical residential limits are 40 to 60% depending on zoning district and lot size. Lot coverage calculations include primary structures, accessory buildings, paved areas, and covered patios. Permeable pavers may receive partial credit in some jurisdictions. Exceeding lot coverage requires a variance. Stormwater management requirements may apply to highly impervious lots.
Exceeding lot coverage: correction required. May need to remove impervious surface. Fines $200 to $1,000.
