Philadelphia's zoning code sets maximum lot coverage (open area requirements) by district in Chapter 14-700 dimensional standards. Each zoning district specifies the maximum percentage of the lot that may be covered by structures. Open area requirements ensure adequate light, air, and stormwater management. Lot coverage variances require Zoning Board approval.
Philadelphia 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.
