Dallas Development Code Chapter 51A establishes lot coverage maximums that vary by zoning district. Sec. 51A-4.217 limits accessory outside storage to 5% of lot area. Accessory structures in R-7.5(A) zoning cannot exceed 25% of the main structure's floor area. Maximum impervious surface coverage varies by district and affects stormwater management requirements. Lot coverage standards ensure adequate open space, drainage, and compatibility with surrounding development.
Dallas 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.
