Delray Beach lot coverage limits per LDR 4.3.4: R-1-AA max 40 percent building coverage, R-1-A 40 percent, RM multifamily 40 percent. Impervious surface ratio (ISR) limits total hardscape to 50-70 percent depending on zone for stormwater management.
Building coverage includes main structure and attached garage. Pools, patios, and driveways count toward ISR, not building coverage. Beach-area lots in AE/VE flood zones have stricter ISR (50 percent) to manage runoff into ocean. Pervious pavers can earn partial ISR credit. Contact Delray Beach at (561) 243-7000 for enforcement.
Exceeding coverage: variance required or demolition. Unpermitted additions: $250-$500 plus doubled permit fees.
