Maximum lot coverage in Jacksonville is established by zoning district under Jax Ord. Code Ch. 656, Part 3 (Schedule of District Regulations). Each residential district (RLD-60, RLD-50, RLD-40, RLD-TND, RLD-TNH, RMD-A through RMD-D) specifies maximum lot coverage percentages. This includes all roofed structures — the principal building, garages, sheds, carports, and other accessory structures. Impervious surface also affects stormwater fees under Ch. 754.
Jacksonville's lot coverage regulations limit the total area of a lot that may be covered by buildings, driveways, patios, and other impervious surfaces. In single-family residential zones, maximum lot coverage is typically 35–50% of total lot area. Multi-family and commercial zones allow higher coverage (60–80%). Lot coverage includes all roofed structures, concrete/asphalt surfaces, and any material that prevents stormwater infiltration. Permeable pavers, green roofs, and rain gardens may qualify for impervious surface credits, effectively allowing additional coverage. Accessory structures (sheds, detached garages, pools) count toward total coverage. Exceeding lot coverage limits requires a variance from the zoning board. Florida's stormwater management requirements and water management districts regulate usage concerns support lot coverage restrictions.
Exceeding lot coverage without variance: $200–$1,000 fine and removal/modification order. Building permit denial for projects exceeding limits. Variance application fees: $200–$500.
