St. Petersburg limits building lot coverage and impervious surface ratios by zoning district under Chapter 16, with single-family lots typically capped at 40-50 percent building coverage.
Chapter 16 of the St. Petersburg City Code establishes maximum lot coverage and impervious surface area ratios for each zoning district. In single-family residential districts, principal-building lot coverage is generally limited to about 40 to 50 percent of the lot area, with combined impervious surface (including driveways, walkways, and patios) commonly capped at 65 to 70 percent. The 2025 Residential LDR Update introduced floor-area-ratio (FAR) limits to address scale and compatibility in Neighborhood Traditional districts. Excess impervious coverage triggers stormwater management requirements under Section 16.40.030 and may require on-site retention. Pervious paving and approved surface treatments can reduce calculated impervious area.
Exceeding lot coverage triggers permit denial or stop-work orders. Owners may be required to remove pavement or buildings to come into compliance, and stormwater violations carry separate fines.
