Dunedin establishes maximum lot coverage and impervious surface ratios in Chapter 103 zoning. Limits vary by district and govern building footprint plus driveways, patios, and pools, with stormwater rules adding additional constraints in flood and conservation areas.
Lot coverage and impervious surface limits in Dunedin are part of the zoning regulations in Chapter 103, including section 103-23.16.3.2 on lot requirements. Each zoning district sets a maximum percentage of the lot that may be covered by buildings and a separate maximum for impervious surfaces such as driveways, patios, sidewalks, and pool decks. Stormwater management rules require pervious area for runoff control. Additional restrictions apply in coastal and flood hazard zones along St. Joseph Sound. Exceeding lot coverage requires either redesign or a variance. Replacement of existing impervious surfaces in nonconforming lots may be allowed without expansion if no net increase results.
Exceeding lot coverage triggers permit denial, stop-work orders, required removal of excess impervious area, and possible stormwater fines for runoff violations.
