Sumter County, FL Building Setbacks & Zoning: Setback Rules (2026)

Section 13-412(a) makes Tables 13-413A and 13-416A the source of minimum side and rear setback distances, applying them to every substantial above-ground structure, including accessory structures, plus in-ground and below-ground structures, unless the Land Development Code specifies otherwise for a particular use. 5C, RR1 and RR1C, dropping to 10 feet in the urban residential districts R2M, R2C, R4M, R4C, R6M and R6C, and back up to 15 feet in the high-density multifamily districts HDR-12 and HDR-24. Front setbacks are handled separately under Section 13-412(c), which measures from the road right-of-way or centerline using Table 13-412A's road-classification schedule rather than the residential dimensional table.

Section 13-412(b) sets a flat 10-foot setback from the normal high-water elevation of on-site or off-site ditches and canals, with an exception allowing a boathouse on a shoreline if it still meets the minimum side setback for accessory structures. Measurement runs to the nearest vertical wall or support of the building, and an above-ground projection of more than two feet into the required setback triggers a compensating setback increase elsewhere on the structure. A corner lot platted before the chapter's effective date with less than 75 feet of road frontage can have its setback reduced by one foot for every foot of frontage short of 75, but never below 15 feet.
