Summary
Jacksonville caps single-family structures in every Residential Low Density (RLD) zoning district, from RLD-120 down to RLD-40 and RLD-TND, at 35 feet under Ordinance Code Sec. 656.305(g). The same section sets the yard setbacks tied to that height, so buying a bigger lot inside these districts does not buy extra height.
(f)Minimum yard requirements. The minimum yard requirements for all uses and structures are as follows; provided, however that unenclosed front porches may extend five feet into the required front yard setback, and side opening garages may extend five feet into the required front yard setback as long as the garage doors do not face the street in the RLD-120, RLD-100A, RLD-100B, RLD-90, RLD-80, RLD-70, RLD-60, RLD-50, and RLD-40 Zoning Districts.(1)RLD-120:(i)Front—25 feet.(ii)Side—7.5 feet.(iii)Rear—10 feet....(9)RLD-40:(i)Front—20 feet.(ii)Side—3 feet.(iii)Rear—10 feet.(g)Maximum height of structures. 35 feet.(h)Minimum open space.

Full Breakdown
Chapter 656's Sec. 305 governs the Low Density Residential Category, which spans nine base districts, RLD-120 through RLD-40, plus RLD-TND and RLD-TNH. Each district carries its own minimum lot width and area, from RLD-120's 120-foot width and 43,560-square-foot lot down to RLD-40's 40-foot width and 4,000-square-foot lot, and its own yard setbacks under Sec. 5-foot side and 10-foot rear yard, tapering to a 20-foot front, 3-foot side and 10-foot rear yard in RLD-40. Sec. 305(g) then applies one flat number across all of them: 'Maximum height of structures.
35 feet,' with no exception written into the section. That differs from the Medium Density Residential Category next door in Sec. 306, where non-single-family buildings can exceed 45 feet if every required yard grows by a matching foot. The Residential Rural-Acre (RR-Acre) district's height limit is set separately in Sec. 304, not here. Sec. 305(f) does allow unenclosed front porches to extend five feet into the front setback and side-opening garages to do the same, and Sec. 305(h) caps overall gross density at the Land Use Category level with excess density platted as open space.
A homeowner who needs to exceed 35 feet, for a cupola, elevator override or elevated flood-zone foundation, must apply for an administrative deviation from the Zoning Administrator under Sec. 109(e)-(j): a complete written application triggers a hearing within 30 days, and the Zoning Administrator must find the extra height is needed because of the lot's physical shape, topography or similar site condition, not cost savings.
Violations & Fines
Building over the 35-foot cap without an approved deviation is a civil infraction under Sec. 656.111(a). Fines run $50 to $500 per violation, and each day the oversized structure stands counts as a separate offense under Sec. 656.111(b). A contractor or agent who builds without authorization faces escalating civil penalties of $1,000, $2,000 and $3,000 for a first, second and third violation under Sec. 656.111(h), plus a three-month freeze on new zoning approvals until the penalty is paid. The Municipal Code Compliance Division and the Municipal Code Enforcement Board handle enforcement under Sec. 656.110.
