Full Breakdown
1 sets the R-1 Development Parameters Table that governs unincorporated single-family lots; incorporated cities such as St. Petersburg, Clearwater and Largo apply their own zoning tables. The R-1 table caps building height at 35 feet and requires a minimum lot area of 9,500 square feet, 80 feet of width and 90 feet of depth. Minimum setbacks are 20 feet for the front building line, a reduced 10 feet for a front porch, patio or deck, 6 feet for an interior side yard, 10 feet for a side yard on a corner lot's street side, and 10 feet for the rear yard.
Zero-lot-line single-family detached homes in new subdivisions may use a 0-foot setback on one side yard, provided the opposite side yard is at least 10 feet, per table note 4. 75. The table's own footnotes send readers to the county's general setback-measurement rules in § 138-3505: setbacks run the shortest distance from the property line perpendicular to the structure, corner and multi-frontage lots are treated as having one front setback (generally the address-bearing, narrower frontage), and portions of a lot abutting an alley or a public park or trail need at least a 10-foot setback.
Nearby zoning districts use the same setback figures on smaller or larger lots; the R-2 district, for example, applies the identical 20/10/6/10/10 setback pattern but allows a smaller 7,500-square-foot, 70-by-80-foot lot.
Violations & Fines
Building a structure that encroaches into a required front, side, or rear setback without an approved variance, waiver, or administrative adjustment is a zoning violation subject to code enforcement action and the county's general penalty under § 1-8, up to a $500 fine, with continuing noncompliance treated as a separate daily offense.
