Columbia County, FL Building Setbacks & Zoning: Structure Height Limits (2026)

Sec. 4.7.8 of the county's Land Development Regulations caps the maximum height of structures in RSF-1, RSF-2 and RSF-3 at 35 feet, stating flatly that 'no portion shall exceed' that limit, and directs builders to Sec. 4.2 for the specific list of features excluded from the height calculation, such as chimneys, antennas or similar appurtenances typically carved out of height limits. The same 35-foot ceiling repeats across the county's other primary residential and rural categories, including the RR Rural Residential district under Sec. 4.6.8 and the Agricultural districts under Sec.

4.5.10 and 4.4.8, so a homeowner moving between zoning categories inside unincorporated Columbia County will not find a taller residential allowance by changing district. Commercial districts are treated differently: the CG Commercial, General district allows structures up to 50 feet under Sec. 4.13.8, with the planning and zoning board or board of adjustment able to approve taller buildings where compatible with surrounding development, subject to FAA and airport zoning height limits near local airports. A property owner who wants to exceed the 35-foot residential cap, for a tower, silo or similar structure not covered by the Sec. 4.2 exclusions, needs a variance from the board of adjustment rather than an administrative exception.
