Do I need a permit for addition or structural alteration in Tallahassee?

Permit required

Yes. In Florida, addition or structural alteration generally requires a permit, and Tallahassee is no exception.

A building permit is required for any addition and for structural alterations such as removing or altering load-bearing walls, changing the footprint, or altering the roof structure. The Florida Building Code only exempts ordinary minor repairs that do not cut into walls or remove load-bearing supports, so structural work is never exempt. Additions usually trigger zoning review and, in flood areas, elevation requirements.

Florida and local notes for Tallahassee

Structural work is specifically excluded from the HB 803 $7,500 exemption. Signed and sealed engineered plans are commonly required. Additions often trigger setback, lot-coverage, and floodplain review. Leon County's own permitting office is the Leon County Development Support & Environmental Management (DSEM), Building Plans Review and Inspection office, reachable on 850-606-1300 at https://cms.leoncountyfl.gov/Government/Departments/Development-Support-Environmental-Management. Its online permit portal is https://aca-prod.accela.com/LEONCO/Default.aspx. It issues permits for the unincorporated county. If your city does not run its own building department, and many smaller Florida municipalities do not, this is the office that will handle the job. An addition means a full plan review, so confirm submittal requirements and current review times before you commission drawings. Tallahassee requires a permit for any addition, and for any alteration or repair that costs more than $7,500 in labor and materials or is structural. Separate electrical, plumbing, mechanical, gas, and roofing permits are required for each trade. The residential checklist requires the site plan to show protected trees. On single family lots trees larger than 36 inches in diameter are protected, and removing one requires a mitigation plan. A property in FIRM Flood Zone A needs a 100-year flood elevation determination letter, and a soil test is required for any new structure larger than 400 square feet. A property with a historic overlay needs a Certificate of Appropriateness from the Tallahassee Trust for Historic Preservation before the city issues land use approvals.
