Do I need a permit for addition or structural alteration in Unincorporated Manatee County?

Permit required

Yes. In Florida, addition or structural alteration generally requires a permit, and Unincorporated Manatee County 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 Unincorporated Manatee County

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. Manatee County's own permitting office is the Manatee County Building Division (Development Services Department), reachable on (941) 748-4501 at https://www.mymanatee.org/departments/development-services-department/building-division. Its online permit portal is https://aca-prod.accela.com/MANATEE/Login.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. Manatee County lists additions (including to mobile homes) and renovation of existing structures as work requiring a permit and a licensed contractor or qualifying owner-builder. The county's One and Two Family Submittal Checklist requires a geotechnical soil report for additions and existing and proposed floor plans for renovations. In a flood hazard area, elevations must show the base flood elevation and floor protection elevation, and the Floodplain Management Section (Flood@mymanatee.org) reviews the application; county forms include the Determination of Improvement and the Non-Conversion Agreement. The county requires an alteration permit before any spray foam insulation is applied, with manufacturer specifications.
