Do I need a permit for addition or structural alteration in Longboat Key?
Yes. In Florida, addition or structural alteration generally requires a permit, and Longboat Key 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.

Local and county notes for Longboat Key
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. Sarasota County's own permitting office is the Sarasota County Planning and Development Services office, reachable on 941-861-5000 at https://www.scgov.net/government/planning-and-development-services/building. Its online permit portal is https://building.scgov.net/. 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. Longboat Key permits are handled by the Longboat Key Planning, Zoning & Building Department - Building Division, reachable on 941-316-1966 at https://www.longboatkey.org/202/Building-Division. Sarasota County also issues permits for the unincorporated county, and many smaller Florida municipalities contract building services to it rather than running a department of their own, so confirm which office covers your address before you apply.
