Do I need a permit for window or exterior door replacement in Altha?
Yes. In Florida, window or exterior door replacement generally requires a permit, and Altha is no exception.
Replacing windows or exterior doors, including garage doors, generally requires a permit in Florida even when the new unit is the same size, because the opening must meet current wind-load requirements. Each product must carry a valid Florida Product Approval, or a Miami-Dade Notice of Acceptance in High-Velocity Hurricane Zones. A few jurisdictions allow narrow same-size, glass-only exceptions.
Local detail for Altha: The Town of Altha official site is minimal and publishes no building department or permit process. The Calhoun County Building Department page confirms the county's contacts (20867 SE Fannin Ave, Blountstown; 850-674-8046) but does not specifically name Altha or state it issues permits within the town. Altha is plausibly served by the Calhoun County Building Department, but this town-specific routing could not be confirmed on an official source. Town Hall: 850-762-3280.
Local and county notes for Altha
Like-for-like replacement usually does not waive the permit in Florida. The product approval must match the wind-load rating for your specific address. Calhoun County's own permitting office is the Calhoun County Building Department, reachable on 850-674-8046 at https://www.calhouncountyfl.gov/building-department/. 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. Replacement units need Florida Product Approval documentation, and whichever office serves your address will want the approval numbers with the application.
