Florida Ground Snow Load: What the Adopted Code Carries

Florida adopts the national building code without a ground snow load amendment of its own, so the governing figure for a given address is the one the code's own table carries, and the body that applies it is Florida Building Commission, Department of Business and Professional Regulation, Office of Codes and Standards. 17 states are in the same position, which makes it the second commonest arrangement in the country. Florida publishes ground snow loads through Florida Building Commission, Department of Business and Professional Regulation, Office of Codes and Standards, and the jurisdictions reached for this had put none into a public document at the time they were read.

Florida Building Commission, Department of Business and Professional Regulation, Office of Codes and Standards: one statewide code, enforced by local building departments, with no separate state snow load map. In its own words: “(1) The Florida Building Code, 8th Edition (2023), as updated by the Florida Building Commission on June 20, 2023, April 16, 2024, August 13, 2024, December 10, 2024, December 20, 2024, April 15, 2025, and December 9, 2025, and incorporated herein by reference is hereby adopted as the building code for the State of Florida.”

Florida carries one figure across the state, which is the rarest arrangement in the country.

Florida Building Commission, Department of Business and Professional Regulation adopts Florida Building Code (8th Edition (2023)). Florida amended it rather than adopting it whole, and 22 states have done the same. The adopting rule reads: “(1) The Florida Building Code, 8th Edition (2023), as updated by the Florida Building Commission on June 20, 2023, April 16, 2024, August 13, 2024, December 10, 2024, December 20, 2024, April 15, 2025, and December 9, 2025, and incorporated herein by reference is hereby adopted as the building code for the State of Florida.”

A ground snow load is a weight per unit area and not a depth, and the two are joined only by the density of the snow on the day, which is why the published documents give the load and leave the depth out. Wet spring snow and dry January snow of the same depth are different weights on the same roof. Florida Building Commission, Department of Business and Professional Regulation, Office of Codes and Standards works in loads for that reason, and so does every figure set out below.

The code's figure is applied to a given address by Florida Building Commission, Department of Business and Professional Regulation, Office of Codes and Standards. The document behind it is Rule 61G20-1.001 Florida Building Code Adopted, published by Florida Building Commission, read on September 23, 2026. It establishes the point this way: “(2) The material incorporated and adopted in subsection (1), is copyrighted material that is available for public inspection and examination at the Department of State, Administrative Code and Register Unit, The Capitol, 400 South Monroe Street, Room 701, Tallahassee, Florida 32399, and at the Department of Business and Professional Regulation, Office of Codes & Standards, 2601 Blair Stone Road, Tallahassee, Florida 32399-0772.”

14 of 50: Connecticut, Indiana, Maryland, Massachusetts, Michigan, Minnesota, Montana, New Hampshire, New Jersey, North Carolina, Rhode Island, Utah, Vermont, Wisconsin. The other 36 split into 17 that adopt the national code without a snow amendment and 19 that leave every figure to a county or city building department. That is the single most useful fact about this subject and no one state's own website carries it.
