Hoover, AL Environmental Rules: Flood Elevation Requirements (2026)

Article III of Chapter 12, Flood Damage Prevention, readopted by Ord. No. 24-2636 on March 18, 2024, sets construction standards for every Special Flood Hazard Area in the city. Section 12-72(1) states the core freeboard rule: where base flood elevation (BFE) data is available, new construction, reconstruction, repairs to a repetitive loss structure, and substantial improvement of any structure or manufactured home shall have the lowest floor, including basement, and mechanical and electrical equipment servicing the structure elevated no lower than two feet above the BFE.

Structures built on solid perimeter foundation walls must also include flood-vent openings sized under § 12-72(3) so floodwaters can pass through unimpeded. Non-residential buildings may substitute dry floodproofing to the same two-foot design flood elevation under § 12-72(2), but only with a licensed engineer's or architect's certification kept on permanent file. The floodplain administrator, housed in the Building Inspections Department, reviews every permit application's plot plan for the proposed lowest-floor elevation, requires a post-construction elevation certificate before issuing a certificate of occupancy, and can grant a variance only through the Hoover Code Appeals Board under § 12-60.

Because Hoover straddles Jefferson and Shelby counties, the SFHA maps and BFE data an applicant must use depend on which county's FIRM panel covers the parcel. A violation is a criminal offense under § 12-46(c): a fine of up to $500, up to six months in jail, or both, with each day of noncompliance a separate offense, plus the city can withhold a certificate of occupancy, revoke the permit, or ask FEMA to issue a Section 1316 declaration that cuts off the property's flood insurance eligibility entirely.
