House Bill 401 (2021) created a process whereby a person may petition the Florida Building Commission for a nonbinding advisory opinion about whether a local regulation constitutes a technical amendment to the Florida Building Code. The Commission is required to adopt a form for the petition and directions for filing, and this proposed rulemaking will do so. HB 401 also modified the structure of subsection 553.73(4), F.S., in a manner that now subjects all local code amendments to triennial review by the Commission, and potential expiration. Prior to HB 401, only local technical amendments were subject to triennial review and potential expiration, and the Commission’s rule will be updated to track the new statutory language. The Commission also intends to correct an outdated citation in the current rule.
