What it does
§28 sorts Florida's municipal land-development codes on a single date. Regulation in place before August 1, 2024 is untouched and enforceable. Anything more restrictive or burdensome that a covered local government proposes or adopts before October 1, 2027 is "null and void ab initio" — void from inception, not merely suspended — and any resident or business owner may sue for declaratory and injunctive relief, take a preliminary injunction on a complaint showing a violation, and recover attorney fees and costs on success.
Two provisions cut the other way. §28(2) leaves enforceable any comprehensive-plan amendment, land-development-regulation amendment, site plan, development permit, or development order where the application was initiated by a private party other than the local government and that party owns the subject property. §28(3)(b) removes fees, costs, and damages where the governing body, on written notice, withdraws the measure within 14 days — or notices intent to repeal within 14 days and repeals within 14 days after.
§28(4) expires the section June 30, 2028. The prohibition it carries runs only to October 1, 2027.
The half that does not expire
§18 of the same chapter law created s. 252.422, Fla. Stat. — permanent, with no sunset — imposing the same three prohibitions for one year after every hurricane landfall on any federally declared county lying wholly or partly within 100 miles of the track, and on its municipalities. §28 is the temporary instrument; s. 252.422 is the durable one.
How the corpus reads it
The Grandfather Window named the structural effect correctly: cities sort into protected (Wellness Way Design Standards 2022, Minneola Ordinance 2024-10) and exposed (Agrarian Code October 2025; Groveland CDC V5 still drafting). The Window That Reloads corrects the direction, the porosity, and the duration — adopting inside the window is what creates exposure, landowner-initiated applications are not swept up, and the freeze re-arms with each storm rather than lifting once.
The minutes of Groveland's April 2, 2026 P&Z meeting summarize Anita Geraci-Carver's parting update as "All bills failed... Bill 180 expires June 2026", the origin of a misread that propagated through the corpus. Four 2026 bills to amend SB 180 failed: SB 840, SB 218, HB 217 and HB 1465, all dead on March 13, 2026. The June date matches SB 840, the fix that would have moved section 28's dates to June 30, 2026; it passed the Senate 38-0 and died in the House Intergovernmental Affairs Subcommittee. SB 840's failure left SB 180 in force two years longer, not shorter; the other three kept section 28's dates. The corrected timeline is published at SB 180: the real sunset (June 30, 2028) and the litigation that may end it sooner.
