Florida's SIRS Rules: SB 4-D, SB 154, and What Post-Surfside Compliance Looks Like

The 2021 partial collapse of Champlain Towers South in Surfside, Florida killed 98 people and rewrote Florida's structural-integrity rules for residential condominium associations within twelve months. The legislative response — SB 4-D (2022), SB 154 (2023), and HB 1021 (2024) — created the most extensive structural-reserve regime in the United States. Communities outside Florida should read it anyway: it is the working template for what's coming nationally.

Two parallel regimes

Florida law now requires two distinct, mandatory inspections of condominium and cooperative buildings three stories or higher:

Milestone inspection — Fla. Stat. § 553.899. A structural inspection by a licensed Florida architect or engineer at 30 years from the certificate of occupancy (25 years for buildings within three miles of a coastline). A Phase II destructive-testing inspection follows if Phase I identifies "substantial structural deterioration." Recurrence: every 10 years thereafter.
Structural Integrity Reserve Study (SIRS) — Fla. Stat. § 718.112(2)(g). A reserve study scoped specifically to the structural-integrity components of the building. Required initially by December 31, 2024 (twice extended; see HB 1021 for current dates) for buildings three stories or higher, with mandatory updates every 10 years.

What a SIRS must cover

By statute, a SIRS estimates remaining useful life and replacement cost for the following components, at minimum:

Roof.
Load-bearing walls and other primary structural members.
Floor.
Foundation.
Fireproofing and fire-protection systems.
Plumbing.
Electrical systems.
Waterproofing and exterior painting.
Windows and exterior doors.
Any other item with a deferred-maintenance expense or replacement cost greater than $10,000 that, if not maintained, would adversely affect any of the listed items.

The SIRS must be prepared by a credentialed reserve specialist or licensed engineer/architect; it is not a self-prepared document.

The reserve-waiver prohibition

The single most consequential change: for SIRS components, owners may no longer waive or reduce reserve contributions. § 718.112(2)(g)(4). Prior law allowed owners to vote to underfund or skip reserve contributions year over year; an entire generation of Florida condominiums did. That is over. Boards that historically operated with sub-30% reserves are now legally required to fund SIRS components fully.

The financial impact is real and uneven. Associations that had been chronically underfunded face large catch-up assessments. The market has begun to price this: pre-1990 oceanfront condominiums in Florida have seen measurable price compression directly attributable to SIRS catch-up exposure.

Compliance milestones

Milestone inspections — phased by year of certificate of occupancy; current statutory deadlines are in § 553.899(3) and have been extended; check the most recent legislative session.
Initial SIRS — completed and presented at a board meeting; reflected in the next budget cycle's reserve contribution.
Annual budget — SIRS-derived reserve contributions are now a baseline, not a board choice.
Sale disclosure — condominium re-sale disclosures must include the milestone-inspection status and a copy of the SIRS summary.

What it signals nationally

The Florida regime is not alone. Hawaii enacted Act 189 (2022) requiring structural-engineering reserves; California's SB 326 (2019) imposed balcony/elevated-element inspection requirements after the 2015 Berkeley balcony collapse; New Jersey's "Radburn Act" amendments and proposed structural-reserve bills are tracking similar themes. Boards anywhere that maintain mid-rise residential structures should expect some version of the Florida model within five to ten years.
