Florida Milestone Inspections and Structural Integrity Reserve Studies (s. 553.899)

For aging condominium and cooperative towers across South Florida, two requirements now drive the repair calendar: the milestone structural inspection and the structural integrity reserve study. Both were tightened again in 2025, and both translate directly into permitted repair work. Endless Life Design performs the structural repairs and permitting that follow a milestone inspection.

WHY THE MILESTONE INSPECTION LAW EXISTS
Section 553.899, Florida Statutes, was enacted after the 2021 Champlain Towers South collapse in Surfside to impose a statewide structural inspection program for aging condominium and cooperative buildings. A milestone inspection is a structural safety inspection of the building's load-bearing elements and primary structural systems, performed only by a licensed engineer or architect.
WHICH BUILDINGS ARE COVERED
The requirement applies to buildings subject to the condominium form of ownership under Chapter 718 or the cooperative form under Chapter 719 that are three or more habitable stories in height. House Bill 913 (2025) clarified the trigger as three habitable stories — living, sleeping, eating, or cooking space — so a three-story building over a ground-level parking or storage level is the common case.
THE MILESTONE TIMELINE (30 YEARS, THEN EVERY 10)
The initial milestone inspection must be completed by December 31 of the year the building reaches 30 years of age, measured from the certificate of occupancy date, and every 10 years thereafter. A local enforcement agency may require the first inspection at 25 years where local conditions such as proximity to salt water warrant it, and transitional deadlines applied to buildings that had already passed 30 years when the law took effect.
PHASE 1 AND PHASE 2 INSPECTIONS
A Phase 1 inspection is a visual, qualitative assessment of the building's structural condition by a licensed engineer or architect. If the professional identifies signs of substantial structural deterioration, a more detailed Phase 2 inspection is required to evaluate the affected components and define the repairs.
STRUCTURAL INTEGRITY RESERVE STUDIES (SIRS)
The same buildings must complete a Structural Integrity Reserve Study identifying the major structural and operational components — such as roof, structure, fireproofing, load-bearing walls, plumbing, and waterproofing — and the reserves needed to maintain them. Reserves for the listed structural components are non-waivable, and HB 913 added a baseline funding plan requirement and set the SIRS completion deadline at December 31, 2025.
HOW THE LAW EVOLVED (SB 4-D TO HB 913)
The framework began with Senate Bill 4-D in 2022, was refined by Senate Bill 154 in 2023, adjusted by House Bill 1021 in 2024, and most recently updated by House Bill 913, effective July 1, 2025. HB 913 clarified the habitable-stories trigger, added reserve-funding flexibility tied to milestone repairs, and introduced conflict-of-interest disclosure rules for the professionals performing the work.
COUNTY AND MUNICIPALITY INSPECTION COMMENTS FOR PERMIT APPROVAL
Common comments include:
Milestone inspection past due for a building that has reached its 30-year mark.
Structural Integrity Reserve Study not completed or not funded to plan.
Phase 2 repair recommendations not addressed.
Milestone-driven structural repairs undertaken without the required permits.
Reserves waived for components the law makes non-waivable.
