What is a Structural Integrity Reserve Study (SIRS) and Do You Need One?

If you sit on a Florida condominium or cooperative board, you've probably heard the term SIRS used almost interchangeably with 'reserve study.' They are not the same thing — and the difference matters.

What is a SIRS?

A Structural Integrity Reserve Study is a state-mandated reserve study focused specifically on the structural and life-safety components of a building. It must be performed by a qualified professional (typically a licensed engineer or architect) and updated at least every 10 years. The SIRS produces an inventory of components, an estimate of remaining useful life, a replacement cost projection, and a funding plan that the association is legally required to follow.

Who needs a SIRS?

Florida condominium and cooperative associations of buildings three stories or higher are required to have a SIRS. The requirement applies regardless of building age, occupancy type, or geographic location within Florida. Single-family HOAs are not currently subject to the SIRS mandate.

What components must be included?

• Roof
• Structure, including load-bearing walls and other primary structural members
• Fireproofing and fire protection systems
• Plumbing
• Electrical systems
• Waterproofing and exterior painting
• Windows and exterior doors
• Any other item with a deferred maintenance or replacement cost exceeding $10,000 that, if not properly maintained, would negatively affect the items above

How does the SIRS interact with the Milestone Inspection?

The Milestone Inspection diagnoses current structural condition; the SIRS plans the funding required to keep that condition acceptable over time. The two studies are intentionally complementary, and most engineering firms — including ours — recommend scheduling them together to avoid duplicated site visits and inconsistent findings.

What happens if our association doesn't fund the SIRS as recommended?

Florida law requires that the association fund reserves consistent with the SIRS. Owners can no longer vote to waive or reduce funding for SIRS-covered components. Boards that ignore the funding plan expose the association — and individual directors — to legal and fiduciary risk.

How much does a SIRS cost?

Cost varies with building size, complexity, and the availability of original drawings, but most mid-rise condominiums fall within a predictable range. Bundling the SIRS with a Milestone Inspection typically reduces overall cost by 15–25%.
