What Is a Structural Integrity Reserve Study (SIRS)?
If you're on a Florida condo board, you've probably seen this acronym, in emails from your management company, on meeting agendas, in worried conversations between board members who aren't entirely sure what it means. Let's clear it up.
A Structural Integrity Reserve Study (SIRS) is a reserve study required by Florida law for condo and co-op buildings three or more habitable stories tall. It focuses on structural and life-safety components: the things that keep the building standing and keep people safe.
You might be thinking: isn't that just a reserve study? Not quite. A traditional reserve study covers everything your association maintains (pools, elevators, landscaping, all of it). A SIRS is narrower. It looks at eight specific structural categories. A licensed engineer or architect, or a certified reserve specialist or professional reserve analyst, inspects each one, estimates how many years of useful life remain, and calculates what repairs or replacement will cost.
What you get back is a document that tells your board what shape the building's structure is in and how much money you need set aside to maintain it.
Why SIRS exists
This requirement came out of the Champlain Towers South collapse in Surfside, Florida, in June 2021. A reserve study completed the year before found the building was only 6.9% funded, about $706,000 in reserves against a recommended $10.3 million. The structure needed work. The money wasn't there.
Florida's legislature responded with SB 4-D in 2022, creating the SIRS mandate. Buildings should know what condition their structure is in and have the money to fix what's found. That's the whole idea.
What a SIRS covers
Eight categories:
- Roof
- Structure. Load-bearing walls and primary structural systems
- Fireproofing and fire protection systems
- Plumbing
- Electrical systems
- Waterproofing and exterior painting
- Windows and exterior doors
- Any other item with deferred maintenance or replacement cost exceeding $25,000 that affects the components above
For each one, your engineer estimates remaining useful life and projected replacement cost. Florida law lets the association adjust replacement reserve assessments each year for inflation, so ask how the study treats cost growth for work that's a decade out.
One bit of flexibility: for components with an estimated remaining useful life of greater than 25 years, the SIRS may recommend that replacement reserves do not need to be maintained. The association must still reserve any deferred maintenance expense the SIRS recommends for those items.
Who needs one
Any residential condominium association with buildings three or more habitable stories in height. That word (habitable) is the key. HB 913, passed in 2025, clarified that parking garages and mechanical floors don't count toward the threshold. Three habitable stories is the line.
Every qualifying building on the property needs its own SIRS. Got a five-story tower and a two-story amenity building? Only the tower.
The requirement doesn't apply to buildings under three habitable stories, single-family homes through fourplexes, or components maintained by someone other than the association. If you're not sure whether your building qualifies, check your condominium documents and ask your engineer.
How it's different from a regular reserve study
Two different animals.
A traditional reserve study covers all common elements (elevators, HVAC, pools, landscaping, parking lots, clubhouse). Not mandated by state law. No licensing requirement for who does it. Owners can vote to waive the funding.
A SIRS covers only the eight structural and life-safety categories above. Mandated by Florida Statute §718.112(2)(g) for qualifying buildings. Must be performed or verified by a licensed engineer or architect, or a reserve specialist or professional reserve analyst certified by CAI or APRA. Reserves for SIRS items cannot be waived or redirected.
Most buildings need both. SIRS handles structural safety and legal compliance. The traditional study handles everything else.
What to do after you get yours
Your SIRS report tells you what each structural component will cost and when that cost arrives. The next step is a funding plan (right amount into reserves each year so the money is there when the work comes due).
This funding is mandatory. For a budget adopted on or after December 31, 2024, owners can no longer vote to waive reserves for SIRS items. The funding plan isn't optional.
Reserves Pro helps boards project SIRS findings over a 30-year timeline, showing how much goes into reserves each year to stay fully funded. When you can see the trajectory, setting the right contribution level is math instead of guesswork.
