SIRS vs. Traditional Reserve Study: Key Differences
"We already have a reserve study. Doesn't that count?"
I hear this a lot. The answer is no. A SIRS and a traditional reserve study are different tools that cover different things. Having one doesn't satisfy the requirement for the other. Most qualifying buildings need both.
Here's how they differ and why it matters.
Side-by-side
| SIRS | Traditional Reserve Study | |
|---|---|---|
| What it covers | 8 structural/life-safety categories: roof, load-bearing structure, fire protection, plumbing, electrical, waterproofing, windows/doors, plus items over $25K affecting those systems | All common elements: elevators, HVAC, pools, landscaping, parking lots, clubhouse, everything else the association maintains |
| Legal requirement | Mandated by §718.112(2)(g) for 3+ habitable story buildings | Not mandated by state law |
| Who conducts it | Licensed engineer or architect | No licensing requirement |
| Reserve funding | Can't be waived or redirected; mandatory starting January 1, 2026 | Can be waived by owner vote |
| How often | Every 10 years | Typically every 3-5 years (no legal mandate) |
| State reporting | Must submit to DBPR within 45 days | No reporting requirement |
The core difference is scope. A SIRS looks at the building's bones -- structural and life-safety systems. A traditional study looks at everything the association pays to maintain, including pools, landscaping, and amenities that a SIRS doesn't touch.
Why you probably need both
A SIRS satisfies the legal requirement for structural components. But it won't tell you when your elevator needs modernization, when the HVAC is due for replacement, or when the pool deck needs resurfacing. Those items have lifecycles and replacement costs your budget needs to account for.
A traditional reserve study covers those items but doesn't meet the SIRS mandate. It may not have been done by a licensed engineer. It doesn't carry the same legal funding protections. And it doesn't get reported to the state.
The SIRS tells you whether the building is structurally sound and what it costs to keep it that way. The traditional study tells you what everything else will cost. Together, your board gets the complete picture.
One practical note -- some engineering firms offer combined packages that cover both SIRS-mandated components and traditional reserve items in a single engagement. If you're commissioning a SIRS anyway, ask about bundled pricing. It can save you time and money.
What happens if you only have one
SIRS only, no traditional study. You're legally compliant on structural components, but you're guessing on everything else. When the elevator bill or the parking lot repaving shows up and there's no plan, that's how special assessments happen.
Traditional study only, no SIRS. You have a financial plan for common elements, but you're not compliant with Florida law. The SIRS requirement is mandatory for qualifying buildings, and non-compliance is a breach of fiduciary duty. Your traditional study also may not meet the legal standard if it wasn't conducted by a licensed professional.
Neither is where you want to be.
Next steps
Not sure which studies your building has? Check what's on file. Look at the date, who conducted it, and what it covered. If you have a traditional study but no SIRS, close that gap first.
