Structural Integrity Reserve Study (SIRS)
Florida-required reserve study of structural components for condo buildings three stories or taller, prepared by qualified professionals.
What the work involves
Florida law requires condominium associations with buildings three stories or higher to complete a structural integrity reserve study at least every 10 years. The SIRS identifies required components (such as roof, structure, fireproofing, plumbing, electrical, waterproofing, windows and doors), their remaining useful life and replacement cost, and a funding plan. It is typically prepared by or with a licensed engineer or architect, and associations generally can no longer waive reserves for these components.
Local conditions we plan for
- Deep frost penetration
- Heavy snow loads
- Great Lakes shoreline erosion
- Karst in the southwest Driftless Area and Door County
Building code: IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (ICC adoption chart, April 2026).
When you need it
- Association has a building three or more stories
- SIRS due or prior study expired
- Milestone inspection identified major repairs
- Budgeting for mandatory reserves
Frequently asked questions
How much does structural Integrity Reserve Study (SIRS) cost?
Across the US, structural Integrity Reserve Study (SIRS) usually costs $3,000 to $30,000 per association. Estimate. Depends on building size and number of components.
How long does structural Integrity Reserve Study (SIRS) take?
Plan on 3 to 10 weeks from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.
Is a permit required for structural Integrity Reserve Study (SIRS)?
Often not on its own, but the findings frequently lead to work that does need a permit. We tell you which parts of the follow-up work your local building department will review, and can prepare those drawings too.
How do I verify an engineer's license in Wisconsin?
Engineers practicing in Wisconsin are licensed by the Wisconsin Examining Board of Architects, Landscape Architects, Professional Engineers, Designers and Professional Land Surveyors. You can confirm a license number and its status in the board's public license search before you sign a contract.
How deep is the frost line in Wisconsin?
Wisconsin Uniform Dwelling Code SPS 321.16 requires footings to be below frost penetration or at least 48 inches below adjacent grade, whichever is deeper (one and two family dwellings). Local building departments set the required footing depth, so confirm the exact figure for your county before designing foundations or retaining walls.
Which building code applies in Wisconsin?
IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
