TL;DR
A structural integrity reserve study (SIRS) is a Florida-mandated inspection of a condo building's structural components (roof, load-bearing walls, foundation, waterproofing, plumbing, electrical) used to set full, non-waivable reserve funding. Orlando buildings 3+ stories, 25/30+ years old, had to have one done by December 31, 2024 under section 718.112(2)(g), Florida Statutes. Costs typically run $5,000 to $20,000+ depending on square footage and building complexity.
What is a structural integrity reserve study (SIRS)?
A structural integrity reserve study is a formal, on-site inspection and financial analysis required for most Florida condominium buildings that are three stories or more. It's not the same as a milestone inspection, though the two get confused constantly. A milestone inspection checks whether the building is structurally sound right now. A SIRS looks at specific structural components, estimates their remaining useful life, and calculates how much money the association needs to set aside in reserves to repair or replace them without a surprise special assessment. Florida law spells out exactly what a SIRS has to cover. Under section 718.112(2)(g), Florida Statutes, the study must address at minimum: roof, load-bearing walls or other primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, and windows [1]. The statute defines these as "structural components" for reserve purposes, separate from cosmetic items like landscaping or a clubhouse paint job. Who can actually do this study matters. The statute requires it be performed by a licensed engineer or licensed architect [1]. A property manager or a reserve-fund software vendor can help organize the paperwork. But the inspection itself, and the professional judgment behind the remaining-life and replacement-cost figures, has to come from someone holding an active Florida license through DBPR. No exceptions.
Is a SIRS the same thing as a regular reserve study?
No, and this distinction trips up a lot of Orlando boards that had a "reserve study" done years ago and think they're covered. A traditional reserve study, the kind many associations have voluntarily commissioned for decades, can cover everything from paving to pool equipment to painting, and boards have historically been allowed to vote to waive or reduce that funding. A SIRS is narrower in scope (structural components only) but much stricter in consequence. Once your association has a SIRS on file, the reserves for those specific structural items can no longer be waived or underfunded by membership vote, per section 718.112(2)(f)4, Florida Statutes [1]. That's the real teeth of the 2022 and 2023 legislative changes passed after the Champlain Towers South collapse in Surfside. So you likely need both. A SIRS for the structural line items is mandatory, full-funded, no waiving. A broader reserve study for non-structural common elements is still optional to fully fund, subject to membership vote under current law, if your board wants one. See our guide on reserve study requirements for how the two overlap.
What is a reserve study for an HOA, and does it work the same way?
This is where Orlando's mixed housing stock creates real confusion. A reserve study for an HOA (a single-family home community, a townhome association, or any homeowners' association governed by chapter 720 rather than chapter 718) is a financial planning tool. It's an inventory of common-element assets (roads, retention ponds, clubhouse roofs, fencing), their expected remaining life, and the savings needed to replace them on schedule. Here's the key difference: the mandatory SIRS requirement under section 718.112(2)(g) applies to condominiums under chapter 718, not to homeowners' associations under chapter 720. If your Orlando community is single-family homes or townhomes governed by an HOA rather than a condo association, you are not subject to the SIRS mandate. You may still have a milestone inspection obligation if you have a building three stories or taller. That's rare for pure HOAs, but it happens with amenity buildings or mixed-use structures. Plenty of well-run HOAs commission voluntary reserve studies anyway. Underfunded reserves are the single biggest cause of special assessments in Florida regardless of statute. See our HOA reserve study guide for how HOA boards should think about funding levels even without a legal mandate.
What is an HOA assessment, and how is a special assessment different?
A regular HOA assessment (sometimes just called "dues" or "maintenance fees") is the recurring fee every owner pays, usually monthly or quarterly, to cover operating expenses and reserve contributions. It's set by the board's annual budget and is predictable, the same way a mortgage payment is predictable. A special assessment is different. It's a one-time additional charge, levied outside the normal budget cycle, usually because reserves fell short of an unexpected or under-planned expense: a roof replacement that came in over budget, storm damage not fully covered by insurance, or a structural repair flagged by a milestone inspection or SIRS. SIRS-driven special assessments have become common across Central Florida since the 2024 deadline. Many associations discovered their structural reserves were badly underfunded once an engineer actually priced out roof, foundation, and waterproofing replacement. Boards facing this should read our HOA special assessment piece before calling a vote, since notice and voting requirements differ depending on your governing documents and whether the assessment exceeds certain thresholds set in your declaration.
How much should an HOA or condo have in reserves?
There's no single dollar figure regulators publish and no state-mandated percentage funding target in Florida law. Be skeptical of anyone who quotes you a universal rule like "70% funded" as if it's a legal standard. It isn't. What the law does require, for condos under the SIRS mandate, is full funding of the specific structural components identified in section 718.112(2)(g), calculated component by component based on each item's estimated remaining useful life and replacement cost [1]. In practice, reserve planners use a couple of industry benchmarks even though they're not Florida statutory requirements: percent-funded (current reserve balance divided by the ideal balance for where components are in their life cycle) and full-funding versus threshold-funding models. Community association industry groups often cite 70% funded as a healthy target and under 30% funded as a red flag, but these are professional-practice conventions, not Chapter 718 requirements. What you actually need to know as a board member: get the SIRS done by a licensed engineer or architect, get the component-by-component numbers, and fund those structural line items at the full amount the study calculates. That funding is no longer optional to skip by membership vote for condos under current Florida law [1]. Beyond the mandatory structural components, how much more to save is a board judgment call based on your building's age, coastal exposure, and appetite for future special assessments.
How much does a reserve study or SIRS cost in the Orlando area?
Costs vary widely based on building size, number of structural components, and whether you're hiring a firm doing dozens of these a year versus a smaller engineering shop. As a rough planning range for Central Florida condo buildings, expect a SIRS to run somewhere between $5,000 and $20,000 or more, with larger buildings (over 100 units, multiple structures, complex mechanical systems) pushing toward the higher end or beyond it. A few cost drivers worth knowing before you get quotes: - Square footage and number of buildings on the property (a single 40-unit tower costs less to inspect than a sprawling garden-style complex with eight separate structures)
- Access difficulty (parking garages, seawalls, and roof access all add inspection time)
- Whether you're bundling the SIRS with a milestone inspection, which can sometimes reduce duplicate site-visit costs since both may require similar structural access
- Documentation quality: if your association has clean records of prior repairs and original construction drawings, the engineer's job is faster and cheaper There's genuinely no statewide fee schedule, and DBPR doesn't set or cap pricing. Get at least two or three quotes from Florida-licensed engineers or architects before committing. Ask specifically whether the quote covers the full statutory component list under section 718.112(2)(g) or a narrower scope, because an underscoped study can leave your board thinking it's compliant when it isn't.
What was the deadline for the Orlando SIRS requirement, and did it change?
The original statutory deadline for condominium associations meeting the three-story, 3+ story threshold was December 31, 2024, under section 718.112(2)(g), Florida Statutes [1]. Buildings that reached their 25th year (30th if within 3 miles of the coast, though this coastal distinction applies more directly to milestone inspection timing) needed both the initial milestone inspection and the SIRS study by that date, with SIRS then updated at least every 10 years. Orange County and the broader Orlando area aren't coastal, so the 25-year milestone trigger (not the 30-year coastal version) is what typically applies to older Orlando-area condo towers. Check your building's certificate of occupancy date with the Orange County Building Division or your municipality's building department to confirm which year your building actually crossed the threshold. Florida lawmakers have adjusted SIRS-related deadlines and funding rules more than once since the original 2022 legislation (SB 4-D) passed after Surfside, including relief measures affecting how funding shortfalls get phased in. Because these rules keep moving, don't rely on last year's deadline summary, including this one, without confirming current status with your association's counsel. Our Florida condo reserve fund relief article tracks the legislative changes as they happen.
What happens if an Orlando condo association missed the SIRS deadline?
Missing the deadline doesn't erase the obligation. It just puts the association out of compliance while the requirement still applies. Associations that haven't completed a SIRS remain subject to the law's underlying funding requirements once the study is eventually completed, and boards can face difficulty with insurance renewal, mortgage lending (many lenders and Fannie Mae-adjacent underwriting now ask directly about SIRS status for condo project approval), and unit resale, since buyers and their lenders increasingly ask for SIRS documentation before closing. The practical fix is straightforward even if not cheap: get the study done now. A late SIRS is far better than no SIRS, both for legal exposure and for giving your board real numbers to plan a funding catch-up plan instead of guessing. Boards in this position should also loop in association counsel early, since the specific consequences (director liability exposure, insurer requirements, lender flags) depend on your building's specific history and your governing documents in ways a general article can't verdict for you. This is exactly the kind of judgment call that needs a licensed attorney familiar with your declaration, not a blog post.
Who is qualified to perform a SIRS in Florida?
Only a licensed engineer or licensed architect can perform the structural integrity reserve study itself, per section 718.112(2)(g), Florida Statutes [1]. You can verify a professional's license status directly through the Florida Department of Business and Professional Regulation's license search tool. A property management company, HOA software vendor, or reserve-planning consultant can (and often should) help your board organize the RFP process, collect prior inspection records, compare engineer quotes, and track the resulting deadlines and funding schedule. What they cannot legally do is perform the structural inspection or sign off on the remaining-useful-life estimates that make up the core of the study. This is the gap our $199 one-time Board Compliance Kit is built to fill. It doesn't replace the engineer. It organizes what your board does around the engineer's report (deadline tracking, document storage, owner communication templates, budget worksheets) so the actual license-holder's work gets used properly instead of sitting in a drawer.
Are HOA or condo special assessments tax deductible?
Generally, no, not for the owner personally, and this catches a lot of Florida condo owners off guard after a SIRS-driven special assessment lands. Regular HOA or condo assessments used for maintenance, operations, or reserve funding on your primary residence are treated by the IRS as a personal living expense, similar to a utility bill, and are not deductible. There are narrow exceptions worth knowing about, not general condo-owner deductions. If the unit is a rental or investment property, assessments allocable to the rental activity may be deductible as a rental expense; see IRS Publication 527 for rental property rules [2]. If you use part of your home for a legitimate home office, a proportional share might factor into that calculation. Special assessments that fund a capital improvement (rather than a repair) can sometimes be added to your cost basis, reducing capital gains tax when you eventually sell, rather than being deducted in the year paid. This is genuinely an area where a CPA familiar with real estate and rental property rules earns their fee. Don't guess on your own return, and don't rely on this paragraph as tax advice; confirm your specific situation with a tax professional, since deductibility depends heavily on how the property is used and titled.
How does a milestone inspection relate to the SIRS process in Orlando?
The two run on similar, but not identical, tracks and often get bundled by boards trying to save on engineer site visits. A milestone inspection, required under section 553.899, Florida Statutes, is a visual structural inspection at 25 years (30 if within 3 miles of the coast) and every 10 years after, focused on determining whether the building is structurally sound. A SIRS, required under section 718.112(2)(g), is triggered by the same age thresholds for condominium associations but is focused on reserve funding for the specific structural components, not a pass/fail safety determination. Orlando isn't a coastal jurisdiction, so most local buildings work off the 25-year threshold for both. Many Orlando engineering firms now offer combined milestone-plus-SIRS packages, since the site access, drawings review, and some of the physical inspection overlap. If your building needs both, ask upfront whether a bundled engagement reduces total cost versus hiring two separate firms for two separate visits. See our milestone inspections hub for the full breakdown of that separate, safety-focused requirement.
What should an Orlando board do first if it hasn't started a SIRS?
Start with your building's certificate of occupancy date, available from your county or municipal building department, to confirm exactly which statutory year your building crossed the 25-year mark. Don't guess based on when the association thinks the building opened. Get the actual date on record. Next, request quotes from at least two or three Florida-licensed engineering or architecture firms, and confirm each quote covers the full statutory component list, not a partial scope. Ask each firm for references from other Central Florida condo boards they've worked with recently, since SIRS demand has created a backlog at some firms. Once the study is in hand, the board's job shifts to funding: building a reserve schedule around the engineer's remaining-life and cost figures, communicating the resulting budget or assessment impact to owners clearly and early, and keeping documentation organized for the next required update (SIRS updates are required at least every 10 years). This is the administrative side, not the engineering side, and it's where boards most often drop the ball simply from lack of a system. Our reserve study for condo association guide walks through the funding-schedule math in more detail.
Frequently asked questions
What is a reserve study?
A reserve study is a professional assessment of a community's or building's major shared components (roofs, pavement, structural elements, mechanical systems) that estimates remaining useful life and replacement cost, then calculates how much money should be saved annually to cover future repairs without a surprise special assessment.
What is a reserve study for HOA communities specifically?
For an HOA (chapter 720 community, not a condo), a reserve study inventories common-element assets like roads, ponds, and clubhouse structures, and projects a savings schedule. Unlike condo SIRS requirements, most Florida HOAs are not legally required to commission one, though many boards do it voluntarily to avoid special assessments.
What is an HOA assessment?
An HOA assessment is the fee, usually monthly or quarterly, owners pay to fund the association's operating budget and reserve accounts. A special assessment is a separate, one-time charge levied when reserves or the operating budget can't cover an unexpected or under-planned expense.
How much should an HOA have in reserves?
Florida law sets no universal statutory percentage for HOA reserve funding under chapter 720. For condos under the SIRS mandate, structural components must be funded at 100% of the engineer-calculated need under section 718.112(2)(g), Florida Statutes. Beyond that mandatory piece, funding level is a board judgment call based on building age and risk tolerance.
How much does a reserve study cost?
For Florida condo SIRS studies, expect roughly $5,000 to $20,000 or more depending on building size, number of structures, and access complexity. There's no state fee schedule, so get multiple quotes from Florida-licensed engineers or architects before committing.
Are HOA or condo special assessments tax deductible?
Generally no, for a personal residence. Assessments are treated as a nondeductible personal living expense. Exceptions exist for rental properties (see IRS Publication 527) and for assessments that fund capital improvements, which may adjust your cost basis rather than being deducted upfront. Confirm with a CPA.
What is the difference between a SIRS and a milestone inspection?
A milestone inspection (section 553.899, F.S.) is a visual structural safety check at 25 or 30 years and every 10 years after. A SIRS (section 718.112(2)(g), F.S.) covers specific structural components for reserve funding purposes and locks in mandatory, non-waivable funding for those items once completed.
Does Orlando use the 25-year or 30-year milestone threshold?
Orlando and Orange County are inland, not coastal, so the 25-year threshold applies rather than the 30-year coastal exception under section 553.899, Florida Statutes. Confirm your building's exact age using the certificate of occupancy date on file with your county building department.
Who can legally perform a SIRS in Florida?
Only a Florida-licensed engineer or licensed architect can perform the study, per section 718.112(2)(g), Florida Statutes. You can verify any professional's active license status through DBPR's online license search before hiring them.
What happens if my Orlando condo missed the December 31, 2024 SIRS deadline?
The requirement doesn't go away. Late completion is better than none, but the association may face insurance, lending, and resale complications in the meantime. Get the study done as soon as possible and consult association counsel about your building's specific exposure.
Can a condo association vote to waive SIRS-based reserve funding?
No. Once a SIRS is completed, reserves for the structural components it covers can no longer be waived or reduced by membership vote under section 718.112(2)(f)4, Florida Statutes. This is different from non-structural reserve items, which may still be subject to a waiver vote depending on current law.
Is a SIRS required for HOAs (not condos) in Orlando?
No. The mandatory SIRS requirement under section 718.112(2)(g), Florida Statutes applies to condominium associations under chapter 718. Homeowners' associations under chapter 720 are not subject to this specific mandate, though a milestone inspection may still apply if the HOA has a qualifying building three stories or taller.
