Structural integrity reserve studies in St. Lucie County, FL

Last updated 2026-07-24

What is a reserve study?

A reserve study is a professional evaluation of a building's major common-area components (roof, structure, plumbing, electrical, paving, and similar systems) that estimates each item's remaining useful life and the cost to repair or replace it. The output is a funding schedule showing how much money the association should be setting aside each year so it has cash on hand when the roof or the parking garage actually needs work, instead of hitting owners with a surprise bill. In Florida, there are two related but distinct things people mean by "reserve study." The general reserve study, historically optional for condo and HOA boards to fund at 100% (many voted to waive or underfund it), covers everything from paint to elevators. The structural integrity reserve study, or SIRS, is a narrower, statutorily mandatory subset created after the Champlain Towers South collapse in Surfside in June 2021. SIRS covers only the load-bearing and life-safety components: roof, load-bearing walls, primary structural members, floor and foundation, fireproofing and fire protection systems, plumbing, electrical, and waterproofing, among others listed in the statute ^[1]. The practical difference matters for a St. Lucie County board: SIRS items cannot be waived, cannot be underfunded, and cannot be pooled with other reserve categories starting with reports and budgets due after the transition period set by the legislature. General reserve items still allow more flexibility.

What is a reserve study for an HOA (versus a condo)?

Homeowners' associations (single-family and townhome HOAs governed by F.S. 720) are not currently subject to the SIRS mandate. SIRS applies to condominium associations under F.S. 718 and cooperative associations under F.S. 719, specifically to residential buildings three stories or more in height ^{[1] [2]}. If your community is a traditional HOA with detached homes, you don't have a SIRS deadline, though a general reserve study is still smart practice for roads, drainage, clubhouses, and pools. Where it gets confusing in St. Lucie County: some communities blend condo-style buildings with HOA-style governance, or have multiple 3-story-plus buildings inside a larger HOA-style master association. If your community includes any residential condominium building of three stories or more, that condominium association (not the master HOA) is the one on the hook for SIRS. Check with your association's counsel to confirm which entity holds the SIRS obligation, since ownership structure and governing documents vary.

What is an HOA assessment (and what is an HOA special assessment)?

An assessment is simply the fee owners pay to fund the association's operations and reserves. Regular assessments are the recurring monthly or quarterly dues everyone budgets for. A special assessment is a one-time or short-term extra charge the board levies when the regular budget and reserves can't cover a specific cost, commonly a big repair, an insurance shortfall, or (increasingly, post-Surfside) a structural repair identified by a milestone inspection or SIRS. Florida condo boards get their assessment authority from F.S. 718.116 and their specific association's declaration and bylaws. The board doesn't need a membership vote to levy most special assessments unless the governing documents require one, which is why many owners are caught off guard. If a SIRS in St. Lucie County turns up a deteriorating structural member, the board can typically levy a special assessment to fund the fix without waiting for an annual meeting, though notice requirements still apply under 718.112 for the meeting where the assessment is discussed ^[1]. For a deeper walkthrough of how these assessments get calculated and challenged, see hoa special assessment.

How much should an HOA (or condo) have in reserves?

There's no single dollar figure or percentage that fits every building; the honest answer is "whatever the reserve study says your specific components need," because a 1975 4-story building on the barrier island faces different costs than a 2005 8-story tower a mile inland. That said, for condo associations subject to SIRS, the statute is now specific about the mechanism: reserves for SIRS-covered components must be funded based on the study's projected costs, with no ability to waive or underfund those line items starting with the fiscal year after the association's first SIRS is completed ^[1]. A widely used industry rule of thumb, from reserve study professionals (not a statutory requirement), suggests reserves should be funded to at least 70% of the "fully funded" ideal to avoid special assessment risk, though many well-run associations target 100%. Florida's own guidance doesn't set that percentage; it's an industry benchmark referenced by reserve specialists and the Community Associations Institute. What Florida law does set is the SIRS mechanism itself: no waivers, no pooling, and funding tied to the study's cost estimates for those specific structural items ^[1]. For a broader look at how the 2022-2023 legislative changes affect funding obligations statewide, see florida condo reserve fund relief.

How much does a reserve study cost in St. Lucie County?

Small condo, 3-4 stories, under 50 units	$1,500 to $4,000
Mid-size condo, 5-10 stories, 50-150 units	$4,000 to $10,000
Large or high-rise, 150+ units or complex structure	$10,000 to $15,000+	These figures come from reserve study firms and engineering consultants operating statewide; there's no official DBPR fee schedule, so treat this as a planning range, not a quote. Coastal buildings in St. Lucie County (Hutchinson Island especially) often land at the higher end because salt air accelerates corrosion in rebar and metal fasteners, meaning the inspecting engineer has more deterioration to document and more destructive or semi-destructive testing to justify. The study itself must be performed or supervised by a licensed engineer or architect under F.S. 718.112(2)(g), so the cost reflects professional liability and site time, not paperwork. A board that tries to save money with a bargain-bin "reserve study" that skips the required professional inspection component is setting itself up for a report that doesn't satisfy the statute. For more on scope and what a compliant study includes, see reserve study for condo association.

Costs vary by building size, number of components, and whether you're getting a full SIRS (which requires inspection by a licensed engineer or architect) versus a general reserve study. Statewide pricing data (Florida doesn't publish official SIRS fee schedules) generally runs: | Building type | Typical SIRS cost range |

What is a SIRS and how is it different from a milestone inspection?

A milestone inspection and a SIRS are two separate, related requirements that often get confused because they were both created (or accelerated) by the same 2022 legislative response to the Surfside collapse. A milestone inspection is a one-time (then recurring every 10 years) structural inspection by a licensed engineer or architect, required for condo and co-op buildings 3 stories or taller once the building hits 30 years old (or 25 years old if within 3 miles of the coast), under F.S. 553.899 ^[3]. It produces a phase one (and if needed, phase two) inspection report on the building's structural condition. A SIRS is the funding-side companion: a reserve study specifically for the structural components the milestone inspection (and general engineering assessment) identifies, required under F.S. 718.112(2)(g) for condo associations with buildings 3 stories or more, regardless of the building's distance from the coast ^[1]. Every residential condo building 3 stories and up needs a SIRS; only buildings meeting the 25-year (coastal) or 30-year (inland) age threshold need the milestone inspection. Much of St. Lucie County, including barrier island communities on Hutchinson Island, falls within the statute's coastal definition (within 3 miles of the coastline), which triggers the 25-year milestone threshold rather than 30. Boards should confirm the exact distance determination and applicable deadline with their county building department and association counsel, since coastal mileage measurement can be a point of dispute.

When is the SIRS deadline for condo associations in St. Lucie County?

The statute set December 31, 2024 as the original deadline for existing condo and cooperative associations to complete their first SIRS, with the state legislature later adjusting timelines and adding some flexibility for associations that show good-faith progress ^{[1] [1]}. Boards that haven't completed a SIRS should treat this as urgent, not optional, because the funding and disclosure obligations that follow (mandatory reserve line items, no more waivers on structural components) all key off the SIRS completion date. St. Lucie County follows the same statutory statewide deadline; there's no county-specific extension or ordinance overriding the state timeline. If your association manager or board hasn't scheduled the required licensed engineer or architect inspection, that's the first call to make, not the reserve study firm. The inspection and the reserve study for SIRS purposes typically get bundled through firms that offer both services, but the statute requires the SIRS to be based on that engineering inspection, not a desktop estimate. Boards juggling both a milestone inspection and a SIRS deadline in the same window (common for coastal buildings hitting the 25-year mark) should confirm with counsel which report needs to be filed with the county building official versus which stays internal for owner disclosure and budgeting purposes.

Are HOA and condo special assessments tax deductible?

Generally, no, not for individual homeowners' personal federal income tax returns, and this is one of the most common misunderstandings boards run into after a big assessment. Special assessments used for capital improvements, structural repairs, or reserve shortfalls are treated by the IRS as additions to the cost basis of the unit, not as a deductible expense, similar to how a kitchen renovation isn't deductible but does raise what you can subtract from a future capital gain when you sell ^[4]. There are narrow exceptions. If a unit is a rental property, a portion of assessments tied to repairs (not capital improvements) may be deductible as a rental business expense on Schedule E, and IRS guidance on repairs versus improvements (Publication 527 for residential rental property) governs which bucket an expense falls into ^[5]. A board can't give owners tax advice, and shouldn't try; direct owners to a CPA, especially for larger special assessments where the repair-versus-improvement distinction has real dollar consequences. For day-to-day board members, the practical point is this: don't market a special assessment to owners as "tax deductible" as a way to soften the blow. It's misleading for most owner-occupants, and if it's wrong, it's the board's credibility on the line, not the IRS's.

What should a St. Lucie County board do first if it hasn't started SIRS?

Start with the licensed professional, not the paperwork. Contact a Florida-licensed engineer or architect experienced in SIRS and milestone work, get on their schedule (many firms in the Treasure Coast region are backlogged given statewide demand), and get a written proposal that separately scopes the milestone inspection (if applicable) and the SIRS. While that's underway, the board should pull together everything the inspector and reserve analyst will need: prior engineering reports, permit history, any known leak or corrosion complaints, insurance claims history, and the current reserve schedule. Boards that show up to the inspection with organized records tend to get faster, cheaper, more accurate reports, because the engineer isn't burning billable hours reconstructing building history from scratch. This is the kind of organizing work our $199 Building-Specific Board Compliance Kit is built for: it doesn't replace the licensed engineer's inspection or the reserve specialist's analysis (those have to be done by the professionals the statute requires), but it gives your board a structured way to track deadlines, assemble the records those professionals need, and communicate the timeline and cost estimates to owners without a $400-an-hour lawyer drafting every email. Find it at /board-kit-builder. Boards should also loop in association counsel early, particularly around notice requirements for the meeting where SIRS results and any resulting special assessment get discussed, since F.S. 718.112 has specific disclosure rules for that meeting ^[1].

Where do I find the exact statutes governing reserve studies and SIRS in Florida?

The primary statute is Florida Statutes Chapter 718, specifically section 718.112(2)(g), which defines SIRS, lists the required structural components, and sets the funding and waiver rules ^[1]. The milestone inspection requirement is in a separate section, F.S. 553.899, administered alongside local building officials ^[3]. Cooperative associations have a parallel provision in F.S. 719. The Department of Business and Professional Regulation (DBPR), specifically its Division of Florida Condominiums, Timeshares, and Mobile Homes, is the state agency that licenses community association managers and provides regulatory guidance on these requirements, though it does not set county-level deadlines ^[6]. Statutes get amended almost every legislative session on this topic; a board should confirm current requirements with its association's counsel and, for milestone inspection building-code specifics, with the St. Lucie County building department, rather than relying on any single year's snapshot of the law.

Frequently asked questions

What is a reserve study for an HOA?

It's a professional analysis estimating the remaining life and replacement cost of an association's major shared components, like roofs, paving, and pools, used to set annual reserve contributions. For Florida condos, a parallel but mandatory version called a SIRS covers only structural and life-safety components under F.S. 718.112, and can't be waived like general reserves can.

What is an HOA assessment?

An assessment is the fee owners pay an association, either as a recurring regular assessment covering operating budgets and reserves, or as a special assessment, a one-time extra charge levied when the regular budget can't cover a specific cost like a structural repair or insurance shortfall.

How much should an HOA have in reserves?

There's no fixed percentage in Florida law for general HOA reserves; the amount should match what a professional reserve study estimates for that community's specific components. For condo SIRS components specifically, Florida law requires full funding based on the study's projected costs, with no waivers allowed, under F.S. 718.112.

How much does a reserve study cost?

Statewide ranges typically run $1,500 to $4,000 for small buildings, $4,000 to $10,000 for mid-size condos, and $10,000 to $15,000 or more for large or structurally complex buildings, based on data from reserve study and engineering firms. Coastal St. Lucie County buildings often land toward the higher end due to added corrosion inspection and testing.

Are HOA special assessments tax deductible?

Generally no, for owner-occupants. The IRS typically treats special assessments for capital improvements or repairs as additions to a property's cost basis rather than a deductible expense, per general IRS guidance on rental and personal property. Rental property owners may deduct a portion tied to repairs; consult a CPA for specifics.

Does St. Lucie County have its own SIRS deadline separate from the state?

No. St. Lucie County follows the statewide deadline set in F.S. 718.112, originally December 31, 2024 for existing associations' first SIRS, with legislative adjustments possible in later sessions. There's no county ordinance creating a separate local deadline; confirm current dates with your association's counsel.

What buildings in St. Lucie County need a milestone inspection versus a SIRS?

Any condo or co-op building 3 stories or taller needs a SIRS, per F.S. 718.112, regardless of age. Only buildings that are 30 years old (or 25 years old if within 3 miles of the coast) need the separate milestone inspection under F.S. 553.899. Much of coastal St. Lucie County falls under the 25-year threshold.

Who is legally allowed to perform a SIRS in Florida?

The structural inspection portion must be performed by a Florida-licensed engineer or architect, per F.S. 718.112(2)(g). The reserve funding analysis is often completed by the same firm or a partnered reserve study specialist using that engineering report as the technical basis; a desktop estimate without the licensed inspection doesn't satisfy the statute.

Can a condo association waive or underfund SIRS reserves?

No, not for the components the statute defines as SIRS items. Once an association completes its first SIRS, F.S. 718.112 prohibits waiving or pooling reserve funding for those structural components going forward, unlike general reserve items which historically allowed a membership vote to waive or underfund.

What happens if a St. Lucie County condo board misses the SIRS deadline?

Consequences can include exposure to owner lawsuits, difficulty obtaining insurance or financing, and potential regulatory scrutiny from DBPR, though the exact enforcement mechanism has shifted across legislative sessions. Boards behind schedule should engage a licensed engineer immediately and consult counsel about disclosure obligations to owners in the meantime.

Is a reserve study the same thing as a milestone inspection report?

No. A milestone inspection report documents a building's structural condition at a point in time, produced under F.S. 553.899. A reserve study, including the SIRS version, is a funding document that uses inspection findings to project repair costs and timelines and sets the association's savings schedule under F.S. 718.112.

How often does a condo association need to redo its SIRS?

The statute requires SIRS to be updated at least every 10 years, aligning roughly with the milestone inspection cycle for buildings that require both, though associations often update reserve figures more frequently as part of annual budgeting. Confirm the exact recurrence requirement with your association's counsel, as legislative language has been refined across sessions.
