TL;DR
"RCW condo reserve study" refers to Washington's Revised Code of Washington, not Florida law. If your building is in Florida, the controlling rule is Florida Statutes chapter 718.112(2)(g), which requires a Structural Integrity Reserve Study (SIRS) for condos 3 stories or taller, plus reserve funding for specific components. This article explains both frameworks and what Florida boards must actually do.
What does "RCW" mean, and why does it show up in condo reserve searches?
RCW stands for Revised Code of Washington, the codified state law for Washington State. It has nothing to do with Florida. If you searched "RCW condo reserve study" while sitting on a Florida board, you likely got pulled in by a general web search that doesn't know your state, or you saw the term on a national HOA forum and assumed it was universal shorthand. It isn't. Washington's reserve study law lives in RCW 64.34.380 (for condos) and related sections of the Washington Uniform Common Interest Ownership Act. It requires associations to prepare and update reserve studies and requires certain disclosures to unit owners and buyers [1]. That's a real, separate legal system with its own thresholds, its own definitions, and its own enforcement. Florida has no "RCW." Florida's equivalent body of law is the Florida Statutes, and the condo-specific chapter is Florida Statutes Chapter 718, the Condominium Act [2]. If you manage or sit on a board for a building in Florida, RCW simply doesn't apply to you, full stop. What does apply is F.S. 718.112, and since 2022 that section has gotten a lot more demanding for taller buildings. This mix-up is common enough that it's worth spelling out clearly, because the consequences of using the wrong state's rule are not small. A board that budgets based on Washington's older reserve study cadence, or assumes Florida has the same voluntary waiver options Washington historically allowed, could walk straight into a statutory violation or an underfunded reserve account right when a special assessment lands.
What is a reserve study?
A reserve study is a professional engineering and financial assessment that identifies an association's major shared components (roofs, structure, plumbing, elevators, pavement, and similar systems), estimates their remaining useful life, and calculates how much money the association needs to save each year to pay for repair or replacement without a surprise special assessment. A basic reserve study has two parts: a physical analysis (what needs replacing, and when) and a financial analysis (how much cash the association currently has versus how much it needs, and what contribution rate closes that gap). Most studies get updated every few years because material costs, inflation, and component wear don't stand still. In Florida, the newer version of this document for condominiums 3 stories or more is called a Structural Integrity Reserve Study, or SIRS. It's more than a nice-to-have anymore. Florida Statutes 718.112(2)(g) requires condo associations meeting the height and age thresholds to complete one, and it dictates which components must be included: roof, load-bearing walls, primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, and windows and exterior doors, among others named in the statute [3]. A SIRS has to be performed or verified by a licensed engineer or architect [3]. For a full walkthrough of what a study covers and how it's built, see our reserve study guide.
What is a reserve study for an HOA?
For a homeowners association (as opposed to a condo association), a reserve study serves the same purpose: figure out what shared components the HOA is responsible for (think clubhouse roofs, pool equipment, private roads, retention ponds, gates) and plan funding so replacement costs don't blindside owners with a special assessment. The legal requirements differ from condos, though. Florida's HOA statute, Chapter 720, does not currently impose the same SIRS mandate that Chapter 718 imposes on condominiums 3 stories and up [4]. Many HOAs still choose to commission a reserve study voluntarially because lenders, insurers, and prospective buyers increasingly ask for one, and because it's simply good governance to know your true future costs. If your community has multi-story residential buildings that happen to be condominiums within an HOA-governed development, check which statute actually applies to those buildings, since it may still be Chapter 718. See our dedicated HOA reserve study explainer for a state-by-state comparison of what's required and what's just recommended.
What is an HOA assessment, and what is a special assessment?
An assessment is the periodic fee owners pay to fund the association's operating budget and reserves. Most owners know this as their monthly or quarterly dues. A special assessment is a separate, usually one-time charge levied outside the regular budget, typically because reserves fell short of an actual repair bill, or because a big-ticket item (roof, seawall, structural repair) came due faster than anticipated. Special assessments are legal and common in Florida condos, especially post-Surfside. Florida Statutes 718.116 governs assessments generally, including how they're levied and collected [5]. The statute doesn't cap the size of a special assessment; a board can levy what's needed to cover a documented expense, subject to the association's governing documents and any required membership vote thresholds. If your board is staring down a special assessment right now, our HOA special assessment guide walks through notice requirements, vote thresholds, and payment plan options, and condo special assessment insurance covers whether insurance products can soften the blow.
How much should an HOA (or condo) have in reserves?
There's no single dollar figure that's "enough," because it depends entirely on your building's age, component inventory, and replacement costs. The honest answer is: enough to fully fund the schedule your reserve study or SIRS produces, which is a component-by-component number, not a round percentage. That said, industry benchmarks exist. The Community Associations Institute and reserve study professionals commonly cite "percent funded" as the metric: reserves divided by the fully funded balance the study calculates for that point in time. A commonly cited healthy target is 70% funded or higher, with anything under 30% considered a red flag for pending special assessments, though these are industry conventions from reserve specialists rather than a Florida statutory threshold [6]. For Florida condos under the post-2022 law, the practical floor isn't a percentage at all. Florida Statutes 718.112(2)(f) requires that reserves for the SIRS-covered components be funded based on the study's findings, and it eliminates the ability of unit owners to vote to waive or reduce reserves for those specific structural components (waivers for other, non-structural reserve items are still allowed under narrower conditions) [3]. In plain terms: for roofs, load-bearing walls, and the other listed structural items, the board can't just vote to skip saving the money anymore, the way many associations did for decades before Surfside. If you're trying to benchmark your own numbers, our reserve study for condo association piece has worked funding-schedule examples.
How much does a reserve study cost in Florida?
Cost varies by building size, number of components, and whether you need a full SIRS (which requires a licensed engineer or architect) versus a general voluntary reserve study. As a rough range reported by reserve study firms and condo trade groups, a basic reserve study for a small to mid-size condo association can run somewhere in the low thousands of dollars, while a full SIRS for a larger high-rise with a detailed structural component list, on-site inspection, and engineering sign-off commonly runs several thousand dollars and up, scaling with square footage and building complexity. Because pricing isn't standardized statewide and DBPR doesn't set fee schedules for private engineering services, the only reliable way to get a real number is to request quotes from licensed engineers or reserve specialists who serve your county. Ask each bidder to confirm they meet the licensing and component requirements under Florida Statutes 718.112(2)(g) before you sign anything [3]. Where the reserve study and SIRS overlap with the separate Milestone Inspection requirement under Florida Statutes 553.899 is worth understanding too, since some boards bundle the two engagements to save on site visits, though they're legally distinct deliverables answering different questions [7].
Are HOA or condo special assessments tax deductible?
Generally, no, not for the individual unit owner paying it, in most ordinary circumstances. The IRS treats special assessments for capital improvements to your primary residence the same way it treats other capital improvements: they typically aren't deductible in the year paid, but they may increase your cost basis in the property, which can reduce capital gains tax when you eventually sell [8]. There are narrow exceptions. If the unit is a rental property, special assessments tied to repairs and maintenance may be deductible as a business expense in the year incurred, or depreciated if they count as a capital improvement, subject to normal IRS depreciation rules for rental real estate [9]. If a special assessment funds casualty-loss repairs tied to a federally declared disaster, there may be separate casualty-loss deduction rules to look into. None of this is tax advice specific to your situation. Every owner's facts differ (primary residence versus rental, itemizing versus standard deduction, state of residence), so this is squarely a question for a CPA or tax attorney, not a board decision.
What Florida-specific reserve rules should a board actually track?
Here's the short list that matters if your building is 3 stories or taller in Florida: Milestone inspection trigger: Florida Statutes 553.899 requires buildings 3 stories or more to complete a Milestone Structural Inspection, generally at 30 years from certificate of occupancy (25 years if within 3 miles of the coast), and every 10 years after [7]. SIRS requirement: Florida Statutes 718.112(2)(g) requires condo associations meeting the same 3-story threshold to complete a Structural Integrity Reserve Study, initially due by December 31, 2024 for most associations, then every 10 years [3]. No more full waivers on structural reserves: the 2022 and 2023 legislative changes (following SB 4-D and later amendments) removed the ability to waive or reduce reserve funding for the SIRS-designated structural components [3]. Reserve fund relief options: some limited relief and phase-in provisions have been debated and adjusted at the state level since 2023; check current status, since legislative sessions have amended deadlines and funding phase-ins more than once. Our florida condo reserve fund relief page tracks the latest changes. Because the legislature has amended these deadlines before and may again, confirm current dates and dollar thresholds with your association's counsel and your county building department before finalizing a budget or vote.
How does Florida's rule compare to Washington's RCW reserve study rule?
| Feature | Florida (F.S. 718.112) | Washington (RCW 64.34.380 et al.) | |
|---|---|---|---|
| Applies to | Condos 3+ stories | Condos generally, per WUCIOA | |
| Study required | Yes, SIRS for structural components [3] | Yes, reserve study with periodic update [1] | |
| Waiver allowed | No, for SIRS structural items [3] | Historically more flexible opt-out/underfunding provisions exist under Washington law | |
| Licensed professional required | Yes, engineer or architect for SIRS [3] | Reserve study preparer requirements set under Washington law, not always requiring a PE | |
| Milestone structural inspection | Yes, separate requirement, F.S. 553.899 [7] | No equivalent statewide milestone inspection statute | The upshot: Florida's post-Surfside framework is now stricter in one specific way, structural reserve items can't be waived, and it layers a separate physical inspection law on top of the financial reserve study. Washington's system focuses more on disclosure and periodic study updates without an equivalent forced physical inspection regime tied to building age and coastal distance. |
What happens if a Florida association ignores these deadlines?
Consequences vary by which requirement gets missed, but none of them are good. Missing the SIRS deadline can expose the association to claims that it breached its statutory duty to fund reserves properly, which can matter in a later dispute with unit owners or buyers relying on disclosure documents. Missing a Milestone Inspection deadline can trigger local code enforcement action from the county or municipality building department, since 553.899 gives local governments enforcement authority over the inspection timeline [7]. Selling a unit also gets harder. Florida law requires certain SIRS-related disclosures to prospective buyers, and title companies and lenders increasingly ask for proof of Milestone Inspection and SIRS completion before closing, particularly after several Florida counties tightened lending practices post-Surfside. None of this means a board has to panic-hire the first engineer who calls. It means building a real timeline: know your building's certificate-of-occupancy date, know your distance from the coast, know your SIRS due date, and get quotes early instead of scrambling in month 11. A Building-Specific Board Compliance Kit ($199 one-time) is built to help boards organize exactly this timeline, the milestone date, the SIRS date, and the required disclosures, without replacing the licensed engineer's actual inspection work, which only a licensed professional can perform under Florida law.
Where can a board verify the current rules directly?
Don't take any single article's word for the exact dollar thresholds or deadline dates, including this one, since the legislature revisits these sections almost every session. Go to the primary sources: the full text of Florida Statutes Chapter 718 is on flsenate.gov [2], and the Department of Business and Professional Regulation's Division of Florida Condominiums, Timeshares, and Mobile Homes publishes guidance and licensing information relevant to community association managers at myfloridalicense.com [10]. Your association's counsel should confirm how the current version of 718.112 and 553.899 apply to your specific building's certificate-of-occupancy date, height classification, and coastal distance, since those three facts drive every deadline calculation. County building departments also maintain their own milestone inspection portals in some jurisdictions, and those local records control for enforcement purposes even when they simply mirror the state statute.
Frequently asked questions
What is a reserve study?
A reserve study is a professional assessment, usually combining engineering and financial analysis, that identifies an association's major shared components, estimates when each needs repair or replacement, and calculates the savings rate needed to pay for it without a surprise special assessment. Florida's condo version for taller buildings is called a SIRS, required under Florida Statutes 718.112(2)(g).
What is a reserve study for an HOA?
For an HOA, a reserve study identifies shared components like clubhouses, pools, roads, and gates, and projects funding needed for their eventual replacement. Florida's Chapter 720 doesn't currently mandate a SIRS-style study for HOAs the way Chapter 718 does for condos 3+ stories, though many HOAs commission one voluntarily for lender and insurer requirements.
What is an HOA assessment?
An HOA assessment is the regular fee (monthly, quarterly, or annual) owners pay to fund operations and reserves. A special assessment is a separate, usually one-time charge levied when reserves or the operating budget can't cover an unexpected or underfunded cost, such as a roof replacement or structural repair.
How much should an HOA have in reserves?
There's no universal dollar figure; it depends on your component inventory and replacement costs per your reserve study. Reserve professionals commonly cite 70% funded (reserves divided by fully funded balance) as a healthy target and under 30% as a red flag, though these are industry benchmarks, not Florida statutory requirements.
How much does a reserve study cost?
Costs vary widely by building size and scope. Basic voluntary reserve studies for smaller associations often run in the low thousands of dollars; a full Florida SIRS requiring a licensed engineer or architect and detailed structural component review for a larger high-rise typically costs more, scaling with square footage. Get multiple quotes since Florida doesn't set a standard fee.
Are HOA special assessments tax deductible?
Generally no, for a primary residence, though the amount may add to your cost basis and reduce capital gains tax on a future sale. Rental property owners may deduct or depreciate certain special assessment costs as a business expense. This varies by individual tax situation, so confirm with a CPA.
What does RCW mean and does it apply to Florida condos?
RCW stands for Revised Code of Washington, that state's codified laws, including its condo reserve study requirements under RCW 64.34.380 and the Washington Uniform Common Interest Ownership Act. It has no legal effect in Florida. Florida condo reserve and inspection rules come from Florida Statutes Chapter 718 and 553.899 instead.
What is a SIRS in Florida condo law?
SIRS stands for Structural Integrity Reserve Study, required under Florida Statutes 718.112(2)(g) for condominium associations with buildings 3 stories or taller. It must cover specific structural components like roof, load-bearing walls, and plumbing, and must be performed or verified by a licensed engineer or architect.
Can a Florida condo association still waive reserve funding?
Not for the structural components covered by the SIRS. Since the 2022 legislative changes following Senate Bill 4-D, unit owners can no longer vote to waive or reduce reserve funding for SIRS-designated items like roofs and load-bearing walls under Florida Statutes 718.112(2)(f). Waivers for other, non-structural reserve items may still be possible under narrower conditions; confirm current rules with counsel.
Is a Milestone Inspection the same thing as a reserve study?
No. A Milestone Structural Inspection under Florida Statutes 553.899 is a physical structural inspection of the building at 30 years (25 if near the coast) and every 10 years after. A SIRS is a financial and component-planning study under 718.112. They're often scheduled together but are legally separate requirements with different deliverables.
When is Florida's SIRS deadline?
The initial SIRS deadline for most qualifying condo associations was December 31, 2024, with updates required every 10 years afterward under Florida Statutes 718.112(2)(g). Legislative sessions have adjusted related phase-in and funding provisions before, so confirm the current deadline with your association's counsel and county.
Does Florida require reserve studies for all HOAs, or just condos?
Florida's mandatory SIRS requirement under Chapter 718 applies specifically to condominium associations with buildings 3 stories or more. Chapter 720, which governs most single-family HOAs, doesn't currently impose the same mandatory structural reserve study, though voluntary reserve studies are common and often requested by lenders or insurers.
