TL;DR
Washington's Condominium Act (RCW 64.34) requires most condo associations, including those in Burien, to get a reserve study covering a 30-year period and update it every three years. Reserve studies typically cost $3,000 to $8,000 depending on building size, and boards use them to set reserve contributions that avoid special assessments.
What is a reserve study?
A reserve study is a physical inspection and financial analysis of a condo or HOA's shared components, roofs, siding, elevators, parking structures, plumbing, paving, done by a qualified provider who estimates when each item will need repair or replacement and how much that will cost. The final report gives the board two things: a physical component list with remaining useful life, and a funding plan showing how much money the association should be setting aside each year. Most studies split into two phases. A full or Level I study includes an on-site inspection, component inventory, and 20 to 30 year funding schedule. An update study (sometimes called Level II or III) reuses the prior inventory and adjusts costs and timelines without a full site walk. Associations typically get a full study every five to six years with update studies in between, though Washington's statute sets its own minimum cadence, discussed below. The report is not a maintenance plan and it is not an engineering inspection of structural safety. It is a budgeting tool. Boards in taller buildings or older concrete structures sometimes need a separate structural or engineering assessment on top of the reserve study, particularly if there's visible cracking, water intrusion, or age-related deterioration of concrete and rebar. If you're comparing this to what Florida boards face, the core concept, inventory plus funding plan, is the same, but Florida layers on a mandatory structural inspection (the Milestone Inspection) and a Structural Integrity Reserve Study (SIRS) with legally required, non-waivable reserve funding for specific components. Washington's law is less prescriptive on the structural side. See our reserve study explainer for the baseline mechanics and reserve study for condo association for how Florida's version differs.
What is a reserve study for an HOA (and how is it different from a condo study)?
A reserve study for an HOA covers common-area assets the homeowners association owns and maintains, think clubhouse roofs, private roads, retention ponds, pool equipment, community fencing, rather than the building components inside individual condo units. The methodology is identical to a condo reserve study: inventory the components, estimate remaining life, model the funding curve. The difference is just what gets inventoried. In a single-family HOA, unit owners typically maintain their own home's roof and structure, so the reserve study only covers shared amenities. In a condominium, the association usually owns and must reserve for the building envelope, roof, and often mechanical systems serving multiple units, which makes condo reserve studies larger and more expensive per unit than HOA studies covering the same number of homes. Washington's Condominium Act, RCW 64.34, and the Washington Uniform Common Interest Ownership Act, RCW 64.90 (which applies to associations created after July 1, 2018, and some older ones that opt in), both require reserve studies for common interest communities, condo and planned-community HOAs alike, with only a few exemptions for very small associations. See hoa reserve study for a broader comparison of how states structure this requirement.
Does Washington law actually require a reserve study for Burien condos?
Yes. Under RCW 64.34.380, condominium associations in Washington must have a reserve study prepared unless the declaration exempts them or the association meets a narrow small-association exception. The statute requires the study to be updated at least every three years, and the board must review and, if needed, update the reserve study annually [1]. The statutory language is specific about what the study must cover: "a reserve study shall include, at a minimum... a reserve funding plan that recommends how the association may fund the reserves" and a component list identifying useful life and remaining useful life estimates and current repair or replacement costs [1]. Boards in Burien, which sits in King County and falls under the same statewide statute as every other Washington condo, don't get a local carve-out. City limits don't change the state law requirement. Washington also requires disclosure. Under RCW 64.34.410 and the related resale certificate statute, sellers must disclose the reserve study status and current reserve fund balance to buyers, so an outdated or missing study can slow down or complicate unit sales. If your association is unsure whether it qualifies for an exemption, that's a question for association counsel, not a DIY read of the statute, because exemption language and small-association thresholds get interpreted differently county to county.
How much does a reserve study cost?
Expect to pay $3,000 to $8,000 for a full reserve study on a typical mid-size condo building (20 to 100 units), with larger or more complex buildings, multiple structures, elevators, underground parking, running higher. Update studies that reuse an existing component inventory usually cost $500 to $2,000 less than a full study because they skip the full site inspection. Pricing varies by: - Number of buildings and total unit count
- Whether the provider does an on-site physical inspection or a desktop update
- Complexity of shared systems (elevators, fire suppression, underground garage, pool)
- Whether a licensed engineer needs to be involved for structural components There's no national database that publishes verified per-project reserve study costs, so treat any specific number, including the range above, as a planning estimate rather than a guaranteed quote. Get at least two or three bids from providers who are members of the Community Associations Institute's Reserve Specialist (RS) credential program or hold the Professional Reserve Analyst (PRA) designation, since credentialing signals the provider follows a recognized methodology. Compare that cost to what happens without a study: an association that under-reserves for ten years and then faces a $40,000 roof replacement has to either drain operating funds or hit owners with a special assessment. A $5,000 study every three to five years is cheap insurance against that outcome. For the Florida-specific cost comparison and how SIRS pricing runs higher due to engineer sign-off requirements, see reserve study for condo association.
How much should an HOA (or condo) have in reserves?
| 70% or higher | Strong; low special assessment risk | |
|---|---|---|
| 30% to 70% | Fair; some risk of assessments for larger items | |
| Under 30% | Weak; high risk of special assessments or deferred maintenance | These bands come from industry practice popularized by reserve study firms and referenced in Community Associations Institute educational materials; they are not a legal standard and no state statute mandates a specific percent-funded target for HOAs. Some associations run intentionally low reserves and use "pay as you go" special assessments instead, a strategy the reserve study field usually cautions against because it front-loads cost onto whoever owns during the assessment year rather than spreading it fairly across owners over time. Boards should ask their reserve study provider for the percent funded figure explicitly. If it's under 30%, that's the moment to have a real conversation with owners about phased dues increases versus a lump-sum special assessment later. |
There's no single dollar figure that applies to every association, because the right reserve balance depends entirely on your components, their age, and their replacement cost, not on unit count or building size alone. What matters is the percent funded metric: your current reserve balance divided by the total that should be on hand today given component depreciation. Reserve study professionals generally describe funding levels on a scale like this: | Percent funded | General assessment |
What is an HOA assessment (and what is a special assessment)?
An HOA assessment is the regular fee owners pay to the association, usually monthly or quarterly, covering operating expenses (landscaping, insurance, management fees) and a contribution to the reserve fund. This is sometimes just called "dues" but the legal term in most governing documents and state statutes is "assessment." A special assessment is a one-time or limited-duration additional charge the board levies outside the regular assessment, usually to cover a shortfall for a specific project, an emergency repair, an underfunded reserve, or a legal judgment. Most condo declarations and state statutes require board approval and, above certain dollar thresholds, membership notice or a vote. Washington's RCW 64.34.360 gives the board authority to levy assessments including special assessments for reserves, subject to the declaration's own limits on amount and process. The practical difference for owners: regular assessments are predictable and budgeted; special assessments often arrive with little warning and can range from a few hundred dollars to tens of thousands per unit depending on the project. A well-funded reserve is the main tool boards have to avoid special assessments becoming the default funding mechanism. See hoa special assessment for a detailed breakdown of notice requirements and payment plan obligations that show up across states.
Are HOA special assessments tax deductible?
Generally, no, not for the individual homeowner claiming it on a personal tax return, if the assessment funds capital improvements or reserves for the building rather than deductible operating costs. The IRS treats special assessments for improvements to the property (a new roof, a repaved parking lot, structural repairs) as an addition to your cost basis in the property, not as a current-year deduction [2]. There are narrow exceptions. If you rent out the unit as investment property, a portion of certain special assessments may be depreciable or deductible as a business expense, and assessments tied to casualty losses in a federally declared disaster area can sometimes qualify for a casualty loss deduction under IRC Section 165, subject to strict rules [2]. None of this is a substitute for advice from a CPA who has your actual assessment notice and closing documents in front of them; tax treatment turns on specifics (owner-occupied versus rental, what the assessment actually funds, whether it's a casualty loss) that a general article can't resolve for your situation. The safest approach: keep every notice, invoice, and board resolution related to a special assessment. Even when it's not deductible now, it adjusts your basis and matters when you sell.
How is Washington's reserve study law different from Florida's SIRS requirement?
| Reserve study required | Yes, for most condos [1] | Yes, SIRS for buildings 3+ stories [4] | |
|---|---|---|---|
| Update frequency | At least every 3 years [1] | Every 10 years [4] | |
| Structural inspection tied to age | No statewide requirement | Milestone Inspection at 25 or 30 years [3] | |
| Reserve waiver allowed | Governed by declaration/bylaws | No, for SIRS components since Dec 31, 2024 [4] | If you manage or sit on a board for a building with ties to both states, or you're just comparing how much stricter Florida's regime has become, this is the core distinction: Washington leaves more to the association's own declaration and board judgment, Florida has increasingly taken that discretion away for structural safety items. |
Washington requires a reserve study for essentially all condo associations under RCW 64.34.380, updated at least every three years, but it does not mandate a separate structural safety inspection tied to building age, and it does not make specific component reserves legally non-waivable the way Florida's post-Surfside reforms do [1]. Florida's law, enacted after the 2021 Champlain Towers South collapse, requires buildings three stories or more to get a Milestone Inspection at 30 years (25 years within 3 miles of the coast) and separately requires a Structural Integrity Reserve Study (SIRS) covering specific structural components, with the reserve contributions for those SIRS components legally required and no longer waivable by a membership vote, under Florida Statutes Chapter 718 [3][4]. Washington has no equivalent statewide milestone inspection trigger tied to building age or coastal proximity. | Feature | Washington (RCW 64.34) | Florida (Ch. 718) |
What triggers a reserve study update in Washington, and who has to prepare it?
RCW 64.34.380 requires the board to review the reserve study annually and have it fully updated, meaning a new physical inspection and revised funding plan, at least every three years [1]. Annual review doesn't require a brand-new site visit every year; it means the board checks whether cost estimates, inflation assumptions, or completed projects have changed the funding picture enough to warrant action before the three-year mark. The statute doesn't require a specific license for who prepares the study, unlike some states that mandate a licensed engineer for structural components. In practice, most Washington associations hire a reserve study firm, often one with CAI-credentialed staff (RS or PRA designation), and bring in a licensed structural engineer separately only if there's a specific concern like foundation movement or facade deterioration. Boards should also check their own declaration and bylaws, since some Washington condo declarations written before the 2018 shift to RCW 64.90 impose stricter update schedules or specific vendor qualifications than the statutory minimum. When state law and governing documents differ, the more restrictive requirement usually controls, but confirm that with association counsel rather than assuming.
What happens if a Washington condo association skips its reserve study?
There's no direct state fine for failing to get a reserve study under RCW 64.34.380, unlike some states with civil penalty provisions, but the practical consequences show up elsewhere: resale certificates required under RCW 64.34.425 must disclose reserve fund status, and a missing or stale study makes that disclosure incomplete or inaccurate, which can expose the board to liability if a buyer later claims they weren't given accurate financial information before purchase. Lenders are a bigger practical risk. Fannie Mae and many private lenders require condo project review documentation that includes reserve funding information before approving mortgages in the building; a project without adequate reserve documentation can end up on a lender's ineligible list, which makes units harder to sell or refinance across the entire building, more than the seller's unit. The board also carries fiduciary exposure. If a major system fails and there was no reserve study establishing what the association should have been saving, owners suing over resulting special assessments or property damage have an easier argument that the board breached its duty of care by failing to plan. None of this is guaranteed litigation outcome, since every case turns on specific facts and the association's declaration, but it's the practical risk boards are managing when they skip the study to save a few thousand dollars.
How do Burien boards use the reserve study day to day?
The reserve study report itself just sits on a shelf unless the board actually uses it to build the annual budget, communicate with owners, and track progress. Practically, that means three things every year: pulling the current-year funding target from the study into the draft budget, comparing actual reserve contributions against that target, and flagging any component whose estimated remaining life has shifted (a roof lasting longer than projected, or a water heater failing early). Boards that treat the reserve study as a living document, not a one-time report, catch funding gaps early enough to phase in dues increases instead of hitting owners with a surprise special assessment. That's the entire point of the three-year update cycle: it's supposed to catch drift before it becomes a crisis. This is where a lot of volunteer boards struggle, not because the concept is complicated, but because tracking deadlines (three-year update, annual review, resale certificate disclosures, lender documentation requests) across a spreadsheet or email folder gets messy fast, especially with board turnover. If you want a structured way to keep these dates, documents, and owner communications organized without hiring a management company for it, our Building-Specific Board Compliance Kit is a $199 one-time toolkit built for exactly this kind of recurring compliance tracking. It doesn't replace your reserve study provider or your attorney, it just keeps the paperwork and deadlines from falling through the cracks between board terms.
What should Burien boards ask a reserve study provider before hiring them?
Ask for their CAI credential status first (RS or PRA), since Washington's statute doesn't require licensing but credentialed providers follow a documented, peer-reviewed methodology that holds up better if a resale certificate or lender review is later challenged. Ask whether the quote is for a full study (on-site inspection, new component list) or an update study, since those are priced and scoped very differently. Ask for two or three sample reports from comparable buildings (similar unit count, age, systems) before signing, so the board can see how detailed the component list and funding plan actually are; some cheaper providers deliver thin reports that technically satisfy the statute but don't give the board enough detail to plan real projects. Ask what happens between full studies, specifically whether the provider's update pricing is fixed in the initial contract or renegotiated each cycle. Finally, ask how the provider handles components the board is unsure about ownership on, shared plumbing stacks, party walls, and similar gray areas that come up in condo declarations. A good reserve study provider will flag these for the board to confirm with counsel rather than guessing at inclusion or exclusion.
Frequently asked questions
What is a reserve study?
A reserve study is a physical inspection and financial analysis of an association's shared components (roofs, elevators, paving, plumbing) that estimates each item's remaining useful life and replacement cost, then produces a funding plan showing how much the association should save annually. It's the primary budgeting tool boards use to avoid special assessments.
What is a reserve study for an HOA?
For an HOA, a reserve study covers shared common-area assets, clubhouse, pool, private roads, retention ponds, rather than components inside individual homes. The methodology matches a condo reserve study: inventory components, estimate remaining life, and build a multi-year funding schedule so dues cover future replacement costs without a surprise special assessment.
What is an HOA assessment?
An HOA assessment is the regular fee owners pay (monthly or quarterly) covering operating costs and reserve contributions. It's distinct from a special assessment, which is a one-time or limited charge levied outside the regular fee, usually to cover an emergency repair, a reserve shortfall, or a specific capital project.
What are HOA assessments used for?
Regular HOA assessments fund day-to-day operating expenses (landscaping, insurance, management, utilities for common areas) and the reserve fund contribution for future major repairs. Special assessments, a separate category, cover shortfalls or unplanned capital costs, like an urgent roof replacement, that regular dues and reserves didn't fully anticipate.
How much should an HOA have in reserves?
There's no fixed dollar figure; what matters is percent funded, your reserve balance divided by what should be on hand given component depreciation. Industry practice generally treats 70%+ as strong, 30-70% as fair, and under 30% as high risk for special assessments, though no state statute mandates a specific percentage target.
How much does a reserve study cost?
A full reserve study for a mid-size condo (20-100 units) typically runs $3,000 to $8,000, with larger or more complex buildings costing more. Update studies that reuse the existing component inventory usually cost $500 to $2,000 less than a full study since they skip the on-site inspection.
Are HOA special assessments tax deductible?
Generally no, for owner-occupied units, since special assessments for capital improvements or reserves add to your property's cost basis rather than qualifying as a current-year deduction under IRS rules. Rental property owners may be able to depreciate a portion; casualty-related assessments in declared disaster areas have narrow exceptions. Consult a CPA for your specific situation.
Does Washington law require condo associations to get a reserve study?
Yes. RCW 64.34.380 requires most Washington condo associations to have a reserve study, updated at least every three years with annual board review in between, unless a narrow statutory exemption applies. This applies statewide, including Burien, with no local city carve-out.
How is Burien's condo reserve study requirement different from Florida's SIRS?
Washington requires a reserve study under RCW 64.34.380 with no separate age-triggered structural inspection mandate. Florida requires both a Milestone Inspection at 25 or 30 years (Ch. 718) and a Structural Integrity Reserve Study with legally non-waivable reserve funding for specific structural components, a much stricter regime adopted after the 2021 Surfside collapse.
Who is qualified to prepare a reserve study in Washington?
Washington's statute doesn't mandate a specific license for reserve study preparers. Most associations hire firms with staff holding the Community Associations Institute's Reserve Specialist (RS) or Professional Reserve Analyst (PRA) credential, and bring in a licensed structural engineer separately only if there's a specific structural concern.
What happens if a Burien condo association doesn't update its reserve study?
There's no direct state fine, but resale certificates under RCW 64.34.425 must disclose reserve fund status, and a stale study makes that disclosure inaccurate. Lenders reviewing the building for mortgage approval may also flag inadequate reserve documentation, which can put units on an ineligible list and hurt resale and refinancing across the building.
Can a Washington HOA waive its reserve requirement with a membership vote?
It depends on the association's declaration and whether an exemption under RCW 64.34.380 applies; the statute allows some small associations to opt out, but most condos cannot simply vote away the reserve study requirement. Confirm the specific exemption language and your association's eligibility with counsel before assuming a waiver is valid.
