Des Moines WA condo reserve study: what boards must know

Last updated 2026-08-14

What is a reserve study?

A reserve study is a physical inspection and financial forecast, usually done by an engineer or a reserve study specialist, that answers two questions for a condo or HOA: what major common-element components exist and how long will they last, and how much money does the association need to set aside each year so it can pay for replacements without hitting owners with a surprise bill. A typical study has two parts. The physical analysis lists every major component the association is responsible for (roof, siding, parking lot, elevators, pool, seawall if you're near the water) along with its estimated remaining useful life and replacement cost. The financial analysis takes that list and models a funding plan, usually a 20 to 30 year projection, showing what the reserve account balance should look like year by year under a chosen funding strategy ^[1]. In Washington, reserve studies for condos are governed by RCW 64.34.380, part of the Washington Condominium Act. That statute says an association's board "shall cause a reserve study to be conducted no less frequently than every three years" unless the declaration or bylaws call for something more frequent, and it lays out what the study has to contain, including a component list, useful life estimates, and a funding plan ^[2]. For HOAs governed by the Washington Homeowners' Association Act (RCW 64.38), a nearly identical reserve study requirement applies under RCW 64.38.070, though single-family detached HOAs with no shared building components are often exempt in practice because there's little to study ^[3].

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

The mechanics are the same, but the trigger is different. For a condominium in Des Moines, WA, the association owns and is responsible for the building shell, roof, siding, and common structural elements, so the reserve study has to cover all of that. For a planned-unit HOA where owners individually own their homes and the association only maintains shared amenities (a clubhouse, private roads, a pool, retention ponds), the reserve study only needs to cover what the association is actually responsible for under its governing documents. RCW 64.38.070 requires HOAs with significant common-element responsibilities to prepare and update a reserve study, and it requires the board to review the study annually and update it at least every three years, same cadence as the condo statute ^[3]. If your HOA's declaration says the association only maintains a small entry sign and some landscaping, a full engineering-grade reserve study may be overkill; a simple internal component list can sometimes suffice. Confirm with your association's counsel whether your specific governing documents trigger the full statutory requirement, because the line between 'minimal common elements' and 'significant common elements' isn't always obvious from the statute text alone.

How much does a reserve study cost?

For a mid-size Des Moines, WA condo association (say, 20 to 60 units), a full reserve study with a site visit typically costs somewhere between $3,000 and $8,000, depending on the number of components, whether the building has elevators or a pool, and whether the firm does an on-site visual inspection versus a desktop update using prior data. Larger or more complex buildings, especially anything with structural or waterfront elements common along Puget Sound, can run higher. An update-only reserve study (no new site visit, just refreshing the numbers based on inflation, reserve fund growth, and component aging) usually costs less than a full study, often in the $500 to $2,000 range, and many associations alternate: a full study every 5 to 6 years with with-site-visit updates in between, or an update every year the statute doesn't require a full refresh. There's no statewide fee schedule for reserve study providers in Washington; costs are set by the market, so get at least two or three quotes from firms that specifically do Pacific Northwest condo and HOA work, since coastal moisture and seismic considerations differ from what a national firm might default to. Compare that cost against the alternative: a special assessment for an unbudgeted roof replacement on a 40-unit building can easily run $10,000 to $30,000+ per unit. A reserve study that costs $5,000 total, split across the whole association, is cheap insurance against that outcome.

What is an HOA assessment?

An assessment is the recurring or one-time payment an owner is legally required to pay to the association to cover shared expenses. Regular assessments (sometimes called dues) cover ongoing costs: landscaping, insurance, management fees, utilities for common areas, and contributions to the reserve fund. These are typically billed monthly or quarterly and are set by the board's annual budget. A special assessment is a separate, usually one-time charge levied when the regular assessments and existing reserves aren't enough to cover a specific cost, most often a major repair or replacement that either wasn't anticipated or wasn't fully funded in reserves. If your Des Moines, WA building suddenly needs a $200,000 roof and the reserve account only has $60,000 saved, the board typically has to levy a special assessment to cover the shortfall, spread across all owners according to the formula in the declaration (usually by unit percentage or square footage). Washington's condo statute, RCW 64.34.360, governs how assessments are levied and collected, including lien rights the association has if an owner doesn't pay ^[4]. For HOAs, the parallel provision is in RCW 64.38.020, which lists the board's powers, including the power to levy and collect assessments ^[5].

How much should an HOA have in reserves?

There's no single dollar figure or percentage that's 'right' for every association; it depends on the age, size, and condition of the buildings and infrastructure. The honest answer is that your reserve study should tell you the target, not a rule of thumb, because a 1970s building with an aging roof needs a very different reserve balance than a 2015 building with 25 years of useful life left on most major components. That said, reserve study professionals commonly reference a metric called "percent funded": the ratio of what the association actually has saved versus what it theoretically should have saved at this point in each component's life cycle, given full straight-line funding. Community associations institute research and industry guidance generally treat 70% funded or higher as "good" and under 30% funded as "weak" or at high special-assessment risk, though these thresholds come from industry practice rather than any Washington statute ^[1]. A cash-flow (or 'pooled') funding plan, which spreads contributions across all components rather than saving separately for each one, is the approach most reserve study firms recommend today because it smooths out the funding curve and avoids sudden jumps in required contributions. Ask your reserve study provider to show you the percent-funded trajectory over the next 10, 20, and 30 years under your current contribution rate, more than next year's number.

How often does Washington require reserve study updates?

At least every three years for both condos (RCW 64.34.380) and HOAs with significant common elements (RCW 64.38.070) ^{[2] [3]}. The statute's exact language for condos: the board "shall cause a reserve study... to be conducted no less frequently than once every three years" ^[2]. Some declarations require annual updates, in which case the stricter document requirement controls. Between full studies, the board is expected to review and, where needed, adjust the reserve funding plan annually as part of the regular budget process. A full study every 3 years with internal review in between is the practical minimum; associations with aging buildings, coastal exposure, or components nearing end of life often benefit from updating every 1 to 2 years so the funding plan doesn't get stale.

Are HOA special assessments tax deductible?

Generally, no, not for a typical owner-occupied unit. Special assessments used for capital improvements or major repairs to the building are treated by the IRS similarly to a capital expenditure. For a personal residence, that usually means the assessment isn't deductible in the year paid, but it may increase your cost basis in the property, which can reduce capital gains tax when you sell ^[6]. There are exceptions. If the unit is a rental property, a special assessment for repairs may be deductible as a business expense in the year paid, or depreciated over time if it's a capital improvement, following the same rules that apply to any other landlord expense. If the assessment is for casualty-loss repair tied to a federally declared disaster, different rules can apply. This isn't specific tax advice, IRS treatment depends on your personal situation and the nature of the underlying repair, so talk to a CPA before assuming either way. IRS Publication 523 and Publication 527 cover the basis and rental-expense rules that generally apply here ^{[6] [7]}.

What happens if a Washington association doesn't do a reserve study?

Washington's statutes require the study; they don't spell out a specific state fine or penalty for skipping it the way Florida's SIRS statute does with its escrow and lien consequences. But skipping the reserve study doesn't make the underlying problem (aging roof, failing siding, deferred maintenance) go away, it just means the board finds out about it later, usually at the worst possible moment, and has to solve it with a special assessment instead of a funding plan. There's also liability exposure. Board members owe a fiduciary duty to the association, and failing to follow a statutory requirement like RCW 64.34.380 can become relevant if owners later sue over a special assessment they say could have been avoided with proper planning. Getting the study done, keeping records of when it was last updated, and documenting the board's funding decisions each year is cheap protection against that kind of claim. If your building is near the water in Des Moines, WA or elsewhere on Puget Sound, moisture intrusion and wood rot issues tend to show up earlier and cost more to fix than reserve studies modeled on inland, drier-climate assumptions predict. A reserve study firm with real Pacific Northwest experience will price those risks in more realistically.

How is a Washington reserve study different from Florida's SIRS requirement?

They're solving the same basic problem, but Florida's approach is much more prescriptive following the Surfside collapse. Florida condo associations over 3 stories now face a Structural Integrity Reserve Study (SIRS) requirement under Florida Statutes 718.112 and 553.899, with a mandatory reserve study cycle tied to milestone inspections, plus a rule that boards generally can't waive or reduce reserves for the specific structural components the SIRS covers ^[8]. Washington has no equivalent 'SIRS' or milestone inspection statute. The reserve study requirement under RCW 64.34.380 is a general funding-planning tool, not tied to a specific building height or age trigger, and Washington law doesn't currently mandate the same non-waivable structural reserve funding that Florida imposes post-Surfside. That doesn't mean Washington buildings are risk-free, it means the statutory floor is lower and boards have more discretion (and more responsibility) to decide how much structural risk they're comfortable carrying underfunded. For readers who split time between Washington and Florida properties, or who serve on boards in both states, it's worth understanding how differently the two states treat this. Florida's reserve fund relief provisions and its reserve study framework are far more rigid than anything in the Washington condo act.

What should a Des Moines, WA board actually do with the reserve study once it's done?

Use it to set next year's budget, more than file it away. The reserve study gives you a recommended annual contribution; the board then has to decide, as part of the normal budget process, whether to fund at that level, below it (accepting more special-assessment risk later), or above it (building a cushion faster). Share the key numbers with owners. Percent funded, the recommended contribution, and the projected reserve balance over the next 10 years are the numbers owners actually care about when they're deciding whether to support a special assessment or a dues increase. Boards that hide this information tend to get blindsided by owner pushback when a special assessment finally does become necessary. Keep the paper trail. Meeting minutes showing the board reviewed the study, discussed funding options, and made a documented decision are your best protection if an owner later challenges a special assessment or claims the board was negligent. A hoa reserve study review should happen on the agenda every year the study isn't fully refreshed, more than the years a new engineer walks the property. For boards juggling a reserve study alongside insurance renewals, budget season, and owner communication, a structured system for tracking deadlines and generating owner notices saves real time. That's the gap a $199 one-time Building-Specific Board Compliance Kit is built to fill (see /board-kit-builder); it organizes your reserve study cycle, budget calendar, and required owner notices in one place. It doesn't replace your reserve study specialist or your attorney, it just keeps the paperwork from falling through the cracks between their reports.

What if the reserve study finds the association is badly underfunded?

First, don't panic and don't ignore it, either reaction makes the eventual fix more expensive. A reserve study that comes back at 15% funded with a roof needing replacement in 4 years is telling you exactly what's coming; the only real choices are raise contributions now, plan a special assessment, take out a reserve or renovation loan, or some combination of the three. Many associations phase in a funding correction over 3 to 5 years rather than jumping to full recommended funding in one year, which softens the budget shock for owners on fixed incomes. Get the board's attorney to review any assessment increase or special assessment plan against the declaration's notice and voting requirements before you announce it; procedural mistakes (wrong notice period, wrong vote threshold) are one of the most common ways a special assessment gets challenged and delayed. If a special assessment is coming, look at condo special assessment insurance options and communicate early and often. Owners who get 60 to 90 days of advance notice and a clear explanation of why the assessment is necessary are far less likely to fight it than owners who get a surprise bill with no context.

Frequently asked questions

What is a reserve study?

A reserve study is a professional inspection and financial analysis that lists an association's major common-element components, estimates their remaining useful life and replacement cost, and recommends an annual funding plan so the association can pay for future repairs without a surprise special assessment.

What is a reserve study for an HOA?

It's the same tool used by condos, applied to whatever shared elements the HOA is responsible for under its governing documents, such as a clubhouse, private roads, or retention ponds. If the HOA only owns minor common areas, the study can be simpler than a full condo building study.

What is an HOA assessment?

An assessment is a payment owners are required to make to the association. Regular assessments cover ongoing operating costs and reserve contributions; special assessments are one-time charges levied when reserves and regular dues aren't enough to cover a major, often unexpected, repair or replacement.

How much should an HOA have in reserves?

There's no universal dollar figure; it depends on your specific components and their age. Industry guidance commonly treats 70% or higher 'percent funded' (actual reserves versus the theoretical ideal for your components' age) as healthy, and under 30% as high risk for a special assessment.

How much does a reserve study cost in Washington?

A full reserve study with a site visit for a mid-size condo typically runs $3,000 to $8,000, depending on building complexity. Update-only studies without a new site visit are usually cheaper, often $500 to $2,000, and many associations alternate full studies with cheaper updates in between.

Are HOA special assessments tax deductible?

Usually not for an owner-occupied unit; a special assessment for a capital repair typically isn't deductible in the year paid but may add to your cost basis, reducing capital gains tax when you sell. Rental property owners may be able to deduct or depreciate the cost as a business expense. Confirm with a CPA.

Does Washington law require condo reserve studies?

Yes. RCW 64.34.380 requires condo association boards to cause a reserve study to be conducted no less frequently than every three years, and it specifies what the study must include: a component list, useful life estimates, and a funding plan.

Does Washington require HOA reserve studies too?

Yes, for HOAs with significant common-element responsibilities, under RCW 64.38.070, on the same three-year update cycle as condos. HOAs with minimal shared infrastructure, like a simple entry sign, may not trigger the full requirement; check with counsel on your specific declaration.

Is a Washington reserve study the same as Florida's SIRS?

No. Florida's Structural Integrity Reserve Study (SIRS), created after the Surfside collapse, applies to condos over 3 stories and includes mandatory, largely non-waivable reserve funding for specific structural components. Washington's reserve study statute is more general and doesn't carry the same structural-component funding mandate.

What happens if a Washington board skips the required reserve study?

There's no specific statutory fine spelled out in RCW 64.34.380, but skipping it doesn't remove the underlying maintenance risk, and it can expose board members to fiduciary-duty claims if an avoidable special assessment later hits owners. Doing the study and documenting funding decisions is cheap protection.

How often should a reserve study be updated?

At least every three years under Washington law for both condos and qualifying HOAs. Many associations do a full study every 5 to 6 years with cheaper update-only reviews in between, and the board should review funding annually as part of its budget process regardless of the statutory minimum.

What's the difference between a full reserve study and an update?

A full study includes a new on-site physical inspection of components and typically costs $3,000 to $8,000. An update-only study reuses the prior inspection data, adjusts for inflation and aging, and usually costs $500 to $2,000, though it can miss new deterioration a site visit would catch.
