HOA reserve study requirements by state: who must do one, how often, and who may prepare it

What this guide covers

Whether a reserve study is a legal obligation or merely a good idea depends entirely on where the association sits. This guide reads the reserve-study provisions of five states directly and sets them beside one another: California, Nevada, Washington, Virginia and Florida. For each it answers the same three questions a board actually has — is a study compulsory, how often, and who is allowed to prepare it.

It covers those five and no others: they are the ones whose text was pulled from each state’s own legislature site and read for this page. A state’s absence here is not a finding that it leaves reserves alone — it means its text was not read here. Utah, Hawaii and Colorado were attempted and could not be retrieved from a primary government source, so this guide says nothing about them.

One structural point before the detail: in most of these states the homeowners’ association act and the condominium act are separate, with different rules, and an association can sit under either. The answer to “do we need a study” often turns on that question first.

The short answer

• California is the strictest of the five on cadence: the board causes a reasonably competent and diligent visual inspection of the accessible areas of the major components to be conducted at least once every three years, as part of a study of reserve account requirements, where the current replacement value of those components is at least one-half of the association’s gross budget excluding reserves (Civ. Code § 5550(a)).
• A California study identifies the major components with a remaining useful life under 30 years, their probable remaining life, the cost of repair or replacement, the total annual contribution needed, and a reserve funding plan (Civ. Code § 5550(b)).
• Nevada sets a five-year cycle and, unusually, regulates who may do the work: the study is conducted at least once every five years by a person holding a permit under chapter 116A, and a summary goes to the Division no later than 45 days after the board adopts the results (NRS § 116.31152).
• Washington requires an annual update, not just a periodic study: an association prepares and updates a reserve study, with an updated study prepared at least every third year by a reserve study professional based on a visual site inspection (RCW § 64.90.545).
• Virginia runs on the longest cycle of the five and applies the same rule to both community types: the board conducts a study at least once every five years to determine the necessity and amount of reserves, reviews the results at least annually, and adjusts the budget as it deems necessary (Va. Code §§ 55.1-1826, 55.1-1965).
• Florida does not make a reserve study compulsory for homeowners’ associations at all. Reserve accounts may be included in the budget, and the association is deemed to have provided for them only on the affirmative approval of a majority of the total voting interests (Fla. Stat. § 720.303(6)(b), (6)(d)).
• Florida condominiums are the exception to that: a residential condominium association must have a structural integrity reserve study completed at least every 10 years for each building three habitable stories or higher (Fla. Stat. § 718.112(2)(g)1.).

The five statutes side by side

State	What the law says on reserves
California	Visual inspection and study at least once every three years where component replacement value is at least half the gross budget, reviewed annually (Civ. Code § 5550(a))
Nevada	Study at least once every five years by a permit holder under chapter 116A; reviewed at least annually; summary to the Division within 45 days of adoption (NRS § 116.31152)
Washington	Prepared and updated annually, with a professional study based on a visual site inspection at least every third year (RCW § 64.90.545)
Virginia	Study at least once every five years, results reviewed at least annually, budget adjusted as the board deems necessary (Va. Code §§ 55.1-1826, 55.1-1965)
Florida	No study obligation for homeowners’ associations; reserves are elected by a majority of total voting interests (Fla. Stat. § 720.303(6)(d)). Condominium buildings three habitable stories or higher: a structural integrity reserve study at least every 10 years (Fla. Stat. § 718.112(2)(g)1.)

Step by step

1. Settle which act governs you first

The distinction is not academic. In Washington the older homeowners’ association provision and the newer common interest ownership provision coexist, and the homeowners’ association rule is expressly qualified — an association with significant assets prepares and updates a reserve study unless doing so would impose an unreasonable hardship (RCW § 64.38.065(2)). The newer act drops the hardship language and instead lists closed-ended exemptions, including communities restricted to nonresidential use, those with only nominal reserve costs, and the case where the cost of the study or update exceeds 10 percent of the association’s annual budget (RCW § 64.90.545(2)). Two associations on the same street can sit under different rules.

Virginia is the tidiest of the five here: the property owners’ association provision and the condominium provision carry materially the same obligation, each subject to what the governing instruments say (Va. Code §§ 55.1-1826, 55.1-1965).

2. Work out whether the threshold catches you

California’s obligation is conditional, and the condition is a ratio rather than a unit count: the study duty attaches where the current replacement value of the major components the association must repair or replace is equal to or greater than one-half of the gross budget, excluding the reserve account for that period (Civ. Code § 5550(a)). Gas, water and electrical service lines count as major components to the extent the association is responsible for them (Civ. Code § 5550(c)).

Florida’s condominium threshold is physical instead: it is the building’s height, measured as three habitable stories or higher under the Florida Building Code, not the association’s budget or age (Fla. Stat. § 718.112(2)(g)1.).

3. Check who is allowed to sign it

Two of the five states put limits here, and they are the ones to check before commissioning work. Nevada requires a permit holder under chapter 116A, with a narrow carve-out: a community of 20 or fewer units in a county whose population is under 55,000 may use any person the board deems qualified (NRS § 116.31152(2)). Florida requires a structural integrity reserve study to be performed or verified by a licensed engineer, a licensed architect, or a person certified as a reserve specialist or professional reserve analyst, and it forces bidders to disclose in writing any intent to bid on the repair work the study recommends (Fla. Stat. § 718.112(2)(g)3.).

Washington names a “reserve study professional” for the initial study and the triennial update but leaves the decision whether to use one on any given update to the board’s reasonable discretion under the older act (RCW § 64.38.065(2), (4)).

4. Review the results every year, in writing

Every one of the five states that mandates a study also mandates an annual review, and this is the step boards most often skip. California has the board review the study annually and consider and implement necessary adjustments (Civ. Code § 5550(a)). Nevada has the board review the results at least annually to decide whether reserves are sufficient and adjust the funding plan accordingly (NRS § 116.31152(1)). Virginia has the board review the results at least annually and make any budget and assessment adjustments it deems necessary (Va. Code §§ 55.1-1826(B), 55.1-1965(B)).

5. Get the funding plan adopted the right way

California is specific about procedure, and getting it wrong is a real exposure. The reserve funding plan includes a schedule of the date and amount of any change in regular or special assessments needed to fund it, is adopted by the board at an open meeting before the membership, and — where the board determines an increase is necessary — any increase is approved in a separate board action (Civ. Code § 5560).

6. Put the numbers in front of owners

California turns the study into two owner-facing disclosures. A reserve summary based on the most recent study, printed in boldface type, gives each major component’s replacement cost and remaining and useful life, the cash reserves required and actually held, the percentage funded, and the current deficiency expressed per unit (Civ. Code § 5565). The statutory Assessment and Reserve Funding Disclosure Summary then asks the board to answer, in a prescribed form, whether projected reserve balances will be sufficient each year for the next 30 years, and if not, what further assessments would be needed (Civ. Code § 5570(a)).

Florida’s disclosure works in the opposite direction — it discloses the absence of reserves. Where the budget does not provide for statutory reserve accounts and the association is responsible for capital improvements that could trigger a special assessment, each annual financial report carries a warning in conspicuous type telling owners that reserves are not fully funded and that they may elect to fund them (Fla. Stat. § 720.303(6)(c)1.).

7. Understand what a waiver can and cannot do

Florida’s homeowners’ association members may vote to provide no reserves or less than the statute would require, and such a vote applies to one budget year only (Fla. Stat. § 720.303(6)(f)). The condominium side has been narrowed: for a budget adopted on or after December 31, 2024, members of a unit-owner-controlled association that must obtain a structural integrity reserve study may not vote to underfund the items that study covers (Fla. Stat. § 718.112(2)(f)2.b.).

Common mistakes

• Treating the study as a one-off. Four of the five states pair the study with an explicit annual review duty, and the review is a separate obligation from the study itself (Civ. Code § 5550(a), NRS § 116.31152(1), Va. Code § 55.1-1826(B), RCW § 64.90.545(1)).
• Commissioning the cheapest provider. In two of these states an unqualified preparer means the study does not satisfy the statute at all (NRS § 116.31152(2), Fla. Stat. § 718.112(2)(g)3.).
• Missing the filing step. Nevada’s summary goes to the Division no later than 45 days after the board adopts the results, and nothing in the statute makes that contingent on a request (NRS § 116.31152(4)).
• Raising assessments in the same motion that adopts the plan. In California the funding plan and any assessment increase it implies are separate actions (Civ. Code § 5560(b), (c)).
• Assuming a Florida waiver is permanent. A vote to reduce or skip reserves reaches one budget year, and if the meeting fails or falls short of quorum the budgeted reserves take effect (Fla. Stat. § 720.303(6)(f)).

Where software fits

The study itself is an engineering and accounting product, not something a portal generates. What a platform can carry is the paperwork around it: the annual review, the funding plan and the owner-facing summaries. Platforms for association accounting and document delivery are compared in our best-of roundups; this page stays with what the law says.

When to involve counsel

Bring counsel in before leaning on a hardship or exemption argument to skip a study, before a waiver vote, and before adopting a funding plan that leaves a known deficiency unfunded — in several of these states the board’s own annual review is the record that gets read back to it later. Counsel is also the right call when an association’s governing documents impose more than the statute does, which Washington expressly permits them to do (RCW § 64.90.545(3)).
