Updated September 4, 2026. Quick answer: Washington ratifies special assessments the same way Vermont does, by owner non-rejection, but it’s the only one of these five states whose statute lets the board set up installment payments for a special assessment.
Key statute: Wash. Rev. Code § 64.90.525 (budget ratification and special assessments); § 64.90.502 (emergency assessments); § 64.90.485 (liens, interest, late charges, notice of delinquency); § 64.90.545 (reserve studies) – Washington Uniform Common Interest Ownership Act
How Washington lets an association approve it
Washington’s process is structurally the same as Vermont’s ratification-by-non-rejection model, plus a separate emergency path. Under RCW 64.90.525, “The board must provide a copy of the budget to all unit owners and set a date for a meeting…not less than fourteen nor more than fifty days after providing the budget,” and “Unless at that meeting the unit owners of units to which a majority of the votes…are allocated reject the budget, the budget and the assessments…are ratified.” A special assessment follows the same track: “The board, at any time, may propose a special assessment…effective only if the board follows the procedures for ratification of a budget…and the unit owners do not reject the proposed assessment.” Separately, RCW 64.90.502(6) allows the board alone to act in a declared emergency if “the board determines by a two-thirds vote that a special assessment is necessary,” effective immediately.
The notice you’re owed
For a standard special assessment, the ratification meeting must be set “not less than fourteen nor more than fifty days after providing the budget,” per RCW 64.90.525. In an emergency, RCW 64.90.502(8) only requires that “the board shall promptly notify the unit owners of the action in a manner that is practicable and appropriate under the circumstances,” with no fixed day count.
Paying it: plan, interest, and late fees
Washington stands out here: its statute gives owners a real, explicit right to pay a special assessment in installments, not just silence left to the bylaws. RCW 64.90.525 states, “The board may provide that the special assessment may be due and payable in installments over any period it determines and may provide a discount for early payment.” That installment option is set by the board rather than something an individual owner can demand on their own, but the statute is the source of the right, which is unusual among these states. On interest, RCW 64.90.485 lets the association “establish reasonable late charges and a rate of interest to be charged…not to exceed the maximum rate calculated under RCW 19.52.020, on all subsequent delinquent assessments”; if the association sets no rate, delinquent assessments default to interest “from the date of delinquency at the maximum rate calculated under RCW 19.52.020.”
Washington gives the association a statutory lien on each unit for unpaid assessments, enforceable through judicial foreclosure, but foreclosure can’t start until a unit is at least three months or $2,000 behind, whichever is greater, and pre-foreclosure notice requirements have to be met first.
Does Washington require a reserve study?
Yes, and Washington’s reserve-study law is stricter and more frequent than Virginia’s, not the same rule under a different name. RCW 64.90.545 requires an initial reserve study “prepared by a reserve study professional and based upon either a visual site inspection of completed improvements or a review of plans and specifications.” After that, “An updated reserve study must be prepared annually. An updated reserve study must be prepared at least every third year by a reserve study professional and based upon a visual site inspection.” There are exemptions, including nonresidential-only communities, communities with nominal reserve costs, certain middle-housing communities without on-site wastewater systems, and cases where the study would cost more than 10% of the annual budget, unless the governing documents require it anyway.
Honest gaps
The exact subsection numbering for the notice-of-delinquency requirement in RCW 64.90.485, and the claim that RCW 64.90.545 applies to essentially all common interest communities starting January 1, 2026 regardless of when they were formed, were confirmed with the help of secondary sources alongside the primary statute rather than fully re-verified word for word in a single pass, so treat the exact effective date and scope as substantially but not completely confirmed.
