TLDR
Washington requires professional reserve studies every three years under RCW 64.34.380 (condos) and RCW 64.90.545 (WUCIOA common interest communities). Both HOAs and condos are covered. No funding mandate exists and no post-Surfside changes have been enacted.
Washington’s adoption of the Uniform Common Interest Ownership Act in 2018 brought the state’s reserve requirements in line with other UCIOA states. For boards of newer communities in the Seattle metro area, Bellevue, or the Eastside, the reserve study requirement is clear. For older communities, the answer depends on the governing documents, which is why a quick review of the CC&Rs is the first step before assuming no obligation exists.
Boards often treat reserve studies as a one-time project. Washington’s annual review requirement means the work does not end after the first study. The annual review can be informal: compare the study’s assumptions to current conditions, check whether any components have deteriorated faster than projected, and confirm the funding contributions are on track. If the answer to all three is yes, document that in the minutes and move on. If not, the board needs to adjust the plan.
Professional Reserve Study Every Three Years
RCW 64.34.380 (condos) and RCW 64.90.545 (common interest communities under WUCIOA) require professional reserve studies every three years. The study must identify major components, estimate remaining useful life, and calculate the funding needed. This three-year cycle is among the most frequent study mandates in the country.
Both HOAs and Condos Covered
Washington covers both condominiums under the Condominium Act (RCW 64.34) and common interest communities under WUCIOA (RCW 64.90). This means planned community HOAs formed under WUCIOA are also subject to the three-year reserve study cycle, not just condos.
No Funding Mandate
Washington requires the reserve study but does not mandate a specific funding level or percent-funded threshold. Boards have discretion over the funding plan, but the three-year study cycle creates a regular documented checkpoint. Boards that repeatedly ignore study recommendations face stronger fiduciary exposure.
Which Older Associations Are Covered
WUCIOA (RCW 64.90) governs common-interest communities created on or after July 1, 2018. Older associations may be governed by RCW 64.38 (HOAs) or the Horizontal Property Regimes Act. RCW 64.34.380 covers condominiums regardless of creation date. Boards of older planned communities should review their governing documents.
Governing Documents May Impose Stricter Requirements
Many Washington HOA declarations and bylaws require reserve studies and reserve funding regardless of which statute governs. A board cannot rely on a statutory gap to avoid reserve obligations if the governing documents require them. The CC&Rs control when they are stricter than the statute.
Fannie Mae Reserve Allocation Requirement
Fannie Mae Lender Letter LL-2026-03 sets two deadlines: (1) The Limited Review process for condo projects is retired effective August 3, 2026. (2) The minimum reserve allocation increases from 10% to 15% for Full Review loan applications dated on or after January 4, 2027. Associations below the 15% threshold will be classified as non-warrantable, preventing conventional mortgage lending on units in the community.
Compliance Protects Against Member Claims
A board that conducts regular reserve studies and funds them according to the study's recommendations has a documented basis for its reserve decisions. Washington courts look at whether the board exercised reasonable business judgment. A current study and a funded reserve account are evidence of that judgment.
