Washington Reserve Study Requirements (2026): RCW 64.34 & 64.38 today, WUCIOA by 2028.

Washington is mid-transition. Most associations still follow the older Condominium Act or HOA Act, while newer communities already live under WUCIOA — and a 2028 cutover will bring nearly everyone under the same modern statute. Here's what that means for your reserve study, and what to do now.

1. Why Washington has three statutes at once

Washington's common-interest law grew in layers, which is why three chapters of the RCW are all live right now:

• RCW 64.34 — the Washington Condominium Act (1989). Governs condominiums created from 1990 through mid-2018.
• RCW 64.38 — the Homeowners' Associations Act. Governs many pre-2018 HOAs (plats and planned communities).
• RCW 64.90 — WUCIOA (the Washington Uniform Common Interest Ownership Act). The modern, unified act effective July 1, 2018, covering condos, HOAs, and co-ops created on or after that date.

So today, which rules apply to your association depends mostly on when it was created. That's the part about to change.

2. What's required today

Under both the older acts and WUCIOA, the reserve-study expectation is consistent in spirit: prepare a reserve study, fund toward it, and keep it current. The Washington wording is distinctive, though — the statutes say an association "should" do these things, and back that up with a liability safe harbor rather than a hard penalty.

• Prepare a reserve study covering the components the association is responsible to repair and replace.
• Update it annually, with a full update that includes an on-site inspection at least every three years.
• Disclose reserve information to owners (funding status and the basis for it).

The safe-harbor structure is the key to understanding Washington. A board that follows the reserve-study process gains protection from certain owner claims about reserve adequacy. A board that ignores it doesn't just risk underfunding — it forfeits that statutory protection and takes on more personal exposure. In practice, "should" functions a lot like "had better."

3. What WUCIOA changes

WUCIOA (RCW 64.90) modernizes and tightens the reserve framework. For reserves, the themes are:

• A clearer reserve-study and reserve-account expectation for the association's responsibility components.
• Stronger funding and disclosure language, so owners and buyers can see the reserve position more readily.
• Consistency across community types — one statute for condos, HOAs, and co-ops instead of three overlapping ones.

If your community was created on or after July 1, 2018, this is already your world. If not, it's where you're headed.

4. The 2028 transition, in plain terms

The headline for most Washington boards is consolidation. Washington has moved to bring the remaining pre-2018 associations under WUCIOA, with a January 1, 2028 cutover. After that date, the older RCW 64.34 and 64.38 reserve provisions give way to WUCIOA for those communities.

The practical takeaway: by 2028, "which statute applies?" stops being a question. Nearly every Washington common-interest community should expect to run its reserves under WUCIOA.

5. What Washington boards should do now

1. Confirm which act governs you today. It hinges on your community's creation date relative to July 1, 2018.
2. Keep your reserve study current. Annual updates with a full, site-visit update every three years is the standard either way — and it preserves your safe-harbor protection.
3. Tighten funding and disclosure now. WUCIOA's direction is toward stronger funding and clearer owner disclosure, so moving that way early avoids a scramble in 2027.
4. Calendar the 2028 cutover. Put a governing-documents and reserve-policy review on the board agenda well before January 1, 2028.
5. Confirm specifics with Washington counsel. The transition has real nuance; a community-association attorney can confirm exactly how it applies to your association's documents.

6. Bottom line

Washington is consolidating decades of overlapping condo and HOA law into one modern statute. Today your reserve-study obligations depend on when your community was created; by January 1, 2028, almost all of them run under WUCIOA. The good news is that the right habit doesn't change with the statute: keep a current reserve study, fund toward it, disclose it clearly — and you'll be compliant before and after the cutover.
