01The 30-second summary
WUCIOA (the Washington Uniform Common Interest Ownership Act, RCW Chapter 64.90) is Washington's modernized HOA law. It replaces and consolidates several older statutes — the Horizontal Property Regimes Act (condos pre-1990), the Condominium Act (condos 1990+), and the Homeowners' Association Act (RCW 64.38) — into a single, comprehensive framework.
Why does WUCIOA exist?
Washington's HOA laws were fragmented across multiple statutes depending on when and how a community was created. A 1985 condo operated under different rules than a 2005 planned community. WUCIOA creates a unified set of standards. It applies automatically to all communities created after July 1, 2018, and older communities can opt in. Some provisions apply to ALL communities regardless of when they were created.

02Why should homeowners care?
You might never read the full text of WUCIOA — and you don't need to. But there are specific moments when knowing your rights under Washington HOA law makes a real difference. Here are the most common:
- Your community was built after 2018 and operates under WUCIOA automatically
- Your older community is considering opting into WUCIOA
- You want to request HOA records and need to know the timeline
- The board is raising assessments and you want to understand limits
- You're buying a home and the resale certificate references WUCIOA
- You want to install solar panels or an EV charger
In each of these situations, WUCIOA and Washington HOA regulations define your rights and the HOA's obligations. Knowing the basics of RCW 64.90 means you can ask the right questions before a situation escalates.
03Why should board members care?
If your community was created after July 2018, WUCIOA is your governing statute. If your community is older, some WUCIOA provisions apply anyway, and more will apply if you opt in.
The most common situations where Washington HOA law applies to board operations:
- Meeting notice requirements — open meetings with proper advance notice
- Records production timelines — 10 business days to respond under WUCIOA
- Reserve study obligations — mandatory for WUCIOA communities
- Resale certificate accuracy — detailed financial disclosures to buyers
- Transition from developer control — specific turnover procedures
- Assessment lien procedures — statutory requirements before recording a lien
The biggest challenge for Washington boards: figuring out which rules apply to YOUR community. WUCIOA, the old Homeowners' Association Act (RCW 64.38), and the Condominium Act can all be in play depending on when your community was created and whether you've opted in.

04Common questions
Some WUCIOA provisions apply to ALL Washington HOAs regardless of when they were created — including certain consumer protection rules and resale disclosure requirements. Many boards of older communities assume WUCIOA doesn't affect them, but they may already be subject to key provisions without realizing it.
Does WUCIOA apply to my HOA?
If your community was created after July 1, 2018, yes — WUCIOA applies automatically. If your community is older, some provisions apply to all communities, and your association can opt in to the full Act by amending the declaration with the required member vote. The opt-in is permanent — you can't opt back out.
Relevant law: RCW 64.90.010
Can my HOA opt into WUCIOA?
Yes. Older communities can adopt WUCIOA by amending their declaration. This requires the approval threshold specified in your existing governing documents (typically 67% of members). Opting in brings the full Act into effect for your community, including reserve study requirements and updated governance rules.
Relevant law: RCW 64.90.095
What records can I request under WUCIOA?
Members have broad inspection rights. The association must produce records within 10 business days of a written request. Records include financial statements, meeting minutes, contracts, governing documents, and correspondence. The association can charge reasonable copying costs but cannot deny access to required records.
Relevant law: RCW 64.90.495
Does my HOA need a reserve study under WUCIOA?
If your community was created under WUCIOA (after July 2018), yes. For older communities operating under RCW 64.38, reserve studies are strongly recommended but not strictly mandated (though lender and buyer expectations effectively make them necessary). If your older community opts into WUCIOA, the reserve study requirement kicks in.
Relevant law: RCW 64.90.545
What are the solar and EV protections in Washington?
Washington law (RCW 64.38.055) prohibits HOAs from unreasonably restricting solar panel installations. EV charging protections have been expanding. These provisions apply to all communities, not just those under WUCIOA. Restrictions that significantly increase cost or decrease efficiency are generally not enforceable.
Relevant law: RCW 64.38.055
05Real-world scenarios
The opt-in decision
A 1995 planned community of 85 townhomes has been operating under RCW 64.38. The board proposes opting into WUCIOA to access the updated governance framework and clarify ambiguities in their aging CC&Rs. At the member meeting, homeowners ask what changes. The board explains: clearer meeting procedures, mandatory reserve study, updated resale certificates, and more detailed financial disclosure requirements. The members vote 72% in favor (exceeding the 67% threshold). The community amends its declaration and operates under WUCIOA going forward.
What the board did right: explained the practical impact before the vote and ensured the approval exceeded the required threshold.
What homeowners should consider: the opt-in is permanent and brings additional obligations (like reserve studies) — which is good governance but also means more work and potentially higher dues.
The resale certificate surprise
A buyer purchasing a unit in a WUCIOA community requests the resale certificate. The certificate reveals the association is only 25% funded on reserves and has a pending special assessment of $3,500 per unit for parking lot resurfacing. The buyer negotiates a $3,500 credit from the seller to cover the assessment. Without the WUCIOA-mandated resale certificate, the buyer might not have discovered the pending assessment until after closing.
What the buyer did right: requested and reviewed the resale certificate before closing.
What the disclosure system did right: WUCIOA's resale certificate requirements ensured the buyer had material financial information before committing.

- Resale certificates must disclose material financial information before closing
- Solar panels and EV chargers are broadly protected under Washington law
- Some WUCIOA provisions apply to ALL communities regardless of creation date
- The opt-in to WUCIOA is permanent — your community cannot opt back out
07What board members should remember
- Determine which statute governs your community — RCW 64.38, RCW 64.90, or both
- Provide proper meeting notice — at least 14 days for member meetings
- Respond to records requests within 10 business days under WUCIOA
- Conduct and update reserve studies as required under RCW 64.90.545
- Issue accurate resale certificates with current financial disclosures
- Follow statutory procedures before recording any assessment lien

FAQFrequently asked questions
What is WUCIOA?+
WUCIOA (the Washington Uniform Common Interest Ownership Act, RCW Chapter 64.90) is Washington’s modernized HOA law. It consolidates and replaces several older statutes into a single comprehensive framework governing condominiums, planned communities, and cooperatives created after July 1, 2018.
Does WUCIOA apply to all Washington HOAs?+
Not automatically. WUCIOA applies by default to communities created on or after July 1, 2018. Older communities can opt in by amending their declaration with the required member vote. However, some WUCIOA provisions — including certain consumer protections and meeting requirements — apply to all communities regardless of creation date.
Can my HOA opt into WUCIOA?+
Yes. Older communities can adopt WUCIOA by amending their declaration, typically requiring 67% member approval (or the threshold specified in your governing documents). The opt-in is permanent — once adopted, the community cannot revert to the prior statute.
What is a resale certificate under WUCIOA?+
A resale certificate is a mandatory disclosure document provided to buyers before closing. Under RCW 64.90.610, it must include the association’s financial condition, reserve funding status, pending special assessments, insurance coverage, and other material information. It protects buyers from hidden financial obligations.
Are reserve studies required under WUCIOA?+
Yes, for communities created under WUCIOA (after July 2018) or older communities that have opted in. Under RCW 64.90.545, reserve studies must be updated at least annually, with a full visual-site-inspection update by a qualified professional every three years. For older communities under RCW 64.38, reserve studies are recommended but not mandated until the 2028 transition.
What happens in 2028 for Washington HOAs?+
Under ESSB 5796 (2024), RCW Chapter 64.38 is repealed on January 1, 2028. All Washington HOAs will be governed exclusively by WUCIOA from that date. This means older communities that have not yet opted in will automatically transition to the full WUCIOA framework, including reserve study requirements and enhanced disclosure obligations.
