WUCIOA Insurance Requirements for Washington HOAs (2026)

The WUCIOA insurance requirements come from a single statute, RCW 64.90.470: property, liability, and fidelity coverage for a Washington community association. Whether that mandate binds your community depends entirely on one date. Anything formed on or after July 1, 2018 follows it today, while older communities stay off the insurance section until January 1, 2028.

Washington's Uniform Common Interest Ownership Act, or WUCIOA, took effect July 1, 2018 and governs every newly formed association. Older communities live under different rules. For the market picture, see Washington HOA and condo insurance; from here, this guide sorts out which rules bind which community.

What WUCIOA insurance requirements cover

The WUCIOA insurance requirements sort into four buckets under RCW 64.90.470. A Washington community association carries all four, but only where the coverage is reasonably available. The list below covers each.

1. Property insurance on the common elements, against the physical damage a standard policy covers. The floor is 80% of actual cash value, meaning what the property is worth today after depreciation, not what it would cost to rebuild. Land, excavation, and foundations sit outside that figure.
2. Commercial general liability insurance, including medical payments, set by the board but never below the declaration's figure. It responds when someone is hurt, or property is damaged, in the shared areas.
3. Fidelity insurance, which pays the association back if someone handling its money steals or misuses it. The statute makes it mandatory but names no dollar amount.
4. Any other coverage the declaration requires.

Owner upgrades and the master policy

In a building where units share walls or floors, the master policy has to cover the units themselves, plus any owner upgrades, unless the declaration says otherwise (RCW 64.90.470(2)). Say an owner installs quartz counters and the declaration stays silent. The association's policy picks them up. The older Condominium Act ran the other way, letting the master policy "may, but need not" reach those improvements.

Who pays the deductible

RCW 64.90.470(9) is blunt: "The cost of repair or replacement not paid from insurance proceeds is a common expense." The deductible, the slice of a loss the association pays before insurance kicks in, therefore lands on the association by default. It comes out of reserves or assessments, not the owner nearest the damage.

Governing documents can change that. A board resolution or declaration language can push the deductible onto the owner responsible for a loss, and many newer declarations do. Absent that language, the bill stays put.

Required policy provisions

RCW 64.90.470(4) forces four provisions into every association policy:

• Each owner is an insured for liability tied to the common areas.
• The insurer waives subrogation, so after paying a claim it will not sue an owner or their household to recover the money.
• One owner's mistake cannot void the coverage for everyone else.
• The association's policy pays first where it overlaps an owner's own policy.

Does WUCIOA apply to pre-2018 HOAs?

For insurance, the answer is no, at least for now. RCW 64.90.365 lists the WUCIOA sections that already reach communities formed before July 1, 2018, and the insurance section is not among them. A pre-2018 board still follows its legacy act and its declaration.

The sections that do reach older communities cover annual meetings (RCW 64.90.445), reserve studies (64.90.545), EV charging (64.90.513), and budgets (64.90.525), not insurance. The 2025 amendments under SB 5129 reshuffled that list and still left RCW 64.90.470 off it, so a pre-2018 community keeps following its legacy statute until January 1, 2028.

Which act governs your association

A community's formation date decides which act, and which insurance rules, apply. The table below lines up the four buckets by formation window.

What changes on January 1, 2028

On January 1, 2028, WUCIOA becomes the governing statute for every Washington common-interest community. SB 5796 (2024) repeals the three legacy statutes, RCW 64.32, 64.34, and 64.38, on that date. Afterward, every Washington common-interest community follows RCW 64.90.470, whenever it formed.

The size of the jump depends on where a community starts:

• Pre-1990 condos (RCW 64.32): They move from a near-empty statutory mandate to the full WUCIOA slate, and fidelity insurance becomes mandatory for the first time.
• 1990 to 2018 condos (RCW 64.34): They already carry property and liability, so they mainly add mandatory fidelity coverage and the all-in default on owner upgrades.
• Pre-2018 HOAs (RCW 64.38): These face the widest gap, moving from zero statutory requirements to mandatory property, liability, and fidelity all at once.

Any association whose governing documents do not match WUCIOA by that date is out of compliance the moment the clock turns. Before 2028, compare the declaration and current policies against RCW 64.90.470, then address any missing fidelity or unit-upgrade coverage.

Earthquake: not required, but Cascadia is real

WUCIOA does not require earthquake insurance. The statute reaches "risks of direct physical loss commonly insured against," and earthquakes fall outside a standard property policy, so the mandate skips them too. Many Washington condo associations carry no earthquake coverage, even though the Cascadia subduction zone poses a recognized long-term risk.

The United States Geological Survey estimates the odds of a full or nearly full margin magnitude 9 Cascadia Subduction Zone rupture at roughly 7 to 12 percent over the next 50 years (USGS Professional Paper 1661-F). For an uninsured building, that is not a trivial bet. Earthquake endorsements (an add-on to the property policy) tend to carry steep deductibles, commonly 5 to 25 percent of the insured value (California Earthquake Authority). On a $50 million building, a 15 percent deductible leaves the association covering $7.5 million before the policy pays a cent.

A board that declines earthquake coverage in a known seismic zone should record the decision, and why, in the meeting minutes. The "reasonably available" language in RCW 64.90.470 gives boards room when premiums are genuinely out of reach, but an undocumented pass invites a fiduciary claim later. Modeling that deductible against the reserve balance is worth doing before renewal.

What your board should do before 2028

Boards have time before 2028, and the smart play is to close the gap early. Four steps handle most of it.

1. Pin down which act governs you today. Check the declaration's formation date, and whether the board ever opted into WUCIOA under RCW 64.90.370.
2. If you formed before 2018, meet the lender bar first. Fannie Mae's requirements already run ahead of most legacy-act rules, and units have to be financeable now, not just in 2028.
3. Add fidelity coverage if you don't carry it. Fannie Mae's Selling Guide requires it for projects over 20 units, and sizing it to three months of assessments clears both that bar and the 2028 mandate. Our state fidelity bond comparison walks through the math.
4. Settle the owner-upgrade question. If the declaration is silent, WUCIOA's all-in default takes over in 2028, so decide now whether to keep it or opt out.

The WUCIOA insurance requirements are not a 2028 surprise. They already sit in RCW 64.90.470, and the only open question is when they bind your community. Coverwatch reads Washington association policies against both the current act and the 2028 standard, then shops its carrier network to close any gap. Start early, and a renewal-day scramble becomes a planned transition.
