1. Why this disclosure requirement targets the lease, not the listing
The statute requires this disclosure in the rental agreement itself; it doesn't extend the requirement to advertisements or listings used before a lease is signed.
[Cite: RCW 59.18.060(13), as amended by S.S.B. 6237, 2026 Wash. Sess. Laws, c. 234]
That scope matters practically; a landlord satisfies this requirement by including the required language in the written lease a tenant actually signs, and doesn't need to retrofit marketing copy, listing descriptions, or earlier advertising materials to include the same disclosure.
2. Why the disclosure covers possession insurance, not just the flood risk itself
Beyond flagging the flood-hazard risk, the statute specifically requires telling tenants that the landlord's insurance doesn't cover their personal belongings, and that they should consider renter's and flood insurance.
[Cite: RCW 59.18.060(13)]
That second element addresses a common and costly misunderstanding; a tenant who assumes a landlord's property insurance covers their own furniture, electronics, or other belongings in the event of a flood is operating on a mistaken assumption this disclosure is specifically designed to correct before any loss happens.
3. Why pointing tenants toward county resources, rather than providing hazard data directly, is the chosen approach
Rather than requiring a landlord to independently research and state detailed flood-hazard data, the statute requires directing tenants to county government resources for that information.
[Cite: RCW 59.18.060(13)]
That structure puts the burden of maintaining current, accurate hazard data on the government resource best positioned to keep it updated, rather than requiring every individual landlord to become a flood-risk research expert; a landlord satisfies this element by naming the correct county resource, not by summarizing floodplain maps themselves.
4. Why the law stops short of requiring a certainty-of-flooding statement
The statute doesn't require a landlord to certify that flooding will actually happen, only that the property may be located in a special flood hazard area or an area of potential flooding.
[Cite: RCW 59.18.060(13)]
That "may be" framing is deliberate; a landlord isn't being asked to predict future flooding events or make a definitive factual claim about flood certainty, just to disclose the property's flood-hazard-area status as a known possibility a tenant should factor into their own insurance decisions.
5. Why the bill's legal effective date and the disclosure's applicable date are 2 different things
The bill itself became law on June 11, 2026, but the actual disclosure obligation applies specifically to leases entered into after December 31, 2026.
[Cite: S.S.B. 6237, 2026 Wash. Sess. Laws, c. 234, Sec. 1]
A landlord shouldn't assume this requirement is a distant 2027 concern simply because the statute was signed back in June 2026; the operative deadline that actually matters for compliance purposes is the December 31, 2026 cutoff for new lease signings, not the earlier date the bill became law.
6. Why existing leases signed before the cutoff don't need retroactive amendment
Since the requirement applies to leases "entered into after December 31, 2026," a tenancy already under a signed lease before that date isn't required to be amended or reissued solely to add this disclosure.
[Cite: RCW 59.18.060(13)]
A landlord managing a large portfolio with staggered lease-renewal dates should expect this requirement to phase in gradually as individual leases come up for renewal or new signing after the cutoff, rather than applying to every active lease on a single fixed date.
7. Why renewals, not just brand-new tenancies, likely trigger this requirement
Because the statute's trigger is a lease being "entered into," a lease renewal signed after December 31, 2026, functions as a new lease-signing event for purposes of this disclosure requirement.
[Cite: RCW 59.18.060(13)]
A landlord renewing an existing tenant's lease after the cutoff date should include this disclosure in that renewal document, treating the renewal signing the same way a brand-new tenancy's initial signing would be treated under this provision.
8. Why the immunity provision matters for landlords acting in good faith
A landlord has protection from civil liability for an omission of this disclosure unless that omission is knowing and intentional.
[Cite: S.S.B. 6237, 2026 Wash. Sess. Laws, c. 234]
That standard distinguishes an honest administrative oversight, a lease template that simply hadn't been updated yet, from a deliberate decision to withhold known flood-risk information from a tenant; a landlord still has real incentive to update lease templates promptly, since the immunity doesn't cover a knowing and intentional failure to disclose.
9. Why confirming a property's actual flood-zone status is the necessary first step
Before a landlord can accurately complete this disclosure, the landlord needs to actually determine whether a given property sits within a special flood hazard area or an area of potential flooding.
[Cite: RCW 59.18.060(13)]
A landlord managing multiple properties should check each one's flood-zone status individually against FEMA flood maps or the relevant county hazard resource, rather than assuming a blanket answer across an entire portfolio, since flood-risk designation varies significantly even within the same general area.
10. Why lease-template updates should happen well before the December 2026 cutoff
Since the disclosure requirement applies to any lease entered into after December 31, 2026, a landlord needs updated lease language ready and in active use before that date, not scrambled together as the deadline arrives.
[Cite: RCW 59.18.060(13)]
A landlord relying on a property manager or leasing software to generate lease documents should confirm that template has been updated to include the required flood and insurance language well ahead of any lease-signing scheduled for January 2027 or later.
11. What property managers should do now
The practical starting point is checking each property's flood-hazard-area status against FEMA maps or the applicable county resource, so the disclosure that eventually goes into the lease is actually accurate for that specific property.
Updating lease templates now, rather than waiting until late 2026, gives a portfolio manager time to confirm the required language is correctly in place before any lease signing or renewal that falls after the December 31, 2026 cutoff.
Frequently asked questions
When does Washington's flood-risk disclosure requirement apply?
To leases entered into after December 31, 2026. The underlying bill itself became law earlier, on June 11, 2026.
What exactly does the disclosure have to say?
That the property may be in a special flood hazard area or area of potential flooding, that the landlord's insurance doesn't cover the tenant's belongings, and that county resources have more flood-hazard information.
Does this apply to my current lease if I signed before 2027?
No. The requirement applies to leases entered into after December 31, 2026; an existing lease signed earlier doesn't need to be amended solely for this disclosure.
Does a lease renewal count as a new lease for this requirement?
Yes. A renewal signed after the cutoff date functions as a lease-signing event that triggers the disclosure requirement.
Is a landlord required to buy flood insurance because of this law?
No. The law requires disclosure and a recommendation that tenants consider their own insurance; it doesn't require the landlord to purchase or carry flood insurance.
What protection does a landlord have if the disclosure is accidentally left out?
A landlord has immunity from civil liability for an omission unless that omission is knowing and intentional.
