You did everything right. You raised the rent by an amount that felt fair, gave notice the way you always have, and went about your day. Then you learn the notice fell short of what Washington now requires, and the increase is invalid.
That is the new reality for Bellingham landlords in 2026. The habits that worked five years ago will not protect you today, and that gap is exactly where good landlords lose money they never needed to lose.
This guide covers the rent caps, fees, notices, and inspection standards keeping Bellingham owners compliant this year.
Key Takeaways
Washington's 2025 rent stabilization law caps most annual rent increases at 9.683% for 2026, with a 90-day state notice minimum and a stricter 120-day notice requirement inside Bellingham city limits.
Bellingham's rental fee ordinance limits pet deposits to 30% of monthly rent or pet rent to 2% of monthly rent, never both, alongside caps on security deposits, screening fees, and late fees.
Property inspections have become increasingly important because documentation often determines the outcome of deposit disputes and legal claims.
Working with knowledgeable local property managers can significantly reduce compliance risks and administrative errors.
Understanding Rent Caps and Rent Increase Rules in 2026
Washington has never been a traditional rent control state, but that changed with House Bill 1217, the rent stabilization law signed May 7, 2025. Landlords now face real, enforceable limits on rent increases, and Bellingham owners need to know exactly where those limits sit before touching a lease.
Notice Period Requirements
Any rent increase now requires at least 90 days of written notice statewide, up from the old 60-day standard. Bellingham asks for more: 120 days, no exceptions. Because the city's rule is stricter, it applies inside city limits.
A compliant notice should spell out:
The current rent amount
The proposed rent amount
The effective date
Any changes to additional charges or recurring fees
Miss a detail here, or send the notice too late, and the increase can be thrown out entirely, leaving you back at square one with an unhappy tenant and a paper trail working against you.
Restrictions on Excessive Increases
Here's the number that matters most: under HB 1217, annual rent increases are capped at the lower of 7% plus the change in the Seattle area Consumer Price Index or a flat 10%. Commerce recalculates this figure every year, and for the full 2026 cycle, the maximum allowable increase is 9.683%.
A handful of exemptions exist, though none apply automatically. Properties fall outside the cap if they are new construction with a certificate of occupancy issued within the last 12 years, an owner-occupied duplex, triplex, or fourplex, certain nonprofit or income-restricted affordable housing, or a unit where a tenant shares a bathroom or kitchen with an owner living on site. Claiming one of these means spelling out the supporting facts directly in the notice, not just assuming it applies.
One more trigger worth watching: Bellingham requires relocation assistance whenever a rent increase reaches 8% or more within a rolling 12-month period, equal to three times the tenant's monthly rent or three times HUD fair market rent, whichever is larger. A few extra minutes reviewing where your property lands can save you from a dispute that costs far more than the increase was worth.
Rental Fees: What Landlords Can and Cannot Charge
Few areas of rental housing have tightened up as fast as fees, and Bellingham landlords now have specific dollar and percentage limits to work within.
Application and Screening Fees
Screening costs are still fair game, but only up to what you actually spend. Bellingham caps screening fees at $50 plus the annual change in the local Consumer Price Index, and applicants are entitled to know what they're paying for before you collect a dime.
Before charging a fee, disclose:
The screening criteria
The reports being obtained
The agency conducting the screening
The applicant's rights regarding adverse decisions
Being upfront here does double duty. It keeps you compliant and helps head off discrimination claims before they start.
Late Fees
Late fees are still allowed, but they need to stay reasonable and appear in writing in the lease. Bellingham draws a hard line: a late fee can't exceed 2% of the remaining rent balance.
A well-written late fee policy defines when rent officially becomes late, how the fee gets calculated, whether a grace period exists, and avoids any wording that could be read two different ways. Vague language here is where landlords get burned.
Move-In Fees and Security Deposits
Security deposits come with their own ceiling. In Bellingham, a deposit generally can't exceed one month's rent. Pet owners get their own rules too: charge a refundable pet deposit up to 30% of monthly rent, or pet rent up to 2% of monthly rent, but never both at once.
Before you accept a deposit, make sure you've provided:
A written rental agreement
A detailed move-in checklist
Documentation describing the property's condition
Skip these steps, and you may find yourself unable to withhold a cent for damage later, no matter how justified the deduction feels.
Understanding Notice Requirements Beyond Rent Increases
Rent increases get most of the attention, but notice requirements show up everywhere in the landlord-tenant relationship.
Termination Notices
Termination notices vary depending on the situation, whether it's nonpayment of rent, a lease violation, an end-of-tenancy notice, or an owner-occupancy move-in. Each one calls for specific language and a clear timeline, and a generic template pulled off the internet is a real liability given how often Washington's landlord-tenant law shifts.
Maintenance and Property Access Notices
Entry rules are straightforward once you know them. Washington law requires at least two days' written notice before entering a unit to inspect, repair, or provide a service, and one day's notice to show the unit to a prospective buyer or tenant.
That notice should cover the reason for entry, the date, the approximate time, and how you can be reached. Emergencies are the one exception that allows immediate access.
Required Tenant Disclosures
Washington landlords also owe tenants a handful of standard disclosures covering security deposits, mold, property management contacts, and tenant rights. Building a standardized disclosure packet once and reusing it across every property saves time and keeps you consistent.

Compliance Isn't Paperwork. It's Protection.
The biggest misconception about rental law is that compliance matters only after something goes wrong. In reality, compliance is what keeps problems from becoming disasters in the first place.
Bellingham landlords entering 2026 face the most regulated environment the city has seen. Rent increases now come with real limits, notices demand precision, fees demand transparency, and inspections demand documentation.
The landlords who come out ahead won't be the ones with the biggest portfolios. They'll be the ones who treat compliance as a strategy, not a burden.
