Rental Regulations Seattle Property Owners Should Be Aware Of

Seattle is known for its dynamic rental market—and equally dynamic rental regulations. Keeping up can be daunting, but compliance is essential for protecting your property and avoiding costly legal issues.

Here are key Seattle rental regulations every property owner should know in 2025:

1. 📋 First-in-Time Rule

Seattle requires landlords to offer the rental unit to the first qualified applicant. This means you must clearly define your rental criteria upfront and apply them consistently.

2. 🔑 Security Deposit Limits

Move-in fees and security deposits combined can’t exceed one month's rent. Deposits must be clearly itemized and returned within 21 days after move-out, minus documented damages.

3. ⚖️ Just Cause Eviction Ordinance

Seattle tenants can only be evicted for specific, legally-defined reasons. Proper notices and documentation are critical to compliance.

4. 📅 Mandatory Notice Periods

Recent laws increased required notice periods, including:

• 180-day notice for rent increases over 10%

• Extended notice periods for lease termination or significant lease changes

5. 🐾 Pet-Friendly Policies

Seattle requires landlords to accommodate service and emotional support animals—even if your property has a no-pet policy. Ensure your lease language complies.

6. 📝 Regular Property Inspections

Routine property inspections must follow strict guidelines, including proper tenant notice. Documenting these inspections protects you legally and financially.
