Why This Matters
With rental demand high in Western Washington, some owners consider converting
basements, garages, or attics into rental units without permits. While this may seem like an
easy way to generate income, it can lead to costly legal and financial consequences.
Washington Legal Requirements
Landlords must comply with zoning, permitting, and safety codes. For example, RCW
59.18.085 states that landlords may be liable for damages if tenants are displaced from illegal
units. Requirements such as adequate exits, windows, and ceiling heights cannot be
overlooked. Cities like Seattle and Tacoma have strict ADU and DADU (Detached Accessory
Dwelling Unit) ordinances, and violations often result in fines or forced tenant relocation.
Risks of Noncompliance
Owners who rent illegal units face lawsuits, fines, and potential eviction liability. Tenants
renting such units often have strong legal protections, and courts are unlikely to favor
landlords in disputes. Utility billing disputes and unsafe conditions can further complicate
matters.
The Safer Path
Compliance ensures both tenant safety and investment security. The short-term income from
an unpermitted rental rarely outweighs the long-term risks.
