Renton FAQ
Can my Renton HOA ban solar panels?
No. RCW 64.38.055 and RCW 64.90.560 make HOA rules that unreasonably restrict residential solar systems unenforceable.
Can the HOA block my ADU if the city allows it?
Not broadly. HB 1337 and Renton's 2025 code allow at least 2 ADUs per single-family lot, and HOA CC&Rs that conflict with the mandate are likely unenforceable.
Seattle FAQ
Can a Seattle HOA deny all exterior modifications?
Associations may regulate modifications but must apply standards consistently and reasonably. Blanket prohibitions without documented guidelines may be challenged under WUCIOA.
Can I attend my HOA's architectural review committee meetings?
Yes. Under WUCIOA, all committee meetings including architectural review must be open to unit owners.
