Washington lawmakers tried to legalize balcony solar in 2026 and did not get there. This guide is as of October 2026. It is not legal advice, so check your utility's page before you buy.
Is balcony solar legal in Washington now?
There is no state law that allows it. HB 2296 and its companion SB 6050 were broad energy bills with plug-in solar language. The House committee removed that language on February 2, 2026. SB 6050 went to the Senate Rules Committee and was dead by February 26, 2026. The session ended in March. See which states allow balcony solar.
How many watts could I plug in in Washington?
No limit is set, because no law passed. The bills as filed proposed up to 1,200 watts with UL 3700 certification, or a smaller 391 W option. The House bill that did pass is a rental-housing efficiency law, Chapter 136 of the 2026 laws. It has no plug-in rules.
Do I need to tell my utility in Washington?
Yes, plan on it for a grid-tied system. Without a plug-in law, the normal utility connection process applies. Rules differ between big utilities, public utility districts and co-ops. We did not verify each one. Call yours first.
Can my landlord or HOA say no to balcony solar in Washington?
Yes. No law gives renters or HOA members a right to plug in. Ask in writing before you buy. Our renters guide has a checklist.
