Because the plug-in provisions were removed before HB 2296's final passage, the enacted chapter did not create a dedicated statewide plug-in-solar exemption.

Existing utility, electrical, building, property, and product-safety requirements still apply.

Before you buy in Washington

This page is informational research, not legal advice — and it can fall out of date quickly. Before installing anything, confirm the current law and its start date, any size limit, your local building and fire codes, your utility’s requirements, that the kit is certified as a complete system, your landlord or homeowners association (HOA) rules, a safe way to mount it, and the maker’s instructions.

A “no dedicated statewide law found” status does not settle those other utility, electrical, building, fire, property, or product-safety requirements.
