What this is
When a homeowner installs solar, the contractor pulls a building or electrical permit with the local jurisdiction, and that filing becomes public record. Solar permit data is the structured, searchable version of those filings. Each record names the address, the filing date, the permit type, and the installing contractor. For Washington, SolarLead tracks 22,398 of these, adding new ones the day they are filed.
A permit means a homeowner already chose solar and committed money, which is a far stronger signal than a shared lead-gen list. Installers use Washington permit data to find fresh installs for referral and service offers, to spot battery-retrofit candidates as systems cross the 2 to 5 year mark, and to watch which contractors are gaining or losing ground across the area. It is a record of decisions, not a list of maybes.
Washington permits refresh daily. The 58 figure above counts permits filed in the trailing 30 days, and 16 landed in the last week. Every record keeps its own filing date so freshness is never a guess.
