Launch markets

Five counties. Thousands of permits. All tracked automatically.

InstaPermit starts where California's permit volume is highest — then expands to cover all 58 counties.

Highest volume

Los Angeles

LADBS + 88 incorporated cities

Los Angeles is the largest permit market in the country. LADBS alone processes tens of thousands of permits annually, and the 88 incorporated cities within LA County each maintain their own building departments and portals.
