We publish counts by ZIP code and by contractor, not a list of permits by street address. The full record for one property, with every permit, its status and its inspections, is kept by the office that issued the permits; our source here is Marin County Community Development Agency building permits on homes in unincorporated Marin (the County's open-data permit and inspection files). Ask that permit office for a property's permit history, or search its public records by address.

Source: Marin County Community Development Agency building permits on homes in unincorporated Marin (the County's open-data permit and inspection files). The window is October 2023 through September 2026. Each permit is placed by its property's ZIP code (the address on the permit, or the parcel's when the permit has none).
Counted: permits on homes for the 15 kinds of work we track (roofing, HVAC, electrical, solar & battery, kitchen, bath & remodel, windows & doors, water heater, plumbing & gas, foundation & retaining wall, EV charger, siding & stucco, pool & spa, decks & stairs, addition, ADU) where the record names a contractor. Not counted: commercial work, trades we don't read, and permits with no contractor (owner-pulled work). So this is not the county's count of every permit in 94920.
A ZIP code does not follow city or county lines; these count only permits in unincorporated Marin County. Counts are permits, not jobs: one job can need several permits.
Nobody paid to be on this page and nobody can.
