What the permit record shows
We have permit records for San Francisco and San Jose only. Other Bay Area cities don't publish contractor names in a form we can read, so an empty list here says nothing about work elsewhere.
No permits matched this business in the last 24 months in the San Francisco data (matched by license number) or the San Jose data (matched by business name).
