Fremont, CA Home Business: Signage Rules (2026)

Under the Fremont Home Occupation Permit standards, no exterior signage, window lettering, banners, flags, A-frame boards, yard signs, or illuminated displays are permitted for home-based businesses. The fundamental principle is that the home occupation must be incidental and not visible from public rights-of-way. No business logos on the mailbox, no decals on garage doors, and no illuminated building numbers other than standard addresses. Vehicles with commercial lettering must be parked inside a garage if possible or are limited to one such vehicle in the driveway under Fremont Municipal Code. This differs sharply from commercial zones where signs are regulated by square footage. Online signage (Google Business, websites, social media) is unrestricted since those do not alter neighborhood character. Violations are handled by Code Enforcement with a notice to cure followed by administrative fines starting at 100 dollars.
