Richmond, CA Home Business: Signage Rules (2026)

Richmond's Home Occupation Permit conditions, typical of California cities, prohibit any exterior evidence of the business, including signs, lighted displays, window lettering, sandwich boards, banners, or flags identifying the business. Delivery and other routine commercial traffic that would indicate business activity to neighbors is also limited. Vehicles used primarily for the business (plumbing vans, contractor trucks with lettering, etc.) that are stored at the residence may be regulated; typically one business vehicle up to 3/4-ton or smaller is permitted to be parked at the home if otherwise compliant with parking rules. Oversized commercial vehicles may be prohibited from overnight parking in residential zones. The sign restriction reflects California's strong preference for preserving residential character even where home occupations are permitted. Violations typically generate a warning letter from Code Enforcement followed by escalating administrative citations (often $100/$200/$500 under Richmond's citation framework). The First Amendment protects some limited non-commercial signage (for-sale-by-owner, political, religious), which is not subject to the home-occupation sign prohibition. Temporary signage for legitimate events (garage sale, block party) is permitted under separate temporary-sign rules, typically up to 7 days. Online advertising and social media marketing are unrestricted — the prohibition is specifically on physical signage visible from the public right-of-way.
