Exterior signage identifying or advertising a home occupation is prohibited in Oakley. The zoning code requires home businesses to be invisible from the street, with no signs, window displays, or exterior storage of business-related materials permitted on residential property.
Under Oakley Municipal Code Section 9.1.1008, home occupation performance standards expressly prohibit any exterior indication that a business operates on the premises. This includes yard signs, wall-mounted signs, window lettering, vehicle graphics on permanently parked commercial vehicles, and display of merchandise or equipment outside. The intent is to preserve the single-family residential appearance and character of Oakley neighborhoods. This rule applies to all zoning districts that permit home occupations, including RS (Residential Single Family) and RM (Residential Multi-Family) zones. One commercial vehicle (typically up to 3/4 ton and not exceeding normal passenger vehicle dimensions) used by the resident for the business may be parked on-site but must not display prominent business advertising that dominates the vehicle exterior. Mailing and telephone listings are permitted since they are off-site identifiers. For outdoor signage permitted on lawful commercial properties, Oakley's broader sign regulations in Chapter 9.1.1018 govern permits, size limits, illumination, and placement. Violations trigger notices of violation and administrative citations until the offending sign is removed.
