Redwood City, CA Home Business: Signage Rules (2026)

12, but the sign rules draw a hard line at advertising them. 72, in the Article III sign code's list of prohibited sign types, names "Home Based Occupation Signs" alongside abandoned signs, billboards, and electronic message signs as categories that may not be installed or maintained anywhere in the City unless another provision expressly allows them. 84, which governs residential signage generally, drives the point home for single-family and multifamily properties: after listing what a home can display, noncommercial speech, real estate signs, garage sale signs, construction signs, and noncommercial flags, it states plainly that signs advertising home occupations are prohibited.

That means a resident running a licensed home-based landscaping business, consulting practice, or cottage food operation cannot post a wall sign, yard sign, or window sign naming or promoting that enterprise, even though the home occupation itself needs no permit under the Zoning Ordinance. 71 supplies the enforcement mechanism: any prohibited sign is subject to immediate abatement by the property owner once the City gives notice. 84, real estate, garage sale, construction, or noncommercial signage, none of which may reference the business being operated inside.
