Hayward, CA Home Business: Zoning & Home Occupation Permits (2026)

3510 defines a home occupation as any occupation run inside the living area of a dwelling by the people who live there, so long as it stays clearly incidental and secondary to residential use and does not change the home's residential character; a licensed group home does not qualify. To stay legal, the business cannot use any yard space or operate outside the dwelling, cannot generate more traffic than is normal for the residential area, cannot occupy more than 10 percent or 200 square feet of the unit's floor area, whichever is smaller, cannot display any sign or vehicle marking that reveals a business is there, and cannot bring in employees who are not residents of the home.

040 spells out the Downtown-specific version: it requires a business license under Chapter 8-1 of the Hayward Code, bars uses like vehicle repair, teaching classes of more than six people, on-site vehicle-related work, and boarding animals for profit, and lets Downtown home occupations in the Urban Neighborhood, Downtown Main Street, and Urban Center zones employ up to two non-resident workers, while the Neighborhood Edge and Neighborhood General zones limit staff to residents only. 040(G).
