Walnut Creek, CA Home Business: Home Daycare (2026)

Family day care operation in Walnut Creek is governed primarily by California state law, which strongly preempts local regulation. Under Health & Safety Code §1597.45, a small family day care home (serving up to 8 children including the provider's own) must be treated as a residential use of property for zoning, building, and fire code purposes. Cities cannot require conditional use permits, business licenses more restrictive than other home uses, or impose spacing requirements between homes. A large family day care home (9–14 children) was historically treated similarly; under the updated state law (SB 234, effective 2020), it is now also a by-right residential use statewide, removing prior conditional use permit requirements. Providers must obtain a Family Child Care Home license from the California Department of Social Services, Community Care Licensing Division. Licensing standards include criminal background checks for all adults in the home (TrustLine/LiveScan), tuberculosis clearance, CPR and first aid certification, pediatric CPR, and mandated reporter training. The home must meet state physical standards: functional smoke alarms and carbon monoxide detectors (see building-safety), secure storage of hazardous substances, pool fencing per HSC §115920 if applicable, and fenced outdoor play space. Walnut Creek may conduct a fire clearance inspection (Contra Costa County Fire Protection District for large homes) but cannot deny operation based on neighborhood opposition or density. Parents must be given licensing information and the provider cannot exceed ratios or hours specified in the license.
