Summary

Ontario follows California law classifying small and large family daycare homes as residential uses. State statutes preempt most local zoning, but fire clearance and basic home-occupation registration still apply.

Health and Safety Code - HSC. DIVISION 2. LICENSING PROVISIONS [1200 - 1796.88]. CHAPTER 3.6. Family Day Care Homes [1597.30 - 1597.622]. 1597.40. (a) It is the intent of the Legislature that family daycare homes for children should be situated in normal residential surroundings so as to give children the home environment that is conducive to healthy and safe development. It is the public policy of this state to provide children in a family daycare home the same home environment as provided in a traditional home setting. (b) The Legislature declares this policy to be of statewide concern with the purpose of occupying the field. This act, the state building code, and the fire code, and regulations promulgated pursuant to those provisions, shall preempt local laws, regulations, and rules governing the use and occupancy of family daycare homes. Local laws, regulations, or rules shall not directly or indirectly prohibit or restrict the use of a facility as a family daycare home, including, but not limited to, precluding the operation of a family daycare home. (Repealed and added by Stats. 2019, Ch. 244, Sec. 6. (SB 234) Effective January 1, 2020.)

Full Breakdown

California Health and Safety Code sections 1597.40 through 1597.465 classify small family daycare homes (up to 8 children) and large family daycare homes (up to 14 children) as residential uses of property. The City of Ontario cannot require a conditional use permit, zoning variance, or business license that treats these homes differently from any other single-family residence. Large family daycare homes are subject to a non-discretionary ministerial permit that focuses on fire and life safety and basic zoning compliance. Operators must obtain a Community Care Licensing Division license from the California Department of Social Services before opening. The Ontario Fire Department conducts the fire clearance inspection for large homes verifying smoke alarms, carbon monoxide detectors, two means of egress from any room used for napping, and current fire extinguishers. Contact Ontario Planning at (909) 395-2000 before operating.

Do I need a business license from Ontario?
A basic home occupation registration applies, but the city cannot impose daycare-specific restrictions beyond what state law allows.
