Summary

Unincorporated Marin allows small family day-care homes (six or fewer children) and large family day-care homes (eight to fourteen children) by right in any single-family residence in an agricultural or residential zoning district, per Development Code Section 22.32.050. No zoning permit is required beyond the state-mandated California Department of Social Services license; a stand-alone day-care center instead needs a Use Permit.

City-specific rules exist: San Rafael has its own home daycare rules that differ from Marin County's county-level regulations. If you live in San Rafael, check the city-specific page instead.

As provided by State law (Health and Safety Code Sections 1596.78, et seq.), small and large family day-care homes are allowed within any single-family residence located in an agricultural or residential zoning district. Child day-care centers are allowed in the zoning districts determined by Article II (Zoning Districts and Allowable Land Uses), subject to Use Permit approval, in compliance with Chapter 22.48 (Conditional Use Permits)... Large Family Day-Care Home (land use). This land use consists of a day-care facility located in a single-family residence where an occupant of the residence provides care and supervision for eight to 14 children... Small Family Day-Care Home (land use). This land use consists of a day-care facility located in a single-family residence where an occupant of the residence provides care and supervision for either six or fewer children, or eight or fewer children provided that no more than two of the children are under the age of two and at least two of the children are over the age of six.

Full Breakdown

78 and following) allows. 030 as facilities where an occupant cares for six or fewer children, or up to eight children if no more than two are under age two and at least two are over age six, are allowed by right in a single-family residence in any agricultural or residential zoning district. Large family day-care homes, caring for eight to fourteen children in a single-family residence, are likewise allowed by right in the same districts; children under ten who live in the home count toward the total served.

48 (Conditional Use Permits). Every child day-care facility, regardless of size, must first obtain a license from the California Department of Social Services and present proof of that license to the Community Development Agency before opening. Applicants for a day-care center should expect the Agency to weigh site plan, parking, and neighborhood-compatibility factors typical of a discretionary Use Permit review, on top of the licensing step every category of child day care in the county must clear.

Violations & Fines

Operating a child day-care center in unincorporated Marin without the required Use Permit, or without a current California Department of Social Services license on file with the Community Development Agency, is a zoning violation the Agency can pursue through code enforcement, including permit revocation or citation. Small and large family day-care homes that exceed the state-defined child counts for their category lose by-right status and must instead qualify, and permit, as a day-care center.

Frequently Asked Questions

Do I need a county permit to run a small family day-care home in unincorporated Marin?
No. Development Code Section 22.32.050 allows a small family day-care home caring for six or fewer children (up to eight under the mixed-age exception) by right in any single-family residence in an agricultural or residential zoning district; you still need the state Department of Social Services license before opening.
How many children can a large family day-care home serve in Marin County?
Eight to fourteen children, per the Development Code Definitions in Section 22.130.030, provided the home operates in a single-family residence in an agricultural or residential zoning district; children under age ten who live in the home count toward that total.
What's different about a child day-care center?
A center serves 15 or more children and is treated as a commercial or nonprofit land use. It's only allowed in zoning districts listed in Article II and requires a Use Permit under Chapter 22.48 (Conditional Use Permits), on top of the state license every day-care facility needs.
Who enforces day-care licensing in Marin?
The California Department of Social Services issues and enforces the childcare license itself; Marin County's Community Development Agency separately confirms that license is on file before a facility opens and enforces the Development Code's zoning and permit requirements.
