Summary
Unincorporated Yolo County treats small family daycare as a by-right residential use under state law: any home caring for eight or fewer children needs no zoning approval. Cross the eight-child line and Sec. 8-2.506(g) requires a Site Plan Review addressing density, traffic, parking, and noise before the larger operation can open.
(g) Child care. Home child care is an allowed “by right” use in all zones if the facility cares for eight (8) children or less, as required by State law (California Health and Safety Code Section 1597.45). Large child care facilities in a residence with more than eight (8) children and up to fourteen (14) children are allowed with the issuance of a Site Plan Review in the A-N, A-X, RR-5, RR-2, R-L and R-M, and in specified commercial zones, provided that the project is designed to address impacts related to density, traffic, parking, and noise.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: 2026 S-21: Supplement 2026 S-21 includes: Local legislation current through Ord. 1584, effective June 25, 2026).
Full Breakdown
Sec. 45. No use permit review is required for a small provider at that scale. Once a home cares for nine to fourteen children, it becomes a "large" family child care facility and needs a Site Plan Review in the A-N, A-X, RR-5, RR-2, R-L, R-M zones, and in specified commercial zones. The Planning Director evaluates that Site Plan Review against four impact categories written into the code: density, traffic, parking, and noise, and can require a discretionary Minor Use Permit instead if the proposed large facility creates problems in any of those four areas that conditions of approval must address.
Anything larger than fourteen children is reclassified under Sec. 506(h) as a nonresidential "child care center," which needs its own Site Plan Review in the RR-5, RR-2, R-M, and R-H zones and specified commercial zones, plus a Minor Use Permit for centers under twenty children or a Major Use Permit for centers over twenty. Every tier of review must find the facility compatible with adjoining single-family homes and confirm adequate on-site services such as leachfields where the parcel is not connected to public sewer.
Violations & Fines
Operating a large family daycare or child care center without the Site Plan Review or Use Permit that Sec. 8-2.506(g)-(h) requires is a zoning violation the Planning Director enforces under Sec. 8-2.226(a). Conviction is a misdemeanor under Sec. 8-2.226(c), carrying up to a $500 fine, up to six months in county jail, or both under Sec. 1-2.01, with each day of continued operation counted as a separate offense.
