Summary

A licensed 'day care home' is a permitted home occupation in unincorporated Arapahoe County under LDC § 3-3.12.B.1, capped at six children at once if the provider has no school-age children of their own, dropping to zero as the provider's own kids under school age increase.

City-specific rules exist: Aurora, and Centennial have their own home daycare rules that differ from Arapahoe County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

1. Day Care Home A "day care home" (see definitions) shall be permitted subject to the following provisions: ... Such "day care home" shall obtain proper licensing as may be required by Colorado Department of Human Services, and/or any other agency as may be required by Colorado laws. A "day care home" is exempt from the provisions of subsections 3-3.12.A.2.a and 3-3.12.A.2.d through 3-3.12.A.2.g above.

Full Breakdown

g. 1 sets a sliding cap on how many day care children can be present at once based on how many of the provider's own children aren't yet attending full-day school: a provider with none of their own young children can care for up to six day care children, a provider with one can care for five, and so on down to zero day care children permitted if the provider already has six or more children not in full-day school. A second table adds slots for school-age children during school hours.

Every day care home must carry proper licensing 'as may be required by Colorado Department of Human Services, and/or any other agency as may be required by Colorado laws', the county's zoning permission doesn't substitute for state child-care licensing. The code separately recognizes an 'Experienced Family Child Care Provider' tier (six consecutive years of Colorado licensing, 90 hours of training, no substantiated safety complaints or negative licensing actions in the prior two years, and 35/75 square feet of inside/outside space per child) and a larger 'Child Care Home, Large' tier, both of which require Special Exception Use approval from the Board of Adjustment rather than being permitted outright like a standard day care home.

Violations & Fines

Operating a day care home without the required Colorado Department of Human Services (or other applicable state agency) license, or exceeding the child-count limits in Table 3-3.10.1, is both a state licensing violation and a breach of the permitted-use conditions in LDC § 3-3.12.B.1; the county's zoning approval for the use is contingent on that licensing being maintained, and the Experienced Provider and Large Child Care Home tiers additionally require standing Board of Adjustment Special Exception Use approval that can be revisited if conditions aren't met.

Frequently Asked Questions

How many kids can I watch in my home day care in unincorporated Arapahoe County?
It depends on how many of your own children aren't yet in full-day school. Table 3-3.10.1 in LDC § 3-3.12.B.1 allows up to 6 day care children if you have none of your own, dropping by one slot for each of your own children not in full-day school, down to zero if you have 6 or more.
Do I need a state license to run a day care home in the county?
Yes. Section 3-3.12.B.1 requires that a day care home 'obtain proper licensing as may be required by Colorado Department of Human Services, and/or any other agency as may be required by Colorado laws,' on top of meeting the county's zoning conditions for the use.
Can I put up a sign advertising my home day care?
No. LDC § 3-3.12.B.1 states 'such "day care home" shall not be allowed signage,' the same no-advertising position the county applies to home occupations generally.
What if I want to care for more children than the day care home limits allow?
You'd need to qualify as an Experienced Family Child Care Provider or a Child Care Home, Large under LDC § 3-3.12.B.2-3, both of which require Board of Adjustment approval as a Special Exception Use plus additional Colorado licensing and training conditions.
