The full public record

Updated Nov 6, 2026 · every fact links to its source

California CCLD licensing visits since 2021 (inspections, complaint investigations and follow-ups), updated daily. Citations are matched to the latest visit on or before their correction due date, because the state download does not link them; Type A (immediate risk) and Type B totals are shown per visit kind.

Citations by visit kind (state totals)

Visits	Count	Type A	Type B
Licensing inspections	5	0	1
Complaint investigations	6	1	0
Other (follow-up, case management)	15	5	4

Type A: an immediate risk to children’s health, safety or rights. Type B: a potential risk if not corrected. California publishes these as totals, not per citation.
