How to Run a Background Check and Verify Nanny References
Background checks and reference calls are the last line of defense before you let someone into your home. Here is how to do both properly.
What a nanny background check should include
A standard consumer background check is not enough for in-home childcare. At minimum, look for: criminal history at county, state, and federal level; motor vehicle record if they will be driving; sex offender registry check; and Social Security trace to verify identity.
In California, Trustline is the gold standard. It includes DOJ, FBI, and the Child Abuse and Neglect Reporting Act (CANRA) index. A Trustline-registered nanny has cleared checks that a standard commercial report does not cover.
How to check a nanny's references
Call the reference directly. Email allows people to give non-answers. On a call, you can hear the hesitation.
Questions to ask:
- How long did they work for you and what were their main responsibilities?
- How did they handle a difficult situation — a sick child, a schedule change, a disagreement?
- Why did the position end?
- Would you hire them again without hesitation?
- Is there anything I should know before I make a decision?
That last question opens the door to things people would not volunteer otherwise.
Frequently asked questions
How long does it take to hire a nanny in Los Angeles?
Most full-time placements take 4 to 8 weeks from first consultation to start date. Part-time and temporary roles can move faster. Specialized roles like ROTA or newborn care typically take longer due to a smaller candidate pool.

Our primary focus is Los Angeles and surrounding areas. We occasionally place for families with out-of-area or travel needs. Contact us to discuss your specific situation.
Do I need to pay a placement fee to hire a nanny?
Yes. Placement agencies charge a fee, typically 15 to 20% of the nanny's first-year gross salary. This covers candidate sourcing, vetting, TrustLine verification, reference checks, and the placement process. The fee is paid by the family after a successful placement.

How long does hiring a nanny in Los Angeles take?

What are the real costs of hiring a nanny in Los Angeles?
Beyond hourly pay, expect: employer payroll taxes (roughly 10 to 12% of gross wages), paid sick leave (required by California law), 10 days paid vacation (competitive standard), and potentially a health contribution. Placement agency fees are typically 20% of first-year gross salary.
How do I keep a great nanny long-term?
Competitive pay, consistent communication, clear boundaries, and genuine appreciation are the biggest factors. Annual raises (3 to 5% is standard), acknowledging milestones, and giving adequate notice of schedule changes all contribute to long-term retention.
Should I hire a nanny through an agency or a job board?
An agency pre-screens candidates and presents only those who are a realistic match. A job board gives you a larger unfiltered pool to manage yourself. For first-time household employers or families who want the process handled properly, an agency is strongly recommended.
What should a nanny work agreement include in California?
A California nanny work agreement should include the hourly rate, pay schedule, guaranteed hours, overtime terms (1.5x after 9 hours per day or 45 per week), sick leave (5 days minimum required by law), duties, confidentiality terms, notice period, and termination conditions.
What is the difference between a nanny and a babysitter?
A nanny is a professional caregiver employed on a regular ongoing schedule with formal employment terms. A babysitter provides occasional, informal care. In California, nannies are household employees with legal obligations around pay, taxes, and benefits. Babysitters typically are not.
