A live-in nanny gives a family flexibility, but it blurs the line between work and home. The arrangements that last have clear hours, real private space and written expectations.
| Live-in nanny | Live-out nanny | Au pair | |
|---|---|---|---|
| Lives with you | Yes | No | Yes |
| Relationship | Your employee | Your employee | Cultural exchange through a sponsor program |
| Hours | Set by your agreement and the law | Set by your agreement and the law | Capped by program rules |
| Experience | Can be very experienced | Can be very experienced | Usually young; varies widely |
See is an au pair right for us? if you're weighing that route.
Living in doesn't make her on duty around the clock. Agree on a working schedule and protect her time off. Federal and state rules for live-in workers differ, and some states, including New York and California, have specific requirements. Don't assume room and board can be counted toward wages; the rules are strict.
Pay, tax and labor rules vary by state and city. This guide explains common practice; a household payroll provider, accountant or your state labor department can confirm what applies to you.


Tammy Gold, LCSW, spent years matching families with nannies before writing Secrets of the Nanny Whisperer (Penguin). Today she works beside families, and their agencies, as a neutral expert: defining the job, interviewing candidates, checking references and setting up the first 30 days.
She's an adult, not a family member you supervise. Agree on guests, quiet hours and how you'll handle the gray areas: being home but off duty while the kids look for her. Write it down, and revisit it after the first month.
Not necessarily. Room, food, utilities, a car and the legal requirements add up. Compare the full cost, not just the hourly rate.
Only under strict rules. Ask a payroll provider before you count anything toward wages.
Put notice terms and a move-out timeline in the agreement before she moves in, so an ending is respectful for everyone.
Hours, space and house rules agreed before move-in day.
