It is 12:40 a.m. on a Saturday and you are lying awake, listening for the garage door, unsure whether you are even allowed to have an opinion about when your 24-year-old au pair comes home. Here is the fact that reframes the whole question: most au pair matches that fail do not fail over childcare. Industry estimates put rematch at 15–25% of placements, and the conflicts that get families there are overwhelmingly house-life conflicts — the car, the kitchen, the overnight guest, the rules nobody ever wrote down.
The fix is unglamorous and remarkably effective: a written house rules handbook, shared before you match, walked through in week one, and revisited at day 30. This guide covers what belongs in one — the 8 sections, the curfew myth that trips up half of first-year host families, and how to calibrate rules for a 19-year-old from Hamburg versus one from São Paulo. If your match is already wobbling, start with our au pair rematch guide; this article is about never needing it.
An au pair house rules handbook is a short living document — 8 sections covering daily rhythm, kitchen, guests, car, alcohol, phones, travel, and communication — shared before matching, not after arrival. You cannot set a curfew on an adult's free time, but you can set a car curfew, quiet hours, and a guest policy. No house rule can create unpaid work: any time spent minding your children counts toward the 45-hour weekly cap. Families who put expectations in writing before matching avoid the most common causes of the 15–25% of placements that end in rematch.
What Is a Host Family Handbook — and Why the Contract Isn't Enough
Your au pair contract is the legal skeleton of the year: schedule, stipend, duties, car clause, termination terms. Its house rules section is deliberately brief, because a signed agreement is the wrong place to explain how your household actually feels about shoes past the entryway or a boyfriend at Sunday breakfast.
The handbook is the other document. It is not signed, it is not legal, and that is precisely its value: it can be warm, specific, and revised in month four without anyone calling the sponsor. The contract says the family car has a midnight curfew; the handbook explains that the curfew exists because the garage door rattles directly under the baby's room. Rules with reasons get followed. Rules without reasons get tested.
One document protects both sides if things go wrong. The other keeps things from going wrong. You need both, and they should agree with each other.
The Curfew Myth (and Two Others Worth Retiring)
Myth 1: You can set a curfew for your au pair. You cannot. She is an adult participant in a State Department cultural exchange, and sponsors are explicit that her off-duty time is genuinely her own. What you can set is a curfew for your car — midnight on work nights and 1 a.m. on off nights is the common pattern — along with quiet hours in shared spaces and a guest policy for your home. Govern the house and the vehicle, not the person. In practice, that one distinction defuses the most resented rule in the program.
Myth 2: "Pitching in" can be a house rule. A rule that everyone clears their own dishes applies to her as a member of the household. "Keep an ear out for the kids while I run to the gym" does not — that is childcare, it counts toward the 45-hour week, and it belongs on the schedule. Our au pair schedule and hours guide covers the caps in detail; the handbook's job is to never quietly violate them.
Myth 3: More rules mean fewer problems. A 25-rule handbook reads like boarding school, and an au pair who feels policed at week two is browsing rematch forums by week eight. Aim for two to three pages. Every rule you write is a rule you have committed to explaining, and enforcing, for twelve months.
Cultural Calibration: "Normal" Depends on the Passport
Before you write a single rule, consider what it will sound like to the person reading it — her baseline for normal was set 5,000 miles from your kitchen.
A 19-year-old German au pair has been legally drinking beer and wine since 16, has probably traveled across Europe without an adult, and has not had a curfew since early Gymnasium. A blanket alcohol ban reads to her as infantilizing. A rule of "never on duty, never before driving, moderate at home" reads as professional — and gets kept.
A young Brazilian au pair often arrives from a household where meals are long and loud and friends drop by unannounced as a feature of family life, not an intrusion. Your quiet 6:15 dinner and appointment-only guest policy are not neutral to her; they can read as coldness, or as suspicion. She may keep every rule perfectly and still feel lonely inside them — which is its own quiet path to rematch.
These are honest generalizations, not predictions; individuals vary enormously. The point is not to profile your au pair. The point is that your "obvious" is not her "obvious," and a handbook that explains the why behind each rule does the cultural translation for you.
The 8 Sections of a House Rules Handbook (Template)
Keep the finished document to two or three pages, written in the voice you would use across the kitchen table. Here is the outline the Beverly team recommends — adapt the specifics, keep the structure.
- Welcome and how our home runs. One warm paragraph: who you are as a family, what matters most to you (the toddler's 7 p.m. bedtime is sacred; Sunday mornings are slow), and that this document exists so she never has to guess.
- Daily rhythm and quiet hours. Wake-up times, quiet hours (9:30 p.m. is typical with young children), shared-bathroom choreography, and which spaces are hers without asking.
- Kitchen and food. What is shared versus reserved, how grocery requests work, whether she is expected at family dinner and how often, and any allergy, kosher, or dietary lines that are absolute.
- Guests and visitors. Friends in common areas until a set hour, advance notice for overnight guests, and your policy on a boyfriend or girlfriend staying over. Decide this before it happens — it is the most awkward rule to invent live.
- The car. Approved uses, the car curfew, fuel, phone rules, and passengers — summarized here, with the full decision framework in our au pair driving and car insurance guide.
- Alcohol, smoking, and substances. No smoking in the house or car; alcohol only off duty and in moderation; zero alcohol before driving or childcare. Add the note many families miss: cannabis being legal in your state does not make it safe for her — use can carry real immigration consequences for a visa holder.
- Phones, social media, and the kids. No posting the children's faces, full names, school, or home location; phone expectations during duty hours (reachable always, scrolling at naptime only).
- Travel, weekends, and time off. How far ahead to flag a weekend trip, overnight-away etiquette, and how family-trip invitations work — the working-versus-guest distinction is covered in our guide to traveling with your au pair.
The handbooks that work sound like the family that wrote them. When one opens with "We're loud, we're usually five minutes late, and the dog is allowed on exactly one couch," that match has a head start — the family has told the truth about itself in writing.

Program regulations outrank anything in your handbook. An au pair works at most 45 hours per week and 10 hours per day, gets a day and a half off each week, one full weekend off per month, and two weeks of paid vacation — and no house rule can waive any of it.
The gray zone is presence versus duty. If she joins family dinner as a member of the household, that is life, not work. If she is expected at breakfast because someone needs to spoon-feed the two-year-old while you take a call, that is childcare and it goes on the schedule. The honest test: if she could not leave the room without consequence, she is working. Your handbook should simply point to her posted weekly schedule rather than restate it.
Share It Before You Match — Then Keep It Alive
Send the handbook before the second video call, alongside your written duties list. A candidate who reads your real rules and keeps leaning in is opting in with full information; the one who would have chafed under your guest policy opts out at zero cost to anyone. Families who share expectations only after arrival are asking a 20-year-old to discover the rules by breaking them.
Then treat it as living. Walk through it in person during week one, next to the duties and responsibilities list that covers the childcare side. At the day-30 check-in, ask which rules are not working, and revise. A rule you quietly stopped enforcing in October is a trap for the au pair who still believes it in March. A handbook that never changes is a handbook nobody is reading.
The Bottom Line: Write Down the Unwritten
Every family has house rules; the only question is whether your au pair gets to read them or has to guess them. Guessed rules fail slowly — a skipped dinner here, a too-late Friday there — until both sides feel wronged at once. Written rules fail fast and cheap: on a video call, before anyone boards a plane.
When Beverly coordinates an au pair search, the handbook goes into the matching packet before interviews begin, because the cheapest rematch is the one that never happens. Write yours this weekend. Two pages, eight sections, one honest voice.
