Housesitting in the United States

The '30 days' thing is real but badly misreported. After about a month an occupant can become a tenant-at-will who must be formally EVICTED through a court — no changing the locks, no putting their bags on the kerb — and California and New York are the strictest. That's a due-process delay, NOT ownership: actually owning a home by occupying it (adverse possession) takes years of continuous, exclusive possession, usually while paying the property taxes — not a housesitting scenario. A clear, dated, no-rent licence that says in terms 'this is not a lease' keeps a sit well clear of all of it.

An ESTA authorises travel and lets you request entry as a visitor — it doesn't authorise the activity or guarantee admission, and there's no appeal from a refusal. US border officers have treated housesitting-for-accommodation as unauthorised work, because free lodging counts as compensation for 'productive activity.' An Australian sitter was pulled at Los Angeles in 2022, held for hours, removed, and barred from the visa-waiver scheme — and her sit wasn't even in the US, just disclosed in transit. There's no housesitting visa. If a sit is part of your trip, a border officer may treat it as work: answer their questions truthfully, and weigh that risk before you book.

Disclosed cameras are normal; audio is the trap, and it's state-by-state. Federal law needs only one party's consent, but about a dozen states require EVERYONE's — ten of them beyond dispute (California, Florida, Illinois, Massachusetts, Pennsylvania and Washington among them) — and there, secretly recording a sitter's conversations is both a crime and a civil claim (California's Penal Code §632 is a felony-level offence with statutory damages). In every state, a hidden camera in a private space like a bedroom or bathroom is criminal voyeurism. So 'anywhere, anything' is wrong wherever you are — and a crime in a dozen states.

About four in ten American adults live in a home with a gun (Pew Research, 2023). Owners often don't think to mention them, and we haven't found a general rule that says they must. The safe course is simple: don't handle or move them, keep them away from any children or visitors you bring, and ask the owner up front whether anything needs securing. Rules on storing guns safely vary by state.

Recreational cannabis is legal under STATE law in about two dozen states, and medical use in most of the rest — but it's still a Schedule I drug under FEDERAL law, and the federal line is the one that bites a traveller. Carrying it across a state line, onto federal land like a national park, or through airport screening is a federal offence even between two legal states, and a rental or any federally-assisted home can bar it whatever the state allows. (Federal rescheduling is under active discussion, so this is one to re-check.) 'Legal here, therefore fine' quietly skips the borders, the airport and the owner's own rules.

It varies sharply. Every state has some 'castle doctrine' — no duty to retreat in the home — and many extend it to a lawful occupant, not just the owner: Florida's statute, for one, expressly covers someone 'visiting as an invited guest,' which a sitter is. Thirty-odd states also have 'stand your ground' (no duty to retreat anywhere you may lawfully be); a handful — New York, New Jersey, Massachusetts and others — keep a duty to retreat in public. But all of it turns on facts a court weighs hard afterwards (a reasonable fear of serious harm, lawful presence), and the rules differ state to state, so it's the opposite of something to presume on. The line that holds everywhere: get yourself safe and call 911 first — force is a last resort, never a plan.

There's no national breed ban, and about 22 states actually PREEMPT breed-specific laws — they bar a city from singling out a breed at all. Where a state doesn't, a city or county can: Denver enforced a pit-bull ban for some thirty years before swapping it in 2021 for a breed-restricted permit, while Florida went the other way in 2023, abolishing all local breed bans and ending Miami-Dade's decades-old one. The lesson from both is the same — it's a moving, local question, so check the current ordinance where the house actually is, and ask the owner.

Many states and cities REQUIRE a residential pool to have a safety barrier — typically a fence at least four feet high with a self-closing, self-latching gate — under building codes or pool-safety statutes; Florida, Arizona and California are well-known examples, and the federal safety body recommends the same even where it isn't mandated. Drowning is a leading cause of death for young children, which is why the rules are strict. The legal duty sits with the owner, but a sitter who leaves the gate open or the barrier defeated steps into ordinary-negligence territory if a child gets in and is hurt. Keep the gate shut — it isn't decoration.

Lots of cold-climate cities put the duty to clear the public sidewalk on whoever's in charge of the property, not just the owner. New York City's code names 'every owner, lessee, tenant, occupant or other person having charge,' and gives them about four hours from when the snow stops (overnight excluded) — a house-sitter is squarely an 'occupant having charge.' Miss it and there's a fine, plus slip-and-fall exposure if someone's hurt; Chicago, Boston and many others run similar rules. Ask the owner who normally does it, and where the shovel and salt live.

Money isn't the test. Across legal systems, what makes an arrangement binding is that two people genuinely agreed to it and meant it to count — not whether cash changed hands or anything was signed, and it can be spoken or shown by conduct rather than written down. (Some systems look for something given on each side — here, James's care for Sarah's keys and a roof; others ask only that the promise was seriously meant. A housesit clears either bar.) So 'no cash, nothing signed' is the wrong line everywhere. The subtler, equally universal catch: a purely social favour can fall short of an intended legal commitment, and even a binding deal is painful to prove once memories differ. Agreeing clear terms up front helps with both, which is the point of agreeing them.

In most systems an agreement can be oral or formed by conduct; a signature and a formal document aren't what make it binding. What's hard about an informal deal isn't its validity — it's proving what was actually agreed once memories differ. Writing the terms down doesn't create the obligation; it records it, so nobody has to argue about it later.
