Most likely to catch you out
- 1'Is unpaid housesitting work?' is live here: Swiss law treats unpaid activity that's normally paid as needing a permit — sharper than a plain grey area, though no border refusal of a sitter is on record.
- 2Covert cameras and recordings are criminal, not just a privacy matter — an undisclosed indoor camera, or a secretly-recorded conversation, can breach Criminal Code Art. 179bis ff.
- 3Dog rules are cantonal — competence courses (Zurich again from 2025), liability insurance and dangerous-breed duties all differ by canton; check the canton of the sit.
- 4Quiet hours and Sunday rest are real, and the official taxed bin-bag system carries fines traced back to the household — follow the local waste and noise rules.
Where you sit changes what matters
The same law lands differently depending on which chair you're in.
- Take the “is this work?” question seriously here — Swiss law explicitly counts unpaid activity that’s normally paid as needing a permit, sharper than most countries’ silence. No Swiss border refusal of a sitter is on record, and EU/EFTA citizens have free movement — but everyone else (UK included since Brexit) should travel as a genuine visitor.
- You need no course or licence to mind a pet — but a lone social animal whose companion dies mid-sit (a guinea pig, a budgie) is a welfare problem to flag, not ignore: Swiss law says they can’t be kept singly.
- Don’t drive until you know the owner’s policy covers you — the drink-drive limit is 0.5g/L, and effectively zero in your first three years, and a named-driver clause can quietly leave you uncovered.
- Check your own cover travels to Switzerland — the GHIC works here for state care but not mountain rescue or repatriation, and a UK home policy may exclude damage to property in your care.
- Disclose and switch off any indoor camera before your sitter arrives — covertly recording a conversation or a private space is a criminal offence here, not just bad manners.
- Confirm your motor policy allows another, occasional driver before leaving the keys — a named-driver or restricted-driver clause can silently void the sitter’s cover.
- Leave written authorisation for emergency vet care with a spending cap — there’s no Swiss rule letting a non-owner approve treatment on their own.
- Where your canton requires dog liability insurance, check it covers a non-owner handler — some cantons (St. Gallen, Solothurn) extend the cover to whoever’s supervising the dog.
The things worth getting right
Where the honest answer is “it depends”, we say so, and point you to the official source.
Immigration & “is sitting work?”
For EU, EEA and Swiss citizens this isn't really a question — free movement covers a stay. For everyone else it's a real grey area, and a slightly sharper one than most: Switzerland's own permit rule says gainful activity “whether paid or unpaid” needs a permit, and treats work normally done for pay as caught even when it's done for free. No Swiss rule names housesitting, and no border refusal of a sitter is on record — but the rule is broad enough that an unpaid sit standing in for paid pet or property care sits inside it. Sharpest for non-EU visitors (UK included since Brexit) at the Schengen border.
Switzerland has never ruled on housesitting, but its position is sharper than a simple silence. The State Secretariat for Migration states that 'all gainful activity — whether paid or unpaid — requires a permit,' and the admission ordinance (OASA Art. 1a) defines gainful employment as work normally done for remuneration even when performed for free. EU/EFTA citizens have free movement and aren't caught. For a non-EU visitor — which since Brexit includes UK nationals — an unpaid sit that stands in for paid pet or property care can, on a strict reading, be unpermitted work. No Swiss border refusal of a housesitter is on record; the exposure is the rule's breadth and an officer's discretion at entry, not a known case.
Cameras, recording & privacy
Covert recording is criminal in Switzerland, not merely a privacy matter. Recording a non-public conversation without everyone's consent is an offence under the Criminal Code (Art. 179bis; Art. 179ter catches a participant who secretly records — the one that bites a sitter or owner mid-conversation), and filming someone's private space without consent is an offence under Art. 179quater — each carrying up to three years, prosecuted on complaint. The data-protection law (revised FADP, in force 2023, overseen by the FDPIC) sits on top, but largely steps aside for a purely private household, where the Criminal Code and the civil right to privacy (Civil Code Art. 28) do the real work. The criminal line protects the home's private areas, not genuinely common or publicly-visible space.
Consent: All parties must consent to recording a private conversation; an indoor camera covering a sitter's living space must be disclosed and, in practice, switched off. Undisclosed recording can be a criminal offence here.
Animals & the law
There is no federal dangerous-dog law — muzzle and leash duties, breed lists, neutering and minimum-age rules are set canton by canton, so a 'listed' breed can carry obligations in one canton that don't exist in the next. Check the rules of the canton you'll be sitting in.
A national dog-owner competence certificate (Sachkundenachweis, SKN) was compulsory from 2008 but abolished at federal level on 1 January 2017. Requirements are now cantonal: Zurich reinstated a mandatory course for all dog owners from June 2025, and several cantons require training for large or listed breeds. A temporary sitter needs no certificate to mind a dog. Switzerland also bans the import of dogs with cropped ears or docked tails.
Driving the owner's car
Swiss motor third-party cover is compulsory and follows the vehicle (Road Traffic Act, SVG), so a permitted sitter driving the owner's car is generally covered toward others. The catch is the policy's 'who may drive' terms: a restricted or named-driver clause can exclude the sitter, and an excluded driver in an at-fault crash can face the insurer's recourse. The homeowner should confirm the policy allows another, occasional driver before handing over the keys.
Drink-drive limit: 0.5g/L blood (0.05%) — stricter than England's 0.8 (0.1g/L (about 0.01%) in the first three years on a licence, and for learner and professional drivers — effectively zero).
The home — licence, not tenancy
A gratuitous housesit is closest to a loan for use (prêt à usage / Gebrauchsleihe, Code of Obligations Art. 305 ff.) — revocable on the agreed terms — not a lease (Art. 253 ff.), so the strong Swiss tenant protections shouldn't attach without rent. There is no clean Swiss rule on whether a very long rent-free occupation could ever drift toward tenant-like protection, so keep a long sit clearly time-limited and rent-free.
Safeguard: An explicit, time-limited licence with no rent.
Courts, claims & “is it worth pursuing?”
A typical housesit dispute — cleaning, vet bills, damage — sits well under CHF 30,000, so it would normally run as a simplified-procedure claim after conciliation. Indicative figures; they swing on the country pair and whether the other side has reachable assets. A foreign claimant suing a Swiss-resident defendant must still attempt conciliation, and can be asked to post security for costs.
No separate small-claims court, but Swiss civil procedure runs a simplified procedure (procédure simplifiée) for money disputes up to CHF 30,000 — a single judge, an active fact-finding role, and no mandatory lawyer (Art. 243 CPC) — most claims must first pass a mandatory conciliation authority (Schlichtungsbehörde / autorité de conciliation) before reaching court (Art. 197 CPC); a claimant may skip conciliation only where the defendant is domiciled abroad (Art. 199 CPC).
At home vs. across a border
A handful of these answers flip entirely depending on whether you’re local or visiting from abroad. The rest bind whoever’s standing there.
Sitting at home (or from the EU/EFTA)
No immigration question — Swiss residents and EU/EFTA visitors come and go freely. Your own licence, your own healthcare. A money dispute with another EU or EFTA country runs on the Lugano Convention — one extra step, but it works.
Visiting from outside the EU/EFTA
The “is this work?” question is live at the Schengen border — and Swiss law explicitly counts unpaid-but-normally-paid work as needing a permit. Your licence is fine unless it isn’t in English, French, German or Italian; healthcare needs the card plus insurance; and a dispute with the UK is the slow one, because the UK isn’t in Lugano. If the sit is unpaid, take your signed agreement with you. It shows what the two of you actually agreed.
The next tier
Tax & money
A short unpaid sit creates no Swiss tax exposure: tax residence needs 30 days with paid work or 90 days without, and non-residents are taxed only on Swiss-source income, which an unpaid sit doesn't produce. A like-for-like accommodation swap and reimbursed expenses aren't income; cash for services could be. General principle — Switzerland has no housesitting-specific tax rule. Self-employment route: AHV/AVS registration.
Emergencies & healthcare
Emergency care is given to anyone. EU/EEA visitors use their EHIC, and — unusually for a non-EU country — UK visitors can use the GHIC, which works in Switzerland under the UK–Switzerland social-security convention. Both cover state, medically-necessary treatment only: not repatriation, not private care, and not mountain rescue. Rega, the air-rescue service (dial 1414), is a private foundation, and a non-patron without travel insurance can be billed thousands for a helicopter. Carry travel insurance alongside the card, never instead of it.
Guests & registration
A short housesit triggers no personal registration — you register with the commune only if you stay beyond about 90 days, within 14 days of arrival. And a free private host carries no federal duty to report a foreign guest: the reporting duty (Foreign Nationals and Integration Act, Art. 16) falls on those who accommodate foreign nationals for commercial gain — hotels and paid lets, not an unpaid sit. A few cantons word notification duties for paid guests more broadly (Geneva, for one), so 'free, under 90 days' is the clean position and 'check the canton' the honest caveat.
Your data & privacy
Privacy law: Swiss Criminal Code Art. 179bis ff. + revised Data Protection Act (revFADP) / FDPIC. You have access and erasure rights over your own data.
Tall tales, checked
Sorted into myth, part true and true. The ones particular to this country each carry a source; the last two are about how agreements work everywhere.
“In Switzerland you're not allowed to flush the toilet after 10pm.”
James is a few days into minding Sarah's flat in Bern when a neighbour mentions, half-seriously, that flushing after ten at night is against the rules. He spends a baffled evening wondering whether Swiss plumbing really comes with a curfew. It doesn't. There is no law anywhere in Switzerland banning a night-time flush — what's real is the quieter idea underneath it: after about ten, you keep the noise down.
Show the legal detailHide the legal detail
No Swiss statute bans flushing at night, and fact-checkers have rated the claim false. What is real is the night-quiet (Nachtruhe, roughly 10pm–6am) set by cantonal and municipal rules and by a building's own house rules (Hausordnung), plus a tenant's general duty of consideration under the Code of Obligations (Art. 257f). A blanket flush ban would fail the basic test of being proportionate, and the Swiss Tenants' Association says it would not stand up. So use the bathroom normally — just don't run a noisy 11pm load of laundry.
PolitiFact · the Swiss toilet-flushing claim, rated false ↗“It's illegal to keep just one guinea pig in Switzerland — sociable pets have to come in pairs.”
Sarah's two guinea pigs, Rösti and Fondue, are a bonded pair, and she's left James careful notes on both. Halfway through the sit the older one dies. James assumes the survivor will be fine alone until Sarah is home — but in Switzerland a lone guinea pig isn't just a sad sight, it's a welfare problem the law actually names. He messages Sarah, and they sort out company rather than leave it by itself.

Article 13 of the Animal Welfare Ordinance (TSchV) requires animals of socially-living species to have appropriate contact with their own kind. Guinea pigs, mice, gerbils, degus and ferrets 'may in no case be kept singly,' and the rule reaches budgerigars, canaries, parrots and even goldfish; a person does not count as a substitute. The cantonal veterinary office enforces it as a welfare matter, and the city of Zurich even runs a guinea-pig 'companion' service for exactly the bereaved-survivor case. For a sitter the duty is real and immediate: a social pet that loses its partner mid-sit should not simply be left alone — flag it to the owner and sort company. (Hamsters are the exception — they're solitary by nature.)
Tier im Recht · single-keeping of social small animals breaches Art. 13 TSchV ↗“Use the wrong bin bag in Switzerland and the rubbish police will dig through it, find your name, and fine you.”
James has a week's rubbish to clear and, not finding any ordinary black sacks under Sarah's sink, uses a supermarket carrier instead. What he doesn't know is that in most Swiss communes household waste only goes out in an official, paid-for bag — and that the ones turning up wrong sometimes get opened. An old envelope with the address on it is all it takes to trace a bag back to the house.
Show the legal detailHide the legal detail
Most Swiss communes run a pay-per-bag system (the Sackgebühr — Zurich's Züri-Sack, Basel's blue bag), where the official taxed bag is the only legal way to put out general waste; unofficial bags aren't collected. Cities really do employ waste inspectors who open wrongly-disposed bags, look for a name on a letter or bill, and fine the person — in Basel an illegally dumped bag is fined CHF 150 (17–35 litres) or CHF 250 (35–110 litres), with prosecution above that, and a proper bag put out at the wrong time is CHF 50. The fine lands on whoever is traced, which on a sit means the household. So use the owner's commune bags and follow the recycling days.
SWI swissinfo.ch · on patrol with the Swiss 'rubbish police' ↗“Switzerland makes you take a course before you're allowed to own a dog.”
James mentions to a Swiss friend that he's minding Sarah's labrador for a fortnight, and gets asked whether he had to do 'the dog course.' He didn't — and he doesn't need one. But the question isn't daft: Switzerland really did require one once, still does in places, and which answer is right depends entirely on the canton.
Show the legal detailHide the legal detail
A national dog-owner course (the Sachkundenachweis, SKN) was compulsory across Switzerland from 2008 — but it was abolished at federal level on 1 January 2017. Since then it's a cantonal patchwork: Zurich reinstated a mandatory course for all dog owners from June 2025, and several cantons require training for large or listed 'dangerous' breeds. Either way it's the owner's obligation, never a temporary sitter's — James needs no course or licence to mind Sarah's dog. (The dog is registered and taxed by its owner's commune, too — also not the sitter's concern.)
The Local · Zurich reinstates mandatory dog classes from June 2025 ↗“On a Swiss Sunday you can't mow the lawn, run the washing machine, or take bottles to the recycling.”
It's a sunny Sunday, and James — wanting to leave Sarah's place spotless — lines up a wash, eyes the overgrown lawn, and gathers a week of wine bottles for the bottle bank. A neighbour's raised eyebrow stops him. None of it is quite a police matter, but a Swiss Sunday really is meant to be quiet, and some of it is genuinely enforced.
Show the legal detailHide the legal detail
Sunday and night quiet rest on municipal ordinances, a building's house rules (Hausordnung), and the tenant's duty of consideration (Code of Obligations Art. 257f) — not one national statute. In practice many buildings bar noisy appliances on Sundays and late at night, and a lot of communes specifically forbid dropping glass and aluminium into public recycling banks on Sundays and holidays (the clatter), with fines for it. Lawn-mowing falls under the same Sunday-quiet expectation. The usual consequence is a neighbour complaint and a landlord warning rather than a fine — but the bottle-bank rule can be a real penalty, and it lands on the household. So save the wash, the mower and the bottles for a weekday.
The Local · six things you shouldn't do on a Sunday in Switzerland ↗“On a winter sit, clearing snow and ice off the path can fall to the sitter — and a slip can be the sitter's liability.”
James is on a winter sit in a village near Lucerne when it snows hard overnight. He assumes a snowy path is the absent owner's problem and leaves it. By mid-morning the postwoman has slipped on the icy walk to the door — and in Switzerland the duty to clear and grit it doesn't simply wait for the owner to come home; it's routinely the job of whoever's living there.
Show the legal detailHide the legal detail
Swiss property and tenancy practice imposes a duty to clear and grit paths (the Schneeräumungs- und Streupflicht). The owner carries it in principle, but it's routinely delegated to the occupant — a tenant, a caretaker, or a sitter living in the home — and whoever holds it can be liable in damages if someone is hurt on an un-cleared path (with some allowance for the pedestrian's own care). It dovetails with the insurance picture: if a guest slips on the owner's icy steps, it's the owner's liability insurance that answers — which is exactly why a clear word about who clears the snow belongs in a winter sit's agreement. (The Code of Obligations, Art. 58, also makes a building's owner liable for damage caused by poor upkeep.)
homegate.ch · snow removal — who is responsible? ↗“It's unpaid and nothing's in writing, so there's no real agreement — and nothing's enforceable.”
James agrees to mind Sarah's flat and her two cats for a fortnight while she's away — no money, nothing signed, just a few texts and a chat at the door. Sarah comes home, blames him for a scratched table, and insists there was never a 'real' agreement to break. But there was: each of them gave the other something they wanted — James's care in return for Sarah's keys and a roof over his head — and that swap is exactly what the law treats as a deal, cash or no cash. What Sarah would struggle to pin down isn't the missing money; it's what the two of them actually agreed in the first place.
Show the legal detailHide the legal detail
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.
“A handshake or a few texts can't be a real contract — it has to be a formal signed document.”
Sarah and James set the whole sit up over WhatsApp — the dates, the dog's walks, who covers the heating — and because nothing's signed, James assumes none of it really counts. It does. A deal struck by text, or with a nod at the door, can bind just as tightly as a printed page. The paperwork was never the magic; it's the receipt, so neither of them can later 'remember' it differently.
Show the legal detailHide the legal detail
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.
