Renting out a room or apartment by the night or the week in Thailand needs a hotel licence unless the place falls under a small-premises exemption, and many Airbnb-style listings, especially condo units, have neither. The legal duty is on the host, not on you as the guest, but an unlicensed stay can still go wrong for you.
Thailand has no law that names Airbnb. What matters is the Hotel Act B.E. 2547 (2004), which defines what a hotel is, says who needs a licence and sets the penalties. Add the rules of the building you stay in, and you have most of the picture.
This page explains the law from the guest's side, as of October 2026. It is a summary of what the Act and law firms say, not legal advice; if you are a host or an owner, talk to a Thai lawyer.

What the Hotel Act actually says
Section 4 of the Act defines a hotel as accommodation set up as a business to give temporary lodging to travelers or anyone else in return for payment. That is broad enough to cover a single condo unit listed on a booking app. Section 15 then says nobody may run a hotel business without a licence from the registrar.
The penalty is in section 59: up to one year in prison, a fine of up to 20,000 baht, or both, and a further fine of up to 10,000 baht for every day the business keeps running. Those penalties apply to whoever runs the unlicensed hotel. Airbnb's own Thailand page for hosts quotes the same sections and also tells hosts to check the Building Control Act, the Public Health Act and provincial rules.
Law firms describe the practical trigger as renting on a daily or weekly basis. Frank Legal & Tax, writing in 2020, put it plainly: renting out a property by the day or the week without a hotel licence is illegal under section 15.
Where the "30-day rule" comes from
You will often read that stays under 30 days are illegal and stays of 30 days or more are fine. The number 30 does not appear in the Act. What the Act does say, in section 4(2), is that accommodation provided only for a monthly charge or longer is not a hotel.
So the popular "30-day rule" is shorthand for that monthly line. A place rented by the month, on a proper lease, is outside the hotel definition. A place rented by the night, even to the same guest for five weeks, is still being run as short-term accommodation. The way the place is offered and paid for matters more than the length of one booking.
A 31-night booking does not turn a nightly listing into a lease. If the price is quoted per night and the host takes new guests every few days, the place is run like a hotel. A monthly rental means a monthly price and, normally, a written lease.
If you plan to stay a month or more, a real lease is the cleaner route; our guide to renting a condo or house in Thailand covers contracts, deposits and the 2025 rental rules.
The small-premises exemption: 8 rooms and 30 guests
Not every small guesthouse needs a full hotel licence. A ministerial regulation under the Act exempts small places from being treated as hotels. Since Sunday 29 October 2023 the limit is up to 8 rooms and no more than 30 guests; before that it was 4 rooms and 20 guests. The operator must still notify the registrar.
Owners of houses and villas often rely on this exemption. Lawyers disagree about whether it can cover a single unit inside a condominium building, and no court has settled that point in a way we could find. Frank Legal & Tax considers short-term letting of a house or villa safer than letting a condo unit, partly because the known court case involved condos.
Condos: building rules and the Hua Hin case
Condo units carry a second layer of risk. As Frank Legal & Tax points out, the Condominium Act limits commercial activity to the parts of a building set aside for it, such as a shop floor, and many buildings have their own rules on letting. Airbnb's host page itself warns that leases, condominium regulations and community rules can forbid subletting or hosting.
The case most often quoted is from Hua Hin. In May 2018 a court there fined two condo owners 10,000 to 15,000 baht for renting out their units by the day and the week in breach of the Hotel Act. It is not a Supreme Court ruling, and Thai judges are not strictly bound by it, but it showed that the Act is enforced against condo owners. We found no published Supreme Court judgment on daily condo rentals.
Is the guest breaking the law?
Based on the Act and the law-firm commentary we read, no. The licence duty in section 15 and the penalty in section 59 fall on the person operating the accommodation. We found no source saying that a guest commits an offence under the Hotel Act just by staying in an unlicensed rental.
One rule does touch guests in licensed hotels. The manager must record each guest on a registration card at check-in, and section 61 makes it an offence to give false information for that register, with up to one month in prison or a fine of up to 1,000 baht. Give your real details and this never matters. Our page on why Thai hotels ask for your passport explains what happens at the front desk.
What can actually go wrong for you
The practical risks for a guest are about your stay, not about a fine:
- Building staff may stop you. If the condo bans short stays, security can refuse you a key card or ask you to leave, and the host may not answer the phone.
- Last-minute cancellation. A host under pressure from the building or the authorities may cancel, leaving you to find a room in high season.
- No address record for immigration. The owner of the place where you stay is supposed to notify immigration on a TM30 form. Hosts of unlicensed rentals often do not, which can cause trouble if you later extend your stay. Our TM30 guide explains the form and the fix.
- Weaker safety checks. A licensed hotel is inspected; a private flat is not. Look for fire exits yourself; our guide to fire safety in hotels and condos lists what to check.
- Disputes with no local office to turn to. If the place is not as described, your main route is the platform's own refund process. Our page on complaints and refunds in Thailand covers the Thai side.
How to book a short stay with fewer surprises
For a holiday of a few nights or weeks, the simplest legal choice is a licensed hotel, guesthouse or serviced apartment. Hotel booking apps list plenty of them; our round-up of travel apps for Thailand compares the main ones. If you still prefer a private rental:
- Prefer a whole house or villa from a host who says the property holds a hotel licence or has notified the registrar under the small-premises exemption. Ask in writing before you pay.
- For a condo unit, ask the host whether the building allows short stays, and read recent reviews for any mention of trouble at reception.
- If you will deal with immigration during the stay, ask the host to file the TM30 and send you the receipt.
- Keep your booking confirmation and messages until you have left Thailand.
Long-stay visitors have more choice. Once you rent by the month, the Hotel Act no longer applies, and you are a tenant with the rights our condo-rental guide describes. If you are thinking of spending a whole winter, our guide to wintering in Thailand covers visas and where to base yourself, and where to stay in Bangkok compares the main districts. Remember that the visa exemption is 30 days as of October 2026; see our page on the Thai visa exemption before you commit to a long booking.
Frequently asked questions
Is Airbnb illegal in Thailand?
The app itself is not banned. What the Hotel Act forbids is running paid, short-term accommodation without a hotel licence, unless the place is small enough for the 8-room, 30-guest exemption. Many nightly condo listings fall outside both, so they operate in breach of the Act.
Can a tourist be fined for staying in an illegal Airbnb?
We found no source that says so. The licence duty and the penalties in sections 15 and 59 apply to the operator. The real risks for a guest are being turned away by building staff, a cancelled booking and missing TM30 paperwork.
Is it legal to rent a condo for 30 days or more in Thailand?
Accommodation offered only on a monthly basis or longer is outside the Act's definition of a hotel, so a genuine monthly rental on a lease does not need a hotel licence. The building's own rules can still limit letting, so check them.
Does an Airbnb host have to file a TM30 for me?
Yes. The TM30 notification is the duty of the house owner, head of household or person in charge of the place where a foreigner stays, not of the foreigner. If the host does not file it, ask for it, especially before any visit to immigration.
