Authorities in Bangkok and across Thailand have noticeably intensified action against illegal short-term condominium rentals, warning that those who continue to rent out units on a daily basis face serious financial penalties under the Hotel Act B.E. 2547 (2004).
Over recent months, local officials, police and the Department of Provincial Administration (DOPA) have joined forces to investigate unlicensed short-term rentals, particularly in Bangkok’s Sukhumvit and Sathorn areas, where online listings remain widespread despite repeated warnings.
The renewed focus on enforcement marks one of the toughest crackdowns in years and is being closely watched by thousands of hosts who use platforms like Airbnb, Booking.com and Agoda Homes to rent out condominium units.
The Law: When a Condo Becomes a ‘Hotel’
Under the Hotel Act, any property offering daily or short-term accommodation for paying guests is considered to be operating as a hotel and therefore requires a hotel licence.
Condominiums are treated as residential under Thai law; absent a hotel licence or a qualifying exemption, using a condo for daily or weekly paid stays is treated as hotel activity and thus unlawful. Most condominiums do not qualify for such a licence because they are classed as residential buildings rather than commercial premises. This means that renting out a condo for less than 30 days at a time is generally illegal unless the building has been officially approved and registered as a hotel or serviced apartment.
Those found in violation face an initial fine of up to THB 20,000, plus THB 10,000 per day for as long as the offence continues. Penalties can extend to facilitators (such as managers or agents) who enable unlicensed operations.
Raids and Rising Enforcement
Authorities have noticeably intensified enforcement in 2025, coordinating inspections with local offices and DOPA in high-traffic districts.
In one high-profile case, officials discovered multiple hidden key boxes containing keys to units offered for daily rent, prompting fines and enforcement actions.
The Bangkok Metropolitan Administration (BMA) has also warned condominium juristic persons that they may be held responsible for allowing illegal short-term activity within their buildings. In some cases, juristic committees have been instructed to remove external key boxes and notify owners who continue to advertise daily rentals.
While large-scale enforcement remains difficult, authorities are now coordinating with booking platforms and local district offices to identify repeat offenders. The message is clear: the days of ignoring the law are coming to an end.
Why the Crackdown Is Happening Now
The short-term rental market has exploded in recent years, driven by the popularity of Airbnb and the return of international travel. Bookings by long-haul travellers surged by nearly 40 % in 2024, according to Airbnb data, as more visitors from Europe, North America and Australia sought flexible, affordable stays.
However, this rapid growth has also drawn the attention of the Thai Hotels Association (THA) and policymakers, who argue that illegal rentals create unfair competition and reduce accountability for guest safety and tax collection. Much of the pressure comes from the hotel lobby pushing for stricter control.
At the same time, local residents have raised concerns about overcrowding, transient visitors and the misuse of common areas in residential buildings. The government’s response is part of a wider effort to regulate the market and restore order in mixed-use areas.
Common Misconceptions Among Hosts
Many property owners believe that using an agent or listing platform somehow shields them from responsibility — it does not. If your property is advertised as a short-term stay, you can be held directly liable under the Hotel Act.
Another misconception is that renting for “29 days” or rotating guests through monthly contracts avoids classification as a hotel. Repeated ’29-day’ contracts may still be viewed as short-term letting if the unit is marketed for daily or weekly stays or shows transient turnover.
Even listing units under different names or accounts will not necessarily prevent enforcement if the evidence points to a continuous pattern of daily or weekly rentals.
What Owners Should Do Now
If you currently rent out your condominium to short-term guests, take the time to review your position carefully.
- Check your building’s bylaws. Many condominium juristic committees explicitly prohibit rentals of less than 30 days. Breaching these rules can lead to legal disputes or restrictions on your ownership rights.
- Review your advertising. If your unit appears online as a ‘daily stay’ or ‘short-term rental,’ you are likely in violation of the Hotel Act unless you hold a licence.
- Keep proper records. Retain lease agreements, guest communications and payment documentation to demonstrate legitimate longer-term rental activity if questioned.
- Seek professional advice. A licensed accountant or legal adviser can confirm whether your operation qualifies for an exemption (for example, if it involves four or fewer rooms within your own residence).
- Stay informed. A draft Accommodation Act remains under review and has not yet been enacted or published in full. Timelines are uncertain; until it passes, existing rules apply.
A Warning for Phuket and Other Tourist Hotspots
Phuket, Pattaya and Chiang Mai are expected to see increased inspection activity during the 2025–26 high season. Officials have indicated inspections will continue through the 2025–26 high season, prioritising Bangkok, Phuket and Chiang Mai.
In Phuket, officials have already begun checking unlicensed properties in popular tourist zones and warning foreign owners of potential prosecution.
As rental revenues rise, so too does government interest in ensuring taxes and compliance are properly managed. The Revenue Department has confirmed that rental income — whether legal or not — remains taxable and must be declared by both Thai and foreign owners.
Protect Your Investment
Thailand’s short-term rental market remains one of the most dynamic in Asia, but the legal landscape is changing fast. Those who continue to operate without a licence risk heavy fines, loss of income, and even criminal charges.
Ensuring your property complies with both tax and licensing regulations is now essential, not optional.
