Can Foreigners Rent Out a Condo in Thailand? A Guide

"Can foreigners rent out a condo in Thailand?" is the most common question we get from owners overseas — and the answer is yes. It has been ever since foreign ownership of Thai condos existed. But the operational picture that follows — building rules, TM30, taxes, the practical setup if you're not in Bangkok — is the same picture we walk every owner through, foreign or Thai resident.

This guide answers the legal question first, then the operational one. Limited to Bangkok condos — the case we actually operate in.

The short answer

Yes. A foreigner who legally owns a Bangkok condominium unit can rent it out. Thai law gives the registered owner the right to lease, regardless of nationality. The licence to own and the right to let go together.

What changes the picture is how short the let is. Stays of 30 nights or more sit cleanly inside the law and inside almost every condo by-law. Stays under 30 nights — daily Airbnb-style lets — push you into a regulatory grey zone where the Hotel Act, the Condominium Act and your building's juristic person all have something to say. Almost every practical question owners have routes back to that one threshold.

Foreign ownership and the right to lease

The Condominium Act allows foreigners to own up to 49% of a building's total floor area as freehold units, the so-called "foreign quota." The unit's title deed is registered in the foreign owner's name at the Land Department, and that registration is what gives the right to use, lease, transfer or sell the unit.

There is no separate licence to rent it out. The right is inherent to the title. You do not need to be physically in Thailand to do it — most of the foreign owners we work with are not. You do not need a Thai partner or company. You need three things: the title, a Thai bank account (or, in practice, a manager who can hold and remit funds), and a strategy for how long your typical stay will be.

Thai resident owners have the same right to lease, with simpler banking — domestic transfers, no repatriation step, and direct access to the building during the working day. The rules from here on apply to every owner regardless of nationality.

Where the line falls: the 30-night rule

Thailand's Hotel Act (2004) requires a hotel licence for any business that "provides temporary accommodation for travellers" — and "temporary" is defined as stays of less than 30 days. A condo unit cannot get a hotel licence. So renting a unit out for stays under 30 nights, as a commercial activity, is technically an offence under the Hotel Act.

The 30-night threshold is the legal line, and it is also the line most condo by-laws use. Stays of 30 nights or more are broadly accepted. Stays of 1–29 nights are where the legal grey zone, the building enforcement, and the platform risk all live.

This is why we — and most operators who run clean — focus on mid-term rentals: 1 month or longer. The legal posture is unambiguous, building rules are satisfied, and the demand pool (relocations, longer business trips, the Destination Thailand Visa, expat resets between leases) is large enough to keep occupancy strong. The full picture of the 30-night rule, including how enforcement actually works, is in our Airbnb legality in Thailand post.

What your condo's juristic person can require

Above the law sits your building's own rule book. Every Thai condominium is run by a juristic person — the legal body of the unit owners, with a manager who enforces the day-to-day rules. Common requirements that affect rentals:

• Minimum stay. Many Bangkok buildings explicitly set a 1-month or 3-month minimum in their by-laws. Some go further and require a 6- or 12-month lease.
• Lease registration. Most juristics ask to see the signed lease agreement and to register the tenant before they will issue access cards or keys.
• Guest registration on arrival. Buildings increasingly require face-scan registration, ID verification or in-person sign-in at check-in. This is one of the operational details that catches new landlords.
• Common-area access. Some buildings restrict pool or gym use to long-stay tenants only, or charge per access card.

None of this prevents you from renting; it shapes how. We operate to the specific rules of every building we manage — for some, the registration is a five-minute job, for others it requires a juristic appointment scheduled before the guest arrives.

TM30: the landlord's filing obligation

Separate from the Hotel Act, Thai immigration law requires that every time a non-Thai stays at a property — for any length, including one night — the property owner notifies the local immigration office within 24 hours. This is the TM30 filing, and it applies to landlords as well as hotels.

For mid-term and long-term rentals, that means a single filing at the start of each lease. For shorter stays, a filing per guest, per booking. Failing to file carries a fine and, more importantly, complicates your foreign tenant's visa or extension paperwork when they need it.

TM30 is filed online and the process is routine once you know it. We file it on every booking on our owners' behalf — automatically — so the obligation never lands back on the owner.

Income tax on rental income

Rental income earned in Thailand is taxable in Thailand, regardless of the owner's nationality. The picture splits along tax residence, not passport:

• Thai tax residents (anyone in Thailand 180+ days a year, Thai or foreign) declare worldwide and Thai-source rental income on a Thai personal return, with deductible expenses (management fee, repairs, depreciation, CAM, etc.) netted off.
• Non-resident foreign owners (in Thailand fewer than 180 days a year) declare only Thai-source rental income on a Thai return. The same expense deductions apply.
• A 15% withholding tax can apply at source when a corporate tenant pays rent direct — relevant for company-let scenarios, less often for individual guests.
• Double-taxation treaties between Thailand and most European, UK, US, Singaporean and Australian jurisdictions usually mean tax paid in Thailand is creditable against tax owed at home. Specifics depend on your residence — talk to a tax adviser in your own country.

We do not file owner tax returns, and you should not expect a property manager to do that. But we provide an itemised monthly statement and an annual summary that your accountant can plug directly into the return.

The practical setup

The setup is broadly the same whether you live abroad or in Bangkok — only the banking and the day-to-day involvement differ.

1. A signed management agreement with a Thai-based operator who can run the unit, file TM30, coordinate the juristic, handle guests and reconcile money. (For a clear picture of what that looks like step by step, see how we onboard.)
2. Banking. Owners abroad either keep net rental income in a Thai bank account or have it remitted to an overseas account. Thai-resident owners just receive it locally. Either way, every transfer is reconciled in the monthly statement.
3. An accountant, in your country of tax residence (or in Thailand if you're resident here), who handles the annual return.
4. An income projection before you start, so you have a benchmark to judge actual performance against. Our income estimator gives you that, based on real curated data for Bangkok buildings rather than platform averages.

The piece most owners get wrong is the first one: they pick the cheapest manager, lose Superhost status or rental income through poor operations, and switch a year later. Choosing well at the start is the lever that matters most.

How Maison Siam handles it

Maison Siam is the rental asset management partner for Bangkok properties, whether the owner lives abroad or in Bangkok: an in-house team for housekeeping and maintenance, properties run under our Superhost account, monthly itemised reporting, and the compliance plumbing — TM30, juristic person registration, lease drafting — handled for every booking.

We focus on mid-term rentals (1 month and up) precisely because they sit cleanly inside Thai law and inside almost every condo by-law. Our fee is a percentage of net rental income, so our performance and yours move together.

If you own a Bangkok condo — whether you're here or overseas — and are weighing whether to rent it out, run an estimate for your specific unit. If you would like to talk through the legal and operational specifics, speak to our team — we respond within two business days.
