Can You Sublet or Airbnb a Rented Condo in Bangkok?

Most of what’s written about Airbnb and short-term rentals in Bangkok is aimed at condo owners deciding whether to list their own unit. This guide is for a different reader: someone who is themselves a tenant, renting a condo from a landlord, and wondering whether they can sublet a room, hand the whole unit to someone else while they travel, or list it on Airbnb for extra income. The legal exposure is different (and in some ways higher) than it is for an owner, because a tenant who sublets is answerable to both their own landlord and to the building’s rules, on top of the same national laws that apply to everyone. This complements rental contracts and deposits for the lease itself and monthly and short-term rentals for how short-stay letting works from the other side of the transaction.

Why this is a tenant’s problem, not just an owner’s

An owner who lists their own condo on Airbnb risks trouble with the Hotel Act and their building’s juristic person. A tenant who sublets faces both of those risks plus a third one entirely of their own: breaching their own lease with their own landlord. Losing a dispute with a building’s juristic person is one thing; losing your home because your landlord terminates your lease for an unauthorised sublet, and potentially keeps your deposit for breach of contract, is a different order of consequence. Read the rest of this guide with that stacked exposure in mind: the legal risk and the personal risk to your own tenancy are separate problems that both need to be solved before you sublet anything.

What your own lease almost certainly says

Standard Bangkok residential leases restrict subletting, and most prohibit it outright without the landlord’s prior written consent: this is covered as part of the standard contract terms in rental contracts and deposits. A sublease clause in a Thai lease typically does one of three things: bans subletting entirely, allows it only with the landlord’s written consent given case by case, or is silent on the question, which in practice is usually read against the tenant rather than for them, since the landlord chose who they wanted to rent to and didn’t sign up for a stranger living there instead. If your contract doesn’t mention subletting at all, don’t treat silence as permission: ask your landlord directly and get any agreement in writing before you act on it.

Subletting without permission where your lease prohibits it is a straightforward breach of contract, independent of anything to do with hotels or condo bylaws. A landlord who discovers an unauthorised subtenant can typically terminate the lease, and depending on your contract’s wording and the circumstances, may have grounds to withhold some or all of your deposit for breach. This is true even if the sublet itself would otherwise be perfectly legal: a fully above-board, 12-month sublease to a single quiet tenant is still a lease breach if your own contract forbids it and you didn’t ask.

The Hotel Act: the 30-day line that matters most

Separately from your own lease, Thai law draws a hard line between residential letting and operating a hotel. Under the Hotel Act, letting out accommodation for stays of fewer than 30 days falls within the legal definition of a hotel business, which requires a hotel licence, something an ordinary residential condo unit essentially never has and normally cannot obtain. This is the line that makes daily and weekly Airbnb-style listings of a condo unit illegal in the way most people mean when they say “Airbnb is illegal in Thailand”: it isn’t Airbnb specifically that’s banned, it’s operating unlicensed short-stay accommodation, and Airbnb happens to be the most common platform used to do it.

The distinction that matters for a tenant subletting: a sublet for 30 days or more to a single tenant, done with your landlord’s consent and disclosed properly, sits outside the Hotel Act’s definition of a hotel altogether: it’s simply a residential sublease. A sublet for stays shorter than that, whether booked through Airbnb, Booking.com, a messaging app, or word of mouth, falls inside the Hotel Act’s scope regardless of the platform, and carries the same legal exposure as if a condo owner had done it themselves.

What enforcement actually looks like

Enforcement against unlicensed short-term letting in condo buildings has picked up noticeably, driven partly by complaints from other residents and partly by direct government attention on the practice in buildings with a visible pattern of daily turnover. The Hotel Act’s own penalty provisions attach criminal liability to operating without a licence, and commentary on the Act describes a combination of a fine and potential imprisonment, with a further daily fine for as long as the unlicensed operation continues: treat the exact figures as indicative and subject to the specific facts of a case rather than a fixed number, and note that the person named as the operator (which could be the tenant doing the subletting, not just the unit’s owner) is the one exposed. This guide won’t set out how to run short-term listings without being noticed: that’s a legal risk with real consequences, not a grey area to game, and it isn’t something we advise on.

Common myths worth clearing up

• “It’s fine if I only sublet to friends, not strangers off Airbnb.” The Hotel Act’s 30-day threshold looks at the length of stay, not how you found the guest or whether money changed hands through a booking platform. A short stay is a short stay whether it was arranged on Airbnb or through a group chat.
• “My landlord won’t find out if it’s just occasional.” Buildings with any kind of staffed entrance, key-card system, or active juristic office tend to notice a rotating pattern of guests and luggage fairly quickly, and a neighbour’s complaint is often what triggers a juristic-person investigation in the first place. Occasional isn’t the same as unnoticed.
• “A ‘long-term’ Airbnb booking of 28 or 29 days gets around the rule.” It doesn’t: the Hotel Act’s threshold is about actual stays under 30 days, and structuring a booking to sit just under that line while functioning as short-term letting doesn’t change what it actually is.
• “If the juristic person hasn’t adopted a formal rule against it, it must be allowed.” Even without a specific building bylaw, the Hotel Act’s licensing requirement applies at the national level regardless of what a given building’s rules do or don’t say: the building rule is an additional layer of risk, not the only one.

The juristic person and building bylaws

Even where the Hotel Act itself is satisfied (because a sublet genuinely runs 30 days or more), a condo building’s own house rules can independently restrict or ban subletting and guest turnover. Thailand’s Condominium Act gives a building’s juristic person authority to set and enforce rules for common areas and resident conduct, and a great many Bangkok condominium buildings have adopted rules explicitly prohibiting short-term guest turnover, sometimes going further to restrict subletting generally, as part of protecting residents’ security and quiet enjoyment. These building-level rules operate independently of your lease and of national law: a sublet that would otherwise be legal under the Hotel Act can still put you in breach of the building’s own regulations if the juristic person has adopted a restriction, and juristic offices increasingly monitor for the pattern of frequent new faces and rolling suitcases that a short-stay operation produces.

If you’re considering any kind of sublet, checking the building’s own house rules (not just your lease and not just national law) is a third, separate check that’s easy to skip and shouldn’t be.

The three checks, side by side

All three are independent: passing one doesn’t clear the others, and a tenant needs all three to actually be in the clear before subletting anything.

Subletting for 30 days or more: still not automatic

Even a longer-term sublet that clears the Hotel Act threshold isn’t automatically fine just because it avoids the hotel-licensing problem. You still need your own landlord’s consent under your lease, and the building’s bylaws still apply to whoever is actually living there: a subtenant is subject to the same rules on noise, guests, and common-area use as you are, and the juristic person and your landlord will generally hold you responsible for a subtenant’s conduct. A landlord asked to approve a 30-day-plus sublet is more likely to agree if you can show the arrangement is genuinely residential (a single subtenant, a real term, a written sub-agreement) rather than a rotating cast of short-stay guests dressed up as a “monthly” booking to sidestep the Hotel Act’s threshold on paper while functioning as short-term letting in practice.

TM30 and immigration reporting if you sublet to a foreigner

If you sublet to a foreign tenant, the same residence-reporting duty that applies to any landlord applies here: someone occupying or managing the property is generally required to notify immigration of a foreign occupant, typically within 24 hours of arrival. As the person actually in control of who’s staying in the unit, this responsibility can land on you as the subletting tenant in practice, on top of whatever your own landlord’s obligations are for you. Getting this wrong doesn’t just risk you personally: it can create problems for your subtenant’s own visa extensions and 90-day reporting. See TM30 for renters for how this duty actually works and who is legally on the hook for it.

If you want to sublet legitimately

1. Re-read your lease’s sublease clause first. If subletting is banned outright, get your landlord’s written agreement to vary that term before doing anything else: don’t proceed on a verbal “should be fine.”
2. Check the building’s house rules, not just your lease, ideally by asking the juristic office directly or reviewing the rules pack you should have received at move-in.
3. Structure any sublet at 30 days or more, with a real sub-agreement in writing, to stay outside the Hotel Act’s licensing requirement.
4. Handle TM30 and residence reporting properly for any foreign subtenant, and make sure your own landlord isn’t left unaware of who’s living in their property.
5. Get everything in writing (your landlord’s consent, the sub-agreement’s term and rent, and confirmation the building has no objection) so you’re not relying on memory if a dispute arises later.
6. If in doubt, ask before you list anything. A short conversation with your landlord and the juristic office costs you little; unwinding an unauthorised sublet, a terminated lease, or a Hotel Act complaint costs considerably more.

If you’re thinking about Airbnb specifically

Listing a condo you rent (rather than own) on a short-stay platform stacks every risk above at once: a probable lease breach with your own landlord, a Hotel Act exposure if any booking runs under 30 days, and a near-certain building-bylaws conflict if the juristic person has a short-term rental ban, which is now common. There is no version of this that’s low-risk for a tenant, and unlike an owner, you don’t even have the (still legally exposed) fallback argument of “it’s my own property.” If the appeal is the income rather than a specific short travel need, monthly and short-term rentals sets out how the legitimate monthly-rental market actually works, which is a materially safer way to generate income from spare capacity in a unit you control under your own lease terms.

A note on this guide

This is general information about how subletting and short-term letting rules apply to a tenant in Bangkok, not legal advice, and nothing here should be read as guidance on how to avoid detection while operating outside these rules: that isn’t a service this guide provides. The Hotel Act’s 30-day threshold and the Condominium Act’s provisions on juristic-person authority are established law, but how a specific building’s bylaws are worded, how actively a given juristic person enforces them, and how a specific landlord’s lease treats subletting all vary. Verify your own lease terms, your building’s house rules, and the current legal position with a Thai lawyer before acting, particularly if you’re considering anything that generates rental income from a unit you don’t own.

Common questions

Can I sublet part of my condo, like a spare room, to a friend?

Only if your lease allows it or your landlord consents in writing: a spare-room arrangement is still a sublet in the eyes of most standard leases, even if no formal booking platform is involved. Ask first rather than assuming an informal, unpaid, or short arrangement is automatically fine.

Is it legal if I only list my condo on Airbnb while I’m away for a couple of weeks?

The short answer is generally no if the guest’s stay is under 30 days, regardless of how occasional the listing is: the Hotel Act’s threshold applies to the length of the individual stay, not to how often or how casually you list the unit. Occasional and well-intentioned isn’t a legal exception.

What if my landlord says it’s fine to sublet on Airbnb?

Your landlord’s consent solves the lease-breach problem between you and them, but it doesn’t solve the Hotel Act exposure for stays under 30 days, and it doesn’t override the building’s own juristic-person rules if they prohibit short-term letting. All three checks are independent of each other.

Can the juristic person fine me directly, or does it have to go through my landlord?

A juristic person generally enforces building rules against the unit and, through it, the registered owner, meaning your landlord is typically the one formally on the hook to the building, even though you’re the one who actually sublet. In practice this usually means your landlord passes any consequence straight back to you through your lease, which is exactly why unauthorised subletting is such a direct risk to your own tenancy.

Does a 30-day-plus sublet need to be registered anywhere?

There’s no separate national registration requirement specific to subletting itself, but your landlord’s consent should be documented in writing, and any foreign subtenant still needs the standard residence-reporting steps handled correctly. Check whether your building’s juristic office wants written notice of any subtenant, since many now ask for this as a condition of allowing longer-term sublets at all.

If I get caught subletting short-term, who actually gets in trouble: me or my landlord?

Both can be exposed, in different ways. The Hotel Act’s licensing requirement targets whoever is operating the unlicensed accommodation, which in a tenant-sublet scenario is realistically you, while your landlord separately faces a lease dispute (and possibly their own exposure to the building) for having a tenant who did this without consent. Assuming the risk sits only with the property’s owner is a mistake specific to the tenant-sublet situation this guide covers.

Is it different if I sublet through a company that specialises in managing short-term rentals?

No: using a management company to handle bookings, cleaning, and guest communication doesn’t change the underlying legal position. If the stays are under 30 days, the accommodation still needs a hotel licence regardless of who is operating the calendar, and your own lease’s sublease restrictions still apply to you as the tenant who brought the company in.
