Quick answer: two separate rules govern this and both have to be satisfied. Thai law treats accommodation let for under 30 days as hotel business, licensed at building level, so nightly listings require a hotel-licensed building. Separately, the condominium’s own registered regulations may restrict letting whatever the law permits. Long-term tenancies of 30 days or more sit outside the hotel definition and are straightforward. Pillar reading: the rental yield guide and the short-stay compliance guide.
Letting a unit legally is not a matter of writing a careful listing. It is a matter of matching your intended rental model to the building’s licence class, its registered regulations and its operating setup, and all three of those are decided before you own the unit rather than after.
The two rules, kept apart
Most confusion in this area comes from collapsing two different questions into one.
The first is statutory. The Hotel Act treats the provision of accommodation for stays under 30 days, for payment, as hotel business, and hotel business requires a licence. That licence attaches to premises, not to people, which is why an individual owner in a residential tower cannot obtain one for a single unit and why “I registered a company” does not solve it.
The second is contractual and private. The condominium’s registered regulations bind every owner, and they may impose a minimum letting period, require tenants to be registered with the juristic person, restrict subletting or prohibit commercial use of the common areas. These rules apply whatever the licence position, and a building with a hotel licence can still have regulations that constrain what individual owners may do.
You need a yes from both. A yes from one is the situation that produces most of the enforcement problems on the island.
Buildings that support nightly letting
| What to request | Why it matters |
|---|---|
| Copy of the hotel licence certificate | The document, not an assurance that one exists |
| Confirmation the licence scope covers your unit | Licences often cover one tower or phase, not a whole development |
| Rental provisions in the registered regulations | The private rules that sit alongside the licence |
| The check-in and guest registration process | Evidence the building actually operates as licensed |
| The operator agreement and its fee stack | What you will net, and who carries the compliance duty |
A properly licensed building looks like a hotel in its operations as well as its paperwork: there is a desk, guests are registered, and somebody is accountable for it. Where the licence exists on paper and nothing in the lobby reflects it, ask harder questions, because the arrangement you are relying on may be less settled than the certificate suggests.
Get all of this before you buy if short-stay revenue is part of your case for the purchase. Licence status is one of the few characteristics of a unit that cannot be fixed afterwards by spending money.
Residential-only buildings
If the building is residential and unlicensed, nightly letting is not a grey area to be managed. It is unlawful, and the exposure is practical rather than theoretical.
The usual sequence is a complaint from a resident, a warning from the juristic person, a fine under the building’s own fine schedule, an instruction to remove guests mid-stay, and delisting by the platform once a report is filed. Guests caught in that sequence leave reviews that persist long after the listing is restored elsewhere, and an owner who has been through it usually finds the second attempt harder than the first.
Enforcement is uneven across the island, which is what tempts owners into it. Uneven is not the same as absent, and the pattern in mixed-use buildings is that tolerance falls as the proportion of nightly guests rises, so the model gets riskier precisely as it gets more profitable.
The long-term path
Tenancies of 30 days or more are the ordinary way to let a condominium here and they carry none of the hotel licensing problem.
The trade is obvious in the numbers: lower gross revenue, materially lower costs, and far steadier occupancy. Management runs at roughly 8 to 15% of rent rather than the 18 to 25% of revenue typical of short-stay operation, there is no linen, no cleaning cycle between guests and no daily communication, and a good tenant on a 12-month lease removes the vacancy risk that dominates a nightly model.
Three points still need checking in the regulations. Any minimum term the building imposes, which is sometimes 6 months rather than 30 days. Tenant registration requirements, since the juristic person will usually want the occupant on file. And subletting restrictions, which matter if your tenant is a company housing staff.
For many foreign owners this is the better model regardless of the licence question, particularly for units away from the tourist strips where nightly demand is thin and seasonal anyway.
Tax, and the part of “legally” that is not about licences
Compliance has a second half that owners think about far less than the licence, and it is the one that reaches you rather than the building.
Rental income from a Thai property is Thai-source income and is taxable here, whether you are resident or not and whether the money is paid into a Thai account or an offshore one. The rate depends on how long you are in Thailand. Under 180 days a year you are a non-resident, tax is withheld at source at 15%, and that is generally final with no Thai return to file. At 180 days or more you are a Thai tax resident and file on the progressive personal income tax scale. Where the unit is held through a company, the corporate rules apply instead.
Short-stay use also brings the land and building tax into a different band than residential occupation does, at a materially higher rate, which is one more reason to establish permitted use before building a nightly model. And your own country may tax the same income, with relief depending on a double taxation agreement, so the reporting is rarely confined to one jurisdiction.
None of this is difficult, and all of it is easier arranged in advance. Engage an accountant who works with foreign owners before the first booking, and keep the operator’s statements in a form that supports a filing rather than a spreadsheet reconstruction 18 months later.
What “verified” actually looks like
Owners often say the rental position was checked when what happened was that somebody said it was fine. The difference is a small file, and it is worth assembling in this order.
A copy of the hotel licence certificate, with the premises it names read against the building you are buying in. The registered condominium regulations, translated, with the rental clauses marked. A written answer from the juristic person confirming that your unit sits inside the licence scope and that owner letting is permitted. The last 2 years of AGM and committee minutes. The operator agreement with its fee stack set out in full. And a short letter from your own lawyer confirming what all of that adds up to.
That file costs a modest amount to assemble and it does two things. It tells you whether the business you are underwriting exists, before you pay for it. And if the building’s politics change in 3 years, it is the record of what you were entitled to do when you bought, which is a considerably better position than recollection.
Buyer scenarios
The long-term landlord. Buy where the regulations permit 6 to 12 month tenancies and furnish for a resident rather than a holidaymaker: a desk, storage, a proper kitchen. Income is lower and more predictable, the unit takes less wear, and the compliance question effectively disappears.
The hybrid owner. You want personal use plus income. This works in a licensed building with a competent operator: you block your weeks, the operator runs the rest, and you accept that the weeks you take are the weeks that were worth most. Model the yield on the availability you will actually release, not the full year. See the lifestyle plus income model.
The owner in an unlicensed building. Convert to 30-day minimum letting and rebuild the model around monthly tenants rather than trying to manage the risk. The revenue drop is real and smaller than most owners expect once the short-stay cost stack comes off, and it converts an enforcement exposure into an ordinary tenancy.
The buyer still choosing. Make licence status a filter rather than a discovery. Two otherwise identical units in adjacent buildings can support entirely different businesses, and the difference is worth more than any feature you are comparing on the floor plan.
Choosing between the two models on the numbers
Once the licence question is settled, the choice between nightly and monthly letting is an ordinary business decision, and it is decided by the unit rather than by preference.
Nightly letting rewards location, size and the quality of the operator. A compact unit within walking distance of a beach that guests actually book, run by somebody with real distribution, can outperform a monthly tenancy by a wide margin in the high season and then spend the wet months half empty. The revenue is seasonal, the costs are not, and the model lives or dies on blended annual occupancy rather than on the daily rate the brochure quotes.
Monthly letting rewards the opposite characteristics: a practical layout, parking, proximity to schools, hospitals or an office rather than to a beach, and a building that residents want to live in year-round. Income is lower and it arrives every month, including September.
The comparison that matters is annual net against annual net, on trailing data from the same building, with the operator’s full fee stack applied and a realistic vacancy assumption on the nightly side. Run it before you furnish, because the two models want different furniture, and a unit fitted out for holidaymakers reads as impractical to a long-term tenant.
The juristic office is the gatekeeper
| Signal | What it tells you |
|---|---|
| A written short-stay policy on file | Predictable, whichever way it goes |
| A guest registration procedure in use | Building is genuinely operator-ready |
| A fine schedule in the regulations | You can quantify the exposure before you take it |
| Short-stay complaints recurring in AGM minutes | Political risk is rising, rules may tighten |
| No policy and no minutes | The rules will be made after your first complaint |
Read the last 2 years of AGM and committee minutes before you commit to a rental strategy. Buildings that have fined owners before tend to do it again, and buildings where owners are actively arguing about nightly guests are buildings where the regulations are likely to change against you at the next general meeting. That is a document request, not a judgement call, and any juristic office should be able to produce it.
Deep dive: what the juristic office does.
Red flags before you sign a management contract
| Red flag | What it usually means | What to check |
|---|---|---|
| ”Everyone here does it, nobody minds” | No licence, and tolerance you do not control | The certificate, in writing |
| Operator quotes gross yield only | Costs are being left out of your comparison | Net after the full fee stack, on trailing data |
| Licence covers “the development” | Scope may exclude your tower or phase | Which buildings the licence names |
| No guest registration in practice | Operations do not match the paperwork | Observe a check-in, ask who registers guests |
| Guest-night cap not mentioned | Some regulations cap owner letting per year | The regulations, and model the cap |
| Operator drafts its own house rules | May conflict with approved building rules | Templates the juristic office already approved |
Insider tip: ask the operator for the trailing 12 months of performance on a comparable unit in the same building, and ask the juristic person separately how many units are being let short-stay. Where those two answers do not fit together, the gap is usually the part of the model you were not shown.
Getting it right: the short version
Establish licence status and read the regulations before you buy, because neither can be changed afterwards. Treat the statutory rule and the building’s private rules as two separate approvals you need. Where you have both, use a licensed operator and keep the paperwork filed. Where you do not, let on 30 days or more and build the numbers around that, rather than running a nightly model and hoping the complaint does not come. And whichever model you choose, get the operator’s net figures on trailing data from the same building rather than a projection.
Then run the due diligence sequence before any deposit, with licence status on the checklist alongside the quota.

Frequently Asked Questions
Only in a hotel-licensed building whose regulations permit it. Stays under 30 days are hotel business under Thai law, and the licence sits with the building rather than the owner.
It takes you outside the hotel licensing rule, which is the statutory question. The building's own registered regulations still apply and may impose a longer minimum or a registration requirement.
In practice a fine under the building's schedule, an instruction to remove guests, and platform delisting after a complaint. Enforcement is uneven across the island, which is not the same as absent.
No, and you generally cannot obtain one for a single unit in a residential tower. The licence attaches to the premises and is held at building or operator level.
Lower gross, but management runs around 8 to 15% of rent rather than 18 to 25% of revenue, with no cleaning cycle and far less vacancy. The net gap is smaller than the headline gap.
