According to data tracked by our analysts against Thai Ministry of Interior records, only 12-15% of condominiums on Phuket held an active hotel license under the Thai Hotel Act as of end-2025. On Koh Samui, our estimates put that share at approximately 8-10%. This legal constraint directly determines which rental business model is viable for any investor targeting short-stay income in Thailand.
Without a hotel license, a building cannot legally rotate guests on cycles shorter than 30 days. We monitor the license registry continuously, and enforcement has tightened: in 2025 alone, several dozen cease-and-desist orders were issued on Phuket against operators running nightly rentals from unlicensed buildings. The practical implication is clear - verifying a building's legal status comes before any other due-diligence step, well ahead of floor plan or sea view.
Quick answer
- A hotel license under Hotel Act B.E. 2547 is required for any rental shorter than 30 days, including condominium units
- The license is held by the building operator or management entity (developer, hotel operator), not by the individual unit owner
- Mandatory requirements include 24/7 front desk staffing, fire safety compliance, public liability insurance, and TM.30 guest registration with Immigration within 24 hours of check-in
- Based on our estimates, the licensing process costs a building 500,000 to 3,000,000 THB and takes 6 to 18 months
- Without a license, the only legal model is monthly rental (minimum 30 days) or annual lease
- On Phuket, the highest concentration of licensed projects is in Bang Tao, Layan, Kamala, and Surin; on Koh Samui, in Bophut (Fisherman's Village) and Chaweng
Options and scenarios
Scenario 1: Licensed building - nightly rental via operator pool
This is the model we track most frequently in Bang Tao and Kamala on Phuket. The owner purchases a unit in a project holding a valid hotel license and places it into a managed rental pool. The operator handles reservations, housekeeping, and guest check-in.
For a well-run 35 sq m studio in Bang Tao (Q4 2025 data), average daily rates run 3,200-4,500 THB in high season (November to March) and 1,800-2,800 THB in low season (May to October). We estimate average annual occupancy in this submarket at 65-75%.
Projected annual figures for a Bang Tao studio (based on our 2026 estimates):
- Gross revenue: 365 days x 70% occupancy x 3,200 THB average rate = 817,600 THB
- Operator commission (25-35% of gross, here at 30%): -245,280 THB
- OTA commissions (Booking.com, Airbnb, typically 3-15%): included in operator commission in this scenario
- Housekeeping, laundry, minor repairs: -65,000 THB
- Utilities (electricity, water, internet): -36,000 THB
- Common area maintenance (CAM) fee: -24,000 THB
- Unit insurance: -8,000 THB
- Net owner income: approximately 439,320 THB
At a purchase price of 4,500,000 THB, that implies a net yield of approximately 9.8% per year. We flag this as an optimistic scenario, contingent on strong occupancy and a capable operator.
Scenario 2: Unlicensed building - monthly rental
In areas such as Rawai and Nai Harn on Phuket, or Maenam and Lamai on Koh Samui, many projects carry no hotel license. The owner can legally let the unit only for periods of 30 days or longer.
Monthly rates for a 35 sq m studio in Rawai stood at 18,000-28,000 THB as of Q1 2026. Annual occupancy under a monthly model is meaningfully lower than in the nightly model - our estimate is 50-65%, as filling July-through-October inventory in Rawai is structurally difficult.
After deducting management fees, utilities, and CAM fees, net annual income in this scenario falls to approximately 120,000-170,000 THB, which translates to a net yield of 2.7-3.8% at the same purchase price.
Scenario 3: Guaranteed return schemes
Several developers on Phuket and Koh Samui market guaranteed return programs at 5-7% per year for periods of three to five years. Based on our review of these contracts, a recurring pattern emerges: the guarantee is built into the purchase price via a 10-20% markup above comparable market values, or it is funded from capital paid in by other buyers in the same project.
The hidden cost of the guarantee: if the purchase price carries a 15% premium and the guarantee runs at 6% for three years, the owner is effectively self-financing a significant portion of the 'guaranteed' income through the overpayment. Once the guarantee period expires, yields revert to market levels, which are typically lower than the headline figure suggested.

Occupancy seasonality by district
Our analysts track nightly rates and occupancy across key submarkets. The variation is material.
Phuket:
- Bang Tao and Surin - high-season occupancy (November to March) reaches 85-92%; low season (May to October) drops to 40-55%. Strong European and Middle Eastern demand base
- Kamala and Layan - high season 80-90%, low season 35-50%. Premium segment, higher rates, smaller total guest pool
- Rawai and Nai Harn - high season 70-80%, low season 30-45%. Less exposure to organised package tourism
- Karon - more even occupancy due to package-tour traffic: high season 80-88%, low season 45-55%
Koh Samui:
- Chaweng - highest occupancy on the island: high season 80-90%, low season 40-55%
- Bophut - high season 75-85%, low season 35-50%. Popular with longer-stay remote workers
- Maenam - high season 65-75%, low season 25-40%. Quieter area, lower rate potential, difficult to fill in the off-season
- Lamai - high season 70-80%, low season 30-45%
The key observation from our data sets: the occupancy gap between high and low season runs at 30-45 percentage points across most districts. Full-year net yield is therefore heavily dependent on the operator's ability to generate reservations from May through October.
Technical requirements for a hotel license
Hotel Act B.E. 2547 (2004), as amended in 2008, defines four categories of hotel-type premises. For condominium projects offering nightly rentals through a managed pool, the core requirements are:
- Registration with the Ministry of Interior - the property must appear in the official hotel register
- Fire safety compliance - extinguishers, smoke detectors, evacuation plans, and exit routes meeting Thai Fire Prevention and Suppression Act standards
- 24/7 front desk and on-site staff - continuous staffing is non-negotiable
- TM.30 guest registration - every foreign national must be registered with the Immigration Bureau within 24 hours of arrival, filed electronically
- Public liability insurance - a valid policy covering guest stays
- Permitted use certificate (Ror.Bor.) aligned with hotel or serviced-apartment use
- Juristic person resolution - in a condominium, a general meeting resolution by at least 50%+1 of eligible votes is required to authorise hotel operations
A point our analysts consistently raise with buyers: the individual unit owner does not apply for the license. The building management entity or hotel operator does. This means the license status must be confirmed at the building level, before purchase, through direct verification of ministry records.
Risks and mistakes
- Buying in an unlicensed building with a nightly-rental plan - the most common error we see in the market. Many operators on Phuket have historically run informal nightly lets, but enforcement through 2025 and into 2026 has become considerably stricter. Fines reach 20,000 THB per day of illegal operation
- Using high-season rates as the base for annual projections - doing so overstates projected income by 30-40% compared to what our full-year occupancy data supports
- Insufficient operator due diligence - in our data sets, the occupancy gap between a well-performing and a poorly performing operator in the same building can reach 15-20 percentage points annually
- Signing a guaranteed-return contract without reading the fine print - clauses allowing the developer to reduce or exit the guarantee under specified conditions appear regularly in the contracts we review
- Underestimating utilities and CAM fees - combined, these typically run 60,000-80,000 THB per year for a studio, which is a material drag on net yield
- Currency risk - rental income is denominated in THB while liabilities or wealth benchmarks may be in other currencies. The THB exchange rate moved within a roughly 6% band in 2025; this variance should be modelled into any yield projection
FAQ
Can I rent out a Phuket condo on a nightly basis without a hotel license?
No. The Thai Hotel Act requires a valid hotel license for any rental period shorter than 30 days, including individual condominium units within a building. The only legal alternatives without a license are monthly rentals (30 days minimum) or annual leases. Fines for unlicensed nightly operations can reach 20,000 THB per day.
Who applies for the hotel license - the unit owner or the building operator?
The license is obtained by the entity managing the building - typically the developer, a condominium juristic person, or a contracted hotel operator. An individual unit owner in a condominium does not apply independently. This is why verifying license status at the building level, before purchase, is essential.
What does it cost to obtain a hotel license in Thailand?
Based on our estimates, the cost to a building ranges from 500,000 to 3,000,000 THB, depending on the scale of the project and the scope of required upgrades (fire safety systems, front-desk infrastructure). The process typically takes 6 to 18 months from initial application to approval.
What is the yield difference between nightly and monthly rental on Phuket?
Based on data we monitor across Bang Tao and surrounding areas, nightly rental in a licensed building generates a net annual yield of approximately 7-10%. Monthly rental in the same area produces roughly 2.5-4%. The gap reflects higher effective daily rates and stronger occupancy in the licensed-nightly model, particularly during high season.
Are guaranteed-return schemes from developers worth considering?
Guaranteed returns of 5-7% per year are frequently embedded in purchase prices that carry a 10-20% premium over comparable units without the guarantee. Once that premium is accounted for, the effective yield typically falls to 3-5%. We recommend price-checking any guaranteed-return offer against current market listings for similar units in the same district before signing.
How does seasonality affect rental income on Koh Samui?
High season runs November through March. In Chaweng, occupancy reaches 80-90% at peak and drops to 40-55% in the low season (May to October). In quieter submarkets such as Maenam, the range is wider: 65-75% high season versus 25-40% low season. Annual yield projections must reflect the full-year average, not the high-season peak.
Which Phuket districts have the most licensed condominium projects?
The highest concentration of hotel-licensed condominium projects in our data sets is in Bang Tao, Layan, Kamala, and Surin - all on the western coast of the island. Licensed inventory in Rawai and Nai Harn is considerably thinner.
How does TM.30 guest registration work in a licensed property?
The hotel operator is legally required to register every foreign national with the Thai Immigration Bureau (TM.30 system) within 24 hours of check-in. Registration is filed electronically through the Immigration Bureau portal. Failure to comply carries a fine of up to 10,000 THB per unregistered guest. This obligation rests with the operator, not the individual unit owner.
What are the tax implications of rental income from a Thai property?
Rental income from property located in Thailand is subject to Thai income tax. Under the Thailand double-taxation agreement framework, income taxed in Thailand is typically exempt from being taxed again in the investor's home country under an exemption-with-progression method, though the precise treatment depends on the investor's country of tax residence. We recommend consulting a qualified tax adviser familiar with both Thai and home-country regulations before committing to a purchase.
