Completing Your Construction Project in Thailand

Bangkok Post, Corporate Counsellor Column

Before you embark on designing and building your dream home—or business—in Thailand, pause for a moment.  As exciting and full of potential as your project may be, the process of completing a construction project involves many rules and regulations, as well as reliance on contractors. Therefore, before committing yourself, you should know what you are getting yourself into and plan accordingly.

First, consider the nature of your construction project. Thailand has environmental and land-use restrictions that may impact possible locations for your project. Land-use and environmental restrictions are governed by the Town and City Planning Act B.E. 2518 (1975), by amendments to this act, and by ministerial regulations arising out of it.

The restrictions under the Town and City Planning Act differ from town to town and city to city. Their purpose is to formulate, execute, and enforce comprehensive city plans that promote sanitation, convenience, orderliness, attractiveness, utilization of property, public safety, economic development, social and cultural development and preservation, and so on. Land-use regulations in Thailand usually come in the form of Euclidean zoning plans that limit the uses of land in particular zones. The possible zones in Thailand include:

  • low-population residential zones;
  • medium-population residential zones;
  • commercial and high-population residential zones;
  • industrial and warehouse zones;
  • special industrial zones;
  • rural and agricultural areas;
  • recreational and environmental preservation areas;
  • national park areas;
  • educational institution areas;
  • Thai culture promotion areas;
  • religious institution areas;
  • government office and public utilities areas; and
  • communication and transportation areas.

On top of land-use regulations, there are often overlapping, location-specific environmental regulations. These regulations usually include height restrictions for buildings and restrictions on the percentage of land that can be developed.

Second, consider the design of your project. Thailand has standards for the design of building projects. These standards are outlined in the Building Control Act B.E. 2522 (1979), in amendments to this act, and in ministerial regulations issued under it. They can include standards relating to restrictions on the size, shape, and height of buildings; regulations regarding the number and design of bathrooms and toilets; and regulations prescribing the aesthetic features of buildings. Restrictions can vary based on Province, so it is important to contact the Land Department Office local to where you want to build to obtain detailed information on the restrictions.

Third, consider the construction of your project. Thailand’s construction, renovation, and alteration standards can be found in the Building Control Act B.E. 2522 (1979), in amendments to this act, and in ministerial regulations issued under it. Construction standards include quality and durability regulations regarding construction materials; regulations governing electrical, water, and gas systems; fire safety standards; requirements regarding the distance between buildings and the road or public land; safety standards in regard to construction; and so on.

Fourth, compile a reference list of permits, reports, and inspections that will be necessary for the completion of your project. A permit is required for most construction projects in Thailand. There are different types of permits, reporting requirements, and inspection requirements for construction projects, depending on their location and scope. For example, different permits and procedures are required for construction, alteration, demolition, removal, and change-of-use. Permits for construction projects can be obtained at the Land Department Office.

In order to be issued a building permit, you must already have—among other things—relevant infrastructure permits (such as water and electricity permits), relevant land development permits, and completed architectural plans. The exact list of permits, reporting requirements, and inspection requirements that will be relevant to the completion of your project will depend on the specifics of your project.

Fifth, remember that trust is good but control is better. Consider carefully who to engage in the design and construction of your project, and under which terms. Contract work is governed in Thailand by the Title pertaining to Hire of Work in the Civil and Commercial Code (Sections 587 to 607), but you will want to create a written contract between you and your contractors to ensure that expectations are clear. This will help you avoid problems down the road. A good contract should include, for example:

  • the goals and parameters of the contracted-for job, including a copy of the construction plans;
  • the price mechanism for determining the cost of the job;
  • the terms and method of payments;
  • the completion date;
  • liquidated damages for delays or breach;
  • who will provide materials and equipment;
  • quality specifications;
  • at what time the title to materials and equipment provided by the contractor passes to you;
  • insurance requirements for the project;
  • post-construction liability; and
  • mechanisms for dispute resolution.

These considerations should not stop you from pursuing your construction project in Thailand, but they should be born in mind. Otherwise, you may be opening yourself up to heavy fines, a prison sentence, the demolition of your construction project, and lawsuits.

The Land Department in Thailand’s Ministry of the Interior (MOI) plays a central role in ensuring the stability and legality of real estate transactions in the country. Its core responsibilities include issuing land title deeds, registering transactions (e.g., sales, mortgages, leases), conducting surveys for subdivision or consolidation of land, and providing information and guidance on land and property development laws. These administrative functions secure investor confidence and support transparency in the Thai property market, so any delay can have a significant impact. This is especially true for investors who depend on timely registration to secure or transfer property rights. Delays can create liquidity risks, postpone project timelines, and even reduce Thailand’s attractiveness as a real estate investment destination. This article explores the nature of these challenges, the legal framework governing the timelines for administrative actions, and remedies available under Thai law. Sources of Delay Procedural delays at land offices can arise for a variety of structural and operational reasons. These include approval processes that require several levels of internal review, heavy staff workloads, and occasional communication gaps within the bureaucratic chain. Many processes still rely upon manual documentation, which can prolong administrative steps and increase the likelihood of bottlenecks. Some delays stem from ongoing investigations into the legality of land titles. For example, a land title deed may have an annotation indicating that the title deed is under investigation to verify its legality. Even though this annotation does not legally prohibit the sale or transfer of the land, in practice, most prospective purchasers are reluctant to proceed with a transaction until the annotation is removed. As a result, the land can become effectively illiquid during the investigation period, leading to significant investment delays. While such investigations are essential to maintaining the integrity of Thailand’s land registration system, prolonged inquiries

Over the past two years—particularly since Thailand announced incentives for EVs, including tax exemptions and reductions—there has been a clear trend of manufacturers relocating their facilities to Thailand. This shift is reshaping the country’s industrial landscape and creating significant opportunities in the real estate sector for companies looking to establish or expand EV manufacturing operations in Southeast Asia. Incentive-Driven Market Transformation The government’s tax exemptions and reductions have proven effective in attracting foreign investment, with Chinese manufacturers currently dominating the market. Most EV parts and car manufacturers operating in Thailand are from China, reflecting the prominence of Chinese EV brands that have already established a presence in the country. The sector encompasses manufacturers of electrical equipment as well as companies seeking to establish facilities for producing electric vehicle components, parts, and accessories. The surge in activity is evident across Thailand’s EV manufacturing sector, with legal practices handling these transactions experiencing unprecedented demand. Industrial Real Estate Framework and Market Dynamics Thailand’s industrial real estate framework provides compelling advantages for foreign manufacturers, who typically face restrictions on foreign land ownership under the Land Code. However, foreign investors can benefit from exemptions to these restrictions if the land is located within industrial real estate zones designated by the Industrial Estate Authority of Thailand (IEAT) or they obtain investment promotion from the Board of Investment (BOI) if the land is located outside an industrial estate area governed by the IEAT. Both the IEAT and BOI provide special tax and nontax incentives, including foreign land ownership, with even greater incentives available for land situated within the country’s Eastern Economic Corridor (EEC). This regulatory advantage has sparked a parallel trend in land development. Industrial real estate developers in the EEC are actively consolidating land into large plots to develop new industrial estate projects, recognizing that

Thailand’s consumer protection authorities have strengthened oversight of residential leasing businesses following numerous complaints about unfair lease terms, including unjustified deposit forfeitures and excessive utility charges. The Contract Committee of Thailand’s Office of the Consumer Protection Board issued the Notification of the Contract Committee Re: The Stipulation of Residential Property Leasing as a Contract-Controlled Business B.E. 2568 (2025), published in the Government Gazette on June 6, 2025. The notification becomes effective on September 4, 2025, and repeals the prior notification issued in 2019. The notification prescribes two types of standard residential lease contracts: short-term residential lease contracts (for leases of not more than three years) and long-term residential lease contracts (for leases of more than three years up to 30 years or for the lessee’s lifetime). However, use of these standard contract forms is not compulsory, and parties may use any form as long as the terms do not contradict the notification’s requirements. Expanded Scope The notification expands the scope of enforcement to include any lessor with at least three residential units, while the 2019 notification applies only to businesses leasing five or more residential units. Hotels and dormitory operators are excluded, as they are regulated under other specific laws. Residential lease contracts entered into under the 2019 notification will remain valid and enforceable until the expiration of the contract. Any residential lease contract executed from September 4, 2025, onward must comply with the new notification. The notification also expressly extends its applicability to lease contracts made through online platforms. Electronically executed lease contracts must comply with the required and prohibited terms specified in the notification as well as applicable laws governing electronic transactions in Thailand. Mandatory Terms and Conditions Residential lease contracts must contain clearly legible Thai text no smaller than two millimeters in size and no more

On August 12, 2025, Vietnam’s Ministry of Agriculture and Environment submitted a draft law amending several provisions of the Land Law 2024 (“Draft Amended Land Law” or “Draft”) for government consultation and public comment. The Draft primarily aims to address three controversial issues in Vietnam’s land regime concerning (i) land pricing, (ii) land clearance, and (iii) the allocation of land outside auctions, following policy set out by Resolution 18-NQ/TW and the newly adopted Resolution 69-NQ/TW on land governance modernization. Land pricing is potentially one of the most important areas among the proposed reforms. The Draft, however, has notably not addressed a major concern recently raised by the public: When a project has been allocated or leased land, but the relevant authority has not yet issued the land-price decision, a “supplemental charge” continues to accrue for the entire waiting period. Under current rules, this charge is calculated at 5.4% per year on the ultimately determined land-use fee or land rent, materially shifting project economics and pricing risks to developers or end-buyers. Core Reforms on Land Pricing The Draft Amended Land Law sets out a number of reforms on land pricing, including the following: Land price tables: The Draft maintains provincial land price tables but clarifies the scope of application: They are used to determine land-related financial obligations of land users and compensation when the state recovers land; the government will detail the adjustment coefficient regime, ratios for land-use fee calculation by land type/user/form, and deductible infrastructure costs. Provincial people’s committees will continue to issue land price tables every five years, effective from January 1 of the first year in the cycle, with authority to supplement within the cycle as necessary. In provinces with cadastral maps and digital land price databases, the tables may be established down to the land-parcel level,
