Buying land to build a home: what to check

2026-10-24

Four checks before you pay a booking on an empty plot: title documents, land-use colour, road access, and electricity and water, then the steps to transfer day.

Before you pay a booking on an empty plot, you should know four things about it: which title document it has, what the land-use plan allows there, whether it reaches a public road, and whether electricity and water can connect. This guide explains each from government sources, then walks through the steps from agreeing to buy to transfer day. Happy Home helps check the documents and prepares each step with you, but we do not give legal advice; confirm every point with the responsible office before transfer.

The plot's title documents

A title document records who holds which rights in the land. The common ones are the title deed (โฉนดที่ดิน) and the น.ส.3 and น.ส.3 ก., according to the Land Department's encyclopedia. An ส.ค.1 is a notice of possession, not a title deed; land held only on an ส.ค.1 must be converted to a title deed or a certificate of utilisation before it can be transferred. Ask the seller for the documents, match the owner's name to their ID card, and confirm at the Land Office before you pay a booking.

The plot's colour on the land-use plan

The land-use plan divides land into colour zones by permitted use. The categories and colours for each province are set in the ministerial regulation enforcing that province's comprehensive plan, for example the Bangkok comprehensive plan. Look up a plot's colour in the Department of Public Works and Town & Country Planning's land-use plan search. If you plan to build a home, check that the colour's category allows housing, then confirm with the planning authority before transfer.

Access to a public road

A plot you can really build on needs a way in. An owner whose land is enclosed by other people's land, with no way out to a public way, often called landlocked land, may pass over the surrounding land to reach it, in exchange for compensation (Civil and Commercial Code, section 1349). If the plot does not touch a public road directly, walk the route yourself, ask about its width and condition, and have a lawyer review it before you book.

Electricity and water

Before you book, ask the local electricity and water providers whether the plot can connect, what extra work is needed, and what it would cost. For a new electricity connection, the Provincial Electricity Authority's application documents require proof of ownership or possession of the premises, so the plot's title documents should be clear before you apply.

From offer to transfer day

Once the four checks are done and the price is agreed, the next steps are the booking, the sale contract, and the transfer registration at the Land Office. The booking document for that plot sets the amount, the refund terms and the deadlines; read all of it before you pay. For the transfer fee and the taxes on transfer day, check who the contract makes responsible; if it is silent, agree it in writing before transfer day. If you take a loan, Happy Home prepares the documents against the list your bank confirms; the approval, the amount and whether the bank accepts that plot as security are the bank's decision.
