House Registration Number After Construction in Thailand: How Many Days Does It Take

What Is a House Registration Number, and Why File for It After Construction

Getting a house registration number means notifying the local registrar so they can issue an official house number and set up a house registration document (Thailand’s household registration book) for a newly completed structure. This is a step you take after the house is finished, not something bundled with the original building permit application.

Many homeowners focus entirely on getting the building permit and inspecting the contractor’s finished work, and forget that a completed house still has no official house number or registration document. That holds up several later tasks, such as transferring your civil registration to the new address or applying for a permanent electricity meter.

Filing for a house registration number should be part of your plan well before the house is finished, so the paperwork is ready and you can submit it the moment construction is actually complete.

How Many Days Do You Have to File for a House Registration Number

Under Thailand’s Civil Registration Act, a homeowner must notify the registrar to request a house number within 15 days of the date construction is completed (source: the Department of Provincial Administration, Bureau of Registration Administration).

In practice, “completed” generally means the point the house is actually ready to live in, not just the date you sign off on the contractor’s handover. Homeowners should start counting from that point and prepare to file as soon as the main construction work is genuinely finished, so the deadline isn’t missed unintentionally.

Central registration rules give the registrar a deadline for issuing the number: within 7 days of receiving your notification if the house sits inside that registration office’s area, and within 30 days if it sits outside that area. Homeowners should treat this as the benchmark when following up, and contact the local registration office right away if the deadline passes without a number being issued.

What Documents You Need Before Applying for a House Registration Number

The main documents usually required are proof of construction — such as the building permit or a certificate of construction from the local authority — a copy of the land title deed (chanote) or other land rights document for the land the house sits on, and the homeowner’s ID card.

In many areas you’ll also need a house notification form issued by the village headman or sub-district headman (known in Thai as “poo yai baan” and “kamnan”) confirming the house genuinely sits within that administrative area.

The exact document list can vary slightly between municipalities or SAOs (Subdistrict Administrative Organizations, known in Thai as “Or Bor Tor”). Call your local registration office ahead of time to confirm what’s needed, so you bring everything in one trip rather than having to travel back and forth.

How the Registration Office Processes a House Number Application

The homeowner submits all documents at the district registration office, municipality, or SAO covering the house’s location. Staff review the paperwork and may schedule a site visit to confirm the structure matches what was submitted before issuing a house number.

Once the documents check out and match the actual structure, the registrar issues the house number and prepares the household registration book for the homeowner, giving them an official document confirming their identity and address.

After getting the house number, homeowners typically follow up by transferring their civil registration to the new address and notifying utility providers like the electricity and water authorities so their accounts match the new house number — switching from a temporary meter to a permanent one with lower per-unit rates.

What Happens if You Don’t File for a House Number on Time

Thai civil registration law sets a fine for homeowners who fail to file for a house number within the deadline. Even though the fine amount itself is small relative to the cost of the house, the delays that follow are often more costly than the fine.

A house without a registered number generally can’t get a permanent electricity or water meter, meaning you’re stuck on temporary utility connections with higher per-unit rates, and it also holds up transferring your civil registration to your actual address. The longer this drags on, the more those extra utility costs add up.

Filing on time is worth it, especially for anyone planning to move in right after construction finishes, and for families with children who need the household registration to enrol them in a local school.

What to Prepare Before Moving Into a New House

Plan ahead as the handover date approaches: know where you’ll file for the house number, what documents you’ll need, and ask your builder or house-building company to prepare the certificate of construction as part of the final inspection, so you’re not chasing them down for paperwork after they’ve moved on to their next job.

If the land has multiple co-owners, decide in advance who will be listed as the registered house owner, to avoid confusion when you go to file — and make sure every co-owner has their supporting documents ready ahead of the appointment.

The OBILIS team advises homeowners in Korat and Roi Et to prepare their house registration paperwork alongside the final inspection step, so everything is ready the moment construction wraps up, with no need to chase documents down afterward.

Frequently Asked Questions

How much does it cost to get a house registration number?

This fee is generally low or negligible, but no single confirmed figure was found that applies across all areas in this round of research. Homeowners should confirm the exact fee with their local district office, municipality, or SAO before filing.

Can I apply for a house number without a building permit?

Generally, you should have proper legal proof of construction — such as a building permit or a certificate of construction — before applying for a house number. If you don’t have this document yet, sort out the permit situation first, so the house number process doesn’t get stuck later.

Can I get a house number and transfer my registration at the same time?

In practice these usually happen back to back: you get the house number and new registration book issued first, then transfer the homeowner’s or family members’ names into that household registration. Ask your local registration office whether both steps can be handled in a single visit.
