Building Permit for a Roi Et House: Where to Apply and What Documents Do You Need?

Where Do You Apply for a Building Permit for a Roi Et House?

A building permit for a Roi Et house must be filed with the local government office covering the land: the Subdistrict Administrative Organization (SAO, called Or Bor Tor in Thai) outside municipal areas, or the municipal office (thetsaban) inside municipal boundaries. The same office reviews the plans and issues either a permit or a construction notification receipt.

The main law covering this is the Building Control Act B.E. 2522 (1979), which allows an ordinary residential house to use the notification route under Section 39 bis instead of a full permit application, provided the paperwork and plans meet the required format. This generally shortens the process somewhat.

Whether filing for a permit or a notification, prepare every document completely the first time. Any missing paperwork or plan that does not match the requirements sends the whole filing back for correction, which takes longer than preparing everything properly from the start.

What Documents Does a Roi Et House Building Permit Require?

The core document is the construction permit application form (locally called Kor.1), along with a site plan, construction drawings, and specification sheets in roughly 5 sets (approximately, per Yotathai’s civil-engineering knowledge portal). If the house is large or structurally complex enough to exceed the threshold the law sets, a structural calculation sheet signed by a licensed engineer must also be attached.

Personal documents required include a copy of the landowner’s ID card and house registration, plus land title documents such as the chanote (full title deed, the strongest form of Thai land ownership) or Nor Sor 3 Gor. If the land is registered under someone else’s name, written consent to build on that land is also required. Foreign nationals generally cannot own land in Thailand outright, so a foreign buyer’s name usually cannot appear directly on the land title.

If the house falls under the category requiring a licensed designer and site supervisor, you will also need the designer’s certification letter (Nor.2) and the site supervisor’s letter (Nor.4), along with copies of their professional licenses from the Council of Engineers or the Architect Council.

How Long Does a Roi Et House Building Permit Take?

Under Section 39 bis of the Building Control Act, the notification process has a combined service time of roughly 45 working days (approximately), covering document completeness checks and the local officer’s review of the construction drawings (based on the government’s public service manual for Section 39 bis notifications).

If the local officer later finds the documents incomplete or incorrect, the owner gets an order to fix them within 7 days of being notified. Separately, the local officer has up to 120 days from issuing the notification receipt to review the drawings, which is a review window rather than an expiry date for the receipt (based on the Building Control Act B.E. 2522, Section 39 bis).

The actual time in Roi Et can run a little shorter or longer than this framework, depending on how complete the submitted paperwork is and how much workload the local office has at the time. Filing as soon as the house plans are finished helps avoid falling behind the planned construction schedule.

What Are the Risks of Building Without a Permit?

Construction without a permit or proper notification can be ordered stopped the moment a local officer discovers it, and in some cases parts already built may have to be demolished if the officer decides the issue cannot be corrected.

A house without a permit or notification receipt also runs into trouble later when applying for a house registration number, plus permanent electricity and water meters, since these offices typically ask to see the construction permit as supporting evidence.

If you need a construction loan from a bank, the permit documents are also standard paperwork banks ask to see. Skipping this step to save time usually comes back as a bigger problem at several later stages.

How Does Permit Timing Affect Your Construction Schedule?

Many homeowners start counting construction days from the day they sign the contractor’s contract, without budgeting time for the permit stage, which can take roughly one to two months (approximately). That pushes the entire schedule back from step one.

Having the house plans and documents ready before finalizing the contractor agreement lets you file for the permit the moment you are ready, and in some cases start site prep and foundation work in parallel while waiting for approval, if arranged with the local office in advance.

For people working in Bangkok or elsewhere who are building back home in Roi Et, planning the permit timeline ahead helps pin down the actual move-in date more accurately, instead of repeatedly pushing it back.

Let a Team Familiar With Local Procedures Handle Your Roi Et Building Permit

Each sub-district office and municipality in Roi Et can have slightly different review details. A team that has filed in that specific area before knows what extra documents officers tend to request and helps cut down on unnecessary revision rounds.

OBILIS handles the building permit process for homeowners as part of its service, from preparing plans that meet the requirements through to filing with the local authority across Roi Et and the wider Isan region.

To get a rough idea of your budget, try the house budget planner, or contact the team to discuss the details.

Before starting construction, ask your contractor or builder directly who files the permit and roughly how many days it takes, so you can plan payment milestones and move-in dates more accurately from the start.
