Are there any restrictions on raising the height of a wall between 2.single houses in Pattaya ?

Thanks ,in advance for any response.

Why ask the experts here when the real experts on the building code is your local authority?

Derrrrr - Usual/obvious

barrier is language

Chonburi, I believe, is 3m. Ie. You can put a 600mm electric fence/spikes on a 2m wall and still be OK.

Amphur office will tell you.

Who owns the fence?

My understanding is that if the wall is on the property line it belongs equally to both properties regardless of who builds it. That way both property owners may affix things to their side of the wall.

My understanding also - EXCEPT where the wall is actually built on the land belonging to only one of the parties - in which case I understand the wall is owned by the person who owns the land on which the wall stands. And I understand this is very common

In which case it wouldn't be on the property line?

I resemble that remark.

Thai spouse has told me the legal max is 3 meters for Chonburi--we were discussing the height of the perimeter walls on a house we are building. 3 meters seemed a bit too much like a prison wall to me and we settled on 2.5 meters.

Thanks for that.. My neighbours are not polite people. I will build up to the 3 metres.

If you are in a housing project I would check first to see if there are any restrictions on wall height within the project.

You'd be amazed to learn that there's a thing called Google Translate, or you could use ChatGPT to translate.
Both can handle spoke English and Thai.

ChatGPT also answers your original question.

In Thailand there are some general legal rules about building or raising walls between neighbouring properties — but there isn’t a simple flat “Pattaya-only” rule. The main laws are national (Building Control Act and related Ministerial Regulations) and then local offices apply them through the local building authority.

Key points that typically apply to a boundary wall between two houses (not on a public road):

🔹 Height and building permit

• If the wall is below about 10 m high, it usually does not count as a building that needs a building permit.

• If a wall reaches about 10 m or more, the law treats it like a building and you must apply for a permit with local authorities.

🔹 Distance from the boundary

• For a wall without windows/openings, the national building rules allow it to be as close as up to the boundary line (0 m) without minimum distance if there’s no opening.

• If the wall has windows or openings facing the neighbour, then it’s typically required to be set back about 2 m from the boundary line.

(This is about general building block walls — these are from the Ministerial Regulation under the Building Control Act.)

🔹 Consent from the neighbour
Even if the law lets you build up to the boundary, it’s common practice to get written consent from the neighbour if it’s right on the boundary. That prevents disputes later, especially for drainage or structural issues.

🔹 Local Pattaya requirements
Chonburi Province / Pattaya may have its own enforcement practices, but typically they follow the national building control rules above. For anything unusual (higher than typical wall height, structural features), you would need to check with the Chonburi/Pattaya building or municipal office before construction.

If the plan that the neighbors will become more polite when you build the wall higher?

Are they very tall or peering over the fence on a step ladder? I would worry about the stability of a 3 metre tall wall.
