What are the regulations on setback of works in Vietnam?
The setback of works is the space between the red-line boundary and the construction boundary.
Based on the Vietnam National Technical Regulations on Construction Planning, the work (houses) may not be backward or be backward from the red-line boundary, depending on the width of the road and the height of the work, accordingly:
- The setback of works adjacent to traffic roads (for regional-level roads and above) is specified in the detailed planning and urban design project, but must satisfy the provisions in the Regulations table. The minimum setback distance is as follows:
Accordingly, for example, in case the road adjacent to the residential land lot is less than 19m wide and the house to be built is 24m high, the minimum setback is 04m.
At the same time, in the case of a building complex consisting of the base of the building and the upper tower, the regulations on the work setback are applied separately to the base of the work and to the upper tower in the direction of the corresponding height of each part.

- Drainage pipes of houses and do not exceed 0.2m from the boundary line and must be aesthetic, not losing the urban beauty.
- For houses with 2nd floor or more, when built with two overlapping border lines, the balcony or roof of construction umbrellas are allowed to exceed the red-line boundary by less than 0.2m. From a height of 3.5m or more, buildings with umbrellas, eaves, and balconies are allowed to cross the red-line boundary in compliance with some requirements.
- The overpass of the work must be smaller than the width of the sidewalk, to ensure the safety of the electrical network. Ensure the landscape architecture and aesthetics of the same house system in the area. The excess can only be a balcony, the roof is absolutely not built into a private room
- Especially ,the works where these two limit lines overlap need to be attended to avoid the unfortunate consequences that may occur when crossing the red-line boundary.
