SETBACK SPACES

What are setback spaces?

Set Back Spaces for Building Plan Approval means the open space around the building. It’s the space across the front, sides, or rear of a plot between the building and the street alignment or boundary. The height of a proposed building, the width of the plot, and abutting road width govern the Set Back Spaces.

Why Setback Spaces?

Set Back Spaces are essential for Building Plan Approval for a healthy and organised community life. It will provide light, ventilation, and privacy to the proposed building under consideration. Neighbours will also continue to enjoy light, ventilation, and privacy. Set Back Spaces will provide space for parking vehicles. In times of emergency, the open space around the building will aid the movement of fire tenders. Also, Set Back Space may prevent a fire from spreading to neighbouring buildings.

Most importantly, Step Back Spaces have a bearing on the floor area that can be constructed.
Because, though a Floor Space Index (FSI) of 2 is allowed for Non Residential Buildings, it can be achieved only after providing for Set Back Spaces.

    Sir, I own a building in corner plot with 30 ft road on one side and 20 ft road on other side. Plot size is 2160 sq.ft. I intend to settle it to my children subdividing into two halves who desire to demolish the existing structure and build separate structures. Can the setback in between the two structures waived? The buildings will be facing the 30 ft road. Another building and 20 ft will be on the sides. Yet another building on the back Please clarify.

      Such buildings are very common in old areas. Such houses/buildings without setbacks shall follow the guidelines as described for ‘Continuous Building Areas’. Only by the local body can declare the area/plot as Continuous Building Areas, so please verify with the local body to confirm.
      For areas declared as Continuous Building Areas – there is no need for side setback or rear setback. However front setback will be required as per the road width & height of the building.

    Sir,
    For hospital building <18.3 M setback allaround setback mentioned as 6M.
    My property has a common road (government road) 32 feet on one side(not frontage). Previous regulation mentions if side road is more than 23 ft no setback is needed.
    Do clarify whether setback of 6M needed for my property on the side where 32 feet common road is available (not planning to construct compound wall)
    Thanks.

      *Side set back on either side – 1.5 m (r) 5 feet
      *Rear set back – 1.5 m
      *Front set back will depend on your road width . Thank you 😊
      *Fsi area for your plot = 1920 × 2 = 3840 sq.ft .
      *after deduction of set back remaining area for your plot is = 25 × 50 = 1250 sq.ft ×3= 3750 .
      So upto 3 floors you can build. And stilt floor is not included in the calculations.

    Hi, I have 40*60 plot on 60 ft road. As per the set back rules do i have to have 4.5 m front set back. Am I correct? 4.5 m is about 15 ft which is too high.

      Please check the road width sir , if your plot is connected with the main road then you will have to provide 4.5 m set back. Major roads in chennai are within 100ft .

    I’m building a house in Chennai. If I’m doing a setback violation, but Fsi achieved is within the permissible limit, will I be charged a fee

    1. ChennaiRealties avatar

      The Authorities do not have the powers to condone the Violations of Development Rules after collecting a fee. Such violations will have to be regularised by a Government Order only.For more clarifications we would request you to consult a professional in this regard.
