In the architecture course, there’s no way you would not have heard the word ‘setback’. Setback refers to the space left in between the built area and the boundaries of a site according to the local regulations.
These regulations are put in place to ensure that a building does not obstruct or encroach on nearby buildings and other structures.
Providing proper setbacks ensures proper and easy access into the plot.
One of the main reasons for providing setbacks for a building is to ensure safety to the users during an accident or a calamity.
Providing setbacks reduces obstructions caused to the nearby buildings.
Setbacks provide privacy not only from the nearby buildings but also from the roads.
The provision of proper setbacks also reduces the level of noise from the neighbouring buildings and traffic from the roads.
Setbacks allow space for designing structures which enhance the beauty of the site.
Setback values depend on the type of building that will be constructed on the site.
Most of the time, the area of setback is proportional to the size of the site.
The site which opens on two sides has different amounts of natural light and ventilation available compared to the ones with only one. Naturally, setback rules also vary depending on this.
Height of the building refers to the number of floors or more accurately, the FAR of the building.
The size of the access road also plays a part in deciding the length of the setback.
Presence of a protected area or a water body near the site anlo affects setback specifications.
It is extremely important to know the setback length before buying a house or a plot. If the rules are not followed, the owner shall be penalised and forced to reconstruct according to the regulations.
Each state and locality has its own regulations based on its resources, roads and geography. Refer to the official documents to get the correct values.
Not following proper setback rules is a punishable offence in India. Likewise, if your neighbours don’t follow these regulations and encroach into your area, you can take them to court.
