Building by-laws
Also called: Building regulations, Building codes · Topic: Human Settlements and Urbanisation in India · NCERT: Beyond NCERT
Meaning
Building by-laws are local rules that decide how a building may be built on a plot. They set the Floor Area Ratio (FAR), which is how much total floor space can be built on a plot. They also set the height limit and the setbacks, which are the open spaces a building must leave from the plot boundary. A fourth control is ground coverage, the share of the plot the building may cover. A city's urban local body or development authority usually frames these rules under state municipal or town planning laws. They matter because each extra floor adds people, cars and sewage to the same roads and drains. Loose by-laws can therefore overload a town beyond its carrying capacity, which is the most it can hold before its land, water and services break down.
Example
In Srinagar (Jammu and Kashmir), the building by-laws were amended in December 2025. In July 2026 they were extended to Housing Board colonies, which got extra FAR and smaller setbacks. Under FAR 200%, a 100 sq m plot can carry 200 sq m of floor space, for example two full floors.
Don't confuse with
- Master plan: a long-term land-use plan for the whole city that decides which zones are for housing, industry or green space. Building by-laws work at the level of a single plot or building, and they are meant to follow the master plan.
