Up to 50 m², a habitable room needs <strong>7.5 m²</strong> of floor and <strong>2.1 m</strong> of width. Above 50 m², it needs <strong>9.5 m²</strong> and <strong>2.4 m</strong>. Height is <strong>2.75 m</strong> either way (UBBL 2016, Table 7.1).</p> <p>Delhi does not just take the national numbers. It has its own rule book, the <strong>Unified Building Bye-Laws 2016</strong>. The DDA notified it on 22 March 2016. The central government approved it first. A habitable room is a room you live in, such as a bedroom or a sitting room.</p>
