# Bangladesh National Building Code (BNBC) 2020

> Minimum standards for design, construction, use, occupancy, and maintenance of buildings in Bangladesh.

The Bangladesh National Building Code (BNBC) 2020 was made under section 18A of the Building Construction Act, 1952 (Act No. II of 1953), repealing the Bangladesh National Building Code, 2006. It was published by the Ministry of Housing and Public Works as S.R.O. No. 55-Law/2020, and gazetted on 11 February 2021.

Its purpose is to establish minimum standards for the design, construction, quality of materials, use and occupancy, location, and maintenance of all buildings in Bangladesh, in order to safeguard life, limb, health, property, and public welfare.
