# Bangladesh National Building Code (BNBC) 2006

> Predecessor to BNBC 2020; minimum standards for design, construction, use, occupancy, and maintenance of buildings in Bangladesh.

The Bangladesh National Building Code (BNBC) 2006 was prepared by a Steering Committee formed under the Planning Commission in 1991, with consulting services provided by Development Design Consultants Limited, and published by the Housing and Building Research Institute (HBRI) and the Bangladesh Standards and Testing Institution (BSTI). It was repealed and replaced by the [Bangladesh National Building Code (BNBC) 2020](/bnbc/index).

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