Membership of the Building Designers Association of Queensland (BDAQ) is open to building designers who are licensed by the Queensland Building Services Authority (BSA) in any of the Building Design or Builders Licence classes.

There are also membership categories for anyone who has an interest in building design. A growing group of design students are joining BDAQ to make sure they are up to date with the latest information and are gaining great value from just mixing with experienced members. Employees of building designers, architects and others are also finding value from their associate membership. Corporate members are generally manufacturers or suppliers of products or services to the building industry.

Only those licenced by the BSA, registered architects or registered engineers are permitted to design buildings and prepare plans for builders or consumers in Queensland.

BDAQ was formed in 1990 to give recognition to a profession of critical importance to the building industry. It is estimated that between 75 and 80% of dwellings and around 45% of commercial buildings are designed by Building Designers.

BDAQ operates with a branch structure comprising 11 branches covering all areas from Far North Queensland to the Gold Coast and has a close association with the Building Designers Association of the Northern Territory (BDANT).
