ACT – HENDRY building surveyors advise that since the Building Code of Australia does not apply to buildings retrospectively and is being continually revised and improved, building surveyors will advise most buildings in ACT do not comply with the current Building Code of Australia (BCA). A building surveyor’s BCA Audit performed by building surveyors will alert clients to deficiencies in the building. Any expansion, upgrade or change of use of the building however, can trigger the need for a BCA upgrade by the authorities designed to bring the building into compliance with current requirements. A BCA audit would pre-empt these conditions, especially prior to applying for a building approval certificate.
