Exemptions for building works requiring approval

Property type

Landed

Learn about the exemptions for building works requiring approval which give landed house owners more design flexibility.

Homeowners who intend to build or renovate their landed property need not obtain approval from BCA if the proposed building works fall under the list specified on Building Works Not Requiring Approval.  For building works that do require approval, there are exemptions to the Building Control regulations for landed houses that are built for owner’s own use. These exemptions are meant to provide owners with more flexibility in the design of their own houses due to aesthetics or lifestyle preferences.

This page serves as an overview of the exemptions of the Building Control regulations.  Homeowners are advised to read this page together with their appointed Qualified Person (QP).
