Certificate of Design Compliance (WA)
What a Certificate of Design Compliance (BA3) is in WA: a registered building surveyor's sign-off that a design meets building standards before permit lodgement.
Ask Chalkline about this →A Certificate of Design Compliance (CDC) is a certificate issued by a registered private building surveyor in Western Australia confirming that a building design complies with the building standards under the Building Act 2011 (WA). It is prepared on form BA3 and lodged alongside a Certified building permit application (BA1). Obtaining a BA3 before lodgement is the key feature of the Certified Application pathway: the local government only checks procedural compliance, reducing the statutory assessment period from 25 business days (Uncertified) to 10 business days. All three registration levels of building surveyor (Level 1, Level 2, Technician) can sign a BA3 for a Class 1 residential building within their scope.
Also known as: CDC (WA context only), BA3, design compliance certificate.
