We’ve got your Clause 137 (3A) Report sorted.
Planning building alterations (internal) works or a change of use under a Complying Development Certificate (CDC) in NSW? If the existing building contains a performance solution report, then you’ll need a Clause 137(3A) Report.
This independent report confirms that the building works and or change of use remains consistent with the performance solution report for the existing building. Without it, a certifier can’t sign off on your CDC.
At Buildcert, we help commercial builders, developers, building designers, residential builders and property owners get compliance sorted, so there are no surprises holding up approvals, deadlines, or handovers.
[ Our approach ]
How we get your compliance locked in.
01
Review Your Performance SolutionsWhat it is
A Clause 137(3A) Report confirms that the building works or change of use remains consistent with the performance solution report for the building.
The first step in the process is to send us your design plans, a copy of the current fire safety schedule, the existing performance solution report for the building, and any supporting documents for your CDC application. We’ll let you know if anything else is needed to complete the review.
Why it matters
Clause 137(3A) Reports are mandatory when your development involves building alterations (internal) or change-of-use projects where the existing building is subject to a performance solution report. Without it, your CDC can’t be approved. Getting it right at this stage means fewer delays later.
What you gain
Clarity and certainty. We’ll make sure you’ve got everything in place upfront, so there are no compliance issues or last-minute surprises holding up approvals.

What is a Clause 137 report, and when is it required?
Clause 137 of the Environmental Planning and Assessment Regulation sets rules around Complying Development Certificate (CDC) issuance. If the existing building is subject to a performance solution for a fire safety requirement under the Building Code of Australia (BCA) and your development comprises internal alterations or a change of use, you will need a compliance report to support your CDC application.
This confirms your design is consistent with the existing performance solution report.
