How Long Does a BIC Remain Valid for Commercial Properties in NSW?

If you're buying, leasing or fitting out a commercial property in NSW, you may have heard about a Building Information Certificate (BIC).

But what does it actually mean for your project, and how long does it last?Let’s break it down.

1. What is a BIC, and Why Might You Need One?

A Building Information Certificate is issued by your local council.

It confirms that an existing building or structure can remain as it is, without council requiring further works or demolition.

This certificate is often required when buying or leasing a commercial property that has undergone unauthorised work, or when you're lodging a development application (DA).

If you're a developer, cafe owner or commercial landlord, a BIC can be a vital piece of the puzzle to get council approval.

At Town Planning Sydney, we often see commercial clients needing a BIC during lease negotiations or when preparing for a shop or office fit-out.

It can help avoid compliance issues down the track and smooth the path to DA approval or a Complying Development Certificate (CDC).

2. So, How Long Is a BIC Valid?

A Building Information Certificate remains valid for seven years from the date of issue.

During that time, the council cannot take enforcement action on the works covered by the certificate.

This means that, as long as the structure remains unchanged, you’re protected from fines, notices or orders related to unauthorised works covered in the BIC.

That’s why many experienced planning consultants recommend getting a BIC when buying or leasing older commercial properties in NSW.

It’s a smart form of risk management and offers peace of mind to investors, landlords and tenants alike.

3. What Happens If You Make Changes During That Period?

If you lodge a new development application or make modifications to the structure after the BIC is issued, the original certificate may no longer apply to those changes.

In those cases, you’ll likely need a new BIC or updated council approval.

For example, one of our clients recently took over a hair salon that had unauthorised plumbing work.

The previous owner had secured a BIC.

However, when the new owner wanted to expand the layout, a fresh DA approval was needed, and the BIC didn’t cover the new scope.

This is where proper NSW planning advice makes all the difference.

Getting clear guidance from a planning consultant early in the process can save you thousands later.

4. When Should You Apply for a BIC?

We advise applying for a BIC before lodging a DA, especially if there’s any doubt about previous building work.

This is common in older commercial strips, food premises or retail spaces that have been modified over the years without proper records.

Town Planning Sydney regularly assists business owners with planning advice when councils request a BIC as part of the DA approval process.Having in-house drafting services also means we can prepare any supporting architectural drawings required for your application.

5. Does a BIC Guarantee DA Approval?

Not exactly.

A BIC only confirms the building, as it stands, is acceptable to council.

It does not replace the need for a DA or CDC if you plan to change the use, layout or structure of the premises.

However, it often supports your development application by resolving questions about existing compliance.

It also reduces the risk of delays due to prior unauthorised work.

As planning consultants working across NSW, we often integrate BIC applications into a broader strategy that includes DA support, architectural drafting and council negotiations.

Knowing when and why to use a BIC is just one part of smart town planning.

For commercial property owners and tenants, it can be the difference between a smooth project and a drawn-out compliance issue.
