Commercial Change of Use in NSW: Do You Need Council Approval?

You’ve found the right premises, signed the lease, and you’re ready to fit it out. Then someone mentions you might need approval to use the space for your business — even though you’re not knocking down a single wall. It catches a lot of business owners and investors off guard, and getting it wrong can mean operating unlawfully.

Here’s how change of use works in NSW, when you need approval, and the fast-track that can save you weeks.

What “change of use” actually means

In planning terms, the use of a premises is a regulated thing in its own right — separate from the building. Turning a retail shop into a café, a warehouse into a gym, or an office into a medical practice is a change of use, and it can require approval even when no building work is involved.

Why? Because a different use can change the demands a site places on its surroundings — parking, traffic, noise, waste, operating hours, and public amenity. Councils need to be satisfied the new use suits the zone and complies with the relevant controls before it starts.

The three questions that decide it

Before you commit to a lease or a fit-out, work through three questions:

• Is the new use permissible in the zone? Every use is either permitted (with or without consent) or prohibited under the land’s zoning. Start by confirming your zone using the NSW Planning Portal’s Spatial Viewer.
• Does the new use change the building’s classification? Building uses are classified under the National Construction Code (NCC). A change that shifts the building’s classification almost always triggers approval, because it changes the building standards that apply.
• Does it involve building work? Fit-outs, new walls, mechanical exhaust, accessibility upgrades — building work can pull a simple use change into a more involved approval. Your answers determine which of the three pathways below you’re on.

Pathway 1 — Exempt development (no approval needed)

Some changes of use can be carried out without any approval at all. To be exempt under the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 — the “Codes SEPP” — the change generally has to satisfy conditions including:

• the current use is an approved, lawful use;
• the new use does not change the building’s classification under the NCC;
• the change does not involve building work, other than work that is itself exempt; and
• the premises and land aren’t of an excluded type (for example, heritage-listed land or critical habitat are carved out). Minor internal work during the change can still be exempt — think installing workstations, re-carpeting, repainting, swapping light fittings, or upgrading existing sanitary fittings. The practical rule councils themselves suggest: assume you need some form of approval until you can prove you don’t.

Pathway 2 — Complying development (the fast track)

If your change doesn’t qualify as exempt but meets a defined set of standards, it may be complying development — approved via a Complying Development Certificate (CDC) issued by council or a private certifier, without a full DA. For commercial premises, the relevant standards sit in the Codes SEPP’s commercial and industrial provisions (including the Commercial and Industrial Alterations Code).

The attraction is speed: a CDC can often be issued in around two weeks, against the much longer timeframe of a council DA. Complying development can’t be done on all land, though — a Section 10.7 planning certificate is the way to confirm your site meets the land-based requirements before you rely on this path.

Pathway 3 — Development application (the full route)

If the change is neither exempt nor complying — which is common for uses that materially affect parking, traffic, noise or amenity — you’ll need a development application to council. The DA is assessed against the zoning, the Development Control Plan, and the building regulations, and depending on the use may need to address parking, waste, hours of operation, acoustic impacts, and (for food or health uses) other regulatory requirements.

It’s slower and more involved than a CDC, but for many genuine commercial changes it’s the only valid pathway — and lodging a well-prepared DA the first time is far cheaper than fixing a rushed one.

A note on existing use rights

If a premises has a use that was lawfully established but later became prohibited under a new LEP, it may carry existing use rights under section 106 of the EP&A Act. That can allow the use to continue — and in some circumstances expand — even though the zoning no longer permits it. Existing use rights are valuable but technical, and they hinge on the use being lawfully commenced and not abandoned. If you’re buying or leasing a property whose use doesn’t match the current zoning, this is worth checking carefully.

The bottom line

A change of use is a planning decision, not just a lease and a fit-out. Before you sign anything, confirm the zone, check whether the new use changes the building’s NCC classification, and work out which pathway you’re on — exempt, complying, or DA. The earlier you do it, the more options you keep, and the lower the risk of finding out after you’ve committed.
