Planning a commercial or retail fit-out in NSW: exempt, complying development or DA, and what to check before you sign

A new lease, a refreshed shopfront or a reconfigured office floor usually comes with a deadline. What can quietly push that deadline out is the approval pathway. In NSW, a commercial or retail fit-out may be exempt development, complying development, or work that needs a development application (DA), and the answer often depends on details that are easy to miss when signing a lease or accepting a quote.

This article explains the three pathways in plain English, the common triggers that move a fit-out from one pathway to another, and the certification steps that sit at the end of the job.

What the rules say

Exempt development. The NSW Government describes exempt development as very low impact work that may not need planning approval, but only if the proposed works meet the exempt development standards in the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 (the Codes SEPP). A 2024 Department fact sheet on Codes SEPP updates notes that minor internal and external building alterations are specified as exempt development, and that mechanical air handling systems were clarified as not exempt. The Codes SEPP also allows some changes of use to be exempt, subject to conditions, including that the new use must not breach any existing condition of the most recent development consent for the premises.

Complying development. The Department describes complying development as a combined planning and construction approval for straightforward development, determined by a council or an accredited certifier. The Department’s pocket guide to complying development for business and industry lists internal alterations such as fit-outs as a type of complying development, and says a change of use can be combined with alterations or a fit-out in one application. The relevant code in the current Codes SEPP is the Industrial and Business Alterations Code (Part 5). The pocket guide notes approval can take as little as 10 to 20 days, and that the work must comply with the relevant requirements of the Building Code of Australia. The NSW Government exhibited proposed changes to the Codes SEPP between May and June 2026; these are proposed, not in force, and this article describes the current rules.

Development application. Where a fit-out cannot meet the exempt or complying standards, it generally needs development consent through a DA. The Department describes local development as the most common type of development in NSW, with consent usually issued by the local council. After consent, a construction certificate is required before building work starts.

What it means in practice

The same fit-out can land on a different pathway depending on the site and the scope. Common triggers worth checking early:

• Change of use. Moving from, for example, an office use to a food or health use is a different question from refreshing an existing shop. A change of use may be exempt, complying or a DA depending on the categories involved and the existing consent.
• Heritage. The pocket guide states that complying development alterations are excluded on heritage items, and that some works, such as shop front upgrades and mechanical ventilation, are not permitted as complying development in heritage conservation areas.
• Land exclusions. The guide lists land-based exclusions, such as certain acid sulfate soil classes, high bushfire risk land and significant contamination.
• Services and structure. Mechanical ventilation, new structural openings or changes affecting fire separation or exits can take work outside the simple pathways.
• Fire safety and access. Ask your certifier early whether the proposed work triggers any fire safety or accessibility upgrades to the existing building.

Certification at the end of the job. Service NSW states that you must get an occupation certificate to use a new building or change the use of an existing building, issued by your local council or a private certifier once the building is suitable for occupation under its building classification. Where a building has essential fire safety measures, the Department’s fire safety certification page explains that a fire safety certificate is issued by or on behalf of the owner when new building work is complete, and that an annual fire safety statement is issued each year for an existing building, under the Environmental Planning and Assessment (Development Certification and Fire Safety) Regulation 2021. For a tenant, that means fit-out work touching sprinklers, detectors, exit signs or egress paths needs to be coordinated with the landlord’s fire safety obligations.

What owners and clients may want to consider

General points only, not advice on any particular project:

• Confirm the pathway before you sign. Where possible, get the approval pathway confirmed by a registered certifier or council before committing to a lease start date or fit-out programme.
• Check the existing consent. The approved use and conditions for the premises affect whether a change of use is straightforward.
• Read the lease fit-out clauses. Landlord approval, building rules, base build services and make-good obligations often shape the scope as much as planning rules do.
• Allow for certification time. Inspections, fire safety certification and the occupation certificate sit at the end of the job, when trading dates are closest.
• Brief the builder on the whole pathway. A quote that assumes exempt development may change if the work turns out to need a complying development certificate or DA.
