Do I Need Council Approval for My Project?

One of the most common questions we hear is, “Do I need council approval for this?” 

Whether you’re building a deck, adding a granny flat or changing the use of a shop, the answer depends on the type of development, your zoning, and the specific rules that apply under NSW planning laws.

As a town planner NSW based, I’ve seen simple projects delayed because the owner didn’t realise a development application was needed.

I’ve also helped clients fast-track work using the Complying Development pathway, which skips council assessment altogether.

When Is Council Approval Required?

If your project alters the land use, increases floor area or affects neighbours, you’ll likely need DA approval.

This includes things like new dwellings, secondary dwellings, dual occupancies, change of use or substantial alterations to existing buildings.

For example, we recently helped a client in a low-density residential zone who wanted to build a detached studio behind their house.

Although it looked like a basic addition, it triggered the need for a development application due to access and drainage constraints.

We prepared a detailed council submission for secondary dwelling NSW standards, and the DA was approved within normal timeframes.

On the other hand, some works fall under exempt or complying development.

These can be certified by a private certifier if they meet strict criteria, avoiding the full council process.

Planning Controls That Affect Your Project

Each council has different rules under their Local Environmental Plan (LEP) and Development Control Plan (DCP).

A planning consultant can interpret these documents and give you tailored planning advice.

We often assist clients with planning advice for dual occupancy NSW applications where the block size or frontage is borderline.

In many cases, we’ve lodged expert help with Clause 4.6 variation request NSW applications to support minor non-compliances, such as building height or lot width.

For properties in heritage areas, even minor changes may require a heritage impact statement NSW town planning compliant.

One client in Marrickville wanted to replace a fence, but it required council approval because the property was in a conservation area.

What About Commercial Projects or Subdivisions?

If you're converting a garage into a shop or using a warehouse for a new business, you'll need a town planner for commercial change of use NSW approval.

These often involve a development application with supporting documents, including a statement of environmental effects for NSW DA.

We recently assisted a developer with a subdivision proposal where multiple planning permits NSW wide were triggered.

Our team, acting as a NSW town planning consultant for subdivision approval, worked closely with council and engineers to address access, bushfire and drainage controls.

Start With the Right Planning Advice

Understanding whether you need council approval starts with zoning, overlays and site-specific issues.

A town planner near me specialising in NSW DCP requirements can provide advice before you spend money on plans or consultants.

From DA approval to town planning services for residential development NSW wide, getting early, accurate advice is the key to knowing how to get a DA approved in NSW and moving forward with confidence.
