What Happens if I Build Something Without Approval?

In NSW, building without DA approval or the correct planning permit can lead to serious consequences.

Many homeowners assume small structures or renovations don’t require consent. As a town planner in NSW, I regularly assist clients who discover after the fact that they’ve breached building regulations NSW.

You May Receive a Council Order or Demolition Notice

The most common outcome of unauthorised works is a council order. This could be a stop-work notice, a direction to lodge a development application, or, in serious cases, an order to demolish the structure.

We once assisted a client in Ryde who added a carport in a flood-prone zone. They had no idea it required DA approval. Council issued a demolition order.

We were brought in to prepare a statement of environmental effects for NSW DA, respond to compliance issues and negotiate a formal Clause 4.6 variation request NSW. Without expert guidance, the structure would have been removed.

You May Struggle to Sell or Insure the Property

Unapproved structures can cause major delays when selling a property. Buyers and solicitors will flag anything that lacks proper council approval.

You might also find your home insurance is voided if a claim arises involving unapproved works.

This is especially important for those adding studios, decks, or secondary dwellings. A proper council submission for secondary dwelling NSW ensures your development is recognised and compliant under NSW planning controls.

Some Minor Works May Qualify as Exempt Development

Not all works require formal approval. Certain minor changes may be classified as exempt development under NSW planning legislation.

However, many people misunderstand the rules. A raised deck over 1 metre or a front fence on a corner lot can still trigger compliance issues.

That’s why early planning advice is crucial. A planning consultant can confirm whether your proposal qualifies or whether you need a planning permit NSW.

Can You Get Approval After the Fact?

In many cases, yes. Retrospective approval is possible, but it’s not guaranteed. It usually involves lodging a full development application, justifying non-compliance, and often addressing complex planning concerns.

We recently worked with a client in Penrith who enclosed a veranda without approval. We helped prepare a complete town planning submission, including a heritage impact statement NSW town planning and a supporting statement of environmental effects.

The application was approved with minor conditions. But the process took months and cost far more than if approval had been obtained first.

The Role of a Town Planner in Managing the Risk

A town planner near me specialising in NSW DCP can assess your existing works, advise on next steps and lodge the necessary documentation.

Whether you need help with dual occupancy, subdivision, or a commercial change of use, a qualified NSW town planning consultant for subdivision approval can reduce delays and protect your investment.

Ignoring approval doesn’t just risk fines. It can derail future projects and limit what you can do with your property.

Town planning services for residential development NSW exist to prevent these issues and secure compliant outcomes.
