What Does a Heritage Overlay Mean for Your Property in Victoria?

If you have just bought a property in a Heritage Overlay, or if your local Council has recently proposed one, you probably have a lot of questions.

The most common fear we hear is: “Does this mean I can’t touch anything?”

The short answer is no. A Heritage Overlay does not freeze a building in time. It is not a museum order. It is simply a planning control that manages how change happens, ensuring that new works respect the history of the area.

At Heritage Workshop, we help homeowners navigate these rules every year. Here is the practical reality of living and building within a Heritage Overlay in Victoria.

1. What is a Heritage Overlay?

In Victoria, a Heritage Overlay (HO) is a planning control applied to properties that have historical, aesthetic, or social significance.

It might apply to your specific house (Individual Significance) or, more commonly, to a group of houses and streets (Precinct Significance). Its goal is to protect the features that make the area special—usually the front facade, the roofline, and the streetscape character.

2. Can I Renovate or Extend?

Yes. In fact, most heritage homes need renovation to remain liveable for modern families.

The "Golden Rule" of heritage planning is usually: “Concealed from the street.”

• Rear Extensions: Single-storey rear extensions are almost always approved if they are not visible from the front street. Increasingly, you won't even need a planning permit.

• Second Storeys: Upper-level additions are possible, but they usually need to be set back so they don’t dominate the original heritage roofline.

• Interiors: Unless your property has specific "Internal Alteration Controls" (which is rare for residential homes), you can usually renovate kitchens, bathrooms, and floor plans without a planning permit.

3. Can I Demolish?

Demolition is the hardest part of heritage planning.

• Contributory Buildings: If your house is graded as "Contributory" (meaning it is part of the area's history), full demolition is rarely supported. However, you can often demolish some of the rear parts of the house to make way for a modern extension.

• Non-Contributory Buildings: If your house has no heritage value but sits inside an overlay, you can often demolish it, but the new build must still respect the neighbour's scale and character.

4. Do I Need a Permit?

If you are in a Heritage Overlay, you will almost certainly need a Planning Permit from your local Council for any new external works. This includes:

• Demolition or removal of any part of the building.

• Construction of an extension, carport, or garage.

• Constructing a front fence.

• External painting (only if "External Paint Controls" apply to your specific property).

To get this permit, Council will often ask for a Heritage Impact Statement (HIS). This is a technical report written by a specialist (like us) that explains why your design is appropriate and how it respects the history of the place.

Summary: Don't Panic, Plan Ahead.

Owning a heritage home is a privilege, but it adds a layer of complexity to any build. The secret is to get advice early.

On the plus side, you have certainty about how your street will look in the future, as well as the "bones" of your home to inspire you .

If you design a massive box on top of a Victorian terrace, Council will say no, and you will waste months on redesigns. If you engage a heritage consultant during the concept stage, we can guide your architect on exactly what heights, setbacks, and materials will get approved.
