A Heritage Overlay is a council planning control that protects historically or architecturally significant properties in Melbourne. It may require a planning permit for demolition, extensions, or façade changes. While renovations are still possible, owners must comply with heritage rules before altering or developing the property.

If you own, or are thinking of buying a property in Victoria, you may discover it is affected by a Heritage Overlay.

For some owners, that raises immediate concerns:

Can I renovate?

Can I extend?

Will this affect the value of my property?

At Red Door Conveyancing, we often review contracts where a Heritage Overlay applies. Here’s what it means and how it may impact you as a property owner in Victoria.

Where Does the Heritage Overlay Information Appear?

If you are buying property, the Heritage Overlay will typically be disclosed in:

  • The Vendor Statement (Section 32)
  • A planning certificate
  • The planning property report

As conveyancers, we carefully review this information and explain what it means in practical terms for our clients.

What Does a Heritage Overlay Restrict?

Restrictions vary depending on the specific overlay and council, but commonly include:

External Alterations

You may need a planning permit to:

  • Demolish part or all of the building
  • Alter the façade
  • Add extensions visible from the street
  • Remove or alter heritage features

Trees and Landscaping

Some overlays protect significant trees or garden elements.

Subdivision

Subdivision may require additional assessment and approval.

Does It Mean You Cannot Renovate?

No, but you must obtain the correct approvals.

Many Victorian homeowners successfully renovate heritage properties. However, councils generally aim to:

  • Preserve original architectural features
  • Maintain the character of heritage streetscapes
  • Prevent inappropriate modern alterations

Each local council applies its Heritage Overlay controls slightly differently. For example, properties in inner-city areas such as Melbourne, Yarra, or Stonnington often have stricter heritage considerations due to the age and character of those suburbs.

Will a Heritage Overlay Affect Property Value?

It depends.

For some buyers, heritage status is highly desirable because it:

  • Protects neighbourhood character
  • Prevents overdevelopment nearby
  • Maintains aesthetic appeal

For others, renovation limitations may reduce flexibility.

From a legal perspective, the key issue is not whether it affects value — but whether buyers fully understand the restrictions before signing a contract.

What Should Buyers Do Before Signing?

If a Heritage Overlay applies, buyers should:

  1. Review the Section 32 carefully
  2. Obtain planning advice if major renovations are planned
  3. Check whether internal alterations are also affected
  4. Confirm whether trees or outbuildings are protected

As conveyancers, we explain what is disclosed in the contract and flag when further planning enquiries are advisable.

What About Demolition?

In many cases, demolition of a heritage property requires a planning permit — and approval is not guaranteed.

If you are purchasing with the intention of knocking down and rebuilding, it is critical to investigate this before signing an unconditional contract.

How Red Door Conveyancing Assists

At Red Door Conveyancing, we:

  • Review and explain Heritage Overlay disclosures
  • Identify whether the overlay appears standard or more restrictive
  • Flag potential risks for redevelopment plans
  • Work alongside your planning consultant if needed

Understanding planning controls before committing to a purchase can prevent costly surprises later.

A Heritage Overlay does not mean you cannot improve your property but it does mean additional planning controls apply.

For Victorian property owners, heritage protection is part of what gives many suburbs their charm and long-term appeal. The key is knowing your obligations before you renovate, extend or demolish.
