A Heritage Overlay (HO) is a planning control that applies to properties
of heritage significance — architectural, historical, social, or
scientific. In Melbourne, thousands of properties have Heritage
Overlays. The overlay can apply to individual properties (individual
heritage significance) or to an area (precinct heritage significance,
where your property contributes to the character of a significant
streetscape or precinct).
What Does a Heritage Overlay Restrict?
The Heritage Overlay affects different types of work differently.
Demolition of any part of a heritage-listed building or a building in a
heritage precinct requires a heritage permit. External alterations,
including new windows, changes to facade materials, new extensions
visible from the street, new fences, and changes to the roof, require a
heritage permit. Internal alterations are generally not regulated by the
Heritage Overlay, though there are exceptions for buildings of
exceptional significance.
What Can You Do Without a Heritage Permit?
Routine maintenance and repair of existing fabric in the same materials
generally does not require a permit. Interior alterations and
refurbishments (not affecting the external appearance of the building)
generally do not require a permit. Adding a new extension to the rear of
the property that is not visible from the street may be exempt from
heritage permit requirements — but this depends on the specific
overlay provisions and the individual property.
Designing a Heritage Renovation in Melbourne
Good heritage renovation practice involves what architects call
‘additions as new’ — designing modern additions that are clearly
distinguishable from the original fabric, but respectful of its scale,
form, and materials. The principle is that future generations should be
able to read the evolution of the building — old and new — clearly.
Heritage Permit Application Process
Heritage permit applications are assessed by the local council’s
heritage officer, who reviews the application against the heritage
overlay provisions and the applicable Heritage Design Guidelines. Most
councils also consult with Heritage Victoria for state-listed
properties. The assessment considers impact on heritage significance,
reversibility of changes, and compatibility of new fabric with existing
heritage fabric.

Frequently Asked Questions
Can I add a modern extension to my heritage home?
Yes. Modern extensions are generally supported by heritage guidelines
provided they are: set back from the street, secondary in scale to the
original building, and designed in materials and forms that are
complementary but distinguishable from the heritage fabric.
How do I find out if my property has a heritage overlay?
Check VicPlan (planning.vic.gov.au) — search your property address and
look for Heritage Overlay listings under ‘Planning Overlays’. You can
also contact your local council’s planning department.
How long does a heritage permit application take?
Heritage permit applications are assessed as planning permit
applications, with a statutory timeframe of 60 days. In practice,
straightforward applications may be decided in 6–10 weeks. Complex
applications may take 4–6 months.
