Heritage overlays are one of the most consequential planning controls on a property. They affect what you can build, how you can renovate, and — critically — what a site is worth. Yet sourcing reliable, up-to-date heritage data across Victoria has historically meant trawling through 79 separate council planning portals.
That changes today. Mapview now provides complete heritage overlay coverage across all 79 Victorian local government areas, normalised into a single, consistent dataset.
What’s in the Dataset
For every heritage-affected property in Victoria, Mapview now displays:
- Heritage overlay identifier — the HO number from the relevant local planning scheme
- Significance level — local, state, or national significance where classified
- Statement of significance — the council’s written description of what makes the property significant
- Conservation objectives — what the overlay is trying to protect
- Permit triggers — exactly what works require a planning permit under the overlay
- Victorian Heritage Register cross-reference — linked to the VHR entry where applicable
Why Full Coverage Matters
Before this update, Mapview had heritage data for metropolitan Melbourne and the major regional cities. Rural and peri-urban councils — places like Surf Coast, Indigo, Macedon Ranges — had gaps.
Those gaps created real risk for professionals. A property developer acquiring a site in a regional area could miss an HO entirely if they relied only on Mapview. Now that risk is eliminated.
How to Access Heritage Data
Heritage overlay information is visible on any Victorian property in Mapview:
- Search for an address or click a property on the map
- Open the Planning tab in the property panel
- Heritage overlays are listed under Overlays, with the full detail panel available on click
Heritage data is available on all plans, including Free. The statement of significance and detailed conservation objectives are available on Professional and Business plans.
Working With Heritage Properties
If you’re regularly working with heritage-affected properties, a few tips for getting the most from this data:
- Use the overlay boundary layer — toggle Heritage Overlays in the map layer panel to see which properties in an area are affected before drilling into individual sites
- Check permit triggers before advising clients — the triggers vary significantly between overlays; some require permits for all external works, others only for demolition
- Cross-reference with the VHR — state-significant properties listed on the Victorian Heritage Register have additional restrictions; the Mapview panel links directly to the VHR entry
What’s Next for Heritage Data
We’re currently working on extending our heritage overlay coverage to New South Wales and Queensland, where similar fragmentation across local councils creates the same discovery problem. We expect to announce NSW coverage later this year.
