Lower North Shore planning changes are beginning to reshape what can be built across Mosman, Cremorne, Neutral Bay, Crows Nest and surrounding suburbs.
The changes are significant because some residential properties that previously had relatively modest development controls may now sit within areas where additional housing types, greater height and higher floor space ratios can be considered.
For homeowners, investors and anyone thinking about selling, the important question is no longer simply “What is my house worth?”
It may also be:
“What could this land potentially be worth under the new planning controls?”
Lower North Shore Planning Changes Are Already in Effect
The NSW Government’s Low and Mid-Rise Housing Policy applies to residential areas within an 800-metre walking distance of nominated centres and transport hubs.
On the Lower North Shore, nominated locations include Spit Junction, Cremorne, Neutral Bay, Crows Nest, Milsons Point and Victoria Cross.
The policy is designed to encourage more housing close to shops, services and public transport, including terraces, townhouses and apartment buildings.
What Can Be Built Within 400 Metres?
For residential flat buildings on qualifying R3 and R4 land within the inner 0–400 metre area, the State policy provides non-discretionary standards of up to:
- 6 storeys
- 22 metres building height
- 2.2:1 floor space ratio
For qualifying R3 and R4 sites in the 400–800 metre outer area, the standards are up to:
- 4 storeys
- 17.5 metres building height
- 1.5:1 floor space ratio
These are significant changes compared with the controls that historically applied to many Lower North Shore residential sites.
But they do not mean every property can automatically be developed to those limits. Zoning, heritage, site constraints, access, design requirements and other planning controls still need to be considered.
Mosman Is Already Seeing New Development Applications
This is not theoretical anymore.
Mosman Council is already assessing a number of development applications lodged under the Low and Mid-Rise Housing Policy.
Examples include 17 Moruben Road, where a six-storey residential flat building has been proposed, and larger applications at Cowles Road, Bond Street, Awaba Street and Rangers Avenue/Brierley Street. Several applications have also proceeded to Land and Environment Court appeals.
This shows how quickly the new planning environment is beginning to affect development activity across the area.
Heritage Still Matters
Heritage is particularly important in Mosman.
The Low and Mid-Rise Housing Policy does not apply to land containing a heritage item, although heritage conservation areas are treated differently and may still fall within the reforms.
That means two neighbouring properties can potentially have very different development outcomes depending on their zoning, heritage status and individual site characteristics.
Owners should therefore be careful about relying on a simple online map or a neighbour’s development approval.
Mosman’s Own Masterplan Is Also Moving Forward
At the same time as the State reforms, Mosman Council has been progressing its own planning work.
On 1 September 2026, Council formally lodged the draft Mosman Masterplan and draft Affordable Housing Contributions Scheme with the NSW Department of Planning, Housing and Infrastructure for Gateway Determination.
The State Government will determine whether those proposals can move forward to formal public exhibition.
That means Mosman property owners are dealing with both existing State planning reforms and further potential local planning changes.
Could Planning Changes Affect Property Values?
Potentially, yes — but not every property will benefit equally.
A site may attract greater interest if it has characteristics such as:
- favourable zoning
- proximity to a nominated centre
- sufficient frontage or site area
- the ability to amalgamate with neighbouring properties
- limited heritage or environmental constraints
- good access and development feasibility
On the other hand, a property may sit within a planning area but still face constraints that substantially reduce its development potential.
That is why owners should be cautious about accepting a simple price-per-square-metre comparison without understanding what a developer can actually build.
These Lower North Shore planning changes are already influencing how owners, buyers and developers assess property across the area.
Property Owners Should Understand the Site Before Selling
One of the biggest mistakes an owner can make is selling a property without first understanding whether the planning controls have changed its underlying development potential.
That does not mean every homeowner should become a developer.
It simply means that before selling, it can be worth understanding:
What is the zoning?
Does the Low and Mid-Rise Housing Policy apply?
Is the property within 400 metres or 800 metres of a nominated centre?
Are there heritage restrictions?
Could neighbouring sites be important to a future development?
Those questions can materially affect how a property should be marketed and who the likely buyers may be.
Thinking About Selling on the Lower North Shore?
At Axios Real Estate, we work throughout Mosman and the Lower North Shore and keep a close eye on the planning and development changes affecting local property owners.
If you are considering selling, or simply want to understand whether recent Lower North Shore planning changes may affect your property, speak with Mike or Kathy at Axios Real Estate on 0407 403 640 for a confidential discussion.
A property’s value is not always just about the house standing on it today. Sometimes the real question is what the site may be capable of tomorrow.
Lower North Shore planning changes are likely to remain an important issue for local property owners as new housing and development proposals continue to emerge.
