Town centres across the Northern Beaches, including Dee Why, are set for major residential changes under a state policy allowing medium-density housing near key transport and commercial hubs.
Housing Growth Across the Northern Beaches
The Low and Mid-Rise Housing Policy, introduced from July 2024, has reshaped residential zoning across Greater Sydney. It allows housing up to six storeys within 400 metres and up to four storeys within 800 metres of town centres and transport hubs.
Dee Why, Mona Vale, Forestville, and Frenchs Forest are among nine Northern Beaches centres affected. The changes apply to more than 11,000 properties and aim to deliver 112,000 new homes across New South Wales over five years.
New Planning Controls and Design Standards
In September 2025, Northern Beaches Council amended its Manly, Warringah, and Pittwater Development Control Plans to preserve local design quality, heritage, and sustainability standards. The updates ensure that new developments reflect neighbourhood character despite broader state planning reforms.
These adjustments maintain requirements for landscaping, site layout, and setbacks while aligning with the new policy’s density goals.
Impact on Dee Why and Other Centres
In Dee Why, medium-density housing such as townhouses, terraces, and apartments will be permitted within walking distance of the town centre. Projects within 800 metres can reach four storeys, while those within 400 metres may rise to six storeys or 24 metres.
This mirrors similar developments in Mona Vale and Forestville, both designated for greater housing diversity under the same policy.
Infrastructure and Community Concerns
Some community representatives have raised concerns about the lack of infrastructure improvements to support population growth. The Northern Beaches’ population is expected to reach 288,000 by 2036, creating demand for around 12,000 new homes and added pressure on transport and public services.
The council continues to seek a balance between growth and maintaining liveability within established suburbs.
Next Steps for Planning in Dee Why
Northern Beaches Council is preparing to release its amended Development Control Plans for public consultation. These plans will help guide future development applications under the Low and Mid-Rise Housing Policy, shaping how new housing projects in Dee Why and other centres proceed in coming years.
