Can My Property Be Subdivided? Understanding Lot Size and Zoning in NSW

If you’re a property owner in the Hornsby Shire area wondering, “Can my property be subdivided?”,  you’re not alone. With rising interest in property development across Sydney, many homeowners are exploring the potential to subdivide and unlock extra value in their land.

But before you start drawing up plans, it’s essential to understand the lot size requirements and zoning rules that apply, especially those set by Hornsby Council.

What is Property Subdivision?

Subdivision is the process of dividing one property into two or more lots. This might be to sell off part of the land, build a second dwelling (like a duplex or granny flat), or prepare for a future development project. In areas like Hornsby, subdivision is becoming more common due to increasing demand for housing and larger lot sizes compared to inner-city areas.
 

Zoning and Land Use in Hornsby Shire

In NSW, zoning is determined by your local council and guided by the NSW Planning Portal. In Hornsby Shire, residential zones such as R2 Low Density Residential or R3 Medium Density Residential are most relevant for subdivision.

Each zoning type outlines what you can and can’t do with your land. For instance, R2 zoning in Hornsby may allow for dual occupancy (two dwellings on one lot), but subdivision approval depends on factors like lot size, access, and council guidelines.

To check your zoning, you can visit the Hornsby Council zoning map or use the NSW Planning Portal.
 

Minimum Lot Size for Subdivision in Hornsby

One of the most important requirements for subdivision is meeting the minimum lot size. In Hornsby Shire, this can vary depending on the zoning and location of your property. For example:

• R2 zoned land typically requires a minimum lot size of 500-600 sqm per lot for a subdivision to be considered.

• For battle-axe or rear lots, extra requirements may apply regarding access and lot shape.

• In heritage areas or environmentally sensitive zones, stricter rules may apply.

Always consult the Hornsby Council Local Environmental Plan (LEP) or speak to a local builder or planner to confirm the exact lot size requirements for your specific property.

The DA Process and Subdivision Approval

To subdivide in Hornsby, you’ll need to lodge a Development Application (DA) with the council. This includes submitting detailed plans, engineering reports, and demonstrating that the subdivision meets all planning controls.

The DA approval process in Hornsby can take several weeks to months, depending on complexity, zoning, and feedback from neighbours or council staff.
 

Is Subdivision Right for Your Property?

Whether you’re in Hornsby, Asquith, Mount Colah, Thornleigh, or surrounding suburbs, the key to a successful subdivision is understanding what’s possible before you start.

A feasibility study, including a zoning check, minimum lot size assessment, and potential development yield, can save time and money. An experienced builder or subdivision specialist familiar with Hornsby Council requirements is invaluable.
