Can You Build a Granny Flat on Your Property ? Here’s How to Check

Adding a granny flat to your property is one of the smartest ways to unlock extra income, increase property value, and create flexible living options for family.

But here’s the catch: not every block is eligible for a granny flat. Council rules, zoning, Lot size, and even access points can affect whether you can build.

So, how do you know if your property is granny-flat ready ?

✅ Common Requirements for Granny Flats in NSW

Before you spend time and money with a builder, here are the general guidelines:

  • Minimum Lot Size: Usually 450m² or larger (differs in other States)
  • Zoning: Most residential zones (R2, R3, R4) are eligible
  • Existing Dwelling: You must already have a main house on the property
  • Setbacks: Enough space from boundaries, easements, and services
  • Access: Suitable side or rear access for construction

Tip: Every council is different – which is why an expert check saves you from guesswork. Note: most granny flat approvals can be fast-tracked under a Complying Development Certification process.. More Details about the Complying Development process can be found here.
