Building a Granny Flat in Perth

Turn your backyard into rental income.

If you’ve got unused yard space, you’re sitting on an income opportunity. Perth’s rental market is tight, demand is high, and a well-built granny flat on your existing block can generate 15 to 18% extra yield on land you already own.

Assure is the only Perth agency that builds your granny flat and manages it afterwards. Design, council approvals, construction, tenant placement, ongoing management — one team handles all of it. You deal with the same people from the first phone call to your first rent cheque.


What our Build & Manage package covers

  • Obligation-free site assessment and council approval advice
  • Custom floor plan design to suit your block and budget
  • Full construction management with trusted local builders
  • Tenant placement through our in-house property management team
  • Ongoing property management after handover — we don’t disappear at the keys

How quickly does it start earning?

We prioritise fast builds and have our leasing team working well before construction finishes. Several of our clients had tenants locked in before they had the keys. Your backyard will pay for itself and more.

Tris and Jon were fantastic and handled absolutely everything — from my unused backyard to a new income. Before construction was even completed their leasing team had already secured a great tenant paying rent that exceeded our expectations. We had no idea it would be this straightforward.
