Can I claim renovations done by the previous owner?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Yes, you may be able to claim capital works deductions for eligible renovations completed by a previous owner. A quantity surveyor can estimate the construction cost where invoices are not available.

Previous owner renovations are one of the biggest missed depreciation opportunities.

Examples include:

Kitchen renovations
Bathroom upgrades
Extensions
Decks
Roofing
Tiling
Structural improvements
Built-in wardrobes
Outdoor areas
Common property upgrades

Even if you did not pay for the renovation, you may be able to claim the remaining capital works deduction if the works qualify.

A QS can estimate:

Approximate cost
Year of works
Construction type
Eligible capital works component
Remaining claim period
