Can you legally add a bedroom to this property?
Improve the performance of the property you own.
Best for: Owners with an unused study, sunroom or oversized space
Converting a study, den, or large living area into a "bedroom" can lift achievable rent, but only if it's actually a legal bedroom. Advertising a room as a bedroom that doesn't meet building code requirements (window size, ceiling height, egress) creates risk without the rent benefit holding up to scrutiny.
What to check
- Whether the room has a compliant window for natural light and emergency egress
- Minimum room size and ceiling height requirements in your state
- Whether any wall or door changes needed require council approval
- Smoke alarm and safety switch compliance for the additional room
Who can help
Building inspector or certifier
Whether the room meets bedroom requirements, and what work would bring it up to standard.
Quantity surveyor
The cost of any works needed.
Local council
Approval requirements for the changes.

Copy this question and put it to a building inspector or certifier.
What happens next
If the room already qualifies, you may be able to re-advertise the property's bedroom count immediately at no cost. If it needs work, get a firm cost estimate and compare it against the likely rent uplift before proceeding, the same discipline as any renovation decision.

THE HOLD QUESTION
Is that "third bedroom" you're about to advertise actually one, or is it a study wearing a bedroom's price tag?
