A secondary dwelling may create flexible accommodation or an additional rental outcome, but the opportunity should never be assumed from block size alone. The site, existing home, planning controls, building requirements, services, finance and rental strategy all need to be tested before purchase.
Understand Victoria’s secondary-dwelling pathway
Victoria provides a planning-permit exemption for eligible small second homes that meet defined requirements, including size and siting conditions. A building permit is still required, and other planning overlays or site constraints may affect the proposal.
Rules and project circumstances can change. Confirm the current requirements with the responsible council and appropriately qualified planning, building and design professionals before relying on an exemption.
Assess whether the site really works
- Usable site area after allowing for the existing home and required setbacks
- Access for construction, occupants, parking and future maintenance
- Location of drainage, sewer, utilities, easements and significant vegetation
- Slope, overlooking, private open space and the relationship between dwellings
- Bushfire, flooding, heritage or other overlays and constraints
Model the complete project
The feasibility should include design, approvals, services, site works, access, contingencies, holding costs and realistic rental assumptions—not only the advertised building price.
A licensed finance partner should confirm how the purchase and proposed works may be assessed. D&J can provide rental insight and coordinate an introduction, but does not provide personal credit advice.
Plan the management outcome before buying
Consider privacy, utility arrangements, maintenance responsibility, addresses, access and the likely renter market for each dwelling. A pre-purchase management review can help identify whether the finished property is likely to operate as intended.
The strongest opportunity is one that works across Find, Fund, Manage and Grow—not simply a block that appears large enough on a map.
