Is your block larger than the typical minimum for a second dwelling or subdivision in your council area?Fast-track (CDC) granny flats in NSW need a minimum lot of 450 sqm; the comparable minimum in Victoria is 300 sqm.

Does your block have street frontage or practical access for a second dwelling or new lot?Battle-axe access, corner lots and rear lanes each carry their own requirements.

Is the land reasonably flat, or gently sloping?Steep sites can still work, but cut, fill, retaining and stormwater add cost and complexity.

Is the backyard free of easements, sewer mains and drainage infrastructure?Check your title plan and utility mapping, not your memory.

Does your zone permit a secondary dwelling, dual occupancy or subdivision?Check the land use table for your zone on your state's planning portal.

Is the property free of heritage listings and conservation or character overlays?Area-based controls count, not just individual listings.

Is the property clear of flood and bushfire mapping?Hazard mapping does not always end a project, but it always shapes one.

Is the title free of restrictive covenants limiting dwellings or subdivision?Single dwelling covenants can override favourable zoning, especially in Victoria.

Can you provide the required parking without demolishing half the site?Parking after construction must generally match what existed before, and each dwelling needs its own private open space.

Are existing structures on the property all approved?Unapproved works complicate every new application on the site.

Is significant vegetation clear of your likely building area?Protected trees and environmental overlays can sterilise the exact corner you need.

Do comparable projects exist in your immediate area under the current rules?Recent approvals nearby suggest a supportive assessment environment. Old examples prove nothing.

“Not sure” answers are your due diligence list — they matter as much as the total.

The three bands

Notice something? Every band ends the same way

A self-assessment can only tell you which questions matter. It cannot assess your specific site against the controls — and that is the part your project actually depends on.

18–24Strong potential, verify and move

Your risk is not whether the site has potential, but leaving value on the table or tripping on a detail.

10–17Possible, but the "not sures" decide it

The most common result, and the most dangerous one to act on alone. Your project turns on one or two unresolved constraints.

0–9Significant constraints, get clarity first

Multiple flags does not always mean no. It means the pathway, if there is one, is narrow and needs professional navigation.

Before you spend on design

A planner's answer costs less than a set of drawings you can't use

A Preliminary Planning Report assesses your site against the actual controls: what it supports, which pathway is available, and how to get the most out of it. Delivered in 48 to 72 hours from A$1,100.

What owners ask us

No. The score tells you which questions matter for your site and where the risk sits. Approval depends on your specific proposal assessed against the actual controls, which is what a planner does.
