Victoria minimum garden area: test the footprint before you buy

CHECK GARDEN AREA BEFORE TRUSTING THE FOOTPRINTVictoria: pre-purchase garden area test

A block can look generous and still leave too little room for the development you want. Before paying for a site on the assumption that another dwelling fits behind the house, ask a narrower question: after reserving the required garden area, can the proposed buildings, driveway and parking actually work together?

This is a footprint test, not a promise about dwelling numbers. Run it before you settle on a purchase price or spend money refining an attractive floor plan.

First establish whether the requirement applies

The General Residential Zone and Neighbourhood Residential Zone contain minimum garden area requirements for constructing or extending a dwelling, small second dwelling or residential building. Their development tables require 25% for lots of 400–500 square metres, 30% for lots above 500 up to 650 square metres, and 35% for lots above 650 square metres. Exactly 500 sits in the first band; exactly 650 sits in the second. Check clause 32.08-4 and clause 32.09-4.

Start with the actual zone and schedule, not a neighbouring property's approval or a sales description. Do not transfer this table to every residential zone.

Count qualifying area, not everything outside

Under the clause 73.01 garden area definition, qualifying area has a minimum dimension of one metre. Driveways and areas set aside for car parking are excluded. A strip beside the house does not automatically count merely because it is open to the sky.

Equally, garden area does not mean planted soil only. The definition allows specified structures and works, including pergolas and unroofed patios or decks below 800 millimetres in height. Its exceptions have conditions; ask the designer to identify each inclusion rather than colouring every outdoor surface green. A roofed alfresco area forming part of the dwelling is not the same as a qualifying unroofed patio, as PPN84 explains.

The trap: passing one measure does not pass the others

Minimum garden area, landscaping and site coverage answer different questions. Clause 55.02-5 addresses area covered by buildings, while clause 55.02-7 separately addresses tree canopy. A garden-area tally is not a planting plan, a permeability calculation or proof that the building footprint is acceptable.

PPN84 describes minimum garden area as a separate mandatory requirement that cannot be reduced. Where it applies, do not base the purchase on persuading someone to accept a smaller percentage later.

Run a simple pre-purchase site test

For an illustrative 700-square-metre lot where the 35% requirement applies, the minimum garden area is 245 square metres. That leaves 455 square metres outside the garden allocation, not 455 square metres of approved building footprint. Driveway and parking also need room outside that allocation. This is arithmetic, not an assessed development proposal.

1. Confirm the starting lot. Give the town planner the address, title information and intended development sequence. Ask which lot area and requirement apply.
2. Draw the exclusions. Have the designer mark retained and proposed buildings, roofed outdoor areas, access and parking on a dimensioned sketch.
3. Measure the remainder honestly. Identify qualifying garden areas, dimensions and conditional inclusions without double-counting.
4. Test a fallback. Compare your preferred layout with a smaller footprint before relying on the preferred dwelling count.

Ask for the marked-up sketch and area schedule together. A percentage without a drawing hides where the space is supposed to come from.

Also compare the shape of the remaining spaces. Ask whether making room for access forces a narrower dwelling, a different entry or a smaller outdoor area than your intended buyer would accept. Those are design and product questions to investigate now, not assumptions to leave until after purchase.

Do not assume small lots or old houses are exempt

The development table starts at 400 square metres, but subdivision is a separate trigger. Under clause 32.09-3, creating a vacant lot below 400 square metres capable of dwelling or residential-building development generally requires 25% garden area on that new lot, with specified plan and development-permit exceptions. The GRZ has corresponding provisions.

A GRZ schedule can switch off the development requirement; the NRZ does not contain that same schedule option. Other exceptions concern designated medium-density sites under specified approved plans, or alterations/extensions of buildings that were non-compliant at the relevant historical date. Transitional provisions also need checking. None means that every old house, small lot or site near transport is exempt.

Let the result change the buying decision

If the sketch works only by counting parking as garden area, pause. Ask for a revised layout and update feasibility for the accommodation it actually supports, including redesign costs. Consider whether retaining the existing house still makes sense. Do not preserve an unsupported purchase price by assuming the shortfall will disappear.

You are not expected to solve this yourself. A town planner should confirm the current site-specific rule and evidence for any exemption; the designer should demonstrate the measured response. The useful pre-purchase outcome is a defensible layout assumption, not a percentage copied into a spreadsheet.

Key takeaway: reserve qualifying garden area before trusting the footprint. What part of your preferred layout would need to change if the planner rejects one of your counting assumptions?
