Pre-Purchase Planning Advice: Know What You Can Build Before You Buy
Buying land or property is one of the biggest financial decisions most people make. Whether you are purchasing a first home with plans to extend, a rural block for a new dwelling, a shopfront for a new business, or a development site for subdivision, the price you pay is only worth it if the property can actually deliver what you have in mind.
That is where pre-purchase planning advice comes in. A preliminary planning review, carried out before you sign, gives you a clear picture of what the planning rules allow on a site, what might stand in the way, and what the approval pathway is likely to look like.
At PlanBE, we have completed preliminary planning reviews for clients across NSW and ACT for many years, covering residential, commercial, small scale and large scale developments. In our experience, the buyers who get advice early are the ones who avoid unpleasant surprises later.
What Is Pre-Purchase Planning Advice?
Pre-purchase planning advice is a review of a property from a town planning perspective, completed before you exchange contracts. It looks at the planning controls and site constraints that apply to the land and tests them against what you want to do with it.
The goal is simple: to answer the question "can I do what I want to do here?" before you are financially committed, rather than discovering the answer when a development application is already underway.
Why the Contract Documents Are Not Enough
In NSW, a contract for the sale of land comes with a planning certificate issued under section 10.7 of the Environmental Planning and Assessment Act 1979. It is a useful document. It confirms the zoning and lists the planning instruments and certain hazards that apply to the land.
What it does not do is interpret those controls for your particular plans. A planning certificate will tell you which Local Environmental Plan applies, but not whether your proposed second dwelling meets the minimum lot size, whether your intended business use is permissible in the zone, or how a bushfire or flood affectation will shape the design and cost of a future build.
Reading these documents in isolation can give buyers a false sense of certainty. Pre-purchase planning advice fills that gap.
What a Preliminary Planning Review Looks At
Every site is different, and the scope of a review depends on what you are hoping to achieve. A typical preliminary planning review considers:
Zoning and permissibility: whether your intended use is permitted in the zone, permitted with consent, or prohibited
Development standards: controls in the Local Environmental Plan such as minimum lot size, height of buildings and floor space ratio
Development Control Plan requirements: setbacks, site coverage, parking, landscaping and design controls set by council
Site constraints and hazards: bushfire prone land, flooding, heritage, biodiversity, contamination and other affectations
Title matters: easements, covenants and restrictions that may limit how the land can be used
Existing approvals and uses: what is currently approved on the site and whether existing structures or uses are lawful
Approval pathway: whether the proposal may fall under exempt or complying development, or will need a development application
Likely reports and costs: the specialist consultant reports a future application may need, such as a Bushfire Assessment, traffic report or Statement of Environmental Effects
The result is a clear, practical summary of the opportunities and risks, so you can make your decision with confidence or negotiate with better information.
Pre-Purchase Planning Advice in the ACT: Key Differences
PlanBE works on both sides of the border, and buyers in Canberra and the surrounding ACT face a different set of rules to those in NSW.
The questions are the same (can I do what I want to do here?), but the answers come from different places.
Leasehold land and the Crown lease. Land in the ACT is held under a Crown lease rather than freehold title. The lease sets out the purposes the land can be used for, and land and buildings can only be used for a purpose the lease authorises. Some leases also limit the number of dwellings permitted on the block. Reviewing the Crown lease purpose clause is one of the most important steps before buying in the ACT, particularly if you are planning a second dwelling, a business use or redevelopment.
Lease variations and charges. If your plans go beyond what the lease allows, a lease variation may be needed. This usually forms part of a development application and, depending on the change, may attract a Lease Variation Charge based on the added value the variation brings. Knowing this before you buy can make a significant difference to your budget and feasibility.
The Territory Plan. Development in the ACT is guided by the Territory Plan under the Planning Act 2023. Zone policies set out what can be developed in each zone, while district policies add requirements specific to each district and can permit or prohibit particular uses on specific blocks. Technical specifications and design guides sit alongside these policies to help show how a proposal can meet the intended outcomes.
Exempt development and assessment pathways. Some works, including certain single dwelling housing, may not need development approval if they meet the relevant exemption criteria and development controls. Other proposals will need a development application assessed against the Territory Plan's policy outcomes.
Our Senior Planner has worked within the ACT Government and managed construction sites across Canberra, bringing first-hand understanding of how the ACT system works in practice. Whether you are buying in Canberra, Queanbeyan or the surrounding region, we can review the property against the rules that actually apply.
Who Benefits From Pre-Purchase Planning Advice?
Home buyers wanting to extend, add a granny flat or secondary dwelling, build a shed or pool, or knock down and rebuild.
Rural and lifestyle buyers planning to build a dwelling on vacant land, where questions of dwelling entitlement, bushfire and access often come into play.
Investors considering dual occupancy, secondary dwellings or subdivision to add value to a property.
Business owners and commercial buyers looking at a premises for a new use, where a change of use may require development consent and compliance upgrades.
Developers assessing the yield and feasibility of larger sites, including whether a rezoning or more complex approval pathway may be required.
When Should You Get Pre-Purchase Planning Advice?
The best time is before you exchange contracts. A preliminary review is far less expensive than buying a property that cannot be used the way you intended, or discovering a constraint that adds significant cost to your project.
If you are already close to exchange, speak with your conveyancer or solicitor about timing and contract conditions, and let us know your deadline so we can prioritise the review.
Experience Across Residential, Commercial and Development Sites
PlanBE has completed preliminary planning reviews and pre-purchase advice for a wide range of clients over the years, from single dwellings and rural blocks through to commercial premises and larger multi-lot development sites. Working across regional NSW, the ACT and Greater Sydney means we understand how planning controls and council expectations vary from one area to the next.
That breadth of experience helps us spot the issues that matter early, and give clear, practical advice on what a site can realistically achieve.
