Use parcel maps as a starting point
The Department of Lands LandsMaps service helps locate parcel information. Compare it with documents and a site inspection. Online map coordinates do not replace a boundary survey for construction.
Inspect access, road connections, ground levels and surrounding conditions. Resolve differences between paperwork and the site before selecting a plan or concluding a purchase.
Appraisal is different from a sale price
The Treasury service provides official appraisal information. A listing displays an asking price. Neither alone proves the price achieved in a completed transaction.
Compare like units and like area definitions. Keep land area separate from building floor area. A price per square wah of land is not comparable with a price per square metre of interior space without understanding the basis.
Check applicable planning requirements
DPT LandusePlan is a starting point for land-use plans and associated requirements. One map layer does not establish that a specific project is permitted.
Give the plot details and intended building use to the relevant authority or professional. Record the source, date and unresolved questions for each decision.
