What the check covers
BAL assessment, management plan, asset protection zone
Septic or treatment system approval where there is no sewer
Clearing permits before the excavator arrives
Legal access, crossovers and fire appliance requirements
Easements, covenants and notifications that limit where you build
Scheme water, power, telecommunications or off-grid
Not another project management app
Most construction software assumes you already know that engineering comes before permits, and permits before earthworks. OwnerBuild OS is built the other way around: the property and your intentions drive a rules engine, the rules produce requirements, and the requirements produce your plan and your evidence trail.
Western Australia is the first complete jurisdiction. The rules are dated, sourced and versioned, so the app uses the rule that applied on the day that matters — not whatever was true when an article was written.
