Two registers, side by side

What is proposed here versus what is approved. These are separate government registers that nobody publishes together: the NSW Planning Portal records what people apply to build, the ABS records what is actually approved. Over the last 12 months the ABS recorded 48 dwellings approved in Mosman Municipal Council worth $225M. The application pipeline is running at about 4.32× that rate. Substantially more is being proposed than approved.

What this council page tells you

Use the evidence in context. Applications show what has been proposed, not what has been approved or built. The figures above bring the NSW Planning Portal application feed together with the ABS approvals register and heritage data where a reliable council match exists.

Evidence boundary

Evidence found2,007 applications since 2019; 1,370 proposed homes; 48 dwellings approved in the current ABS comparison period.
Source coverageNSW Planning Portal Online DA, with ABS Building Approvals and NSW heritage registers where matched. Application data checked through 22 Aug 2026.
What this meansThis is the complete evidence currently loaded for this named council from the stated source universe.
What this does not meanZero or missing values do not prove no activity outside those sources. An application is not an approval or a completed project, and the NSW feed does not publish applicant, owner, architect or developer identity.

Applications: NSW Planning Portal Online DA API (CC-BY). Approvals: ABS Building Approvals by LGA (CC-BY 4.0). Decision time is measured from lodgement to determination on the 1,638 applications carrying both dates. Cost of works is the applicant's own estimate.
