What the numbers say about Tanah Merah
Across 39 decided dual-occupancy and multi-unit dwelling applications on Tanah Merah properties, 35 were approved — an approval rate of 90%. That reflects a solid, though not automatic, track record for this kind of proposal. These are real, decided applications assessed by the Logan council, not estimates or modelling.
The median time from lodgement to decision was 35 days (measured across the 37 applications in this cohort with both dates recorded). That is a comparatively fast assessment turnaround. Individual applications vary widely with information requests, referrals and the assessment pathway that applies to the specific site.
Based on 39 decided applications in Logan, these figures describe how comparable proposals have actually fared — but every site is different. Zoning, overlays, lot dimensions and the assessment pathway for your specific parcel decide what is realistic for your project.

About this data
These statistics summarise decided development applications recorded against Tanah Merah properties in Logan council records, current as of 2 July 2026. Past decisions describe how comparable proposals have fared — they do not guarantee, and cannot predict, the outcome of any future application. Council assesses every application on its merits against the planning scheme that applies at the time. This page is general information, not planning or legal advice: what is achievable on a specific site depends on its zoning, overlays, lot dimensions and assessment pathway.
