What the numbers say about Banyo

Across 12 decided dual-occupancy and multi-unit dwelling applications on Banyo properties, 10 were approved — an approval rate of 83%. That reflects a solid, though not automatic, track record for this kind of proposal. These are real, decided applications assessed by the Brisbane council, not estimates or modelling.

The median time from lodgement to decision was 220 days (measured across the 12 applications in this cohort with both dates recorded). That is a longer-than-typical assessment timeframe — worth building into your project programme. Individual applications vary widely with information requests, referrals and the assessment pathway that applies to the specific site.

Based on 12 decided applications in Brisbane, 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 Banyo properties in Brisbane 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.
