Rules from MBRC Planning Scheme 2016
Do you need council approval for a granny flat or secondary dwelling in Moreton Bay?
Queensland's Planning Act 2016 sorts development into three assessment categories: accepted development (no development application needed if you meet the stated requirements), code assessable (a DA assessed against the planning scheme's codes, no public notification), and impact assessable (a DA with public notification and third-party appeal rights). Which category applies to your project is set by MBRC Planning Scheme 2016 — and it depends on your zone, any precinct that applies, and the overlays on your lot.
Under MBRC Planning Scheme 2016, a secondary dwelling (granny flat) is contemplated in 8 of the 16 zones we track for Moreton Bay, including Emerging Community, General Residential, Low Density Residential, Medium Density Residential and 4 other zones, and not in 8 others. Where a granny flat complies with the scheme's requirements for the zone — size, siting and the applicable codes — it can often proceed without a planning application (building approval is still required). Fall outside those requirements, or pick up an overlay trigger, and a development application is needed.
Queensland also allows secondary dwellings to be rented separately from the main house (a state-wide change from 2022), which removed the old "household member" restriction in most schemes. The zone table below shows where Moreton Bay's scheme contemplates a secondary dwelling — but lot size, flood and character overlays, and precinct mapping decide the answer for a specific address.
None of this is answerable with certainty at council level — the pathway for your project is set by your lot's zone, precinct and overlays together. A free Casa block check reads those for your exact address in seconds.
Granny flat rules by zone in Moreton Bay
Zone-level provisions from MBRC Planning Scheme 2016. Zone rules are the starting point — precinct mapping and overlays can tighten them for individual lots.
| Zone | Secondary dwelling | Max height | Notes |
|---|---|---|---|
| Emerging Community | Yes | 9.5 m | MBRC 2016 v12 Part 6.2.5 — future urban transition land. Holding zone; AOs match GR until structure plan adopted. Often rezoned to NA/GR once trunk infrastructure delivered. |
| General Residential | Yes | 8.5 m | MBRC 2016 v12 Part 6.2.6 — the dominant Moreton Bay residential zone (~130k properties). 400 m² standard lot, 12.5 m frontage, 8.5 m / 2 storey envelope, 50% site cover. Dual-occ code-assessable on lots ≥600 m². Precinct sub-categories (Suburban Neighbourhood, Urban Neighbourhood, Next Generation) refine AOs by precinct; these are the default zone-wide values. |
| Low Density Residential | Yes | 8.5 m | — |
| Medium Density Residential | Yes | 11 m | — |
| Next Generation Neighbourhood | Yes | 8.5 m | MBRC 2016 v12 Part 6.2.9 — masterplanned greenfield (Caboolture West, North Harbour, The Mill). Smaller lots (300 m² standard), tighter setbacks to support compact form. Most lot/setback AOs deferred to the relevant Local Plan / structure plan; these are the conservative zone-wide defaults. needs_verification:precinct_overrides |
| Rural Residential | Yes | 8.5 m | MBRC 2016 v12 Part 6.2.11 — 4,000 m² (1 acre) standard rural-res lot. Single dwelling + secondary dwelling permitted. Subdivision generally not supported (zone resists fragmentation). |
| Rural | Yes | 8.5 m | MBRC 2016 v12 Part 6.2.12 — 100 ha standard rural lot (per State Planning Policy for agriculture). Dwellings limited to one per lot. Subdivision strongly resisted. |
| Township | Yes | 8.5 m | MBRC 2016 v12 Part 6.2.14 — small rural townships (Dayboro, Mt Mee, Mt Glorious). 600 m² standard lot. Modest density to retain village character. |
| Centre | No | 22 m | MBRC 2016 v12 Part 6.2.2 — covers Major / District / Local / Neighbourhood centre precincts. Default height 22 m / 6 storeys for Major (Strathpine, Morayfield); lower for Local / Neighbourhood (typically 12 m / 3 storeys). Use the relevant Centre Hierarchy Local Plan for precinct-specific AOs. needs_verification:precinct_height |
| Community Facilities | No | 15 m | MBRC 2016 v12 Part 6.2.3 — schools, hospitals, places of worship, community halls. Height typically 15m / 3 storeys (hospitals up to 22m via precinct overlay). Lot/cover/setbacks use-specific. needs_verification:lot_frontage_cover_setbacks |
| Extractive Industry | No | 15 m | MBRC 2016 v12 Part 6.2.4 — quarries, sand extraction. Large lots with substantial buffer setbacks. Operates under Key Resource Area overlay. Residential not permitted. |
| Environmental Management and Conservation | No | — | MBRC 2016 v12 — koala habitat, riparian corridors, conservation reserves. Development heavily restricted; impact-assessable on a case-by-case basis. AOs deliberately NULL. |
| High Density Residential | No | 15 m | — |
| Industry | No | 15 m | MBRC 2016 v12 Part 6.2.7 — Brendale, Narangba, Caboolture industrial areas. Combines low + medium impact industry. Residential not permitted. needs_verification:precinct_overrides |
| Limited Development (Constrained Land) | No | — | MBRC 2016 v12 Part 6.2.8 — flood / slope / ecology constrained land. No zone-wide AO for lot/height/cover. All development impact-assessable against site-specific constraints. AOs deliberately NULL — do not infer permissive defaults. |
| Recreation and Open Space | No | 8.5 m | MBRC 2016 v12 Part 6.2.10 — parks, sport fields, foreshore reserves. Very limited built form (caretaker / amenities only). needs_verification:lot_frontage_setbacks |
“—” means the value is not recorded in our rules dataset, not that no rule exists. Always confirm against the current planning scheme before relying on a figure.
How granny flat and secondary dwelling applications have fared in Moreton Bay
Across 482 decided secondary dwelling (granny flat) applications recorded against Moreton Bay council, 478 were approved — an approval rate of 99%. That reflects a strong track record for this kind of proposal. These are real, decided applications assessed by the council, not estimates or modelling.
The median time from lodgement to decision was 43 days (measured across the 482 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 for the specific site.
We do not hold enough charged decision notices in this cohort to publish a median infrastructure charge for Moreton Bay. As a statutory ceiling, Queensland caps adopted charges at $36,670.70 per three-or-more-bedroom dwelling or lot (2025–26 indexed) — an upper bound, not an estimate for your project.

Granny flat in Moreton Bay: common questions
Do I need council approval for a granny flat or secondary dwelling in Moreton Bay?
It depends on your lot's zone, precinct and overlays under MBRC Planning Scheme 2016. Queensland sorts development into accepted (no DA if requirements are met), code assessable (DA without public notification) and impact assessable (DA with public notification). Some compliant proposals of this type proceed without a planning application, others need a full DA. The only reliable way to know your pathway is to check your specific address.
Which zones allow granny flat and secondary dwelling development in Moreton Bay?
Under MBRC Planning Scheme 2016, granny flat and secondary dwelling development is contemplated in Emerging Community, General Residential, Low Density Residential, Medium Density Residential, Next Generation Neighbourhood, Rural Residential and 2 other zones. Zone permission is the starting point, not the answer: precinct mapping and overlays can restrict individual lots within a supportive zone.
What is the approval rate for granny flat or secondary dwelling applications in Moreton Bay?
99% of the 482 decided secondary dwelling (granny flat) applications recorded against Moreton Bay council were approved (median 43 days to decision). Figures are indicative, derived from decided council records; past decisions do not guarantee future outcomes.
How long does granny flat or secondary dwelling approval take in Moreton Bay?
The median time from lodgement to decision across the 482 dated applications in this cohort was 43 days. Individual applications vary with information requests, referrals and the assessment pathway that applies to the site.
About this guide
Zone rules on this page are drawn from MBRC Planning Scheme 2016 as recorded in our dataset, and application statistics from decided development applications recorded against Moreton Bay council, current as of 26 July 2026. Planning schemes are amended over time and precincts, neighbourhood plans and overlays can vary the rules for individual lots. Past decisions describe how comparable proposals have fared — they do not guarantee, and cannot predict, the outcome of any future application.
