Do I need approval for a granny flat in the low density residential zone in Toowoomba?

No planning approval needed. Conditions: a granny flat is part of a dwelling house; accepted if the site is 450m² or more, not a hatchet lot and not within an approved plan of development listed in Schedule 7 (otherwise accepted subject to requirements; code assessable if those requirements aren't met). If those aren't met: accepted if you meet the requirements. (Source: Toowoomba Regional Planning Scheme 2012 (Version 29), Table 5.5:1.)

Granny flats in Toowoomba — do you need approval?

Toowoomba Regional Council's planning scheme — the Toowoomba Regional Planning Scheme 2012 (Version 29) — decides whether a granny flat needs a development application, and the answer depends on the zone your property is in. Below is what its table of assessment says for each zone; or check your own address.

In a low density residential zone

No planning approval needed. A granny flat counts as part of a dwelling house, which in the Low Density Residential zone needs no development application on a lot of 450m² or more that isn't a hatchet lot or in a listed plan of development; otherwise it must meet the listed design requirements, or a code assessable application is needed.

Overlays that change the answer

Airport Environs Overlay. Within the ANEF 20 contour and above, a dwelling house, dual occupancy or multiple dwelling that would be accepted (or accepted subject to requirements) in the zone becomes code assessable against the Airport Environs Overlay Code. (Table 5.10:1)
Bushfire Hazard Overlay. Accepted development not otherwise listed becomes accepted subject to requirements — it must meet the Bushfire Hazard Overlay Code's acceptable outcomes or becomes code assessable. (Table 5.10:1)
Extractive Resources Overlay. Within an extractive resource separation area or 100m of a designated haulage route, a dwelling house, dual occupancy or multiple dwelling that would be accepted (or accepted subject to requirements) becomes code assessable against the Extractive Resources Overlay Code. (Table 5.10:1)
Flood Hazard Overlay. A dwelling house or dual occupancy must meet the Flood Hazard Overlay Code's acceptable outcomes (accepted subject to requirements), becoming code assessable if it doesn't or if in the FR3/FR4 flood risk areas or a Flood Management Precinct; a vulnerable use in a Vulnerable Uses Restriction Area is impact assessable. (Table 5.10:1)
Landslide Hazard Overlay. Accepted subject to requirements and assessable development must also meet the Landslide Hazard Overlay Code's acceptable outcomes (or becomes code assessable). (Table 5.10:1)
Neighbourhood Character Overlay. A dwelling house (as a material change of use) becomes code assessable; a dual occupancy or multiple dwelling becomes impact assessable, as does reconfiguring a lot that creates a hatchet lot or a lot under 450m². (Table 5.10:1)

Worth knowing in Toowoomba

Toowoomba Regional Planning Scheme 2012 (Version 29), Part 5. A material change of use is impact assessable unless the table says otherwise or the use isn't listed; reconfiguring a lot is code assessable unless the tables say otherwise; building work and operational work are accepted unless the tables say otherwise (section 5.3.2). Accepted development subject to requirements that doesn't meet the listed acceptable outcomes becomes (limited) code assessable (section 5.3.3). Where land is in more than one zone, local plan or overlay the highest category applies, but a local plan overrides the zone and an overlay overrides both (section 5.3.2). Schedule 6 of the Planning Regulation 2017 overrides the scheme (e.g. a dwelling house, community residence or home-based business can be accepted regardless). Building work: the accepted-subject-to-requirements part of Table 5.7:1 was replaced by Temporary Local Planning Instrument 01/2026 (Table of Assessment for Building Work) from 16 February 2026, which isn't reproduced in the source — the shed, extension, pool and fence answers follow the pre-TLPI 'All other building work → applicable zone code' row and should be checked against the TLPI. Excavating or filling that changes ground level by more than 1m (other than for a pool outside the Landslide Hazard Overlay) is code assessable. A building approval under the Building Act is still needed in all cases. Granny flats follow the Dwelling House row (a dwelling house includes a secondary dwelling); dwelling houses in the Low Density and Low-medium Density Residential zones are accepted on lots of 450m² or more that aren't hatchet lots or in a Schedule 7 plan of development, otherwise accepted subject to the Small Lot Housing Design Code or Medium Density Residential Code. Precincts change answers in many zones: Low Density Residential (Clifford Park Stables, Park Residential — larger minimum lots); Low-medium Density Residential (Hospital Support, Urban Consolidation, Regional/Urban/Office Residential — shop, café and office rules); Specialised Centre (Defence Facilities — houses, dual occupancy and units; Specialist Retail Centre; Toowoomba Airport; Queensland Government Research Facility); Community Facilities (Education, Higher Education, Hospital, Government, Other Community Purposes); Mixed Use (West Creek and City South Bulky Goods/Service Industry — some centre uses excluded); Township (Flood Management Precinct makes a house or dual occupancy code assessable); Rural Residential and Rural (minimum lot size by precinct); Industry zones (Wellcamp, General Industry, Transport and Warehousing, Intermodal, Heavy Industry, Quarry). Local plans (section 5.9): Highfields, Meringandan and Meringandan West (Major Centre Medium Density Residential Precinct — dwelling house and dual occupancy impact; Town Centre Frame — department store/supermarket impact), Glenvale (no category changes) and Charlton Wellcamp Enterprise Area (many centre uses in industry precincts become impact; Local Centre Commercial Centre Precinct — shop/office code to 250m², multiple dwelling impact). Overlays with no category change (benchmark only): Agricultural Land, Environmental Significance, Scenic Amenity (MCU), Regional Infrastructure Corridors and Substations (MCU), Water Resource Catchments.
