Granny Flats Redlands – Redland City Council Rules, Approvals & Site Requirements
If you're researching granny flats in Redlands, the first step is understanding what your particular property can support. Redland City Council rules, Amenity and Aesthetics requirements, size thresholds, setbacks, overlays, infrastructure and approval pathways can all affect the design.
We specialise in custom on-site granny flats and detached extensions, designed around the property, the people who will use the space and the planning, building and site requirements that apply across Redland City.
Do You Need Council Approval for a Granny Flat in Redlands?
A new secondary dwelling in Redlands generally requires building approval and plumbing and drainage approval. Planning approval may also be required depending on the property's zoning, overlays and proposed design, while an Amenity and Aesthetics referral can apply where the secondary dwelling does not meet Council's applicable design and scale criteria.
The current interim Amenity and Aesthetics and infrastructure-charge arrangements make it especially important to confirm the proposed GFA and approval pathway before detailed design begins.

Energy Ratings for Granny Flats — Queensland 2026
Under Queensland Development Code MP 4.1 (Sustainable buildings), an eligible new Class 1a small home with a floor area of 50 m² or less may use a 5-star thermal energy-equivalence pathway. Most larger new homes generally require 7 stars. Eligible raised-floor houses may qualify for a 6-star pathway. These are state energy provisions, not separate council size entitlements; the proposed GFA and eligibility must be checked for the actual design.
Whole of Home energy requirements also apply (generally a minimum score of 60 for new houses). Compliant outdoor living area credits may contribute to the relevant star-equivalence pathway. Before setting a building budget, obtain a project-specific assessment from the energy assessor and confirm applicable compliance requirements with the certifier.

Redland City Granny Flat Rules – What You Need to Know
In Redland City, a granny flat is generally treated as a secondary dwelling associated with the main dwelling on the same property. It can be attached or detached, but it remains subordinate to the primary dwelling and cannot be separately sold from the property.
Redland City Council uses its Amenity and Aesthetics Policy and Guideline to assess the scale and design of secondary dwellings. The following GFA thresholds help determine whether a proposal may need an additional Council amenity and aesthetics assessment:
· Lots under 1,000 m²: up to 85 m² GFA
· Lots of 1,000 m² or more: up to 112 m² GFA
· Rural Zone lots of 6,000 m² or more: up to 160 m² GFA
These are assessment thresholds, NOT automatic maximum buildable sizes or exemptions from all approvals. A design outside an applicable probable solution may require an Amenity and Aesthetics referral. Council also advises that exceeding the relevant GFA threshold can trigger infrastructure charges. Check the zone, overlays and building assessment pathway for the property.
2026 update: Redland City Plan Version 14 remains in effect (commenced 10 November 2025). The proposed 02/25 Major Amendment – Residential includes secondary-dwelling changes, but is not yet operative according to Council’s published status. Redland’s Infrastructure Charges Resolution (No. 3.5) 2026 took effect on 14 October 2026, replacing No. 3.4.
Do I Need Development Approval?
Not necessarily.
Redland City Council states that some secondary dwellings require only building and plumbing approval, while others may also require planning approval. The outcome depends on matters including the property's zoning, overlays and the design of the proposed development.
This is why we recommend assessing the individual property before committing to a design.
Building Approval
Building approval is required for most new building work and is obtained through a private building certifier. The certifier assesses the building work against the Building Act, National Construction Code and relevant Queensland requirements.
Plumbing Approval
New secondary dwellings generally involve plumbing and drainage work. Redland City Council is responsible for assessing plumbing and drainage applications, issuing permits and carrying out relevant inspections.
Setbacks and Building Siting
GENERAL SETBACK GUIDE — Standard lots (450 m² or more): generally 6 m front, 1.5 m side and rear for low-rise sections. Small lots (under 450 m²): QDC MP1.1 road setbacks can start at 3 m to an access street or 4 m to a collector street; side and rear setbacks require individual checking. Corner lots: both street boundaries are road frontages and special visibility rules apply. These are indicative figures only.
The following are GENERAL STARTING POINTS for typical low-rise housing, not universal Redland requirements. Redland City Plan alternative siting rules, particularly LDR precinct controls, may change the result. Confirm boundaries, roof projections, building height and applicable codes for each property.
Residential building setbacks and siting are generally assessed under:
· QDC MP1.1 for lots under 450 m²
· QDC MP1.2 for lots of 450 m² and over
The Queensland Housing Code commenced on 1 September 2026, but Redland Council confirms it has NOT yet adopted the new Code in City Plan. Existing QDC MP1.1 / MP1.2 and local alternative siting provisions continue to apply until adoption or the transition deadline of 1 September 2029.
Queensland Housing Code — Commenced 1 September 2026
Redland Council confirms that the Queensland Housing Code does not apply locally until City Plan is amended to adopt it. The previous QDC MP1.1 and MP1.2 standards and relevant alternative provisions continue in the meantime. Do not treat the new state-code floor areas or setback provisions as current automatic Redland entitlements.
The new Queensland Housing Code includes default secondary-dwelling internal floor-area provisions. These are distinct from Redland’s existing Amenity and Aesthetics GFA thresholds and should not be used to override the current local framework during the transition.
The new framework also updates design and siting standards for building height, setbacks, site cover, visual privacy, vehicle parking and access, and private and landscape open space.
For Redland properties, check the current City Plan zone, precinct and existing QDC provisions before fixing a granny flat footprint. The new state code does not automatically displace the current Redland rules.
For typical single-storey dwellings on lots of 450 m² or more, the following former QDC MP1.2 benchmarks commonly apply unless Redland City Plan specifies an alternative:
· Front / road boundary: 6 m
· Side boundary: 1.5 m
· Rear boundary: 1.5 m
These 1.5 m side/rear figures generally apply to building sections up to 4.5 m high; taller sections can require larger setbacks. Narrow-lot provisions and existing building envelopes may also change the setbacks.
Corner Blocks
For a corner lot of 450 m² or more, both street frontages are treated as road frontages for QDC siting purposes. The standard starting point is generally a 6 m road setback. Where the lot has an average depth of 24 m or less, QDC MP1.2 allows the nominated road frontage to use the reduced setback shown in Table A1, while the other road frontage generally retains the 6 m setback.
A corner lot is also subject to an important sight-line requirement: no building or structure more than 2 m high may be built within a 9 m × 9 m truncation at the corner of the two road frontages under the standard QDC acceptable solution.
For smaller corner lots under 450 m², the former QDC MP1.1 has different road-frontage benchmarks (subject to Redland City Plan alternatives):
· Access place or access street: 3 m to the nominated frontage and 1 m to the corner-side street
· Collector street: 4 m to the nominated frontage and 2 m to the corner-side street
· Side and rear boundaries: generally 1.5 m where the relevant part of the building is 4.5 m high or less
Corner lots under 450 m² are also subject to the 9 m × 9 m corner sight-line requirement.
Setbacks are measured from the outermost projection of the building, which generally means the outside face of the fascia or roof structure rather than simply the external wall.
The Redland City Plan can impose alternative siting provisions in certain residential precincts, including LDR1, LDR2, LDR3, LDR4 and LDR5. These provisions can vary matters such as building height, boundary clearances, privacy, on-site parking, outdoor living space and site cover.
If a proposal cannot meet the applicable QDC acceptable solution or a Redland City Plan alternative siting provision, a design and siting referral to Council may be required before the private building certifier can approve the building work.
Infrastructure Charges — October 2026 Update
Redland City Council’s current Adopted Infrastructure Charges Resolution is No. 3.5 (2026), effective 14 October 2026. Council states that a secondary dwelling exceeding the applicable Amenity and Aesthetics gross-floor-area threshold can attract infrastructure charges. Importantly, infrastructure charges may also arise from assessable building work even if a separate material-change-of-use planning approval is not required. The actual charge and liability must be confirmed with Council for the project.
These setbacks are a guide only. Zoning, overlays, easements, building envelopes, underground infrastructure and other property-specific constraints can affect the final building location.
Parking
Parking requirements should also be checked for the individual property. Redland City Council identifies on-site parking as one of the matters that can be affected by alternative City Plan provisions in particular residential precincts. The required outcome can therefore depend on the property's zoning, precinct and proposed design rather than one universal granny-flat parking rule.
Zoning, Overlays and Site Constraints
A property's zoning and overlays can affect whether planning approval is required and what can be built.
Other constraints may include:
· Flooding or storm-tide impacts
· Bushfire overlays
· Underground sewer, stormwater or water infrastructure
· Easements
· Building envelopes
· Environmental overlays
· Character or locality-specific controls
· Wastewater requirements on non-sewered properties
Redland City Council recommends checking the property's zoning and overlays through its property mapping and development tools before proceeding.
Properties on the Southern Moreton Bay Islands can have additional requirements. For example, Council advises that these islands do not have reticulated wastewater infrastructure, meaning properties require their own wastewater treatment and disposal systems and associated site and soil assessment.
Can a Redland City Granny Flat Be Rented Out?
Yes.
Queensland's secondary dwelling rules were changed in September 2022 so that a secondary dwelling can be rented to any person, regardless of whether they are related to the occupants of the main dwelling.
The dwelling remains a secondary dwelling associated with the main dwelling on the same lot and cannot be separately sold.
This makes granny flats suitable for a range of uses, including independent family accommodation and rental accommodation, subject to the property and proposed development meeting the applicable planning, building and other requirements.
Our Granny Flat Process in Redland City

Frequently Asked Questions
Can I build a granny flat on my Redland City property?
It depends on the property's zoning, overlays, lot size, setbacks, available building area, services and other site-specific constraints. Some secondary dwellings require only building and plumbing approval, while others may also require planning approval.
How large can a Redland City granny flat be?
Under Council's current Amenity and Aesthetics framework, important GFA thresholds are 85 m² on lots under 1,000 m², 112 m² on lots of 1,000 m² or more, and 160 m² on Rural Zone lots of 6,000 m² or more. Proposals exceeding the applicable threshold may trigger Council assessment and infrastructure charges.
Do I need Development Approval?
Not always. Redland City Council advises that some secondary dwellings need only building and plumbing approval, while others may require planning approval depending on zoning, overlays and the proposed design.
Do I still need Building Approval?
Yes. Most new building work requires building approval through a private building certifier.
Do I need plumbing approval?
New secondary dwellings commonly involve plumbing and drainage approval, which is administered by Redland City Council.
Can I rent the granny flat to someone who isn't a family member?
Yes. Queensland's rules allow a secondary dwelling to be occupied or rented by someone who is not related to the occupants of the main dwelling.
Can I customise the design?
Yes. We can develop the concept floorplan around your property, preferred layout, future occupants and budget rather than limiting you to a single standard design.
Can I see completed Hive Small Homes projects?
Yes. Visit our Projects page to see examples of completed Hive Small Homes granny flats and small-home projects.
