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.

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 currently uses its Amenity and Aesthetics Policy and Guideline to manage the size and scale of secondary dwellings. The current gross floor area thresholds are:

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 figures are important thresholds rather than a simple blanket maximum size. A proposed secondary dwelling that does not comply with the relevant probable solutions may need to be referred to Redland City Council for an Amenity and Aesthetics assessment, and an infrastructure charge may also apply where the applicable GFA threshold is exceeded.

2026 status: Redland City Council withdrew the earlier proposed secondary-dwelling planning amendment in October 2025. Council's Amenity and Aesthetics Policy and Guideline and the current Adopted Infrastructure Charges Resolution continue to provide interim controls while the broader residential amendment progresses.

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

Granny flat setbacks in Redland City depend on the lot size, building height, whether the property is a corner lot and whether the Redland City Plan contains an alternative siting provision for the 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 transition commenced on 1 September 2026. Existing local-government planning-scheme siting provisions can continue during the transition until Council specifies how the Code applies, or until 1 September 2029, whichever occurs first. Redland City Plan and Council's applicable Amenity and Aesthetics requirements therefore remain important for the individual property.

For a typical single-storey granny flat on a lot of 450 m² or more, the standard QDC starting setbacks are generally:

Front / road boundary: 6 m
Side boundary: 1.5 m
Rear boundary: 1.5 m

The 1.5 m side and rear clearance applies where the relevant part of the building is 4.5 m high or less. Where the relevant part is higher than 4.5 m, larger boundary clearances apply.

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 lots under 450 m², QDC MP1.1 generally provides the following road setbacks:

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.

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

1. Preliminary Site Assessment
We review the property, planning controls, overlays and available information to identify any obvious constraints.

2. Indicative Quote
Based on the preliminary assessment and your requirements, we prepare an indicative quote to give you a clear guide to the likely project cost before moving forward.

3. Site Visit
If the indicative quote is within your budget, we arrange a site visit to look more closely at access, services, site levels and the proposed building location.

4. Concept Design
We prepare a concept floorplan designed around your property, requirements and budget.

5. Final Pricing & Contract
Once the concept design is agreed, detailed pricing is prepared and the final scope is confirmed before proceeding to contract.

6. Working Drawings, Engineering & Approvals
The project moves through working drawings, engineering and the required building and plumbing approval process.

7. Construction
Once approvals are in place, construction can commence with the appointed builder.

Custom Granny Flat Designs for Redland City Properties

A well-designed granny flat should feel like a genuine home rather than simply a smaller version of one.

Depending on the available space, applicable controls and chosen layout, designs can include:

One or two bedrooms
Open-plan kitchen, dining and living areas
Full bathroom and laundry facilities
Built-in storage
Covered decks and outdoor living areas
Energy-efficient insulation and glazing
Air conditioning and ceiling fans
Modern kitchens and bathrooms

We can adapt the concept design to suit different block shapes, site conditions and the needs of the future occupants.

Granny Flats for Different Stages of Life

A Redland City granny flat can provide flexible accommodation for:

Parents or older family members
Adult children wanting greater independence
Extended family
Guest accommodation
Home office or hobby space
Rental accommodation

The best design will depend on who will use the dwelling, how much privacy is required and how the new building relates to the existing home and property.

September 2026 Queensland Housing Code and Energy Update

Important: the Queensland Housing Code (QHC), comprising QDC Parts 1.1 and 1.2, commenced on 1 September 2026. It replaces the 2010 QDC Parts 1.1 and 1.2 at State level, but existing local-government planning-scheme siting provisions can continue during the transition until the council amends its planning scheme to state how the QHC applies, or 1 September 2029, whichever occurs first.

For that reason, the council-specific rules and figures already set out on this page remain important. A homeowner should not assume that every new QHC setback, site-cover or secondary-dwelling size figure automatically applies to the property today. The current council planning scheme, any alternative provisions, overlays, existing approvals and the building certifier's assessment must still be checked for the individual site.

Secondary-dwelling size under the new QHC

The QHC introduces a State acceptable-solution benchmark for a secondary dwelling of up to 50 m² internal floor area on lots under 1,000 m² and up to 60 m² internal floor area on lots of 1,000 m² or more. This is an acceptable solution rather than a universal planning-scheme GFA cap, it uses the QHC definition of internal floor area rather than the council's gross floor area measurement, and adopting councils can provide alternative provisions. The existing council size rules described elsewhere on this page should therefore continue to be checked until the council's QHC transition position is confirmed.

Energy efficiency - new small-home pathway

From 14 August 2026, QDC 4.1 provides a 5-star thermal-performance pathway for eligible small homes of 50 m² or less. Most houses and townhouses otherwise remain subject to the 7-star thermal-performance requirement, while eligible raised-floor houses can use the 6-star pathway. Whole of Home energy-budget requirements also continue to apply where relevant. Eligibility should be confirmed by the energy assessor and building certifier for the proposed design.

Other matters covered by the QHC

The QHC establishes updated State design-and-siting standards dealing with matters including building height, front/side/rear setbacks, site cover, privacy, car parking and access, private open space and landscaping. During the transition, the practical requirement for a particular property may still come from the council planning scheme or an existing local alternative provision. This page therefore retains the detailed current council information rather than replacing it with a single State-wide rule.

Redland transition note

Redland's current City Plan and Amenity and Aesthetics framework described on this page should continue to be checked. The 85 m² / 112 m² / 160 m² figures discussed on this page are amenity-and-aesthetics probable-solution thresholds rather than a simple State-wide maximum, and the QHC's 50/60 m² internal-floor-area acceptable solution should not be substituted without confirming the applicable transition position.

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.
