Queensland Housing Code: What It Means for Moreton Bay
The introduction of the Queensland Housing Code (QHC) presents an important question for councils preparing new planning schemes: when does local variation improve housing outcomes, and when does it simply add complexity?
The Push For Greater Consistency Is Not New
Ten years ago, a model dwelling house code was proposed in response to the growing complexity of local planning requirements across Queensland. At the time, the Housing Industry Association observed that there were around 500 different variations affecting how a house could be built across the state.
Its 2016 report also found that around half of Queensland’s 20,000 new home approvals and 60,000 renovation approvals each year required some form of local government planning approval, driven in part by differences in local controls for matters such as building height, site cover, private open space and boundary setbacks.
Local circumstances will always warrant some variation, but consistency has clear value. For homeowners, designers and builders, it provides greater certainty, reduces design complexity and supports more efficient housing delivery.
This is particularly relevant for Moreton Bay as it prepares a new planning scheme. Rather than asking which existing provisions should be retained, a more useful question is which local variations deliver sufficient benefit to justify departing from a statewide standard.
The issue is also important from a council resourcing perspective. Through our work with regional Queensland councils, we regularly see dwelling house referrals comprise a significant proportion of overall application workloads. In some local government areas, they account for almost 40% of development applications received.
At a time when housing supply, affordability and assessment efficiency are under pressure, planning resources need to be focused where they can have the greatest impact.
To explore this question, we compared the QHC with Moreton Bay’s current Dwelling House Code using a representative 300 m² lot in the General Residential Zone, Next Generation Neighbourhood precinct.
At a high level, the two frameworks are already closely aligned. Both provide for 60% site cover, a 3 m primary frontage setback and, for the lot tested, a 1 m side setback on the non-built-to-boundary side.
The more useful comparison is where they differ, and whether those differences deliver outcomes that warrant additional local regulation.
Covered Outdoor Living
One practical improvement within the QHC is its recognition of covered outdoor rooms, including alfresco areas, verandahs and decks.
By allowing these structures closer to front and rear boundaries than the dwelling itself, the QHC provides greater flexibility within smaller building envelopes. On increasingly compact residential lots, this can help deliver usable outdoor living areas and better engagement with the street.
It is a good example of a statewide provision providing greater design flexibility without requiring a separate local response.
Built-to-Boundary Development
One of the more significant differences relates to built-to-boundary development.
The QHC generally permits built-to-boundary development along one side boundary for a maximum length of 9 m. Moreton Bay’s current provisions are considerably more flexible, allowing up to 60% of the side boundary length on narrower lots. In the 300 m² scenario tested, this equated to approximately 17 m, almost double the QHC allowance.
There is a clear benefit to this flexibility. On smaller lots, additional built-to-boundary opportunities can maximise the available building envelope and provide greater scope to respond to individual site and design requirements.
The key consideration is whether that flexibility consistently produces outcomes that justify departing from the statewide standard. Where there is a clear and demonstrable benefit, a local variation is warranted. Where that benefit cannot be demonstrated, the QHC provides a simpler and more consistent approach.
Rear Setbacks and Landscaping
The QHC requires a 3 m rear setback on lots smaller than 450 m², compared with the 5 m rear setback that can apply under Moreton Bay’s current provisions.
A smaller setback expands the available building envelope and can assist in delivering efficient single-storey housing on constrained lots.
Larger setbacks can provide additional space for landscaping, tree planting and outdoor living. However, where these are the intended outcomes, regulating them directly is likely to provide greater clarity than relying on setbacks as a proxy.
As detached housing lots become smaller and urban densities increase, a stronger approach is to focus on measurable landscaping and deep planting outcomes rather than imposing additional setback requirements without a clearly defined purpose.
Where Does This Leave Moreton Bay?
The transition to the Queensland Housing Code presents an opportunity to simplify.
The QHC establishes a consistent statewide baseline that can reduce complexity, improve certainty and support more efficient housing delivery. Local variations should not be retained simply because they have always existed. They should be retained where there is a clear planning rationale and they demonstrably achieve a better outcome.
For Moreton Bay, the issue is not simply how its current Dwelling House Code differs from the QHC. It is whether those differences produce benefits significant enough to justify the additional regulation, assessment effort and complexity.
In a planning environment increasingly focused on housing supply, affordability and efficiency, the strongest planning schemes may not be those with the most local provisions. They may be those that intervene only where there is a clear, evidence-based reason to do so.
