Mandatory Inclusionary Zoning
Affordable housing as part of housing growth.
Australia needs more housing — and more housing that people on lower and moderate incomes can afford. Mandatory Inclusionary Zoning provides a practical way to deliver affordable homes as part of new residential development.
A simple mechanism, built into planning as usual.
Housing growth
New residential development creates the opportunity to grow supply.
Planning requirement
A consistent, known contribution is set through the planning system.
Affordable housing contribution
Homes, land or funding delivered as part of the development.
Homes that remain affordable
Owned and managed by community housing providers, in perpetuity.
Mandatory Inclusionary Zoning requires a proportion of new residential development to contribute to affordable housing. When requirements are established clearly and introduced predictably, they can be incorporated into land and development decisions.
More housing
MIZ works alongside measures to increase overall housing supply.
More affordable housing
It ensures that some of the value and housing created through growth delivers homes affordable to people otherwise excluded from the market.
Greater certainty
A nationally consistent approach can provide clearer expectations for government, industry and communities.
A national approach to Mandatory Inclusionary Zoning
The National MIZ Framework provides a pathway for governments to introduce Mandatory Inclusionary Zoning consistently, predictably and in a way that responds to different housing markets.
01
Contribution settings
Clear minimum requirements and standards.
A uniform minimum requirement — recommended at 10% of residential floor space, in metropolitan areas and fast-growing regional centres — known in advance and consistently applied.
02
How contributions are delivered
Homes, land or other approved contribution mechanisms.
Completed homes, money, or developable land — used separately or in combination, depending on what best suits the scale and stage of a development.
03
Planning and accountability
Local planning, monitoring, reporting and evaluation.
A national picture of affordable homes expected and delivered, built up from local government plans and consistent data standards.
04
Transition and implementation
Advance notice, staged introduction and adjustment over time.
A four-phase timeline — development, notice, transition and operation — gives the market enough forward notice to adjust without disrupting the existing housing pipeline.
05
Roles and responsibilities
Clear responsibilities across Commonwealth, state and territory, local government, community housing and industry.
Every tier of government and the sectors delivering housing have a defined, distinct role — so implementation is coordinated rather than duplicated.
Independent modelling, real-world results
Commissioned modelling from SGS Economics & Planning
Independent economic modelling was commissioned to quantify the impact of a coordinated, nationally consistent MIZ framework — examining its contribution to affordable housing supply, its effect on the development sector and the timeframe for project viability to stabilise.
A growing national coalition
The National MIZ initiative brings together housing organisations, planners, researchers, community housing providers and other organisations interested in strengthening Australia's affordable housing system.
