Assessing Land-use Suitability of Existing Inclusionary Zoning Projects in the Australian Capital Territory

Introduction

The document “Assessing Land-use Suitability of Existing Inclusionary Zoning Projects in the Australian Capital Territory” presents a meticulous and critical analysis of a cornerstone of Canberra’s affordable housing policy: Inclusionary Zoning (IZ). At its heart, this report moves beyond simply counting the number of affordable dwellings delivered. Instead, it asks a more profound and nuanced question: Are these homes being built in the right places? It investigates whether the policy, while successful in generating supply, is inadvertently concentrating affordable housing in less suitable locations, potentially entrenching disadvantage rather than alleviating it.

A Comprehensive Look at Where Canberra Puts Its Affordable Housing

The Australian Capital Territory (ACT) government’s Inclusionary Zoning policy, specifically the Territory Plan variation that introduced the Land Rent Scheme and the Affordable Housing Grant, mandates that developers on greenfield sites and certain multi-unit redevelopments set aside a portion of the new dwellings (typically 15-20%) for affordable housing. These homes are then offered to eligible low-to-moderate income households at below-market rates, either for rent or purchase. The primary goal is to promote social mix and ensure that key workers and vulnerable citizens can live within the city they help sustain, rather than being pushed to the urban fringes.

The report’s methodology is systematic and multi-faceted. It first identifies all Inclusionary Zoning developments completed or underway since the policy's inception. It then establishes a robust framework for assessing “suitability.” This framework is not based on a single metric but on a holistic set of criteria that define a liveable and equitable urban location. These criteria are grouped into several key themes:

1. Access to Employment: Proximity to major employment hubs like the Canberra City Centre, Belconnen, Woden, etc., is crucial. Long commutes are a financial and social burden on lower-income households.

2. Access to Public Transport: High-quality, frequent, and reliable public transport is a lifeline for households that may not own a car or for whom car ownership is a significant financial strain. The study looks at walking distance to bus stops and light rail stations.

3. Access to Essential Services and Amenities: This includes the proximity to shops, supermarkets, healthcare facilities, schools, and public open spaces like parks and playgrounds. Easy access to these services reduces living costs and improves quality of life.

4. Social Infrastructure: The presence of community centres, libraries, and other civic spaces fosters social connection and community cohesion.

5. Walkability and Active Transport: The quality of footpaths, cycling paths, and the overall connectivity of the street network. A walkable neighbourhood reduces dependency on cars.

Using Geographic Information System (GIS) technology, the researchers mapped each Inclusionary Zoning development against these criteria, creating a detailed spatial analysis of their relative advantages and disadvantages.

The findings of the report reveal a significant and concerning pattern: a clear geographic disparity in the location of Inclusionary Zoning projects. The analysis shows that affordable housing delivered through this policy is not evenly distributed across the territory’s well-serviced, established areas. Instead, the vast majority of Inclusionary Zoning supply is concentrated in two specific types of locations:

• Greenfield Development Areas on the Urban Fringe: New suburbs like Molonglo Valley (e.g., Wright, Coombs) and Gungahlin (e.g., Throsby, Jacka) account for a large proportion of Inclusionary Zoning dwellings. While these are new, master-planned communities, the report finds they often lag critically in the very amenities that define suitability. At the time of development, and often for years after, they suffer from inadequate public transport frequency, a lack of established employment hubs nearby, insufficient retail options, and underdeveloped social infrastructure. Residents, therefore, face higher transport costs and longer travel times to access jobs and services located in the established town centres.

• High-Density Redevelopment Sites in Certain Established Areas: The other main cluster of Inclusionary Zoning projects is found in higher-density apartment developments, particularly in the inner-north suburbs like Dickson and Downer. While these locations score highly on many suitability criteria—excellent transport links, proximity to the city centre, and good access to amenities—they present a different set of challenges. The high land values and intense development model mean the affordable units are almost exclusively one and two-bedroom apartments. This creates a supply mismatch, as it fails to provide affordable housing for families requiring three or more bedrooms, forcing them towards the less suitable urban fringe.

The report effectively argues that this bifurcated outcome creates a “geography of affordability” with two less-than-ideal pathways for low-income residents: either be housed in a new suburb on the edge where physical infrastructure is lacking, or be housed in a small apartment in a well-located area that is unsuitable for family living. This outcome starkly contrasts with the policy’s goal of creating socially mixed and sustainable communities.

The consequences of this misallocation are profound. Placing affordable housing in areas with poor transport and services exacerbates socio-economic disadvantage. It creates transport poverty, where a high percentage of a household’s income must be spent on fuel, car maintenance, and insurance simply to access employment and essential services. It also limits access to opportunity, reducing the ability of residents to seek better employment, education, and participate in social and cultural activities. Furthermore, concentrating affordable housing in specific areas can lead to the stigmatization of those neighbourhoods and works against the grain of creating truly integrated communities where people of all incomes live side-by-side.

The report is careful to note that the policy itself is not a failure; it has successfully delivered thousands of affordable dwellings that would not otherwise exist. The failure is more subtle—it lies in the implementation and planning controls that allow this geographic concentration to occur. The planning system, in its pursuit of density targets and new land releases, has not adequately baked equity and suitability into the location requirements for Inclusionary Zoning.

The conclusion offers several key recommendations to rectify this spatial imbalance and ensure future Inclusionary Zoning projects genuinely meet the goal of creating suitable, liveable communities. These include:

• Refining Planning Policy: The Territory Plan should be amended to include stronger, explicit requirements for suitability. IZ provisions should be more strategically applied to ensure a proportion of affordable housing is delivered in established, well-serviced areas, not just greenfield sites.

• Promoting a Diversity of Dwelling Types: Incentives or requirements should be introduced to ensure that Inclusionary Zoning delivers not just apartments, but also townhouses and larger family homes in suitable locations to cater for different household types and sizes.

• Strengthening Infrastructure Delivery: There must be a stronger nexus between the release of land for greenfield development and the simultaneous delivery of high-quality transport, retail, and social infrastructure. Affordable housing should not be built in a vacuum of services.

• Continuous Monitoring and Evaluation: The government should adopt the report’s methodology for ongoing monitoring of Inclusionary Zoning outcomes, using GIS-based suitability mapping as a standard tool to evaluate not just the quantity, but the quality and location of affordable housing delivery.

In essence, this document serves as a crucial reality check for urban policy in Canberra and beyond. It argues convincingly that a successful housing policy cannot be just about numbers on a spreadsheet. The address matters. The postcode can determine a person’s access to opportunity, their cost of living, and their overall quality of life.

By highlighting the stark spatial inequality in the outcomes of its Inclusionary Zoning policy, the report provides a powerful evidence base for the ACT Government—and other jurisdictions—to refine their approach. It makes the case for a more thoughtful, equitable, and ultimately sustainable model of urban planning where affordable housing is not an afterthought, but an integrated component of creating thriving, connected, and just cities for all residents.
