Affordable Housing Supply Challenges in Australia

Housing Supply Challenges have become a pressing issue in the global urban landscape. As urbanization accelerates, the demand for affordable housing is outpacing the supply, leading to significant challenges for cities worldwide. The City of Sydney (CoS) has recognized this issue in their Community Strategic Plan (2014), setting a target to have 7.5% of all city housing be affordable housing, delivered by not-for-profit or other providers. To address these challenges, a comprehensive approach is necessary, involving innovative strategies and learning from successful models implemented in other global cities.

The roots of the affordable housing crisis are deep and varied. Economic inequality, rapid urbanization, and inadequate housing policies are just a few of the driving forces behind the growing scarcity of affordable homes. In many urban areas, the demand for housing far surpasses the supply, leading to skyrocketing property prices and rent rates. As a result, people are often priced out of the housing market, rendering homeownership or even rental accommodation unattainable.

Income disparity plays a significant role in this crisis. As the gap between the wealthy and the poor widens, affordable housing becomes scarce for those on the lower end of the income spectrum. In addition, governments and local authorities often struggle to keep up with the pace of urbanization. Rapidly growing cities require extensive infrastructure and housing developments, yet budget constraints and bureaucratic red tape frequently stall progress.

Furthermore, housing policies and regulations can either mitigate or exacerbate the crisis. In places where land-use regulations are overly restrictive, the development of new housing projects becomes challenging and costly. On the other hand, insufficient regulation can lead to unchecked real estate speculation, driving prices higher and pushing affordable housing further out of reach for many citizens.

To tackle the housing supply challenges, cities around the world have implemented various strategies. The World Economic Forum report, “Making Affordable Housing a Reality for Cities,” provides a comprehensive overview of these strategies. Here are some key approaches:

Land is usually the largest real-estate expense, and securing it at appropriate locations can be the most effective way to reduce costs. In even the largest global cities, many parcels of land remain unoccupied or underused. Some of them may belong to the government and could be released for development or sold to buy land for affordable housing. Private land can be brought forward for development through incentives such as density bonuses—increasing the permitted floor space on a plot of land and, therefore, its value; in return, the developer must provide land for affordable units.

While manufacturing and other industries have raised productivity steadily in the past few decades, in construction it has remained flat or gone down in many countries. Project costs could be reduced by about 30 percent and completion schedules shortened by about 40 percent if developers make use of value engineering (standardizing design) and industrial approaches, such as assembling buildings from prefabricated components manufactured off-site. Efficient procurement methods and other process improvements would help, as well.

Twenty to 30 percent of the cost of housing is operations and maintenance. Energy-efficiency retrofits, such as insulation and new windows, can cut these costs. Maintenance expenses can be reduced by helping owners find qualified suppliers (through registration and licensing) and by consolidated purchasing. For example, buying consortia in the United Kingdom has saved 15 to 30 percent on some maintenance items for social housing.

Improvements in underwriting would help banks safely make more housing loans to lower-income borrowers. Contractual savings programs can help such buyers accumulate down payments and therefore finance purchases with smaller and less risky loans. Such programs can also provide capital for low-interest mortgages to savers. Governments could help cut the financing costs of developers by making affordable housing projects less risky—for instance, by guaranteeing buyers or tenants for finished units.

Several cities have successfully implemented strategies to increase their affordable housing supply. Here are a few examples:

The state government of New South Wales, Australia, is partnering with the private sector and non-governmental and community housing groups to develop or renovate 23,000 social housing units in neighbourhoods that need renewal, along with 500 affordable- and 40,000 private dwellings. Proceeds are re-invested in social housing, community facilities, and public space. Housing assistance is linked to participation in education, training, or local employment.

In China, local governments have limited authority to expropriate rural land for new housing. Chongqing and Chengdu are experimenting with “tradable land quotas,” through which developers are permitted to construct new housing on the periphery of a city in return for opening up additional land for cultivation beyond city boundaries.

Los Angeles recently passed a law allowing motels to be converted into “permanent supportive housing” for the homeless, regardless of current zoning requirements. This is typically quicker and cheaper than new construction, as it involves only adding small kitchens to the motel rooms.

Addressing the affordable housing crisis requires a multifaceted and collaborative approach. Cities must innovate and collaborate to devise effective strategies to increase the supply of affordable housing. By adopting a holistic and inclusive approach, cities can ensure that affordable housing is not just a goal, but a reality for all residents. The benefits of affordable housing extend beyond providing shelter; they encompass improved health, economic stability, and social cohesion. Affordable housing is a cornerstone of vibrant, equitable, and resilient urban communities, and its importance cannot be overstated.
