Innovative local government policy, read relationally.
The strongest councils treat affordable housing, homelessness, economic opportunity and social cohesion as one connected system, not separate programs. Housing stability lowers health and justice costs and lifts education and economic participation; cohesion makes a place resilient to shocks. This is the DRMC reading: not a menu of policies, but an account of how they reinforce one another.
AiiPD uses the library below to ground council recommendations in proven, costed precedent. Each intervention carries its evidence, its cost and the cities that have run it.
Precedents are predominantly international (Europe, US, Singapore) plus the Australian Human Rights Commission social-cohesion guidance. Figures and models must be translated to the South Australian and Australian local-government context (powers under the Local Government Act and PDI Act, SA Housing Authority, state funding) before they appear in a council-facing recommendation.
Housing First
Permanent housing provided first, with no preconditions (sobriety, employment) and voluntary supportive services.
Evidence: 80%+ housing retention in European cities
Cost: Finland saves about EUR 15,000 per housed person per year through reduced emergency, health and justice costs.
Precedents: Helsinki, Vienna, Houston, Finland
Inclusionary zoning
Require 10-30% of units in new developments to be affordable, often with density bonuses as an incentive; affordability persists across resales.
Evidence: Used in DC, San Francisco and NYC at 10-30% affordable requirements
Cost: Cost-neutral to council where density bonuses offset the affordable requirement.
Precedents: Washington DC, San Francisco, New York
Community Land Trust
A non-profit holds land in trust and leases homes at permanently affordable prices, locking affordability in perpetuity.
Evidence: 1,600+ permanently affordable homes in California
Cost: Seed acquisition fund of roughly 2 to 5 million dollars, then self-sustaining.
Precedents: California, Minneapolis

Accessory Dwelling Unit (ADU) program
Streamlined permits and pre-approved designs that let homeowners add small secondary dwellings, expanding gentle-density supply.
Evidence: US cities adding 200,000+ ADUs annually where permitting is streamlined
Cost: Pre-approved design and permit package of about 10,000 to 25,000 dollars per homeowner.
Precedents: California and US cities

Public / social housing at scale
Council or public development and ownership of a meaningful share of housing stock, integrated and mixed-income to avoid segregation.
Evidence: Vienna: 80% of residents in social housing
Cost: Funded through land value capture, bonds and long-term public investment.
Precedents: Vienna, Singapore
Sources: [1]
Rapid rehousing
Short-term rental assistance (3-12 months) plus case management to move people quickly from homelessness into permanent housing.
Evidence: 70% of participants secure permanent housing before exit
Cost: About 3,000 to 10,000 dollars per household versus 40,000+ per year for shelter.
Precedents: United States (widely deployed)
Sources: [1]
Cross-sector Homeless Outreach Team (HOT)
A coordinated team of police, social workers, healthcare and service providers building relationships and connecting people to housing.
Evidence: Wichita: 100+ people per year connected to housing (named best in the nation, 2019)
Cost: Operating cost of a small multidisciplinary team; offset by reduced crisis and justice costs.
Precedents: Wichita, Houston
Sources: [1]
Tiny home villages
Secure, dignified interim housing with wraparound services while permanent housing is arranged.
Evidence: Minneapolis Avivo Village: 100 units
Cost: Lower capital cost than congregate shelter; interim solution.
Precedents: Los Angeles, Minneapolis
Sources: [1]
Entrepreneur-led economic development
Back local small business and inclusive entrepreneurship (microloans, grants, incubators, streamlined licensing) rather than chasing large corporate relocations.
Evidence: Small businesses are 99% of firms, 46% of the workforce and 55% of new jobs (US BLS 2023)
Cost: Microenterprise fund of about 250,000 to 500,000 dollars (loans/grants of 5,000 to 25,000 dollars); incubator space at 50 to 200 dollars per month.
Precedents: Shops at Sharp End, Columbia MO, NLC City Inclusive Entrepreneurship
Main Street / downtown revitalisation
Repurpose vacant buildings, fund facade improvements, pedestrianise and activate to revive high streets.
Evidence: Main Street programs repurpose abandoned buildings into thriving businesses
Cost: Facade improvement grants of about 5,000 to 15,000 dollars per business.
Precedents: US Main Street programs

Participatory budgeting
Residents directly decide how a portion of the public budget is allocated, lifting civic engagement and institutional trust.
Evidence: Budgets allocated range from 1 million to 30+ million dollars
Cost: Allocate a ring-fenced share of the capital budget; modest facilitation cost.
Precedents: Porto Alegre, Chicago, New York, Espoo, Warsaw
Sources: [1]
Superblocks (car-free neighbourhood cells)
Group blocks into car-limited cells that prioritise pedestrians, play and gathering, improving air quality and social interaction.
Evidence: Barcelona: 21% reduction in air pollution, more social interaction, safer spaces
Cost: Public-realm works; can be staged from low-cost tactical pilots.
Precedents: Barcelona, Paris, Portland, Melbourne
Sources: [1]
Social cohesion measurement (100RC framework)
Baseline and track trust, participation, bridging of divides, safety and institutional trust to manage cohesion as an asset.
Evidence: Socially cohesive neighbourhoods recover about 40% faster from disasters
Cost: Survey plus annual tracking; low cost.
Precedents: 100 Resilient Cities network
Guaranteed income pilot
Unconditional cash of 500 to 1,000 dollars per month to a cohort of low-income residents, measuring housing stability, health and employment.
Evidence: Demonstrated as a cost-effective alternative to fragmented social services
Cost: Pilot of 100 to 500 residents; philanthropic or blended funding.
Precedents: US city pilots
Sources: [1]
Social impact bonds / pay-for-success
Outcome-based contracts where investors fund interventions (homelessness, recidivism, workforce) and are repaid on measured success.
Evidence: Pay-for-success demonstrated for homelessness, recidivism reduction and workforce development
Cost: Shifts delivery risk to investors; council pays on outcomes.
Precedents: US and UK programs
Sources: [1]
Community investment fund / land value capture
Reinvest a share of the budget or uplift in land value into community-designed projects, rotating across neighbourhoods.
Evidence: Funds social housing and community projects without relying on grants
Cost: About 1% of city budget reinvested in community-designed projects.
Precedents: Vienna (land value capture for housing)

Success factors across the evidence.
- Political leadership: mayoral and council commitment signals priority and unlocks funding.
- Community co-design: residents as partners, not recipients.
- Data transparency: public dashboards build trust and enable iteration.
- Cross-sector partnerships: housing plus health plus justice plus education.
- Sustained funding: multi-year budgets blending federal, state, local and philanthropic sources.
- Equity focus: explicitly address racial and economic disparities; disaggregate outcome data.
- Flexibility: allow programs to adapt through rapid iteration cycles.
