Affordable Housing & Sustainable Communities Program


The Strategic Growth Council’s Affordable Housing & Sustainable Communities program (AHSC) builds healthier communities and protects the environment by increasing the supply of affordable places to live near jobs, stores, transit, and other daily needs. Personal vehicle use is, by far, the most significant source of greenhouse gas emissions in California. AHSC reduces these emissions by funding projects that make it easier for residents to get out of their cars and walk, bike, or take public transit.

AHSC provides funding for affordable housing developments (new construction or renovation) and transportation infrastructure. This may include sustainable transportation infrastructure, such as new transit vehicles, sidewalks, and bike lanes; transportation-related amenities, such as bus shelters, benches, or shade trees; and other programs that encourage residents to walk, bike, and use public transit.


About AHSC

The Affordable Housing & Sustainable Communities program (AHSC) is administered by the California Strategic Growth Council. The program provides grants and affordable housing loans to projects that provide compact transit-oriented​ development and related infrastructure that can reduce greenhouse gas emissions. 


GHG Strategies

How are GHG reductions calculated?

Greenhouse Gas (GHG) emission reductions are calculated based on the California Air Resources Board (ARB) Quantification Methodology.

Applicants will calculate estimated reductions using the AHSC Benefits Calculator Tool and AHSC Quantification Methodology. These resources can be found on the CCI Quantification Benefits, and Reporting Materials webpage.


Application Tips

Project Application Scoring

How are AHSC Applications Scored?

The AHSC program is competitive and awards the highest scoring projects. Projects are scored and evaluated by project area type: TOD: Transit Oriented Development, ICP: Integrated Connectivity Project, or RIPA: Rural Innovation Project- so, for example, projects in urban areas of the City of Los Angeles do not compete directly with projects in more suburban areas in the Inland Empire.
