Under the AHBP, affordable housing is for very low, low, moderate, and middle-income households. The chart above illustrates how these terms are defined and what professions tend to fall into each category.
AMI: Area Median Income
- Very-low income households: Earn up to 55 percent of the Area Median Income in San Francisco
- Low-income households: Earn up to 80 percent of the Area Median Income in San Francisco
- Moderate-income households: Earn up to 120 percent of the Area Median Income in San Francisco
- Middle-income households: Earn up to 140 percent of the Area Median Income in San Francisco
Half of the households in San Francisco earn below the AMI while the other half of households earn above the City’s AMI. AMI is set each year by HUD and is based on household size and the income households earn in the area. The City uses these annually published income limits to inform its various housing programs.
The total of all salaries earned by all people living in the same home equals the household’s total annual income. Based on the 2010 American Community Survey (also known as the U.S. Census), the typical San Francisco household has approximately 2.4 people.
