The median household income of $119,000 indicates a financially stable tenant base capable of supporting premium ADU rental rates. Job growth of 2.8% annually annually ensures continued population growth and housing demand.

San Francisco's position as the global technology capital creates unparalleled rental demand from highly compensated tech workers, entrepreneurs, and professionals. The concentration of major technology companies, venture capital firms, and startups ensures consistent demand for housing at premium price points, making ADU development particularly lucrative in this market.
