ADU Finance Program
The San Diego Housing Commission’s (SDHC) Accessory Dwelling Unit (ADU) Finance Program helps homeowners with moderate income in the City of San Diego build ADUs on their property. The program provides financial assistance in the form of construction loans (up to $250,000) and technical assistance that helps homeowners understand and complete the process of building an ADU.
Participating homeowners may generate wealth for themselves through the increase in their property’s value and the rental income from their ADU. In addition, the program helps create affordable rental housing in the City of San Diego because the rents for the ADUs built with help from the program are required to remain affordable for seven years.

- 1% fixed interest rate

ADU Development Pilot Program
To help San Diego homeowners understand the process related to ADU construction, the San Diego Housing Commission (SDHC) built ADUs in the available yard space at five single-family homes SDHC owns and rents as affordable housing in the City of San Diego.
Through this process, SDHC documented “lessons learned” with regard to site feasibility, design, construction, cost, timeline, oversight needed, and other development-related aspects that may arise with the development of ADUs.
