HACSJ partners with SJCBHS to provide housing for individuals experiencing mental health issues and homelessness.

Sonora Square, located along E. Sonora Street, between S. Center and S. El Dorado Streets, is the result of a collaboration between the Housing Authority County of San Joaquin (HACSJ) and San Joaquin County Behavioral Health Services (SJCBHS).  The site is adjacent to the Crossway Residences, another joint effort of the two organizations which has demonstrated tremendous success.

The project includes the adaptive reuse of an existing one-story commercial building built in 1990, repurposed to provide 11 one-bedroom units for income-eligible residents and 1 one-bedroom unit for the on-site manager. This building will also contain a community room and laundry facilities.  A second three-story building is being newly constructed to include an additional 27 one-bedroom units, all of which will provide affordable, permanent, and supportive housing for those experiencing mental health issues and homelessness. 

The construction of Sonora Square began in April 2022 and is expected to be complete in September 2023.


HACSJ, through the Mental Health Services Act (MHSA), was awarded a $5.3 million grant to acquire and develop the lot at 2 E. Sonora and the commercial building at 401 S. El Dorado.  San Joaquin County awarded Sonora Square $2.1 million in non-competitive No Place Like Home funds and $497,000 in Public Low-Income Housing Association (PLHA) funds.  The City of Stockton contributed $1.1 million in PLHA funds and $718,000 in Community Development Block Grant (CDBG) funds. The project was also awarded $1 million in Low-Income Housing Tax Credits (LIHTC) in September 2021.  HACSJ will provide subsidies through Housing Choice Project-Based Voucher rental assistance. SJCBHS will provide supportive services to residents.
