About Oakland Housing Authority
Created in 1938, the Oakland Housing Authority, with 3,308 units of public housing and nearly 11,000 units of Section 8, is the third largest housing authority in the State of California. The Authority has a long and successful record of administering leased housing and housing subsidy programs since the inception of Section 23 programs in 1968. The Authority collaborated with other Bay Area public housing authorities (PHAs) to create one of the most "mobile and portable" Section 8 programs, exchanging thousands of participants with a large number of surrounding and distant jurisdictions, and leading the movement to absorb clients rather than bill other PHAs. The Authority has also pioneered in applying for and successfully operating service enhanced programs for special needs populations. Website: www.oakha.org.
