Housing Development Partners in downtown San Diego is a nonprofit affiliate of the San Diego Housing Commission, created in 1990 to develop and preserve below-market-rate housing from its offices at 1122 Broadway. The organization's real estate portfolio includes rental housing for seniors, families, veterans, and individuals with disabilities, with completed projects earning recognition from the San Diego Housing Federation including the 2017 Ruby Award for The Hotel Churchill rehabilitation—a conversion also honored by Save Our Heritage Organization, the kind of adaptive-reuse work that Civic San Diego has historically guided through the city's planning pipeline. HDP is governed by a five-member board drawn from the Housing Commission, the Housing Authority of the City of San Diego, and an at-large community seat, with all staff positions filled by SDHC employees. New construction and rehabilitation projects utilize Low-Income Housing Tax Credit syndication, HUD funding, and SDHC loan structures to maintain 55-year affordability covenants, a financing model that aligns with the economic-development goals Downtown San Diego Partnership tracks for the central business district. The most complex developments involve full gut-rehabilitation of historic structures into permanent supportive housing with on-site case management, healthcare access, and LEED-certified building systems.
