Affordable Housing Database (AHD)
The AHPP proactively monitors the City’s expiring affordable housing inventory – Affordable Housing Database (AHD). The City has approximately 69,000 affordable housing units in 1,900 developments, serving very-low, low and moderate-income households.
The City’s current affordable housing inventory (“AHD”) first developed in 1989, has since been regularly updated and improved. The LAHD manages the AHD through its Affordable Housing Preservation Program (AHPP). Efforts are underway to enhance and redesign the database in 2011.
Data Source and Collection
The AHD is comprised of housing units that are assisted and or rent restricted by various federal, state and local sources, as well as units that received non-monetary assistance, such as City land use concessions. This inventory also includes public housing sites managed/owned by the Housing Authority of the City of Los Angeles.
Project data is collected or received from the various agencies and is updated manually. Some of the key data fields include but are not limited to: project name, address, types of funding and affordability restrictions, expiration dates, owner information, unit counts, and fields relevant to the monitoring and preservation of housing.
The LAHD utilizes the database extensively to monitor expiring “at-risk” affordability restrictions, prepare preservation plans, GIS mapping, plan for effective outreach and education, and attend to data requests from elected officials, advocates, preservation developers and the public. In addition, the database provides crucial data for the state-mandated annual update to the City’s Housing Element of the General Plan.
Defining At-risk and Affordability Types
"At-risk" is defined as "primary source" expiring or terminating in the next 5 years. The AHD is based on a development's “primary funding source” or rental subsidy. Specifically, categorizing by “primary source” means that properties/units are attributed to the respective property's rental covenant, rental subsidy or funding source with the most years of affordability. A majority of the properties tracked through this inventory have multiple sources of funding and rental subsidies (e.g. up to five varying sources), however, ONLY their primary, most restrictive source of affordability is accounted in the at-risk count. Projects include new construction, preservation transactions and rehabilitation with affordability restrictions that have been placed in service.
