Housing Stock Characteristics

The analysis of housing stock characteristics must include an estimate of the number of substandard units in need of rehabilitation and/or replacement. This information will assist local governments in developing appropriate housing policies and prioritizing housing resources.

Government Code

Government Code Section 65583(a) requires an analysis and documentation of household characteristics, including level of payment compared to ability to pay, housing characteristics, including overcrowding, and housing stock condition, (Section 65583 (a)(2)).

Requisite Analysis

Housing Conditions

Estimate the total number of substandard units — e.g. those in need of rehabilitation (repair) and those in need of replacement (demolition). The number of units to be rehabilitated and/or replaced may be estimated from a recent (e.g., the last five years) windshield survey or sampling, estimates from the local building department, knowledgeable builders/developers in the community, or nonprofit housing developers or organizations. Estimates can also be derived from U.S. Census data, such as percentage of units built before 1980. However, U.S. Census data only serves as an estimate of the maximum rehabilitation need and should be supplemented by local estimates.

Housing Stock Characteristics

The housing element should include a description and analysis of current housing stock characteristics. This information can be used to assist jurisdictions in identifying specific housing needs and tailoring housing programs to fit those needs. Where available, information on tenure (rental or ownership) should be included. This information can be useful because tenure affects the nature of housing problems encountered, as well as the programs or resources that have the potential to address them. The housing element should include information regarding:

Housing costs and affordability

Housing construction prices and trends

Housing units by type

Vacancy rates

*Data from the American Community Survey are available for geographic areas with a population of 65,000 or more for yearly survey; all areas are counted in the five-year estimates.
