6-Year Housing Production Need Methodology
The housing production need represents the total number of new housing units needed over a 6-year period to accommodate projected growth while addressing existing market imbalances. This comprehensive approach accounts for six distinct components of housing need.
Net Household Growth forms the baseline demand, calculated by projecting net positive household growth as described earlier. The household formation rate captures demographic shifts and changing living arrangements over the forecast period.
Replacement Housing accounts for units lost to demolition, disaster, or conversion to non-residential use. The annual replacement rate is calculated from historical patterns in the American Community Survey's year-built data (B25034), identifying the typical rate at which older housing stock exits the market.
Vacancy Adjustments ensure healthy market functioning by comparing current vacancy rates to minimum stability targets. For owner-occupied units, a 1.5% vacancy rate enables normal market turnover for home sales. For rentals, a 7.4% vacancy rate (derived from historical market equilibrium analysis) allows reasonable choice and mobility. When current rates fall below these thresholds, additional units are needed to restore market fluidity. The adjustment equals the existing housing stock multiplied by the gap between target and actual vacancy rates. Source: Belsky, E. S., Drew, R. B., & McCue, D. (2007).

Overcrowding and Substandard Housing Adjustments address existing deficiencies in housing quality. Overcrowding (more than one person per room) and substandard conditions (lacking complete plumbing or kitchen facilities) are compared to national averages from ACS data. If local rates exceed national benchmarks, additional units are prescribed to provide adequate housing options. These adjustments equal zero when local conditions are less than the national norms.
The total production need sums all components to address market health and housing adequacy.
