Current Housing Supply Gap

A gap is the shortage of apartment homes based on current inventory and future construction. For the purposes of the data presented, housing supply gaps are broken down by income levels—based on how much those income groups can afford to pay for housing using HUD’s definition of household affordability. Read our full methodology here.

Currently there is a shortage of 135 apartments in Union County regardless of income level. However, the overall shortage is not necessarily indicative of the inventory available to renters at lower income levels. The shortage is often larger for lower-income households. For households earning below $100,000 annually, the shortage is 12 units.

A negative gap indicates that there is more housing supply affordable to a given income bracket than renters in that income bracket. This is most common for higher income households, whose housing need could be satisfied with an affordable unit as easily as a higher-rent unit. A negative gap does not necessarily indicate a healthy housing environment, as higher-income earners may be occupying units that would otherwise serve as more affordable, workforce housing.

Future Housing Supply Gap

A future housing gap examines changes in population by income group based on state projections for 2030, as well as changes in supply based on average long-term production and loss of units through redevelopment and increases in price.

By 2030, estimates suggest that there will be a 435-unit gap for all households, and a shortage of 245 for households earning below $35,000 annually.
