The first LIHTC project, Denise Apts, was completed in 1988, while the most recent addition, Chimes Terrace, was finished in 2014. The 2000s were the most active period for affordable housing development, with four projects completed: Ridgeview Manor I (2001), Ridgeview Manor II (2003), Luke's Crossing (2008), and Ridgeview Manor III (2011). The LIHTC-funded projects in this zip code primarily feature two-bedroom units (72) and three-bedroom units (29), indicating a focus on accommodating families or individuals requiring more space.

Over the past decade, zip code 43031 has experienced steady population growth, increasing from 12,035 in 2015 to 13,615 in 2022. Simultaneously, the median income has risen significantly, from $77,795 in 2015 to $96,088 in 2022. This upward trend in income may explain the absence of new LIHTC projects since 2014, as the overall economic situation of residents has improved.
