Notably, the Day Street Apts project targets individuals with mental illness. This focus addresses a critical need for housing among a vulnerable population that often faces challenges in securing stable, affordable accommodation.

Over the past decade, the zip code has experienced some demographic shifts. The population has slightly decreased from 29,877 in 2013 to 27,839 in 2022. The median income has remained relatively stable, moving from $70,591 in 2013 to $68,264 in 2022, with some fluctuations in between.

Racial demographics have shown minor changes. The white population has remained the majority, decreasing slightly from 59% in 2013 to 58% in 2022. The Hispanic population has seen a small increase from 27% to 29% during this period. The Asian population has remained relatively stable at around 8-10%, while other racial groups have maintained consistent, smaller percentages.

The completion of the Day Street Apts project in 2014 coincided with a period of relative demographic stability in the area, potentially addressing a recognized need for affordable housing for individuals with mental illness.

Zip code 91042 has a modest LIHTC-funded affordable housing presence, with one project providing 46 units, primarily efficiencies. This project, targeting individuals with mental illness, represents a small but significant contribution to the area's housing diversity. While the LIHTC-funded units cover less than 1% of the estimated housing stock, they address a specific community need. The area's demographics have remained relatively stable over the past decade, with slight shifts in population and racial composition, and fairly consistent median income levels.
