The LIHTC funded housing in Lake St. Louis consists of 22 one-bedroom units, 29 two-bedroom units, and 1 three-bedroom unit. There are no efficiency or four-bedroom units recorded.

One notable project is Lake Ridge, completed in 2016, which targets the handicapped population. This project likely includes features to accommodate residents with physical disabilities, such as wheelchair accessibility and modified living spaces.

Over the last decade, Lake St. Louis has experienced steady population growth, increasing from 23,660 in 2013 to 31,144 in 2022. The median income has also risen significantly, from $83,859 in 2013 to $98,382 in 2022, indicating an overall increase in affluence.

The racial composition of Lake St. Louis has remained relatively stable, with a slight decrease in the white population from 91% in 2013 to 86% in 2022. There has been a small increase in diversity, with slight growth in Asian, Black, and Hispanic populations, as well as those identifying as two or more races.

Despite the population growth and increasing median income, there has been only one LIHTC project (Lake Ridge) completed in the last decade. This could suggest that the city's overall economic growth may have reduced the demand for additional low-income housing during this period.

Lake St. Louis has a small LIHTC funded affordable housing inventory, covering less than 1% of the estimated housing stock. The city has received over $600,000 in LIHTC funding, spread across four projects built between 1988 and 2016. The housing units are primarily one and two-bedroom apartments, with one project specifically targeting the handicapped population. While the city has experienced population growth and increasing median income over the past decade, there has been limited expansion of LIHTC funded housing during this time.
