One of the biggest issues in housing is providing homes for the workforce. Especially vital workers such as police, fire fighters, nurses, and teachers. Unfortunately, many of these workers wages do not allow them to afford even a basic home near where they work.
This makes it especially hard to recruit these workers as they can't afford to live near their jobs.
Workforce housing has many challenges over the years as it first is not clearly defined. Secondly it requires 3 levels of government to work together, and last private industry has to do it's share as well.
Whenever you try to get that many entities working together it's going to be a challenge, but a worthy one.
