(KSL News) -- A two-alarm fire caused $100,000 damage to a home this evening.
The home that burned is part of a five-home complex used by Valley Mental Health Services.
One firefighter was injured slightly, but none of the 23 people who live at the complex was injured.
The hope right now is that all of them can get by in the four surviving homes.
Investigators say they won't know what caused the fire until tomorrow.
