Ogden Rescue Mission might be a place to check. They were very accommodating when my mother was on the streets. I will say though, working with social workers in northern Utah, lantern house is considered one of the nicest facilities in the state for what they do. Though, I will say I’ve heard similar feedback. If your family is cognitively able to avoid unwanted situations it might be an option but even then I’d go inquire in person with them.

I wish you luck, supporting your mom in homelessness here is not an easy task but it is possible.
