Are there a lot of charities and free services that homeless people can use?

Depends on the type of homeless. Folks who were just evicted and need someplace safe so they can get back on their feet? Sure. People with severe mental health issues or drug addictions? not so much.

Going to a shelter involves giving up certain freedoms that living outside affords you. If you’re dealing with a heroin addiction, they won’t let you bring your drugs in. Got a pet dog companion? No dogs allowed. Going with a friend or partner? Expect to be split up. Also shelters often fill up and the next shelter with space may be an hour walk away.

It also doesn’t help that the shelters are all separate charities and don’t really coordinate.

So as miserable as it is, many people prefer living in tents and won’t even accept a shelter when they’re offered help as their tent encampment is being cleared by authorities.
