If you mean homeless shelters, yes, but they're horrible and most homeless (or underhoused) people would rather live in a tent than go there. The justifications given are usually assault, thievery, and not being able to bring any personal possessions. I can understand why someone wouldn't want to stay in a shelter if it meant leaving all of their belongings unattended (if you're homeless you probably don't have a storage space or a friend's garage).
