Brother thinks someone bugged his apartment, living in car now. Is this a crisis?

Age: 24

Weight: idk

Height: 5'9"

Location: Massachusetts's

Duration: 2 months

Medical History: No medical or psychiatric history but he has been experiences these symptoms for about 2 months.

Medication: none

My brother started to think neighbor put cameras throughout his apartment to stream whatever he was doing in there and selling it on the internet. Currently he is living in his car in a hospital parking lot. He said the Queen of England is still alive and is talking to him as well.

I don't really think he's a danger to himself or others, but he's very paranoid and delusional. Does this qualify for crisis intervention?

Update: I called 988. They said there was nothing to do since he was not a danger to himself, others, or property. I'm also having issues seeing new comments. So, feel free to send me a chat or DM since I can't see new comments.
