How can I park off street parking with out of state license plates?

I’ll be moving into South Boston and the apartment I’m looking at has only on street parking. It seems all of these parking areas are residential and will require a residential permit. How can I acquire one with my out of state license plate? 🥹

So many new rules coming in! I wanna make sure I do it right (:

Edit: confused off street and on street parking because I’m dumb.
