My gf is a resident of DC. Over the weekend I am usually at her place and park legally on the streets. I have so far accumulated 4 tickets worth $400 for not having DC tags. I am a resident of Arlington and I just dont see why they keep issuing me a ticket. Its not like my car is at the same spot for 3-4 consecutive days. Its mostly happened on Sunday nights when I've stayed over. Any help would be greatly appreciated. Thank you.

P.S.: Not going over is not being considered.
