Old Town Alexandria (http://www.visitalexandriava.com/about-alexandria/old-town-a...) is a very dense, built-up historic district. Because space is at such a premium there, lots of residences there are not going to have backyard or garage parking available; it's on-street parking or nothing.
(Source: I live in Alexandria, though not in Old Town -- that neighborhood is crazy expensive. Like, SF expensive.)

We've assigned Officer Smith here to follow you around and make notes about what buildings you enter and exit, and when. He won't follow you into the buildings, of course -- we respect your privacy! He'll just be waiting there for you outside whenever you step out a door.
If this makes you uncomfortable, you are free to cover yourself in a tarp or plastic garbage bag whenever you go outside. Problem solved.
Right?
