Yep, cities may have regulations for that, and they usually do these days.

And I don't necessarily agree with your preference. My family used to own a large, historical house that had a huge front wall because the terrain was very elevated from street level. And I can tell you from experience, most "graffiti" is worthless crap scrabbled by drunk teenagers without ANY artistic talent or ANY worthwhile message to the world. If you give graffiti a pass because there's the one-in-a-million Banksy, you should also tolerate ads everywhere because a few of them happen to be awesome.

No, I still prefer graffiti.
