I would suggest Jim Butcher's The Dresden Files, which stars the only wizard in the phonebook in Chicago.
Storm Front is the first in the series, though some people do suggest skipping straight to book three,
Grave Peril.
I recently read
Fated by Benedict Jacka, which is very similar in tone to Dresden. Alex Verus, Jacka's main character, is a "probability mage": he can see the future. Verus is not a particularly showy mage, but he's clever and I enjoyed the book very much.
Hounded, first in the Iron Druid Chronicles, is by Kevin Hearne. Atticus O'Sullivan is a Druid who has a couple thousand years of experience under his belt, and has gotten on the bad side of the Celtic god of love. Personally I found it a bit lacking, but I did eventually pick up the second book from the library, and enjoyed it enough that I will probably eventually read the rest of the series.
I read
Nightlife, by Rob Thurman, about three years ago, so most of it is fuzzy. The main character is Cal Leandros, who, along with his half-brother, has been on the run from his father, one of the monsters that plague most urban fantasy settings.
Finally, and
highly recommended, is Brandon Sanderson's
The Alloy of Law. It's not urban fantasy, but more like steampunk-ish fantasy, and is set in the universe that Sanderson created in his Mistborn trilogy. (
The Alloy of Law, however, is set three hundred years after the events of the trilogy, and can be read as a standalone, which is why I'm suggesting it.) Waxillium "Wax" Ladrian returns to the city from "the Roughs," and along with his friend Wayne investigates a series of robbery/kidnappings.
And I think that's it for now. Hope one of these strikes your fancy!
