If you're referring to Fallstaff and if your zip code is 21215, then that area is most likely firmly in the city. If you're zip code is 21209, then you could be in either the county or the city. I think Shelburne Road and Slade/Park Heights are the cut off roads for the city line. Feel free to post or email the address and one of us can do a tax record search. Or you can go to http://www.dat.state.md.us
and input the property address to pull up the tax record on your own.
