Decades ago, Baltimore County was divided into 15 election districts. They no longer have any real function in elections, but they remain the basis for apportionment of liquor licenses. In general, one "on-sale" license — that is, a bar or restaurant license — may be issued for every 2,500 people. Randallstown is the only part of the county that is undersubscribed when it comes to licenses, and because of grandfathering, one district, on the county's east side, is vastly oversubscribed. The Dundalk area, by population, should have about 42 licenses, but it actually has 125. Licenses can be bought and sold within a district (provided that the county liquor board approves of the new owner), but they cannot be sold across district lines without a special dispensation from the General Assembly, which controls county liquor laws.
