The District of Columbia imposed a permanent moratorium upon the issuance of any permits for the erection or construction of a "Special Sign." Only 32 Special Signs are legally allowed to exist in the District. A Special Sign is not a billboard - at least in legal terms (see below for information on billboards). These legal Special Signs are similar to liquor licenses in that they can be bought and sold and can be moved from location to location within limited boundaries.
