(a) A principally permitted use is a use for which the district is reserved. Creation of or transition to such a use in a district for which it is principally permitted requires that a zoning certificate be obtained. Chapter 1127 lists principally permitted uses for each individual district. For information regarding zoning certificates, see Section 1107.02.
(b) A conditionally permitted use is a conforming use within a district, other than a principally permitted use. The Board of Zoning Appeals must determine the compatibility of the proposal with the adjacent uses. The conditionally permitted uses are listed in Chapter 1127. For information regarding conditional use permits, see Section 1109.03.
