A.
Accessory buildings as part of principal buildings. An accessory building attached to a principal building shall be considered part of the principal building and the total structure shall adhere to the yard requirements for the principal building regardless of the technique of connecting the principal and accessory buildings.
B.
Accessory buildings not to be constructed prior to principal buildings. No construction permit shall be issued for the construction of an accessory building prior to the issuance of a construction permit for the construction of the main building upon the same premises. If construction of the main building does not precede or coincide with the construction of the accessory building, the Construction Official shall revoke the construction permit for the accessory building until construction of the main building has proceeded substantially toward completion.
E.
Location. An accessory building may be erected in side and rear yard areas only and shall be set back from side and rear lot lines as prescribed in Articles IV through VIII, except that if erected on a corner lot, the accessory building shall be set back from the side street to comply with the setback line applying to the principal building for that side street.
