Location. An accessory building or structure may be erected in side and rear yard areas only and shall be set back from side and rear lot lines as prescribed in the individual district regulations, 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.

A maximum of two accessory buildings or structures and two private storage sheds as regulated in § 168-32 shall be permitted. No more than one detached garage shall be permitted per residential lot. Playsets, gym and swing sets and similar structures shall be included in the number of allowable accessory structures. Swimming pools are not to be included in the total number of allowable accessory structures.
