Accessory buildings as part of principal buildings. Accessory buildings may be attached to a principal building, provided that all yard requirements of this article for the principal building, including the attached accessory building, are complied with.

Accessory buildings built prior to principal buildings. Notwithstanding any other provisions of this article, no building permit shall be issued for the construction of an accessory building prior to the issuance of a building permit for the construction of the main building upon the same premises. If construction of the main building does not precede or take place at the same time with the construction of the accessory building, the Construction Official shall have cause to revoke the building permit for the accessory building.

Height and area of accessory buildings. Accessory buildings shall not exceed one story or 15 feet in height and may not occupy more than 25% of a required rear yard or a maximum of 700 square feet, whichever is smaller.

Location. An accessory building or private parking area shall be erected only on the rear half of the lot and, if erected on a corner lot, shall be set back from the side street to comply with the setback line applying to the principal building for that street.

Second dwelling prohibited. In no case shall there be more than one residential building on any subdivision lot of record.

Structures permitted within required open spaces. Balconies, eaves, breezeways, fireplaces, chimneys and patios attached to residences shall not be considered as part of a principal structure and may project into required open spaces, provided that such structures do not exceed 180 square feet, are not enclosed and do not extend any closer than three feet to any lot line.
