§ 17.52.020. Power to hear and grant appeals and variances.
The board of appeal shall have the following powers:
A.
Upon appeal or petition, to grant variances from the terms of this title where the board finds that, owing to circumstances relating to soil conditions, shape or topography specifically affecting such land or structures but not the zoning district in general, a literal enforcement of the provisions of this title would involve substantial hardship, financial or otherwise, to the petitioner or appellant, and that desirable relief may be granted without nullifying or substantially derogating from the intent or purpose of such an ordinance, and without substantial detriment to the public good;
B.
To hear and decide appeals of decisions or orders made by the inspector of buildings or other administrative official, in accordance with Chapter 40A, Section 7, General Laws. Any appeal of a decision or order made by the building inspector or other administrative official shall be taken within thirty days from the date of such decision or order by filing written notice of appeal, specifying the grounds thereof, with the city clerk, who shall forthwith transmit copies to such person whose decision or order is being appealed and to the board of appeals. Such person shall forthwith transmit to the board of appeals all documents and papers constituting the record of the case in which the appeal is taken.
