A. The powers and duties of the board of adjustment shall be limited to three general types, as follows:
1. It shall have judicial power to interpret the provisions of this title;
2. It shall have administrative power to grant variances;
3. It shall have the administrative power to grant special exceptions or conditional uses.
B. Interpret Ordinance and Map. It is the intent of this provision to provide a way whereby applicants who think that the zoning administrator is in error, or does not interpret the provisions of the zoning title correctly, may obtain relief from such error in an expeditious and inexpensive manner without having to resort to the courts. It is also the intent of this title to empower the board of adjustment to decide, upon appeal in certain zones, whether uses which are not listed therein are, in fact, similar to those which are listed. Accordingly, the board of adjustment shall hear and decide appeals where it is alleged by an appellant that there is error in any order, requirements, decisions, or refusal made in the enforcement of this title. The board of adjustment shall also interpret the zone map and the boundaries thereof in cases of dispute or disagreement and shall determine the similarity or dissimilarity of uses which are not listed as permitted uses in the various zones. Before the board of adjustment shall declare a use to be similar to other uses permitted in the zone, it must find that the requested use will be:
1. Consistent with the objectives and characteristics of the zone in which the use is to be located;
2. Similar to permitted uses as to function, service, and traffic demands and the emission of smoke, dust, vibration, light, etc.
C. Grant Variances. It is the intent of this provision to provide a way whereby an applicant can use his property to the same extent as other properties in the same zone. Accordingly, the board of adjustment may authorize, upon appeal, variances from the terms of this title whereby reason of exceptional narrowness, shallowness or shape of specific piece of property at the time of the enactment of the regulation, or where by reason of exceptional topographic condition, a literal enforcement of the provisions of this title would result in unnecessary hardship upon the owner. Before any variance may be granted, however, the board of adjustment must find that all of the following conditions are present:
1. Having to adhere strictly to the letter of the title will cause difficulties and hardships upon the petitioner which are unnecessary in order to carry out the purposes of this title;
2. Special circumstances attach to the property covered by the application that do not apply to other property in the same zone;
3. That because of said special circumstances, property covered by the application is deprived of privileges possessed by the other properties in the same zone; and that the granting of the variance is essential to the enjoyment of a substantial property right possessed by the other properties in the same zone;
4. That the difficulties and hardships were not created by any act of the appellant subsequent to the effective date of the regulation appealed from.
D. Grant Certain Special Exceptions or Conditional Uses. There are certain uses which are not permitted within particular zones unless they are made to comply with conditions which make them compatible with other uses in the same zone. Accordingly, the board of adjustment shall hear and decide requests for special exceptions or conditional uses, but only when authorized to do so under the terms of this title. In deciding whether or not to grant a special exception or conditional use, the board shall be guided by the following conditions set forth, which shall be deemed to be the minimum requirements that must be complied with.
1. Small Lots. Where a parcel of land at the time of the adoption of the ordinance codified herein is at least one and eight-tenths times as wide and one and eight-tenths times as large in area as required for a lot in the zone, the board of adjustment may permit the division of a parcel into two lots, provided:
a. Such division will not cause undue concentration of population;
b. The characteristics of the zone in which the lot is located will be maintained;
c. In the opinion of the board of adjustment, values in the area will be safeguarded adequately.
2. Transitional Uses. Uses which are permitted on either portion of a lot, which lot is divided by a zone boundary line, may be permitted to extend to the entire lot, but not more than 100 feet beyond the boundary line of such zone in which such use is permitted. Before a permit for such a use may be granted, however, the board of adjustment must find that a more harmonious mixing of uses will be achieved thereby.
3. Adjust or Reduce Off-street Parking Requirements. The board of adjustment may approve substitute parking locations and may reduce the amount of off-street parking required provided:
a. It can be shown that the time of use of the buildings or uses will be at different hours or days so that each use will have the amount of off-street parking available when the building or use is occupied; or
b. Sufficient off-street parking is readily available within the vicinity; or
c. Acquisition of land for such use is unnecessary in order to carry out the purposes of this title.
4. Other Special Exceptions or Conditional Uses. The board of adjustment may grant other special exceptions which it has been specifically authorized to grant under the terms of this title, subject to the conditions expressed therein.
