Section 674:33 - Powers of Zoning Board of AdjustmentI.(a) The zoning board of adjustment shall have the power to:(1) Hear and decide appeals if it is alleged there is error in any order, requirement, decision, or determination made by an administrative official in the enforcement of any zoning ordinance adopted pursuant to RSA 674:16; and(2) Authorize, upon appeal in specific cases, a variance from the terms of the zoning ordinance if: (A) The variance will not be contrary to the public interest;(B) The spirit of the ordinance is observed;(C) Substantial justice is done;(D) The values of surrounding properties are not diminished; and(E) Literal enforcement of the provisions of the ordinance would result in an unnecessary hardship.(b)(1) For purposes of subparagraph I(a)(2)(E), "unnecessary hardship" means that, owing to special conditions of the property that distinguish it from other properties in the area: (A) No fair and substantial relationship exists between the general public purposes of the ordinance provision and the specific application of that provision to the property; and(B) The proposed use is a reasonable one.(2) If the criteria in subparagraph (1) are not established, an unnecessary hardship will be deemed to exist if, and only if, owing to special conditions of the property that distinguish it from other properties in the area, the property cannot be reasonably used in strict conformance with the ordinance, and a variance is therefore necessary to enable a reasonable use of it.(3) The definition of "unnecessary hardship" set forth in subparagraphs (1) and (2) shall apply whether the provision of the ordinance from which a variance is sought is a restriction on use, a dimensional or other limitation on a permitted use, or any other requirement of the ordinance.(c) The board shall use one voting method consistently for all applications until it formally votes to change the method. Any change in the board's voting method shall not take effect until 60 days after the board has voted to adopt such change and shall apply only prospectively, and not to any application that has been filed and remains pending at the time of the change.I-a.(a) Variances authorized under paragraph I shall be valid if exercised within 2 years from the date of final approval, or as further extended by local ordinance or by the zoning board of adjustment for good cause, provided that no such variance shall expire within 6 months after the resolution of a planning application filed in reliance upon the variance.(b) The zoning ordinance may be amended to provide for the termination of all variances that were authorized under paragraph I before August 19, 2013 and that have not been exercised. After adoption of such an amendment to the zoning ordinance, the planning board shall post notice of the termination in the city or town hall. The notice shall be posted for one year and shall prominently state the expiration date of the notice. The notice shall state that variances authorized before August 19, 2013 are scheduled to terminate, but shall be valid if exercised within 2 years of the expiration date of the notice or as further extended by the zoning board of adjustment for good cause.II. In exercising its powers under paragraph I, the zoning board of adjustment may reverse or affirm, wholly or in part, or may modify the order, requirement, decision, or determination appealed from and may make such order or decision as ought to be made and, to that end, shall have all the powers of the administrative official from whom the appeal is taken.III. The concurring vote of any 3 members of the board shall be necessary to take any action on any matter on which it is required to pass.IV.(a) A local zoning ordinance may provide that the zoning board of adjustment, in appropriate cases and subject to appropriate conditions and safeguards, make special exceptions to the terms of the ordinance. All special exceptions shall be made in harmony with the general purpose and intent of the zoning ordinance and shall be in accordance with the general or specific rules contained in the ordinance.(b) Special exceptions authorized under this paragraph shall be valid if exercised within 2 years from the date of final approval, or as further extended by local ordinance or by the zoning board of adjustment for good cause, provided that no such special exception shall expire within 6 months after the resolution of a planning application filed in reliance upon the special exception.(c) The zoning ordinance may be amended to provide for the termination of all special exceptions that were authorized under this paragraph before August 19, 2013 and that have not been exercised. After adoption of such an amendment to the zoning ordinance, the planning board shall post notice of the termination in the city or town hall. The notice shall be posted for one year and shall prominently state the expiration date of the notice. The notice shall state that special exceptions authorized before August 19, 2013 are scheduled to terminate, but shall be valid if exercised within 2 years of the expiration date of the notice or as further extended by the zoning board of adjustment for good cause.V. Notwithstanding subparagraph I(a)(2), any zoning board of adjustment may grant a variance from the terms of a zoning ordinance without finding a hardship arising from the condition of a premises subject to the ordinance, when reasonable accommodations are necessary to allow a person or persons with a recognized physical disability to reside in or regularly use the premises, provided that:(a) Any variance granted under this paragraph shall be in harmony with the general purpose and intent of the zoning ordinance.(b) In granting any variance pursuant to this paragraph, the zoning board of adjustment may provide, in a finding included in the variance, that the variance shall survive only so long as the particular person has a continuing need to use the premises.VI. The zoning board of adjustment shall not require submission of an application for or receipt of a permit or permits from other state or federal governmental bodies prior to accepting a submission for its review or rendering its decision.VII. Neither a special exception nor a variance shall be required for a collocation or a modification of a personal wireless service facility, as defined in RSA 12-K:2.VIII. Upon receipt of any application for action pursuant to this section, the zoning board of adjustment shall begin formal consideration and shall approve or disapprove such application within 90 days of the date of receipt, provided that the applicant may waive this requirement and consent to such extension as may be mutually agreeable. If a zoning board of adjustment determines that it lacks sufficient information to make a final decision on an application and the applicant does not consent to an extension, the board may, in its discretion, deny the application without prejudice, in which case the applicant may submit a new application for the same or substantially similar request for relief.Amended by 2022 , 272: 74, eff. 8/23/2022.Amended by 2018 , 214: 1, eff. 8/7/2018.Amended by 2018 , 168: 2, eff. 8/7/2018.Amended by 2018 , 168: 1, eff. 8/7/2018.Amended by 2018 , 75: 2, eff. 7/24/2018.Amended by 2018 , 75: 1, eff. 7/24/2018.Amended by 2013 , 270: 3, eff. 9/22/2013.Amended by 2013 , 267: 9, eff. 8/25/2013.Amended by 2013 , 93: 2, eff. 8/19/2013.Amended by 2013 , 93: 1, eff. 8/19/2013. 1983, 447:1. 1985, 103:20. 1987, 256:1. 1998, 218:1, eff.
