In this zoning appeal out of Alleghany County, the Commonwealth Court was asked whether preservation requirements imposed by a government agency on property that it owned, may constitute an unnecessary hardship to justify a variance. In concluding such a hardship is self-imposed and does not warrant a variance, the court focused on the fact that no legal authority required preservation, and that the more appropriate solution was for the City to rezone the site rather than have the applicant seek a variance.
