Permission to use a property in a manner that does not meet current zoning requirements.In order to gain a variance,the property owner usually has to show a hardship on the property—not on the owner—if the requested use is not allowed. It is considered a hardship if the property will otherwise remain vacant or if a structurally sound improvement must be demolished to allow some other use.
