Leasing special purpose properties in Adah (PA), the tenant has the advantage of knowing the building's structure has remained intact for its intended purpose. Changing the floor plan or reconstruction may not be allowed, and the Adah (PA) property may be restricted to very specific types of use. There may be stringent zoning laws, historical preservation, or the Adah (PA) landlord's wishes to keep the property intact and its use a singular purpose.
