The subject is 4,000 sq. ft. on .3 acres of land. Typical of the neighborhood are semi-detached homes on .1 acres of land. Zoning is legal for either detached or attached. Other legal issues (setbacks, etc.) would allow for a conversion to attached. Construction costs and current prices make such a conversion not financially feasible; however, the neighborhood prices are rising. In this situation would the current use be considered an "interim use?"
