While inspecting a Victorian two-story for a refinance, Edgar noticed the couple who owned the home had installed a separate lockable entry door in the front hall and another at the top of the stairs to separate the main

level from the upper level. They had also converted one of the upstairs bedrooms into a kitchen. The couple had obviously converted the upstairs into a separate apartment. Later, Edgar checked the zoning map in his

office and found that the property is zoned single-family

residential. He called the clerk's office and found that no changes had been made to the zoning. The property is:________.

A) not in legal use according to its zoning. Edgar should appraise the home as a single-family dwelling and make functional adjustments for the lockable entrance doors and the upstairs kitchen.

B) conforming to its certificate of occupancy if there is enough square footage to accommodate two apartments regardless of single-family zoning.

C) a part of the towns buffer strip that mixes commercial and residential in order to maintain a higher level of energy conservation.

D) legally nonconforming because even though it never conformed to zoning laws, it could be easily be converted back to single-family.
