2. When original plans are available, these must be used...

a.      to determine the color scheme of a building.

b.     to justify the removal of later additions.

c.     to justify the addition of a porch which was removed in the past.

d.     to return the building to its original state.

WRONG

Later additions may be kept, or removed if approved by the Historic Preservation Board, even if old plans are not available. If the owners want to return a building to its original state, as shown by old photographs, or the original architectural plans, this would definitely be allowed.
