No part of a yard or other open space about any building required for the purpose of complying with the provisions of this chapter shall be included as a part of a yard or open space similarly required for another building.

No structure shall be used or occupied as a dwelling if such structure is in need of such major structural repairs as to render it unsafe or unsanitary, or if the premises do not have connection with the municipal sewer system or alternative sanitary sewage facilities approved by the local public health authorities having jurisdiction.

Nothing in the district regulations shall be held to prohibit the erection of a one-family dwelling upon a lot whose size is inadequate to meet the lot area regulations set for the district, provided that such lot on the effective date of this chapter was held under separate ownership from the adjoining lots or is a lot in a recorded plan which complies with all district regulations, except lot area requirements, or is a lot in a subdivision plan approved under the Borough of Westmont subdivision regulations.[1]

Mobile homes, home trailers or auto trailers shall be permitted for permanent occupancy in the R-3 District and in mobile home parks only.
