Where a principal building is used for a combination of business and residence purposes, the requirements for the R-1 Residence Districts shall hold for the construction and use of all family units. Otherwise none except as noted. Where a lot of record at the time of the effective date of the Zoning Ordinance has less area or width than herein required in the district in which it is located, and the owner or such lot does not own any other parcel or tract adjacent thereto, the lot may nonetheless be used for a one-family dwelling, subject to the following requirements.
(a) The front yard shall be as established in the Zoning Ordinance.
(b) In case the frontage of the lot of record is less than fifty feet, each side yard shall be at least ten percent of the lot frontage; but no side yard shall be less than three feet in any event. If the frontage is more than fifty feet, the side yards shall be as established in the Zoning Ordinance.
