(a) Prior to 1964. Any parcel of land zoned for single family dwellings and containing no existing dwelling, which parcel was a lot of record on the plat records or other official records of the Medina County Recorder at the time of the adoption of Ordinance 75-64, passed December 13, 1964, may nevertheless be used as a site for such a dwelling, provided it complies with the following provisions:
(1) Such parcel of land, either alone or when replatted or otherwise combined with all or a part of an adjoining parcel of land, shall have a minimum area of 9,600 square feet and has a minimum lot width of eighty feet on a public street; and
(2) Such parcel of land complies with front and side yard setbacks otherwise required of building lots in that zone and if the rear yard is a minimum of 25 feet.
(3) In no event shall a building permit be issued for any such nonconforming lot unless adequate central water and sanitary sewer facilities are available thereto.
(4) No property owner thereof shall sell or convey a parcel of land which is nonconforming in size and contains a residence structure without also selling or conveying such vacant, adjoining or adjacent parcels of land standing in common ownership. No property owner shall sell or convey any part of a property if, by so doing, the total area, the frontage or the required yards thereof are reduced below those required by the provisions of this Zoning Code.
(b) Since 1964 Any vacant parcel of land zoned for single family dwellings and created as a lot of record on the plat records of the Medina County Recorder between December 13, 1964 and the adoption of this Zoning Code, may be used as a site for such a dwelling, provided such dwelling and all front and side yards comply with the provisions of the applicable zoning district and if the rear yard is a minimum of 25 feet.
(c) Transition Lots. Any vacant parcel of land zoned for single family dwellings and shown as a building lot on an preliminary subdivision plan approved prior to the effective date of this Zoning Code but which is not recorded on that date may used as a site for a dwelling. Such dwelling and all front and side yards shall comply with the provisions of the applicable zoning district, except that the rear yard shall be a minimum of 25 feet.
