As shown on the attached Official Zoning Map of the City of El Lago, which is incorporated herewith and made a part of this ordinance by reference, Zone A is hereby designated as a one-family district and each and every lot therein shall be used only as a residential lot for residential purposes. The term “residential purposes” as used herein shall be held and construed to exclude use for hospitals, duplex houses, apartment houses, hotels, tourist courts, garage apartments, roominghouses and all other kinds or types of housing accommodations other than a detached, single-family dwelling house and the appurtenances thereto as hereinafter permitted, and shall be held and construed to exclude business, commercial, trade or professional uses.

Only one residence house which shall be a detached single-family residence house, either of one-story, one-and-one-half story or two-story construction, shall be built or permitted on each lot not to exceed two (2) stories or thirty-five (35) feet in height and such house may have an attached or detached garage for not more than three (3) cars, as well as servant type quarters which may be occupied by an integral part of the family occupying the main residence on the building site or by servants employed on the premises.

Any person desiring to cut any curb or otherwise construct any driveway for the purpose of ingress and egress to and from the property to be served shall make application for a permit to the building official. The application shall be in writing and shall be accompanied by a plat or map of the property upon which the driveway is to be located. If approved by the building official, the city secretary shall charge a minimum fee of forty dollars ($40.00) for the issuance of the permit. The fee shall cover the expenses of the issuance of the permit. No permit shall be issued to authorize the construction of a driveway or improved flat surface within the building setback lines described and contained in subsection (11) of this section unless the driveway extends from the curb (i) into the garage located on the property or, if there is no garage there located, to the back building line of the residence house on the property, or (ii) back to the curb if the curb cuts are separated by a distance of at least thirty-five (35) feet. In addition, a permit shall be issued to authorize said construction if a part of the permitted driveway or improved flat surface commences at the curb and extends to a garage, fence or into the back yard of the property to the back building line of the residence house on the property.
