A recreational vehicle stored on a lot in residential areas of the City provided the owner of the recreational vehicle lives in a house on the same lot or on one of the adjoining lots; not more than one (1) recreational vehicle may be located on or within said lot or adjoining lots, and the recreational vehicle must be stored in a side yard, back yard, or adjoining lot rather than a front yard or driveway, unless the lot is a waterfront lot and storage in such locations is impossible. Recreational vehicles that have current documentation of their approved inspection and registration status, and are currently parked in locations that comply with this subsection as of the effective date of this ordinance, are permitted to remain at their current location. A recreational vehicle stored on a residential lot may be plugged into the electrical system of the home on that lot, may have its doors or windows open, and may have its “slide out” in the out position in preparation for future use or as part of its maintenance and/or cleaning.
