The provision and maintenance of off-street parking and loading spaces is a continuing obligation of the property owner. No building permit shall be issued until plans are presented that show property that is and will remain available for exclusive use as off-street parking and loading space. The subsequent use of property for which the building permit is issued shall be conditional upon the unqualified continuance and availability of the amount of parking and loading space required by this chapter. Should the owner or occupant of any lot or buildings change the use to which the lot or building is put, thereby increasing off-street parking and loading requirements, it shall be unlawful and a violation of this title to begin or maintain such altered use until such time as the increased off-street parking and loading requirements are met. (Ord. 4128 (part), 1981; Ord. 3380 (part), 1968).
