If a building or structure existing prior to the effective date of this section is enlarged to the extent of 50% or more in floor area or number of housing units, it shall then and thereafter comply with the full parking requirements set forth herein.

Off-street parking facilities in existence on the effective date of this section and located on the same lot as the building or use served shall not hereafter be reduced below the requirements for a similar new building or use under the provisions of this section.
