§ 16-203. Additions or expansions to existing structures.

(a) Parking spaces req'd for increased intensity.

If a structure is increased through the addition of a dwelling unit, floor area, seating capacity, or other unit of measurement, off-street parking spaces must be provided for that increased intensity, as required by this title.

(b) Limited exception for preexisting non-residential uses.

However, a non-residential use that was lawfully established before the June 5, 2017, does not need to provide additional off-street parking for that increase until the aggregate increase in units of measurement equals 10% or more of the units of measurement existing on June 5, 2017. Once that level of increase has been reached, however, off-street parking facilities must be provided, as required by this title, for the total increase.
