(a) New Sites. No certificate of zoning compliance or building permit shall be issued for any site development or for the construction or improvement of any building, structure or vehicular use, except where the landscaping for such development, construction or improvement has been approved, as required by the provisions of this chapter. Single-family uses shall be exempt from the requirements of § 1278.04
(d)(2), but all other requirements of this chapter shall apply, unless single-family uses are clearly exempt. However, any person with such a single-family use may request a variance from the provisions of this chapter, for any demonstrated hardship, from the Mayor or his or her designee.
(b) Existing Sites. No building, structure or vehicular use area shall be constructed or expanded, unless the minimum landscaping required by the provisions of this chapter is provided to the property to the extent of the alteration or expansion and not for the entire property of which the alteration or expansion is a part, unless the alteration or expansion is substantial. An alteration or expansion to an existing property is substantial when:
(1) In the case of a building or structure the expansion of which does not involve additional land, the square footage of the alteration or expansion exceeds 25% of the square footage of the existing building, exclusive of the alteration or expansion; and
(2) In the case of an alteration or expansion involving both an existing building or structure and additional land and, if applicable, additional structures or buildings, the area or square footage of the expanded or altered land, structure or building, respectively, exceeds 25% of the area or square footage of the existing land, structure or building, respectively, exclusive of the alteration or expansion. As used in this division, “land” includes land used for space, parking or building purposes.
