GIẤY PHÉP ĐIỀU CHỈNH ĐẶC BIỆT, hoặc
CHẤP THUẬN/GIẤY PHÉP NGOẠI LỆ ĐẶC BIỆT

Theo em cần thêm cụm 'điều chỉnh đặc biệt' để phân biệt với 'chấp thuận đặc biệt' (special permit hoặc special exception).

A special exception seeks permission to do something that the zoning ordinance permits only under certain special circumstances, e.g., a retail store over 5000 square feet is permitted in the zone so long as certain parking, drainage and design criteria are met. A variance seeks permission to do something that the ordinance does not permit, e.g., to locate the commercial business in an industrial zone (formerly termed a “use” variance), or to construct the new building partially within the side set-back line (formerly an “area” variance); and, as is set forth below in more detail, the standards for any variance without distinction are the subject of much judicial interpretation and flux.
