Heating and air conditioning equipment, solar collectors and similar equipment, fixtures, and devices. 6.10.3 ... A. Not more than 30% of the total roof area may be consumed by such features, except in the case of solar panels, which may consume up to 75% of the roof surface. ... 6.10.6 Any structure that overhangs a designated fire lane, as well as any canopy that overhangs a gasoline service station pump island, shall have a minimum vertical clearance of 14 feet.
Full Breakdown
1) but spells out the exceptions in full sentences rather than table cells. 2 lists what may exceed the district's height cap by up to 15 feet: chimneys, church spires, elevator shafts and similar non-occupiable appendages; flagpoles; and rooftop HVAC equipment, solar collectors and similar fixtures. 3: no more than 30% of the total roof area may be consumed by such features, except solar panels, which may cover up to 75% of the roof; each feature must be set back from the roof edge at least one foot for every foot it rises above the roof surface; and the feature cannot interfere with avigation easements described in Article 7's Airport Height/Hazard Overlay Districts.
4 by submitting elevation drawings for review. 5 caps how high a non-residential building's roof access point can be above ground, tying it to the Building or Fire Code, unless the Fire Chief certifies the building has adequate firefighting access or fire protection design. 6 sets a flat 14-foot minimum vertical clearance for any structure overhanging a designated fire lane or any canopy overhanging a gasoline service station pump island, a clearance rule enforced regardless of the underlying district's height limit.
Violations & Fines
Height violations are caught at plan review before a building permit issues; a rooftop feature that exceeds the 30% roof-coverage limit or the one-foot-per-foot edge setback can be required to be redesigned or removed. A canopy or overhang built with less than 14 feet of clearance over a fire lane or fuel pump island is a life-safety violation subject to correction order by the Fire Marshal's office. Relief from the height-bonus conditions requires a variance from the Zoning Board of Adjustments and Appeals, not self-certification.
