512.2 Flat-Roofed Buildings and Structures 100 Feet or Less in Height

Solar panel installations shall not obstruct any rooftop area access to which is required pursuant to FC504.4, except that solar panel installations may obstruct the clear path required by FC504.4.4 as follows:

1. if the installation is provided with a hinged mechanism or other device for which a certificate of approval has been issued that enables the installation to be safely swung, slid, lifted, collapsed or otherwise moved out of the clear path, and that is designed to allow for operation by one person, without the use of a tool; or
2. on any building with a rooftop width or depth of 25 feet (7620 mm) or less, where the design of a solar panel installation necessitates coverage of all or substantially all of the rooftop across the full width or length thereof, the commissioner may authorize permanent obstructions that encroach upon and thereby reduce the clear path width within such area when necessary to accommodate the presence of hatches; scuttles and skylights; bulkheads; attic ventilators; chimneys and plumbing vents; and heating, ventilation and air conditioning equipment or other rooftop building service equipment.
