Core code themes
Roof guards and balcony railings sit at the intersection of life-safety geometry, structural loading, receiving-structure review, parapet conditions, and permit or inspection coordination. That is why they should not be treated as fabrication-only packages.
Public starting points
The most useful public anchors are the active 2022 Construction Codes, DOB's DOB NOW: Build, the Parapets page, and DOB's Special Inspections guidance when anchors or steel details are involved.
