What is the minimum height requirement for exterior balcony railings?

The minimum height requirement for exterior balcony railings is 42 inches (1,070 mm). This height is specified in building codes to ensure safety by preventing individuals from accidentally falling off the balcony. Railings of this height provide a critical barrier that helps keep people secure, especially in residential or commercial properties where balcony use is common.

Setting the height at 42 inches is a balance between safety and practicality, making it tall enough to deter falls while still allowing for visibility and ease of use when standing next to the railing. In many jurisdictions, building codes have been established to enforce this minimum height as part of broader safety regulations aimed at reducing injuries related to falls from elevated surfaces.
