Exterior egress balconies shall be separated from the interior of the building by walls and opening protectives as required for corridors.
Exception: Separation is not required where the exterior egress balcony is served by not less than two stairways and a dead-end travel condition does not require travel past an unprotected opening to reach a stairway.
Exterior egress balconies shall have a minimum fire separation distance of 10 feet (3048 mm) measured at right angles from the exterior edge of the egress balcony to the following:
- Adjacent lot lines.
- Other portions of the building.
- Other buildings on the same lot unless the adjacent building exterior walls and openings are protected in accordance with Section 705 of the California Building Code based on fire separation distance.
For the purposes of this section, other portions of the building shall be treated as separate buildings.
