An outdoor staircase refers to staircase installed on the exterior of a building.
As per the Building Standards Act, outdoor staircases are defined by the following criteria:
For emergency outdoor staircases, the exposed part in the open air must meet the following criteria:
It is worth noting that the installation of outdoor wooden stairs for direct access is generally prohibited.
Applications of Outdoor Staircases
Outdoor staircases are used for general access and emergency purposes. In general use, they are installed in buildings such as office buildings and apartments. In single-family homes, they might be installed when there is a need to access the second floor or higher without entering the interior of the first floor.
Examples include homes with an entrance on the second floor or multi-generational homes where separate entrances are required. Additionally, outdoor staircases can be incorporated into design and aesthetics, such as installing a terrace on the second floor and an accompanying outdoor staircase.
For emergency purposes, specific conditions mandate the installation of outdoor escape stairs. These stairs, providing a direct route without passing through doors, are necessary for buildings:
For buildings taller than 15 floors, special evacuation stairs are mandated instead of regular outdoor escape stairs. Outdoor staircases prove effective as an evacuation route in situations where elevators malfunction or internal staircases are inaccessible due to a fire. However, buildings, especially tall ones, may require additional measures for wind protection, and not all cases strictly meet the definition of complete outdoor stairs.
Principles of Outdoor Staircases
General Outdoor Staircases
The Building Standards Act, Enforcement Ordinance Article 23, specifies the conditions that outdoor staircases must meet:
Outdoor staircases, defined as "landing edges and the like" in the Building Standards Act, fall under the same classification as balconies, verandas, and terraces. Generally, areas enclosed by external walls or columns are included in the building's floor area. When calculating the building area, the measurement typically involves a 1m setback from the tip of the protruding part.
The term "open to the outside air" in the regulation refers to ensuring the "vacant dimensions to the adjacent boundary line" and "vacant dimensions to the building facing the stairs". These conditions vary depending on the specific local government, necessitating caution.
Outdoor staircases with the following two conditions can be excluded from floor area calculations:
Outdoor Escape Stairs
In the "Explanation of Fire Prevention and Evacuation Regulations for Buildings," outdoor escape stairs must meet the following additional conditions:

However, for fire-resistant buildings meeting certain conditions, the obligation to install outdoor escape stairs might be exempted for buildings with five floors or more.
