As an Architect, I interact with clients, engineers and contractors who have acquired bits of information about Building Codes. Sometimes, those bits are misconceptions and regurgitated information. The building codes can be intimidating and have no beginning or end. To learn the code, the best way is jumping in feet first.
In the next series of blog posts, I will explore common Building Codes. Each City has adopted a code but most in Arizona use the IBC (International Building Code).
The following blog posts are:
The item in bold are addressed in this post. As an Arizona Architect, most City’s jurisdictions work with the IBC (International Building Code). This code analysis is based upon the IBC.
Most 2+ story buildings have elevators. Every once in a while, you may come across an older building that does not have an elevator. When is an elevator required by code?
Per the IBC, at least one accessible route ‘Elevator’ shall connect each accessible level, including mezzanines, in multilevel buildings except:
“Areas not greater than 3,000 square feet and are located above or below accessible levels.”
Per ADA, Elevators are the most common way to provide access in multistory buildings. Exceptions:
“Elevators are not required in facilities under three stories or with fewer than 3,000 square feet”
Scenario 1 – A four-story building has 2,900 square feet per floor. An elevator is not required because each floor is less than 3,000 square feet
Scenario 2 – A four-story building has 3,500 square feet on first floor and 2,500 square feet on each of the other floors. An elevator is required. (All of the stories must be under 3,000 square feet to quality for the exemption.)
Scenario 3 – A two-story building will be used as a real estate office. There will be bathrooms on both ground floor and second floor. Stories are less than 3,000 square feet each. Elevator not required due to exemption. Do the restrooms on second floor need to be ADA compliant? Yes. Restroom on second floor regardless of elevator exemption must be ADA compliant. Why you may ask? There are individuals who may walk up stair using crutches. In addition, ADA contains accesbility features for individuals with disabilities other than those who use wheelchairs.
Definition – “Story” – “Occupiable’ space, designed for human occupancy and equipped with one or more means of egress, light and ventilation. Basements is an occupiable space. Mezzanines are not stories. They are levels within stories.
Do I need an Elevator? Elevators are not required in all buildings greater than 2 stories. Buildings with footprints less than 3,000 square feet may qualify for an exemption. However all other components (restrooms, counter top heights, door clearances etc.) upon the stories will need to comply with ADA requirements
