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 simple and more complex Building Codes. Each City has adopted a code but most in Arizona use the IBC (International Building Code).
The issues to be addressed in the following Blog Posts are:
The item in bold is addressed in this post. As an Arizona Architect, most City’s jurisdictions work with the IBC (International Building Code). The code analysis is based upon the IBC.
The ADA (American with Disabilities Act), established in 1990 and in affect in 1988, establishes the minimal clearances required around a door to allow the building occupant to easily approach and open a door with ease. It begin when parents of children with disabilities who began to fight against the exclusion or segregation of their children to minimize the barriers created within public buildings.

Both doors swing in Both doors swing out Door swinging in same direction
Clearance around a door is established by the ADA. The clearances allow for the ease of an occupant to open and pass through a door opening, whether on foot, in a wheelchair or using crutches. A door which swings inward generally increases the required clearances as shown on images above. Other effects like door closures, automatic door openers can affect the operation of a door, however maintaining the shown clearances makes it easier for the occupants and satisfies the current codes established.
