Commercial entry doors are more than just access points. They are the first line of defense for your building. Whether you manage a retail store, office, school, or financial institution, installing entry doors that comply with building code requirements is essential for safety, accessibility, and security.
In an emergency, entry doors also serve as the primary method of exit. If they are not up to code, you risk endangering occupants and violating compliance laws. Below, we will break down some of the most important building code laws that apply to commercial doors and why they matter.
International Building Code
Building codes vary by state, city, and municipality. While there is no single global law, many jurisdictions adopt parts of the International Building Code, which is published by the International Code Council and updated every three years.
Chapter 10 of the International Building Code, titled Means of Egress, covers critical details such as:
-
Minimum door sizes and clearances
-
Ceiling height requirements
-
Approved door hardware
-
Emergency lighting for exits during a power outage
The specific requirements can vary based on the type of building, its occupancy, and the function of the space.

Americans with Disabilities Act
The Americans with Disabilities Act is a federal law passed in 1990. It ensures that commercial facilities across the United States are accessible to people with disabilities. Unlike other codes, ADA compliance is not optional.
Some key ADA requirements for entry doors include:
-
Door openings must provide a minimum of 32 inches clear width when open 90 degrees
-
Door frames must be at least 80 inches tall
-
Handles, locks, and latches must be operable with one hand without tight grasping or twisting
-
Hardware must be mounted no higher than 48 inches from the floor
-
Thresholds must not exceed one-half inch in height for swinging doors and three-quarters of an inch for sliding doors
For businesses, ensuring ADA compliance is critical not only to avoid penalties but also to create an inclusive environment.


National Fire Protection Association
While the National Fire Protection Association standards are not laws on their own, many local governments adopt them to enhance building safety. These codes focus on fire protection and safe egress during emergencies.
Some important NFPA door standards include:
-
Exterior doors must swing outward in buildings with high occupancy
-
Buildings with more than 50 occupants must have panic hardware such as push bars
-
Fire rated doors must be inspected annually
-
A maximum three-quarters of an inch clearance is allowed at the bottom of doors
CDF Distributors offers fire rated doors that meet NFPA standards, giving business owners peace of mind when it comes to compliance and safety.
Other Building Codes
In addition to the International Building Code, the Americans with Disabilities Act, and the National Fire Protection Association, other codes and standards may apply depending on location and building type. These include:
-
The Fair Housing Act in the United States for multi-family housing accessibility
-
LEED Certification Standards for environmentally sustainable construction
-
State and local amendments to national codes
Because codes vary widely, it is best to consult with local officials and trusted suppliers when selecting your entry doors.
