Frequently Asked Questions
Is the ADA 32-inch requirement the clear opening or the door width?
The 32" is the clear opening — measured when the door is open 90 degrees. This means the actual door panel is typically 34-36 inches wide to account for hinges and hardware.
Do residential homes need ADA-compliant doors?
Standard single-family homes are not required to meet ADA standards. However, Fair Housing Act requires accessible features in multi-family buildings with 4+ units built after 1991.
How does ADA door width compare to standard interior doors?
ADA requires the same 32" clear opening as a standard interior door. The key differences are in approach clearances, threshold height (max ½"), and hardware (lever handles, not knobs).
