A landing may not be needed for exterior doors under which condition?

In the context of home inspection and building codes, a landing is typically required at the bottom of stairs, including exterior doors, to ensure safety and accessibility. However, there are specific conditions under which a landing may not be necessary.

One of these conditions is when the door in question is a secondary entrance. Secondary entrances often refer to doors that are not the primary access points of a home, like those leading to a basement or a patio. Building codes may adopt different requirements for secondary entrances in recognition of their less central role in the overall accessibility and safety of the home. This may allow for a more flexible approach to the presence of landings for such doors.

The other conditions mentioned involve specifics about riser heights or the configuration of the door, but they do not apply in the same way concerning the classification of the entrance as secondary. Therefore, identifying a door as a secondary entrance provides clarity on why a landing may not be necessary in this particular case.
