Not every entrance has to be accessible, but a defined share does, and IBC 1105 sets the count. In general, at least 60 percent of public entrances must be accessible, and beyond that raw percentage the code requires specific entrances to be accessible based on what they serve — entrances from accessible parking, from pedestrian tunnels or elevated walkways, from transit, and entrances serving tenant spaces all have their own provisions. Each accessible entrance must connect to an accessible route.
The common mistake is meeting the 60-percent count while missing a required specific entrance — for instance, the entrance nearest accessible parking not being one of the accessible ones, or a tenant entrance overlooked.
Reviewers check the accessible-entrance count against the total and confirm the specific entrances tied to parking, transit, and other access points are accessible and connected to an accessible route. It pairs with the accessible-parking and accessible-routes guides, since an accessible entrance is only useful if the route actually reaches it.
