Are the mats placed on the floor of my office lobby during wet weather considered carpet that must be firmly attached? (ADAAG 4.3 Accessible route)
No, such mats are "furnishings" not covered by ADAAG. However, section 36.211 of the Department of Justice rule requires that accessible features be maintained so such furnishings cannot degrade the accessible route. So-called "walk-off mats" are designed to provide traction on wet floors and, as long as they are stable and do not pose a tripping hazard, they may actually improve the accessibility of a surface. On the other hand, loose throw rugs, for example, could decrease the accessibility of a surface.
