2003 ANSI A117.1 Section 504.5 requires "the leading 2" of the tread shall have visual contrast of dark-on-light or light-on-dark from the remainder of the tread."
The commentary states, "the intent of the striping is to allow persons with visual impairments to identify the forward edge or each tread and landing. The change from the level walking surface to steps may be a tripping hazard."
I have completed a plans review on a typical three story walk-up apartment building and included a comment stating the contrasting striping on the stair treads is required.
The design professional has responded stating that since ANSI 504.5 is not specifically referenced in Chapter 11 of the building code, it does not apply.
He also refers to the definition of "Accessible" in the 2006 IBC and the commentary for this definition which says in part "It is not the intent of the code to accommodate fully every type and range of disability;it would not be feasible to do so."
Even though an elevator is not provided to the upper floors of the apartment building, I would think their would still be visually impaired persons capable and willing to use the stairs, and as such, the visusal contrast would be required on the stairs.
Any thoughts or code references applicable to this situation would be appreciated.
