I searched but couldn't find that this was previously addressed. Does Appendix E of the 2009 IBC (E107) require the apartment doors off a common corridor to have tactile signs in the first place? The project was reviewed and released over a year ago and now the AHJ is citing Appendix E. Yes, I know that just because something is missed during review doesn't mean the difficiency is allowed to continue but is this a deficiency or a misinterpretation? Does the section mean that "interior and exterior signs identifying permanent rooms and spaces shall be (provided with) tactile (signs)? or that "(if) interior and exterior signs identifying permanent rooms and spaces (are provided they) shall be tactile? Does the fact that the apartment numbers are engraved on the door knockers trigger this requirement? And yes, the appendix is referenced in the adopting ordinance.
