2018 IBC 1009.2.1 and "accessible" floors - R-2

[admiralArchArch]

I have two 5 story R-2 (VA) buildings with on level S-2 enclosed parking garage (4 total R-2 stories, NFPA13R). We have an elevator serving all floors. There are no what would be considered "common use areas", only stairs, corridors and the elevator (exception of the mail room on level 1). I had assumed the whole time that per 1009.2.1 that I need to provide an generator in order to have a required elevator serving as a accessible means of egress complying with 1009.4. However, I am starting to doubt that we need standby power because of the portion that says "where a required accessible floor..."

Note that my jurisdiction deletes chapter 11 of the IBC and defers to state accessibility guidelines (ADA 2010).

We have about 36 units per building, per ADA I only need two units with communication features, and one with mobility features. I have located these on the level just above the parking garage, level 2. If I have no accessible units (ie Type A) on the fifth floor, than does that mean that I do not have a required accessible floor?

203.8 Residential Facilities. In residential facilities, common use areas that do not serve residential dwelling units required to provide mobility features complying with 809.2 through 809.4 shall not be required to comply with these requirements or to be on an accessible route.

In facilities with residential dwelling units, at least 5 percent, but no fewer than one unit, of the total number of residential dwelling units shall provide mobility features complying with 809.2 through 809.4 and shall be on an accessible route as required by 206.

Just to confirm, this is public housing, correct?

Correct, multifamily housing, non HUD, LIHTC, or any of that.

Correct, multifamily housing, non HUD, LIHTC, or any of that.

In that case, I'd say you're correct that an accessible route does not need to connect the non-accessible floors (anything above level 2).
