    I have an existing motel project where they would like to replace the windows, but the existing sills are greater than 44" AFF which was acceptable when the structure was built. Would these be required to be lowered to meet current egress code if they are replaced?

    Thanks, I did a wide search and could not fide a clear answer.

    Does the building have a fire sprinkler system?

    You are talking about just the window in the bedroom?

    Thanks for the reply! Old 50's building in Florida. Two story. Type II-B, not sprinklered. Each unit has one sleeping room and one living area. Living area has a sliding glass door on one side and a 3' man door on the other side to an open covered entryway. Sleeping rooms have 6' wide by 2' tall windows with a 4'-8" sill height. Owner would like to replace windows but not enlarge the openings. All exterior doors are also being replaced with more energy efficient ones, but no rough opening changes. Masonry building with concrete floors and roof.

    Thanks again for any insight.

    Sounds like a Level 1 alteration....So no....

    702.5 Emergency escape and rescue openings. Where windows
    are required to provide emergency escape and rescue
    openings in Group R-2 and R-3 occupancies and one- and
    two-family dwellings and townhouses regulated by the International
    Residential Code, replacement windows shall be
    exempt from the requirements of Sections 1030.2, 1030.3 and
    1030.5 of the International Building Code and Sections
    R310.21 and R310.2.3 of the International Residential Code
    accordingly, provided the replacement window is the manufacturer’s
    largest standard size window that will fit within the
    existing frame or existing rough opening. The replacement
    window shall be permitted to be of the same operating style
    as the existing window or a style that provides for an equal or
    greater window opening area than the existing window.
    Window opening control devices complying with ASTM F
    2090 shall be permitted for use on windows required to provide
    emergency escape and rescue openings.

    Has the Great State of Florida adopted the existing building code?

    Thanks. They are also doing slight kitchen reconfigurations in each unit, so the project is being considered a level 2 alteration.

    Also, I think the motel will be considered R-1 as it is transient housing if that makes a difference.

    EEROs are not required for Group R-1, since Table 1006.3.2(2) only requires them for Group R-2 when on the first story and Group R-1 occupancies are not permitted one exit for stories above grade plane.

    If it is cmu construction, seems like it would be easy to remove one course of block to lower the sill. Or two courses. Not messing with the header.

    Although I do have to question the OP. The title of the post introduces this as an 'R-2', however the proper classification of a motel is 'R-1'. (Unless it is a non-transient mote/hotel, but how often is that the case)

    Yep. I mislabeled. It is indeed R-1. Thanks again everyone for the input...I was stuck in the code and over analyzing it.

    steveray, California adopted that section (about allowing replacement windows of the same kind, even if it makes the rescue openings slightly smaller) when it became apparent that any other option (such as reframing/enlarging openings) would disincentivize people from purchasing more energy efficient replacement windows.
