    California - Hotel - glass shower door size, egress, swing requirements

    For a non ADA unit, will a glass shower compartment door need to meet the CBC Ch.10 egress requirements with a 32" minimum width? The CA plumbing code appears to permit 22" min. width, but in a commercial setting I'd assume the 32" min. width will prevail. Also are there any code sections...

    Carriage Units

    Does anyone have experience with getting Carriage Units approved, especially in CA or Los Angeles? We are trying to clarify if the footprint has to be EXACTLY the same all the way up (IE a giant cube), or if you are allowed to have the footprint get smaller as you go up. Also, does the no...

    Allowable Area of Openings On Diagonal Wall

    We have a wall that is running diagonal to the property line, and so various points of the wall have different allowable areas. How do you go about calculating the total allowable area of openings for the wall? Would we simply add together the allowable area for each segment? It is worth noting...

    Egress Through Fire Wall Used Fir Area Separation

    The code allows you to use a fire wall to consider a portion of the building as a separate building for building area calculations. When this is done, are you allowed to have egress through the fire wall to share an exit or does each separate "building" need to have the required 2 exits?

    2013 CBC/IBC for R-3

    2013 CBC/IBC for R-3 The way we're reading code in Section 1016 is that the overall Exit Distance is limited to 200 feet. According to Section 1014, the Common Path of Travel is limited to 75 feet. This is in a building with two (2) exits. Are we missing anything? Thanks in advance!
