    Soundproofing in Structures: A Critical yet Overlooked Element of Building Compliance

    Sound transmission regulations, as outlined in Sections 1207.1, 1207.2, and 1207.3 of the International Building Code (IBC) and the Florida Building Code (FBC), are often one of the most overlooked yet crucial aspects of building compliance. These regulations are essential for ensuring a...

    Is the IBC Too Restrictive?

    In the IBC, there are provisions for allowable building heights and areas based on construction type and occupancy.

    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!
