Their foot steps sound like they just have 2 pegs for feet… they hit so hard.

And they frequently, almost daily, spend the entire evening stomping around the entire footprint of their apartment.

Are there people who really just get the top floor, and think “I’m so smart, and everyone else can get fucked” then proceed to make all the fucking noise in the world?

    First, IBC has had this as code for at least 15 years.

    The International Building Code (IBC) establishes minimum requirements for airborne and impact performance of multifamily buildings. The minimum code requirement is STC 50 and IIC 50. Since many factors can affect the transmission of sound in the field, including non-standardized source and receiver rooms as well as construction tolerances, a field measurement (ASTC or AIIC) of three to five points below the lab measurement is acceptable to meet code requirements.

    As the understanding increased of how STC and IIC ratings correlate with occupant comfort, the International Code Council (ICC) issued ICC G2-2010, “Guideline for Acoustics,” which established two additional levels of acoustical performance:

    acceptable, defined as STC 55 and IIC 55; and preferred amount of isolation as STC 60 and IIC 60

    Second, all the money is most definitely not in the land. As a general ballpark, developers want the land to be under 1/4 of the total cost of the project.

      Nice. How effective is that minimum standard? Most currently existing buildings are of course older than 15 years so most people won’t have experienced it. Sadly these days anywhere remotely urban has way more than 1/4 the cost as land, espically for already existing buildings
