Build, assess, and treat side-by-sides just like detached dwellings, right? Not quite. Explore the opportunities, differences, and complications posed by party walls. How do you interpret a blower door reading when much of the air is coming from the neighbor's unit? Builders often use low-rise multifamily attic and party walls as convenient distribution locations for ducting, service shafts, and unvented exhaust devices. Resulting problems include condensation, ice damming, and mold.
