New York City conditions
Building basement for New York City conditions
In New York City, the Northeast winters drive frost depth and water movement, so waterproofing and a working drain plane come before any framing. Radon is common across this region, so radon-resistant detailing and a sealed sub-slab system are scoped in from the start, in place before the test is ever run. Code-compliant egress and ceiling height are checked first, since they decide whether the space can legally count as living area in New York City.
