What to check in a 2010s house
Quick answer
Houses built in the 2010s (2010–2019) can carry 3 documented era issues, and 3 era boundaries fell inside the decade itself — so early-decade and late-decade builds differ. Pick your exact year below for the precise checklist, phase-in/out flags included.
