Do you know which government in the United States is the biggest laggard on energy codes for homes? The federal government. But that’s about to change.
Manufactured homes and the “HUD Code”
Although building codes are mostly set by states, the federal government sets codes for manufactured homes (sometimes called mobile homes) because the factory does not always know where a home will end up. Manufacturers shipped 70,519 homes in 2015, more than the number of single-family homes built in any state except Texas.
