Labor costs to build a new house are likely to go up, whatever the outcome of the immigration reform legislation currently under consideration in Congress. In 2005, builders spent 15 percent to 20 percent of the $381 billion they made in new-home sales on construction labor. Factor in Pew Hispanic Center's estimates of about 14 percent of the construction labor force being illegal, and that works out to about $8 billion to $11 billion on illegal labor. If the costs for undocumented workers are adjusted to reflect what it probably will cost to do the jobs with legal workers, economists estimate that builders will pay as much as much as $4 billion to $5.5 billion more nationally. What does it mean to you? Here's a drill-down of the costs associated with illegal labor for a $200,000 home versus a $500,000 home.
