22 Subcontractors Needed to Build the Average Home

by Crystal Sturgeon


According to a new National Association of Home Builders study, 70 percent of builders generally use between 11 and 30 subcontractors to build one single-family home. On average, a typical builder would use 22 subcontractors to build a house.

Here is a graphical breakdown from the NAHB on subcontractor use:

Data for the study came from the April 2015 survey for the NAHB/ Wells Fargo Housing Market Index, in which a set of special questions were added to contribute data for this study.

These questions asked how often builders subcontracted 23 different jobs. In every scenario, at least two-thirds of the builders said that they would subcontract the job.

The job with the lowest number of builders who would subcontract was finished carpentry, with 68 percent of builders saying that they would always subcontract that particular task.

On the high end of the spectrum, over 90 percent of builders said that they always would subcontract jobs like concrete flatwork, masonry, foundations, HVAC and security systems.

Roughly two-thirds of all builders surveyed sad that they would subcontract out about 75 percent of the construction cost in an average single-family home. The average share of construction costs which were subcontracted was 77 percent.
