The average cost of building a 300-square-foot house is $15,000, according to the U.S. Department of Energy’s Building America program. This amount does not include the land or any of the appliances or fixtures.
The price for a new home varies greatly depending on the location and size of your lot. If you choose to use all volunteer labor, there will be no additional costs involved, but if you need to hire out some jobs like plumbing or electrical work, expect to spend anywhere between $4,000-$7,000 depending on the complexity of your project and whether you hire a contractor who specializes in small house construction or simply do it yourself.
Cost to build 300 sq ft house
If you want to know how much it costs to build a house, you can get an idea by looking at the price per square foot for local builders.
The average cost of building a home in the United States is about $200 per square foot, which is just a little less than $20,000 for a 2,000-square-foot home.
The cost of building a new home varies greatly depending on where you live and how big your house needs to be. In some cities, like Los Angeles or San Francisco, it’s possible to spend more than $1 million on a new home that’s only 2,000 square feet. In other cities like Omaha and Wichita, it’s possible to build an entire house for less than $100 per square foot — less than half the national average!
But realistically speaking, most people are looking at spending between $150 and $250 per square foot on their new home — with prices ranging from around $150 per square foot in smaller cities like Wichita up to as much as $250 per square foot in larger cities like New York City or San Francisco.
