Frequently Asked Questions
What is the average cost per square foot to build a house?
In the US, new home construction typically ranges from $130-$160/sq ft for economy builder-grade homes, $170-$240/sq ft for standard custom homes, and $260-$450+/sq ft for high-end luxury.
Why should I include a construction contingency?
Unforeseen site conditions, plumbing changes, material price fluctuations, and design modifications commonly occur. A 10-15% reserve prevents project halts.
