The stage ranges are typical for a contractor-built 2,000 sq ft home. Stages overlap on a well-run project. See all steps to building a house.

Why do custom homes take longer?

Custom homes take longer because the owner makes more decisions during the build, plans are one-off rather than repeated, and the builder is managing one project instead of a production schedule. A builder building the same plan 50 times a year can finish faster than one building a unique home.

What delays building a house?

The most common delays are:

  1. Permits and inspections backed up in busy counties.
  2. Weather, especially during foundation and framing.
  3. Material shortages for windows, electrical gear and appliances.
  4. Labor shortages in skilled trades.
  5. Change orders when the owner changes the design mid-build.
  6. Financing: draw inspections and paperwork between stages.

What is the fastest way to build a house?

The fastest options are a modular home, built in a factory while the site is prepared, or buying a spec home already under construction. A builder’s standard plan with standard finishes is also faster than a custom design.

How does build time affect cost?

A longer build costs more in construction loan interest, extension fees and rent. On a $400,000 loan at 8.5%, each extra month near the end of the build costs close to $2,800 in interest. Model it with the construction loan calculator.
