Steel & concrete modular homes in Colorado
Modular homes are built to state and local building codes and set on a permanent foundation. Here is what applies in Colorado.
Colorado program
- Administering agency
- Colorado Division of Housing (DOLA), Office of Regulatory Oversight, Building Codes and Standards section
- Program / authority
- Factory Built Structures program (residential and nonresidential)
- Code basis
- Not verified. Confirm with the local building department.
- Inspection & seal
- Division of Housing reviews and approves factory-built plans, inspects, and certifies structures; installers register and post an Installation Authorization form.
- Good to know
- Local governments may not duplicate DOH plan review or charge permit fees for it; DOH handles foundation approval where no local building department exists (since 7/1/2023).
