ISTA Engineers is headquartered in Denver and prepares PE-stamped structural plans, inspections, and reports for projects across Colorado, from Front Range suburbs to mountain towns.

Every jurisdiction adopts its own code edition and local amendments, so we confirm the governing code, snow load, and soil conditions for each address rather than relying on generic assumptions. Ground snow loads run roughly 30 psf in the Denver metro area and 40 to over 100 psf in mountain communities, and expansive clay soils are common along the Front Range.

How We Work Across Colorado

  • Local code first. We confirm the adopted code edition and local amendments for your jurisdiction before designing, so the stamped package matches what the plan reviewer expects.
  • Site conditions, not averages. Snow load, frost depth, and soil conditions are checked for your actual address, from Front Range clay to high-country snow.
  • One team for your project. We coordinate directly with your architect, general contractor, landlord, or builder so the structural scope keeps the permit moving.

Areas We Serve FAQ

Which areas does ISTA Engineers serve?

ISTA Engineers serves homeowners, builders, architects, and property owners across Colorado, including the Denver metro area, the Front Range, and mountain communities such as Aspen, Vail, and Breckenridge. The city pages above list the services available in each area.

Do you work in mountain towns like Aspen, Vail, and Breckenridge?

Yes. Mountain projects are designed for the higher ground snow loads and local design review common in those towns, and several of our services have dedicated pages for them.

My city is not listed. Can you still help?

Yes. The list shows cities with dedicated pages, not the limit of our service area. Contact us with your address and project, and we will confirm the governing code and scope.

Are the plans accepted by my local building department?

We prepare PE-stamped, permit-ready drawings and calculations tailored to the requirements of the jurisdiction where the project is built, and we respond to plan-review comments.
