General Contractor in Louisville, Colorado

We are a general contractor in Louisville, Colorado, building fire-hardened homes, Marshall Fire rebuilds, additions and renovations in Old Town. Louisville sits in southeastern Boulder County at about 5,400 feet. It began as a coal mining community in 1877 and incorporated in 1882, and both of those histories, the mines and the town that grew over them, still matter to anyone building here. So does the Marshall Fire.

Rebuilding after the Marshall Fire

On December 30, 2021, the Marshall Fire swept through Louisville, Superior and unincorporated Boulder County, destroying and damaging more than 1,000 homes and more than 30 commercial structures, according to Boulder County. NOAA's windstorm log for that day lists gusts of 115 mph in Arvada and 110 mph at Rocky Flats, and it records a 93 mph gust near Louisville just two weeks earlier, on December 15. As of December 1, 2025, Boulder County reported 931 building permits issued for the recovery, about 84 percent, and 829 certificates of occupancy, about 75 percent.

Rebuilds have rules of their own. A Marshall Fire rebuild Design Criteria and Prescriptive Energy Code path is available, but only to original owners. New landscaping standards apply within the first five feet of homes in rebuild areas, posted February 3, 2026.

Codes and the Fire Hardening Code

The City of Louisville Building Safety Department adopted the 2024 International Building, Residential, Energy Conservation, Fire, Plumbing, Fuel Gas, Mechanical, Existing Building and Property Maintenance Codes with local amendments, effective December 6, 2025, together with the Colorado Model Electric Ready and Solar Ready Code. The 2023 National Electrical Code is adopted with a local amendment requiring GFCI protection on all new outdoor air conditioning units, and RESNET HERS standards verify residential energy compliance.

The code has changed three times in roughly a year, so drawings prepared even a few months ago need rechecking against the current version before they are submitted.

Coal mines under the ground

The Colorado Geological Survey has studied coal mine subsidence in the Boulder-Weld coalfield, which runs under parts of Boulder and Weld counties. It notes that development has moved into undermined areas and that the amount and area of subsidence cannot be predicted with certainty from available records. It also maps potentially swelling soil and rock across the Front Range corridor. On a Louisville lot, the geotechnical investigation looks for both, and the foundation design follows what it finds.

Old Town and its preservation tax

In November 2008, Louisville voters approved the nation's first local sales tax dedicated to historic preservation, spent only within historic Old Town and extended in 2017 through 2029. Grants and loans are available for landmarked residential and commercial properties, and the program is voluntary, guided by a master plan adopted in 2015. For an older house on or near Main Street, landmarking can open funding for the renovation itself.

What we build in Louisville

Our Louisville work includes rebuilds and new homes to the current hardening code, custom homes, and Old Town renovations. Each one starts with the code version, the energy path and the ground, settled before the design is priced.
