General Contractor in Erie, Colorado

We are a general contractor in Erie, Colorado, building new homes, additions and renovations from Historic Downtown on Briggs Street out to the newer neighborhoods. Erie sits in the southwest corner of Weld County and reaches west into eastern Boulder County, at roughly 5,100 feet. Its first official underground coal mine opened in 1876 and its last, the Eagle Mine, closed in 1978. The town that grew over those mines now runs a building program with an unusual mix of code editions, and that is where our planning starts.

Two code editions at once

The Town of Erie Building Division issues building permits and describes itself as a one-stop shop for property improvements. Erie's adopted codes are not all from the same cycle. The building, residential, mechanical, plumbing, fuel gas, existing building, property maintenance and pool codes are the 2021 editions. The energy code is the 2024 International Energy Conservation Code with local amendments, adopted by Ordinance No. 12-2026, approved April 14, 2026 and effective April 24, 2026, along with the 2026 National Electrical Code and the 2024 International Fire Code as adopted by the Fire District.

One town, two counties

At the 2020 census, about 58 percent of Erie residents lived in Weld County and 42 percent in Boulder County. Inside town limits, the Town of Erie Building Division handles permits on both sides of the county line, so the county mostly matters for property records and for parcels just outside town, which fall to the county. Confirming that a lot is actually inside town limits is still the first step, especially near the edges.

A century of coal mining

Most of the area's mines closed by 1960, but the history runs from 1876 to 1978. Erie sits in the Boulder-Weld coalfield, which the Colorado Geological Survey has studied for subsidence. The survey notes that development has moved into undermined areas, that the amount and area of subsidence cannot be predicted with certainty from available records, and that damage from subsidence over inactive coal mines is not covered by standard homeowner insurance. That combination makes the ground investigation the most important early decision on an Erie lot.

Soils, hail and the airport

Beyond the mines, the Colorado Geological Survey maps potentially swelling soil and rock across the Front Range corridor and recommends site-specific soils testing to confirm conditions on a given lot. The Colorado State Library, citing Colorado Climate Center records, notes frequent summer hail along the Front Range. Erie also owns and operates an airport: Erie Municipal Airport sits on Colorado Highway 7, a little over three miles west of I-25. For sites near it, we check early whether the airport affects what can be built.

What we build in Erie

Our Erie work centers on new homes and additions and renovations, from Old Town to the newer subdivisions. Every project starts with pre-construction: the town boundary, the code edition for each discipline and what is known about mining beneath the lot.
