Remodeling Contractor in Commerce City, CO

Single-story ranch homes on a residential street in Commerce City, Colorado — illustrative reference image, not a project photo.

Commerce City is really two housing markets sharing one city government. There is the historic core — the old Commerce City and Adams City neighborhoods that predate the city’s 1952 incorporation — and there is the master-planned north, Reunion and the Villages at Buffalo Run, built essentially from scratch after 2000. A remodeling scope that makes sense in one is often irrelevant in the other, and pricing that ignores which side of the city you are on is guesswork.

The City Issues Your Permit, Not Adams County

Commerce City runs its own Building Safety Division inside its Community Development Department, and it permits residential work throughout the city. Adams County’s building department has no role inside city limits — it covers unincorporated county land only.

The city has adopted the 2021 International Building Code, codified locally as the City of Commerce City Construction Code, with its own selection of appendix chapters and referenced standards. That local codification matters: this is not a generic adoption, it is the city’s own construction code, and the authoritative text lives in Chapter 5 of the municipal code.

Contractor licensing is required. Licensing runs through the city’s eTRAKiT portal and includes a current certificate of general liability insurance naming the City of Commerce City as certificate holder. That last detail catches out-of-town contractors regularly — a certificate made out to the homeowner or to another jurisdiction does not satisfy it, and the license does not issue until it does. Ask any contractor bidding your Commerce City project whether they are already licensed here.

The Old Core

The area that became Commerce City was farmland — wheat, dairy, hogs — into the late 1920s. The refinery arrived in 1930. The Rocky Mountain Arsenal was built by the Army in 1942. The city incorporated in 1952 and annexed part of Derby roughly a decade later.

So the original housing here is genuinely old by metro-Denver standards, and all of it sits on the wrong side of 1978. That triggers the EPA’s Renovation, Repair and Painting rule on any work disturbing painted surfaces — certified firm, contained work area, verified cleanup. Asbestos belongs in the same conversation: popcorn ceilings, sheet vinyl and its mastic, duct wrap and period joint compound routinely test positive in Colorado houses of this age, and CDPHE Regulation 8 sets the thresholds where abatement stops being optional. We test before demolition. Discovering it mid-demolition stops the job and moves both the schedule and the price.

The rest of the old-core list is what you would expect from houses that have been lived in for sixty to ninety years: undersized electrical service, mixed generations of plumbing, sewer laterals with root intrusion, additions built at various times to various standards, and framing that has been modified more than once without documentation. This is workable — it is most of what we do — but it is why a fixed price quoted without opening anything is a number someone intends to revise later.

Reunion and the Villages at Buffalo Run

North of the airport corridor the picture inverts. These are master-planned, HOA-governed subdivisions built from the early 2000s onward. No lead paint, no asbestos, no mystery framing.

What these houses do have is a builder-grade envelope now reaching twenty years of Colorado weather: original roofs on their second or third hail claim, windows and seals at end of service life, deck framing and fasteners due for inspection, and original HVAC equipment reaching replacement age. And they have an HOA. Architectural review here is a real step with a real timeline — exterior color, roof material and profile, deck design and fencing typically all require approval, and approval runs in parallel with the city permit, not after it. We plan for both.

The Arsenal and the Refinery

Two facts about Commerce City have no equivalent in the neighboring suburbs.

The Rocky Mountain Arsenal manufactured chemical warfare agents from 1942, and Shell leased part of the site to manufacture pesticides from 1952 to 1982. It was listed on the EPA Superfund National Priorities List in 1987, cleanup completed in 2010, and 917 acres of delisted land were sold to the city for commercial development, with the remainder held by the Army for ongoing water treatment. The site is now a National Wildlife Refuge.

The Suncor refinery — built in 1930, acquired by Suncor in 2003 — is still an operating refinery inside city limits.

For a homeowner planning a remodel, neither of these stops a project. What they mean practically is that environmental questions here get asked and answered rather than waved off, particularly on properties in the refinery corridor and on parcels with a history of industrial or commercial use. If you are buying and remodeling in these areas, the environmental record of the parcel is part of due diligence, not an afterthought.

Soil, Radon and the South Platte

The Colorado Geological Survey identifies expansive soil as Colorado’s most damaging geologic hazard, with swelling bentonite and montmorillonite clays underlying roughly a third of the state’s homes across the populated Front Range. Commerce City sits in that landscape. In a house it shows up as seasonal slab movement, which is why basement framing here should float — a deliberate gap at the top of the wall — and why a basement drywall crack that reopens each spring in the same corner is a drainage and framing problem rather than a finishing one.

Adams County is in EPA Radon Zone 1, the highest zone. Test before finishing a basement; mitigation is cheap while the slab is exposed and disruptive afterward.

The South Platte River runs through Commerce City, which means flood mapping is a live question for parcels near the river corridor. Parcel-level flood zone is determined by the FEMA Map Service Center, not by assumption, and it is worth checking before you plan a basement finish or a ground-level addition on a riverside lot.

How We Run a Project Here

We hold city licensing with insurance issued to the city’s requirements before we bid, so licensing never becomes the reason a start date moves. We pull permits in our name, not yours — a homeowner-issued permit moves liability onto the homeowner, and that is one of the quiet reasons a cheap bid is cheap. On pre-1978 houses we test for lead and asbestos before demolition. In HOA neighborhoods we run architectural review in parallel with the city permit. And we open a wall before pricing anything whose cost depends on what is inside it.

Derby

Derby is the original commercial heart of Commerce City, centred on East 72nd Avenue, and it is inside city limits — so permits, inspections and zoning review all run through Commerce City rather than Adams County. The housing around it is mostly small post-war single-family stock on compact lots, which is why the work we do there leans toward kitchen and bathroom reconfiguration, basement finishing and additions that have to respect tight setbacks.

Common Questions

Do I get my permit from Adams County?

No. Inside Commerce City limits, the city’s own Building Safety Division issues residential permits under the City of Commerce City Construction Code, which is based on the 2021 International Building Code. Adams County permits unincorporated county land only, though the county remains your assessor and tax jurisdiction.

Does my contractor need a Commerce City license?

Yes. Contractor licensing is required and runs through the city’s eTRAKiT portal, including a current general liability certificate that names the City of Commerce City as certificate holder. A certificate issued for another jurisdiction will not satisfy it, so confirm licensing before signing a contract rather than after.

Does the old Rocky Mountain Arsenal affect my remodel?

Not directly. The site was listed on the Superfund National Priorities List in 1987 and cleanup was completed in 2010, with 917 acres of delisted land sold to the city and the remainder retained by the Army for continued water treatment. What it means in practice is that parcel history and environmental records are worth reviewing during a purchase, particularly on formerly industrial or commercial land.

My house is in Reunion. Do I still need approvals beyond the permit?

Almost certainly. Reunion and Villages at Buffalo Run are HOA-governed, and exterior work — roofing material and color, paint, decks, fencing — typically requires architectural review. That review runs alongside the city permit rather than after it, and building it into the schedule up front avoids a stalled project.

Should I test for radon before finishing my basement?

Yes. Adams County is EPA Radon Zone 1, the highest zone. A sub-slab depressurization system is inexpensive to install while the slab is exposed and the walls are open, and expensive to retrofit into a finished basement.
