A tenant that wants a rail spur, a deep truck court and an interchange within minutes is shopping a short list of places, and Commerce City is on it. We build warehouse and distribution space here for developers and operators who need to move freight by truck and by rail from the same site, with the dock count, clear height and yard geometry fixed before the first footing goes in.
The city's own economic development campaign, dated April 22, 2026, states that Commerce City has two Class I freight rail lines, sits where three major interstates meet and is directly adjacent to Denver International Airport, which is why buyers often compare it with the airport area. Highways reinforce the point: I-76, I-270, E-470 and U.S. Routes 6, 36 and 85 all serve it. For a site selector building a drive-time map, few places collect that many routes in one municipality.
Rail service changes how a building is laid out. A rail-served warehouse needs track-side doors, a loading area that works with car spotting and a slab that handles forklift traffic going in and out of boxcars. We design the site around those movements so rail and truck flows do not collide, and we price both together so the owner sees one number.
Soil, flood maps and a heavy industrial neighborhood
Commerce City adopts its construction code with local amendments, and one of them points to a flood hazard map based on a FEMA study dated March 5, 2007. If a parcel sits near a drainage corridor, that map can influence finished floor elevation, fill and detention, so we pull the floodplain status in the first week. Nearby, beside the Rocky Mountain Arsenal area, sits a refinery that processes 98,000 barrels per day according to the company's website, producing gasoline, diesel and paving-grade asphalt.
Living next to heavy industry has practical effects on construction. Truck routes may be shared with tankers, and air quality and noise expectations from tenants differ from those in a suburban office district. We schedule deliveries to avoid peak industrial traffic, protect finishes from dust and plan wash-down areas on the site so tires from the work area do not track onto public roads.
Rail-served and cross-dock shells
A cross-dock facility turns freight in hours rather than days, which puts weight on door count, staging area and slab thickness at the dock edge. We lay out receiving doors on one side and shipping doors on the other, size the apron for the trailers the operator runs and thicken the slab where lift trucks work hardest. For rail, we coordinate door heights, bumpers and the spur with the railroad's engineering requirements.
The same site often hosts a small office, a driver amenity room and a maintenance bay. A truck terminal may need fuel containment, wash bays and a sloped apron that drains to treatment. We bring the civil engineer, the electrician and the plumber into the design so these items are drawn into the base building rather than added as change orders.
Utilities, paving and concrete beyond the building
Industrial users here usually pay more for what sits outside the walls. Water for fire protection, power capacity for refrigeration or charging, stormwater detention and paving that survives a stream of loaded trailers are all part of our site utilities package. We price those items with the building so the developer is not surprised by a separate utility contractor line.
For high-wear zones we specify industrial concrete floors and heavy-duty yard paving with doweled joints at the dock aprons and in the trailer parking lanes. Rigid paving costs more up front than asphalt, but a yard that does not rut under landing gear is worth it for operators who expect heavy trailer traffic every day of the year.
The 2021 code, 49 amendments and sprinklers in garages
Commerce City adopts the 2021 International Building Code as the City of Commerce City Construction Code, with 49 local amendments. They include sprinklers throughout S-2 parking garages, so a developer planning a structured parking component should ask early. A January 20, 2026 tracker from the Home Builders Association of Metro Denver lists the city on the 2021 IBC, IRC, IEC and IFC with no plans to adopt the 2024 I-codes and an update expected in the 2027 cycle. It is not an official source, so we verify the edition with the city before design is set.
Because the amendments are specific, we read them with the architect before the permit set is finalized. A read like that is cheap compared with a plan review comment late in the schedule. On the energy side, a jurisdiction updating its code after July 1, 2023 must meet an energy standard at least equal to the 2021 IECC under HB22-1362.
Who builds here and what they ask for
The mix is broad. Manufacturing and distribution users want a plant and a warehouse on one parcel, with truck access for both. Building products distributors look for covered storage, long bays and outside yards for lumber and pipe. Parcel and freight forwarders need cross-dock doors and a yard for staging.
Commerce Yards at 96th Avenue and Heinz Way shows the pull. It is a 466,000 square foot, three-building industrial project with rail access in an Enterprise Zone, financed with $77.1 million and scheduled for construction from April 2026 through May 2027. Competing supply like that tells a developer how quickly nearby space may be absorbed, and we use it as one input when we help owners decide between phasing a park and committing to a single large building. Users who want more land and a bit more distance often price Brighton alongside.
Sequencing rail, utility and permit lead times
The long lead items on a rail-served project are not steel or panels. They are the railroad agreement, the utility extension and the permit review. We start those paths first and let the vertical construction schedule float around them. Where a spur connects to an existing railroad line, the railroad's design review and construction windows will govern when track can be built.
For a spec building outside the rail question, the schedule follows the usual pattern: site work, footings, slab, panels, roof and fit-out. We place the slab before winter weather where we can, and carry winter work with temporary heat for finish trades. A single weekly look-ahead keeps rail, utility and building tasks in the same conversation.

Common Questions
Can you build a warehouse that receives rail and truck freight?
Yes. We design the building with rail-side doors on one wall and truck docks on another, and we separate the movements so lift trucks do not cross the track at the same time as trailers back in. The track itself and the connection to the main line follow the railroad's standards, and we coordinate those approvals with the owner.
What are the local code amendments that matter most?
The city's 49 amendments to the 2021 International Building Code include sprinklers throughout S-2 parking garages and a flood hazard map based on a FEMA study from March 5, 2007. Both can affect the base building and site design, so we read the amendments with the design team early.
How should we think about the refinery next door?
For design, it affects truck traffic, noise and air quality expectations. For construction, it affects delivery timing and how we manage dust. We coordinate with neighbors on access and keep haul routes consistent so operations on both sides are not disrupted.
Is rigid yard paving worth the cost?
For a heavy truck court it usually is. Landing gear and tight turning movements damage asphalt quickly. We price a reinforced concrete apron at the docks and compare the lifecycle against asphalt so you can decide with numbers.
How do we compare Commerce City with other metro submarkets?
On rail availability, highway access and distance to the airport, the city performs well. Land cost, tenant labor and availability of ready parcels vary. We build budgets for two or three candidate sites so the owner can compare delivered cost, not just land cost.
