What Commerce City homes are working with
Commerce City grew out of farmland after industry arrived in the late 1920s, and it still has an industrial core next to its neighborhoods. The southern part of the city, around the Civic Center at 60th Avenue and Trenton Street, has older homes where gas piping may have been patched and extended over decades. North of East 96th Avenue the subdivisions are much newer, with flexible tubing and modern appliance layouts.
The city lists Xcel Energy (Public Service Company of Colorado) as its gas provider. Electric service is split, with United Power covering parts of the city, but that affects only electricity. Gas leak calls go to Xcel at 1-800-895-2999.
The Building Safety Division handles permits and inspections through the eTRAKiT portal and lists water heater replacement as work that can need a permit. Call Building Safety at 303-289-3790 if you are unsure about a particular gas job.
Common jobs and what they involve
| Job | What the plumber does | Permit likely? |
|---|---|---|
| New gas range or dryer | Sizes and runs a branch, adds a shutoff, tests | Usually |
| Water heater swap | Reconnects gas, checks venting and line size | Can be required |
| Leak at a fitting | Finds it, repairs it, retests | Depends on scope |
| Garage heater or shop line | New run, often longer, with shutoff | Usually |
Signs something is off
- Odor of gas: leave first and call from outside
- Hissing near the meter or an appliance valve
- Yellow or lazy burner flames
- Soot marks around vents
- A gas bill that rises without a reason
Seasonal notes
Colorado's big temperature swings mean furnaces cycle often from October into spring. If you have noticed any of the signs above during summer, have them checked before the heating season starts. Garage and shop heaters that sat unused all summer deserve a look before the first cold week, since connectors and venting on those units are often neglected. If you are planning to replace a water heater, check with Building Safety about the permit before the old unit fails so a planned swap does not turn into a rushed one. For any outdoor or buried line, schedule the trenching before the ground freezes.
If a gas appliance is being added in a garage that also houses vehicles, mention it, since codes set rules for burner height and protection in garages.
