Denver Natural Gas Connection Guide for Small Businesses

Utilities and Infrastructure Colorado 3 Minutes Read · published February 07, 2026 Flag of Colorado

Connecting natural gas for a small business in Denver, Colorado requires coordination between the city building/inspection system and the utility provider, plus properly licensed contractors. This guide explains the typical steps, permits, inspections, timelines, and enforcement contacts that Denver businesses need to open or convert a commercial gas service.

Overview: Who does what

In Denver the utility (natural gas provider) handles service delivery and meter installation while the City of Denver issues permits and inspects gas piping and appliances inside buildings. Start with the utility to request a new service evaluation, then apply for required mechanical or building permits with Denver Community Planning and Development for onsite gas piping and appliance work.[2][1]

Contact the gas utility early to confirm service availability and meter location.

Step-by-step actions for small businesses

  • Contact the natural gas utility to request a new service application and site evaluation. [2]
  • Hire a licensed mechanical contractor experienced in commercial gas piping.
  • Submit mechanical or building permit applications to Denver Community Planning and Development for gas piping, appliances, and any associated venting or structural work.[1]
  • Schedule required inspections with the City after installation is complete; the utility typically will not set a meter until city inspections pass.
  • Pay permit fees and any utility charges (meter set, service line, capacity fees) as required by the provider and the city.

Applications & Forms

The City of Denver accepts online permit applications through its permits portal for mechanical and building permits; specific mechanical permit forms and submission instructions are available on the Denver permits page. If a required form, application number, or fee schedule is not listed on the cited city page, it is not specified on the cited page.[1]

Penalties & Enforcement

Unauthorized or unsafe gas work can lead to enforcement by Denver Community Planning and Development and fire code enforcement. Monetary fines and other sanctions depend on the specific code violation; if fine amounts or precise escalation formulas are not published on the cited page, they are not specified on the cited page.[3]

  • Monetary fines: not specified on the cited page.
  • Escalation: first, repeat, or continuing offences and daily continuing penalties are not specified on the cited page.
  • Non-monetary sanctions: stop-work orders, orders to correct unsafe conditions, permit revocation, or court action may be used by city enforcement.
  • Enforcer and inspections: Denver Community Planning and Development - Permits and Inspections unit handles permit compliance and inspections; fire code enforcement may also inspect for gas safety and appliances.[1]
  • Appeals/review: specific appeal routes and time limits are governed by city procedures or code; if a time limit for filing an appeal is not published on the cited page, it is not specified on the cited page.[3]
Always stop work immediately if an inspector declares a safety hazard.

Common violations and typical outcomes

  • Working without a required mechanical or building permit — may prompt stop-work order and required re-inspection.
  • Improper gas piping or unsupported/unapproved fittings — corrective orders and re-inspection required.
  • Unapproved appliance installations or venting — removal or modification and additional permits.

How-To

  1. Contact the natural gas utility to request a new commercial service estimate and meter-siting visit. [2]
  2. Obtain written service requirements from the utility (service line depth, meter location, capacity requirements).
  3. Submit permit applications to Denver Community Planning and Development for mechanical and any associated building work; upload plans and contractor license information as required.[1]
  4. Have licensed contractor complete installation to the approved plans and code standards.
  5. Schedule and pass city inspections; after approval, coordinate with the utility for final meter set and service activation. [2]
Inspections must pass before the utility will connect and set the meter.

FAQ

Do I need a permit to install commercial gas appliances?
Yes. Commercial gas piping and appliance installations generally require mechanical or building permits from Denver Community Planning and Development; confirm on the permits portal.[1]
Who sets the gas meter?
The utility provider installs and sets the meter after the city inspections are complete and any utility requirements are met.[2]
Can I apply for service before I get a building permit?
You can request a utility service evaluation and application, but the utility often requires that city permits and inspections for onsite piping are completed before final meter set.[2]

Key Takeaways

  • Start with the utility for service feasibility and meter requirements.
  • Apply for Denver mechanical or building permits before installation.
  • Pass city inspections before the utility will set the meter and activate service.
