If you have recently had gas line work done or are purchasing a home in Utah, a gas line inspection may be required — either by your city building department (for permitted work) or by your own initiative for peace of mind. Knowing what to expect and how to prepare makes the process smooth and helps you pass on the first visit.
When Is a Gas Line Inspection Required in Utah?
In Utah, a gas line inspection is typically required in the following situations:
- After any permitted gas line work: When a licensed contractor pulls a permit for new installation or significant repair, the work must be inspected and approved before the gas line is put into service
- Home purchase: While not always legally required, a gas system inspection before buying a home is strongly recommended, especially for older properties
- After a gas leak or emergency shutoff: Before gas service is restored after a leak-related shutoff, the gas utility or building department may require an inspection
- Rental property inspections: Some municipalities require periodic inspections of gas systems in rental units
- Insurance requirements: Some homeowner’s insurance policies require documentation of a gas system inspection, particularly for older homes
Who Can Perform a Gas Line Inspection in Utah?
For permitted work, the inspection is performed by a licensed building inspector from your city or county. In some cases, the gas utility (Dominion Energy in most of northern Utah) may also inspect work that affects the service connection.
For pre-purchase or voluntary safety inspections, a licensed gas line contractor like The Gas Pipefitter can perform a comprehensive inspection of your entire gas system and provide a written report.
What Does a Gas Line Inspector Check?
A thorough gas line inspection covers several key areas:
1. Pressure Testing
The inspector will perform a pressure test on the gas line system to verify there are no leaks. This involves pressurizing the line (typically with air or nitrogen for safety) and monitoring for pressure drop over a set time period. Even a small drop indicates a leak somewhere in the system.
2. Pipe Condition and Material
The inspector will visually examine exposed pipe runs for signs of corrosion, damage, improper support, or unapproved materials. Flexible connectors behind appliances are a common inspection focus point — older connectors (especially uncoated brass or aluminum) may need replacement.
3. CSST Bonding Compliance
If your home has CSST (flexible yellow gas tubing), the inspector will verify it is properly bonded to the home’s electrical grounding system, as required by code in Utah.
4. Shutoff Valves
Each gas appliance should have a dedicated shutoff valve within reach of the appliance. The inspector will check that these valves are present, accessible, and in working condition.
5. Appliance Connections
Connections between the gas supply line and each appliance will be checked for proper installation, correct connector type, and absence of leaks. Rigid pipe connections are generally preferred over flexible connectors where the appliance does not require movement.
6. Pipe Penetrations and Clearances
Where gas lines pass through walls, floors, or ceilings, proper sleeves and fire stopping must be in place. The inspector will also verify clearances from electrical panels, water heaters, and other potential ignition sources.
7. Meter and Regulator Condition
The gas meter and pressure regulator (usually located outside) will be checked for damage, proper venting, and code compliance. Regulators have a service life and may need replacement on older systems.
How to Prepare for Your Gas Line Inspection
Whether you are preparing for a required permit inspection or a voluntary safety check, these steps will help ensure a smooth process:
Make Sure All Work Is Accessible
Do not drywall over or cover any new gas line work before the inspection. Inspectors need visual access to verify the installation. If work has been covered prematurely, you may be required to open walls — an expensive and inconvenient mistake.
Have Your Permit and Plans Available
For permitted work, keep your permit paperwork accessible and have any approved plans available at the job site. Inspectors reference the approved plans to verify the work matches what was permitted.
Know Where Your Shutoffs Are
Be prepared to show the inspector where your main gas shutoff and individual appliance shutoffs are located. This demonstrates that the system is safely accessible and helps the inspection move quickly.
Leave Appliances Accessible
Do not push appliances against the wall on inspection day. Inspectors need to access the connections at the back of stoves, dryers, and other gas appliances. Pull them out from the wall beforehand.
Address Known Issues Beforehand
If you already know about a problem — such as a flexible connector that looks worn or a shutoff valve that is hard to reach — get it fixed before the inspection. Scheduling your licensed contractor to make these corrections in advance is much easier than failing an inspection and rescheduling.
Be Present for the Inspection
Try to be home during the inspection so you can answer questions and receive feedback directly from the inspector. This also ensures you understand any corrections required.
What Happens If You Fail a Gas Line Inspection?
If the inspector identifies code violations or failures during pressure testing, they will provide a list of required corrections. You will need to make those corrections and schedule a re-inspection before the gas line can be placed in service. Your licensed contractor should be able to address most common inspection failures quickly.
Common reasons for failing a gas line inspection include:
- Failed pressure test (indicating a leak somewhere in the system)
- Missing or inaccessible shutoff valves
- Unpermitted work or work that does not match approved plans
- Ungrounded CSST
- Improper pipe support or clearances
- Use of unapproved materials or fittings
