Getting Gas Turned On After Inspection in Each Valley City

The building code sets the order of events. Phoenix's administrative code says building service equipment "shall not be connected to the water, fuel, power supply or sewer system until authorized by the building official." Mesa wrote the same idea into its fuel gas code as Section 406.8: "A person shall not make connections from a utility, source of energy, fuel or power to any building or system that is regulated by this code for which a permit is required until authorized by the code official."

The utility clearance is how that authorization reaches the gas company. Maricopa County describes it as the notice "to notify the utility companies that jurisdictional inspections have been conducted and approved prior to energizing electrical systems and introducing natural gas into fuel gas systems and buildings."

Four terms come up whenever gas is off.

• Final inspection. The last inspection on a permit, once the work is complete. Gas turn-on follows it.
• Utility clearance (gas clearance). The city or county notice telling the gas utility the piping passed inspection.
• Locked meter. A meter the gas utility has shut off and locked, for a leak, an unpaid bill or a vacant building, the reasons Phoenix's table lists.
• Master meter system. A property such as a mobile home park, housing project or apartment complex where the operator "purchases metered gas from an outside source for resale" to tenants, who pay through their own meters or in the rent (49 CFR 191.3). Southwest Gas needs a clearance from the Arizona Corporation Commission to restore service to one.

Homes and businesses alike. Phoenix's clearance guide was written by the city, Southwest Gas and the Arizona Corporation Commission for "a residential or commercial application." The county adds a commercial case: it sends temporary gas clearances when a commercial building needs gas to test its fire suppression system before final inspection.

Phoenix's TRT 00930 is the clearest table in the Valley. It lists who inspects and who clears for each situation.

The steps match; the paperwork differs.

Mesa puts the rule in its fuel gas code, so no utility connection happens on permitted gas work until the code official signs off.

Scottsdale lists "Existing natural gas line meter clearance" among the plumbing jobs that need only a Minimum Permit, with no plan review.

Litchfield Park prices it separately: "Gas Test/Clearance Only $50" in its FY2027 fee schedule.

Fountain Hills makes gas part of the final building inspection, which calls for "GAS/ELECT. METERS SET. APPLIANCES OPERATIONAL." Its inspection sheet warns: "IF REQUIRED INSPECTIONS ARE NOT DONE, NO OCCUPANCY WILL BE GIVEN!"

Unincorporated Maricopa County offers "Gas Clearance - No Work Performed" as a web-issued permit, and says "A permit and pressure test is needed to obtain a utility clearance, even if no new work was performed." Clearances "are issued and sent after all final approvals."

The reason for the shutoff decides the path, as these four cases show.

A Phoenix restaurant adds a fryer line. New piping takes a permit and a city inspection, and the city clears the gas after the work passes.

Southwest Gas locks a Phoenix meter after finding a leak in the owner's piping. The repair needs a permit, and the city, not the gas company, inspects and clears it.

A Phoenix apartment complex on a master meter alters its piping. The city inspects alongside the State, and Southwest Gas needs the Arizona Corporation Commission's clearance to restore service.

A county property's gas is off and nothing changed, but the utility asks for a clearance. The county still requires the Gas Clearance - No Work Performed permit and a pressure test before it sends one.

Find out why the gas is off before calling anyone, because that sets the path.

1. 1Check the tag or notice Southwest Gas left, or ask them why the meter is locked.
2. 2If it's a leak or piping work, have a licensed plumber make the repair under a permit from the city or county.
3. 3Get the pressure test and final inspection scheduled by the permit holder. Permit channels vary by city; the gas line permit rules by city page lists them.
4. 4Confirm the clearance went out. The county emails clearances when the inspection result is entered.
5. 5Call the gas utility to restore service once the clearance is on file. As the county notes, "Utility companies have their own requirements, specifications, and inspections."

Most delays come from calling the wrong party first.

• "The gas company can just turn it back on." In Phoenix, not after a customer-side leak or any permitted piping work; the city clears it first.
• "No work was done, so no permit." The county still requires a permit and pressure test for a clearance.
• "An appliance swap needs city clearance." In Phoenix a replacement in kind with no piping changes goes to Southwest Gas.
• "Apartments are cleared like houses." Master meter systems in Phoenix are cleared by the State.

Gas stays off. The county says gas "shall not be introduced into a piping system or appliance without first being tested, inspected and approved," and Fountain Hills withholds occupancy until required inspections are done.
