The City of Maricopa lists Southwest Gas as its gas utility, so a gas smell means leaving the house and calling 911 and Southwest Gas at 877-860-6020. For repairs and additions on your side of the meter, call the number on this page to be connected with a local plumber in Maricopa.

Maricopa incorporated in 2003 and grew fast, with residential subdivisions spreading out from State Route 347. The median home was built around 2007, and roughly 63 percent of homes went up between 2000 and 2009. That means most gas systems in the city were installed in the same decade, often with flexible stainless tubing and builder-sized lines. The City's Building Safety division administers the plumbing and mechanical codes and takes digital submittals through its VIP Portal.
Steps to take
- Odor in the house: go outside right away and leave doors open behind you if it's easy to do on the way out.
- Make the calls from the street or a neighbor's yard: 911 and Southwest Gas at 877-860-6020.
- Stay out until Southwest Gas or the fire department says it's safe.
- Book a plumber for the piping repair once the gas is shut off.
- For upgrades, list every gas appliance you have and plan to add, so the system can be sized once.
What the symptoms usually mean
| Symptom | Likely cause |
|---|---|
| Tankless heater flames out under load | Gas line or meter undersized for the unit |
| Faint smell at the dryer | Connector disturbed when the dryer was moved |
| Yellow tips on cooktop flames | Burner needs cleaning or adjustment |
| Hissing near a valve | Worn valve packing or a loose joint |
What affects cost
- Upsizing builder-installed tubing when a tankless heater or pool heater is added
- Attic access and summer heat in single-story homes
- Trench length for outdoor appliances
- Bonding work on flexible tubing if it was never connected
- Permit and inspection through the city’s VIP Portal
Because so much of Maricopa was built at once, neighbors often have the same layout. If a neighbor had trouble with a particular connection, it is worth having yours looked at too.
When you call the number on this page, you reach an independent plumber who takes gas work in Maricopa. Mention the subdivision, the appliance involved and whether the job includes any digging. For a tankless conversion, have the model number ready so the plumber can compare its maximum gas input with what the existing tubing and meter can deliver. Ask how the permit and inspection fit into the schedule, and plan for the gas to be off for part of the visit while the system is tested.
