Yes, most states require a plumber to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. Check our state licensing tool to review the local plumber guidelines.

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification, which include:

• The owner, principal, or relevant manager passed a criminal background check

• Required to have applicable state and local licenses

• Maintain an average star rating of 3.0 or better on our network, if they have at least one review

• Paying to advertise their services

• Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

All U.S. states require permits for gas grill installation, so you’ll have to get one before you move forward with your project. Permits help ensure that the gas line runs safely to avoid gas leaks and explosions. Gas line permits can usually also only be pulled by certified plumbers, which means you’ll have to hire a professional from the start. The permit for a gas line installation for a gas grill usually costs between $100 and $300. You can contact your installation company or building department for more accurate pricing.

DIY is not recommended due to safety concerns. Professional installation ensures proper connections and compliance with codes.

Depending on the appliance and labor requirements, costs range from $150 to $500.
