Do this before troubleshootingLeave the building. Do not use switches, flames, appliances, or a phone indoors. From outside, call 911 if there is immediate danger and call your gas utility. Do not re-enter until responders say it is safe.
The short answer
Responsibility can vary by equipment and local utility practice. A contractor should not work on utility-owned components, and a utility may shut off service until private-side repairs and tests are complete.
What matters in this situation
Odor, hissing, or a detector alert changes the order of operations: protect people first, then diagnose the private-side piping after the utility or emergency responders say the area is safe.
Details that help define the next step
- Where the utility marked the leak
- Meter and shutoff status
- Written utility instructions
- Whether the issue is at an appliance, branch, manifold, or buried private line
These details help establish scope; they do not replace an emergency response, onsite inspection, utility decision, permit requirement, or manufacturer instruction.
How a careful service process is organized
- Start by documenting where the utility marked the leak and meter and shutoff status.
- Confirm written utility instructions and whether the issue is at an appliance, branch, manifold, or buried private line before the scope is finalized.
- Have utility case number and photos of tags and marked locations ready for the onsite team or authority.
- Use the findings to define the appropriate emergency gas leak repair scope, required testing, and any next authority or trade.
What to have ready when requesting service
- Utility case number
- Photos of tags and marked locations
- Property piping records
- Access to the meter and affected equipment
What not to do
Do not hire anyone to alter the meter or upstream service piping. Keep relevant tags, notices, equipment information, and safely obtained photos available for the people handling this specific situation.
