Your natural gas meter should be mounted outside your home where the gas service line comes up from the ground to your meter, on the side or the rear. If you live in an apartment or other multi-unit dwelling, typically the meters will be grouped together in a meter bank, each labeled with a unit number.
From time to time, maintenance may be required to your meter or service line. It is important to have safe and clear access to your service line and meter. Avoid landscaping or fences and remove any overgrowth around your natural gas equipment.
