Does anyone know how much it cost to add a gas meter to an ADU?

[Victor G.]

I got this house were I'm converting the attached garage into a granny flat (ADU). I'm wondering what the cost to add another gas meter to the existing one? I'm essentially making a SFH house into a duplex with this garage conversion. ...just wondering if it's worth going with gas (for dryer, tankless water heater, range). I've heard an (2022) estimate cost of a few thousand to ten thousand for installation and permitting. Anyone have any input??
