In the 50s and 60s the local gas companies (around us it was NIGAS) would make all type of deals with homeowners and builders. My dad bought a new house in the early 60s very near Chicago but in a close in burb. The builder included a gas line on all of them out to the front yard and nearly every one of them had a gas lamp on a post. Also nearly every house had a copper gas line plumbed out the back door and IIRC an Embermatic on a post included right outside the back or the side door next to the driveway on the kitchen side.
My dad got neither (though the lines were there) as he'd begged borrowed and scraped every single dime to make a 10% down payment on a $21900 house. He had to end up doing a lot of finish work on himself floors in lower level, driveway, garage, all the bath tile and so on.
But with my grandfather and 3 of my uncles in the trades and them also knowing friends he got everything done.
All this was to save about $3 or $4k on the cost of the house.
