I believe that’s how my parents’ house is in rural PA, but I had mine surveyed during a neighborly dispute and it ends at my retaining wall, behind the sidewalk. So everywhere is probably different. Possibly even within the city.

Side note, I used to talk shit about people who walk on the road when there’s a perfectly good sidewalk along the street, until I started going for walks in my neighborhood. You don’t know street to street if you’re going to get a walkable sidewalk, or any sidewalk at all. Then you get a random post-war street in places like Marshall-Shadeland (Ridgeland and Newhampshire drives , and Ingram to note) with random to no sidewalk at all like it’s Pleasant Hills. So now, I have an understanding of the street walking in certain situations. But that also had me wondering about the ownership of sidewalks. I bet the streets I mentioned own at least out to the road. So who made it okay to have no sidewalk when planning these?

Overall, I bet it’s an old oversight. They were probably officially part of city infrastructure at one time, until they realized they wouldn’t be able to legitimately maintain them.
