Yes, like most countries it varies by region mostly because of the history of the area. I’m from the Deep South and grew up in a ‘shotgun’ styled house built in the early 30s. You see this style most famously in cities like New Orleans. Many of the original homes of this style are sometimes remodeled to a certain degree with new siding and a metal roof although some still retain their original asphalt shingle siding, which I love. My town, which is very small (pop. >300) and economically depressed, is full of them and on the rare occasion that a modern home is built here it stands out like a sore thumb. The ‘nicer’ houses built around the same time period, if they’ve survived, have basements or very high crawl spaces as this is a flood plain of the Mississippi River, and the 1927 Flood devastated the area. This style is less common but there are a few examples here and many more in other towns nearby.
I looked up shotgun house. Interesting.
Sidenote: you said your town is about 300 people? What do you do for work there? Or do you work remote?
I’m a sysadmin, I drive an hour to a larger town everyday.
In my city there are a couple notable examples: the four square house, the bungalow, the craftsman, the row house, and older victorian houses. They were extremely popular because you could order the entire house from sears mail order (for ~$2000 back then, equivalent to only around $50k today!). The victorian houses were more custom crafted and ornate, although a lot of the others are dressed up with victorian trimmings and multiple different paints.

His architecture is postmodern, inspired by vernacular perhaps, but not vernacular itself.
