Sorry, we definitely have different definitions of townhomes. Where I am from (NYC) a townhouse is typically a 2/3 story build, narrow. With 2/3 units or sometimes split down the middle giving you 4 or 6 units or as high as 12 usually, often with an english basement and a back yard.

This is what I am talking about https://streeteasy.com/blog/types-of-townhouses-in-nyc/

DC is full of them too, so is boston. Googling NYC Park Slope Townhouse would get you tons of images of nicer ones, but there's tons of cheap vinyl sided ones that are just fine.
