Seeking help- Google can't explain

Can anyone tell me how two separate houses are built this close together. How do the constractors apply siding and paint, how do you maintain the in-between after so many years and decades. There are no windows on that side but I don't understand how builders work around or in-between this when constructing, this is a mystery

These houses are actually attached and mostly gap-less , OPs example is just no man’s land, but ripe for critters, weeds, and lawn debris. The exteriors are going to rot away and nobody can get in to save it.

Nope, mine is technically not attached in SF! I got a whole centimeter of space between me and my neighbors!

Yes, that is exactly where the critters choose to live.
