i mean, do you literally mean how is this "permitted?" i would look to the local municipal codes, etc.
are you talking about the small gap and the fact that the firewall isn't closed? houston may be unique in that they are building new construction that leaves gangways like that, that can't be walked down. generally speaking new zero lot line construction closes that gap...it was common in the 19th century in the u.s. to leave varying width gangways like that smaller than what a man could walk down in the older cities of the midwest but not as common now...it's usually like 3 feet (or whatever) or completely closed.

Basically wouldn't a tiny gap like that mean that replacing the sheathing basically be impossible in the case of water infiltration?

In the first picture, what is going on in that gap? [rot, bugs etc] Reason I ask is that I honestly have no idea, I've only lived in stand alone SFHs, condos and high-rises where this is not an issue.

It's two SFHs built so close together than you can't access those exterior walls, but with a small gap so you can still get issues with rot, bugs, etc.

How? This is mesmerizing to me. Again, I'm totally ignorant here.
E] Wouldn't' it be better to just build like the second picture?
The thing I wonder about is how the heck do they do any maintenance? With there being a gap between there, how do they protect against water damage and subsequent mold?
I also wonder about what happens if wildlife or pets get stuck between there.
Also, that sort of situation would be a freaking disaster here. We have a big tree canopy here of Live Oaks that drop their leaves in the spring, and holy hell, do they drop their leaves. You'd have a vertical compost happening there up the roof in less than a decade. The crazy thing is, Houston being Houston, not only do they have pine trees and palm trees, but they also have some giant Live Oaks in their central neighborhoods. Not to mention that even in the absence of a tree on one's lot, Houston is a rather windy city, especially during storms that would blow leaves into that space. And then there's the flooding issue that Houston deals with pretty much every year.

Yes these are exactly my questions.

That's what I was thinking, hell how do they even put siding on it if it's not brick? How is it even sealed?

Typically this isn’t allowed per the IBC (not sure what they use in Texas) without a parapet between. What it tells me is that the entire roof assembly is likely 2 hour fire rated including wrapping the members. That’s what keeps the fire from spreading from one unit to the next. Aside from that, I echo the WTF comments on maintenance and upkeep. In California you would at least cover that with a seismic joint.

i've never seen frame construction zero lot line homes in chicago. when we do have zero lot line homes directly next to each other, they're always brick and built right next to each other (no absurd 8" gap like that houston example).
when there is a gap in chicago (and gaps are common), it's typically 3' or so to serve as a gangway from the front to the back of the property, a fire code regulation that harkens back to the days of the great fire.

theres like 1’ gaps or less between some houses in st louis in areas where the rowhouse areas messily transition to 3’ gangways...i presume that they pointed the mortar joints over the wall as it was built from the inside...

ive definitely seen some buildings with gaps of this size on occasion in the city. it seems to me they accumulate a lot of trash and theres really no way to access the slit if there is an issue with maintenance (or just like, wanting to clean up a couple decades worth of garbage).
