It depends. Most shacks built in one's backyard do not pass any building codes. Or throwing a wooden plank over a stream somewhere. Just like most software doesn't really risk anyone's life: the fact that your web site might go down for a bit is not at all like a bridge collapsing. Companies do care about long term maintenance costs, and I've mostly been at companies really stressing over some quality metrics (1-2 code reviews per change, obligatory test coverage for any new code, small, iterative changes, CI & CD...), but admittedly, they have all been software shops (IOW, management understood software too).
