Admittedly you don't expect to see one in a random suburb.
There's a story, not sure how true it is, of a contractor being brought in to renovate a recently-vacated government office building of something like 7 storeys. They came back and said "OK, we've looked at the 7 storeys above ground, what about the three below ground?" / "What 3 storeys below ground? There aren't any below ground".
Even then, it might be far cheaper to build an "EMP resistant" structure aboveground.
