That, and almost anything else!  A friend of mine bought a new house in a shitty area; a really nice house in a shitty area, so he set right to work fixing it all up. Almost immediately, a city inspector showed up to tell him that he did not have a permit for the carport and garage office that it CAME WITH! I was between jobs at that point, so he hired me to help demolish these things, and it was such a shame; the previous owner had built them really well.
