“Unconfirmed” means the city's code doesn't state the rule plainly enough to publish. Those city pages link straight to the ordinance section instead.
Why neighboring cities disagree
Every city starts from a model code and then edits it. One town raises the shed cutoff, the next lowers the fence height, a third exempts the structure where its neighbor only exempts repairs to it. None of that is visible from a national article — you have to read each ordinance, which is what these pages do.
