Many municipalities adopt restrictive housing codes. For instance, you cannot build a house less than X square feet in size. You must have a lot size of X square feet (or this may be expressed in acres). The international residential building code, which has some good things in it, but may be overkill for a smaller structure (like the ones mentioned, which are 320sf or less), must be followed. These sorts of thing force compliance on 2000sf, multi-story dwellings with all kinds of complex systems; but is it needed for a well built but small, glorified storage shed? I would argue, "no".
