Except where a home occupation is involved, no structure originally designed as a residence (including hotels and motels), or as an accessory structure or addition to a residence, shall be used for any commercial or office use, unless the building and site are improved to meet all code requirements for an office or commercial development. This includes, but is not limited to, building codes, fire codes and the requirements of this title. Such a conversion may be a permitted use or may be subject to a conditional use permit process, depending on the base district use regulations. (Ord. 805-14, 7-1-2014)
