The only real "correct" way to do it outside of zoning approval is for <91 days per year (and keep records) or for <180 days per year (and keep records) if you are running it as the primary resident.Categories of Limited Lodging.Two categories of limited lodging are recognized, and both shall comply with the standards provided in § 14-604(13)(c) (Standards).
