Because Bostonia is unincorporated, tiny-home rules come from the County. A tiny house built to residential building code on a foundation can qualify as an ADU (permitted up to state-mandated sizes with 4-foot setbacks) or a single-family dwelling. A 'tiny house on wheels' is classified as a recreational vehicle or trailer coach; the County restricts using RVs/trailers as permanent dwellings on private lots outside of licensed RV parks or approved temporary situations. Movable Tiny Houses may be allowed as an ADU only where the County ordinance and state law expressly permit them, subject to certification and hookups.
Living in an uncertified tiny home or RV as a permanent residence outside approved zones is a violation the County can abate through code enforcement.
