Full Breakdown
The 2022 Zoning Ordinance (Subtitle 27) does not define or separately permit 'tiny homes.' A tiny house on a permanent foundation is treated as a single-family detached dwelling and must meet that zone's minimum lot size, setbacks, and building code. A tiny house on wheels is generally an RV or travel trailer, which cannot be used as a residence except under the narrow 'Transient Manufactured Home or Recreational Vehicle Residence' temporary use (Sec. 27-5303). That use requires a lot of at least five acres, an amusement-tax principal activity, and a Temporary Use Permit valid no more than 120 cumulative days per year.
Violations & Fines
Living full-time in an RV, travel trailer, or tiny house on wheels on a residential lot, or placing a tiny home as a second dwelling, can trigger zoning enforcement, fines, and orders to remove the unit or cease occupancy.
