Full Breakdown
A stick-built tiny home faces no special zone restriction beyond the base residential district's own standards; it is permitted in any residential zone. A tiny home built on a trailer with wheels is treated differently: it may serve as the main house only in the RH, GR-1, SR, and MH zones, and only once it is attached to a foundation and either ground set or skirted so it no longer functions as a towable trailer. Outside those conditions, a wheeled tiny home is permitted by right as a dwelling only in the MH (manufactured home) zone.
The code separately allows a tiny home, on a foundation and ground set or skirted, to serve as an accessory dwelling unit rather than the main house: in the RH and GR-1 zones that ADU use is allowed outright, while in the SR, R-1, and R-2 zones the same tiny-home ADU needs an approved Type I conditional use permit and must be sited behind the main house behind an opaque wall or approved alternative screening.
Violations & Fines
Placing a wheeled tiny home as a main house outside the permitted zones, or without the foundation and skirting requirement, is a civil infraction under Town Code Section 18.95.030, enforced through zoning administrator inspection, written notice, and citation. Section 18.95.040 sets the penalty at up to $750 per day for an individual or $10,000 for a corporation, with each day a separate offense before the town magistrate.
