Park model tiny homes in Humboldt County, California

What Humboldt County allows

Humboldt County was the second county in California, and the state's first rural county, to permit a movable tiny home as a habitable accessory dwelling unit. The county draws a clear line between a Moveable Tiny House (MTH), a certified, code-compliant category built for long-term housing, and an ordinary recreational vehicle, which remains restricted to manufactured home parks, special occupancy parks, and public camping areas. Once installed to the county's MTH standards, the unit carries the same legal status and protections as a conventional dwelling, while still retaining the option to be relocated or sold independently.

• Installed on a property with an existing single-family home, as an accessory dwelling unit
• Certified to NFPA 1192 or ANSI A119.5 (Park Model) standards and licensed with the California DMV
• 400 square feet or less
• Skirting conceals the undercarriage, wheels, axles, tongue and hitch
• Exterior materials must be non-reflective (no more than 10 percent reflective surface), with double-pane windows and a minimum 1:12 roof pitch
• Wildland Urban Interface (WUI) building requirements apply if the parcel sits in a designated fire hazard area
