The city’s municipal code defines and regulates chassis-mounted tiny houses as a distinct type of dwelling. Its definition for “tiny home on wheels” stipulates a minimum first-floor living area of 140 ft2 (§17.10.030). Tiny homes on wheels are permitted as accessory dwelling units, subject to standards addressing permissible locations, units per lot, licensing and registration with the state department of motor vehicles, compliance with ANSI 119.2 or 119.5 (NFPA 1192) requirements, the ability to be towed, the inability to move on its own power, compatibility with size limits for vehicles, skirting, unit size, and design (§17.70.080).
