The city’s development code defines and regulates chassis-mounted tiny houses as a distinct type of dwelling. Its definition for “tiny house” stipulates six conditions: licensing and registration with the state department of motor vehicles, the ability to be towed, compatibility with size limits for vehicles, minimum first-floor living space, self-containment as a functional dwelling unit, and design  (§15-6802). Tiny houses are permitted as a type of accessory dwelling unit, subject to standards addressing design, minimum lot size, units per lot, unit size, lot coverage, setbacks, entrances, space between buildings, unit height, openings, access, parking, mechanical equipment, utility meters/addressing, home occupations, airport compatibility, and owner occupancy (§15-2754).

Zoning Reform and Code Writing

The city adopted a new unified development code in 2015 (Chapter 15). It includes a mix of use-based and form-based zoning standards. It defines and regulates uses based on broad categories, with select specific use types, and includes use-specific standards to minimize reliance on discretionary use permits. It is richly illustrated and uses tables to organize use permissions and dimensional standards.

Its purpose statements address guiding physical development to implement the local comprehensive plan; fostering harmonious land uses and compatible infill development; supporting economic development and job creation; providing for the housing needs of all economic segments of the community; promoting high quality architecture and sustainable design; protecting existing land uses; promoting a safe and efficient multi-modal transportation system; facilitating the appropriate location of community facilities, institutions, parks, and recreational areas; protecting and enhancing property values; protecting and enhancing the appearance of the city; and defining duties and powers of governing bodies and officials (§15-102).
