Tiny House Regulations California

California Information Bulletin on Tiny Houses/Cabins:

California Tiny House Legality Update –  ( For Further Information Contact Dan Fitzpatrick with American Tiny House Association)  Effective Date  January 1, 2020

California Building Code Update – Appendix Q Tiny Houses: In recent discussions and emails with key staff of CA Department of Housing and Community Development (HCD), we have confirmed the following: 
1) HCD has adopted the provisions of Appendix Q which will make its provisions MANDATORY across all local government jurisdictions.
2) We were able to confirm with HCD, that factory-built housing (FBH) next year can be built to CA Residential Code standards, inclusive of Appendix Q, (for units 400 sq. ft. or less).
3) Such FBH units built using Appendix Q standards would be permitted anywhere is California, subject of course to zoning codes.
4) The California building code update will go into effect January 1, 2020.

BACKGROUND: For the past several months we have been quietly working with California Department of Housing and Community Development (HCD) and the Governor’s Office of Planning and Research (OPR) to ensure that provisions of the 2018 International Residential Code, including our tiny house Appendix Q code provisions, were properly implemented into the California Residential Code. Our concern was that we wanted Appendix Q code items for tiny homes to be, not only adopted by the state, but made MANDATORY in all of the 540 local government jurisdictions. In past California code update cycles, the various Appendices were left as local option.

Why is this important? One can only imagine the effort it would take to convince 540 cities and counties to adopt Appendix Q – a task which would take years to accomplish. Also, if Appendix Q provisions were not adopted across the board for all of California, it would be virtually impossible to factory build tiny house units for wide distribution.

 

Special Thanks to the American Tiny House Association for providing this list. These are the most recent updates for the State of California and those jurisdictions Allowing. This list is comprehensive.

Tiny House Friendly: 710

  • Tiny house regulations and codes may vary by city, town, or county.
  • Most cities in California allow tiny houses as accessory dwelling units (ADUs).
  • Fresno is the first city in the country to approve tiny houses on wheels as secondary dwelling units in residential neighborhoods.
  • San Francisco is another city that now allows secondary dwelling units.
  • California Title 25 does not allow the use of a recreational vehicle to be used as a
  • dwelling unit.
  • In response to the Sonoma County wildfires, local ordinances allowed persons displaced by the fire to live in RVs or tiny houses outside the burn zones temporarily and without permits.

A tiny house friendly state, California is also one of the most popular states for nomads living in their vehicles–despite not being legal. The California Health and Safety Code defines a Recreational vehicle as a motor home, travel trailer, truck camper, or camping trailer, with or without motive power, designed for human habitation for recreational purposes. Legal or not, California continues to be popular for people who live in their camper vans. Specifics may vary by city and county, but as a whole, California appears to support living in a tiny house.
