Tiny House Regulations Alaska

Alaska

  • Tiny house regulations and codes may vary by city, town, or county.
  • Anchorage:
    • Tiny houses on wheels are treated as RVs and restricted to R-5 zones.
    • Tiny houses on foundations or manufactured homes, face fewer location restrictions. They will require a conditional use permit and building codes will need to be met.
    • Tiny homes on municipal property must be connected to water and sewage.
    • Interest in tiny houses appear strong state-wide, however, there are currently few tiny houses in the state at the present time. At the moment, tiny houses aren’t “officially” allowed in the city of Anchorage, but with a conditional use permit it may be possible. Areas around the cities are slightly more flexible, but no specific tiny house building codes exist yet

March 10, 2020   City and Borough of Sitka, Alaska Approves Tiny Houses for Dwellings:

The City and Borough of Sitka, Alaska creates history for the tiny home industry. The second and final reading for ORD 20-02S (A)  passed at a vote 6 to 0 and is a great win for movable tiny homes. Sitka, Alaska has approved tiny homes on a foundation, but what is groundbreaking, is they have written an ordinance that amends Appendix Q that applies to movable tiny homes. From the floor joists up, the tiny home will be built to the IRC Appendix Q.

The chassis on which a tiny house is placed or constructed, including all components attached to the chassis, shall be of adequate structural strength to resist all dead and live loads imposed upon it and/or required by applicable safety standards. The Building Official may require third party certification to ascertain compliance with this section.

Legal Classification: Tiny House On A Chassis

It is somewhat of a hybrid standard, built to local building codes, though Sitka created their own classification which allows for full time living with conditions. The trailer will need to be registered at the DMV for transport purposes and the trailer should be structurally rated to support the load which is placed upon it.

Various other deferred jurisdictions may have a different view on whether they allow or accept the concept as meeting the intent, if not the letter, of the adopted codes. You would need to contact those jurisdictions directly.

Outside of the deferred jurisdictions, the State of Alaska does not regulate detached single- and two-family dwellings. If the tiny house is being used for an application where you have more than two non-separated dwelling units (e.g. IBC Group R-2), then you’ll need to work with the State.
