Building a tiny home as a residence is the same as a “regular” home (see brochure). The home needs to be sited outside any critical area buffers like streams and geohazardous areas (like landslide-prone areas). You would also need to hook it up to a septic system and have potable water. Check with Environmental Health on septic and water requirements at (360) 385-9444. If you have questions about the construction of the home, contact our Building Plans Examiner at (360) 379-4461.

Canvas yurts can be permitted as a temporary living structure, such as seasonal camping, but may not contain a heating element or plumbing and have size restrictions. In order for a yurt to meet code and be allowed, it must be less than 500 sq feet, unheated and unplumbed and only used for temporary use, such as camping. Yurts, built using a standard canvas exterior over a wooden frame, are not able to meet energy code for heat retention and do not meet the requirements for fire, life and safety and therefore are not permissible as a residence. With these guidelines, a yurt can be permitted along with the platform or decking it will be built upon.
Hard-sided yurts are permitted so long as they meet energy code. Pre-engineered kits are available from online resources.
