Building Division Frequently Asked Questions
The WA State Residential Code exempts small accessory structures, such as tool sheds and playhouses that are 288 square feet or less and limited to one-story. The accessory structure would still have to comply with the required zoning setbacks.
Small dwelling units less than 1500 square feet require 3 energy credits, medium size dwelling units require 6 energy credits, and large dwelling units exceeding 5000 square feet require 7 energy credits.
There are 7 categories to choose from and you can only choose one option from each category.
You can call the county and we can calculate your snow load for you but you will need your parcel number when you call.
The county will always provide you with the ground snow load and that will be accurately converted to the roof snow load by your design professional or truss manufacturer.
Yes, a permit is required from the county and the manufactured or mobile home must be a certified HUD home or approved by WA State Department of Labor and Industries. The county issues the permit for the foundation system/setup only.
True Park Model RV’s are certified to the ANSI A119.5 Standard and are regulated by WA State Department of Labor & Industries as Factory-Assembled Structures. They can be used as permanent dwellings as long as the unit contains a WA State Insignia approved by State L&I and the unit is placed on a permanent foundation with approved utilities.
Yes, Yurts are allowed to be used as permanent dwelling units as long as the structure is placed on a permanent foundation, is not used for camping or recreational uses, and meets the current building code requirements for structural, life-safety, and energy efficiency.
Yes, Tiny Houses are regulated by the WA State Residential Code, Appendix Q and are allowed to be built onsite as permanent dwellings. Tiny Houses on wheels that are constructed offsite must be approved by WA State L&I as Factory-Assembled Structures.
A fence can be used as the barrier requirement and the gate access must also be controlled. In lieu of a fence, an automatic pool cover complying with ASTM F1346 may be installed. If the dwelling is used as part of the pool barrier then there are requirements for doors and windows that access the pool area as well.
No, per RCW 18.08.410, a residential building up to and including four dwelling units is exempt from having to have the structure professionally designed. However, elements of the structure that exceed the prescriptive requirements of the code may require engineered design, such as where ground snow loads exceed 70 pounds per square feet.
No, these structures are not regulated by the WA State Residential Code so no “building” permit is required. However, there is a siting permit required to verify setbacks from critical areas, and property lines.
A structure that required a building permit and was constructed without the proper permit was illegally constructed. Obtaining the permit after the structure has been completed does not deem the structure to be legal in the eyes of the code.
Permit applications are valid for 6 months and the application period can be extended an additional 6 months as long as the customer pursues their permit in good faith. If not pursued in good faith, the application expires and is cancelled. Once the permit has been issued it is valid for 2-years to complete the required work.
No. Accessory structures regulated by the WA State Residential Code are garages, carports, shops, and similar structures and cannot contain habitable or living space elements or they would be deemed dwelling units. Accessory structures can contain a bathroom since this element is not considered habitable space by the building code.
