San Juan County has adopted the state building codes and has adopted some amendments to them. This list of Design Criteria will help professionals correctly determine how to design structures built in our our area.
International Residential Code as amended by the state: IRC
International Building Code: IBC
WA state Building code council: SBCC.wa.gov
SJCC: San Juan County codes
First thing to do is to check and see if the proposed work actually needs a permit. SJC has a list of items that are exempt from permitting. Additionally we offer some insight for pre-application assistance.
If your project does require a permit, you can find permit applications here Permit Applications.
If you are ready to apply for your permit, please create an account and check out our Permit Portal
1. Standard Residential Building permit: Most common permit type for Single Family Residence (SFR) built using the International Residential Building Code (IRC). This will cover a 1 or 2 family residence or accessory structure 35’ in height *(max) and 3 stories tall. Standard building and energy codes apply.
2. Commercial Building permit: This permit involves new construction AND changes in occupancy from one class to another for commercial uses like: Offices, Mercantile, Assembly, Retail, Storage, or Hazardous occupancy. ALL occupancy classes will be governed by the International BUILDING Code (IBC) and WA state commercial energy code.
3. Remodel/Addition permit: Same as above, just smaller in scope. May have the same application and permit document requirements depending on size of project.
4. Plumbing/Mechanical permit, or Single trade: Single trades like adding a LPG tank and heater, or new furnace or water heater. Typically only involves the Plumbing or Mechanical aspect of the codes. If you are adding square footage, or remodeling a house, use standard building permit (Residential or Commercial)
5. Demo Permit: Removes a structure completely. Demo permits are required to remove the structure from the tax assessor’s inventory. Moved structures require Demo permits.
6. Moved structure permit: Used when moving an existing approved building to a new location, even when on the same lot. Permission to move on County roads is required. Moved structure will require permitting and approval PRIOR to placing at new location.
7. Revision: Permit to revise or change scope of work from approved plans. Revisions are required when; adding new sq/ft, or height of building, siting the building at a different location on the same lot, changing number of bedrooms or egress, adding fixtures not previous approved, and changing the construction of the building which requires new plan review (like changing roof type, or revised engineering).
8. Owner Builder: (standard-Occupied structure) and OB Exempt(non-occupied structure): San Juan County is unique in that we offer a different permit type in which the owner can build their own building and it is exempt from the structural parts of the IRC. 15.04.540 governs the construction of Owner built structures in San Juan County. There are some restrictions, please refer to the county code for details.

SJC and the state of Washington have adopted an energy code that has increased requirements over time to combat climate change. It requires that new buildings and remodel work meet ever increasing standards for efficiency and energy savings. The 2018 version of this code has increased the requirements of the number of credits required to get approval of a single family dwelling in our state. In fact ALL Residential construction is subject to the energy code requirements and credits.
Depending on the size and scope of your project, you may be required to attain additional credits by using energy efficient equipment, or adding insulation, or adding other energy saving methods during construction. The form for the 2018 energy code and its worksheets can be found online at : Energy code WA state. The site has in depth information and training options available, please make time to review this information prior to submitting applications, or questioning staff.
The forms are also available on our permit application webpage
