The Building Division of Development Services reviews applications for structures within the unincorporated areas of Grant County.  If your property is within city limits for any city or town, you will need to contact the appropriate city or town building department to discuss their requirements.  

Electrical permits are done by the Washington State Department of Labor and Industry.

How long are permits good for?

What permits are REQUIRED or EXEMPT?  

Permit Inspections
Inspections are scheduled during office hours, M-F 8 am - 5 pm., by calling our office at 509-754-2011 EXT 3001 or directly by visiting our lobby.  Inspections are generally scheduled for the next business day. Due to heavy inspection load, times cannot be requested or provided; you should allow the entire next business day for the inspection to be conducted and schedule your job accordingly.  

 Special Notes   Requirements for applying, permitting, construction, and inspections are subject to change at any time based on local, state, and federal law or policy, building code cycles, and such. What was required or allowed in previous years may now be different. With variables involved in the many different project types including differences in codes, fees, plan requirements, and departmental approval requirements, we are restricted in the amount of information we can provide in this forum that would pertain to each possible project.

For any land use questions or concerns, such as addressing, zoning, setbacks, shorelines, SEPA, wetlands, 2nd home, accessory building before residence, etc., please contact the Grant County Planning Division at 509-754-2011 ext. 2501.

All submittals for permits require Complete Application Packets.  Incomplete packets will not be accepted.  The more complete the information you are providing the faster the plan review process will be.

A few more details to be aware of…


Once we have received your portal submittal, we will review the documents and plans for completeness.  If the submittal is NOT complete, we will contact you to provide the deficient information within a set deadline.  If the information is not received by the provided deadline, we will cancel the submittal and refund any deposit paid.

If the submittal is complete, the submittal will be routed to all departments for plan review.   After the departments have signed off on the plan review, we will notify you by email your permit application package is approved and ready for issuance. The email will provide you with instructions on how to pay and print the approved on-site permit package.  You are responsible to print all approved documents and plans in color and have available to the inspector at the project site.  Many of these documents will need to be printed 24" x 36" in size.
