A blanket permit is an expedited construction permit for certain office tenant improvement projects. Once you set up your blanket permit, the application, review, and issuance process for future work is streamlined. Blanket permits are intended for building owners or operators who will need multiple permits over time for work in large (50,000 square feet minimum) office buildings.
Office tenant improvement projects may also qualify for a subject-to-field-inspection permit.
You may also need a business license if you are working in Seattle, even if your office is outside the city.
When you set up your blanket permit, you will need to deposit money into an escrow account for payment of future blanket permit fees. Fees are based on either the square footage or value of your project, but are typically less than standard construction permit fees.
Setting up your blanket permit will take about a week once you submit the necessary information. We try to review each subsequent submittal related to the blanket permit in about 2 weeks.

Contact us. Call or email a resource and production co-manager to confirm that your project will qualify for a blanket permit and to obtain a project number.
Set up a notebook for your project. The notebook should be an 8-1/2 x 11 inches three-ring binder with the following items included:
Submit your notebook. Drop off the completed notebook at the reception desk on the 21st floor of the Seattle Municipal Tower.
Pay fees. Once your notebook has been reviewed and an application created, you will be asked to pay a setup fee and deposit money into an escrow account for payment of future blanket permit fees. We will keep and maintain your blanket permit notebook.
Prepare your plans. Plans should be to scale, easy to read and microfilm, and should show the proposed construction work. A typical set of plans will include a coversheet, location plan, key plan, floor plan, construction details (including relevant details from your blanket permit notebook), and architectural notes.
Submit your plans. Submit your documents at Plans Routing on the 20th floor of the Seattle Municipal Tower. You do not need an appointment. Include the following with your submittal:
Make corrections and resubmit your plans. Your project reviewer will send you a corrections letter if changes are needed.
Pay fees. The required fee will be subtracted from your blanket permit escrow account. If the fee exceeds the balance of the account, you will need to submit an additional amount to cover the difference, plus enough to cover future work under the permit.
Pick up your permit. You will be contacted when your plans are approved. You can pick up your permit and approved plans at the permit issuance counter in the Applicant Services Center.
