Grading is the process of excavating or placing soil on your property.
You may need a grading permit if your project includes any of these activities:
If your grading project is part of a construction permit application, you do not need a separate grading permit.
For a complete list of work that needs a grading permit, and for possible exemptions, see Seattle Municipal Code (SMC) 22.170.060. In general, you will need a grading permit if your project will include any of the following:
You will need a grading permit for work in a shoreline district (the land within 200 feet of the ordinary high water mark of most lakes and bays and the Puget Sound) if:
You will need a grading permit for work In Environmentally Critical Areas and Buffers if you are disturbing land in:
In addition, in environmentally critical areas and buffers, you need a grading permit and possibly an environmental review if:
Whether you need a permit or not, you need to meet all code requirements such as restrictions on land disturbance in ECAs and their buffers.
The fee for review a grading permit is based on the time it takes us to complete the review. Our review fee is based on the Seattle DCI hourly rate.
How long it takes us to review your grading permit application depends on the complexity of your project. Depending on the scope of your project, we may take 2 days, 2 weeks, or 8 weeks for the initial review. Each additional review cycle takes at least 2 weeks.
Get your property information. Find property information to help you plan your project.
Determine restrictions to your project. Research the codes to determine requirements and limits for your project.
Determine if you need an environmental review. You might need an environmental (SEPA) review in addition to a grading permit. We need several months to do a SEPA review, which must be submitted before you apply for a grading permit.
Attend a coaching session. We offer 20 minutes of free coaching to answer drainage, land use, geotechnical or construction permit questions. If you need a longer coaching session, we offer one-hour sessions for a fee.
Start your application. Complete the Building & Land Use Pre-Application online using the Seattle Services Portal. You will need to upload a site plan and a complete legal description for your site.
Request a pre-application site visit. You need a pre-application site visit if you will disturb more than 750 square feet of land or disturb any land on a site with an environmentally critical area (other than liquefaction or peat-settlement prone areas). Request a pre-application site visit online through your Seattle Services Portal. You'll receive an email once we have added the pre-application site visit (PASV) fees to your project. After you have paid the fee, we will perform the inspection. Our report will include information from the utilities about your specific site and proposal. Our report will also identify potential project stoppers.
Request a pre-submittal conference (optional). We recommend pre-submittal conferences for very complex projects, including buildings with unusual structural systems, substantial alterations, or work in environmentally critical areas or shorelines. One-hour pre-submittal conference fees vary based on the type of conference you need.
Apply for exemptions. You may need an exemption from code requirements if your project is located in an environmentally critical area or near the shoreline.
Prepare your plans. Plans should be to scale and easy to read.
Fill out and upload forms.
Coordinate with other agencies. You may need permits or approvals from other agencies. These are the most common agencies you may need to work with for your permit type:
Get your project screened. We screen your application to make sure it is ready to submit. Screening is available through your Seattle Services Portal. You may schedule an appointment without screening if you are a consistently prepared applicant with a rating of 80 percent or better.
Schedule an intake appointment. Schedule an electronic intake appointment through your Seattle Services Portal.
Submit Your Permit Application. Submit electronic permit application materials through your Seattle Services Portal before 7:00 a.m. the day of your appointment. You do not need to come to SDCI for the intake appointment. If you submit all your application materials before your scheduled intake day, your application may be screened and processed earlier.
Pay fees. You will pay an initial fee for one hour of review. Fees are due on the day of your intake appointment and must be paid within 48 hours or your intake may be rejected. We will add other reviews (e.g. geotechnical review) depending on the scope of your project. All reviews will be at our hourly rate.
Make corrections and resubmit your plans. After your permit application, we review your plans. Once all of our reviews are done, you will receive an email telling you that corrected and/or additional documents can be uploaded into your portal. Your project may require multiple correction rounds before our reviews are complete
Pay final fees. We will notify you if you need to pay any final fees before we issue your permit.
Print your permit. We will notify you when we have issued your permit and the documents are available in your Seattle Services Portal. Print the permit and approved plan set and have it on site for our inspector.
Display your permit. Place your permit in a visible location on the project site.
Get related permits. You may need to get additional permits or approvals from other departments.
Request an inspection. See the construction inspections page for when to call us and how to schedule your inspection.
Get special inspections. If we assigned special inspections as part of your grading permit, some parts of your project will need to be inspected during construction. See the special inspections page for more details.
Close out Special Inspections for your project. See the special inspections page for information on how to submit a final letter to us for review.
Close your permit. Your permit information will be archived in our electronic document management system.
