Street Improvement Permits

Please Note:

Changes to the Street Use permitting fee schedule will be going into effect on April 1, 2018. With approval from City Council as part of the 2018 budget, we are implementing changes to our permitting fee schedule to more accurately reflect the true costs of project permitting. Click here to read our fact sheet. 

For construction permits,
the permit issuance and renewal fee changes will be as follows:

  • Simple: $146 to $150
  • Complex: $305 to $313
  • Street Improvement Permits/Utility Major Permits: $146 to $4700
  • Permit modification and extension: $155 to $159

For short-term public space permits, the permit issuance fee is increasing from $146 to $175.

For long-term public space permits, the issuance fee is increasing from $146 to $224, while the annual renewal fee is increasing from $140 to $170.

Costs will be decreasing for permits for public amenities, such as street furniture and artwork. While the issuance fee for public amenities is increasing from $146 to $224 for the first year of issuance, permit holders will be allowed to renew their permits for free every year thereafter, as long as renewal is approved.

Lastly, the general rate for permit review and site inspections is increasing from $209/hour to $260/hour.

If you have questions concerning these changes, please contact or call (206) 684-5253. For questions related to Public Space permits, please contact or call (206) 684-5267.

Due to a high volume of permit applications and significant staff transitions, we are currently experiencing longer permit counter wait times and permit application review timelines. Please plan your trip to the permit counter and project timelines accordingly.

Permit Counter Wait Times (may vary with number of visitors)
           Construction use: 40-60 minutes
           Minor utility: 20-40 minutes

Permit Review Timelines (may vary with permit complexity)
           Arterial streets / construction hubs: 8-10 weeks
           Non-arterial streets:  6-8 weeks
           Modification requests: 4-6 weeks

(Note: Individual status inquiries may not be responded to if the permit review time has not exceeded the timelines listed above.)

When are Street Improvement Permits (SIPs) required?

A newly restored sidewalk along a street.The Street Improvement Permitting group builds on reviews done by our Development Review Program. There are two instances in which street-improvement permit are required:

  • Title 23 of Seattle Municipal Code dictates that certain types and sizes of development projects require that additional improvements be made to the right of way. These may involve direct improvements to the street, sidewalk, and/or planting strip, or installation of public utilities to serve the area.
  • Others choosing to voluntarily install street improvements will also need to obtain a SIP prior to improving the public right of way

When Title 23 requirements are triggered, required street improvements may include, but are not limited to, installations such as new street pavement panels, new sidewalks, or plantings.
