Side Sewer Contractor & Certified Individual Registration

What Is It?

You need to be a Registered Side Sewer Contractor (RSSC) to repair or construct a side sewer in the public right-of-way. You also need to be a Registered Side Sewer Contractor to perform pavement restoration (this replaces the Registered Pavement Restoration Contractor previously issued by the Seattle Department of Transportation). You do not need to become an RSSC if you are only working on private property.

When you become an RSSC, remember that:

  • You must renew your license each year
  • You can check your status and view a full list of current RSSCs
  • The exam costs $100
  • The registration fee is $200
  • The annual renewal fee is $150

Annual Registration Renewal
Your registration expires on December 31st of each year and must be renewed (see the bottom of this page).

To renew, you must submit a completed registration renewal form, and include:

  • A copy of your current City of Seattle business license
  • The renewal fee of $150

If you don’t renew your registration within one year after it expires, you must provide proof that you met the initial registration requirements to become an RSSC.

Annual Renewal

You need to renew your Registered Side Sewer Contractor license annually, per per Seattle Municipal Code (SMC) Chapter 21.16.060. You must renew your license through the Seattle Services Portal. You must upload a new RSSC Agreement/Renewal form and renewed City Business License with your renewal request via the Seattle Services Portal. We will email renewal reminders each November.

If you do not see the renew option in your portal account, under My Records in the Licenses - Trade and Equipment section, it may be because the contact listed on the license is not the same as the contact that is linked to your portal account. We can correct this for you by merging the two contacts. To do this, send an email to with the email subject title "RSSC Renewal Trouble/Contact Merge for LIC-SS-xxxxx." Be sure to include the license number so we can quickly reference the correct RSSC record.

Additional Renewal Information

  • The required renewal forms (RSSC Agreement/Renewal Form and a copy of next year's City Business License (not the receipt)) must be uploaded under your renewal request when you select the renew option. This will help avoid delays in processing your request.
  • Your RSSC license expires on 12/31 annually.
  • You will not see the renewal fee until after you select the renew option in your portal account. We do not start the renewal process and our review of the RSSC Agreement form and the renewed City Business License until you've initiated the renewal process through the Seattle Services Portal.
