Health Code Update

We're Updating the Board of Health Code, and we want to hear from you

The Snohomish County Health Department is working on a multi-year effort to modernize its Health Code. From septic systems to food safety, we’re making sure that these local rules reflect today’s needs, best available science, and community values. Stay updated on the latest developments by signing up for email updates.

  1. Connecting to public sewer
  2. Fee adjustment
  3. Property transfer inspections
  4. Septic contractor reporting

Description 

Washington State rules for septic systems outline several cases where connection to a public sewer system may be required versus installing a septic system. There are currently no local rules that explain how the mechanics of this state rule operate in Snohomish County. This rule only concerns new construction and is intended to be applied in extremely narrow circumstances. The draft code language (linked below) would make changes to Chapter 5.05 of the Board of Health Code.
