Pool permit process

The Snohomish Health District reviews plans for new, altered, and remodeled spas, pools, and other public water contact features. Existing water recreation facilities must apply for an annual permit and are inspected two to three times each year. For annual permit costs, see our Living Environment fee schedule.

All public water recreation facilities must be constructed and operated in accordance with Washington State law, including:

  • Swimming pools
  • Spray pools
  • Spa pools
  • Wading pools
  • Water contact fountains
  • Water slides

Permitting a new water recreation facility

To successfully complete the permit process for a new public water recreation facility in Snohomish County, you must submit each of the items on the following checklist to the Snohomish Health District. 

After the construction report is submitted, a pre-operation inspection will be provided by the Snohomish Health District. At this point in the process, your facility must be in full compliance. A re-inspection fee will be charged if an inspector has to return to the site.
