Permit Requirements for Everson, Washington

For Plumbing projects in Everson, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Whatcom County.

Whatcom County Plumbing Permit Requirements

Whatcom County's Planning and Development Services (PDS) Division handles building and safety matters, including plumbing permits, for properties in unincorporated areas. If your property is located within an incorporated city, that city's building department is responsible for permits, not the county.

For plumbing work, you will generally need a Plumbing Permit or a Mechanical Permit. These are typically stand-alone permits. For non-commercial projects, they usually do not require a Master Application, Land Use permit, or detailed site/building plans.

Applying for Permits

Applications and requests for permits should be submitted electronically. You can use the county's online Customer Service Portal or email the completed application forms as PDFs to [email protected].

For replacement fixtures, you can apply through the online portal. For newly installed fixtures, you will need to complete the appropriate form from the Applications page and submit it electronically.

If you are unsure about the type of application needed for your project, you can contact the Building Services Division at 360-778-5900 or [email protected].

Permit Fees

Plumbing permit fees are based on the type of fixture or work being done. A fee schedule is available, which includes fees for items such as bathtubs, water heaters, and various types of sinks and drains. A 3% technology fee is applied to all permit and application fees.

Inspections

All permitted work is subject to inspections by county staff. Residential projects require inspections as work progresses to ensure compliance with applicable codes.

For inspections, you can schedule them online through the Customer Service Portal. Approved plans, the permit, and an inspection record must be on-site during the inspection.
