What type of permit / approval do I need?
The permit required depends on your development intent. You may need several permits for 1 type of development activity. The list of Engineering development permits is online.


Other federal, state and local permits may be needed. Check with the local jurisdictions/districts for water and sanitary sewer hookup information. A good resource for checking what federal or state permits you may need for your development is a handbook titled “Commonly Required Environmental Permits for Washington State.”
