Scheduling a land use inspection

Land use inspections

  • Permit issuance and plan approval notification

    Permitting applicants are notified when their site development plans or permit(s) are approved for construction. The notification includes information about any outstanding fees, financial guarantees, and requirements to set up a preconstruction conference.

    For smaller projects that involve work in the road right-of-way and do not require site development plans, contact Permitting Inspections at 206-296-6600 after preliminary approval or permit issuance to schedule the preconstruction conference.

  • Preconstruction conference

    A preconstruction conference is required prior to any land clearing or grading on any site requiring a permit approval. Land use permit types that involve construction activities typically includes subdivisions, short subdivisions, clearing, grading, and right-of-way use permits. Land use inspections also are required for some commercial and large residential permits.

    Request a preconstruction conference by calling Permitting Department Inspections at 206-296-6600, and please allow lead time, up to three working days for the conference to be scheduled. A land use inspector will be assigned to your project.

  • Notice board requirements

    A Notice of Construction Activity Sign board must be posted on a site when construction is related to a subdivision, commercial building permit, or grading permit that is subject to SEPA. This sign must be posted prior to any construction and must be in place as authorized by Permitting or until the project construction is approved.

  • Erosion control supervisor sign

    This sign shall identify the Erosion Control supervisor and phone number in accordance with the Surface Water Design Manual.

  • Scheduled inspections

    The King County Road Design and Construction Standards specify certain events that require monitoring and inspection by Permitting Inspections. In addition, the King County Code, Surface Water Management, Title 9.04, and the related Retention/Detention Facilities, "In Operation" Public Rule, requires certain drainage related inspections before improvements and/or buildings are constructed or subdivisions and short subdivisions are recorded.

    A land use inspector will be assigned to your project and will work with you directly. Please contact the inspector to schedule inspections.
