This can be done by providing a copy of the Deed filed in the Auditor's Office or by obtaining a letter from the owner stating their willingness to allow you to place/build a structure on their parcel (reference parcel Number).

The Review Process

  • During the application process, or after the application is received, you may be asked for additional information or documents, if necessary.
  • The Application is reviewed by our Staff for completeness, and for compliance with other regulations and standards.
  • The construction plans are reviewed in detail. This can occur at the same time as the other reviews are being done.
  • Your plot plan is compared with the parcel as represented on county maps, to locate the project site relative to other mapped information, including
    • Zoning
    • Critical Areas (wetlands, bluffs, floodplains, creeks, rivers, streams, wildlife habitat, aquifer recharge areas ,hydric soils, erosions landslide and seismic soils)
    • Shorelines
    • Flood Hazard Zones
    • Water Rule area
  • Depending on the above map review, your project may require more in-depth review by a Planner. This may result in additional requirements to comply with the Zoning, Critical Areas, or Shoreline Ordinances, or other County, State and Federal laws. Requirements could include:
    • "Notice to Title", filed with the county Auditor disclosing critical areas on or near your parcel of land
    • Further studies or reports required prior to issuance of your permit (Wetland Delineation, Geotech Report, etc.)
    • Temporary fencing of wetlands or stream buffers

    • Drainage Plan approval
    • Road Approach, if necessary
    • Septic Approval (either an issued Septic Permit, or a satisfactory inspection of an existing system
    • Confirmation of Potable Water Availability (This may also trigger the need for a Mitigation Certificate for Dungeness Water Rule compliance.)
  • Once the above review steps are all completed satisfactorily, and construction plans are approved, all fees must be paid, and the permit will be issued.
