Tips

  • Please allow a minimum of 10 to 15 days for permit processing per the county's own published guidance; alternate construction methods or commercial-scope projects may take longer.
  • A building/zoning clearance application may be extended up to 180 days (one extension) with a written, justified request; an issued building permit itself may be extended up to two times, each for up to 180 days, also requiring a written justified request before expiration.
  • If your lot is not on a public sewer, you must have an issued septic (onsite wastewater) permit or proof of sewer connection from the Environmental Services Unit before/alongside your building permit.
  • Plans must reflect the amended Table R301.2 criteria specific to your parcel's elevation (frost depth and ground snow load both scale with elevation) — confirm your parcel's elevation band before finalizing structural design.
