In response to the recent COVID-19 public health crisis, Silverthorne Town Hall is closed to the public until further notice. However, the Town of Silverthorne is committed to servicing the building community during this time, and will take steps to allow essential construction activities to proceed, per CDC Guidance, and health measures defined by the Summit County Building Department’s inspection policies and procedures.

Technical permits , hot tub permits, and window permits (without a plan review required) may be submitted electronically.

Building permits (and commercial technical permits) that require plan reviews may be dropped off in the building department drop box located in the vestibule at the main entrance to Town Hall (601 Center Circle, Silverthorne, CO). We will do our best to review and issue permits in a timely manner. 

Sign permitting requirements for temporary signs needed in response to COVID-19 are currently being waived. Sign permits are not required from now until August 31, 2020 for temporary banners attached on all four corners to buildings and for sandwich board signs placed on private property in the commercial areas of Town. All other signs still need a sign permit. Prohibited signs, described in detail in Section 4-9-5 of the Town Code, are not permitted.  Examples of prohibited signs include flashing signs, moving signs, wind-driven signs, festoons, or off-premise signs.
