Historic District Design Standards Update

The City of Snohomish Design Review Board (DRB) has been working for several years on an update to the Historic District Design Standards. These standards are intended to promote awareness of the City's heritage; to protect the City's heritage by controlling alterations and demolitions; to rehabilitate and reuse historic structures; to encourage new construction in keeping with the City's historic character; and to attract visitors to Snohomish.  The existing standards were adopted in 2000 and updated in 2003.

Property owners and businesses are being asked to review the draft materials and provide comment by October 31, 2017.  These comments will be considered and discussed by the DRB at the November 8, 2017 regular meeting.  Some of the major changes in the draft documents (available in pdf format at the bottom of this page) are highlighted below.


• Standards broken into sections, with new construction separate from alterations made to existing buildings.
• More detailed description of the review process.
• More illustrative images added in each section.
