Full Breakdown
Bellingham Municipal Code § 20.30.040(E) sets the height limit for the Residential Single (RS) zone at 35 feet under the code's height Definition No. 1, measured from grade at the building wall to the roof peak, or 20 feet under Definition No. 2, measured from the highest grade within 20 feet of the building.
