Full Breakdown
In the EFU and Acreage Residential zones, MCC 17.136.100(A) and 17.128.060(A) set maximum height at 35 feet for dwellings and for non-farm structures, while farm-related structures on farm parcels have no height limit. For residential accessory structures, MCC 17.117.030(A) uses a sliding scale: the maximum peak height is nine feet at the lot line, increasing one foot for each foot of distance from the lot line up to a 35-foot maximum, with roof drainage kept on-site. Accessory structures in EFU, SA, FT, or TC zones must keep a 20-foot setback from all property lines. Height exceptions in MCC 17.113.120 allow taller chimneys, towers, antennas, and steeples.
Violations & Fines
Exceeding the height limit for your zone or structure type is a violation and may require redesign, lowering, or removal before final approval.
