Full Breakdown
030, Table 2-4 (Residential Zone Development Standards) sets the maximum structure height by zone. The R-1 and R-1-5000 zones cap the main structure at 30 feet and accessory structures at 15 feet. The R-R zone without public sewer or water service allows 35 feet for both main and accessory structures, while R-R with public sewer/water is capped at 30 feet for the main structure and 15 feet for accessory buildings. Multifamily zones read higher: R-2 tops out at 45 feet, and R-3 and R-4 both allow 60 feet, still measured against the 15-foot accessory cap.
Mobile home (M-H) parcels are held to 15 feet for both main and accessory structures. 030(B) as the vertical distance from the average finished grade nearest the structure to its highest point. 030(C) lets certain structures exceed these caps: a place of assembly or meeting facility in a zone with a 35-foot limit or less can add up to 25 feet of extra height if every front, side, and rear setback is increased by one additional foot for each four feet of height added above 35 feet.
A separate list of miscellaneous structures, including flagpoles, cupolas, water tanks, fire walls, and roof-mounted mechanical equipment, may exceed the zone's height limit by up to 25 percent without a discretionary permit, though the Review Authority can impose a lower cap as a permit condition.
Violations & Fines
Building a house or accessory structure taller than the zone allows under Table 2-4 without an approved height exception is a Zoning Code violation, and the Planning Division can require the excess height removed or force a retroactive administrative or conditional use permit application before work continues. Height increases under § 18.30.030(C)(1) are void if the applicant does not also provide the extra one-foot-per-four-foot setback the section requires, exposing the structure to a setback violation as well.
