In most Jefferson County residential districts the primary-structure height limit is 35 feet; R-2 is 30 feet, and accessory structures are capped at 25 feet. Multi-family structures reach 45 feet in R-3A and R-4. Chimneys, water towers and similar features are exempt.
Section 30 tables the primary-structure height per district: 35 feet in R-1, R-1A, R-1B, R-1C, R-3, R-3A, R-4 and the RR districts, 30 feet in R-2, and 80 feet in RR-1/4. Multi-family structures may reach 45 feet in R-3A and R-4. All other accessory structures are limited to 25 feet, and never more than the height of the primary structure. Section 2.L exempts chimneys, stacks, water towers, silos, elevators, monuments, spires and belfries (except in Planned Development) from the district height limits.
Exceeding the district height limit is a zoning violation requiring a variance or correction; building permits are reviewed against these caps before approval.
