Broomfield, CO Building Setbacks & Zoning: Setback Rules (2026)

Section 17-09-040 sets the minimum lot and yard requirements for the RR Rural Residential District, the zone intended under section 17-09-010 for large single-family lots that preserve a rural environment. A principal building needs a lot of at least 2.25 acres, 200 feet wide and 330 feet deep, with a 50-foot front yard, a 150-foot rear yard, a 25-foot side yard, and a minimum floor area of 1,400 square feet. Accessory buildings share the 150-foot rear yard but only need a 20-foot side yard, capped at 2,500 square feet of floor area.

Section 17-09-050 measures building height under section 17-38-320(F) and caps it at 33 feet. Section 17-09-060 layers on additional RR-specific rules: off-street parking under section 17-32-040, the sign code in chapter 17-44, and the fences, hedges, and walls provisions of section 17-32-140 all apply, local streets must meet the rural road section of the city's standards and specifications adopted in chapter 14-04, and a connection to the city water and wastewater systems is required unless the city council expressly grants an exemption. The land use review commission may approve variations to the lot and yard requirements as a use permitted by special review where buildings are clustered to preserve common open areas.
