Boulder, CO Right to Farm: Agricultural Zoning Protection (2026)

Boulder's Land Use Code organizes all city land into seven classifications under Section 9-5-2(a): Residential, Mixed Use, Business, Downtown, Industrial, Public, and Agricultural. Table 5-1 assigns a single zoning district, Agricultural (A), to the Agricultural classification, tracing back to the former A-E district designation. Section 9-5-2(c)(7)(A) defines the district's purpose directly: agricultural areas in a natural state or in which the growing of crops, flowers, and trees or other farming activity is practiced. That single-sentence purpose statement is the entire substantive definition; unlike the code's residential or business districts, it carries no accompanying density, use mix, or intensity description in the classification section itself.

Permitted uses within the A district are instead controlled by Table 6-1's Schedule of Permitted Land Uses in Chapter 9-6, which cross-references the A column for each individual use type. Boulder's code does not contain a separate right-to-farm statute shielding agricultural operations from nuisance claims; a text search of the full municipal code for "right to farm" returns no results, meaning any nuisance protection for farming activity in the city would have to come from state law, specifically the Colorado Right to Farm Act, rather than from a local Boulder ordinance.

Property owners in the A district who want to build a detached dwelling unit, keep animals, or add accessory structures must check the specific use standards in Chapter 9-6 and the form and bulk standards in Chapter 9-7, since the Agricultural district purpose statement in Section 9-5-2 does not itself set setbacks, height limits, or lot coverage.
