Iron County, UT Right to Farm: Agricultural Zoning Protection (2026)

Section 17.30.010(A) states the I-A zone is intended to 'preserve existing agricultural land resources,' identify areas suited to competitive, economies-of-scale agricultural operations, and 'prevent the premature conversion of rural lands to urban use,' and it is deliberately paired with the county's general A-20 agricultural district so that reclassifying A-20 land to I-A is not treated as illegal spot zoning when it borders other A-20 parcels. The zone is not intended for areas near incorporated cities and does not accommodate residential use as a principal use; permitted and conditional uses come from the Table of Uses at Section 17.16.030.

Under subsection D, the minimum lot size is eighty contiguous acres, residential density cannot exceed one single-family dwelling per eighty acres (with worker and accessory dwellings requiring a conditional use permit), and all principal uses and structures, including animal waste facilities, must sit at least two hundred feet from the property line. Accessory structures instead follow the A-20 zone's setbacks. Chapter 17.30 layers additional livestock-specific rules onto I-A land, including animal-unit classifications, separation distances from public gathering places and residences, and odor-easement and CAFO permitting requirements administered through the conditional use permit process and the Southwest Utah Public Health Department.
