Summary

Before Iron County issues a building permit for a home or non-agricultural business in the A-20, RA-20 or I-A zoning districts, Section 17.30.070 requires the property owner to sign and record a notarized acknowledgment agreement confirming that ranching, farming, swine and animal operations occur nearby and are entitled to continue.

These county ordinances apply to unincorporated areas of Iron County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

A.All lots and properties located within the A-20, RA-20, and I-A zoning districts proposed for the issuance of a building permit to construct buildings for human occupancy and non-agriculture businesses shall sign an acknowledgment agreement prior to the approval of the building permit application. ... B.The acknowledgment agreement shall include that farming, ranching, swine and animal operations and activities exist and may continue to operate, and that agricultural use in the RA-20, A-20 and I-A zones is a principle land use of the RA-20, A-20 and I-A zoning districts. The owner(s) of the property signing the agreement shall acknowledge that the following activities and practices occur, but are not limited to:1.Pesticide spraying (including crop dusting) by land and plane;2.Field and ditch burning;3.Machinery operations, including well pumps, and engines, at all hours for extended periods of time;4.Feeding of livestock, including storage of all types of feed; ... 15.That strong odors are part of normal agriculture, ranching, farming, swine and animal operations; and16.Greenhouses.

Full Breakdown

The acknowledgment agreement created by Section 17.30.070 is Iron County's right-to-farm protection: it runs with the land, must be filled out completely, signed with a notarized signature by the building permit applicant, and recorded with the Iron County recorder before the county will approve a building permit for human occupancy or a nonagriculture business in the A-20, RA-20 or I-A districts. Subsection B requires the owner to acknowledge that agriculture is 'a principle land use' of those districts and lists specific practices the owner is agreeing to accept, including pesticide spraying and crop dusting by air, field and ditch burning, machinery and well-pump operation at all hours, livestock feeding and feed storage, dairy operations, grazing, calving and lambing, fertilizing, composting, agricultural dust, nighttime operations, associated noise, flood irrigation and runoff that may flood adjacent property, strong agricultural odors, and greenhouses.

A copy of the recorded agreement must be submitted with the building permit application itself. Section 17.30.080 pairs this with a separate, voluntary odor-regulation program for large animal feeding operations that lets neighbors and operators use odor easements and best-management plans, but the recorded acknowledgment agreement is the mandatory step that puts new residents on formal notice before they move next to a working farm.

Violations & Fines

The acknowledgment agreement itself is a permit prerequisite rather than a separate criminal offense: Section 17.30.070 requires the building permit application to include the recorded agreement, so Iron County Planning and Zoning will not approve a building permit for a home or nonagriculture business in the A-20, RA-20 or I-A zones without it, and building without the required permit is separately enforceable as a zoning violation under Section 17.72.070.

Frequently Asked Questions

Do I have to sign anything before building a house near farmland in Iron County?
Yes, if the lot is zoned A-20, RA-20 or I-A. Section 17.30.070 requires a notarized acknowledgment agreement, recorded with the county recorder and submitted with the building permit application, confirming you accept that farming and ranching activities occur and may continue nearby.
What does the acknowledgment agreement actually list?
It names specific practices owners must accept, including crop dusting, field burning, round-the-clock machinery and well-pump noise, livestock feeding, grazing, calving, fertilizing, composting, agricultural dust, nighttime operations and strong odors, plus flood irrigation runoff that may reach adjacent property.
Can I sue a neighboring farm for nuisance after signing the agreement?
The acknowledgment agreement is not phrased as a blanket lawsuit waiver, but Section 17.30.080's related odor-easement provisions bar suits over large animal feeding operation odor unless the complainant proves a genuine health and welfare detriment within the required separation distance.
