Summary
Land, farm buildings and structures used for agriculture are exempt from unincorporated Linn County's zoning rules, and state-designated agricultural areas are exempt from county zoning and building regulations entirely, except floodplain and land-division rules.
Agricultural use exempt. No regulation or requirement contained in this chapter, other than regulations related to land division, shall be construed to apply to land, farm houses, farm barns, farm outbuildings, or other buildings, structures, or erections which are primarily adapted, by reason of nature and area, for use for agricultural purposes, but only while so used. ...regulation or requirements that relate to any structure, building, dam, obstruction, deposit or excavation in or on the floodplains of any river or stream shall apply.

Full Breakdown
Under the county's agricultural exemption, no zoning requirement applies to land, farm houses, farm barns, farm outbuildings or other structures primarily adapted for agricultural use, so long as they're actually used that way: only land-division rules and floodplain construction standards still apply. Separately, land inside an agricultural area created under Iowa Code § 352.6 is exempt from county zoning and building regulations altogether, again except for floodplain rules. Together these protect working farms in unincorporated Linn County from most local zoning review; Cedar Rapids and the county's other cities apply their own zoning to any land within city limits.
Violations & Fines
There's no penalty for farming itself: the exemption applies automatically. Building in a floodplain or violating land-division rules without the exemption is a county infraction under § 107-160.
