Colorado Agricultural Land Right to Farm Protections

Under C.R.S. 35-3.5-101 et seq., agricultural operations existing for one year or more on agricultural land are protected from nuisance lawsuits if they were not a nuisance when established. Local governments cannot retroactively declare agricultural uses a nuisance. However, municipalities retain home-rule authority to regulate livestock in residential zones. The state defines agricultural land for tax purposes under C.R.S. 39-1-102(1.6). Counties typically permit chickens and small livestock on agricultural-zoned parcels without numeric limits.

Nuisance claims against protected operations are barred; cities imposing retroactive restrictions face preemption challenges.
