Michigan Agricultural Zoning and RTFA Preemption

MCL 286.474(6) provides that local units of government shall not enact, maintain, or enforce ordinances, regulations, or resolutions that conflict in any manner with the Right to Farm Act or GAAMPs developed under it. This preemption affects zoning rules attempting to ban farm operations, restrict farm structures, or set tighter setbacks than GAAMPs allow. However, the 2014 Site Selection GAAMP exempted primarily residential areas from livestock siting protections, returning some local zoning authority over urban livestock. Courts continue to interpret the boundary between protected farms and zoning.

Inconsistent local zoning is unenforceable against compliant farms; non-compliant operations remain subject to local rules.
