State Preemption Index (2026)

Which states most aggressively preempt local ordinances? This index ranks all 50 states by the number of state-level rules that override what cities and counties can regulate — covering firearms, tobacco, plastic bags, minimum wage, immigration, and right-to-farm.

Scored from 2,872 state-tier ordinances across 50 states. Each “preempting rule” is a state law that explicitly bars or limits local regulation on a specific topic.

Methodology: a rule is counted as “preempting” if it falls within a preemption-heavy category (firearms, tobacco, single-use items, employment, right-to-farm, immigration) or its summary contains an explicit preemption phrase. State-tier data updated weekly. Each rule cites the controlling state statute.
