Zoning - As enacted, authorizes certain counties to adopt a resolution prohibiting a municipality or regional zoning commission from exercising zoning authority outside of the boundaries of the municipality. - Amends TCA Title 5; Title 6; Title 7 and Title 13.

HB 1720 would allow counties with fewer than 341,500 residents (per the 2020 census) to pass a resolution prohibiting municipalities or regional planning groups from controlling land use, development, or infrastructure rules outside city boundaries. If a county adopts such a resolution, any existing zoning plans or ordinances by cities or regional groups that extend beyond municipal limits would become unenforceable. The bill requires counties to pass this resolution via majority vote of their legislative body and allows for temporary agreements to handle ongoing projects. It does not apply to metropolitan counties or prevent counties and cities from making cooperative agreements for lawful purposes.
