Revise the land use and planning act
SB 121 revises Montana's land use planning act, affecting local governments, developers, and the public involved in development projects. The bill clarifies that local governments may make decisions on development applications and provides additional opportunities for public comment on proposed developments by clarifying public notice requirements. It allows cities to retain extraterritorial zoning authority beyond their limits. Additionally, the bill amends land divisions excluded from subdivision review and allows for a public hearing before a planning commission hears an appeal.

MINOR
The bill was revised to include a new definition section and added a new statute section (76-25-104) to the list of amended laws. The most significant policy change is the addition of a termination clause that ends a city's authority to zone beyond its boundaries once the surrounding county adopts its own zoning regulations, preventing overlapping jurisdiction.
Scope change
The bill's scope was expanded to cover a specific termination condition for cities applying zoning beyond their limits, and the list of affected statutes was updated to include a new section.
DEFINITION
Added 'providing definitions' to the bill's summary, indicating new definitions will be included in the text.
SCOPE
Added section 76-25-104 to the list of statutes being amended.
REQUIREMENT
Added a requirement that a city's authority to zone beyond its limits ends when the county adopts its own zoning regulations.
