Revise municipal zoning laws

This bill revises Montana's municipal zoning laws by updating how cities and towns establish, amend, or repeal zoning regulations, restrictions, and district boundaries. It requires public hearings with at least 15 days' notice before zoning changes take effect, though boundary-only changes can be adopted immediately by resolution. The bill also allows municipalities to combine zoning hearings with annexation hearings under specific conditions, such as when proposed land uses match county zoning or approved growth policies. Additionally, it repeals a previous provision that allowed citizens to protest zoning regulation changes, removing that specific protest mechanism from state law.
