HB 2330 Missouri House · 2026 Regular Session

Modifies provisions relating to annexation

HB 2330 modifies Missouri's annexation laws by replacing sections 71.012, 71.014, and 71.015 with new provisions. It clarifies that cities, towns, or villages may annex adjacent unincorporated areas only if they are "contiguous and compact," excluding areas connected solely by narrow strips like railroads under 1/4 mile wide. The bill also allows certain cities to annex areas within two miles of their boundaries or nearby state correctional facilities under specific conditions, and requires petitions signed by all property owners or majority unit owners in common-interest communities before annexation hearings. These changes directly affect local governments seeking to expand their boundaries and property owners in unincorporated areas.

MINOR

The bill was amended to add specific population thresholds for applying the 'contiguous and compact' annexation standard, clarifying that certain cities with populations between 200,000-230,000 or 400,000-500,000 are subject to the standard perimeter test. The original text defining this standard was removed and replaced with this more detailed version. This change narrows the scope of when the standard applies, potentially making annexation easier for some municipalities while maintaining restrictions for others.

Scope change

The scope of the 'contiguous and compact' annexation standard was modified to apply only to cities, towns, or villages with specific population ranges (200,000-230,000 or 400,000-500,000 inhabitants), rather than applying universally.

ELIGIBILITY

Added specific population thresholds (200,000-230,000 and 400,000-500,000 inhabitants) that determine when the 'contiguous and compact' standard applies to annexations.

DEFINITION

Removed the original universal definition of 'contiguous and compact' that applied to all municipalities without population restrictions.

REQUIREMENT

Added new language specifying that the perimeter test (25% of perimeter contiguous) only applies to municipalities within the specified population ranges.
