Summary
House Bill 2330, sponsored by Representative West, would change annexation law by raising the contiguous/compact threshold from 15% to 25%, bar additional contiguous annexations within 24 months, and repeal a petition-based annexation procedure in certain counties. Supporters cite infrastructure and land-rights concerns; opponents urge statutory clarification and note existing statutory protections.
Representative West presented House Bill 2330 to the House Committee on Government Efficiency on Feb. 9, 2026, proposing three primary changes to Missouri annexation law: increase the contiguous/compact threshold from 15% to 25%, prohibit a city from annexing an unincorporated area contiguous to an area it annexed within the prior 24 months, and repeal a petition-based annexation procedure available in certain counties.
West said the bill is designed to protect owners of large rural tracts and to slow what he called aggressive or "strip" annexation that can lead to higher-density development and strain on roads, schools and utilities. "What this will do is keep unincorporated areas where residents have invested in larger tracts of land— it will keep cities from coming into those larger tracts of land and working with developers and going against the county land use," he said.
Committee members largely supported the sponsor's intent but debated details. Representative Mayhew and Representative Wolfen expressed sympathy for the bill's goals while questioning whether 25% is the right numeric threshold; West said he originally preferred 35% but settled on 25% as a compromise. Representative Reed asked about equity concerns, noting annexation historically has been used to shift tax bases and affect lower-income communities; the sponsor said the bill does not directly address those inequities but that voting procedures remain in current law.
Members and witnesses pressed statutory clarifications. Representative Jacobs and Representative Smith asked whether the sponsor's strike-through edits on page 6 remove exemptions for certain county classifications; the sponsor described the edits as "cleanup language" and agreed to follow up.
Public testimony included Michael Gibbons, who testified in support on behalf of St. Charles County, and Richard Sheets, who urged clarification, noting current statutes include public vote protections and zoning safeguards and that voluntary petition annexations often still require an election or public process. Sheets told the committee that in many cities annexed property enters with the most restrictive zoning classification initially and then may be subject to rezoning processes.
The committee concluded the public hearing without taking a vote; the sponsor said he would follow up with members offline to clarify statutory language and county-specific impacts.
