HB 1166 Oklahoma House · 2025 Regular Session

Cities and towns; annexation; procedures; annexation of territory without consent of majority of owners; effective date.

HB 1166 changes Oklahoma city and town annexation rules by requiring written consent from a majority of landowners (65% for municipalities under 12,000 people) before adding territory. It mandates cities to create and implement service plans for water, sewer, fire, and police within 120 days of annexation, or risk detaching the area if services aren’t completed. The bill also prohibits annexing "connecting strips" of land solely to create legal contiguity and specifies detailed notice and hearing procedures for property owners.

MODERATE
The bill was amended to add stricter annexation rules, including a prohibition on using connecting strips for annexation, a population-based limit on annexation size for smaller municipalities, and new requirements for service planning and public notice. These changes aim to prevent municipalities from expanding through narrow land connections and to ensure smaller towns don't annex areas beyond their capacity to provide services.
Scope change
The bill now applies different annexation rules based on municipality population size, with stricter limits for towns of 12,000 or fewer residents.
REQUIREMENT

Added prohibition on annexing land via connecting strips that serve no municipal purpose other than establishing contiguity or capturing territory within the annexation area.

Modified notice requirements to include a service plan detailing water, sewer, fire protection, and law enforcement services that must be completed within 120 months or territory must be detached.

Added requirement that service plans be included in published notices and that completion timelines be set in the annexation ordinance.

ELIGIBILITY

Added population-based annexation limits: municipalities with 12,000 or fewer residents may only annex up to 8 square miles at one time with higher consent thresholds (65% of acres and 25% of population).

TIMELINE

Modified public hearing timing requirements to be held 14-30 days after notice publication and mailing.
