California Annexation by Cities

CALIFORNIA ANNEXATION BY CITIES

In California, the annexation of unincorporated county land by a city is a formal, state-regulated process designed to promote orderly urban development and efficient public service delivery. This process is governed by the Cortese-Knox-Hertzberg Local Government Reorganization Act of 2000 and overseen by a Local Agency Formation Commission (LAFCO) in each county. Annexation is a unique area of municipal law and experienced legal counsel can guide clients either supporting or opposing the annexation.

The Role of LAFCO

A Local Agency Formation Commission is an independent regulatory and planning agency with a primary mandate to discourage urban sprawl and encourage logical changes in governmental boundaries. Key responsibilities in the annexation process include:

Establishing “Spheres of Influence” (SOI): LAFCO determines the probable future physical boundaries and service areas for each city and special district. Annexation proposals must be consistent with the city’s adopted Spheres of Influence and its General Plan.

Municipal Service Reviews (MSR): Before updating a Spheres of Influence or considering an annexation, LAFCO conducts comprehensive reviews of municipal services (e.g., water, sewer, fire) to evaluate their adequacy and efficiency.

Approving or Denying Proposals: LAFCO reviews and ultimately approves, denies, or approves with conditions all annexation applications. It does not, however, initiate most boundary changes itself.

The Annexation Process

The process can be initiated by a city council resolution or by a petition from local landowners or residents, and generally follows these steps:

Initiation: The city council passes a resolution or a landowner submits an application to the city’s planning department. The property must typically be contiguous to the existing city limits and within its Sphere of Influence.

Planning & Environmental Review: The city’s Planning Commission reviews the proposal, considering land use, zoning, and compliance with the California Environmental Quality Act (CEQA).

LAFCO Application: A formal application, including detailed maps, service plans, and environmental documentation, is submitted to LAFCO.

Inter-Agency Negotiation: A crucial step involves the city and county negotiating the transfer of property tax revenues to compensate the city for assuming service responsibilities.

Public Hearings & Protest Proceedings: LAFCO holds a public hearing to review the proposal. Registered voters and landowners within the affected area have the right to protest the annexation.

Final Decision: If less than 25% of voters or landowners protest, the annexation is ordered without an election. If protests range from 25% to 50%, an election is held within the affected territory. If 50% or more protest, the proceedings are terminated.

Certification: If approved, LAFCO issues a Certificate of Completion, which is recorded with the County Recorder, making the territory officially part of the city.

Streamlined “Island” Annexations

To address the inefficiencies of “county islands” (unincorporated pockets substantially surrounded by a city), California law allows a streamlined process for annexing areas up to 150 acres without protest proceedings or elections, provided specific criteria are met.

Impact on Residents and Services

Annexation results in a change of governmental authority from the county to the city, often leading to:

Improved Services: Residents generally gain access to a full range of urban services like enhanced police and fire protection, street sweeping, and infrastructure maintenance, which are typically more robust than county provided services in urban areas.

Local Control: Residents gain local representation through city council members and the right to vote in city elections.

Potential Fee/Tax Changes: While property taxes generally do not increase due to the annexation itself, residents may be subject to different city fees, such as utility user taxes, building permit fees, or special assessments for specific city services.

Examples of Annexations

City of Huntington Beach: Huntington Beach annexed Sunset Beach, an unincorporated community, in a contentious process that began with a city council vote in 2010 and concluded in 2011, with the annexation becoming official on August 22, 2011. The annexation faced legal challenges from Sunset Beach residents who opposed being subjected to new taxes without a vote, but a lawsuit was ultimately rejected. Despite the legal battle, a majority of residents ultimately supported the annexation. Jennifer McGrath was the City Attorney for Huntington Beach charged with handling the legal challenges in the annexation of Sunset Beach.

City of Chino: Chino annexed about 145 acres of unincorporated San Bernardino County land, including the Ramona Avenue and Mustang Court area, on November 25, 2024.

City of Whittier: Whittier annexed approximately 90 acres of unincorporated Los Angeles County territory, including parts of Whittier Boulevard and West Whittier, which was approved by LAFCO on November 13, 2024.
