Cal. Gov. Code § 53329.6

In order to reduce the procedural burdens on local agencies, this chapter establishes certain procedures by which one or more property owners may vote in favor of special taxes, bonded indebtedness, an appropriations limit, and annexation to a district by unanimous approval. The Legislature hereby finds and declares that any unanimous approval constitutes the vote of the qualified elector in favor of the matters addressed in the unanimous approval for purposes of the California Constitution, including, but not limited to, Articles XIIIA and XIIIC.
