Proposition 45
Proposition 45
California · November 3, 2026
What this measure does
Establish timelines for local and state agencies to review plans and solicit public comment for essential projects, such as housing, improvements to water supply, transportation, energy, and facilities for health and public safety
A yes vote means
Government agencies must follow set timelines to review project plans and give the public a chance to comment before major housing, water, transportation, energy, and public safety projects move forward.
A no vote means
The government can continue its current practices for reviewing and approving these types of projects without the new timelines and public comment requirements this measure would create.
Simple explanation
This measure sets up rules so that when the government plans big projects—like building new homes, fixing water systems, or improving roads—they have to follow a timeline to show their plans to the public and let people give feedback before moving forward. Think of it like requiring a teacher to show a lesson plan to parents and get their input before teaching it, rather than surprising everyone with changes.
