Safety and Crime Prevention

Neighborhood Safety leads to peace of mind

These programs help build strong and safe neighborhoods.

Neighborhood Watch

The Los Altos Neighborhood Watch Program supports strengthening neighborhoods to reduce crime. A cooperative program between Los Altos residents and the Police Department, Neighborhood Watch encourages individual neighborhoods to unite and form their own Neighborhood Watch Groups. 

In most cases, these groups will be the same group who formed a BAT (Block Action Team).

If you’re interested in joining the Los Altos Neighborhood Watch Program, please submit a Neighborhood Watch Information Form or contact Crime Prevention at (650) 947-2775. The Los Altos Police Department will work with you to create a new Neighborhood Watch Group or connect you with your Block Captain if a group already exists.
