What stands out about safety in Alto
Alto relies on the Marin County Sheriff’s Office

Across the whole area it patrols, the Marin County Sheriff’s Office reported 359 property and 79 violent crimes in 2025, with property crime down 15% and violent crime up 16% since 2022.

Plan for inland flooding, too
FEMA rates expected storm and flood damage in Alto higher than in 83% of U.S. communities, with inland flooding, earthquakes and tsunamis the main risks. Be ready ↓
Written from the FBI data on this page. County and state agency figures cover their whole patrol area, not just this town, so they can’t be turned into a rate.
Alto is covered by the county
Alto has no police department of its own in the FBI’s data. Calls here most likely go to the Marin County Sheriff’s Office, and its numbers cover the whole area it patrols, not just Alto.
Crimes reported in the parts of Marin County it patrols: the towns and villages without police of their own.
Property crimes (burglary, theft, stolen cars)
Violent crimes (assault, robbery, rape, murder)
These are counts, not rates. The FBI doesn’t publish how many people each agency covers, so we can’t turn them into a per-resident figure or a Safety Grade. Source: FBI Uniform Crime Reporting, offenses known to law enforcement by county and by state agency.
