Why we like it

The waterfront setting is genuinely distinctive among California senior living options, and the community backs it up with one of the strongest safety records in the state.

Exceptional safety record
Cardinal Point holds an FYI Safety Score of 9.8 out of 9.9, one of the highest scores in California. At 153 beds, maintaining this level of compliance is remarkable.
Waterfront island setting
Alameda is an island city in the Bay with a small-town feel, walkable neighborhoods, and waterfront views that most senior communities simply can't match.
Large community with full resources

Bay Area accessibility
Alameda is centrally located in the East Bay with bridge access to San Francisco, Oakland, and the broader Bay Area, making family visits convenient.
Premium pricing
