What the state has logged
California has logged 11 state visits for this home as of August 2, 2026. These are the home's own counts, straight from that record — shown beside the statewide median for larger communities (16+ beds), computed across all 1,244 licensed homes of that size, because larger and longer-licensed homes naturally accumulate more visits and reports. They are facts, not a grade — a citation may be minor and since corrected, and an “unsubstantiated” complaint is not a finding of wrongdoing. No substantiated complaints are on file.
