State inspectors have cited Sage Mountain Senior Living 55 times (31 serious, 24 minor) and confirmed 34 complaints across 85 visits. In one case involving a resident's stay in 2020, inspectors found that required monthly weight checks had not been done for two months, and the resident lost 24 pounds without the home's weight-tracking system flagging it or the physician being told. The same resident fell four times in one month; only two of those falls were reported to the doctor, and blood glucose records were not sent to the physician until after the resident was hospitalized. In other confirmed cases, a resident's call for help went unanswered for about 30 minutes, and two residents went three hours without their morning medications. In another case, a resident who needed to use the bathroom could not be assisted by staff and called 911; staff confirmed the Hoyer lift could not be used because the bed had been set too low.
