A night stay at the county jail costs the county $322. That’s one of the many fun facts the county supervisors were drenched with this Tuesday morning. That’s a little more than the Hilton Hotel charges and a little less than the Kimpton’s Canary. By contrast, a night at the county Psychiatric Health Facility (PHF) – better known as the “Puff Unit” – goes for about $2,600 a night. For what it’s worth, that’s slightly more than the room rate for the San Ysidro Inn, though admittedly these are off-season rates.
