SACRAMENTO, Calif. — The greater Sacramento region will be placed under California’s most restrictive coronavirus rules this week because capacity in hospital intensive care units has fallen below 15%.

The 13-county region encompassing the state capital has an ICU capacity of 14.3% and will face a regional stay-at-home order at 11:59 p.m. Thursday, according to the state Department of Public Health website.

Under the restrictions, restaurants must stop outdoor dining, personal care businesses such as barbers must close and the number of people allowed inside stores is reduced. Residents are asked to stay home except for essential activities.

The huge Southern California and San Joaquin Valley regions are already in the strictest category, and several counties in the San Francisco Bay Area chose to implement their own voluntary orders independent of the state. The state is divided in to five regions for purposes of determining restriction levels based on ICU capacity.
