Restaurants in Washington state that want to reopen must create a "daily log" of their customers' comings and goings.

Washington Gov. Jay Inslee's office issued a set of coronavirus requirements that restaurants must abide by when they reopen, to aid in any contact tracing, should that become necessary.

Under other Phase 2 rules, hand sanitizer must be available to employees and customers, restaurant tables must be placed far enough apart that guests at one table can maintain a 6-foot distance from guests at another, it is “strongly suggested” that customers wear a cloth face covering any time they are not seated at the table, buffets and salad bars are not allowed, and menus and condiments must all be single-use. Bar seating is not permitted.

In addition, restaurants are required to screen employees for signs of COVID-19 at the start of every shift.

Each employer also needs to designate a COVID-19 supervisor to monitor the health of employees and enforce the job site safety plan.

The state mandates that all restaurants demonstrate they can meet all requirements laid out in its COVID-19 safety plan before they will be allowed to reopen.

All parties and tables must be five guests or less. Guest occupancy must be 50 percent of the maximum building occupancy or lower, as determined by the fire code. Outdoor seating does not count toward the building occupancy limit.

Tables must be placed far enough apart when measured from occupied chair to occupied chair, to ensure guests are 6 feet away from one other. It is strongly suggested customers wear a face covering any time they are not seated at the table.

Buffets and salad bars are not permitted at this time but might be addressed down the line. Single-use menus are required for in-person dining and any condiments typically left on the table must be single-use or sanitized after each use.
