Ducey said his decision is "based on what's best for Arizona" and that he "intends to reopen the economy successfully when this happens."

Ducey went on to say Arizona's approach to closure of non-essential businesses and urging residents to stay at home was a more measured response to the pandemic, which has helped our state keep case numbers low.

The modifications he announced include the partial reopening of retail establishments starting May 4, with curbside pickup and delivery. By four days later, the restrictions will loosen.

Dine-in at restaurants is expected to be resumed some time in May, with a best case scenario of May 12, Ducey said. When asked about other types of businesses, like gyms, barber shops and salons, the governor said there is no specific timeline in place for reopening, but he is also hopeful for the month of May.

The governor said increased testing is a key part of planning to reopen, and cited the upcoming "testing blitz" as a tactic in addressing the need for rapid diagnoses.

The stay-at-home order was initially set to expire on Thursday, April 30 after being put in place on March 31. It stated that Arizona residents must limit their time away from home while still trying to "stay connected."

“Our goal is to [re-open dine-in restaurants] sometime in May.”

Exceptions to that included those involved in "essential activities," work or volunteering in "essential functions," using any services or products provided by essential businesses, and employment if they are a sole proprietor or family-owned business who works in an office separate but is not open to serve the public.
