On March 27, 2020, Governor Newsom issued an executive order banning the enforcement of eviction orders for renters affected by COVID-19 through May 31, 2020. The order prohibits landlords from evicting tenants for nonpayment of rent and prohibits enforcement of evictions by law enforcement or courts. It also requires tenants to declare in writing, no more than seven days after the rent comes due, that the tenant cannot pay all or part of their rent due to COVID-19.
