The CIF is adhering to the California Department of Health guidelines. These were last updated Jan 25th, after the shelter in place was lifted. I am sorry if I am giving inaccurate information but I would think the guidelines currently are based on the Jan 25th update. A cut and paste from their site:
Is scrimmaging or competition allowed?
Inter-team competitions (i.e., between two teams) may resume in California beginning January 25, 2021, based on the guidelines outlined in this document. The status of return-to-competition is subject to change at any time given the level of COVID-19 transmission in California.
Currently, there is no timeframe for when tournaments that involve more than two teams will be permitted in California.
Travel outside of California for competition is not allowed, several multistate & multi-jurisdictional outbreaks have been reported in CA residents and around the nation.
