Condo board fumigates building.  How much notice do owners need?

Depending on state code or laws, a question for California HOA.  The board has decided to go ahead and have building service by a termite company.  They are doing this in sections - is there a time frame or amount of time that the board of directors have to notify owners when this will happen to their unit?  One owner's unlt was given a seven day notice to vacate unit for a minimum of three days.
