California Code, Business and Professions Code - BPC § 3775.6

(a) A licensee may request that his or her license be placed in a “retired” status at any time, provided the license has not been canceled, and any outstanding fines, cost recovery, and monthly probation monitoring costs are paid in full.

(b) An individual with retired status is not subject to any renewal or reporting requirements.

(c) Once an individual is placed on retired status, all privileges to practice respiratory care are rescinded. If an individual practices with a “retired” license, the individual will be subject to discipline as prescribed by this chapter for the unlicensed practice of respiratory care.
