California Code, Health and Safety Code - HSC § 1416.48

A licensee who does not intend to engage in activity requiring nursing home administrator licensure may file a request to place his or her license in inactive status. An inactive license is subject to all requirements for renewal, including payment of fees, but completion of continuing education is not required to renew an inactive license. However, proof of completion of 40 continuing education credits during the last two years shall be submitted together with an application for reinstatement of an active license.
