California Code, Health and Safety Code - HSC § 1280.2

(a) No deficiency cited pursuant to paragraph (2) of subdivision (b) of Section 1280 or Section 1280.1 shall be for the failure of a facility to meet the requirements of the California Building Standards Code if, as of January 1, 1994, the hospital building was approved under Chapter 12.5 (commencing with Section 15000) of Division 12.5, or if the hospital building was exempt from that approval under any other provision of law in effect on that date.

(b) It is the intent of the Legislature that neither the amendments made to Section 1280 by the act that added this section, nor Section 1280.1 shall be construed to require the retrofitting of hospital buildings built prior to January 1, 1994, to meet seismic standards in effect on that date.
