Pub. Resources Code, § 30600.1

(a) In the event that an applicant for a coastal development permit had, prior to January 1, 1982, received from the appropriate local government final discretionary approval to proceed with a proposed development, but had not been issued a coastal development permit prior to that date, the provisions of subdivision (b) or (c) shall apply to any requirements for housing for persons or families of low or moderate income which may be applicable to the proposed development.

(b) In the event that the commission has approved an application for a coastal development permit, but the applicant has not complied with conditions in regard to such housing which were imposed by the commission as part of its approval, the applicant shall do either of the following:

(1) Comply with the housing and other applicable conditions imposed by the commission, in which event the coastal development permit shall be issued and the provisions of Section 65590 of the Government Code shall not apply to the development.

(2) Apply to the appropriate local government as provided in Section 65590.1 of the Government Code to have that local government apply the requirements of Section 65590 of the Government Code to the proposed development, in which event, no condition previously imposed by the commission with respect to such housing shall be applicable to the proposed development.

(c) In the event that application has not been acted upon prior to January 1, 1982, the commission shall process the application as otherwise required by this division, but shall not impose any condition or requirement with respect to housing for persons or families of low or moderate income on the proposed development. The applicant shall apply to the appropriate local government as provided in Section 65590.1 of the Government Code to have that local government apply the requirements of Section 65590 of the Government Code to the proposed development. The commission, at its discretion, may defer action on this application until the local government has acted to apply the requirements of Section 65590 of the Government Code. The time limits otherwise applicable to commission action on this application shall be stayed during any such period of deferral. If however any such application is for a conversion of a residential dwelling as defined in paragraph (1) of subdivision (g) of Section 65590 of the Government Code, the commission shall not defer processing of such application but shall defer the final issuance of a coastal development permit until the local government has applied the requirements of Section 65590 of the Government Code.
