CA Gov't Code Section 66452.24

(a)

The expiration date of any tentative map, vesting tentative map, or parcel map for which a tentative map or vesting tentative map, as the case may be, that was approved on or after January 1, 2000, and that has not expired on or before the effective date of the act that added this section, shall be extended by 24 months.

(b)

Upon application of the subdivider filed at least 90 days prior to the expiration of the approved or conditionally approved tentative map or vesting tentative map, or parcel map for which the tentative map or vesting tentative map, as the case may be, that was approved on or before December 31, 1999, the time at which the map expires shall be extended by the legislative body or by an advisory agency authorized to approve or conditionally approve tentative maps, for a period of 24 months upon a determination that the map is consistent with the applicable zoning and general plan requirements in effect when the application is filed. If the map is determined not to be consistent with applicable zoning and general plan requirements in effect when the application is filed, the legislative body or advisory agency may deny or conditionally approve an extension for a period of 24 months. Prior to the expiration of an approved or conditionally approved tentative map, upon an application by the subdivider to extend that map, the map shall automatically be extended for 60 days or until the application for the extension is approved, conditionally approved, or denied, whichever occurs last. If the advisory agency denies a subdivider’s application for an extension, the subdivider may appeal to the legislative body within 15 days after the advisory agency has denied the extension.

(c)

The extension provided by subdivisions (a) and (b) shall be in addition to any extension of the expiration date provided for in Section 66452.6, 66452.11, 66452.13, 66452.21, 66452.22, 66452.23, or 66463.5.

Any legislative, administrative, or other approval by any state agency that pertains to a development project included in a map that is extended pursuant to subdivisions (a) and (b) shall be extended by 24 months if this approval has not expired on or before the effective date of the act that added this section. This extension shall be in addition to any extension provided for in Sections 66452.13, 66452.21, 66452.22, and 66452.23.
