ProcedureParcel Maps
Section § 66463
This law explains how local governments in California can manage the processing and approval of parcel maps. The rules and procedures are mainly determined by local ordinances, but there's a reference to specific sections for dedications on maps. Local agencies have the option to allow designated officials, like the county engineer or surveyor, to approve or reject these dedications. If a legislative body is responsible for approval, the procedure for final maps applies. There are also strict time limits for approving tentative and non-tentative parcel maps, as specified in other sections.
Section § 66463.1
This law states that if you have an approved or conditionally approved tentative map, you can file multiple parcel maps for it before the tentative map expires. You can do this in two ways: either by letting the advisory or local agency know in writing when you file the tentative map that you plan to file multiple parcel maps, or by agreeing with the local agency after filing the tentative map to submit multiple parcel maps.
You don't need to specify the number or layout of these parcel maps upfront. Filing a parcel map for part of the tentative map doesn’t invalidate the rest. The local agency still has the power to apply reasonable conditions when you file multiple parcel maps.
Section § 66463.5
This law outlines the rules around the expiration and extension of tentative maps required for dividing land into parcels. Initially, a tentative map expires 24 months after approval, but local laws may extend this up to 12 more months. If it expires, all proceedings stop unless a new map is processed. Subdividers can apply for an extension before it expires, which can prolong the map's validity up to six years in total, with an automatic 60-day extension during the review of their application. If an advisory agency denies an extension, the landowner can appeal to a legislative body within 15 days.
If a development moratorium (e.g., water or sewer issues) arises after approval, normal expiry is paused during the moratorium, not exceeding five years. Once the moratorium ends, the map is valid for the remaining period or at least 120 days. The expiry period is also paused during lawsuits if a local agency approves a stay on the timeframe, which can last up to five years.
