SB 1169 Extends California Tentative Map Life to 48 Months: What It Means for Parcel and Subdivision Maps

A tentative map is the proposed subdivision layout that a city or county approves, usually with conditions, before the final map or parcel map records and the new lots legally exist.

On September 20, 2026, Governor Newsom signed SB 1169 by Senator Tim Grayson, which lengthens that shelf life for tentative maps that lead to final (tract) maps.

How long does a tentative map last in California today?

Through the end of 2026, Government Code 66452.6 gives an approved or conditionally approved tentative map 24 months. A local ordinance can add up to 24 more months. Other rules can stretch that time:

• Phased final maps. If the subdivider must spend at least a set amount on public improvements outside the map boundary (not counting frontage work on abutting streets), each phased final map filed extends the tentative map by 48 months, up to 10 years from approval. The statute sets the base at $236,790. It has risen every year since 2012 by the State Allocation Board’s Class B construction cost index, effective each March 1, and the amount that applies is the one in effect when your application was received. Ask your agency for that figure.
• Extensions on request. If you apply before the map expires, the agency can grant extensions totaling up to six years. Filing the application alone extends the map for 60 days or until the agency acts, whichever comes first.
• Paused time. A development moratorium imposed after approval, such as a sewer moratorium, does not count against the clock, up to five years. The agency may also stay the clock for up to five years while a lawsuit over the approval is pending.

Delivering the final map to the county surveyor or city engineer before expiration counts as a timely filing, even if recording happens later.

What does SB 1169 change, and when does it take effect?

SB 1169 was chaptered as Chapter 423, Statutes of 2026. It is a non-urgency bill, so under Article IV, Section 8(c) of the California Constitution it takes effect January 1, 2027. The chaptered text makes three changes to Section 66452.6:

• The initial life of an approved or conditionally approved tentative map becomes 48 months instead of 24.
• A local ordinance may add up to 36 months instead of 24.
• The new timelines apply to any tentative map that is not expired as of December 31, 2026.

As a declared matter of statewide concern, the change also binds charter cities. The phased map extension, 10-year cap, six-year extensions, and moratorium and lawsuit rules are unchanged.

For example, a tentative map approved on March 1, 2025 would expire on March 1, 2027 under the old 24-month term, before any extension. Because that map is still alive on December 31, 2026, the 48-month term applies and its base expiration moves to March 1, 2029. A map that expires before December 31, 2026 does not benefit, so if yours runs out before then, file an extension application first.

Worked example: a tentative map approved March 1, 2025

1. 1Approved: the tentative map is approved on March 1, 2025.
2. 2December 31, 2026: the map is still alive, so the 48-month term applies.
3. 3Old term: it would expire on March 1, 2027 under the old 24-month term, before any extension.
4. 4SB 1169 term: its base expiration moves to March 1, 2029.

Does SB 1169 extend tentative maps for parcel maps?

No. SB 1169 amends only Section 66452.6. Tentative maps for parcel maps fall under Government Code 66463.5, which the bill did not touch.

When a tentative map is required for a parcel map (local ordinance decides, under Gov. Code 66428), it still expires 24 months after approval, plus up to 12 months by local ordinance, with extensions on application of up to six years.

If your land division will record as a parcel map, plan around the old clock.

What is the difference between a parcel map and a final (tract) map?

Government Code 66426 sets the dividing line. A tentative map and a final map, often called a tract map, are required for a subdivision that creates:

• five or more parcels,
• five or more condominiums,
• a community apartment project with five or more parcels, or
• a stock cooperative conversion with five or more units.

A parcel map covers most other subdivisions, usually four or fewer parcels, unless the agency waives it under its local waiver procedure (Gov. Code 66428). Some larger divisions can also use a parcel map, for example when the land is under five acres, every new parcel fronts a maintained public street, and no dedications or improvements are required. Very large parcels (20 or 40 acres and up, with conditions) can qualify too.

A final map must be prepared by or under the direction of a registered civil engineer or licensed land surveyor and must be based on a survey (Gov. Code 66434). Civil engineers licensed after January 1, 1982 also need a land surveyor license to perform that survey (Bus. & Prof. Code 8731).

Our parcel and subdivision map services cover tentative, parcel, and final maps. Conditions of approval often call for subdivision improvement plans for streets, storm drains, and sewer mains before the map can record.

Can I use a lot line adjustment or merger instead of a parcel map?

Sometimes, and the process is usually simpler. A lot line adjustment moves the lines between four or fewer existing adjoining parcels without creating any new ones. Under Government Code 66412(d), the agency's review is limited to whether the resulting parcels conform to the general plan, any specific or coastal plan, and zoning and building ordinances.

No tentative, parcel, or final map is required; the adjustment is recorded by deed. A record of survey is needed only if Business and Professions Code 8762 requires one, for example when the field survey sets points or lines not shown on any recorded map, or finds material evidence or a discrepancy that the record does not show.

A merger combines contiguous parcels. A city or county may, by ordinance, allow the merger of contiguous parcels under common ownership without reverting to acreage, with a recorded instrument showing the merger (Gov. Code 66499.20.3). Separate rules starting at Section 66451.10 limit when an agency can merge parcels on its own.

New legal descriptions are only as reliable as the existing lines they start from, which is why a boundary survey is often the first step. Learn more about our lot line adjustment and merger services.

What is an SB 684 or SB 1123 small-lot subdivision?

Government Code 66499.41 requires a local agency to review a qualifying parcel map, or tentative and final map, ministerially: no discretionary review, no hearing.

SB 684 (Chapter 783, Statutes of 2023) created this path as of July 1, 2024. SB 1123 (Chapter 294, Statutes of 2024) expanded it as of July 1, 2025, and AB 130 (Chapter 22, Statutes of 2025) made further changes, including an optional remainder parcel that does not count toward the 10-parcel limit. The main conditions:

• 10 or fewer parcels and 10 or fewer residential units. ADUs and junior ADUs, if the agency allows them, do not count toward the 10.
• A multifamily-zoned lot of up to five acres, or a vacant single-family-zoned lot of up to 1.5 acres, substantially surrounded by qualified urban uses.
• A location in an incorporated city that includes part of an urbanized area, or in an urbanized area or urban cluster in a county of more than 600,000 people.
• New parcels of at least 600 square feet (1,200 if zoned single-family) unless the agency adopts a smaller minimum by ordinance.
• An average unit size of no more than 1,750 net habitable square feet.
• Public water and sewer service.
• A site outside listed areas such as wetlands and very high fire hazard severity zones.

What this means for your project

• If you hold an approved tentative (tract) map, find its approval and expiration dates. If it will still be valid on December 31, 2026, ask your planning department to confirm the recalculated date in writing.
• If your map expires before December 31, 2026, file an extension application before it lapses. SB 1169 does not revive expired maps.
• If your division will record as a parcel map, nothing changed. Budget for 24 months, plus any local extension.
• Use the extra time well. More time does not remove conditions of approval. Improvement plans, improvement agreements, and final map checking still come before recording.
• Pick the right path early. A lot line adjustment, parcel map, tract map, and SB 684 map each carry different costs and timelines. A feasibility study can sort that out before you commit.

Local ordinances, submittal requirements, and processing times vary by city and county, so confirm the details with your local agency. If you are weighing a lot split, a subdivision, or a boundary change, contact us about your parcel and we will help you work out which map or adjustment fits.
