AB 1658 amends multiple sections of the California Public Contract Code to remove the temporary sunset, the limit on the number of contracts that may use expanded change-order authority, and the required review report for the Counties of Los Angeles and Santa Clara. The bill preserves — and makes indefinite — the option for each county to elect higher single-change-order dollar caps ($400,000 for contracts over $25 million and $750,000 for contracts over $50 million), with both figures adjusted annually by the California Consumer Price Index.
Why this matters: the measure shifts more discretion over large contract modifications to local county engineers and district officers while reducing immediate legislative oversight. For procurement teams, contractors, and county finance officers, AB 1658 changes who signs off on big cost swings, how many projects can rely on the higher caps, and how accountability will be tracked going forward.
At a Glance
What It Does
Deletes the January 1, 2027 repeal that would have ended special change-order rules for Los Angeles and Santa Clara, removes statutory language capping the number of contracts that can use the expanded caps, and eliminates the mandated review reports to the Assembly and Senate. It leaves in place higher dollar thresholds for change orders that counties may elect and requires local anti-fraud and accountability measures when authority is delegated.
Who It Affects
County boards, county engineers and district officers in Los Angeles and Santa Clara; contractors and subcontractors on high-dollar public construction projects (notably contracts over $25 million and $50 million); county finance and audit teams responsible for tracking change-order spending and compliance.
Why It Matters
The bill materially changes procurement governance for two large California counties by making temporary, higher delegation limits permanent and removing reporting and aggregate-use restraints that previously constrained the program. That alters risk allocation, internal controls, and the oversight footprint for large public-works projects.

What This Bill Actually Does
AB 1658 works through targeted edits and repeals across five provisions of the Public Contract Code to make special change-order rules for the Counties of Los Angeles and Santa Clara indefinite. Under current general law, change-order authority for most local agency construction is tiered and capped (small contracts: $5,000; mid-tier: 10% up to $250,000; larger contracts: a base amount plus a percentage, with a hard ceiling).
In recent statutes those two counties were allowed to opt into higher single-change-order ceilings for very large contracts; AB 1658 removes the temporary end date for those allowances so the higher ceilings remain available permanently.
Mechanically, the bill preserves the numeric thresholds introduced in prior sessions: counties may elect to permit county engineers or designated officers to approve change orders up to $400,000 on contracts originally priced over $25 million and up to $750,000 on contracts over $50 million. Those dollar caps are indexed to the California Consumer Price Index so they adjust annually.
When a board delegates authority under these provisions, the delegate’s decision is binding on the county, and existing protest and grievance processes continue to apply; boards must also establish ‘‘appropriate measures’’ to prevent fraud and ensure accountability at the time of delegation.Two of the most consequential shifts are procedural rather than numeric. First, AB 1658 deletes language that had limited the program’s use to a total of seven modified contracts across the listed sections — removing that aggregate cap allows an indefinite number of projects to utilize the expanded change-order authority.
Second, the bill eliminates a statutory requirement that the two counties file a review report with the Assembly Committee on Local Government and the Senate Committee on Governance and Finance by July 1, 2026. Together these changes increase local discretion and reduce the immediate flow of program-level information to the Legislature.The bill applies its changes across multiple chapters that govern ordinary county construction, county highways, certain district contracts, and specialty county functions (bridges, subways, waterworks, flood control).
It keeps intact ordinary bid-and-bond requirements, protest rights, and the existing smaller-tier caps for projects below the very large-contract thresholds; what changes is primarily who can sign off on very large change orders and how many projects can do so without triggering the prior aggregate limitation.
The Five Things You Need to Know
The bill preserves the higher single-change-order caps for Los Angeles and Santa Clara — $400,000 for original contracts over $25 million and $750,000 for original contracts over $50 million — and indexes both amounts annually to the California CPI.
AB 1658 deletes the statutory aggregate cap that previously kept the sum of modified contracts using the expanded authority to no more than seven contracts; after enactment there is no numeric limit in statute.
The requirement that either county provide a review report to the Assembly Committee on Local Government and the Senate Committee on Governance and Finance by July 1, 2026 is removed.
The bill amends or repeals parallel provisions in five code locations (Public Contract Code Sections 20142, 20395, 20405, 20614, and 20998) so the expanded change-order authority applies across general county construction, county highways, district contracts, and certain county-controlled water and flood facilities.
When boards delegate the expanded authority, the delegate’s decision is binding on the county and the board must implement ‘‘appropriate measures to prevent fraud and ensure accountability’’ at the time of delegation — a statutory obligation without detailed procedural standards in the text.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Makes county general construction change-order rules permanent and removes contract-quantity limits
This provision replaces the temporary 20142 text and deletes the sentence that would have repealed the section on January 1, 2027. It keeps the baseline tiered change-order caps for ordinary contracts and preserves the option for Los Angeles and Santa Clara to elect the two higher, CPI-indexed ceilings for very large contracts. Crucially, the section removes the clause that limited the total number of contracts that could be modified under the higher caps, converting what had been a time-limited, quantity-limited experiment into standing law for those counties. The practical effect is to allow repeated use of the higher thresholds across projects without triggering automatic statutory expiration or hitting the prior seven-contract ceiling.
Extends higher authority to county highways and clarifies delegation mechanics
Section 20395 governs county highway contracting methods and delegation to road commissioners or civil engineers. AB 1658 preserves standard procurement options while leaving intact the higher caps for large highway contracts if the County of Los Angeles or Santa Clara elects them. The text reiterates that delegated approvals are binding on the county and that protest and grievance procedures still apply, but it removes the seven-contract aggregate limitation previously linking use across code sections. For transportation teams, that means change orders on major highway contracts can now rely on the elevated dollar caps more broadly and repeatedly.
Applies expanded caps to bidding and award procedures and removes sunset
Section 20405 concerns bid openings, bidder security, performance bonds, and change-order limits tied to the road commissioner/delegation framework. AB 1658 preserves the existing bidding safeguards (sealed bids, bidder security, performance bonds) while ensuring the higher change-order ceilings are available for very large contracts under local election. The provision also deletes the section’s previous January 1, 2027 repeal date so the bidding-related language and the expanded change-order authority coexist indefinitely in the statute.
Covers districts and district officers; keeps binding-delegation rule and CPI indexing
Section 20614 extends the same structural changes to certain districts (for example, utility or water districts) and to their general managers or district officers. The section retains the tiered caps for ordinary contracts and gives Los Angeles the option to adopt the elevated CPI-indexed caps for very large contracts. Like the other amended sections, it removes the temporary sunset language and the prior limit on how many contracts could use the heightened authority, increasing the number of district-led projects that can rely on delegated change orders.
Applies change-order rules to district boards and chief engineers; preserves protest rights
Section 20998 focuses on district boards and chief engineers for specialized districts (for instance, flood control). The amendment keeps the structured tier of caps, allows Los Angeles to elect into the higher thresholds for very large contracts, and reiterates that the decisions made by delegated officers are binding. The section preserves existing protest and grievance mechanisms, so affected contractors retain legal avenues to contest specific decisions even as the statutory cap and sunset constraints are removed.
Special-statute justification for differential treatment
The final sections supply constitutional-style findings explaining why Los Angeles and Santa Clara require special treatment. They cite size, contract scale, and schedule constraints — particularly Los Angeles’s massive population and infrastructure footprint — as the rationale for deviating from a uniform statewide rule. Those findings matter because they frame the bill as a special statute under Article IV, Section 16 of the California Constitution and preemptively address challenges to unequal legislative treatment of specific counties.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- County chief engineers and delegated officers in Los Angeles and Santa Clara — gain durable authority to approve larger change orders without repeated board action, speeding approvals on very large projects and reducing administrative delay.
- Large contractors and construction managers working on projects above $25 million — face fewer procedural stops for approving substantial change orders, which can accelerate work and reduce scheduling bottlenecks.
- County project teams and program managers — obtain predictable, permanent delegation rules and CPI-indexed caps that simplify budgeting assumptions for multi-year, large-dollar projects.
- Districts that manage water, flood control, and specialized infrastructure in the affected counties — benefit from parity with county-level delegation through parallel code sections, enabling coordinated responses in emergencies or time-sensitive work.
Who Bears the Cost
- County taxpayers and local general funds — face higher fiscal exposure because more projects can use elevated change-order caps indefinitely, increasing the potential for aggregate unplanned spending without legislatively mandated review.
- County boards and elected officials — lose a statutory quantity-based constraint and the automatic reporting trigger, shifting political and legal accountability for large change orders onto delegated officers and local oversight systems.
- Smaller contractors and bidders — may encounter greater competition pressure on large projects where change orders can be approved quickly for incumbent contractors, potentially disadvantaging new entrants seeking thorough review.
- County auditors, internal controls and compliance units — bear the operational burden and cost of designing, implementing, and enforcing the ‘‘appropriate measures’’ against fraud and for accountability that the statute requires but does not define.
Key Issues
The Core Tension
The central dilemma is between operational flexibility for large, schedule-sensitive counties and public accountability over public dollars: AB 1658 gives county officials faster, broader authority to approve sizable change orders (promoting speed and continuity), but it reduces statutory limits and legislative reporting that previously constrained aggregate use and ensured state-level oversight, thereby increasing fiscal and governance risk unless counties build robust internal controls.
AB 1658 trades a tight, time-limited experiment in expanded delegation for a permanent, county-controlled framework. That raises practical questions the text does not fully resolve.
The statute requires boards to implement ‘‘appropriate measures to prevent fraud and ensure accountability’’ when delegating, but it provides no procedural standards, reporting formats, audit frequencies, or minimum internal-control practices. Counties will need to translate that high-level mandate into enforceable policies — a nontrivial administrative lift that will determine whether the bill increases effective oversight or merely relocates opacity from Sacramento to county offices.
Removing the seven-contract aggregate cap eliminates a blunt constraint that helped limit program scale; in its absence, there is a risk of steady, incremental reliance on elevated change orders across many projects. While individual caps are larger than prior ceilings, they are still finite; however, multiple large change orders across many contracts can produce substantial cumulative exposure.
The bill also strips the Legislature of an explicit mandatory reporting mechanism (the July 1, 2026 review), reducing centralized visibility into how often the higher caps are used, for what purposes, and with what fiscal impact. That will make ex post oversight dependent on county-level transparency, audit processes, and the will of local officials to publish data.
Operationally, the CPI indexing removes the need for frequent statutory updates but guarantees that the dollar thresholds will drift upward over time. That drift is likely intended to preserve purchasing power, but indexing without caps on growth or periodic legislative checkpoints can widen the gap between the authority delegated and the original policy rationale.
Finally, because the bill is a special statute for two named counties, it increases asymmetry in California procurement law — a feature the findings defend as necessary, but one that invites scrutiny over equal treatment and consistency of procurement principles across jurisdictions.
