AB 1198 replaces the current quarterly schedule for the Director of Industrial Relations’ (DIR) prevailing rate determinations with a semiannual schedule and limits the retroactive effect of those determinations to contracts awarded or with notice to bidders published after a July 1, 2027 effective date. The bill also creates a short administrative contest process: affected contractors, awarding bodies, or representatives can file a verified petition within 20 days of publication; the DIR must investigate or hold a hearing and issue a written determination within 20 days (unless parties agree to a longer period), and determinations take effect 10 days after issuance.
The bill exempts certain deed-restricted or subsidy-restricted affordable housing projects from the new semiannual rule and instead places those projects under a distinct quarterly rule in new Section 1773.65; for those projects the DIR’s quarterly determinations remain nonretroactive for contracts where notice has already been published or the contract has been awarded. For procurement officers, contractors, and labor representatives the bill shifts the balance between rate stability and responsiveness, shortens administrative timelines for disputes, and adds operational complexity around the transition and carve-outs.
At a Glance
What It Does
Substitutes a semiannual cycle for prevailing-wage rate changes, makes new determinations apply only to contracts awarded or with bids noticed after July 1, 2027, and creates a 20-day verified-petition process with a DIR determination due within 20 days (unless extended by agreement). Determinations become effective 10 days after issue and remain until changed by the DIR.
Who It Affects
State and local awarding bodies that manage public-works contracts, contractors bidding on public works, union and nonunion craft representatives, and the Department of Industrial Relations (DIR). Affordable housing projects that are 100% deed- or subsidy-restricted are subject to a different quarterly treatment under Section 1773.65.
Why It Matters
The change reduces the frequency of rate updates that can alter contract costs mid-procurement, shortening windows for retroactive application; it also imposes strict administrative deadlines and a formal, expedited contest procedure that will affect bid timing, budgeting, and compliance workflows for public construction projects.

What This Bill Actually Does
Under current California law the DIR issues prevailing per diem wage rates quarterly and those determinations become the standard for public-works contracts, except they do not apply to contracts for which notice to bidders has already been published. AB 1198 rewrites that timing: the bill moves rate updates to a semiannual schedule and says those semiannual determinations only apply to contracts awarded or whose notice to bidders is published after July 1, 2027.
That change reduces how often prevailing rates will shift in the middle of procurement cycles.
The bill gives parties a short, structured way to challenge a new rate on a particular contract. Within 20 days after a new rate is published, any contractor, awarding body, or representative of an affected craft can file a verified petition with the DIR saying the rate was not determined according to the law.
The petitioner must provide the factual basis, and within two days a copy of the petition goes to the awarding body. The DIR must notify interested parties (including recognized collective bargaining representatives), investigate or hold a hearing, and issue a written determination within 20 days unless all interested parties agree to a longer period.
Once issued, the DIR’s determination is final and becomes effective 10 days after its issue date; it stays in force until the DIR changes it.The bill adds a carve-out for certain affordable housing developments. Projects in which 100 percent of units (excluding managers’ units) are deed- or regulatory-restricted or subject to housing subsidy agreements are not governed by the new semiannual Section 1773.6.
Instead, AB 1198 creates Section 1773.65, which retains a quarterly determination process for those housing projects but explicitly provides that a quarterly determination is not effective for any contract for which notice to bidders has already been published or that has already been awarded. The bill therefore treats affordable housing projects differently: they keep a quarterly cadence but preserve nonretroactivity for already-noticed or awarded contracts.Two practical outcomes flow from these mechanics.
First, public-procurement officials and contractors should expect fewer mid-cycle wage adjustments but must watch the July 1, 2027 transition closely to determine which contracts are affected. Second, the compressed administrative timeline for petitions (20 days to file, 20 days for DIR determination, 10 days to effective date) creates pressure on the DIR and parties to resolve disputes quickly; parties can agree to extend the DIR’s decision window, but absent agreement the statute compels speed.
The Five Things You Need to Know
The bill replaces a quarterly prevailing-rate update schedule with a semiannual schedule and limits those updates to contracts awarded or with notice to bidders published after July 1, 2027.
Affected contractors, awarding bodies, or craft representatives have 20 days after publication to file a verified petition with the DIR challenging a rate; a copy must be filed with the awarding body within two days of filing.
The DIR must notify interested parties (including recognized collective bargaining representatives), investigate or hold a hearing, and issue a written determination within 20 days of the petition—unless all interested parties agree to a longer period.
A DIR determination is effective 10 days after its issue date and remains in effect until the DIR modifies, rescinds, or supersedes it.
Projects in which 100% of units (excluding managers’ units) are deed- or subsidy-restricted for low- or moderate-income households are carved out: Section 1773.65 preserves quarterly determinations for those projects but bars those determinations from applying to contracts where notice to bidders has already been published or the contract has already been awarded.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Phase-out language for the old quarterly rule
Section 1 revises the existing statutory text to mark the current quarterly- determination rule as becoming inoperative and sets repeal language—language that creates a statutory transition from the old quarterly regime to the new scheme created later in the bill. Practically, this provision signals the legislature’s intent to retire the prior version of Section 1773.6 and replace it with the new timing and mechanisms in Section 2; agencies and contracting entities should track the operative/repeal dates in the enacted text to determine which regime controls for active procurements.
Semiannual determinations, petition process, and effective-date rule
This is the operative heart of AB 1198. It requires the DIR to publish changes on a semiannual basis and limits the retroactive application of those changes to contracts awarded or whose notice to bidders is published after the bill’s effective date (stated in the bill as July 1, 2027). The section creates a 20-day verified-petition right to contest a rate on a specific contract, obligates the DIR to notify the awarding body and recognized labor representatives, and directs the DIR to investigate or hold a hearing and issue a final written determination within 20 days unless the parties agree to extend the timeline. The determination must show an issue date and becomes effective 10 days after issuance; it remains binding until changed by the DIR.
Affordable housing exclusion from the semiannual rule
Section 2(d) excludes housing development projects in which 100 percent of units (excluding manager units) are restricted as affordable (by deed, regulatory restriction, or subsidy agreement) from the new semiannual framework. That exclusion prevents the semiannual rule from applying to these projects and delegates their treatment to the new Section 1773.65. The practical upshot is that affordable housing projects will be governed differently while nonrestricted public works follow the semiannual cadence.
Quarterly treatment for specified affordable housing projects with nonretroactivity
Section 1773.65 makes clear that the contest mechanics in subdivision (b) of Section 1773.6 apply to the excluded housing projects, but it also preserves a nonretroactivity protection: the DIR’s quarterly determination will not take effect for any contract where notice to bidders has already been published or which has already been awarded. This creates a hybrid approach: affordable housing projects remain on a quarterly update schedule, but the DIR’s quarterly changes cannot be applied to contracts already underway—reducing the chance of surprise cost changes for awarded or already-noticed housing contracts.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Awarding bodies (state and local public owners): Fewer mid-procurement wage updates reduce the risk that a prevailing-rate change will increase bid costs after a notice to bidders is published, improving budget predictability for public owners.
- Contractors bidding on public works: Less frequent (semiannual) rate changes lower the chance that a published bid will be upended by a subsequent DIR rate change, reducing short-term cost volatility during procurement windows.
- Recognized collective bargaining representatives: The bill requires the DIR to notify and may involve bargaining representatives in DIR investigations and hearings, preserving their ability to participate directly in rate challenges.
- Affordable housing developers with fully restricted projects: The separate treatment under Section 1773.65 shields awarded or already-noticed affordable-housing contracts from quarterly rate changes, reducing retroactive exposure for those specific projects.
Who Bears the Cost
- Department of Industrial Relations (DIR): The statute imposes compressed timeframes (20 days to decide, 10-day effectiveness) and procedural obligations (notice, hearings, written determinations), increasing DIR’s administrative burden and pressure to resolve technically complex rate disputes quickly.
- Contractors and awarding bodies handling fast-moving procurements: They must monitor publication closely and may need to file time-sensitive petitions or adjust procurement schedules to avoid falling within a new determination’s effective window.
- Labor unions seeking more frequent updates to wage rates: Moving from quarterly to semiannual updates delays the calendar for capturing wage shifts, potentially disadvantaging workers in rapidly changing local labor markets.
- Compliance and legal teams for public agencies and contractors: The new petition mechanics, deadlines, and carve-outs create new procedural traps and documentation obligations that will raise compliance costs and may generate more administrative appeals or writ petitions.
Key Issues
The Core Tension
The central tension is between procurement predictability and wage responsiveness: making determinations semiannual stabilizes bid pricing and reduces retroactivity risk for public owners and contractors, but it slows the system’s ability to reflect real-time local wage changes that can matter to workers and unions; the bill’s short administrative timeline seeks to limit disruption but may undermine the depth and fairness of rate reviews.
AB 1198 trades update frequency for procurement stability, but the mechanics create implementation friction. The compressed timelines—20 days to file, 20 days for the DIR to decide (unless extended by unanimous agreement), and a 10-day lag before a determination takes effect—put substantial pressure on DIR staff to investigate potentially complicated local wage facts quickly.
That speed could result in cursory investigations or greater reliance on parties’ submissions and stipulated agreements, which changes the nature of the administrative record supporting a prevailing rate. The bill permits extensions only by agreement of the director, awarding body, and all interested parties, which practically hands the parties a veto over extended review time but risks uneven bargaining power determining whether an extension occurs.
The carve-out for 100% deed-restricted or subsidy-restricted affordable housing projects both simplifies and complicates matters. On the one hand, it protects awarded or already-noticed affordable-housing contracts from retroactive rate changes; on the other hand, it creates a two-track system that procurement officers must navigate—determining which projects qualify for the carve-out, tracking deed restrictions and subsidy agreements, and applying different timing rules to similar projects.
The bill text itself contains inconsistent date markers (instances of July 1, 2026 and July 1, 2027 appear in different provisions), which introduces legal ambiguity until final enrolled text or conforming amendments resolve the inconsistencies. That ambiguity matters for contracts straddling the transition date.
Finally, while the statute labels the DIR’s determinations as final administratively, it does not eliminate judicial review avenues; however, the speed and finality language may shift dispute resolution toward prelitigation administrative maneuvering (e.g., tactical petitions and quick settlements) and could increase the use of extraordinary writs challenging administrative finality. Parties should expect a period of adjustment as procurement officers, contractors, labor representatives, and the DIR test the new procedures and clarify how the timelines operate in practice.
