AB 2484 creates an explicit path for the San Diego Metropolitan Transit System (MTS) to impose a retail transactions and use tax across all or part of its service area either through action by the MTS board or via a qualified voter initiative. The measure ties the tax to the existing Transactions and Use Tax Law and Article XIII C of the California Constitution, sets rules for which subareas may be taxed, and fixes the tax’s effective date to the close of polls on the approving election day.
The bill also conditions tax‑financed construction contracts above $1,000,000 on commitments to use a skilled and trained workforce or apprenticeship occupations, preserves several project labor agreement (PLA) exceptions, and confines how revenues may be spent (only within the taxed portion and only on transportation/transit infrastructure and services). Finally, it requires tax proceeds to supplement — not replace — other transportation revenues for the same area, creating enforceable spending constraints that will affect budgeting and compliance.
At a Glance
What It Does
Permits the MTS board or a qualified voter initiative to impose a retail transactions and use tax within the board’s area under the Transactions and Use Tax Law and Article XIII C, with the tax becoming effective at the close of polls on the election day it is adopted. It adds procedural and substantive rules for partial-area taxes, contract workforce requirements on tax-funded projects over $1,000,000, and spending restrictions.
Who It Affects
Directly affects the MTS board, San Diego voters in areas that might be taxed, retail sellers and tax administrators who collect the tax, construction contractors bidding on tax‑funded projects, and labor organizations involved in apprenticeship and PLA arrangements.
Why It Matters
The bill expands how local transit agencies can place a dedicated sales tax before voters (including by initiative), embeds labor standards into the use of those proceeds, and narrows allowable uses — all of which shape who can bid on projects, how projects are financed, and how local governments account for transit funding.

What This Bill Actually Does
AB 2484 authorizes a local retail transactions and use tax for the full or a portion of the San Diego MTS service area under existing state transactions‑and‑use tax rules and Article XIII C. It clarifies that the tax can be placed on the ballot either by the MTS board or by a qualified voter initiative despite competing language in the Elections Code, and it instructs the relevant county to run the election in the usual manner.
The ordinance takes legal effect at the close of the polls on the day voters approve the proposition, with collections to begin according to the processes already established in state law.
When the tax would apply only to part of the MTS area, the bill requires tidy geographic lines: incorporated cities — or groups of contiguous cities with shared borders — must be included or excluded in whole, and the board’s entire unincorporated area must also be either fully in or fully out. The bill also preserves the board’s ability to re-submit the same or a different measure to voters if an earlier measure fails.On contracting, AB 2484 bars the board from entering any construction contract over $1,000,000 that is financed in whole or in part with these tax proceeds unless the contractor (and its subcontractors at every tier) gives an enforceable commitment to use a “skilled and trained workforce” or holds a contract that falls under an apprenticeship occupation defined by the Public Contract Code.
The measure lists exceptions where a project labor agreement already binds the parties, where the board itself requires a PLA, or where a contract continues under an older PLA entered into before January 1, 2019. The bill borrows the statutory definition of a PLA from existing public contracting law.Finally, AB 2484 constrains how proceeds are used: revenues must be spent within, or for the direct benefit of, the taxed portion of the MTS area and may be used only for transportation and transit infrastructure and services.
The bill adds an explicit anti‑supplanting rule: these revenues must supplement other transportation funds rather than replace them, which creates an accounting and enforcement obligation for local governments and the transit board.
The Five Things You Need to Know
AB 2484 allows the MTS retail transactions and use tax to be imposed either by board action or by a qualified voter initiative, notwithstanding Section 9300 of the Elections Code.
If approved, the tax becomes effective at the close of the polls on election day; initial collection follows the timing rules set in Section 120483 of existing law.
Partial‑area taxes must include whole incorporated cities (or wholly exclude them), treat contiguous cities as units when they share borders, and treat the board’s entire unincorporated area as entirely in or out.
The board may not award construction contracts over $1,000,000 financed by the tax unless the contractor provides an enforceable commitment to use a skilled and trained workforce or the work falls under apprenticeship occupations, with specified exceptions for project labor agreements.
All tax proceeds must be spent within (or for the benefit of) the taxed portion and only on transportation and transit infrastructure/services, and proceeds must supplement—not supplant—existing transportation revenues.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Authority to impose the tax under existing law
This subsection ties any retail transactions and use tax for the MTS area to the Transactions and Use Tax Law and Article XIII C, requiring the board to follow Section 120485 and other existing procedures. Practically, it means the tax mechanism follows the state’s familiar framework for local sales taxes rather than creating a bespoke tax; implementation will therefore rely on the same collection, reporting, and remittance systems already used by counties and the Board of Equalization/State tax agency.
Permits a qualified voter initiative route
This paragraph explicitly allows a qualified voter initiative to impose the same retail transactions and use tax, overriding the limitations that might be read from Section 9300 of the Elections Code. That change opens an alternate pathway for citizens, rather than solely the board, to place the tax before voters and could alter campaign dynamics and signature‑gathering strategies for local proponents and opponents.
Effective date and initial collection
The ordinance takes effect immediately at the close of the polls on the approving election day, and initial collections must conform to the established timetable in Section 120483. This creates a narrow and specific administrative trigger date that local tax administrators, vendors, and the MTS must coordinate around to ensure correct start‑of‑collection handling.
Geographic rules for partial‑area taxes
If the tax applies to only part of the MTS territory, the board (or the initiative language) must define that portion before voters decide. The bill requires whole‑city inclusion/exclusion, treats groups of contiguous cities as units where borders are shared, and requires the entire unincorporated area either be fully included or excluded. Those constraints aim to prevent checkerboard taxation, but they also require careful mapping and may force politically difficult inclusions or exclusions for particular municipalities.
Workforce and project labor agreement conditions on tax‑financed contracts
The board cannot enter construction contracts exceeding $1,000,000 where the tax will finance the work unless the contractor commits to using a skilled and trained workforce or the work is in an apprenticeship occupation as defined by the Public Contract Code. The provision lists four exceptions tied to project labor agreements (PLAs), including where a PLA already binds contractors or where a PLA predates January 1, 2019. The section cross‑references public contracting definitions to set the baseline for compliance and enforcement.
Spending constraints and anti‑supplanting rule
Revenues must be expended within or for the benefit of the taxed portion and may be used only for transportation and transit infrastructure and services. The anti‑supplanting mandate requires these proceeds to augment, not replace, other transportation revenues available to the same area, creating directed budgeting and audit responsibilities for the board and local governments that receive and use the funds.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- San Diego Metropolitan Transit System (MTS) board — gains an additional, legally specified revenue source and an alternate route (voter initiative) to put a funding measure before local voters.
- Residents and transit riders within a taxed portion — receive targeted funding for local transportation and transit projects that are restricted to benefit their area.
- Labor unions and registered apprenticeship programs — stand to gain from the skilled and trained workforce requirement and the PLA exceptions, which steer tax‑funded construction work toward contractors who use union or apprenticeship labor.
- Local contractors with established apprenticeship programs — get a competitive advantage on tax‑financed projects because they can meet the workforce commitment more readily than non‑participating firms.
- Cities included in the taxed area — obtain a direct source of funding for transportation needs within their boundaries, subject to the bill’s permitted uses.
Who Bears the Cost
- Consumers and businesses in the taxed area — bear the immediate economic cost through a higher local sales/use tax on retail transactions in the included territory.
- Retailers and tax administrators — face added collection, remittance, and compliance responsibilities tied to a new local transactions and use tax (and must coordinate timing when the tax becomes effective at close of polls).
- Nonunion/out‑of‑area contractors without apprenticeship capacity — may be effectively excluded from bidding on tax‑financed projects or incur costs to comply with workforce requirements.
- MTS board and local governments — assume administrative, oversight, and legal burdens to define taxed geography, enforce workforce commitments, administer spending rules, and defend potential legal challenges.
- Local transportation budgets and agencies — must maintain separate accounting to demonstrate that AB 2484 proceeds supplement rather than supplant existing transportation revenues, which can divert staff time and require new audit procedures.
Key Issues
The Core Tension
The bill sits at the intersection of two competing goals: broadening democratic access to tax measures (by enabling initiatives) and imposing practical constraints designed to direct tax revenue toward locally specified transit projects and higher labor standards. Expanding ballot access increases the chance of funding but also risks legal conflicts and fragmented geography; imposing workforce rules advances job quality but narrows the bidder pool and can increase project cost — forcing policymakers to trade political and social objectives against administrative complexity and fiscal trade‑offs.
AB 2484 packs several implementation challenges that are easy to understate. Allowing a voter initiative route despite Section 9300 invites litigation over statutory conflict or procedural compliance; courts could be asked to reconcile the Elections Code with this bill’s instruction.
Defining partial taxing areas with whole‑city and whole‑unincorporated‑area rules simplifies boundary lines but may produce politically awkward exclusions that prompt municipal challenges or require map redraws ahead of any election.
The workforce mandate is both blunt and consequential. Requiring an ‘‘enforceable commitment’’ to use a skilled and trained workforce shifts significant compliance and monitoring obligations onto the board and contractors, but the bill leaves open how those commitments will be verified and enforced in practice.
The PLA exceptions mitigate some competitive tension but could privilege contractors aligned with organized labor and raise procurement costs. Finally, the anti‑supplanting requirement creates a persistent accounting question: local entities will need clear standards and regular audits to prove that new tax dollars actually supplement existing transportation funds rather than replacing them — a fact pattern that has fueled disputes in other local revenue measures.
