San Francisco Annual Budget Process: How City Funds Are Allocated

San Francisco operates under one of the most structurally complex municipal budgeting processes in California, driven by its unique status as a consolidated city and county, an unusually large number of voter-mandated spending requirements, and a two-year budget cycle that governs tens of billions of dollars in annual appropriations. This page explains how the budget is structured, who controls each phase, what legal constraints shape the outcome, and where the most contested tradeoffs occur. It draws on the San Francisco Charter, the Controller's Office, and the Board of Supervisors' published budget procedures.

Definition and scope

San Francisco's annual budget process is the formal governmental mechanism by which the City and County of San Francisco appropriates public funds across departments, enterprises, and programs for a given fiscal year. The fiscal year runs July 1 through June 30. The process is governed primarily by the San Francisco Charter, particularly Articles IX and X, which establish timelines, mayoral authority, and Board of Supervisors oversight roles.

The budget covers the General Fund — the city's primary discretionary account — as well as special revenue funds, enterprise funds (such as those supporting the San Francisco Municipal Transportation Agency and the San Francisco Public Utilities Commission), and grant funds including federal and state pass-throughs. San Francisco's adopted budget for Fiscal Years 2023–24 and 2024–25 totaled approximately $14.6 billion in combined appropriations (San Francisco Controller's Office, FY2023-25 Budget).

Scope and coverage limitations: This page covers the budget process as it applies to the City and County of San Francisco's consolidated government. It does not cover the independent budgeting processes of the Bay Area Rapid Transit District, the Golden Gate Bridge Highway and Transportation District, or other regional bodies that operate within San Francisco's geography but are funded and governed separately. California state budget allocations that flow into San Francisco are referenced only insofar as they affect local appropriation decisions — the state budget process itself is not covered here.

Core mechanics or structure

The San Francisco budget process unfolds across four overlapping phases involving the Mayor's Office, the Controller's Office, all city departments, and the Board of Supervisors.

Phase 1 — Instructions and projections (November–January): The Controller and the Mayor's Budget Director issue a joint Five-Year Financial Plan and budget instructions to all departments. Departments submit proposed budgets by the first Monday in February under Charter Section 9.101. The Controller's revenue projections — covering property tax receipts, business taxes, hotel and transfer taxes, and state and federal revenues — anchor the baseline that departments build against. The San Francisco Controller's Office publishes these projections publicly each fall.

Phase 2 — Mayor's proposed budget (February–June 1): The Mayor consolidates departmental requests and submits a proposed budget to the Board of Supervisors by June 1. Under Charter Section 9.101(a), the Mayor may not submit a budget that exceeds projected revenues without identifying a gap-closing plan.

Phase 3 — Board of Supervisors review (June–August 1): The San Francisco Board of Supervisors has until August 1 to adopt the budget. The Board's Budget and Appropriations Committee holds public hearings department by department. The Board may reduce or redirect appropriations but, under Charter Section 9.102, may not increase the total General Fund appropriation beyond what the Mayor proposed without a corresponding identified revenue source.

Phase 4 — Adoption and implementation: The full Board adopts the budget by ordinance, the Mayor signs or vetoes, and the Controller issues allotments to departments. Budget adjustments during the fiscal year require supplemental appropriation ordinances, which the Board must also approve.

Causal relationships or drivers

Three structural forces dominate the budget's shape before any political negotiation begins.

Mandated spending floors: San Francisco voters have enacted baseline appropriation requirements for specific functions through ballot measures. As of 2024, voter-mandated minimums apply to the Police Department, the Fire Department, the Library system, Children's programs (via the Children's Fund), and the Municipal Transportation Agency, among others. The San Francisco Budget and Legislative Analyst's Office estimated that mandated and formula-driven appropriations accounted for approximately 70 percent of General Fund spending in recent two-year budget cycles, leaving roughly 30 percent subject to discretionary allocation.

Fixed cost escalation: Pension contributions to the San Francisco Employees' Retirement System (SFERS) and health benefit costs for active and retired employees represent the largest year-over-year cost drivers. SFERS contribution rates are actuarially determined; when investment returns fall short of the assumed rate, the city's required contribution rises. The Controller tracks these obligations in the Five-Year Financial Plan.

State and federal revenue dependency: Roughly 40 percent of San Francisco's total budget is funded by state and federal sources, according to the Controller's annual budget summaries. Medicaid (Medi-Cal in California) reimbursements flowing through the San Francisco Department of Public Health represent the single largest intergovernmental revenue stream. Federal formula changes or grant reductions produce immediate structural gaps that the General Fund must absorb or offset.

Classification boundaries

San Francisco's budget distinguishes among four primary fund types, each with different rules governing use and transfer:

The Charter treats enterprise departments' budgets differently: the SFMTA, Airport, Port, and PUC submit budgets approved by their own governing boards before Board of Supervisors review, giving those bodies a degree of budget autonomy not available to general fund departments.

Tradeoffs and tensions

Discretion versus mandate: The accumulation of voter-mandated spending floors has progressively narrowed the Mayor's and Board's ability to reallocate resources during fiscal crises. When revenues fall, the mandatory spending minimums remain legally binding, forcing cuts to programs without ballot protection — including many that serve lower-income residents and are politically popular but not voter-protected.

Two-year cycle versus real-time conditions: The biennial budget, while providing planning stability for departments, creates inflexibility when economic conditions shift sharply mid-cycle. Departments that received two-year appropriations cannot easily absorb mid-year shortfalls without supplemental action.

Enterprise autonomy versus citywide priorities: Enterprise departments' semi-autonomous budgets mean that the Board's influence over, for example, San Francisco Municipal Transportation Agency fare policy or capital spending is indirect. The SFMTA's Board of Directors, not the Board of Supervisors, approves fare changes, creating situations where the city subsidizes SFMTA operations through the General Fund while having limited formal control over SFMTA's spending decisions.

Capital versus operating tradeoffs: Shifting costs from operating budgets to the capital budget — funded through bonds and debt — can relieve short-term General Fund pressure but increases long-term debt service obligations. The San Francisco Capital Planning Committee evaluates capital project prioritization, maintaining a 10-year capital plan that must be reconciled with operating budget projections.

Common misconceptions

Misconception: The Board of Supervisors can freely increase budget appropriations.
Correction: Under Charter Section 9.102, the Board may only increase appropriations for specific line items if it simultaneously identifies an equal reduction elsewhere in the General Fund or a new revenue source. The Board cannot unilaterally expand total spending.

Misconception: The budget process begins in June.
Correction: The public submission of the Mayor's proposed budget on June 1 is near the midpoint of the process. Department heads begin preparing submissions in November, and the Controller issues financial forecasts in the fall. The June 1 date is a Charter deadline, not a starting point.

Misconception: Enterprise department budgets are fully separate from taxpayer funds.
Correction: Enterprise departments are expected to be largely self-sustaining, but the city regularly subsidizes certain enterprise operations — particularly SFMTA — through General Fund transfers when fare revenues and other receipts fall short of operating costs.

Misconception: Voter-mandated minimums guarantee proportional increases.
Correction: Most baseline formulas tie spending floors to a percentage of General Fund revenue, not to service need or inflation. When revenues fall, mandated floors fall proportionally, which can reduce absolute funding even when the percentage formula is satisfied.

Checklist or steps (non-advisory)

The following sequence reflects the formal stages of the San Francisco annual budget process as established by Charter and administrative practice:

  1. October–November: Controller publishes Five-Year Financial Plan; Mayor's Budget Office issues departmental budget instructions.
  2. November–January: City departments prepare and internally review budget submissions.
  3. First Monday in February: Departments submit proposed budgets to the Mayor under Charter Section 9.101.
  4. February–May: Mayor's Budget Office conducts departmental hearings and reconciles submissions against revenue projections.
  5. June 1: Mayor submits proposed budget to the Board of Supervisors (Charter deadline).
  6. June–July: Board of Supervisors Budget and Appropriations Committee holds public hearings; department heads testify; public comment accepted.
  7. Late July: Full Board of Supervisors votes on amendments and adoption.
  8. August 1: Charter deadline for Board adoption.
  9. August: Mayor signs, vetoes, or allows budget to take effect without signature.
  10. July 1 (of applicable fiscal year): Budget takes legal effect; Controller issues departmental allotments.

Public comment may be submitted during Budget and Appropriations Committee hearings. The San Francisco public comment process page covers participation procedures in detail.
