California Proposition 218: Taxes, Assessments, and Fees

California Proposition 218, known as the Right to Vote on Taxes Act, is a 1996 constitutional amendment that requires local governments to obtain voter approval or property-owner consent before imposing or raising most local taxes, assessments, and property-related fees.¹ It added Articles XIII C and XIII D to the state constitution. In practical terms, a city council, county, or special district cannot quietly raise your property tax, sewer bill, or streetlight assessment. Specific notice, hearing, and approval procedures have to happen first, and if they don’t, the charge is vulnerable to challenge.

What Proposition 218 Actually Changed

Before 1996, local agencies had significant room to impose fees, assessments, and certain taxes without direct voter input, and residents who wanted to fight a charge in court had to prove it was illegal. Proposition 218 moved that fiscal authority from agency boards to the electorate and to affected property owners. It also reversed the courtroom presumption for assessments and property-related fees. Now the government has to justify the charge, not the resident who disputes it.²

The rules break down along three tracks: local taxes under Article XIII C, assessments on real property under Article XIII D Section 4, and property-related fees under Article XIII D Section 6. Each track has its own approval threshold and its own procedure.

Local Taxes: General Versus Special

Article XIII C sorts every local tax into one of two buckets, and the bucket determines the vote threshold.

A general tax funds the local government’s overall budget and can be spent on anything the agency chooses. A general tax needs approval from a simple majority of voters before it can be imposed, increased, or extended.³

A special tax is earmarked for a specific purpose, such as public safety, parks, or transportation. Because the money is locked to a narrow use and faces less ongoing budget scrutiny, the threshold is higher: two-thirds of voters must approve it.³ An agency cannot label a tax “general” to duck the two-thirds bar if the revenue is actually dedicated to a specific program. Courts look at how the funds are used, not the label the agency picks.

Special-purpose districts and school districts have an added restriction. They can’t levy general taxes at all. Every tax they impose is a special tax and must clear two-thirds.³

Assessments on Real Property

An assessment is a charge placed on a parcel to pay for an improvement or service that benefits that parcel directly, such as street lighting, landscaping, or flood control. Article XIII D Section 4 sets substantive limits that go well past a simple vote.

Special Benefit and Proportional Share

Before levying any assessment, the local agency has to identify every parcel that will receive a “special benefit” from the improvement and separate that benefit from any general benefit the wider public receives.² Only special benefits are assessable. If a new streetlight makes the whole area safer for anyone walking through, that general safety improvement can’t be billed to nearby owners. Only the portion of the benefit unique to specific parcels can be assessed.

Each parcel’s share must be proportional to the special benefit it receives, and no parcel’s assessment can exceed the reasonable cost of the proportional benefit conferred on it.² Assessments can’t be used to generate surplus revenue or cross-subsidize unrelated programs.

Engineer’s Report

Every proposed assessment must be supported by a detailed engineer’s report prepared by a registered professional engineer certified by the State of California.² The report calculates each parcel’s proportional obligation and provides the factual basis for the charges. Without it, the assessment is invalid on its face.

Government-Owned Parcels

Parcels owned by public agencies, the State of California, or the federal government aren’t automatically exempt. They can be assessed like private land unless the levying agency shows by clear and convincing evidence that the publicly owned parcels receive no special benefit.² That is a high evidentiary bar, and it exists to stop agencies from shifting costs onto private owners while quietly exempting their own land.

Property-Related Fees

Property-related fees are charges tied to owning property, most commonly water delivery, sewer service, and trash collection. Article XIII D Section 6 sets substantive limits on these fees whether the charge is new or already on the books.

Cost of Service, Not Revenue Generation

A property-related fee cannot exceed the proportional cost of providing the service to the parcel being charged.⁴ Revenue from the fee can only be spent on the service it was collected for. Total revenue across the service area can’t exceed total service cost. Fees also cannot be used to subsidize services provided to other customers, so a water district can’t charge residential accounts a blended rate that quietly covers commercial delivery costs.

Tiered Water Rates

Tiered pricing, where higher-volume users pay a higher per-unit rate, is common in California but faces real legal risk under Proposition 218. A water provider that charges more for heavier use has to show that heavier users actually cost more to serve. Justifying higher tiers on the social value of conservation alone isn’t enough. The rate differential has to trace back to real cost-of-service differences.⁴ Courts have held providers to a demanding standard here, requiring the cost calculations to be precise rather than merely reasonable.

The Sewer, Water, and Refuse Carve-Out

Not all property-related fees face the same approval hurdle. Fees for sewer, water, and refuse collection are exempt from the voter-approval requirement that applies to other property-related charges. Those three service categories only need to survive the notice-and-protest procedure. Every other type of property-related fee has to be approved either by a majority vote of affected property owners or by a two-thirds vote of the electorate in the affected area before it can take effect.⁵

Notice and Protest Procedures

For both assessments and property-related fees, the agency has to mail written notice to the record owner of every affected parcel at least 45 days before a public hearing. What happens at that hearing differs by charge type.

Assessment Ballots Are Weighted

Assessment notices include a ballot the owner can mark for or against the proposal and return to the agency. Assessment ballots use a weighted voting system: each ballot’s weight tracks the financial obligation assigned to that parcel, so it functions closer to a dollar-per-vote count than one-person-one-vote. If the weighted ballots opposing the assessment exceed those in favor at the hearing, a majority protest exists and the agency is barred from imposing the assessment.²

Fee Protests Are Counted by Parcel

Fee protests are simpler. There’s no weighted ballot. If a majority of owners of affected parcels submit written protests before the close of the public hearing, the agency cannot impose the fee.⁵ In many cases, tenants who directly pay the fee on a parcel can also submit a protest, but only one protest per parcel counts.

Even when a fee doesn’t require a formal ballot election, as with sewer, water, and refuse, a mobilized group of property owners can block it entirely through written objections. That creates pressure on agencies to keep proposed increases well-documented and defensible.

How Proposition 26 Expanded the Definition of a Tax

In 2010, voters approved Proposition 26, which broadened what counts as a “tax” under Article XIII C. Before Proposition 26, local governments could sometimes structure charges as regulatory fees or mitigation payments to sidestep the voter-approval rules. Proposition 26 now treats most government-imposed charges as taxes unless they fit within specific exceptions.³

The exceptions that are not treated as taxes include:

A charge for a specific benefit or privilege provided directly to the person paying, capped at the reasonable cost to the government of providing it.
A charge for a specific government service or product delivered to the person paying.
A charge covering the reasonable cost of issuing licenses, performing inspections, or conducting enforcement.
A charge for entry to or use of government property.
Fines and penalties for violations of law, including parking tickets and late-payment fees.
A charge imposed as a condition of property development.
Assessments and property-related fees that already comply with Article XIII D.

Anything outside those categories is now classified as a tax and has to run through the general or special tax approval process. The burden falls on the local government to prove a disputed charge qualifies for one of the exceptions.

Challenging a Charge in Court

Under Proposition 218, the local government carries the burden of proof when an assessment or property-related fee is challenged.²⁴ The agency has to show it followed the correct procedure, separated special benefits from general benefits, and kept charges proportional to costs. If it can’t, a court can invalidate the charge.

Water and sewer rates have their own compressed deadline. Under California Government Code Section 53759, any legal challenge to a new or increased water or sewer fee must be filed within 120 days of the effective date of the rate change or the date of its final adoption, whichever is later.⁶ Agencies that follow the Proposition 218 notice process for water and sewer must include a statement in the mailed notice informing owners of the 120-day deadline. The limitation applies to fees adopted or amended after January 1, 2022, and does not cover billing errors that come from defective implementation of an otherwise valid rate. For assessments and non-water, non-sewer fees, no similarly short deadline applies, but general principles of timeliness still matter.

Voter Power to Reduce or Repeal Existing Charges

Article XIII C Section 3 preserves the right of California voters to use the local initiative process to reduce or repeal any local tax, assessment, or fee. No other constitutional provision, including standard limits on initiative power, can override this right, and neither the Legislature nor a local charter can impose a signature requirement higher than what applies to statewide statutory initiatives.⁷

This works as a backstop. If a tax or fee was properly adopted but later proves excessive or unnecessary, residents can gather signatures, qualify a measure for the local ballot, and vote to cut or eliminate it. The initiative power reaches all local governments, including charter cities that might otherwise claim broader home-rule authority. Once a charge is on the books, it isn’t permanently untouchable.
