Proposition K in California is not a single law. “K” is a letter that local elections officials assign to ballot measures in the order they qualify for a given city or county election, so the same label gets reused across jurisdictions and election years. A Proposition K in Los Angeles has nothing to do with a Proposition K in San Francisco, and two Proposition K measures in the same city a decade apart can address completely different subjects.
Why the Same Letter Keeps Appearing
California uses letters to identify local ballot measures within a single election cycle. The letters are handed out in sequence as measures qualify for a particular city or county ballot, and the alphabet resets between elections. “K” is simply the eleventh letter in that sequence and carries no special meaning on its own. Statewide propositions use numbers rather than letters, and no recent statewide proposition has used the “K” designation.1California Secretary of State. Ballot Measures
That reuse is why a search for “Proposition K” alone will not get you a clean answer. You need the jurisdiction and the election year. The three examples below show how far apart these measures can sit from one another.
Los Angeles Proposition K (1996): Parks and Youth Facilities
Los Angeles voters approved a Proposition K in November 1996 that created a citywide assessment district generating $25 million per year to acquire, build, improve, and maintain parks, recreation facilities, and cultural facilities serving youth. The assessment applies to all real property in the city over a 30-year period, which places the program in its final years of authorization. Spending is tracked through an LA For Kids Steering Committee.2City of Los Angeles Office of the City Clerk. Proposition K – LA For Kids Steering Committee
San Francisco Proposition K (2014): Affordable Housing Goals
San Francisco’s November 2014 Proposition K was a housing policy measure. It called for constructing or rehabilitating at least 30,000 new housing units by 2020, with at least one-third permanently affordable to low- and moderate-income households, and over half within financial reach of middle-class residents. It also directed the city to develop a funding strategy for affordable rental and homeownership housing, create a neighborhood stabilization trust to preserve existing rental affordability, and pursue a land acquisition strategy for affordable housing sites.3City and County of San Francisco.

The measure required the Board of Supervisors to hold an annual hearing on progress toward these goals and directed the Mayor to propose corrective strategies if the targets were not being met.3City and County of San Francisco.

San Francisco Proposition K (2024): Upper Great Highway Closure
Ten years after the housing measure, San Francisco put the “K” letter on something entirely different. The November 2024 Proposition K, referred to voters by the Board of Supervisors, permanently closed the Upper Great Highway between Lincoln Way and Sloat Boulevard to private vehicles and converted that stretch into public open recreation space.4SPUR. San Francisco Prop K – Upper Great Highway It passed with roughly 54.7 percent of the vote.5Ballotpedia. San Francisco County Proposition K – Close Upper Great Highway to Private Vehicles and Establish Public Open Recreation Space Measure
Three measures, three subjects: a 30-year property assessment for youth facilities, a housing policy declaration with reporting requirements, and a road closure. All labeled Proposition K.
How a Measure Gets the “K” Label in the First Place
A local measure reaches the ballot one of two ways. A city council, county board of supervisors, or other local governing body can refer a measure directly to voters, as the San Francisco Board of Supervisors did with the 2024 Upper Great Highway measure. Alternatively, residents can gather signatures from registered voters to qualify a citizen-initiated measure.1California Secretary of State. Ballot Measures
Signature thresholds for citizen-initiated local measures vary by jurisdiction. The Secretary of State directs anyone pursuing a local initiative to contact their county elections official or city clerk for the specific rules.6California Secretary of State. How to Qualify an Initiative Once a measure qualifies, it gets the next available letter in that election’s sequence. If “K” is next, “K” is what it gets.
Finding the Proposition K That Applies to You
Because the label is reused, there is no single document to look up. To identify the Proposition K that affects you, you need two pieces of information: the city or county where you voted (or where the measure was on the ballot) and the election year. With those, your county registrar of voters or city clerk can provide the full text, the voter guide analysis, and the certified results. The California Secretary of State maintains a directory of county elections offices.6California Secretary of State. How to Qualify an Initiative A web search combining your county name, “Proposition K,” and the election year will also usually surface the right measure.
If someone cites “Proposition K” without naming a jurisdiction and year, treat that as incomplete information. Ask which one.
