The six ballot measures facing San Francisco voters on Nov. 5 were given identifying letters by the city’s elections department Monday.

By law, bond measures get top billing on San Francisco ballots, followed by proposed Charter Amendments and then ordinance proposals.

On Election Day, voters will consider the city’s largest-ever affordable housing bond, whether to tax Uber and Lyft rides, an initiative mandating more campaign finance disclosures, among others.

Here’s the lineup of the local ballot measures:

Proposition A: Championed by both Mayor London Breed and the Board of Supervisors, Prop. A would allow the city to sell $600 million worth of bonds to build, rehabilitate or acquire affordable housing in San Francisco. The measure could lead to the construction of about 2,800 new affordable housing units in the next four years.

Proposition B: Sponsored by Board of Supervisors President Norman Yee, Prop. B would rename several city agencies that coordinate services for older adults and people with disabilities. If the measure passes, the Department of Aging and Adult Services would become The Department of Disability and Aging Services. The commission that oversees that department would similarly become the Disability and Aging Services Commission. The name changes are meant to provide a clearer sense of what the agencies do, so people will be more likely to seek out their services. Prop. B would also require that the commission contain at least one person 60 years of age or older, at least one person with a disability and at least one veteran.

Proposition C: Sponsored by e-cigarette maker Juul, the measure would put restrictions on sales of vaping products, limiting how many devices and cartridges can be purchased at a time and requiring online retailers that ship e-cigarettes to San Francisco to get an extra permit. The measure is meant to overturn legislation championed by Supervisor Shamann Walton and City Attorney Dennis Herrera that suspended the sale of e-cigarettes not reviewed by the FDA starting at the end of January 2020.

Proposition D: In an effort to ease some of San Francisco’s crippling traffic congestion, Prop. D would place a tax on every Uber and Lyft ride in San Francisco. The tax would vary between 1.5% and 3.25%, depending on the type of ride requested. The tax, which would be levied on the net fare of each ride, would bring in up to $32 million annually for transit improvements. Uber and Lyft agreed not to oppose the tax after extensive negotiations with Supervisor Aaron Peskin and his staff.

Proposition E: Prop. E would allow for 100% affordable and educator housing to be built on parcels of public land, where such projects are currently prohibited. As the city grapples with the twin crises of homelessness and ultra-high housing costs, the measure is meant to open up more of the city to affordable housing development. The measure was signed onto the ballot by four supervisors — Sandra Lee Fewer, Matt Haney, Shamann Walton and Aaron Peskin — and is supported by Breed.

Proposition F: Also known as the “Sunlight on Dark Money Initiative,” Prop. F would force independent expenditure committees — commonly referred to as Super PACs — to disclose who’s bankrolling their political spending. If the measure passes, the committees would have to disclose their top three donors when they pay for a political advertisement or other campaign-related materials. The measure would also place strict limits on contributions made by people or companies that have major land use matters — worth $5 million or more — before the city. Supervisor Gordon Mar is the measure’s main backer.
