Housing

Angela Alioto: Supports the late Mayor Ed Lee’s commitment to build 5,000 units a year. Backed the general idea of state Sen. Scott Wiener’s SB827, a bill that would have lessened cities’ ability to block housing developments near public transit and that died in committee last month — but Alioto said it would have to be amended to include only areas within half a mile of a transit station. Supports raising height and density limits on some transit corridors, including Geary Boulevard in the Richmond and 19th Avenue in the Sunset.

London Breed: Has pledged to continue Lee’s commitment to build 5,000 units a year. Supported SB827. Has pushed legislation that gives current residents a “local preference” in affordable housing lotteries. Fought to close down the McDonald’s at Haight and Stanyan streets, a property that will be redeveloped as affordable housing.

Jane Kim: Supports expanding rent control to buildings constructed after 1978 and says she plans to introduce a $1 billion housing bond for the 2019 ballot. Opposed SB827, characterizing it as a developer giveaway that would have led to displacement.

Mark Leno: Would work to create 5,000 units a year of “low-income, workforce and supportive housing units annually.” Supports market-rate housing development only if an equal number of affordable units are built. Supported aspects of SB827 but ultimately opposed it, saying the “one size fits all” land-use policy wouldn’t work. Supports increases in affordable-housing requirements for projects on public land.

Tech

Alioto: Would create groups of city officials, tech industry representatives and residents to propose ways to lessen socioeconomic tensions created by the tech boom without hampering the industry. Says tech’s financial largesse should be funneled directly into projects that address the city’s most pressing problems, such as homelessness and street cleanliness.

Breed: Points to her legislation capping the length of time people can rent rooms through Airbnb as evidence that she’ll be tough on tech outfits — the company counts wealthy tech investor Ron Conway among its backers. Says the tech industry needs to provide more jobs to young San Franciscans and advocates a program that would provide paid internships for high school students at any company of their choice.

Kim: Says tech companies should raise wages and boost benefits for contract employees such as shuttle drivers and cafeteria workers, to help close the city’s wealth gap. Wants ride-hailing companies such as Uber and Lyft to pay a per-rider fee to the city as compensation for using public infrastructure.

Leno: Wants to spread the industry’s wealth and jobs, particularly to longtime city residents. Has proposed creating local-hiring requirements for the tech industry, saying it would reduce pressure on the housing market and transit.

Transportation

Alioto: Would block off a large stretch of downtown to automobiles and turn the streets over to buses, trolleys, bikes and other alternatives to cars. Thinks the head of the Municipal Transportation Agency, Ed Reiskin, is incompetent, would fire him and order an audit of the agency.

Breed: Has sponsored Muni nuts-and-bolts legislation as a supervisor, such as expanding and replacing the Metro fleet, reconfiguring seating on N-Judah trains, and expanding morning commute service between Cole Valley and the Embarcadero. Supports a city vehicle licensing fee to raise money for transit. Wants the city to analyze the traffic impacts of ride-hailing companies as a possible prelude to limiting the number of cars they can put on streets.

Kim: Was the lead sponsor of a 2014 Vision Zero resolution to add protected bike lanes, crosswalk signals, education for drivers of large vehicles and other pedestrian safety measures. Supports congestion pricing — charging people to drive on busy streets at certain hours — to raise money for transit improvements.

Leno: Wary of newer alternatives to public transit, taxis and cars, such as ride-hailing services and electric scooters, because they’re private outfits using public infrastructure with little or no compensation to the city. Is skeptical of the bus rapid transit line on Geary Boulevard and says the city should look at building a new subway line instead. Is also pressing the city to enact a vehicle licensing fee to raise money for public transit.

Homelessness

Alioto: Would close all city shelters and spend the money on permanent housing for homeless people, with an emphasis on the supportive type that offers on-site counseling to help chronically troubled people overcome their dysfunctions. Wrote the city’s 10-year plan to end chronic homelessness in 2004, and though that didn’t end the problem, it did help pull 19,500 homeless people off the streets.

Breed: Promises to eliminate homeless camps from streets within a year by moving occupants into low-cost or supportive housing. Says chronically mentally ill street people should be put into court-ordered conservatorship. Says her administration would build at least 5,000 housing units a year.

Kim: Would expand Behavioral Health Court, which steers mentally ill people and addicts into assistance programs instead of jail. Proposes 1,500 new shelter beds and increasing stock of affordable and supportive housing through actions including leasing units and crafting quick-to-build modular complexes.

Leno: Says he can eliminate street homelessness in two years by quick-starting the creation of 15,000 affordable, workforce and supportive housing units. Would pay for it in part with $100 million from Proposition 63, a 2004 state ballot measure that raised taxes on the richest Californians to improve the state’s mental health system. The measure is tied up in a court fight.

Budget

Alioto: Would provide tax breaks to small businesses by reallocating money from departments, including Public Works and the Municipal Transportation Agency. Says merchants have suffered from widespread construction, and public works and the MTA are bloated fiefdoms.

Breed: Would raise minimum wage for the city’s 22,000 in-home care workers, nonprofit employees and workers at San Francisco International Airport to $15.50 an hour, which would cost around $14 million. Wants to find $4.3 million to provide free legal help to people facing evictions. Backs Proposition D, which would raise taxes on commercial landlords to bring in around $70 million annually for homelessness and housing services.

Kim: After voting against a 2015 proposal to tie the size of the police force to increases in the city population, Kim now supports raising the police budget to hire more officers. Says any growth should be accompanied by more spending on social-welfare initiatives such as after-school programs. Would give more money to City College of San Francisco to expand its free tuition program into the summer sessions. Spearheaded Proposition C, which would raise taxes on commercial landlords to fund early childhood education and care services.

Leno: Wants to move to a “zero-based” system in which agencies build their spending for the coming year from scratch, instead of using the previous year’s spending plan as a template.
