S.F. Prop. A Authorizes the San Francisco Public Utilities Commission to issue bonds for clean energy projects, with approval from the Board of Supervisors.

S.F. Prop. B Requires appointed members of city boards and commissions established by the City Charter to give up their seats when they file to run for state or local office. Pros: Helps eliminate potential conflicts of interest and abuses of power while codifying a long-accepted, if unofficial, city policy. Cons: Forcing city commissioners and board members to relinquish their seats could dissuade them from running for higher office. The Chronicle recommends Yes on S.F. Prop. B Our editorial Our total coverage S.F. Prop. B

S.F. Prop. C Raises taxes on commercial landlords to 3.5 percent, mostly to fund child care and education. Pros: Helps relieve pressures on San Francisco families by providing a dedicated revenue stream of $146 million annually to fund and potentially expand early childhood education and caregiving services. Cons: The commercial real estate market is volatile, and commercial landlords could pass on additional costs to their tenants, potentially creating an incentive for them to relocate. Prop. C also competes with Prop. D — only the measure that secures the most votes will be enacted. The Chronicle recommends No on S.F. Prop. C Our editorial Our total coverage S.F. Prop. C

S.F. Prop. D Raises taxes on commercial landlords to 1.7 percent, mostly to fund housing- and homelessness-related services. Pros: Addresses San Francisco’s homelessness and housing-affordability crises by bringing in $70 million annually to fund homeless services and for low- to middle-income housing.

Prop. E Our editorial Our total coverage S.F. Prop. E

S.F. Prop. F Requires the city to establish, fund and operate a program providing legal representation to any residential tenant facing eviction. Pros: Creating a system that provides no-cost legal representation to anyone at risk of losing their home could help curtail displacement and ensure that tenants know their rights. Cons: The measure’s goals could be accomplished legislatively, and by law, future policymakers would not be required to fund such a program, which would cost between $4.2 million and $5.6 million annually. The Chronicle recommends No on S.F. Prop. F Our editorial Our total coverage S.F. Prop. F

S.F. Prop. G Authorizes the city to collect an annual parcel tax of $298 through 2038 for investment in the San Francisco Unified School District.

S.F. Prop. H Authorizes the San Francisco Police Department to purchase electronic stun guns and sets the city’s policy for using them. Pros: Would create a fixed timeline for equipping police officers with Tasers and for implementing the policies for their use. Cons: Would concentrate the policy-making power over the use of Tasers with the Police Officers Association, the SFPD’s union, and away from the Police Commission, the department’s policy-making body. If passed, the measure could only be amended by voters or a supermajority vote by the Board of Supervisors. The Chronicle recommends No on S.F. Prop. H Our editorial Our total coverage S.F. Prop. H
