Who We Are

2,500 Antennas and

The San Francisco Neighborhood Antenna-Free Union (SNAFU) is a grass-roots, city-wide coalition of individual residents and neighborhood organizations that works to prevent the placement of wireless antennas on or near residences, schools, health care centers, day care centers, senior centers, playgrounds, places of worship, and other inappropriate locations in the City and County of San Francisco.

SNAFU's work follows from the mounting evidence concerning the health and environmental effects of radiofrequency (RF) radiation used by cellular phones, cellular antennas and other wireless transmitters, as well as a commitment to responsive local government and community-based, democratic control over land use, zoning, and health & environmental issues.

News and Events

Wireless industry agrees to voluntary microcell antenna moratorium.
On February 13, 2007, Board of Supervisors President Aaron Peskin introduced legislation imposing a 45-day moratorium on microcell antennas throughout San Francisco, while the Planning Department and Board of Supervisors consider legislation that would require all microcell antennas in the City to undergo the Conditional Use permit process. Currently, microcell antennas require only Accessory Use permits which result in no public notification of antennas proposed for residential buildings. (Read the Feb. 23, 2007 article in the San Francisco Examiner here.) All 11 Supervisors co-sponsored Supervisor Peskin’s moratorium legislation.

On March 6, 2007, the day of the scheduled Board vote on the moratorium, Supervisor Peskin announced that the wireless industry had voluntarily agreed to suspend applications for microcell antennas and the Board therefore continued its vote on the Board-imposed moratorium for 45 days.

This marks a major victory for San Francisco residents who have been resisting the placement of microcell antennas on or near their residential buildings. Currently, antennas proposed for mixed-use apartment buildings at Fulton & Masonic near the Panhandle and Guerrero & 18th Street in the Mission are scheduled for hearings at the Board of Appeals on Wednesday, August 1, 2007 beginning at 5:00 p.m. in Room 416 at City Hall.

Stay tuned for more information on these two appeals as the microcell legislation process unfolds.
