Cambridge Board Approves Biogen Headquarters Sign Variance With Midnight Lighting Limit

CAMBRIDGE — May 14, 2026 — Cambridge zoning board approves Biogen headquarters sign with nighttime curfew in unanimous vote. The Cambridge Board of Zoning Appeal voted 5-0 Thursday to grant biotechnology company Biogen a variance allowing an internally illuminated wall sign roughly 13 feet tall and 41 feet wide — approximately 540 square feet in area — near the top of its new global headquarters at 75 Broadway in Kendall Square, conditioning approval on the sign being turned off between midnight and 4 a.m. Chair Stephen Ng, who disclosed a conflict of interest letter filed with the city manager due to his employer's project management work for Biogen, read board findings that a conforming 60-square-foot sign would be rendered invisible by an unusual double row of street trees along Broadway. Member Wendy Leiserson, who accepted the wayfinding rationale on height and size, pushed for the nighttime restriction citing residential neighbors at 100 Memorial Drive and impacts on birds and insects, while the East Cambridge Planning Team and trustee Ovedia R. Sima of the East Cambridge Open Space Trust argued in letters that no prior non-conforming Kendall Square sign request had ever been granted, calling the proposal "a billboard." The board also voted 5-0 on both a variance and a special permit for a city Department of Public Works salt shed at Danaher Park designed to increase road-salt storage from 1,300 to 2,000 tons, and continued a 64 Winter Street residential addition case to June 25 after finding the applicant's drawings lacked standard dimensions, room labels, and an updated site survey.
