Under San Francisco's Proposition M growth limit, commercial construction is restricted to an annual 875,000 sf. But according to published reports, city planning director Gerald Green has said that as much as 1.75 million sf of space might be freed up should one of two competing ballot measures to revise Proposition M get the green light.

Green was in meetings most of Monday and did not return phone calls from GlobeSt.com. Under current law, city planners will on Oct. 17 be able to begin another annual allocation of office space. That date is eagerly awaited by a set of developers with more than 3 million sf of proposed office projects.

A proposal sponsored by Mayor Willie Brown would temporarily loosen the city's growth limit, leaving the amount of allocated space unchanged but moving the effective date from Oct. 17 to Jan. 1. The move would let the city's planning commission approve 875,000 sf by the end of this year and an additional 875,000 sf beginning in January for 2001.
