A consortium of regional transportation and planning agencies could band together to buy a building in San Francisco to house their new headquarters.

The Metropolitan Transportation Commission, the region’s lead transportation agency, the Bay Area Air Quality Management District, which monitors pollution in the area, and the Association of Bay Area Governments are in talks of jointly purchasing a building at 390 Main St. in The City. According to the MTC, the joint purchase of the building would decrease costs for the agencies while improving energy efficiencies.  

The acquisition must be approved by the boards of each agency involved in the plan, but if authorized, the new building would be the site of regular meetings conducted by the departments. Currently, the MTC, which controls regional funding for transportation agencies in the Bay Area, meets in Oakland.

MTC spokesman John Goodwin said there has been no information released yet about how much the purchase would cost. Once the costs of the purchase have been detailed, they’ll likely be pretty hefty — the plan calls for headquarters with 350,000 square feet.
