Moscone Expansion from 3rd and Howard

Moscone Expansion from 4th and Howard

It’s more than an expansion. It’s an attention-grabbing, attendance-getting masterpiece on a grand corner of San Francisco.

The iconic Moscone Center is being reimagined to deliver expanded, contiguous exhibition space, more meeting rooms, cutting-edge technology, sustainability and greater flexibility —all while retaining its reputation as a top sellout venue in the heart of the electric city of San Francisco. Slated for completion in 2018, the $551 million expansion will add more than 157,000 gross square feet of flexible meeting space. Minutes away from 22,000 of the city’s 33,000-plus hotel rooms, world-class shopping and dining, Moscone will remain fully operational during the expansion.  

The Future

The Moscone expansion will add more than 157,000 gross square feet of flexible meeting space to Moscone North and South on Howard Street, between Third and Fourth Streets.

  • The addition creates more than 500,000 gross square feet* to be used as contiguous exhibition space or flexible meeting space.
  • Expanded lobbies in Moscone’s North and South buildings will total approximately 60,000 square feet.*
  • Two new floors of column-free meeting space include a 50,000-square-foot ballroom.*

*All capacities are subject to change.

A new enclosed pedestrian bridge connecting Moscone Center above Howard Street, will provide enhanced circulation for convention attendees. The expanded facility will be designed to garner the highest LEED® certification possible.


Moscone Center will remain fully operational during expansion.

  • One million people each year utilize Moscone North, South and West buildings.
  • Located in the heart of San Francisco, Moscone Center is minutes away from world class shopping and dining, and walking distance to 22,000 of our more than 33,000 hotel rooms.
  • Moscone West offers more than 300,000 gross square feet of meeting and exhibition space and will not be a part of the expansion.
  • Moscone Center answers the call of today’s meeting attendees with a $4.5 million wireless system providing complimentary high speed service to 60,000+ devices at one time with peak performance.

It’s an attention-grabbing, attendance-getting, $500 million meetings masterpiece on a grand corner in San Francisco.
