In its latest Global Office Index (2Q15) publication, Jones Lang LaSalle IP (JLL) noted that the San Francisco peninsula was the market that achieved the greatest gains in terms of grade A office rents (up 25.5%) over the year to 2Q15. Rents in that market rose by 5.7% in 2Q15 alone.  The rise in grade A rents in downtown San Francisco were 10.3% year on year (or the 9^th largest rise of the 95 markets monitored) and 1.5% in 2Q15 (27^th). JLL attributed the gains to strong demand from technology companies.
