Concord's listing runs to 19 office units in 2 buildings, sized from 5 to 230 m² with a median of 58 m² — a median suite large enough for seven or eight desks without subdividing. Concentration in just 2 buildings is the risk to manage: once a floor is taken the shortlist shrinks quickly, so it pays to enquire against the full set of 19 units rather than a single room.
Concord rents fall in a tight band: $233 to $338 per m² a year, median $285. On the median 58 m² suite that works out close to $16,500 a year before services, and a gap of about 45% between the low and high rate is narrow enough that chasing the cheapest number rarely justifies accepting a worse floor or a longer commute.
Address choice in Concord comes down to 1800 Sutter Street and 300 Baker Avenue, the 2 buildings behind all 19 units. With the largest available suite at 230 m² and the median at 58 m², both addresses are aimed at small and mid-sized occupiers, so signage, parking allocation and after-hours access are worth raising at the first viewing rather than once a shortlist has formed.
