The Menlo Park list runs to 10 office lots, all of them at 101 Jefferson Drive, so the choice in this city is between suites in one building rather than between districts. Menlo Park sits on the San Francisco Peninsula, a corridor where office availability is chronically thin, and a single address carrying 10 open lots is a wider block of choice than the headline count suggests.
Suite sizes in Menlo Park span 5 m² to 520 m² with a median of 190 m², covering three very different occupiers: a name-plate office at the small end, a 15- to 20-person product team at the 190 m² median, and a 520 m² floor for a company of around 40. Menlo Park is venture and technology territory where teams grow in steps of a few people, and a full stack of sizes inside one building is what lets a tenant move up without changing address.
Anyone shortlisting Menlo Park should treat the 190 m² median as the market's centre of gravity: units below it are usually taken quickly, while 520 m² is the hard ceiling of the current list, with nothing larger at this address. Because all 10 Menlo Park lots share one building, timing outweighs geography — fix a start date, check which suites are free around it, and remember that the alternative to a taken lot is another lot in the same lobby, not another part of the city.
