Telecommuters are a relatively large percentage of the workforce: 8.04% of people work from home. While this number may seem small overall, as a fraction of the total workforce it is high relative to the nation. These workers are often telecommuters who work in knowledge-based, white-collar professions. For example, Silicon Valley has large numbers of people who telecommute. Other at-home workers may be self-employed people who operate small businesses out of their homes.

One of the nice things about Vallejo is that it is nautical, which means that parts of it are somewhat historic and touch the ocean or tidal bodies of water, such as inlets and bays. Because of this, visitors and locals will often go to these areas to take in the scenery or to enjoy waterfront activities.

One downside of living in Vallejo, however, is that residents on average have to contend with a long commute, spending on average 34.79 minutes every day commuting to work.

Although the majority of commuting trips in the city are by private automobile, Vallejo is somewhat unusual for a city of its size for having a substantial number of people who use public transportation. For a lot of people, a ferryboat helps to get to and from their jobs every morning, which benefits everyone in the Vallejo area by reducing both traffic and air pollution.
