A relatively large number of people in Mammoth Lakes telecommute to their jobs. Overall, about 12.82% of the workforce works from home. While this may seem like a small number, as a fraction of the total workforce it ranks among the highest in the country.

Other at-home workers may be self-employed people who operate small businesses out of their homes.

During the low season, year-round residents will notice that the city is a substantially quieter place to live.
