Palo Alto vs. Sunnyvale: Trains, Utilities, Taxes and the Market

Palo Alto and Sunnyvale are both in Santa Clara County, with Mountain View between them, and buyers often weigh one against the other. They differ in who supplies your power, which trains stop nearby, what you’d pay at closing, how many Eichler tracts each has and, by a wide margin, price. Here’s the comparison, with a live-market snapshot from our City Match-Up.

The basics

• Caltrain. Each has two stations: Palo Alto (University Avenue) and California Avenue in Palo Alto; Sunnyvale and Lawrence in Sunnyvale. See Homes Near Caltrain.
• Light rail. VTA light rail serves Sunnyvale; it doesn’t serve Palo Alto. See Homes Near VTA Light Rail.
• Electricity. Palo Alto runs its own utility, which also provides gas, water, wastewater collection and fiber. Sunnyvale gets power from Silicon Valley Clean Energy, delivered by PG&E.
• School districts. Palo Alto is in the Palo Alto Unified School District. Sunnyvale is split among several districts, including the Sunnyvale School District, the Cupertino Union School District, Santa Clara Unified and the Fremont Union High School District. Check the district’s boundary lookup for any address.
• Downtowns. Palo Alto’s University Avenue and California Avenue and Sunnyvale’s Historic Murphy Avenue are each a short walk from a Caltrain station. See Homes Near Downtown.

At closing

Palo Alto adds a city transfer tax of $3.30 per $1,000 to the county’s $1.10; Sunnyvale adds none. On a $2 million sale that’s $8,800 in Palo Alto and $2,200 in Sunnyvale. See our transfer tax guide.
