Only Mountain View publishes a complete public tennis inventory — everywhere else, verify before you go

A facility-level directory of 43 public tennis locations across 15 cities in Santa Clara County, Palo Alto and San Mateo County — courts, hours, fees and booking method as found in a live-web scan on 2026-08-28. Blank cells mean the detail was not found, not that it does not exist.

Before traveling: open the linked source for each facility and verify hours, tennis-specific fees, court conversions or closures, and reservation rules. Several rows rely on secondary directories or older city documents — those carry an orange caveat flag.

What the matrix cannot say alone

Mountain View is the model listing: its official tennis page states court count, hours and access for all five city facilities — Cuesta Tennis Center (12 courts, 6 a.m.–11 p.m., walk-on and advance online reservation) plus four walk-up parks. mountainview.gov

Cupertino's "Friday, 9 a.m." is a senior drop-in program session time taken from a Senior Center newsletter — it is not the park's opening hours. cupertino.gov

San Mateo's $5 drop-in fee appears tied to a Friday pickleball session and comes from a secondary pickleball directory, not the city itself. pickleballplusapp.com

Santa Clara's phone-and-online booking timeline comes from an older reopening notice; the current rate source states $12/hr resident and $14/hr nonresident at the Tennis Center and Lick Mill Park. santaclaraca.gov

Method: broad live-web scan as of 2026-08-28, not a guaranteed legal inventory. 43 rows, one per discovered public tennis facility, ordered by city then facility. "South Bay and Peninsula" operationalized as Santa Clara County plus Palo Alto and San Mateo County. Court counts are as stated by the source; blank cells mean the detail was not found in the sources located — not that there are zero courts or no fee. Some municipalities publish no consolidated inventory; some rows rely on secondary directories or older city documents and are flagged. No aggregate totals are computed from these rows.
