115 counted public courts across 11 cities — San Jose alone holds 49 of them

A best-effort live-web inventory of 41 facility listings (37 distinct sites after merging four likely name variants) of publicly accessible tennis courts across San Mateo and Santa Clara counties, checked 2026-08-29. Court counts are known for 31 sites; six sites list no count. Blank fees, hours, or booking cells mean the source did not state them — not that access is free or unrestricted.

This is not a guaranteed exhaustive municipal asset register: several cities did not expose indexable details. Private clubs, hotels, apartments, member-only courts, and pickleball-only sites were excluded; school courts appear only under explicit city joint-use.

San Jose lists 49 courts across ten parks — 43% of every counted court in the inventory — and every one is marked free, though none states hours or a booking method. app.tenniscity.org

Redwood City publishes the most complete picture: six parks, 14 courts, all free, all open dawn to dusk with lighted courts until 10pm, all first come, first served. redwoodcity.org

Menlo Park is the only city with published hourly rates — $10/hour resident, $15/hour non-resident, $25/hour commercial at four parks — while its La Entrada School courts are explicitly free. menlopark.gov

Burlingame is the only city running an online reservation system across its three parks; Washington Park keeps court #1 drop-in only and unreservable. burlingame.org

Four facilities appear under two name variants each — Ray Park, Washington Park, Marlin Park (Redwood City) and Thamien Park (Santa Clara). Their court counts are counted once, not summed. tennispickleballcalifornia.com

Private, member-only, hotel, apartment and pickleball-only sites were excluded. Operator names are shown in the tooltip and omitted from the table for space.
