Where to play
Mark Green Sports Center
Mixed levelsMark Green Sports Center is a city-run multi-sport gym with two indoor wood-floor pickleball courts — permanent lines, portable nets, shared with basketball, volleyball, badminton, and table tennis. Open-gym pickleball runs Mon/Wed/Fri 6am–3pm in Gym B for ages 16+; the broader Sports Center is open weekdays 6am–9pm and weekends 7am–3pm. Pricing is unresolved: expect a $10 resident / $15 non-resident daily drop-in, though you may see a flat $5 day pass quoted for pickleball specifically — worth confirming before you go. This is genuinely the only public pickleball venue in Union City; residents are pushing the city for dedicated outdoor courts, and no other city facility offers pickleball access.
- Walk-up only — no reservation system or online booking.
- You may see listings claiming additional Union City pickleball courts (one as many as 16); every one we checked is actually in a neighboring city (Hayward, Fremont, Campbell, San Francisco, San Bruno) — a "near you" radius search mislabeling results by city, not real Union City venues.
- Elite Badminton Center in Union City is badminton-only — no pickleball, despite sometimes surfacing in searches.
- Pricing is unresolved: expect $10 resident / $15 non-resident daily drop-in, though you may see a flat $5 day pass quoted. Confirm before you go.
