Mark 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.
