What CSYBA published (homepage notice)
CSYBA states that beginning in Fall 2026 and heading into Spring 2027, based on input from over 70 participating communities, house league rules were adjusted so that for all levels, USA Baseball and USSSA Baseball bats will be allowed.

Where we’re being careful
- Some older division pages (e.g. a Pony rules page) still describe tighter limits — including language that USSSA 1.15 bats are NOT ALLOWED and only USA, BBCOR, and wood are permitted. That may be outdated relative to the homepage notice, or it may apply to a specific division/season.
- Colt / older divisions have historically pointed toward BBCOR for aluminum.
- We have not independently confirmed every 2026–2027 division PDF. If your team’s packet conflicts with the homepage, follow the packet and ask the commissioner.
Not confirmed for every CSYBA division: Treat the homepage “USA + USSSA for all levels” note as the current house-league direction for Fall 2026 / Spring 2027, and verify with your town’s CSYBA contact before buying a USSSA-only bat for house play.
