Can an HOA splash pad have age restrictions?

HOA boards have authority to set splash pad age rules under their general rule-making powers as long as restrictions are reasonable, posted, and uniformly applied. Common rules: children under 12 must be supervised by an adult; children not yet potty trained must wear approved swim diapers; adults-only swim hours (early morning or late evening) on a posted schedule. The Fair Housing Act prohibits familial-status discrimination but allows reasonable safety-based restrictions. Banning all children outright would likely violate the FHA in non-55+ communities; limiting hours or requiring supervision typically does not. 55+ age-restricted communities have broader latitude under the Housing for Older Persons Act. Document the safety rationale in writing — capacity limits, supervision ratios, equipment scaled for small children — to defend against challenges. Apply rules consistently regardless of family demographics.
