Can multiple HOAs share one splash pad?

Shared amenities across multiple HOAs are common in large master-planned developments where individual neighborhoods (sub-associations) connect to a master association. The master holds title to common amenities like splash pads, pools, fitness centers, and parks. Funding flows from sub-associations to the master through a recorded cost-sharing formula based on home count, lot size, or assessed value. Voting on amenity decisions usually pools sub-association votes weighted by contribution. The master declaration must spell out access rules (whether all sub-associations get equal use, peak-hour scheduling, guest limits) to prevent disputes. Key risks: one sub-association feeling underrepresented, mismatched maintenance standards, and timing of capital contributions. Always have the master and sub declarations reviewed by an HOA attorney before joining or financing improvements. Smaller HOAs occasionally enter cross-easement agreements to share an amenity without a master structure.
