Whether or not a tennis court can be built at the complex where your property is located with other common properties subject to the association's rules and regulations will be determined from the recorded "covenants, conditions & restrictions" concerning the complex and any subsequent rules and regulations approved by the homeowners through a required vote.As such, you need to carefully read the recorded "covenants, conditions & restrictions" applicable to your complex and the question you ask and all subsequent rules and regulations approved by the association's members.The best way to get an answer to your question is to retain an attorney experienced with association rules and regulations to assist you and other members of the complex as to the tennis court issue.Good luck.
