HOA Board

Assuming you are part of an existing HOA, the board governing documents should set forth the size of the board and the operation of the board. The bylaws (one of the governing documents) should set forth a specific number (or a range for the number of) members of the board of directors. Your property manager should be able to provide you a copy of all the governing documents. Your HOA should engage legal counsel and a competent property manager to ensure the HOA is appropriately setup and operated. If you are looking to form a common interest community (which is run by an HOA), there are a number of factors to evaluate in determining the appropriate size of a board, but a discussion of those factors and the proper way to set up a common interest community are beyond the scope of a response to this forum question, but can be answered by a competent real estate / common interest community attorney.
