Typically the term "condominium" is used when a unit smaller than 1,500 square feet is part of a planned unit development which is part of a homeowners association (HOA). If your home falls within the above criteria, it is technically a condominium.The term "condominium" is also a term of art in the real estate realm. If you do not want to use the term "condominium" then I would not use it. However, if your unit is actually part of a HOA and a master development with condominiums, it will continue to be referred to as a "condominium".
