Final answer:
An acceptable form of square footage disclosure is not Seller measurements. Building plans and the Assessor's office are acceptable forms of square footage disclosure.
Step-by-step explanation:
An acceptable form of square footage disclosure is not Seller measurements because they may be inaccurate or misleading. The correct options for square footage disclosures include Building plans, which provide information on the size and height of buildings, and the Assessor's office, which determines the official measurement for property tax purposes.
