Maryland Code, Real Property § 11-129

(a) In the case of a condominium situated wholly outside of this State, being promoted and having a sales office within the State, an application for registration or proposed public offering statement filed with the Secretary of State which has been approved by an agency in the state where the condominium is located and substantially complies with the requirements of this title may not be rejected by the Secretary on the grounds of noncompliance with any different or additional requirements imposed by this title. However, the Secretary may require additional documents or information in particular cases to assure adequate and accurate disclosure to prospective purchasers.
