New Jersey Statutes Title 45. Professions and Occupations 45 § 22A-48.1

a. A homeowners' association formed to manage the elements of property owned in common by all members of a community, whether it be an association managing a condominium, a private community, including retirement communities, or a cooperative housing development, shall not adopt or enforce a rule or bylaw limiting or prohibiting the display of the flag of the United States of America or yellow ribbons and signs supporting United States troops, or charge a fee for any such display, except as provided in subsection b. of this section. Any such rule or bylaw adopted by a homeowners' association in violation of this section shall be null and void.

b. A homeowners' association may direct removal of an American flag or yellow ribbons and signs supporting United States troops when the display threatens public safety, restricts necessary maintenance activities, interferes with the property rights of another, or is conducted in a manner inconsistent with the rules and customs deemed the proper manner to display the flag, such as the federal flag Code, 4 U.S.C. s.1 et seq., or any other applicable law or guideline.
