The enclave is officially open to the public during normal working and visiting hours and for approved public events. The enclave is closed to the public at all other times, and the Director may also officially close all or part of the enclave, or any building, in emergency situations and at other times the Director deems necessary to ensure the orderly conduct of Government business. When all or part of the enclave is closed to the public, admission is restricted to employees and other authorized persons who may be required to display Government credentials or other identification when requested by a police officer and may be required to sign a register. The living quarters and adjacent areas are not open to the public but are open at all times to occupants and their visitors and business invitees, unless otherwise closed by the Director.

(a) Hobbies and sports. A person may undertake hobbies and sports only in designated areas or as approved by the Director.

(b) Pets and other animals. A person may not bring on the enclave any cat, dog, or other animal except for authorized purposes. This prohibition does not apply to domestic pets at living quarters or to the exercise of these pets under leash or other appropriate restraints. The use of a service animal by a person with a disability to assist that person is authorized.

(c) Photography. A person may take photographs, films or audiovisuals, for personal or news purposes on the grounds of the enclave or in entrances, lobbies, foyers, corridors, and auditoriums in use for public meetings, except when contrary to security regulations or Department of Health and Human Services policies, or where prohibited by appropriate signs.

A person may not possess, sell, consume, or use alcohol or other intoxicating beverages, except in connection with official duties, as part of authorized research, or as otherwise authorized by the Director, or, in the case of possession, consumption or use only, in living quarters. (The sale, consumption, use, or possession of narcotics and other controlled substances is prohibited and shall be governed by the Controlled Substances Act (21 U.S.C. 841-845); driving under the influence of an alcoholic beverage, drug or controlled substance is prohibited and shall be governed by the Maryland Transportation Code Annotated section 21-902.)

No person other than a specifically authorized police officer shall possess firearms, explosives, or other dangerous or deadly weapons or dangerous materials intended to be used as weapons either openly or concealed. Upon written request, the Director may permit possession in living quarters of antique firearms held for collection purposes, if the Director finds that the collection does not present any risk of harm.

A person may not remove Federal property from the enclave or any building on the enclave without a property pass, signed by an authorized property custodian, which specifically describes the items to be removed. In an emergency, or when the property custodian is not available, a police officer may approve removal of Federal property if, after consulting with the administrative officer or other appropriate official, the police officer is authorized by the official to do so. Privately-owned property, other than that ordinarily carried on one's person, may be removed only under this property pass procedure, or upon properly establishing ownership of the property to a police officer.

Packages, briefcases, or other containers brought within the enclave are subject to inspection while on, or being removed from, the enclave.

L. 95-454).

This provision shall not apply to authorized lessees and their agents and employees with regard to space leased for commercial, cultural, educational, or recreational purposes, under the Public Buildings Cooperative Use Act of 1976 (40 U.S.C. 490(A)(16)).
