Establishes "State House Flag Program"; makes appropriation.

S 1604 establishes the "State House Flag Program" through the State Capitol Joint Management Commission, allowing members of the New Jersey Legislature to request commemorative New Jersey State flags flown over the State House. The program requires the Building Management office to mail each requested flag with a certificate detailing the date flown and the recipient (individual, group, or organization). The bill appropriates funds from the General Fund to cover implementation costs for this ceremonial program. This is a procedural measure with no substantive policy changes, solely enabling symbolic recognition through flag displays.
