Sheese, does anyone here actually read the law?
18 USC 930
(g)(1)The term “Federal facility” means a building or part thereof owned or leased by the Federal Government, where Federal employees are regularly present for the purpose of performing their official duties.
For 'normal' federal buildings not covered under a specific CFR (like the VA and Post Offices, for example), there is no restriction as to "grounds" (parking lots).
(g)(3)The term “Federal court facility” means the courtroom, judges’ chambers, witness rooms, jury deliberation rooms, attorney conference rooms, prisoner holding cells, offices of the court clerks, the United States attorney, and the United States marshal, probation and parole offices, and adjoining corridors of any court of the United States.
No mention of 'grounds' either.
But then they throw this one in there, which I believe is unconstitutional. How would a reasonable person know if there was such 'rules' or 'orders'?
(f) Nothing in this section limits the power of a court of the United States to punish for contempt or to promulgate rules or orders regulating, restricting, or prohibiting the possession of weapons within any building housing such court or any of its proceedings, or upon any grounds appurtenant to such building
