No, it still applies.

The Third Amendment states that “No Soldier shall, in time of peace be quartered in any house, without the consent of the Owner, nor in time of war, but in a manner to be prescribed by law” meaning that the national guard or any other military force can’t just force themselves into private establishments for housing without permission, like how they forced hotels to accommodate them. And, thanks to the Youngstown Sheet & Tube Co. v. Sawyer (1952) case, Justice Robert H. Jackson is quoted saying that “seizure of needed military housing must be authorized by Congress.”

Guess what they didn’t do?

Go through Congress.
