Weapons prohibited in certain places — Local laws and ordinances — Exceptions — Penalty.
(1) It is unlawful for any person to enter the following places when he or she knowingly possesses or knowingly has under his or her control a weapon:
(a) The restricted access areas of a
jail, or of a law enforcement facility, or any place used for the confinement of a person (i) arrested for, charged with, or convicted of an offense, (ii) held for extradition or as a material witness, or (iii) otherwise confined pursuant to an order of a court, except an order under chapter 13.32A or 13.34 RCW. Restricted access areas
do not include common areas of egress or ingress open to the general public;
(b) Those areas in any building which are used in connection with
court proceedings, including courtrooms, jury rooms, judge's chambers, offices and areas used to conduct court business, waiting areas, and corridors adjacent to areas used in connection with court proceedings. The restricted areas do not include common areas of ingress and egress to the building that is used in connection with court proceedings, when it is possible to protect court areas without restricting ingress and egress to the building. The restricted areas shall be the minimum necessary to fulfill the objective of this subsection (1)(b).
In addition, the local legislative authority shall provide either a stationary locked box sufficient in size for pistols and key to a weapon owner for weapon storage, or shall designate an official to receive weapons for safekeeping, during the owner's visit to restricted areas of the building. The locked box or designated official shall be located within the same building used in connection with court proceedings. The local legislative authority shall be liable for any negligence causing damage to or loss of a weapon either placed in a locked box or left with an official during the owner's visit to restricted areas of the building.
The local judicial authority shall designate and clearly mark those areas where weapons are prohibited, and shall post notices at each entrance to the building of the prohibition against weapons in the restricted areas;
(c) The restricted access areas of a
public mental health facility certified by the department of social and health services for inpatient hospital care and state institutions for the care of the mentally ill, excluding those facilities solely for evaluation and treatment. Restricted access areas
do not include common areas of egress and ingress open to the general public;
(d) That portion of an establishment classified by the state liquor control board as
off-limits to persons under twenty-one years of age; or
(e) The
restricted access areas of a commercial service airport designated in the airport security plan approved by the federal transportation security administration, including passenger screening checkpoints at or beyond the point at which a passenger initiates the screening process. These areas
do not include airport drives, general parking areas and walkways, and shops and areas of the terminal that are outside the screening checkpoints and that are normally open to unscreened passengers or visitors to the airport. Any restricted access area shall be clearly indicated by prominent signs indicating that firearms and other weapons are prohibited in the area.

So it is not illegal to conceal carry into a hospital in Washington state, regardless of the signage on the doors, as long as you don't enter the loony ward. If you get caught, they'll toss you out and you won't exactly be welcomed back with open arms, however.
