Notice must be posted at reasonable intervals around the perimeter of any location where weapons are prohibited to alert the public that firearms are prohibited at the location. 
 
Open Carry of Firearms and Weapons.  Washington law does not generally prohibit the open carry of firearms in public locations where the possession of weapons is not otherwise prohibited, except with respect to permitted demonstrations and state capitol campus grounds and legislative facilities.
 
It is a gross misdemeanor offense for a person to knowingly open carry a firearm or other weapon while knowingly being in the following locations:  on the west state capitol campus grounds; in any buildings on the state capitol grounds; in any state legislative office; or at any location of a public legislative hearing or meeting during the hearing or meeting, subject to various exemptions.  A violation is a gross misdemeanor offense. 

Restrictions on the carrying and possession of firearms and other weapons are established for areas used in connection with meetings of local government governing bodies and school district boards of directors, and for certain election-related facilities.
 
School Board Meetings.  A person is prohibited from knowingly carrying or possessing firearms or other weapons in areas of facilities while being used for official meetings of a school district board of directors.  A violation is a gross misdemeanor offense.  A person who violates this restriction must have their concealed pistol license (CPL), if any, revoked for three years, and is prohibited from applying for a CPL for three years from the date of conviction.
 
There are various exemptions to this prohibition including for law enforcement officers; any person engaged in military, law enforcement, or school district security activities; and any CPL holder while picking up or dropping off a student.
 
A school district board of directors must post signs providing notice of the restrictions on possession of firearms and other weapons at facilities being used for meetings of the school district board of directors.

Exemptions to the prohibition are provided for federal, state, and local law enforcement officers and personnel when carrying a firearm or weapon in conformance with their employing agency's policy, and members of the armed forces of the United States or the State of Washington when carrying a firearm or other weapon in the discharge of official duty or traveling to or from official duty. These prohibitions do not apply to the lawful concealed carry of a firearm by a person who has a valid CPL.
 
Cities, towns, counties, and other municipalities must post signs at locations where firearms and weapons are restricted to provide notice of the restrictions.
