The following cities have laws against open carry by non-CHL holders: Portland, Beaverton, Salem, Oregon City, Tigard, and Independance. Cities and counties may also pass park carry bans (as this is considered a "public place" that may be regulated under ORS 166.173), however again this cannot be enforced against CHL holders.Portland and Oregon City are off limits -- just off the top of my head.
State Parks, Federal Parks not lawful. These all seem to have signs posted near the gates. Stop and read what the sign says.
Porltand metro area will be pretty uptight about OC, but outlying areas don't look twice unless you're being "intimidating" . . . But then I'm nearly 60, look middle class and have a nice Galco rig that matches the belt and coordinates with with I'm wearing.
Most just assume I'm some sort of LEO.
Some stores get anxious . . . and it seems like it's the ones that sell ammo and sporting goods, the same ones that escort you and your new rifle to the door before you get to hold it.
Burger King, StarBucks, McDonalds seem to get anxious, unless you're really low key about OC. If you look like you're "hunting" and in a rural area it's fine. If you're in the suburbs, they'll call the police -- or at least ask: "You have a permit for that gun?"
(No permit required to OC in Oregon.)
See: Oregon Revised Statute 166.173, which I will post in entirety:
166.173 Authority of city or county to regulate possession of loaded firearms in public places. (1) A city or county may adopt ordinances to regulate, restrict or prohibit the possession of loaded firearms in public places as defined in ORS 161.015.
(2) Ordinances adopted under subsection (1) of this section do not apply to or affect:
(a) A law enforcement officer in the performance of official duty.
(b) A member of the military in the performance of official duty.
(c) A person licensed to carry a concealed handgun.
(d) A person authorized to possess a loaded firearm while in or on a public building or court facility under ORS 166.370. [1995 s.s. c.1 §4; 1999 c.782 §8]
The law on this subject is clear as crystal: It states that it does not apply to a person who happens to be licensed to carry a concealed handgun. Before the semantic wordgames get played on "well it says carry a concealed handgun and therefor it must be concealed", the reason why "concealed handgun" is mentioned is only because open carry is not generally regulated and is not licensed.
You notice in there a lack of an "armed security" exemption to the locally passed laws. The Portland City Council Code 14A.60.010, which enforces the provisions of ORS 166.173 as allowable, includes several exemptions beyond the state law (which is allowed, as Portland may pass as many additional exemptions as it wants because it's their law and their option), which includes armed security on duty at an FDIC insured banking institution.
Armed Security Officers, who are openly carrying their duty weapons in Portland without CHL's at places other than an FDIC covered institution are in violation of the Portland ordinance and would find no protection in state law or in their DPSST licensing. They must comply with the Portland ordinance by another exemption either in the city code (which includes the issuance of a special license by the City Police Chief which to my understanding is never issued) or in the state code, which has a CHL exemption (the Portland code also has this exemption but I was trying to illustrate a point with the security licensing).
Every armed security officer job I've ever seen posted in the Portland metro area require a CHL for this reason. As for as ORS 166.173 is concerned, armed security officers are nothing more than private civilians. Some cities may excercise the option to allow all DPSST armed security on duty to carry, and to and from duty (Beaverton has this exemption), however the cities are not required to pass this exemption.
As for state parks:
Specifically OAR 736-010-0040. This used to ban possession of firearms but Oregon Firearms Federation challenged the Parks and Recreation Department under preemption. Parks and Rec folded and rewrote the rules. If there are any state park signs that prohibit firearms, please report them here and I'll gladly make the appropriate phone calls to get them taken down.
