Can Bartenders Drink on the Job in Washington State?

Washington bans bartenders from drinking on the job under WAC 314-11-015. See the exact rule, the narrow exceptions, and what MAST permit holders risk.
Aug 30
Quick Answer: Washington requires a MAST permit — by law, servers, bartenders and managers at on-premises licensed establishments must obtain one within 60 days of hire. A Class 12 permit is for workers 21 and older; Class 13 covers ages 18–20. Permits are valid for five years and are not renewable — you take a new course. Training must come through a WSLCB-licensed provider; Certification Experts offers Washington training through an approved third-party route.

Picture a Friday night in a Ballard taproom. The rail is three deep, and a regular slides a twenty across the bar and tells the bartender to pour one for herself. In plenty of states, what happens next is a judgment call shaped by house policy and local custom. In Washington, it is not. The state wrote its answer directly into the administrative code, and the answer is no: bartenders and servers may not drink while they are working. This guide walks through the exact regulation, the permit system behind it, what a violation costs a server personally, and how Washington compares to its neighbors on both sides.

The Short Answer in a MAST-Permit State

Washington runs one of the most structured alcohol service systems in the country. It operates a mandatory statewide training program, issues individual permits to every bartender and server, and, unlike many states, addresses on-duty drinking directly in its regulations. WAC 314-11-015 lists the responsibilities of liquor licensees and their employees, and among the prohibited conduct is this: licensees and employees may not consume liquor of any kind while working on the licensed premises. A shift drink, a celebratory toast with a regular, a taste of the new IPA you just tapped: while you are on the clock at a licensed establishment, all of it is off limits unless you fall inside one of a few narrow exceptions covered below.
The same regulation also makes the stakes collective. In the words of the rule, "Any violations committed or permitted by employees will be treated by the board as violations committed or permitted by the licensee." That is why Washington bars tend to police the rule themselves: your shift drink is their license problem.

The Liquor and Cannabis Board and the MAST Program

Alcohol in Washington is regulated by the Washington State Liquor and Cannabis Board, usually shortened to LCB or WSLCB. The board licenses establishments, enforces the state liquor code, and administers the Mandatory Alcohol Server Training program, better known as MAST. The drinking age is 21, as it is everywhere in the United States, but Washington layers a personal permit system on top of it.
The LCB states that MAST "is required by law for people who serve, mix, sell, and supervise the sale of alcohol for on-premises consumption." The board also extends the requirement to people conducting alcohol tastings at off-premises licensed businesses and to employees filling growlers at grocery stores. Under WAC 314-17-030, a licensee "must ensure that any person who engages in the sale or service of liquor for on-premises consumption, or who supervises such activities, has a current and valid class 12 or 13 permit within 60 calendar days of the date of hire." The LCB warns that anyone without the required permit inside that timeline "may get a criminal citation with a maximum $500 monetary penalty, up to 90 days in jail, or both."
Permits run five years. WAC 314-17-020 provides that class 12 and 13 permits are valid for five years and expire on the first day of the month five years after the month you passed the standardized exam, and that "A permit holder must retake a class 12 or 13 training course and pass the standardized exam to obtain a subsequent class 12 or 13 permit." The LCB puts it more bluntly: the permit "is good for five years. It is not renewable." There is no grace period once it expires, and the board recommends taking a new course about 45 days before your current permit runs out so you are never working unpermitted.
Important, and please read this before you buy anything. Washington mandates MAST training, and the permit can only come from a course provider certified by the LCB. Certification Experts is not an LCB-certified MAST provider, and our Washington course is not a state-approved MAST course. It will not produce a class 12 or class 13 permit and it does not satisfy Washington's training mandate. What it does is teach the underlying material — checking identification, spotting the signs of intoxication, refusing a sale, and handling the situations that get servers in trouble. Use it as background reading or a refresher if that is useful to you, then get your actual permit from a provider on the LCB's certified list at lcb.wa.gov/mastrvp/providers_trainers. Our Washington alcohol awareness resources are written to complement that state-certified course, never to replace it.

The On-Duty Drinking Rule in the WAC

The rule itself lives in WAC 314-11-015(4)(d): licensees and employees may not consume liquor of any kind while working on the licensed premises. Two phrases in that sentence carry most of the legal weight, and they are where the nuance lives.
First, while working. The prohibition attaches to your working time, not to the building. Nothing in the section bars an off-duty employee from being served as an ordinary customer at the bar where they work, although many employers set stricter house policies and some insurers demand them. Second, liquor of any kind. The regulation does not distinguish between a shot of whiskey and a half-ounce taste from a new keg. Quality-control sips, staff tastings during service, and drinks bought for you by guests all count as consumption.
The same subsection adds a related rule that follows you even off the clock: licensees and employees may not "be disorderly or apparently intoxicated on the licensed premises." So the off-duty beer is lawful, but showing visible signs of impairment at your own workplace is not.
The exceptions are narrow and written for specific situations. Entertainers may drink while performing under tight conditions: alcohol service must be monitored by MAST-permitted servers, drinks must be served in unlabeled containers, the performers may not advertise alcohol brands or promote drink specials, and if any member of the group is under 21, no member of the group may consume alcohol while performing.
The producer exceptions are separate from each other, and the details differ more than most summaries admit. For beer, WAC 314-11-015(4)(d)(ii) allows licensed beer manufacturers and their employees to sample beer of their own manufacture "for manufacturing, evaluating or pricing product in areas where the public is not served, so long as the licensee or employee does not become apparently intoxicated." For wine, there are two separate paths: one covers sampling for manufacturing, evaluating, or pricing product, and its condition is that the person sampling is not also engaged in serving alcohol to the public; the other covers sampling for quality control or consumer education purposes and carries no public-area restriction at all. Both wine paths still require that the person not become apparently intoxicated. In short, "away from the public" is the beer condition; "not simultaneously serving the public" is the wine condition on one path, and the consumer-education path has neither.
Notice who is missing from all of that: bartenders and servers at bars, restaurants, taverns, and clubs. If you work the rail at a retail licensee, no exception applies to you. Not a taste, not a sip, not for quality control.

Class 12 vs Class 13: Same Rule, Different Jobs

Washington issues two classes of MAST permit, and the difference determines what you can legally do behind the bar. Under WAC 314-17-015, a class 13 permit holder must be at least 18 years of age and may take orders for alcoholic beverages for on-premises consumption, deliver those beverages to customers, and open or pour beer or wine into a customer's glass — but not in an area the board has classified as off limits to anyone under 21. Class 13 does not cover mixing drinks or drawing from a dispensing device.
A class 12 permit holder must be at least 21. Class 12 covers managing an on-premises licensed facility, selling, mixing, or drawing alcoholic beverages from a dispensing device for on-premises consumption, and supervising a class 13 permit holder. A class 12 permit includes everything a class 13 permit allows. Practically speaking: if the job involves cocktails or the tap handle, it is a class 12 job.
Both classes are equally bound by the on-duty drinking prohibition, but for a permit holder under 21 the stakes double. RCW 66.44.270 makes it unlawful for a person under 21 to possess, consume, or otherwise acquire liquor, so a 19-year-old server who sneaks a drink on shift stacks a criminal statute on top of an administrative violation. If you are trying to figure out which permit your job actually requires, we break the duties down line by line in our guide to Class 12 vs Class 13 MAST permits.

Violations: What Servers Personally Risk

Here is what makes Washington different from states that only discipline the business: the LCB can suspend or revoke your individual permit, which means your ability to work. WAC 314-17-105 sets out penalties for permit holders who violate liquor laws, and the rule states that "Penalties assessed for violations within a three-year period will normally be as follows." The schedule is broken out by violation type, and the numbers are not identical across every row — which is the part most summaries get wrong.
For the catch-all "miscellaneous" row and most other categories, a first violation brings a five-day permit suspension or a $100 monetary option, a second brings ten days or $200, a third brings thirty days or $400, and a fourth brings revocation of the permit. Two rows run harsher. Selling or serving alcohol to a person under 21 keeps the same suspension lengths but raises the monetary options to $200, then $400, then $500, before revocation on the fourth. And the row covering conviction of liquor laws, driving under the influence, or a felony skips the middle of the ladder entirely: a five-day suspension or $100 on the first violation, then revocation on the second. Before you assume the mildest ladder applies, check which row your conduct actually falls under.
A suspended permit is not an abstraction. You cannot legally serve, mix, or pour until it is restored, and few employers will hold a bar shift open while you wait. The establishment faces its own consequences on a parallel track, since employee violations count against the license.
Underneath all of the administrative machinery sits the reason the rule exists. RCW 66.44.200(1) is one sentence long: "No person shall sell any liquor to any person apparently under the influence of liquor." Deciding when a guest has crossed that line is the hardest judgment call a bartender makes on a busy night, and it is precisely the judgment that a drink of your own degrades. That is the practical case against the shift drink, independent of the rulebook.

How Washington Compares to Oregon and Idaho

Cross a state line and the rules change, which regularly surprises bartenders who move between Pacific Northwest markets.
Oregon starts from the same prohibition but does not end in the same place. Under OAR 845-006-0345(3)(a), "No licensee, permittee, or agent of a licensee will consume any intoxicating substance while on-duty." Oregon also defines on duty broadly, running from the beginning of a shift involving mixing, sale, or service of alcohol, checking identification, or controlling conduct on the premises, through to the end of that shift including breaks. So a break beer out back is out in Oregon too.
But the same rule then carves out something Washington does not give retail staff. Subsection (3)(a)(B) says a person may consume tastes of alcoholic beverages as allowed by subsection (4), and subsection (4) provides that despite the on-duty ban, a person may self-serve and taste malt beverages, wine, or cider while on duty, subject to conditions: the person is not a minor, is not visibly intoxicated, tastes only between 7:00 a.m. and 2:30 a.m. the following day, takes no more than one ounce per serving and no more than six ounces total in that window, and does so for educational purposes or to test quality — to confirm the product is not flawed or deteriorated.
On the exact question this article is about, then, Washington is the stricter of the two. An Oregon permittee can legally take a measured, purposeful taste of a keg that smells off. A Washington bartender at a retail licensee cannot: WAC 314-11-015(4)(d) gives retail servers no tasting allowance at all, and the only carve-outs go to entertainers and to licensed beer and wine manufacturers sampling their own product. If a keg tastes wrong on your Washington shift, the answer is to pull it and have a manager or a supplier evaluate it, not to taste it yourself.
Idaho sits at the opposite pole. The Idaho State Police, which houses that state's Alcohol Beverage Control bureau, states plainly that "Idaho law does not prevent bartenders or servers from drinking alcohol while working," and that it is the employer's responsibility to set policy on the issue — with a recommendation that licensees consult their legal advisor and insurance provider first. Idaho likewise states that it "does not require alcohol servers to have any formal server training or certification," though some cities impose their own requirements.
Washington and Oregon treat sober service as a licensing matter with individual accountability; Idaho treats it as a management decision. If you hold a MAST permit and pick up shifts in Portland or Coeur d'Alene, assume nothing transfers. Read the local code first.

Frequently Asked Questions

Can bartenders drink after their shift in Washington State?

Yes, as far as state law goes. The WAC prohibition in 314-11-015(4)(d) applies while working, so an off-duty employee can be served like any other guest. Two limits remain: no licensee or employee may be disorderly or apparently intoxicated on the licensed premises, and many Washington employers ban post-shift drinks by policy, often at their insurer's request. Check your handbook before you order.

Can an 18-year-old bartend in Washington State?

Partially. Under WAC 314-17-015, a class 13 permit holder must be at least 18 and may take orders for alcoholic beverages, deliver them to customers, and open or pour beer or wine into a customer's glass — though not in an area the board has classified as off limits to anyone under 21. Class 13 does not cover mixing drinks or drawing from a dispensing device. Full bartending, including mixed drinks and tap pours, requires a class 12 permit, and a class 12 holder must be at least 21.

What happens if you serve alcohol without a MAST permit in Washington State?

WAC 314-17-030 gives a licensee 60 calendar days from an employee's date of hire to make sure that employee holds a current, valid class 12 or 13 permit. The LCB warns that anyone without the required permit within that timeline may receive a criminal citation carrying a maximum $500 monetary penalty, up to 90 days in jail, or both, and the employing licensee risks administrative action as well. Note that the 60-day window runs from your hire date, not from your permit's expiration: permits last five years, are not renewable, and there is no grace period once one expires, so the LCB advises taking a new course roughly 45 days before yours runs out.

Does the Certification Experts course get me a Washington MAST permit?

No. Washington requires MAST training, and the permit can only be issued through a course provider certified by the Liquor and Cannabis Board. Certification Experts is not an LCB-certified MAST provider, so our Washington course is educational and awareness training only — it does not satisfy the state mandate and it will not produce a class 12 or class 13 permit. To get your permit, choose a provider from the LCB's certified list at lcb.wa.gov/mastrvp/providers_trainers.
