In most places in the US, the upper limit for a driver's BAC is 0.08. However, you should check the laws of the state you're in, it could be lower than that.
If you're not driving, then there isn't really a legal limit. Some places have "public intoxication" laws, but those are for the most part concerned with behavior rather than actual blood alcohol measurements; as long as you're not causing problems, the police are unlikely to care how drunk you are.
Legal limit under age of 21 in California
The legal blood alcohol concentration (BAC) limit for driving is typically 0.08% in most states in the United States. Driving with a BAC above this limit is illegal and can result in DUI (driving under the influence) charges. Commercial drivers and individuals under the legal drinking age may have lower BAC limits.
In most states, if you are under 21, the legal blood alcohol level is 0.2. If you are 21 or over, the legal limit is 0.8.
Any BAC over .000.
Yes, you can still be convicted of DUI even if your BAC is under 0.08 for a first offense. If your driving is impaired by alcohol or drugs to the point where you are unable to operate a vehicle safely, you can still be charged and convicted of DUI.

BAC legal driving limits are the same for minors (under 21) as for adults. The only difference is that if you are under 21, in addition to being charged with a DUI or DWI you will also be charged for underage drinking. My suggestion to you is don't drink until you are 21, and always have a sober driver. In Oregon you will be charged for DUI under 21 if you have ANY measurable amount of alcohol in your blood.
