As we head into the Fourth of July weekend, here are some things to keep in mind.


The possession or discharge of fireworks, firecrackers or skyrockets is prohibited in the city of Boulder and Boulder County. This includes but is not limited to sparklers, snaps, bottle rockets, roman candles and smoke bombs. Violations of law are enforced under the CU Student Code of Conduct and can result in sanctions such as probation, fines or educational courses.

Fireworks not only pose a significant fire risk, but they also can cause a significant noise disruption to residential areas. Even if you don’t possess or discharge fireworks, you may be held responsible for roommates’ or guests’ violations of this ordinance. 

If you find yourself in possession of fireworks, you can turn them in to any of the local Boulder fire departments—no questions asked! The fire department will dispose of the fireworks in a responsible manner for you.

Noise ordinances

You can receive an unreasonable noise citation for any noise, music or conversation that can be heard more than 100 feet away from your residence after 11 p.m. This city of Boulder ordinance is similar to "quiet hours" in apartment buildings.

If your residence receives a warning about noise, make sure to let your roommates know. Receiving more than one warning can result in a “disruption of quiet enjoyment of the home” ticket. Many times a house will receive a formal warning, but not all roommates are aware. And remember, you can get a ticket at any time of the day for excessive and disruptive noise or any other illegal things occurring at your gathering, including underage drinking, brawling, public urination, littering or trash, etc.

Safety tips

If you choose to use alcohol or other drugs, here are a few things you should know:

  • Drink with people you know and trust, and look out for each other.
  • Eat before drinking, and continue to eat food and drink water throughout the night.
  • Set a limit before celebrating and stick to it.
  • Make a plan for how to get home safely (walking, public transportation, Uber/Lyft, etc.).
  • Drink at your own pace. Avoid trying to keep up with someone else.
  • Know how much is one serving of alcohol: 1.5 ounces of hard liquor, 5 ounces of wine and 12 ounces of beer.
  • Avoid mixing prescription drugs with alcohol. This is the most common cause of overdose.
  • Know the signs of alcohol poisoning and how to put someone in the Recovery Position.
