Fireworks Laws and Safety

Enjoy a Safe 4th of July

Union City welcomes your participation in providing a safe 4th of July for all Union City residents.  Please practice basic safety procedures in compliance with all laws.

  • Only “Safe and Sane” fireworks are allowed in the City of Union City. “Safe and Sane” fireworks” means those fireworks defined and classified in Sections 12529 and 12562 of the CA Health and Safety Code.
  • “Safe and Sane” fireworks may be deployed between 8:00 AM to 10:00 PM, July 1 – 4 on your private property. 
  • If you intend to use "Safe and Sane" fireworks on property other than your own, you must have written approval from the property owner. 
  • Deploy fireworks at least ten feet away from any dwelling or structure.
  • Use fireworks under adult supervision.
  • Fireworks are not allowed east of Mission Boulevard, in City parks, on school property, and on City streets.
  • Do not deploy illegal fireworks alongside “Safe and Sane” fireworks.  Fireworks that explode or go up in the air are illegal. This includes firecrackers, bottle rockets, aerial shells and mortars.
  • Property owners can be fined up to $1,000 if illegal fireworks are deployed from their property. 
  • Individuals possessing or deploying illegal fireworks from any location may be fined up to $1,000.

Let’s work together to stop the discharge of illegal fireworks.  To report individuals using, or selling illegal fireworks, call the non-emergency police dispatch line at (510) 471-1365.

Fireworks may be harmful if they are not used safely and responsibly.

  • 19,500 reported fires in the US each year stem from fireworks. *
  • It is suggested that you keep fireworks out of the hands of children and teens under the age of 15 – as they account for one-third (36%) of firework injuries. *
  • It is advised that you keep pets inside when fireworks are going off to prevent anxiety and dispose of them quickly to avoid your pet ingesting used fireworks.

Proper Disposal of Fireworks

  • Safely dispose of spent (unused) fireworks by submerging them in a bucket of water overnight before double-bagging the spent fireworks and placing this bag in the landfill cart (not the recycle or compost carts). 
  • Unused fireworks can be stored in a dry, cool place away from electrical appliances. Safely and responsibly disposed unused fireworks at the Hayward Household Hazardous Waste Facility by appointment for no additional cost. Conveniently schedule your drop-off appointment by visiting StopWaste.org/HHW and clicking on the "Make Appointment for Hayward" button. Unused fireworks are prohibited in the recycle, compost, and landfill carts.
