From the city of Dublin:
Safe and Sane Fireworks are allowed to be sold in the City of Dublin each year, beginning at noon on June 28 and ending at noon on July 5, by non-profit organizations who meet all of the requirements set forth in the Dublin Municipal Code Chapter 5.24.
Each year, non-profit organizations interested in having a booth must fill out a current fireworks packet and submit the necessary documents. The fireworks application link is made available in March of each year to qualifying non-profits who have previously submitted an application. A drawing is held in early May if needed to determine which non-profit organizations will receive a fireworks booth. A representative from each organization must be present in order to qualify for a booth.
The City of Dublin has four designated parks where the use of Safe and Sane Fireworks is permitted between the hours of 10:00 a.m. and 10:00 p.m. on July 4th, only. No fireworks of any type (including Safe and Sane) are permitted at Dublin multi-housing units or at any undesignated Dublin Park, other City facility, or school.
The City of Dublin has a zero-tolerance policy for illegal fireworks. Those caught using illegal fireworks will be fined the maximum penalties allowed by State law and could face jail time.
