No one was injured.
The fire happened in a wooded portion right behind an apartment complex at 6600 Lancaster around 10 a.m. Wednesday.
Although firefighters quickly put out the fire, the battalion chief said the apartment could have caught on fire if the winds were blowing any stronger.
Firefighters had to cut some tree branches that were still smoldering. The ground below was littered with the remnants of spent bottle rockets.
Setting off fireworks inside city limits is illegal.
No one has been cited in this incident.
First responders have said they are concerned the high temperatures coupled with drought conditions makes for a dangerous combination when it comes to people playing with fireworks.
