When Michigan Lets You Light Fireworks (and When Your City Can Say No)

Here’s the part people get wrong: your city really can outlaw backyard mortars — just not on the days that matter. Since 2018, a Michigan town can pass an ordinance banning consumer fireworks the other 350-some days of the year. But on a short list of holiday-adjacent days, the state ties its hands. On those days a local ordinance can only push the hours around; it can’t shut the fireworks down.

The protected days, as the law stands now: June 29 through July 4, and again on July 5 when it lands on a Friday or Saturday. The Saturday and Sunday right before Memorial Day. The Saturday and Sunday right before Labor Day. And New Year’s Eve into New Year’s morning. On each of those, you’re clear from 11 a.m. until 11:45 p.m. — New Year’s runs until 1 a.m. That’s roughly a dozen days a year, down from the old law that gave you the day before, of, and after every national holiday. The 2018 amendment quietly cut that list.

So the real question isn’t “is it legal in Michigan” — it’s legal everywhere. The question is what your township or city did with the power the state handed back. Detroit, Grand Rapids, and plenty of smaller places have ordinances on the books restricting the off-days and the late hours. Look up your own before you assume the guy two houses down knows what he’s doing.

A few things the state law nails down no matter where you live. You can’t set them off on someone else’s property, or public, school, or church grounds, without permission. No lighting them while drunk or high. Nobody under 18 is supposed to be buying them. And if your town does write an ordinance, the most it can fine you is $1,000 a pop — half of which goes to the local police.

None of this is legal advice, and a cranky neighbor with a phone can still ruin your Fourth. But now you know which nights are yours.
