If you feel a business is not following the rules, you can always contact your local fire marshal.

You've seen a business with two front doors to enter and leave.

Kevin Yost, from Henrietta, asked why many businesses keep one of those doors always locked. He wanted to know if that is against fire code.

Messenger Post's news partner News10NBC found several local businesses in the area that do keep one door open and lock the other.

The concern: what happens if there's a fire or an emergency evacuation, do both doors have to open?

We took that question to Scott Copp, who's with the Finger Lakes Building Officials Association.

"The building code in New York State and local fire code allow one of those doors to be closed and latched in position," Copp said.

So it is okay for a business to lock one door, but store owners must notify patrons.

"The opposing door has to have a sign that says this door will remain unlocked when this business is open," Copp said.

Our cameras found several businesses that did not have that sign, which means they could be fined if a fire marshal pays a visit.

That fine is almost always avoided. If a business is found to break code, the fire marshal will visit and give them time to correct the problem.

If you feel a business is not following the rules, you can always contact your local fire marshal.
