What to Know About Commercial Wood Doors in Duluth

You walk into the lobby of your Duluth building on a Tuesday morning. A fire inspector is waiting by the main door, clipboard in hand, asking for the annual fire door inspection report. You don’t have one. Worse—the beautiful wood door you installed last year to match the building’s historic charm isn’t fire rated. Now you’re facing a corrective order, a fine, and the hassle of finding a replacement that won’t ruin the aesthetic.

If this sounds familiar—or if you’re planning a renovation and want to avoid it—you’re in the right place. Commercial wood doors are still a smart choice for many Duluth properties, but they come with strict requirements that differ from residential doors. This guide covers the types, costs, Minnesota code requirements, and Duluth-specific challenges so you can make an informed decision without surprises.
