Open burning of yard waste, leaves, and refuse is prohibited in Detroit. Michigan's Part 115 solid-waste law bans open burning of yard waste in every municipality over 7,500 population, and Detroit's Fire Prevention and Protection Code (Chapter 19, Division 5) reinforces the ban. Only contained recreational campfires burning clean wood for cooking or recreation are allowed; open piles, leaf burning, and burning of construction debris are not.

Open Burning and Outdoor Fire Activities are covered in Division 5 of the chapter. A 'campfire' is defined as an outdoor fire in a fire pit for recreation or cooking โ€” not for waste disposal โ€” and may only burn clean wood.

General Permit Tips

When do you typically need a permit?

Most cities require permits for structural work, including fences over a certain height, pools, ADUs, and sheds above a size threshold. Even projects that seem minor can trigger permit requirements, so it is always best to check first.

How to apply for a building permit

Visit your local building department or their website. Most jurisdictions accept online applications. You will typically need a site plan, project description, and may need contractor information. Processing times vary from same-day for simple projects to several weeks for larger builds.

Common permit violations to avoid

Building without a permit, exceeding approved dimensions, and ignoring setback requirements are the most common violations. Penalties can include fines, required removal of the structure, and complications when selling your home.
