Wisconsin DNR Rules for Construction and Demolition Debris

Anyone tearing into an older home, gutting a kitchen, or clearing a lot for new construction eventually runs into the same question: what am I actually allowed to do with all this debris? In Wisconsin, the answer is governed by a specific set of DNR rules, and knowing the basics before the dumpster shows up saves confusion later — and keeps your project on the right side of state regulation.

The rules that apply: NR 500–538

Construction and demolition debris in Wisconsin is regulated under Wisconsin Administrative Code chapters NR 500 through 538, administered by the Wisconsin Department of Natural Resources. It's a broad set of rules covering everything from how debris is classified to where and how it can be disposed of, and it applies statewide — from a small Appleton bathroom remodel to a large commercial demolition project.

Burning debris is not an option

This is the rule we hear the most confusion about. Burning construction and demolition debris in Wisconsin is illegal — that includes painted or treated wood, asphalt shingles, plastics, rubber, and wet rubbish, with only very limited exceptions. Burning an entire unwanted structure is also illegal in Wisconsin outside of approved fire-department training burns. Only clean, untreated wood burning can be DNR-approved or licensed under specific conditions — general debris burning on a job site is not a legal shortcut here, whatever the old rule of thumb from another state might have been.

Materials that can bypass solid-waste licensing

Certain clean materials get a practical exception. Brick, concrete, unpainted or untreated wood, clean soil, and building stone can be disposed of without going through the state's solid-waste licensing requirements — as long as placement avoids floodplains, wetlands, surface waters or critical habitat areas. This matters for renovation and landscaping projects around Appleton and the Fox Cities, where a lot of debris (old concrete patios, foundation demolition, clean fill dirt) falls squarely into this category.

What should be recycled separately

Beyond the burning and licensing rules, Wisconsin DNR guidance identifies a specific list of materials that should be separated out for recycling rather than sent straight to a landfill: metals like aluminum siding, steel and rebar; masonry including brick, concrete and asphalt; unpainted or untreated wood; drywall; carpet; vinyl siding; and PVC pipe. These are all common byproducts of a typical remodel, so it's worth knowing they're on the recycling-first list rather than the straight-to-landfill list.

Why this matters for an older Appleton home

Renovation projects on older housing stock tend to generate a wider mix of debris than new construction — old plaster and lath, mixed-era flooring, outdated wiring, layers of old roofing. Sorting that mix correctly, rather than treating it all as one undifferentiated pile, is exactly what these rules are pointing toward: clean recoverable material handled one way, genuinely non-recoverable debris handled another.

Where a floodplain or wetland changes the picture

The exemption for clean brick, concrete, untreated wood, soil and stone comes with a real condition attached — it only applies away from floodplains, wetlands, surface waters and critical habitat. Given how much of the Fox Cities region sits along the Fox River and its tributaries, this isn't a hypothetical concern for every property. If your project is anywhere near water, it's worth double-checking before assuming a clean-fill exemption applies.

How this fits into a dumpster rental

When you rent a roll-off from us, proper sorting and legal disposal of what goes into it is handled on our end — you don't need to become a DNR compliance expert to do a kitchen remodel. But it does help to flag anything unusual up front — old insulation, potential lead paint, a large volume of concrete or masonry — so we can size the container and plan disposal correctly from the start.

A simple rule of thumb

If it's clean and untreated — plain wood, brick, concrete, soil, stone — it has real disposal flexibility under Wisconsin rules. If it's painted, treated, mixed, or clearly hazardous, treat it as material that needs proper handling rather than a backyard burn pile or a mixed dumpster load with no sorting at all.

Renovation debris versus new-construction debris

The same NR 500–538 framework covers both, but the practical mix looks different depending on the project. New construction tends to generate cleaner, more uniform material — lumber offcuts, packaging, drywall scraps — that sorts easily. Renovation and demolition debris, especially from an older structure, is more likely to include painted or treated material, mixed flooring layers, and items that need a closer look before they go in with everything else.

Questions about your specific project?

Every renovation or demolition throws up its own edge cases. Call us and describe what your project is generating — we haul debris out of Appleton and the wider Fox Cities every week and can tell you plainly how a given material should be handled before it ever hits the container.
