Do you need a permit?
It depends on the tree
How close you are to water decides it. Duluth's tree preservation rules are in the Unified Development Chapter at section 50-25, and that section reaches only development or redevelopment on lots over 10,000 square feet whose primary structure is multi-family, mixed use, commercial, institutional, industrial or parking — an ordinary single-family house is outside it. What catches homeowners instead is the Natural Resources Overlay: within 1,000 feet of Lake Superior, or 300 feet of a river, creek, stream or tributary, "all removal of natural vegetation" needs a shoreland permit. In a city threaded with creeks, that is a lot of back yards.
Size threshold
Duluth sets no diameter threshold for private tree removal. The tree preservation trigger is lot size and land use, not trunk size: section 50-25.1.C applies section 50-25.9 only to lots "that contain (i) more than 10,000 square feet of lot area, and (ii) a primary structure with a multi-family, mixed use, commercial, institutional, industrial, or parking principal use, as well as to any new lot of record created after November 19, 2010." Inside the shoreland overlay the trigger is location, and any amount of vegetation removal is covered.
What's protected in Duluth
- Natural vegetation, including trees, anywhere inside a shoreland area. Section 50-18.1.D.1 lists "(d) All removal of natural vegetation" among the activities requiring a shoreland permit.
- Trees and shrubs in a shore impact zone, where section 50-18.1.D.2(e) bans removal "in a contiguous patch, strip, row or block" outright — there is no permit to apply for.
- Trees in the city right-of-way, including boulevard trees, which section 50-25.2.L reserves to the city forester
- City trees on public grounds, which residents may not remove at all under section 35-28(a)(2)
Fees, penalties, and the ordinance
- Ordinance
- Duluth Unified Development Chapter (Legislative Code Chapter 50), section 50-25, Landscaping and Tree Preservation (Ord. No. 10044, August 16, 2010, as amended by Ord. Nos. 10096, 10153, 10160, 10286 and 10813, September 12, 2022); section 50-18.1, Natural Resources Overlay; UDC edition 08/25. Duluth Legislative Code section 35-28(a)(2) covers city trees.
Worth knowing
- The applicability clause is the whole answer for most homeowners. Section 50-25.1.C limits tree preservation to "all development or redevelopment on lots and parcels in any zone district that contain (i) more than 10,000 square feet of lot area, and (ii) a primary structure with a multi-family, mixed use, commercial, institutional, industrial, or parking principal use." A detached single-family home is not on that list.
- One trap in that same clause: it also reaches "any new lot of record created after November 19, 2010, regardless of the primary use of the property, in any zone district." If your lot was platted after that date, tree preservation can apply to your development or redevelopment even though you live in a single-family house.
- The shoreland overlay is defined broadly: it "applies to lands within 1,000 feet of Lake Superior or within 300 feet of rivers, creeks, streams and tributaries and floodplains, as designated on the NR-O map."
- Even where removal is allowed in a shoreland, section 50-18.1.D.2(d) requires that it "shall be designed to prevent erosion into regulated waters and to preserve shoreland aesthetics."
- Removing invasive species inside the naturally vegetative buffer is allowed "with an approved shoreland permit, provided there is replacement with non-invasive and non-harmful species" (section 50-18.1.D.4(b)(vi)).
- On boulevard and right-of-way trees the UDC is short and clear: "Tree removal or planting in city rights-of-way shall be done only with the approval of the city forester" (section 50-25.2.L).
- The city's FAQ answer on city trees is direct: "No, the City of Duluth does not allow citizens to operate power equipment on city property. Removing city trees is against City Code Section 35-28(a)(2)."
- Duluth publishes the UDC as one PDF per section rather than as web pages, which is why an earlier pass could not read section 50-25.
What we could not confirm
We would rather tell you what we don't know than guess. Call the office below to confirm these before you cut.
- — Whether your specific lot sits inside the shoreland overlay. Duluth maps it on the NR-O map; call Planning and Development at 218-730-5580 to check before you cut.
- — The shoreland permit fee and processing time.
- — The penalty for removing vegetation in a shoreland without a permit, and the penalty for removing a city tree.
- — Whether Duluth licenses tree care contractors.
- — Whether Duluth imposes a seasonal oak wilt pruning restriction. We found none in the UDC sections we read, but we did not read the full Legislative Code.
