Trees in Montgomery County, MD

No permit is needed to remove a tree on an existing house lot by itself. Once your project needs a sediment control permit, the Tree Canopy Law (Ch. 55) applies and requires shade tree planting or a fee. Larger development falls under Forest Conservation (Ch. 22A) instead. Trees in the right-of-way need a Roadside Tree permit.
