Tree Cutting Rules & Permits in Greater Portland

The Default: Your Inland Lot, Your Trees

For a tree standing wholly on your own property, away from the water and the street, Maine towns generally require no permit for removal: not in Portland, not in the suburbs. You can remove it, prune it, or clear the whole overgrown back acre on your own schedule. The rules below are the exceptions, but they're exactly where the expensive mistakes live.

Exception 1: Street Trees Aren't Yours

The maple between the sidewalk and the curb (even directly in front of your house, even if you've raked its leaves for thirty years) is a city tree in the public right-of-way. Portland (like South Portland, Westbrook, and most area towns) requires city approval, through the city arborist/forestry program, before street trees are pruned or removed, and unauthorized cutting is a municipal violation. If a street tree is dead, dangerous, or tearing up the sidewalk, report it to the city rather than calling a crew; it's their tree and their bill, which is the good news version of "not yours."

Exception 2: The Shoreland Zone, Maine's Big One

Any property within 250 feet of the ocean, a river, a great pond, or most streams and wetlands sits in Maine's shoreland zone, where vegetation removal is regulated hard, and a large share of Greater Portland's best lots qualify, from Casco Bay shorefront to the Presumpscot to Sebago-area camps.

• The first 75 feet from the water is a buffer where clearing is essentially prohibited: no openings in the canopy beyond a narrow, winding footpath, limited pruning only. This is where "I just wanted to see the water" becomes a violation.
• From 75 to 250 feet, towns use a point system: each tree is scored by trunk diameter, and every 25×50-foot plot must keep a minimum score; in practice, you can thin selectively (typically up to ~40% of the points per 10-year period) but never clear-cut.
• Enforcement is real. Fines, after-the-fact permits, and mandatory replanting orders happen every season, and shoreline neighbors do report. The town keeps the file forever; it surfaces at resale.

The good news: a legal, well-designed selective cut (a view corridor rather than a clearing) usually achieves the light and the water view people actually wanted, while keeping the privacy screen and the property value. That's a planning exercise: walk it with a crew that works shorefront regularly, and get the town's sign-off in writing before a saw starts.

Smaller Print Worth Knowing

• Your neighbor's trees are never yours to cut: Maine's timber trespass law awards double or treble damages, even for well-intentioned "help." The neighbor's-tree guide covers overhanging limbs and the property-line rules.
• Subdivisions and HOAs sometimes add their own tree covenants (especially view and buffer plantings); check the deed before a big clearing project.
• When in doubt, one phone call: the town's code enforcement officer will tell you in five minutes whether your project touches any of this. Free, and it beats the alternative conversation with the same office later.

The Practical Version

Inland and off the right-of-way: proceed. Near the street: it's probably the city's tree. Within sight of water: assume the shoreland rules apply until confirmed otherwise. And for any project bigger than one tree, get the estimate walked on-site; the zoning questions get answered in the same visit that prices the work.
