Tree Work in a City Built on Hillsides
Tree Service in Pittsburgh starts with the ground under the tree. The city runs from about 710 feet at the rivers to 1,370 feet at its highest point, and more than a quarter of its 90 neighborhood names refer to hills or heights. A maple on a flat lot in a suburb is a simple job. The same maple at the top of a retaining wall in Polish Hill, Troy Hill or Mount Washington, with a neighbor's roof below and only a set of public steps for access, needs a rigging plan before anyone starts a saw.
Who owns the tree in front of your house?
This is the first thing we sort out on a Pittsburgh visit, because it decides who is allowed to touch it. The City's Forestry FAQ says trees planted in the right-of-way become City property, even if a resident paid to plant them. The Forestry Division looks after right-of-way trees and park trees. Residents ask for pruning or removal of a City tree through 311 or the online request form; a Forestry supervisor inspects it and leaves a yellow card describing the work. The City's own page notes a backlog of roughly 18 months for non-emergency work.
If you want a private company to work on a City tree instead of waiting, the City requires a tree work permit application first, and its FAQ says private work on City trees must be supervised by an ISA Certified Arborist. The homeowner pays for that work and takes on the liability for it, and the City can charge restoration or mitigation costs for improper pruning. Our advice is simple: call the Forestry Division before anything is cut. For trees fully on your own lot, none of that applies, and we can quote the job directly.
Wet years and moving hillsides
Pittsburgh averages about 39.6 inches of precipitation a year, but 2018 brought 57.83 inches, the wettest year on record for the city. That year the region logged more than 200 landslides, and the city spent about $12 million on landslide cleanup, according to reporting by PublicSource. The soft rock locals call the Pittsburgh red beds weakens when it is soaked. A tree on a slope that has begun to creep may tilt, show exposed roots on the uphill side, or have soil cracks at its base. Those signs matter more here than in most cities, so we look for them on every hillside job.
What Pittsburgh jobs usually involve
- Crown cleaning and clearance pruning over narrow streets, alleys and parked cars
- Removing trees that lean toward houses built close together on small city lots
- Rope-and-rigging takedowns where no truck can reach the back yard
- Ash removal, since emerald ash borer has been in western Pennsylvania since 2007
- Spotted lanternfly checks on tree-of-heaven, which is common on vacant lots and slopes
- Stump grinding where machine access allows, and hand work where it doesn't

Pittsburgh Facts That Affect Tree Work
- Street trees belong to the City. Trees planted in the public right-of-way become City property. Pruning or removal requests go through 311, and private tree work on a City tree needs a tree work permit and must be supervised by an ISA Certified Arborist, per the Forestry Division FAQ.
- A canopy of about 42%. The 2012 urban forest master plan, written by Davey Resource Group for Tree Pittsburgh, estimated more than 2.5 million trees and roughly 42% canopy cover, much of it in parks and wealthier neighborhoods. A 2005 inventory counted 31,524 street trees.
- Record rain and landslides. 2018 was Pittsburgh's wettest year on record at 57.83 inches. More than 200 landslides hit the region, and the city spent about $12 million on cleanup that year.
- Hardiness zone 6b, 7a by the rivers. The city sits in USDA zone 6b, with milder 7a pockets along the rivers, and averages about 44 inches of snow a season. Heavy wet snow and ice load are a regular cause of broken limbs.
- Shade Tree Commission. Pittsburgh's Shade Tree Commission is set up under Title Four, Article XIII, Chapter 487 of the City Code and advises on spending the Shade Tree Trust Fund, which is funded partly by an outdoor advertising excise tax.

Pittsburgh Questions
Can I hire a private tree company to prune the City tree in front of my house?
Yes, but not without the City's say-so. Pittsburgh requires a tree work permit application, the work must be supervised by an ISA Certified Arborist, and you take on the cost and liability. Call the Forestry Division first; if the tree is yours rather than the City's, we can quote it directly.
The City says its backlog is long. What can I do about a dangerous City tree?
Report it through 311 and describe the hazard plainly, such as a split trunk over the sidewalk or a limb hanging on a wire. For anything touching power lines or blocking the street, call 911. We can't remove a City tree without permission, but we can deal with any of your own trees nearby.
My back yard is only reachable by steps. Can a tree still come down?
Usually, yes. On many Pittsburgh lots the tree is climbed and taken down in sections on ropes, and the wood is carried or lowered out by hand. It takes longer than a bucket-truck job, which is why access is part of the written estimate.
Is tree service near me in Pittsburgh affected by spotted lanternfly rules?
Allegheny County has been in the state's spotted lanternfly quarantine since 2020. That mostly affects moving wood and outdoor items out of the zone. We also flag tree-of-heaven on your property, since it is the insect's favorite host.
