Landscaping Rules in Pittsburgh, PA

If you live in Pittsburgh or are thinking about moving there, landscaping rules are one of those things you probably won't think about until they affect you directly. Pittsburgh has 6 specific rules on the books covering different aspects of landscaping rules, and some of them might surprise you.

Weed Ordinances

Pittsburgh requires property owners to cut noxious weeds and mow grass to no more than six inches, or face a nuisance citation and cleanup lien from the City.

Key details: Height limit: 6 inches for grass and weeds. Compliance notice: 5 days to fix after notice. Individual fine: Up to $15 plus court costs. Commercial/multi-family fine: $50 to $500 plus court costs. Enforcement: Dept. of Public Works can abate and bill.

Fine up to $15 plus court costs for most owners; $50 to $500 plus court costs for multi-family buildings with six or more units, or commercial, institutional, and municipal properties. Each day of noncompliance is a separate offense.

Composting

Pittsburgh classifies composting as urban agriculture under its zoning code and requires compost structures to sit at least one foot from property lines, contained in a bin or defined pad, with drainage and pest controls.

Key details: Setback: At least 1 ft. from property lines. Container: Bin, pad, brick, block, wood, or mesh. Zoning use: Urban Agriculture under § 912.07. Banned materials: Meat, dairy, oil, plastics, pet waste.

Composting violations fall under Chapter 619's enforcement schedule: $50 for a first violation at a single-family home (up to $500 for repeat violations), $100 for multi-family buildings, and $1,000 for commercial sites, with each day a separate violation.

Native Plants

Pittsburgh property owners may install and maintain native-plant landscaping, rain gardens, and pollinator gardens under a 2025 ordinance, but must register the planting with the City.

Key details: Governing section: Pittsburgh Code § 609.08. Effective date: January 1, 2026. Registration: Required with City overgrowth-inspection dept.. Border requirement: Distinct edge or fence up to 4 ft.. Excluded species: PA-invasive or noxious-listed plants.

Registration can carry a fee set by the inspecting department. An unregistered or noncompliant bed can be cited as a weeds/overgrowth violation and, after a notice period, penalized under Property Maintenance Code § 106.3 (Ch. 1004): separate from the flat $15–$500 weeds fine in § 609.07.

Tree Removal & Heritage Trees

Pittsburgh requires a Department of Public Works permit before removing, cutting down, or trimming any tree or shrub located in a public street, parkway, or other public place.

Key details: Permit required: DPW permit to remove or plant. Applies to: Public street & public-place trees. Annual permits: Available to tree-trimming companies. Damage to public trees: Owner billed for repair costs.

Cutting down or removing a public street tree without a DPW permit violates Code § 483.03(a). Accidental or willful damage to a public tree must be reported within 48 hours, and repair or replanting costs are billed to the responsible party under § 485.01.

Tree Trimming

Pittsburgh property owners must trim trees whose limbs extend into a public street, block free passage, obstruct a streetlight, or interfere with fire alarm wires once Public Works issues a written notice.

Key details: Minimum notice period: 10 days to trim. Enforcing agency: Department of Public Works. If ignored: City trims and bills owner. Removal: Separate permit required.

Ignore a trim notice and Public Works trims the encroaching limbs itself and bills the owner for the cost; cutting down a street tree without a § 483.03(a) permit is a separate violation.

Water Restrictions

Pittsburgh has no standing outdoor watering ban. PA Code Chapter 119 authorizes restrictions only during declared drought emergencies. Pgh2O may impose temporary limits during supply shortages.

Key details: Standing Restrictions: None -- no permanent watering ban. State Authority: 4 Pa. Code Chapter 119 (drought emergencies). Water Provider: Pittsburgh Water (Pgh2O). Oversight: PA Public Utility Commission.

The rules around water restrictions in Pittsburgh lean permissive, but that does not mean anything goes.
