Pennsylvania requires anyone performing $5,000 or more of home improvement work per year to register with the state Attorney General’s Office — and landscapers are explicitly included when they build retaining walls, patios, drainage systems, walkways or lighting. That registration number is the most useful thing you can ask a Philadelphia contractor for. This page lists landscapers serving Philadelphia.
What Philadelphia landscapers handle
Rowhouse garden design — small rear yards, often walled, reached through the house or a narrow shared alley. Design quality matters because you see the whole garden at once.
Front stoop and street-frontage planting, where salt and foot traffic both apply.
Hardscape — patios, walls, steps — which is precisely the work triggering PA registration requirements.
Maintenance across a season running roughly April through November.
Container and roof-deck planting in the denser neighbourhoods.
Licensing: PA’s HIC registration
Pennsylvania has no landscape-specific trade licence, but it does have the Home Improvement Contractor Protection Act (HICPA), which requires all contractors performing at least $5,000 worth of home improvements per year to register with the Pennsylvania Office of Attorney General.
Landscapers are explicitly covered when the work includes retaining walls, fountains or drainage systems, or construction, replacement, installation or improvement of driveways, porches, patios, non-decorative fences, concrete walkways, lighting systems and similar.
The threshold is on annual revenue, not per job: a landscaper whose total home improvement revenue stays below $5,000 in a calendar year is not required to register. In practice, any established Philadelphia landscape company doing hardscape work is well past that and should hold a registration number.
Ask for the number and verify it with the Attorney General’s office. Registration is not a competence test, but it does mean the business is identifiable, has provided insurance information, and can be pursued if something goes wrong — which is more than an unregistered operator offers.
Street trees require city permission. Trees in the sidewalk are managed by the city, and planting, pruning or removing them generally requires a permit. Confirm before touching anything in the sidewalk zone.
Verify general liability and workers’ compensation directly.
What’s specific to Philadelphia
Rowhouse gardens and access. Most Philadelphia houses are attached, which means rear gardens are frequently reachable only through the house or via a narrow shared alley. Everything — soil, stone, plants, debris — moves by hand.
This is a legitimate and substantial cost driver, and it’s why hardscape quotes vary so widely between contractors who walked the site and those who estimated from a photo. Never accept a patio or wall quote from someone who hasn’t seen the route in.
Shared alleys add a second complication: access may require a neighbour’s cooperation, and that’s worth settling before work is scheduled rather than on the morning the pallets arrive.
Urban fill and soil contamination. Philadelphia is an old industrial city, and residential soil in many neighbourhoods is fill of uncertain origin — construction debris, ash, historic industrial deposits. Two practical consequences:
- Drainage and structure are unpredictable. What’s under the top few inches may be rubble
- Soil testing matters if you plan to grow food. Older urban soils can carry lead, particularly near former industrial sites and adjacent to houses with historic lead paint. Raised beds with imported soil are the standard response for vegetable growing
A landscaper who suggests testing before you plant an edible garden is giving you good advice, not upselling.
Road salt. Winter de-icing damages street-level plantings — salt spray burns evergreens and shrubs along streets, and salt-laden snow piled onto beds during clearing poisons soil for the following season. Salt-tolerant species at street level and thoughtful snow placement both help.
Freeze-thaw and hardscape. Philadelphia cycles through freezing and thawing repeatedly each winter, which destroys under-built paving. Base preparation depth determines whether a patio stays flat. Bids differing by thousands usually differ there — ask explicitly and get it in writing.
Zone 7b, with real winter. Milder than New England but with genuine hard freezes. The plant palette is generous, spanning many southern and northern species, but marginal material planted during mild years eventually gets caught.
Humid summers. Fungal disease pressure in turf is real, and small shaded rowhouse yards keep foliage damp. Water early morning; avoid evening irrigation.
Historic districts. Properties in certified historic districts may face review for visible changes including fencing, paving and structures. Confirm before altering anything street-facing.
Pricing expectations
Philadelphia figures for 2026, from the Water Department and the City:
- Philadelphia pays you to remove paving, not lawn. Through PWD’s Rain Check, the city contributes $20 per square foot for permeable pavers, to a maximum of $2,500, and $22 per square foot towards a rain garden, also capped at $2,500
- PWD’s own stated market costs, against which those contributions are set: removing concrete or asphalt and installing permeable pavers “normally costs about $40–60 per square foot“
- Also through Rain Check: rain barrels are free, metal downspout planters cost $100, and a full property assessment costs $25, non-refundable and not credited against installation
- The stormwater charge on your bill rises on 1 September 2026 to $20.89 a month for the stormwater management service, plus $2.16 billing and collection, for a residential property
- A retaining wall 2 feet or taller needs a permit. On a one- or two-family dwelling the permit is a flat $69, plus a $25 filing fee and $3 city and $4.50 state surcharges
- Street trees are free from the city — and Parks & Recreation prunes and removes hazardous ones at no cost to you. Any major pruning or removal of a street tree needs their permit
Philadelphia inverts the western rebate. Phoenix and Las Vegas pay you to take grass out; Philadelphia pays you to take concrete out, because its problem is stormwater rather than scarcity. At $20 to $22 a square foot against a stated market cost of $40 to $60, Rain Check covers a real share of a depaving job up to its $2,500 cap — and the eligibility rules are the part a national contractor will not know. Permeable pavers are only installed in place of an existing hard surface, never on a bare patch, and never on a public sidewalk or anything in the public right of way. A rain garden must sit at least 10 feet from a below-ground basement or crawlspace and is excavated 6 to 12 inches deep. All properties must be residential — commercial and institutional are excluded — and renters may apply provided the owner signs the waiver first. PWD provides up to one free rain barrel and one cost-share tool per eligible property.
The reason any of this pays is the second bullet’s twin: your stormwater charge is driven by impervious area, and the tariff defines that to include compacted and hardscaped surfaces directly. Taking up paving is the one landscaping decision in this city that reduces a monthly bill rather than only a seasonal one — and that bill goes up again on 1 September.
Two other City rules save money or trouble. Trees in the sidewalk are the city’s job: Parks & Recreation plants street trees free on request and prunes or removes hazardous ones at no charge, so a contractor quoting to take down a street tree is quoting for work the city may do for nothing — and which needs their permit and a certified arborist regardless. And on snow, the ordinance is specific: a path not less than 36 inches wide within six hours of the end of a snowfall, with narrower pavements cleared to a minimum of 12 inches, and snow may not be piled into the street. Fines run $50 to $300.
One irrigation rule to read carefully rather than accept as quoted: the City’s landscape code does require irrigation systems to be designed and installed to a standard — but it applies only to development on lots greater than 5,000 square feet, not to an ordinary rowhouse garden.
These are ranges local landscaping companies publish for this metro rather than survey data, so treat them as a bracket to check a quote against, not a price list.
Two contract items: Rain Check eligibility confirmed before work starts — permeable pavers only replace an existing hard surface, and never in the public right of way, and whether the tree in question is a street tree, which Parks & Recreation may prune or remove free.

How this directory helps
Every landscaper here is listed with business name, address and phone so you can verify them yourself.
Three questions sort Philadelphia contractors. Ask for the PA Attorney General HIC registration number if the job involves hardscape or drainage. Ask whether they’ve seen the access route to your rear garden. And if you’re planting food, ask whether they’d test the soil first — in a city this old, that’s the right instinct.
