Pennsylvania runs one construction code across the whole state and then hands placement decisions to roughly 2,560 separate municipalities.
Shipping container permits in Pennsylvania are not one permission. They are two separate questions, answered by two different levels of government, and a container can clear one and still fail the other.
The first question is a construction code question: does this structure need a building permit and inspections? Pennsylvania answers that at the state level. The Pennsylvania Construction Code Act, Act 45 of 1999, created the Uniform Construction Code, and the Department of Labor and Industry adopts the code editions that every jurisdiction in the Commonwealth then enforces. As of January 1, 2026 that set is the 2021 family of International Codes plus the 2020 National Electrical Code, adopted by final-omitted rulemaking published in the Pennsylvania Bulletin on November 8, 2025 (55 Pa.B. 8181). Accessibility is the one exception: a 2022 Commonwealth Court ruling enjoined the 2021 accessibility provisions, so the 2018 accessibility requirements stay in force until the Commonwealth adopts something new.
The second question is a zoning question: is a container an allowed thing to put on this particular lot, in this district, in this spot? Pennsylvania does not answer that at all. Your borough, township or city does. And because Pennsylvania has 67 counties containing roughly 2,560 municipalities, each writing its own zoning ordinance, the answers genuinely differ from one side of a township line to the other.
The short answer to "do I need a permit for a shipping container in Pennsylvania" depends on the municipality. A storage container on a single-family lot may need no building permit. A zoning check applies in every case. In Philadelphia, a standard 20ft container lands in a size band the city's own published guidance marks as not permitted.
The numbers that decide it. A standard 20ft container has a 160 square foot footprint (8ft by 20ft). A 40ft container is 320 square feet. A 40ft high cube is the same footprint at 9ft 6in tall. Pennsylvania permit and zoning thresholds can sit at 120, 130, 200, 250 or 1,000 square feet, so keep those two footprint numbers in mind while you read a local exemption list.
Before you call anyone, it helps to know one provision of the Pennsylvania Uniform Construction Code that applies to a container.
Under 34 Pa. Code § 403.1(b)(3), the UCC does not apply to the following structures where the structure has a building area of less than 1,000 square feet and is accessory to a detached one-family dwelling: carports, detached private garages, greenhouses and sheds. The regulation adds a clause that matters just as much: this exclusion applies "except as might be required by an ordinance adopted under section 503 of the act," meaning your municipality is free to impose stricter local requirements.
A 20ft container at 160 square feet and a 40ft container at 320 square feet are both far below 1,000 square feet. If your container is genuinely functioning as a shed on a lot with a detached single-family house, the statewide construction code largely steps aside. That is why a homeowner may be told "you do not need a building permit for that."
What that sentence never says is that you do not need zoning approval. The UCC governs how a building is built. It has nothing to say about whether the building belongs on your lot. Zoning is a separate question in Pennsylvania, and it is entirely local.
Two other exclusions appear in the same section. Agricultural buildings are excluded, which is why farm use can be the simpler path in rural Pennsylvania. And factory-built industrialized housing carrying the Commonwealth's insignia is excluded from the UCC because it is regulated separately, which we cover in our container homes in Pennsylvania guide.
In Philadelphia, a standard 20ft container lands in a size band that the city's own published guidance marks as not permitted.
The city's Zoning Code does not contain a section naming shipping containers. What Philadelphia does publish is a plain-language guidance sheet on sheds, which is the closest published analogue to a container sitting on a residential lot. The size bands are in its table (Philadelphia L&I, PG_011 Shed FAQ).
| Size of shed | Zoning permit | Building permit |
|---|---|---|
| 120 sq ft or less | Not required in the rear yard. Required in a front or side yard. | Not required |
| Over 120 and up to 130 sq ft | Required. Allowable per the Zoning Code, maximum 15 ft in height. | Not required |
| Over 130 and up to 200 sq ft | Required, but noted as not permitted per the Zoning Code | Not required |
| Over 200 sq ft | Required | Required |
Now run a 20ft container through it. At 160 square feet it lands squarely in the third row, the band Philadelphia's own guidance marks as not permitted by the Zoning Code. The city's note on that row is explicit: if an application includes a shed that is not permitted by the zoning code, L&I issues a refusal, and the route forward is an appeal to the Zoning Board of Adjustment, which requires a community meeting and a public hearing.
A 40ft container at 320 square feet lands in the fourth row instead, where the guidance calls for both a zoning permit and a building permit rather than a refusal. That is a genuinely counterintuitive outcome, and it is exactly the kind of thing worth confirming with L&I for your specific address and district before you order anything. Minimum yard and setback requirements apply throughout, and building permits are triggered separately by any electrical, mechanical or plumbing work regardless of size.
Two Philadelphia specifics to raise on that call. The city has a large number of historic districts and properties on the Philadelphia Register of Historic Places, which add a review layer above base zoning. And the Philadelphia Administrative Code continues to operate as a local construction code within the Uniform Construction Code framework, so Philadelphia has its own filing rules and its own transition schedule for the 2021 codes, with applications received on or after July 1, 2026 required to comply with the 2021 editions (L&I Code Bulletin B-2501).

Pittsburgh does not name shipping containers anywhere in its code either. In the full City Code, every occurrence of "container" sits in the solid waste, recycling and quality of life chapters. None of them are zoning provisions.
What Pittsburgh does have is an unusually clear published threshold for when you can skip zoning review. Under Pittsburgh Zoning Code § 922.02, a Record of Zoning Approval is required for all development subject to the Code, with a short list of exempted actions. One of those exemptions reads:
"One (1) story, detached accessory structures used as storage sheds, or similar unoccupied structures, provided the floor area does not exceed one hundred twenty (120) square feet in area, accessory to a Single-Unit Residential or Two-Unit Residential dwelling"
One hundred twenty square feet is the line. A 20ft container is 160 square feet and a 40ft is 320, so both clear it comfortably and neither is exempt. In Pittsburgh, a container on a residential lot means a Record of Zoning Approval. The same section also requires a Certificate of Occupancy for a structure erected, altered or enlarged, with narrow exceptions for interior renovation, exterior renovation that does not change the footprint, and concrete on grade.
One more clause in that section matters in Pittsburgh. All of those exemptions fall away if the property sits within a Chapter 906 Environmental Overlay District, the city's landslide-prone and steep-slope overlay. Pittsburgh's hillsides are extensive, so this is worth checking early rather than late.
Chapter 912 lists accessory uses and structures permitted by right in Residential and H Districts. The list includes "playhouses, patios, cabanas, porches, decks, gazebos and incidental household storage buildings" at § 912.02(9), and closes at § 912.02(17) with "other necessary and customary uses determined by the Zoning Administrator to be appropriate, incidental and subordinate to the primary use on the lot." That last clause is the door a container walks through, and it is a judgment call by a named official rather than an automatic yes.
The development standards at § 912.04 then apply, so check them before you pick a size:
Start with the Department of City Planning for the zoning question, and the Department of Permits, Licenses and Inspections for the construction side. See our Pittsburgh container delivery page for depot detail and the access constraints that come with the city's grades.
Allentown's zoning ordinance is new, and guidance written before 2026 describes a code that no longer applies. City Council adopted a wholly new Zoning Ordinance, No. 16166, on October 15, 2025, repealing the previous Chapter 660 that had been in place since 2010.
Like the other two, the new ordinance does not name shipping containers. It takes a structured approach instead. Section 660-41 allows only those accessory uses and structures expressly identified in the chapter, plus those that the Zoning Officer determines meet four tests: customarily found with the principal use, subordinate and clearly incidental to it, operated by the owner or lessee, and serving a necessary function for the comfort, safety or convenience of the owner or lessee.
If the Zoning Officer reads your container as an outbuilding, § 660-49 is the governing section. Outbuildings are defined as completely enclosed accessory buildings detached from the principal building, with detached garages, sheds, barns, workshops and greenhouses given as typical examples. The general standards that follow are specific and easy to check against a container:
One clause that can catch a 40ft container is the design rule at § 660-41.B(7): accessory buildings with a footprint of 250 square feet or more that are visible from an A or B street must comply with the roof type and building material regulations that apply to the principal building on the lot. A 20ft container at 160 square feet stays under that threshold. A 40ft at 320 square feet does not, which turns a corrugated steel box into a design conversation rather than a placement one.
If the container is being read as outdoor storage rather than as a building, § 660-51 applies instead. Outdoor storage areas count toward the maximum building coverage on the lot and must be enclosed by a durable permanent fence at least six feet high, screened per the buffer regulations in Article 8. And for genuinely temporary use, § 660-57.B lets the Zoning Officer issue a temporary permit for storage areas necessary as part of active construction on the same or an adjacent lot, for up to one year, renewable once for good cause, after which continuation requires Zoning Hearing Board approval.

Three cities is a small sample of a state with roughly 2,560 municipalities, so it helps to know the structural patterns that repeat.
Pennsylvania municipalities zone under one statute, and Philadelphia and Pittsburgh do not. The Pennsylvania Municipalities Planning Code, Act 247 of 1968, is the enabling law for local zoning. Its enacting clause empowers "cities of the second class A, and third class, boroughs, incorporated towns, townships of the first and second classes including those within a county of the second class and counties of the second class through eighth classes" (Pennsylvania Municipalities Planning Code). Philadelphia is a city of the first class and Pittsburgh is a city of the second class. Neither appears in that list, which is a large part of why their zoning codes read so differently from the townships around them. Allentown, a third class city, does zone under the MPC.
Who enforces the construction code depends on whether your municipality opted in. Each Pennsylvania municipality elects whether to administer and enforce the UCC locally, using its own employees or certified third party agencies. In municipalities that opted out, the Department of Labor and Industry handles all commercial enforcement, and residential enforcement runs through certified third party agencies that the property owner or contractor hires directly (Pennsylvania Department of Labor and Industry). If your township tells you it does not issue building permits, that is what is going on, and it does not mean the code stopped applying.
Counties rarely settle it. Unlike states where county zoning is the default, Pennsylvania zoning is overwhelmingly municipal. County planning offices are useful for maps, floodplain data and comprehensive plans, but the ordinance that governs your lot is the borough's, township's or city's.
Agricultural land can carry lighter rules. Agricultural buildings are excluded from the UCC outright, and some Pennsylvania townships treat farm storage lightly in their zoning as well.
A Pennsylvania jurisdiction that allows containers at all may draw a line between a container tied to a specific, time-limited activity and a container that simply lives on the property.
Temporary means the container supports an active project: a renovation, a build under a valid permit, a move. Allentown's rule is one example of how this can be written: tied to active construction on the same or an adjacent lot, capped at one year, one renewal for good cause, then a board hearing. Duration caps elsewhere in Pennsylvania vary by municipality and by trigger.
Permanent means the container stays. That is when setbacks, lot coverage, screening, height, design standards and, in Philadelphia's case, a published size band come into play. If you intend permanence, plan for it at the zoning counter rather than learning about it from an enforcement notice.
Start with one call to your municipal zoning office, with your property address in hand. Ask these, in this order:
Write down the name of the person who answered. If the answer later turns out to be wrong, that name is worth having.
We sell containers across Pennsylvania, and Container One delivers them. We are not your permit office, we do not file applications for you, and we do not interpret your ordinance. For the conversation with your zoning officer, the container specifications are the exact external dimensions, footprint, height, weight, door swing, and the clearance the delivery truck needs.
As of 6 August 2026, Pennsylvania delivered pricing starts at $2,157 for a 20ft wind and water tight container delivered in Philadelphia. Philadelphia and Allentown are both served from the Newark depot, which is why their numbers track closely. Pittsburgh is served from Cleveland at a longer haul. Here is the current picture across our three cities.
| City | 20ft WWT | 40ft WWT | 40ft High Cube WWT | Serving depot |
|---|---|---|---|---|
| Philadelphia | $2,157 | $2,491 | $2,438 | Newark NJ, 86.5 mi |
| Pittsburgh | $2,591 | $2,909 | $2,996 | Cleveland OH, 132 mi |
| Allentown | $2,279 | $2,491 | $2,438 | Newark NJ, 82.4 mi |
Every price above includes delivery. Note that the 40ft high cube runs slightly below the standard 40ft out of Newark and slightly above it out of Cleveland, so it is worth asking about both rather than assuming the taller box costs more. If you would rather spread the cost, ask about rent-to-own when you request your quote.
