A container in New Jersey can need two separate approvals: a construction permit under the state code and zoning approval from the town where it will sit. Newark, Jersey City and Trenton each add rules of their own.
The first question is about construction: New Jersey's Uniform Construction Code makes it unlawful to construct a structure, or to change the use of a building or structure, without first applying to the local construction official and getting the required permit (N.J.A.C. 5:23-2.14(a)).
The second question is about land use: whether a container may sit on your lot at all, where on the lot, and for how long. That answer comes from the zoning office of the municipality where the lot is. New Jersey has 564 municipalities, according to the state's own count, so the answer for a lot in Newark can differ from the answer one town over.
A container can be exempt from a construction permit and still need zoning approval.
The construction code exempts small sheds from a construction permit for building work. The rule reads:
"A construction permit for building work shall not be required for garden-type utility sheds and similar structures that are 200 square feet or less in area, 10 feet or less in height, and accessory to buildings of Group R-2, R-3, R-4, or R-5 and which do not contain a water, gas, oil, or sewer connection. A construction permit for electrical work shall be required, when applicable."
That is N.J.A.C. 5:23-2.14(b)8, in the Department of Community Affairs copy current through the August 17, 2026 New Jersey Register. A 20ft container covers 160 square feet and stands 8 feet 6 inches tall. A 40ft container covers 320 square feet, which is over the limit.
Groups R-2 through R-5 include apartment buildings and one- and two-family homes, so the exemption covers a shed that serves a home or an apartment building. The list leaves out Group R-1, which New Jersey's building subcode uses for hotels, motels and vacation timeshare properties (N.J.A.C. 5:23-3.14). The rule names sheds "and similar structures". Whether a container counts as a similar structure is the construction official's decision, so ask before you rely on the exemption. Lights or outlets inside the container still need an electrical permit.
Newark's Zoning and Land Use Regulations (Title 41, November 2023, amended September 5, 2024) deal with containers in two places.
The definitions in § 41:2-2 count a shipping container used for on-site storage as a portable storage unit. A portable storage unit may not sit in a required front or side yard. The rule limits units to one for every two contiguous acres in common ownership. If your lot is under two acres, ask the Office of Planning and Zoning whether a unit is allowed there. A portable storage unit may be used only for storage. It must be removed within 180 days.
The use tables list portable storage units as a permitted accessory use in the R-1 through R-6 residential zones and in the C-3 and MX-2 zones. In the I-1, I-2, I-3, port and airport zones they are conditionally permitted.
Chapter 22 defines a stored container as one "placed or left on a property and otherwise not placed in transit for a period of more than 30 days." Section 41:22-2 bars stored shipping containers in the residential zones (R-1 through R-6), the commercial zones (C-1, C-2 and C-3), the mixed-use zones (MX-1, MX-2 and MX-3), institutional zones and redevelopment areas, unless a redevelopment plan expressly allows them. Fines are charged per container for each day of storage.
Where the zoning allows container storage, the application goes through site plan approval by the Central Planning Board, which reviews how much of the parcel the containers cover, grading, drainage and environmental conditions (§ 41:22-6). Stacks are limited to four containers.
The same chapter licenses container storage. It defines a shipping container operator as "any owner, manager, company, or other entity that stores shipping containers" on property in Newark (§ 41:22-1). An operator storing containers in any zoning district needs a Shipping Container Storage License from the city, renewed every year (§ 41:22-3), and reports the containers on site to the Office of Planning and Zoning on the last business day of each month (§ 41:22-5). On the site, containers need enough space between them for inspection and rodent control, and surveillance cameras must be installed (§ 41:22-6).
The portable storage unit rule allows up to 180 days in the residential zones, and Chapter 22 bars containers left there more than 30 days. Ask the Office of Planning and Zoning which rule applies to your lot. On a lot where container storage is allowed, ask the office too how the city applies the storage license to a business keeping its own containers. The office is in Room 112 at City Hall, and its number is 973-733-6333. Its page links to an interactive zoning map that shows each parcel's zone.
On August 5, 2026, the Municipal Council sent a proposed amendment of Chapter 22 to the Central Planning Board for review (resolution 26-1052). The proposal would revise the chapter's rules and fees, so the limits above may change. When you call, ask whether the amendment has been adopted.
Jersey City's Construction Code office states that "Zoning approval is required for all shed installations," in the same answer where it repeats the state exemption quoted above (permit FAQ). The Division of Zoning takes applications only through the city's online permitting portal, not in person. Its number is (201) 547-4832.
The zoning code lists storage sheds as a permitted accessory use in the city's RH-1, RH-2, R-1, R-2, R-3 and R-4 residential districts (§§ 345-40 to 345-44). The general rules for accessory structures in § 345-60(I) are:
Ask the Division of Zoning whether it reviews your container as a shed or as another accessory structure.
Under § 296-5.1, nothing that can block traffic or pedestrians may be placed in the public right-of-way, including the parking lane, without a permit from the Division of Engineering, Traffic and Transportation. A permit for a portable moving storage container, the kind a moving company drops off, lasts no more than three calendar days and cannot be extended (§ 296-5.3). An object permitted in the street must sit at least 25 feet from an intersection (§ 296-5.4). A container you buy belongs on private property.
Trenton's Land Development Ordinance, adopted December 21, 2023, lists a temporary outdoor storage container as a temporary use in every zoning district. Its temporary use standards (section 8.5, item H) set these limits:
The ordinance defines these containers as self-storage units that are picked up and returned to a warehouse, which does not describe a container you buy and keep. It defines a structure as "a combination of materials that form a construction for use, occupancy, or ornamentation," and section 13.12 requires a zoning permit from the Zoning Officer before a structure is erected. To ask how a container you plan to keep will be reviewed, start with the city's Division of Planning at 609-989-3512, which reviews development requests for the Planning Board and the Zoning Board of Adjustment.
Container One requires 110 feet of straight, unobstructed space for a 20ft container and 130 feet for a 40ft. The truck needs at least 15 feet of height to drive in, 22 feet of height along the entire unloading path and 10 feet of width (Container One FAQ).
On a city block, the 110 feet often have to come from the street and the driveway together. Street trees, overhead wires and parked cars can each stop a delivery, so walk the route before you order.
This guide is general information, not legal advice. Rules change, so confirm them with the zoning office and construction official for your lot before you order.
