Selling a Manufacturing Plant or Factory Building

This page is for owners of a manufacturing plant, factory building or machine shop in Philadelphia, its Pennsylvania suburbs or South Jersey. The plant might be running, winding down or already empty.

We buy manufacturing plants, and we're part of a family-owned business that has been operating for over 15 years. We buy the real estate, so what happens to your company stays your decision.

Can you sell a manufacturing plant without selling the company?

A manufacturing plant can be sold apart from the company that runs in it. The buyer takes the building and the land. The company can be sold to someone else, closed, moved or kept running in the building as a tenant. Whichever entity holds title to the real estate is the seller.

A business sale and a real estate sale are different deals. A business sale transfers the operation, such as its customers, staff, contracts and equipment. A real estate sale transfers the land and the building. When the building sits in its own company that leases it to the operating business, that holding company signs as the seller.

An owner who wants to keep the plant running can look at a sale-leaseback. You sell the real estate and sign a lease to stay, and the lease terms are written into the deal. An owner who is retiring or selling the company can time the building sale around the company's sale or closing. Our page on retiring or selling the business covers the order of steps.

Is there demand for manufacturing buildings around Philadelphia?

Manufacturing buildings in CBRE's Philadelphia market were 4.9% vacant in the third quarter of 2026. That compares with 12.8% for distribution and logistics buildings, 8.1% for research and development (R&D) and flex buildings and 11.1% overall. Occupied manufacturing space grew by 123,000 square feet in the quarter, though it shrank by 477,000 square feet over 2026 through September.

CBRE's Philadelphia market takes in South Jersey and Northern Delaware. In the third quarter of 2026, CBRE tracked 58.79 million square feet of manufacturing space there, about 15% of the 387.59 million square feet it follows, by our arithmetic. Another 1.40 million square feet was under construction. Its average direct asking rent for manufacturing space was $8.84 per square foot a year, triple net.

Cushman & Wakefield's regional totals, which leave out Northern Delaware, put manufacturing asking rents below warehouse rents. Its weighted average net asking rent for manufacturing space across the region was $9.52 per square foot a year in the third quarter of 2026. Warehouse and distribution space was $12.97. By county, it lists manufacturing rents only for Lower Bucks ($9.84), Upper Bucks ($9.85), Montgomery ($8.29) and Burlington ($12.50).

The Federal Reserve Bank of Philadelphia's October 2026 survey found that manufacturing activity in the region "continued to expand overall." Its current activity index did fall, from 37.8 in September to 20.9 in October. The bank's district covers Delaware, southern New Jersey, and eastern and central Pennsylvania.

The Bureau of Labor Statistics counted about 177,900 manufacturing jobs in the Philadelphia metro area in September 2026. That preliminary figure was 0.8% higher than a year earlier. Besides our seven counties, the metro area includes Chester County in Pennsylvania, Salem County in New Jersey, New Castle County in Delaware and Cecil County in Maryland.

Nationally, Cushman & Wakefield said manufacturers were the second most active tenant type in 2026 through September, accounting for more than one-fourth of leasing activity.

What do buyers check in a manufacturing plant?

Buyers of a manufacturing plant check what would be expensive to add or remove. That means the electrical service, floor slabs, cranes, compressed air, process water and drains, clear height and loading. They also review the permits the operation runs under and the site's environmental history, because a plant's past use shapes what the next owner takes on.

Records help a buyer trust what it sees. The crane rule of the federal Occupational Safety and Health Administration (OSHA) requires the rated load to be "plainly marked on each side of the crane." It also calls for monthly inspections of hooks and ropes, with certification records. For compressed air, OSHA requires a drain at the lowest point of every air receiver, a pressure gauge and safety valves tested at regular intervals. These are workplace rules for the operator, so a buyer will ask whether the records exist.

Prologis, the industrial real estate company, splits manufacturing buildings into heavy manufacturing and light assembly. It says heavy manufacturing buildings usually contain heavy-duty, often customized equipment, three-phase electricity and a lot of loading dock space. They "usually require a complete top-to-bottom renovation when there's a change in tenants," because of their permanent fixtures. A buyer who plans a new occupant or a different use prices that work in. Light assembly buildings, Prologis says, typically have lighter, more portable equipment. Roof, sprinkler and paving problems are covered on our page about selling a building that needs work.

In Pennsylvania, Act 2, the Land Recycling Program, is a voluntary cleanup program, and a sale doesn't trigger it. A buyer of a plant with old tanks or past contamination will still ask about them. Our page on environmental problems covers how Act 2 works when you sell and underground storage tanks.

Do a plant's environmental permits transfer to a buyer?

A plant's environmental permits don't pass to a buyer automatically with the deed. Pennsylvania's rules allow an air permit to be transferred only on an approved change of ownership. In Philadelphia, a buyer needs the City's prior written approval to keep discharging process wastewater. New Jersey has its own transfer filings for air and water permits.

Pennsylvania's air rules say a plan approval or operating permit can't be transferred except on an approved change of ownership. A plan approval is the permit needed before building or changing a source of air pollution. In the Pennsylvania suburbs, the Department of Environmental Protection (DEP) approves the change. For an operating permit, the ownership change can be handled as an administrative amendment, a paperwork change, when nothing else in the permit needs to change. That amendment takes a written agreement between the current and new permit holders. The agreement sets a specific date for the transfer of permit responsibility, coverage and liability, and it goes in with a compliance review form.

In Philadelphia, the City's Air Management Services handles the change of ownership on its own form. The filing includes a compliance review form for plan approvals and operating permits, plus a fee. Its July 2026 fee schedule lists $1,900 to transfer an operating permit and $900 for a plan approval.

The Philadelphia Water Department says an industrial wastewater discharge permit "is neither assignable nor transferable without prior written approval of City." A sale obligates the purchaser to seek that approval to keep discharging process wastewater. The City wants written notice of the intended transfer at least 30 days in advance.

New Jersey's air rules treat a transfer of ownership or operational control as an amendment. Depending on the permit, notice is due within 120 days after the change starts, or within 30 days of the change for an operating permit. An operating permit transfer also needs a written agreement between the current and new permit holders.

New Jersey's water discharge permits are called NJPDES (New Jersey Pollutant Discharge Elimination System) permits, and they cover stormwater from industrial sites too. They can transfer automatically if the current permit holder gives New Jersey's Department of Environmental Protection (NJDEP) written notice at least 30 days before the transfer date. The notice needs a written agreement with a specific transfer date and a notarized statement from the new permit holder's principal officer. The transfer goes through unless NJDEP sends a response letter within 30 days of getting the notice.

The sale agreement should say who files what, and when. If the buyer won't keep your process running, ask each permit office what closing out the permit takes. In Philadelphia, a plant with a wastewater discharge permit files a closure statement with the Water Department's Industrial Waste Unit at least 30 days before it shuts down.

New Jersey plants and ISRA

New Jersey's Industrial Site Recovery Act applies when a covered industrial business closes operations, or when the business or the real property it operates on changes hands. So selling the plant, or the company that runs it, can trigger ISRA. A business is covered when its NAICS code, the federal code for its type of business, is on the rule's list, subject to the rule's exceptions. It must also have operated in New Jersey on or after December 31, 1983. Its operations must have involved generating, manufacturing, refining, transporting, treating, storing, handling or disposing of hazardous substances or wastes.

On a sale, the owner or operator notifies NJDEP within five days after signing the sale agreement. A Licensed Site Remediation Professional (LSRP) then oversees the investigation and any cleanup, as NJDEP has required for ISRA notices filed since November 3, 2009. Closing doesn't have to wait for the cleanup to end. A Remediation Certification backed by a Remediation Funding Source (financial backing for the cleanup's cost) lets the sale go ahead while the work continues.

A plant can trigger ISRA without a sale. ISRA's rules count a cutback of at least 90 percent in the value of output within any five-year period as closing operations. A temporary stop of more than two years counts too. If a tenant runs the plant, the lease should say who handles ISRA, because the duties fall on the owner or operator. Our ISRA guide covers what triggers ISRA in a sale and how a sale can close before the cleanup is finished.

Does a plant's machinery go with the building when it sells?

The sale agreement decides which of a plant's machinery goes with the building. Machines, compressors and process lines can stay, be sold separately or be removed before closing. Tell us early what you plan to leave, take or sell, so the offer can list what's included. Removing heavy, built-in equipment can take time and money.

What happens to the machinery can change the taxes on the sale. Philadelphia's realty transfer tax regulations leave "permanently attached machinery, equipment, and improvements" out of taxable realty. The exclusion covers items used directly and exclusively in manufacturing, as a necessary and integral part of the process. Local ordinances elsewhere can have a similar exclusion. Hilltown Township in Bucks County, for one, excludes "permanently attached machinery and equipment in an industrial plant" from its transfer tax.

New Jersey's Realty Transfer Fee rules, as adopted in 2006, cover a deed whose price includes both real estate and personal property. They let the fee be figured on the real estate portion of the price. That takes a breakdown by a licensed New Jersey real estate appraiser, and the state's Division of Taxation can dispute it. Ask the title company how the current rule applies to your deed.

For a 1031 exchange, the IRS counts machinery or equipment as real property if it makes up an inherently permanent structure or a structural component of one. Machinery that state or local law classifies as real property counts too. The federal rule's own example treats a 12-ton manufacturing machine built to stay in place as real property. Your accountant can tell you how this applies to your plant, and the title company can tell you what the deed and transfer taxes cover.

Running, winding down or closed

A plant can sell while it's running, while it winds down or after it closes. Each choice comes with its own costs and rules.

Machinery Network, which sells used machinery, says machines shown "under power" draw more buyer confidence, so it advises selling while the plant still runs. It also advises spelling out who disconnects, rigs and loads each machine. Settle that before the building sale closes, and if you leave pieces in place, the sale agreement should say so.

Pennsylvania's bulk sale law can apply when a company sells 51% or more of its goods, fixtures, equipment, buildings or real estate. Our page on retiring covers the clearance certificate buyers ask for. In New Jersey, the state must receive the buyer's bulk sale notice at least 10 business days before closing.

An empty plant has rules of its own. In Philadelphia, it can need a Vacant Commercial Property License, backed by a bond or letter of credit. Our page on selling a vacant building covers when the license applies, carrying costs and insurance.

Can a buyer keep using the plant for manufacturing?

Whether a buyer can keep a plant in manufacturing depends on the plant's zoning and approved use. In Philadelphia, a new certificate of occupancy isn't required when ownership changes, as long as the approved use stays the same. A buyer planning a different use may need a zoning permit and a new certificate. Outside Philadelphia, check the municipality's zoning and permit rules.

Philadelphia's zoning code says its I-2 Medium Industrial district is for activities "such as manufacturing, distribution, processing, industrial parks." The same district covers other activities that may cause noise, odor, vibration or traffic well beyond the property line. I-1 Light Industrial covers lower-impact work such as light industry, assembly and fabrication. I-3 Heavy Industrial is for intensive, high-impact uses.

Zoning can change. In June 2026, the City Planning Commission approved, with amendments, a bill that would rezone 2730 Frankford Avenue from I-2 to RM-1, a residential multi-family district. Bills like that name specific parcels, so check your own property's current zoning. Our Philadelphia page covers how zoning affects an industrial sale, and our page on older buildings covers multi-story plants. Outside the city, our county pages cover the certificates some towns require at a sale: Bucks, Montgomery, Delaware, Camden, Burlington and Gloucester.
