Selling an Older Warehouse or Industrial Building

This page is for owners of an industrial building that the market calls dated. It might be a 1960s warehouse with low ceilings, a plant with two dock doors or a multi-story loft building in Philadelphia. It might also be a flex building with more office than today's tenants want. It covers how buyers judge these buildings, who buys them, and how to sell one as it stands.

We buy older and functionally obsolete buildings across Philadelphia and South Jersey. We're part of a family-owned business that has been operating for over 15 years. Low clear heights and odd layouts are part of what we buy.

What makes an industrial building functionally obsolete?

An industrial building is functionally obsolete when its design limits what today's users can do in it. One limit is low clear height, the usable height under the roof structure. Too few loading docks, a shallow truck court, tight column spacing, little trailer parking, limited power or an outdated sprinkler system can do it too. So can several floors instead of one.

The market's yardstick for modern space is high. CBRE defines Class A industrial space in the Philadelphia market as buildings built after 2000 with clear heights of 32 feet or more and ESFR sprinklers. Nationally, Cushman & Wakefield found that 54% of industrial deals of 500,000 square feet or more in the first quarter of 2026 were in buildings with 40-foot clear heights.

Obsolete doesn't mean unusable. A building that can't serve a big distributor can still suit a contractor, a small manufacturer or a local distributor. It can also suit a storage user, or a business that needs a showroom with space behind it. What changes is who the buyer is and how it prices the building.

Is there still demand for older industrial space?

In CBRE's figures, smaller buildings and non-Class A space have had lower vacancy than larger or Class A space. CBRE counted 5.0% vacancy in Philadelphia-market buildings under 50,000 square feet in the third quarter of 2026, against 18.8% for buildings of 500,000 to 749,999 square feet. In the first quarter, CBRE put Class A vacancy at 25.5%, against 6.5% for all other industrial space.

Part of the reason is supply. CBRE's January 2026 Philadelphia outlook said construction costs generally ruled out new buildings under 100,000 square feet. Its August 2026 midyear review called that very small range the clearest opening for developers. Little is under way, though: CBRE counted 173,000 square feet under construction in the third quarter, all in buildings of 50,000 to 99,999 square feet. That leaves small users choosing mostly among buildings that already stand.

Space that doesn't meet CBRE's Class A test is most of the market. In CBRE's first-quarter 2026 figures, Class A buildings made up 91.09 million of the 385.57 million square feet it tracks in the Philadelphia market. By our arithmetic, about 76% of the space didn't meet its Class A test. The trend has favored new space. In its second-quarter 2026 report, CBRE said Class A occupancy grew by more than 20 million square feet since mid-2022. Occupancy in all other industrial space shrank by about 10 million. In its fourth-quarter 2025 report, CBRE also described users consolidating from several outdated Class B or C buildings into one Class A building.

Nationally, Cushman & Wakefield's third-quarter 2026 report said that "as availability in newer facilities tightens, demand is beginning to spill over into older properties." It meant warehouses built from 2000 through 2019.

Who buys older warehouses and industrial buildings?

Older warehouses sell to owner-users, such as contractors, small manufacturers and local distributors who need space and don't need modern specs. They also sell to investors who lease space to small tenants, to buyers who plan a new use, and to developers who value the land. Each prices the building differently, so the same property can draw very different offers.

An owner-user pays for space it can use. An investor pays for the rent it expects to collect, minus what it will spend to get there. A buyer planning a new use, such as studios, storage or offices, prices the conversion. Philadelphia's own example of a change-of-use permit is converting a warehouse into artist studios. A developer prices the land after demolition. A direct offer from us is one more number to set against those. Our seller's guide explains how buyers decide what a warehouse is worth.

Is an older industrial building worth more as land?

An older industrial building is worth more as land only when the site would support a more valuable use after demolition. That depends on the zoning, the location and the cost of clearing it. Environmental history and demolition costs come off the land value. In June 2026, Philadelphia's Planning Commission approved bills that would rezone some industrial parcels.

In June 2026, the City Planning Commission approved a bill to remap parcels from ICMX, Industrial Commercial Mixed-Use, to CMX-3, Commercial Mixed-Use. It also approved, with amendments, a bill that included rezoning 2730 Frankford Avenue from I-2, Medium Industrial, to RM-1, Residential Multi-Family. Each bill covers a specific area of the city, not every industrial parcel. Check your property's current zoning before assuming its land value has changed.

Should you upgrade an older building before you sell it?

Upgrades to an older industrial building pay back only when buyers will pay more for the result than it cost. Some features they weigh, such as clear height and column spacing, are expensive or impossible to change. Smaller fixes can help a building show better, while big projects like adding docks or new power need a buyer who values them at more than they cost.

Repairs are a separate question from upgrades. A leaking roof or a failed sprinkler system is a defect, not a design limit. Our page on selling a building that needs repairs covers how buyers price that kind of work.

Multi-story buildings in Philadelphia

A building with several floors and freight elevators is at a disadvantage against a single-story warehouse for distribution. It can still suit light manufacturing, storage, studios and other uses the zoning allows. That makes zoning an early check for a buyer of a multi-story building in Philadelphia. Our page on keeping a plant in manufacturing covers zoning and the approved use.

The city's zoning code describes each industrial district's purpose. I-1 Light Industrial is for low-impact uses such as light industrial work, assembly, fabrication and local distribution. I-2 Medium Industrial covers manufacturing, distribution and processing. ICMX, Industrial Commercial Mixed-Use, is for commercial and low-impact industrial uses. IRMX, Industrial Residential Mixed-Use, mixes very low-impact industrial uses, including artists and artisans, with residential and neighborhood commercial ones. Our Philadelphia page covers how zoning affects an industrial sale and the city's industrial areas.

Zoning and building codes for a new use

A buyer who wants to use an older building differently has two hurdles. The first is zoning. In Philadelphia, changing a property's use takes a zoning permit. For properties other than one- and two-family homes, the City lists a $100 filing fee, applied toward the permit's final cost, and $189 for each permitted use. The second is the building code.

In New Jersey, existing buildings that are repaired, renovated or altered have to meet the state's Rehabilitation Subcode. A building whose use changes gets a certificate of occupancy only if it complies with that subcode. In Philadelphia, a change in occupancy classification under the Existing Building Code needs a new certificate of occupancy, according to the City. Elsewhere in Pennsylvania, ask the municipality what a change of use requires.

Neither hurdle is yours if you sell as-is. But they shape what a buyer can pay, which is why buyers ask about zoning and permits early.

What to have ready

• The building's size, clear height, number of docks and drive-in doors, and column spacing, if you know them
• Floor plans or a site plan, even old ones
• The zoning and the current certificate of occupancy
• Electrical service and sprinkler details
• Leases, if any part of the building is rented
• Environmental reports, especially for a building with a long manufacturing history

Selling an older building to us
