Manufacturing & industrial property tax consulting
Manufacturing plants are usually assessed by the cost approach, which starts from replacement cost and subtracts physical wear. That method reliably overstates value for a special-purpose facility, because it captures none of the functional and economic obsolescence that makes a purpose-built plant worth far less than it cost. CPT quantifies that obsolescence and separates equipment the assessor has folded into the real estate.
The cost approach on a building with no second user
Industrial assessments are usually built from replacement cost new less depreciation. The assessor prices the structure from a cost manual, subtracts an age-based allowance for physical wear, and stops. What that produces is the cost to reproduce your plant, not what anyone would pay for it.
A plant designed around one process is rarely worth its cost. Heavy foundations poured for a press that is no longer made, forty feet of clear height in a building that needs twenty, an oversized substation, a rail spur nobody uses — each is a superadequacy: real cost that a buyer will not reimburse. The gap between reproduction cost and market value is functional obsolescence, and it has to be measured and presented, because no cost table contains it.
Proving economic obsolescence
Economic obsolescence is value lost to conditions outside the property line — a contracted industry, a plant running at a fraction of design capacity, a submarket with more vacant industrial square footage than it can absorb. Assessors resist it because it is external, and external feels speculative to them.
It is measurable. Utilization analysis compares design throughput to actual throughput and scales the shortfall. Market extraction compares what similar industrial buildings actually sell for per square foot against the assessor’s indicated value. Both are standard appraisal technique. The work is assembling production, sales, and market data into a form a board will accept as evidence rather than as argument.
Equipment assessed on both rolls
The line between real property and personal property runs straight through a manufacturing plant, and it moves from state to state. Process piping, dedicated electrical service, machine foundations, dust collection, compressed air distribution, and cranes are treated as realty in some jurisdictions and as personal property in others.
The failure mode is double assessment. The same asset is capitalized into the real property value by the assessor and reported on the personal property statement by your tax department, because neither side is looking at the other. Reconciling the two rolls is one of the more reliable sources of recovery in an industrial portfolio, and it tends to surface pollution control assets that were never certified.

Our plant is assessed near what we spent to build it. Is that wrong?
Usually, though not because the assessor made an arithmetic error. Cost and value diverge the moment construction finishes on a special-purpose facility. You built the plant for what your process requires; the market pays for what a typical industrial buyer requires, and those are different buildings. The difference is functional obsolescence. Where the surrounding industrial market is also soft, economic obsolescence sits on top of it. Neither appears in a cost manual, so neither is in your assessment unless somebody puts it there.
How do you prove economic obsolescence to an assessor?
With data the assessor cannot dismiss as opinion. The two workhorse methods are a utilization study, which compares design capacity against actual production and scales the shortfall into a percentage deduction, and market extraction, which compares recent sales of similar industrial buildings to their reproduction cost to show what the market discounts across the board. Production records, industry capacity data, and submarket vacancy and absorption support both. Presented that way it becomes an appraisal calculation rather than a complaint about the economy.
Is our production equipment real property or personal property?
It depends on the state, and sometimes on the specific asset. Most jurisdictions look at how permanently the item is attached, whether removal would damage the building, and whether it serves the building or the process. Machinery on a poured foundation with dedicated utilities is the hard case. What matters practically is consistency: the asset should appear on one roll, not both. We reconcile the assessor’s property record card against your personal property statement to find items being taxed twice, which is more common than most tax departments expect.
