How Texas Warehouses and Industrial Properties Get Overassessed
Texas has become the epicenter of industrial and logistics real estate in the United States. The state added over 50 million square feet of new warehouse and distribution space between 2022 and 2025, concentrated in DFW, Houston, San Antonio, and Austin. All that new construction is great for the economy — but it’s inflating property tax assessments for existing warehouse owners in ways that don’t reflect reality.
If you own a warehouse, distribution center, flex space, or industrial building in Texas, there’s a strong chance your county appraisal district is overvaluing it. Here’s how it happens, and what the data actually looks like.
The New Construction Problem
This is the single biggest driver of overassessment for Texas industrial properties, and it’s straightforward: appraisal districts use recent sales of comparable properties to determine your building’s market value. When the majority of recent industrial sales are brand-new, Class A distribution centers built for Amazon, FedEx, or major logistics companies, those sale prices get used as comparables for your 1990s-era warehouse with a cracked concrete floor and 24-foot clear height.
The numbers tell the story:
| Property Type | Typical Sale Price/SF (2024-2025) |
|---|---|
| New Class A distribution (36’+ clear, cross-dock) | $125–$175/SF |
| 2010s-era Class B warehouse (28-32’ clear) | $80–$110/SF |
| 1990s-era Class C warehouse (20-24’ clear) | $50–$75/SF |
| Older flex/light industrial (under 20’ clear) | $40–$60/SF |
When an appraisal district pulls “comparable sales” for your 1995-built warehouse and half those comps are new-construction facilities that sold at $140/SF, your assessment gets pulled upward. The mass appraisal model applies adjustments for age and condition, but those adjustments are rarely enough to account for the full gap between new and existing industrial properties.
Specific Ways Industrial Properties Get Overvalued
Clear Height Matters More Than the District Thinks
Modern logistics demands 36-foot clear heights to accommodate tall-rack storage and automation systems. A warehouse with 24-foot clear heights — common in buildings from the 1980s and 1990s — is functionally less valuable for today’s most active industrial tenants. Appraisal districts don’t always apply adequate adjustments for this difference.
I’ve seen appraisals where a 24-foot-clear warehouse in Dallas County was assessed at 90% of the per-square-foot value of a 36-foot-clear facility nearby. The actual market gap is closer to 40-50%.
Dock Configuration and Truck Court Depth
A modern cross-dock facility with 60+ dock doors and 130-foot truck courts commands premium rents. An older warehouse with 8 dock doors and a shallow truck court serves a completely different tenant base at significantly lower rents. Mass appraisal models group these properties by “industrial” use without granular enough adjustments for dock count, truck court depth, and loading configuration.
Functional Obsolescence
Older industrial buildings often have features that reduce their utility for modern tenants: insufficient power capacity for automated systems, column spacing that limits racking efficiency, low office-to-warehouse ratio for e-commerce fulfillment operations, or HVAC systems that can’t support cold chain requirements. These functional obsolescence issues should reduce the assessed value, but appraisal districts rarely account for them without a protest.
Location Within Industrial Corridors
Not all locations within an industrial submarket are equal. A warehouse directly adjacent to an interstate interchange with easy truck access is worth more than one two miles from the highway with residential street constraints. Appraisal districts often apply the same per-square-foot rates across broad industrial zones without accounting for micro-location differences.
The Income Approach Problem
For leased industrial properties, the income approach to valuation should theoretically capture the actual market value based on real rental income. In practice, appraisal districts make assumptions that inflate the value:
Inflated rent assumptions. If the district uses asking rents for new construction rather than actual contract rents for existing space, the income approach overstates value. New Class A industrial space in DFW is leasing at $7-9/SF NNN. Existing Class B space is more like $4.50-6.00/SF. That difference compounds dramatically when you capitalize the net income.
Cap rate compression. Appraisal districts have been using cap rates in the 5.5-6.5% range for industrial properties, reflecting the institutional investor market. But not every warehouse is an institutional-quality asset. A 30-year-old, single-tenant warehouse with a short-term lease should be valued at a higher cap rate (lower value) than a new build with a 10-year credit tenant lease.
| Factor | District Assumption (Typical) | Actual Market (Existing Industrial) |
|---|---|---|
| Asking rent | $7.00-9.00/SF NNN | $4.50-6.00/SF NNN |
| Vacancy rate | 3-5% | 5-12% (varies by submarket) |
| Cap rate | 5.5-6.5% | 7.0-9.0% (for older assets) |
| Operating expense ratio | 10-15% | 15-25% (older buildings cost more to operate) |
When you correct the rent, vacancy, and cap rate assumptions to reflect your actual property, the value difference can be 25-40% lower than what the district assessed.
Where We See the Worst Overassessment
Texas industrial overassessment is concentrated in the markets with the most new construction activity:
DFW Metroplex. The Alliance corridor in Tarrant County, the I-20 corridor in Dallas County, and the I-35E spine through Denton County have seen massive new construction. Existing buildings throughout these areas are getting assessed at values driven by new-build transactions. In 2024, Tarrant County alone saw over 54,000 commercial protests — industrial properties are a huge portion of that.
Houston. The Baytown, Katy, and northwest Houston industrial submarkets have absorbed millions of square feet of new space. Harris County’s HCAD has been aggressive with industrial values.
San Antonio. The Port San Antonio redevelopment and I-10 East corridor in Bexar County have attracted new logistics development that’s pulling up assessments for older industrial properties nearby.
Austin. Highway 130 and eastern Travis County have become industrial hotspots, with Tesla’s Gigafactory development reshaping the area’s comparable sales landscape.
How to Protest Your Industrial Property’s Assessment
The evidence that wins industrial property tax protests is specific and data-driven:
-
Comparable sales of similar-quality buildings. Not just “industrial” — match the clear height, age, dock configuration, and condition. A 1995-built warehouse should be compared to other 1990s-era buildings, not 2024 new construction.
-
Actual income and expense data. If your property is leased, your actual rent roll and operating expenses are the strongest evidence. If it’s vacant or partially vacant, document the actual vacancy and marketing history.
-
Condition documentation. Photos and repair estimates for deferred maintenance, roof issues, HVAC age, concrete condition, and any functional obsolescence.
-
Market rent surveys. Data from CoStar or local industrial brokers showing actual lease rates for comparable buildings in your submarket.
This is an area where having a consultant makes a real difference. We have access to industrial comp databases and understand how to present the income approach in a way that appraisal district appraisers respond to.
The Opportunity Is Real
Industrial property owners in Texas are sitting on some of the largest overassessment gaps we see across any property type. The combination of a construction boom, aggressive appraisal practices, and mass appraisal limitations creates a perfect environment for successful protests.
Our average reduction for industrial and warehouse properties in Texas is between 15% and 25% of assessed value. On a $4 million warehouse, that’s $12,600 to $21,000 in annual tax savings at a typical 2.1% effective rate.
We work on a 30% contingency — first-year savings only, nothing if we don’t reduce your value. The May 15 protest deadline is approaching fast.
