Ask ten people how many types of industrial real estate exist and you’ll get ten different answers. Some will say three. Others will say eight. The honest answer is that it depends on how granular you want to get, but the businesses searching for space rarely care about the label. They care about whether a building will actually work for what they do.

Why the Category Matters

Industrial real estate is a broad term that covers a wide range of building types, and each one is shaped by how it’s actually used. A property that’s ideal for one operation can be completely unworkable for the next, even when both are labeled “industrial” on a listing sheet. Clear height, power capacity, dock configuration, and zoning all vary by category, and getting the wrong one under lease can be a costly mistake to unwind.

In Southern Arizona, where aerospace and defense manufacturing, optics and photonics, bioscience, mining, renewable energy, and logistics companies are all competing for space, matching the building to the business is the whole game. Below are the three broad categories and seven specific building types worth knowing before you start a search.

Category 1: Manufacturing Properties

Manufacturing properties are used to produce or assemble goods. Because manufacturing activity tends to generate noise, traffic, and specialized utility demands, these buildings carry their own zoning considerations that don’t always map cleanly to a building’s physical type. An experienced tenant representative is worth having in your corner to make sure the space you choose is actually permitted for what you plan to do in it.

Not every manufacturing operation has the same footprint. Producing precision optics is a very different undertaking than assembling steel fabrications, which is why this category splits into two working subtypes.

1. Heavy Industrial Buildings

Heavy industrial buildings house the production of goods and materials at scale. Expect heavy-duty equipment, extensive machinery, three-phase power, and ample employee parking. These properties are also commonly built with reinforced HVAC systems, air lines, floor drains, and high-volume water supply to support specialized production processes.

Some heavy industrial uses, due to noise, emissions, or general nuisance, are further restricted to specific zoning districts and buffered from neighboring properties.

Where You’ll See This in Southern Arizona

• Component fabrication and assembly supporting the region’s aerospace and defense supply chain
• Precision optics and photonics production requiring heavy power and specialized cleanroom-adjacent space
• Mining equipment fabrication, repair, and staging tied to Southern Arizona’s copper and mineral operations
• Solar and renewable energy equipment manufacturing

2. Light Manufacturing / Assembly

Light manufacturing and assembly buildings still handle the manufacture or assembly of goods, but without the extent of specialized infrastructure heavy industrial users require. These properties generally need less energy, less vertical clearance, and fewer built-in improvements, which also makes them easier to re-lease to a new tenant down the road.

Where You’ll See This in Southern Arizona

• Precision component assembly for aerospace and defense subcontractors
• Solar panel and renewable energy component assembly
• Medical device and bioscience instrument assembly
• Contract packaging and light product assembly for regional distributors

Category 2: Warehousing and Distribution Properties

Warehouse and distribution properties exist to store and move raw materials and finished goods rather than produce them. Office build-out in these buildings is typically modest, often under 15% of total square footage, with the balance dedicated to storage, staging, and loading.

3. Distribution Centers

Distribution centers are built with tall clear heights because these users measure efficiency in cubic volume, how much product they can stack vertically, rather than footprint alone. They’re also built with a high ratio of dock doors to accommodate frequent semi-truck loading and unloading, serving as the intermediate step between manufacturing and final delivery. This is the building type most people picture when they hear “industrial real estate.”

Where You’ll See This in Southern Arizona

• Regional distribution supporting retail and e-commerce fulfillment across the Southwest
• Parts and inventory staging for manufacturers along the I-10 and I-19 corridors
• Cross-border trade and nearshoring-driven distribution tied to Arizona’s proximity to Mexico

4. Truck Terminals

Truck terminals are technically a form of warehouse, though they’re rarely used for storage. Also called cross-dock facilities, they exist for the fast transfer of goods from one truck to another, with products passing through in hours rather than days or weeks, a critical link in regional and national distribution networks.

Where You’ll See This in Southern Arizona

• Cross-dock operations for regional trucking and freight carriers
• Transfer points supporting cross-border freight movement along Arizona’s trade corridors

5. Cold Storage

Cold storage properties store temperature-sensitive goods such as food or pharmaceuticals. These buildings require superior insulation, advanced HVAC and humidity control, and emergency backup systems to maintain consistent conditions, even during a power outage. As a result, their energy demands tend to run well above those of standard storage and distribution space.

Where You’ll See This in Southern Arizona

• Food and beverage distribution and cold-chain logistics
• Produce and agricultural storage supporting regional agriculture
• Pharmaceutical and bioscience cold-chain storage

Category 3: Flex Properties

“Flex” describes an industrial-zoned property used, in part or in whole, for purposes outside the manufacturing and warehouse categories above. It’s less a precise use type and more of a catch-all for buildings that blend functions.

6. Flex Spaces

Flex properties are exactly what the name suggests: adaptable. They typically combine office space with some mix of assembly, warehousing, distribution, or showroom use under one roof.

Where You’ll See This in Southern Arizona

• Hybrid office, showroom, and light assembly space for growing regional manufacturers
• Specialty trade and contractor operations that pair office space with attached shop or storage areas

7. Research & Development (R&D)

R&D properties serve nearly every industry but are especially common among bioscience and med-tech users. These buildings fall under the flex umbrella but typically carry additional specialized requirements, including clean rooms, high power capacity, and precise HVAC control. R&D space is some of the most niche product on the market, often custom-built or extensively improved for a single tenant.

Where You’ll See This in Southern Arizona

• Bioscience and med-tech research and laboratory space
• Optics and photonics research, testing, and prototyping
• Aerospace and defense engineering and testing facilities requiring cleanrooms or specialized power

Matching Space to Southern Arizona’s Growth Industries

Tucson’s industrial base has grown well past a single definition of “industrial.” The region’s long-standing aerospace and defense manufacturing presence, its concentration of optics and photonics expertise, an active mining and mineral processing sector, an expanding bioscience and biotech research community, and growing solar and renewable energy manufacturing all draw on different combinations of the seven building types above. Add in Tucson’s position along the I-10 and I-19 corridors and its proximity to the Mexico border, and it’s easy to see why distribution and logistics space has become just as competitive as manufacturing space.

It’s also common for a single company’s real estate footprint to blend more than one of these categories, a defense supplier with heavy industrial space for fabrication and a separate distribution building for outbound parts, or a bioscience company with R&D lab space paired with cold storage for sensitive materials. Understanding your full operational need, not just a square footage number, is what makes a real estate search effective rather than a guessing game.

Not Sure Which Type of Industrial Space Fits Your Business?

Commercial Real Estate Group of Tucson represents tenants, users, and buyers exclusively, never landlords or sellers. Whether you need heavy manufacturing space, a distribution center, cold storage, or R&D and flex space, we’ll help you identify the right building type, evaluate options across Southern Arizona, and negotiate terms that fit your operation.
