Small Bay Industrial & Flex Space: The Cincinnati FAQ
"Small bay industrial," "flex space," "flex industrial," "multi-tenant industrial," "contractor garage." Brokers, developers, and tenants use these terms constantly, often for the same building, and sometimes for different ones. This page answers the questions we hear most, with Cincinnati-specific numbers wherever we have them. Looking specifically for contractor garage space? Jump straight to our contractor garages page.

What is small bay industrial space?
Small bay industrial space is multi-tenant industrial property divided into individual units, most commonly 1,000 to 10,000 square feet each, with the whole building typically under 50,000 square feet. Each unit pairs a warehouse bay with a small office, usually 5% to 10% of the unit, and a grade-level or dock-high door. Tenants tend to be locally run businesses, trade contractors, light manufacturers, and distributors rather than large national credit tenants.
In Cincinnati, this product sits in a tight market. Metro-wide industrial vacancy was 4.5% in Q2 2026 with 2.10 million SF of positive net absorption, and small-bay product specifically is very likely tighter than that headline number, since it's the segment developers build least.

What's the difference between flex space and small bay industrial?
Flex space and small bay industrial often occupy the same physical buildings but are optimized for different things. Flex space is built for adaptability, with a higher office ratio (roughly 10% up to 50% or more) and finished interiors for a mixed tenant base. Small bay industrial is built for operational efficiency, with a leaner office component (typically 5% to 10%) aimed at trades, logistics, and light manufacturing.
The two terms get used interchangeably in listings and conversation because the underlying shell (a single-story building with roll-up doors and a mix of warehouse and office space) is often identical. What changes is the finish level and the tenant profile a landlord is chasing.

What is a flex office warehouse?
A flex office warehouse is a multi-tenant industrial building where each unit combines warehouse space with a finished office component, all under one roof alongside similar units. The office ratio varies by operator, from as lean as 5% to 10% up to more office-forward configurations.
Locally, Trowbridge Development markets its Cincinnati product as "Flex Office Warehouses" built at roughly 12,000 SF per building, split into 8 units of 1,500 SF each, with office space kept under 10% of each unit, closer to the lean, operationally focused end of the flex spectrum.

What is flex industrial space?
Flex industrial is one of several names used for the same underlying product as small bay industrial and flex office warehouse. Depending on the market and the broker, you'll hear flex industrial, small bay light industrial, and multi-tenant industrial used to describe the same style of building. The terminology hasn't fully standardized across the industry, which is part of why this page exists.

Is a contractor garage the same thing as small bay industrial?
A contractor garage is the smallest, leanest version of small bay industrial: a bare-shell, unheated bay of roughly 750 to 1,500 square feet, sized for a truck and trailer, with no restroom or office buildout. It is a category of industrial real estate, not a company that builds residential garages. See our full contractor garages in Cincinnati page for specs, local comps, and availability.
What is multi-tenant industrial?
Multi-tenant industrial is the broadest of these terms: any industrial building leased to more than one tenant, from small bay projects with 1,000 square foot units up to large distribution buildings split among a handful of major tenants. Small bay industrial is the most common form multi-tenant industrial takes in Cincinnati's core suburban submarkets.
What size is a typical small bay warehouse unit?
Individual small bay units generally range from 750 to 1,500 square feet at the lean, bare-shell end up to 5,000 to 10,000 square feet at the flex or light-industrial end. A full small-bay building or development typically totals between 12,000 and 200,000 square feet, split into 20 to 200 individual units.

How much office space is included in a flex or small bay industrial unit?
Small bay industrial units typically run 5% to 10% office. Flex space units run higher, anywhere from 10% up to 50% or more, depending on the operator and the tenant mix a project targets.
Cincinnati's small-bay product tends toward the lean end: local operators building here keep office space under 10% of each unit.

What kind of tenants lease small bay and flex industrial space?
The most common tenants are trade contractors such as HVAC, plumbing, electrical, and landscaping businesses, light manufacturers and assemblers, e-commerce and last-mile delivery operators, auto repair and detailing shops, and small distribution or logistics firms. This diversity is a structural advantage for owners: a multi-tenant small-bay property spreads risk across many small leases instead of depending on one or two large tenants.
Is small bay industrial a good investment in Cincinnati?
Current fundamentals favor it. Metro industrial vacancy sits at 4.5% with lease rates at $6.51 per square foot per year, the highest since 2023, while Ohio industrial land averages $52,357 per acre, less than half the national average of $117,951 per acre. Combined with thin dedicated small-bay supply, this is an active area for acquisition and development.

Where can I find small bay industrial or flex space for lease near Cincinnati?
The tightest activity is currently in West Chester, Liberty Township, Mason, and Fairfield on the Butler and Warren County side, and in Queensgate, Blue Ash, Sharonville, and Evendale on the Hamilton County side. Each submarket has a different tenant profile and access pattern. See our submarket-by-submarket guide for details on each, plus current listings and off-market opportunities.
What's the difference between a Modified Gross lease and a NNN lease?
In a NNN (triple net) lease, the tenant pays base rent plus property taxes, insurance, and common area maintenance, so the landlord's income is "net" of those costs. In a Modified Gross lease, base rent runs somewhat higher and covers some or all of those operating expenses, with the exact split negotiated between landlord and tenant, often using a base-year expense stop to protect the landlord from expense growth in later years.
For an owner deciding how to lease a small-bay building: NNN shifts expense risk to tenants and is more common in single-tenant or larger investment-grade deals. Modified Gross is more common in multi-tenant small-bay buildings, since it's simpler for smaller trade-business tenants who don't want to manage a separate NNN reconciliation each year, at the cost of the landlord carrying more expense risk inside the base rent.

What is cost segregation and does it apply to small-bay industrial?
Cost segregation is a study that allocates a building's total cost among its components, land improvements, certain building systems, and the structure itself, for depreciation purposes. Components with shorter depreciable lives can sometimes be depreciated faster than the building as a whole, which is the general appeal of the study.
This can apply to small-bay industrial and contractor garage buildings, but whether it makes sense, and what the actual benefit would be, depends entirely on your specific tax situation, how long you plan to hold the property, and your basis. This is general orientation, not tax advice. Grady's background is in accounting and finance, not tax law; talk to your own CPA or tax advisor about whether a cost segregation study is worth commissioning for a specific purchase.

What is a 1031 exchange and how does it work with small-bay property?
A 1031 exchange lets an owner defer capital gains tax on the sale of business or investment real estate by reinvesting the proceeds into like-kind replacement property, under rules in IRC Section 1031. Real estate is broadly like-kind to other real estate, so a small-bay building can generally be exchanged for another small-bay building, a different industrial property, or another qualifying investment property type.
The mechanics carry strict, non-extendable deadlines: you generally have 45 days from closing on the sold property to formally identify replacement property in writing, and the exchange must close within 180 days of that sale. The transaction has to run through a qualified intermediary; you can't take control of the sale proceeds yourself without disqualifying the exchange.
This is general orientation on how the mechanism works, not tax advice for your specific situation. Talk to your CPA or a qualified intermediary before relying on 1031 treatment for a transaction.
