Which Business Categories Are Most Common in Small-Bay Parks?

The Question Every Operator Eventually Asks

You're underwriting a 40-unit small-bay park in a secondary Sun Belt market. Occupancy is 94%. The rent roll looks clean. But when you dig into the tenant list, you see a patchwork of business names that tell you almost nothing: LMG Holdings, Precision Works LLC, South Side Contractors, Creative Studio 7.

Who are these people? What do they actually do? And more importantly — what does the category of tenant tell you about lease durability, rollover risk, and long-term demand?

This isn't an academic question. The business category of your tenants is one of the most underused signals in small-bay underwriting. It tells you how sticky a tenant is, how sensitive they are to economic cycles, how much capital they've sunk into their space, and how easy — or hard — they'll be to replace if they leave.

SpanVor tracks 1,236,000 commercial and industrial properties nationwide, with a core focus on 5,000–250,000 SF small-bay industrial assets. Across that data set, we've built a clear picture of which business categories actually fill these parks — and what that composition means for operators and investors.

Here's what the data shows.

Why Tenant Category Actually Matters

Most small-bay parks are marketed with occupancy rates and weighted average lease terms. Both matter. But neither tells you who is in the building — and who is in the building determines whether your occupancy rate is real or fragile.

Consider two parks, both 95% occupied:

• Park A is filled with skilled trades contractors — HVAC, electrical, plumbing, general contractors. These businesses need a physical base of operations. They store equipment, park vehicles, run dispatch, and receive materials. Moving is expensive and disruptive. They tend to renew.

• Park B is filled with light manufacturers and creative studios. Some of those tenants are growing into larger spaces. Some are one bad quarter from downsizing. The capital they've sunk into their space varies wildly.

Same occupancy rate. Very different risk profiles. Tenant category is what separates them.

The goal of this analysis is to give operators a clear-eyed view of what's actually inside most small-bay parks — and how to think about it.

The Core Tenant Categories in Small-Bay Industrial

Based on SpanVor's analysis across our tracked property universe, small-bay parks are dominated by a relatively consistent set of business categories. The mix shifts by market and submarket, but the recurring categories fall into roughly six buckets.

1. Skilled Trades and Home Services Contractors

This is consistently the largest occupancy category across small-bay parks nationally. HVAC companies, plumbers, electricians, roofers, flooring installers, painting contractors, landscaping firms — these businesses are the backbone of small-bay occupancy.

What makes them ideal tenants:

• They need dedicated, secure space for tools, vehicles, and materials
• They operate from fixed locations and build local routing efficiencies around their address
• Their business model doesn't translate to remote work or shared space
• Owner-operated businesses in this category often develop personal relationships with landlords, increasing renewal likelihood

This category has also been structurally reinforced by the skilled labor shortage — more contractors are expanding their footprint, not contracting it, as demand for home services and commercial build-outs outpaces supply of qualified workers.

2. Light Manufacturing and Fabrication

The second most common category includes businesses doing physical production at small scale: custom metal fabrication, woodworking and cabinetry, sign-making, industrial equipment repair, small-batch food production, printing, and specialty manufacturing.

These tenants require clear heights, drive-in or dock access, and three-phase power. They also tend to customize their space — adding ventilation, epoxy floors, specialized wiring — which creates switching costs that work in the landlord's favor.

The risk: light manufacturers can be more economically sensitive. A custom fabricator serving the construction industry, for example, will feel a housing downturn before the trades contractor who services existing homes will.

3. Distribution, Last-Mile, and E-Commerce Fulfillment

Small-bay has absorbed a significant slice of the e-commerce and local distribution boom. This category includes last-mile delivery operators, Amazon Flex hubs, regional distributors, local wholesale businesses, and small-scale fulfillment centers for DTC brands.

The explosion in e-commerce returns alone has driven material demand for this tenant type — reverse logistics operators need flexible, affordable space close to population centers. Big-box logistics facilities don't serve this need. Small-bay does.

This category tends to run on thinner margins and shorter lease terms. The tradeoff is that demand is structurally durable — local distribution isn't going away — and turnover in this category is usually absorbed quickly in tight markets.

4. Automotive Services and Fleet Operations

Auto repair, collision shops, detailing operations, mobile fleet maintenance, RV and trailer storage, parts suppliers — this is a consistent presence across small-bay parks, particularly in markets with strong blue-collar employment.

Automotive tenants are operationally sticky. Their equipment is heavy, their buildout is specialized, and relocating a functioning auto shop is genuinely difficult. They tend to be long-tenure tenants who renew repeatedly.

The underwriting consideration: automotive uses can create environmental liability if not managed properly. Operators need to stay current on inspection requirements and lease language around hazardous materials.

5. Construction and General Contractors

Distinct from the trades sub-specialty businesses, general contractors — GCs managing multi-trade projects — are a significant presence in small-bay parks in growth markets. They need staging space for materials, secure storage for equipment, and administrative capacity for their crews.

This category is highly correlated with local construction activity. In Sun Belt metros with sustained permitting volumes, GC demand for small-bay space has remained elevated. In markets where construction activity has cooled, this tenant type represents more near-term rollover risk.

6. Professional and Creative Services Requiring Industrial Space

The smallest but growing category: architects, photographers, videographers, artists, designers, personal trainers running private gyms, and other professional service businesses that need more square footage or different physical characteristics than traditional office space provides.

This category has grown as suburban office markets softened and flex industrial became a competitive alternative — lower cost per square foot, more flexible configurations, and the ability to accommodate equipment that wouldn't work in a Class B office suite.

Tenant durability here is variable. The business model doesn't always require the specific space they're in, which means their renewal calculus is more price-driven than operationally driven.

What Category Mix Tells You About a Park

No single tenant category is inherently good or bad. What matters is the composition of your park's tenant mix and whether that composition is intentional or accidental.

High trades and automotive concentration = operationally sticky, economically resilient in most cycles, but potentially constrained in rent growth if you're serving owner-operators with fixed margins.

High light manufacturing concentration = higher potential for tenant improvement investment and longer initial leases, but more economic sensitivity and longer re-tenanting timelines if a tenant fails.

High distribution/fulfillment concentration = structurally durable demand, faster velocity of lease-up after turnover, but shorter average lease terms and thinner tenant financial profiles.

Mixed-use category parks = the most common profile, and generally the most resilient. A park with representation across trades, light manufacturing, and distribution is less exposed to a single sector downturn.

Operators who understand their category mix can make targeted decisions: which tenant types to prioritize in lease-up, where to invest in buildout, and which markets have category-specific demand gaps worth targeting.

Practical Takeaways for Operators and Investors

1. Audit your existing roll before you close. Don't just review the lease terms. Identify the category of each tenant. Assign each one to a bucket. Then assess: what percentage of your base rent comes from operationally sticky tenants versus price-sensitive tenants? That ratio matters more than aggregate occupancy in a downturn.

2. Use category mix as a leasing strategy, not just a reporting metric. If you're 30% vacant, what category of tenant fills the remaining space best? Matching tenant category to your space configuration — clear height, power, dock access, parking ratio — is the fastest path to durable occupancy.

3. Think about category concentration risk the same way you think about tenant concentration risk. Just as you'd be wary of having 40% of your base rent from one tenant, be wary of having 70% from one category. If you're a construction-heavy market and permitting craters, category concentration bites.

4. Category is a sourcing signal, not just an underwriting variable. If you're looking for parks to acquire, look at tenant category mix as a proxy for owner sophistication. Parks with diverse, operationally sticky tenant mixes are often better-run — and more valuable. Parks with high turnover in price-sensitive categories may reflect a management problem, a pricing problem, or a market-position problem. All of those are solvable — but only if you spot them first.

5. Match your market to your category thesis. Trades-heavy demand is present in almost every metro. Last-mile distribution demand is concentrated in high-density population centers. Light manufacturing benefits from proximity to industrial workforce pipelines. Before you enter a new market, understand which categories are structurally supported by that market's economy — and which ones you'd be leasing against the grain.

The Data Layer Most Operators Don't Have

The reason tenant category analysis is underused isn't that operators don't care. It's that the data is hard to get.

Most CRE databases track property-level data — square footage, lease comps, sale history. They don't track what the businesses inside those properties actually do. That gap is where deal quality gets obscured and risk gets mispriced.

SpanVor is built to close that gap. Across 1,236,000 commercial and industrial properties, with a focused lens on 5,000–250,000 SF small-bay assets, the platform is designed to give operators the tenant-level intelligence that generic CRE tools don't surface.

That means understanding not just that a park is occupied — but who is occupying it, what category they fall into, and what that composition signals about asset quality, risk, and opportunity.

Bottom Line

Small-bay parks look similar from the outside. Occupancy rates, square footage, and cap rates are the numbers that get reported. But the real signal — the one that separates a durable asset from a fragile one — is the business category composition of the tenant base.

Trades and automotive tenants are sticky. Light manufacturers carry more economic risk. Distribution demand is structurally durable but operationally thinner. Creative and professional services are growing but price-elastic. Mixed-category parks are generally your most resilient assets.

Operators who build their sourcing, leasing, and underwriting around category intelligence don't just make better decisions — they see things that operators relying on surface-level data simply miss.
