An address and building size are not an asset description. A useful small-bay asset passport explains how the property actually works: its suite mix, office finish, clear height, doors, power, parking, yard, circulation, permitted uses, and the activities taking place behind each bay door.
Two 75,000-square-foot industrial buildings can sit a block apart, share the same zoning label, and be almost nothing alike.
One might be thirty 2,500-square-foot bays with grade-level doors, modest offices, and a fenced yard. The other might be one open box with two docks, substantial power, and nowhere to park a contractor’s fleet.
Same square footage. Different tenant pool, leasing model, management burden, rollover concentration, and probably a different buyer.
That is why I want an asset passport before I rely on the investment memo.
What is a small-bay asset passport?
An asset passport is a working description of how the property functions. It does not replace the leases, survey, plans, property-condition review, zoning analysis, engineering, or site visit. It tells you what those documents and inspections need to answer.
For small-bay, the passport has four parts:
- Space: suite configuration, size mix, frontage, and office flexibility.
- Function: clear height, doors, power, utilities, and life-safety systems.
- Site: parking, yards, loading, circulation, paving, drainage, and security.
- Use: what is permitted and what tenants are actually doing.
The address tells you where the asset is. The passport tells you what you are buying.
Why does the usual property description fall short?
Most public records were designed to identify and tax real estate, not explain how a business park operates. A marketing package may add photographs and a rent roll, but the description still tends to begin—and sometimes end—with the shell: address, building area, year built, land area, and a broad use label.
Those facts matter. They simply do not finish the job.
A 75,000-square-foot park may contain thirty suites or twelve. The office finish may be useful, removable, or so heavy that it narrows the tenant pool. Power may be substantial at the building but unavailable where the next tenant needs it. A yard may look obvious from an aerial while drainage, fire lanes, access, or legal-use restrictions make it impractical.
“Industrial tenant” is equally incomplete. A cabinet maker, plumbing contractor, custom-car business, light manufacturer, gym, gymnastics facility, martial-arts school, church, and professional-services firm place very different demands on the property.
The point of the passport is not to make incomplete information look bad. It is to make unanswered questions visible early enough to close them.
What should the space section record?
Start with the actual suite configuration—not an average created by dividing the building area by a reported unit count.
Count the physical suites. Record each suite’s usable area, frontage, depth, entrance, restroom, meter, loading position, and connection to neighboring bays. Note spaces that are vacant, occupied, shared, or combined informally. Then ask which bays can realistically combine or divide.
Thirty 2,500-square-foot suites create a different operating business than six 12,500-square-foot suites. The first may mean more leases, more turnovers, and a broader pool of local businesses. The second places more income behind each expiration and may serve a narrower tenant group. Neither arrangement is automatically better. They require different leasing, reserves, staffing, and exit assumptions.
Office finish deserves the same suite-level treatment. Record what the “office ratio” actually represents: finished office, showroom, conditioned work area, mezzanine, or an area counted twice. Ask whether the layout helps likely tenants and whether it can change without relocating plumbing, HVAC, electrical service, or the suite’s only restroom.
The space passport should answer:
- How many rentable suites physically exist today?
- What are the actual sizes and realistic re-demising options?
- Which suites can combine, divide, or share access?
- What office finish exists in each suite, and how flexible is it?
- Are utilities, restrooms, addresses, and entrances independently usable?
- Does the lease plan match the physical plan?
What makes a suite functionally useful?
Small-bay tenants do not rent square footage in the abstract. They rent a place where a specific operation can work. Clear height, loading, and power form the functional triangle.
Clear height should be measured to the lowest relevant obstruction, not merely the roof deck. Beams, sprinklers, lights, ducts, and tenant equipment can change what is usable.
Doors and loading should be recorded by suite. Count dock-high and grade-level doors, then note their size, condition, approach, apron depth, and whether parked vehicles or another tenant’s operation block access.
Power should be verified where it will be used. A large building service does not prove that every bay has the right voltage, amperage, or phase. Record the panel, meter, transformer, practical upgrade path, and any special requirements with qualified electrical help.
The function section should also cover sprinklers, alarms, fire separations, gas, HVAC, plumbing, and ventilation. These systems often decide whether the next use needs modest work or a major project.
How should parking, yards, and circulation be evaluated?
The building can work perfectly while the site fails the tenant.
Parking is not just a count. Identify who competes for the spaces and when: employees, customers, work vans, trailers, deliveries, and neighboring tenants. A contractor may need fleet parking before sunrise. A gym, church, or recreation user may create short, intense peaks. A customer-facing business may need the spaces closest to the door.
A visible yard is not automatically a usable yard. Separate three questions:
- Physical: Is the area large, surfaced, drained, fenced, secure, and accessible enough?
- Legal: Are fleet parking, trailers, equipment, and outdoor storage allowed?
- Operational: Can the area work without blocking loading, fire lanes, circulation, or another tenant?
Then walk the complete circulation path from the public street to the loading position and back out. Look at curb cuts, gates, stacking, turning radii, truck-court depth, grades, overhead obstructions, parked vehicles, paving, drainage, lighting, and security.
The useful test is simple: can the likely tenant arrive, park, receive, load, stage equipment, and leave without negotiating around another tenant’s business?
Why is zoning only the beginning of the use question?
A zoning label identifies a district. It may not settle a specific activity.
The use section should examine permitted, conditional, and prohibited uses; overlays; parking requirements; outdoor-storage standards; hours; noise; signage; life-safety implications; prior approvals; and private restrictions. If the operation depends on legal nonconforming status, understand what vacancy, abandonment, casualty, expansion, or a change of use could do to that protection.
Then learn what the tenants actually do. A name or broad industry code may not describe the activity inside the suite. Ask about deliveries, vehicles, customer traffic, storage, equipment, waste, noise, odors, and operating hours. Compare those observations with the lease, certificate of occupancy, permits, and approved uses.
That wider tenant universe is a strength of small-bay. It is also why “industrial tenant” is not enough information to manage the mix.
How should uncertainty be recorded?
Every important field should carry an evidence status:
- Confirmed: supported by the appropriate document, authoritative source, or professional review.
- Observed: visible during a site visit, in current imagery, or through a tenant conversation, but not yet fully documented.
- Unverified: reported, inferred, or still unanswered.
Put the source and date beside the status. A field can move from unverified to observed to confirmed as diligence progresses.
This is useful precisely because it is not scientific theater. The label prevents a broker comment, tenant statement, or visual assumption from quietly turning into a permanent “fact” in the model.
What belongs on the one-page passport?
Use five columns for every field:
Answer | Source | Source date | Confirmed / Observed / Unverified | Next step
Then build the record around these questions:
| Section | Fields to capture | |---|---| | Space | Suite count, actual size mix, combination/division options, office ratio, entrances, restrooms, addresses, utility separation | | Function | Clear height, dock-high and grade-level doors, voltage/amperage/phase, sprinklers, gas, HVAC, plumbing, ventilation | | Site | Employee/customer/fleet parking, yard utility, outdoor storage, truck paths, paving, drainage, lighting, fencing, security | | Use | Permitted and conditional uses, overlays, prior approvals, private restrictions, actual tenant activities, conflicts | | Documents | Rent roll, leases, plans, survey, zoning material, permits, certificates of occupancy, condition review, dated photographs |
If the passport cannot answer a question, do not hide the blank. Assign the next step, the person responsible, and the date it must be closed.
Frequently asked questions
Is an asset passport the same as a property-condition report?
No. A property-condition report focuses on physical condition. The passport connects physical condition with suite configuration, tenant activity, site operation, legal use, and evidence status.
Who should create the passport?
The buyer, owner, or operating team should own it, using information from brokers, tenants, plans, leases, public records, consultants, and site visits. No single source will answer every field.
When should it be updated?
Update it when suites combine or divide, tenants change, building systems are modified, approvals change, or better evidence replaces an assumption.
Does a blank field mean the asset is bad?
No. It means the underwriting has an unanswered question. The purpose of the passport is to make that question visible and assign the next step.
Key takeaways
- An address and building size identify a property; they do not describe how it works.
- Suite configuration, office finish, loading, power, parking, yards, and permitted use belong at the bay level.
- Tenant activity should be understood operationally, not only through a business name.
- Every material field should be labeled confirmed, observed, or unverified.
- A one-page passport should end every unknown with an assigned next step.
