A Class A warehouse is a designation for the newest, highest-specification tier of industrial buildings in a market, typically built within the last 10–15 years with modern clear height, dock ratios, and construction standards. Class A buildings usually occupy prime logistics locations near highway interchanges and command the top rents in their submarket, reflecting their functional advantages over older Class B and C inventory.
Typical Class A specifications
| Specification | Typical Class A range |
|---|---|
| Clear height | 32–40+ ft |
| Building age | Built within last 10–15 years |
| Dock ratio | 1 door per 3,000–8,000 SF |
| Column spacing | 50×50 ft or wider |
| Location | Near major highway interchanges |
Class A vs Class B/C: what changes
Class designation isn't officially standardized, but market convention generally reserves "Class A" for buildings combining modern construction, high clear height, ample power capacity, and strong highway access. Class B buildings are typically older or have moderate specifications, while Class C buildings are the oldest or most functionally obsolete tier, often with lower clear heights and limited dock capacity.
What to watch for before committing
Subjective classification
Class designations aren't standardized across brokerages — always verify actual specifications rather than relying on the label alone.
Rent premium justification
Confirm the Class A premium is justified by your specific operational needs, since Class B space may suffice at meaningfully lower cost.
True clear height verification
Even in a marketed Class A building, confirm actual usable clear height rather than assuming the marketing figure is accurate.
Market-specific standards
What counts as Class A in one market may only be Class B in a more mature, higher-spec market — compare within the same submarket.
Availability and competition
Class A space in tight markets often leases quickly — be prepared to move fast if you find a fitting building.
Future obsolescence risk
Today's Class A specifications become tomorrow's Class B as new construction raises the bar — factor this into long-term investment decisions.
