What Defines Small-Bay Industrial?
Small-bay industrial is a commercial real estate asset class characterized by multi-tenant buildings with compact, flexible units. Unlike traditional big-box warehouses serving single large occupiers, small-bay properties divide space among 20–100+ tenants, each occupying units typically ranging from 500 to 10,000 square feet.
These properties are sometimes called "contractor bays" or "service bays" because of their popularity with trade contractors and local service businesses. See our complete list of 17 names for this asset class.

The Bottom Line
Small-bay industrial is a multi-tenant industrial format built around compact units, short leases, and a local tenant base. Diversified income, frequent rent resets, and limited new supply are the usual reasons owners and investors underwrite it. Results still vary by market, vintage, and lease structure.
For tenants, the format offers right-sized warehouse-office space close to customers, often with grade-level access and enough yard space to run a trade or light distribution operation.
