Rent Per Square Foot — Definition & How to Compare Listings

Definition

Rent per square foot is the standard unit used to quote and compare commercial rent, expressed as a dollar amount per square foot, typically on an annual basis for industrial space (e.g., $8.50/SF/year). This standardized unit allows tenants to compare pricing across buildings of different total sizes on a consistent basis.

Annual vs monthly quoting conventions

Convention	Common in
Annual ($/SF/year)	Industrial and warehouse space (standard convention)
Monthly ($/SF/month)	Sometimes used in office or retail markets

What to watch for before committing

Annual vs monthly confusion

Always confirm whether a quoted rate is annual or monthly, since misreading this distinction leads to significant cost miscalculation.

NNN, gross, or other structure clarity

Confirm what lease structure the quoted rent per square foot represents, since NNN, gross, and modified gross figures aren't directly comparable.

Square footage basis

Verify whether the rate applies to usable, rentable, or gross square footage, since this affects your true total cost.

Effective vs base rent per square foot

Distinguish between quoted base rent per square foot and your true effective rent per square foot after accounting for concessions.

Market comparability

Compare quoted rates against recent comparable transactions in the same submarket rather than relying on the asking figure alone.

Escalation impact on per-square-foot cost

Remember that rent per square foot typically increases over the lease term due to escalations, not remaining flat.

Frequently asked questions

How is rent per square foot typically quoted for industrial space? +

Industrial rent per square foot is typically quoted on an annual basis, such as $8.50 per square foot per year, as the standard convention in warehouse leasing.

Is rent per square foot the same as my total occupancy cost? +

Not necessarily — confirm whether the quoted figure is NNN, gross, or another structure, since NNN rates exclude pass-through costs like taxes, insurance, and CAM that add to your true total occupancy cost.

How do I calculate total annual rent from a per-square-foot rate? +

Multiply the quoted rate by your total square footage — for example, $8.50 per square foot times 50,000 square feet equals $425,000 in annual base rent.

Does rent per square foot stay the same throughout my lease? +

Usually not — most leases include an escalation clause that increases rent per square foot annually, so the rate you pay in year five is typically higher than in year one.
