Definition
Rentable Square Feet is the area used to calculate rent after adding the tenant’s allocated share of common areas to its usable area, according to the applicable measurement method. It is a billing concept and may differ from the space the tenant physically occupies.
Why it matters
This controls contractual rights, billing, obligations, or critical dates. Weak administration can create disputes, missed rights, and permanent NOI leakage.
Owner and investor takeaway
Confirm the lease language, abstraction, calculation method, documentation, and critical dates before accepting a billing, approval, or strategic recommendation.
Staff operating takeaway
Read the executed lease and amendments, abstract the controlling terms, calendar critical dates, preserve backup, and never rely on memory or a generic assumption.
Watch for this
Common mistake
Assuming commercial leases work the same way and applying a standard practice without checking the executed lease, amendments, dates, caps, exclusions, and backup.
