Commercial Lease Area Measurement and BOMA Evidence in Alberta

1. Freeze the proposal denominator

Record the area in the listing, proposal, offer, draft lease and final lease. For each, identify whether it is estimated, represented, measured, rentable, usable, gross, leasable or another defined term and whether storage, mezzanine, patio or other areas are included.

Do not compare rates before converting proposals to the actual annual and monthly cash produced by their respective denominators.

• Premises exhibit
• Area term
• Standard and edition
• Method and preparer
• Charge definition
• Remeasurement clause

2. Identify the exact standard

BOMA's current standards page lists distinct property-type publications and earlier editions. Record the full standard name, identifier or edition and any selected method rather than inserting a generic BOMA reference.

BOMA states that its standards do not direct which methodology the parties must choose; the stakeholders generally choose the lease basis. Counsel and the measurement professional should align the clause with the intended calculation.

3. Obtain the complete area package

Request the dated plan, measurement report, area chart, allocation schedule, assumptions, exclusions, property-type classification and preparer credentials or scope. Confirm whether the work covers the whole building, a partial measurement or only one premises.

A single certificate number or plan total may not reveal the edition, method, common-area allocation or changes made after measurement.

4. Trace shared-area allocations

Identify floor, building, inter-building, amenity or mixed-use allocations applicable under the chosen method and show how they reach the premises. Keep parking, storage and separately licensed areas visible rather than embedding them without explanation.

A ratio calculated from two headline numbers is only a screening relationship. Do not label it an official BOMA load factor unless the qualified report and applicable standard support that terminology and calculation.

5. Model the complete cash effect

Apply base rent, escalation, additional rent, taxes, utilities and any other area-based charge to the lease-defined area. Then model the same proposal under each unresolved area record to expose the annual and term sensitivity.

A measurement difference can affect more than base rent. Review the lease definitions for proportionate share, operating costs, tax allocation, caps, gross-up and management fees.

6. Control construction and premises changes

Address measurement after landlord work, tenant work, subdivision, expansion, contraction, building additions, amenity changes and mixed-use reconfiguration. State the responsible preparer, timing, access and document delivery.

A later measurement should not automatically rewrite economics unless the agreement provides the mechanism. Counsel should address thresholds, notice, dispute process and retroactive or prospective treatment.

7. Preserve verification and dispute rights

Define the period to review the area package, who may remeasure, the standard and edition to use, reliance and certification requirements, cost responsibility, dispute resolution and the evidence that controls pending resolution.

A brokerage comparison can identify financial sensitivity but cannot decide which lease interpretation is legally correct or whether a measurement complied with a proprietary standard.

8. Deliver one controlled premises record

Attach the final premises plan and area schedule to the lease or controlled transaction file, identify superseded versions and preserve subsequent changes. Connect area to rent commencement, possession and delivery evidence without confusing it with municipal permission to occupy.

Commercially coordinates licensed commercial real estate search, marketing and transaction evidence. It does not perform a BOMA or other certified measurement, select a contractual measurement method, interpret a lease, survey boundaries, determine code capacity or provide architectural, engineering, appraisal, accounting, tax or legal advice. Commercially can coordinate leasing options and evidence requests, but the parties and their professionals control the measurement and lease result.
