Commercial lease administration is the controlled process of turning executed lease documents into dated operating responsibilities, billing instructions, evidence requirements and decisions. It is not lease interpretation by software or a one-time abstract. The source contract remains controlling, and legal, tax, accounting, building and insurance conclusions remain with the appropriate professionals.
This is general information, not legal, tax, environmental, engineering, accounting or investment advice. Obtain advice specific to the property and transaction.
1. Establish the complete controlling record
Collect the executed lease, offer or agreement to lease where relevant, amendments, renewals, assignments, guarantees, security documents, work letters, plans, measurement records, consents, estoppels and material notices. Record execution status and effective date for each item.
A draft, proposal, unsigned schedule or superseded amendment must not silently populate the operating record. Preserve it separately with an explicit status.

2. Build a clause-cited abstract
Abstract parties, premises, area, use, term, rent, additional rent, deposits, options, insurance, maintenance, capital, assignment, casualty, default, notice and surrender provisions with exact document and section references.
An abstract is a navigation and control tool, not a replacement for the lease or a legal opinion. Record ambiguity and conflicting documents instead of selecting a preferred answer.
3. Convert obligations into accountable workflows
For each recurring or event-driven obligation, identify the responsible party, internal owner, source clause, trigger, due date, required evidence, approval, notice path and escalation. Separate landlord, tenant and shared work.
Do not rely on personal memory or an unowned spreadsheet. Create backups, review rights and a transition process for staff, manager, owner or tenant changes.
4. Reconcile rent, recoveries and tax
Maintain schedules for base rent, escalation, percentage or variable rent, additional rent, utilities, parking, storage and other charges. Reconcile billed, paid, accrued, disputed and adjusted amounts to the source clause and accounting record.
CRA explains that commercial real-property rentals are generally taxable unless an exception applies. Obtain tax advice for actual supplies, invoices, credits and adjustments rather than treating a lease abstract as a GST conclusion.
5. Control property and insurance evidence
Schedule certificates, policies, limits, insured parties, loss-payee or additional-insured evidence, maintenance reports, inspections, permits, licences and repair records required by the lease or operating plan.
An expiry date in a certificate does not prove continuing compliance, and missing evidence does not prove a breach. Verify the contract and escalate through the proper process.
6. Manage changes as controlled transactions
Use a documented intake for assignments, subleases, alterations, expansions, contractions, relocations, renewals, early terminations and ownership changes. Track requested information, consents, conditions, costs, security, notices and signed amendments.
Operational approval, landlord consent, municipal approval and lender consent answer different questions. Do not collapse them into one status.
7. Protect personal and confidential information
Classify tenant financials, guarantees, personal contacts, identification, banking, access credentials and other sensitive records. Restrict access, use secure transfer and keep an access and disclosure record appropriate to the organization.
Alberta's PIPA applies to many provincially regulated private-sector organizations. Privacy scope, authority, safeguards, retention and breach response require organization-specific review.
8. Review exceptions and escalate correctly
Run periodic exception reports for missing documents, upcoming dates, unpaid or disputed amounts, expired evidence, unresolved work and inconsistent records. Assign each item to brokerage, legal, accounting, tax, insurance, engineering, property-management or operational review as appropriate.
