A roof, paving, HVAC or life-safety project can create several different records: physical scope, invoice, accounting treatment, insurance treatment and lease allocation. None alone answers what a tenant owes. The executed lease, amendments, project evidence and professional conclusions must be analyzed together.
This is general information, not legal, tax, environmental, engineering, accounting or investment advice. Obtain advice specific to the property and transaction.
1. Define every relevant lease category
Abstract operating costs, maintenance, repair, replacement, capital expenditure, structural work, common areas, premises work, tenant-specific work, ownership costs, management and amortization. Identify inclusions, exclusions and exceptions.
Do not assume net or triple net resolves the question. Broad lease labels still require clause-level analysis.
- Physical scope
- Lease definition
- Accounting treatment
- Recovery method
- Allocation
- Useful period
- Evidence
2. Build the project source file
Collect condition reports, failure evidence, specifications, bids, contracts, change orders, invoices, completion records, warranties, insurance, grants and dates placed in service. Separate emergency stabilization from permanent work.
A single invoice description such as repair or replacement does not establish technical scope, accounting classification or lease recovery.
3. Separate maintenance, repair, replacement and improvement
Document the component condition before work, the problem addressed, the extent removed, the resulting capacity or life, and whether the project serves the building, premises or a particular tenant.
Technical, accounting and legal professionals may classify the same project for different purposes. Keep those conclusions distinct and identify who made each one.
4. Identify structural and ownership exclusions
Map financing, depreciation, ground rent, leasing commissions, tenant inducements, initial construction, structural defects, code violations, casualty, negligence, environmental work and other ownership categories to the actual lease.
A cost incurred by the landlord or benefiting the property is not automatically recoverable. An exclusion may also contain a specific exception requiring separate calculation.
5. Analyze permitted amortization transparently
If the lease permits capital recovery, record the eligible basis, deductions, placed-in-service date, useful or recovery period, rate, annual amount, affected categories and allocation. Show the property actual separately from the tenant charge.
Ontario's Wheelhouse Coatings decision illustrates how express amortization language can matter. It does not decide an Alberta lease, project classification or recovery period.
6. Reconcile insurance, warranties and third-party recovery
Identify insurance proceeds, deductibles, warranty payments, grants, rebates, vendor credits and amounts recovered from a specific tenant or other source. Test whether the lease requires deductions or special treatment.
Avoid duplicate recovery and preserve timing differences. A receivable or pending claim should not be treated as cash received without explanation.
7. Allocate the permitted amount
After contract and accounting review, apply the correct premises area, denominator, period, direct allocation, cap, gross-up or other rule. Track tenant shares and effective dates where occupancy changes.
Do not apply a building-wide percentage to a project serving only one component without evidence and lease support.
8. Preserve the owner and tenant explanation
The final record should show the project, source cost, deductions, lease clause, professional conclusions, permitted recovery, calculation, invoice, GST treatment and remaining balance. Record questions and corrections by version.
Commercially does not classify capital expenditure, interpret the lease, certify building work or determine recoverability. Use counsel, accounting and technical advisors for the actual property.
