1. Lease Structures & Types
Gross Lease
A commercial lease where the tenant pays a single fixed monthly rent and the landlord absorbs all operating costs — property taxes, insurance, utilities, maintenance, and management fees. Less common in BC commercial markets, occasionally used in older properties or short-term arrangements. Landlords typically build a higher base rent to compensate for absorbed costs.
Modified Gross Lease
A hybrid commercial lease where the tenant pays base rent plus a defined subset of operating costs (often utilities and janitorial), while the landlord covers the rest. The split is negotiated and varies by lease — there is no standard "modified gross" formula. Common in BC for older office buildings and certain industrial properties.
Net Lease (Single, Double, Triple)
A category of commercial leases where the tenant reimburses the landlord for one or more operating cost categories on top of base rent. Single net (N) = tenant pays property taxes. Double net (NN) = tenant pays taxes plus insurance. Triple net (NNN) = tenant pays taxes, insurance, and operating costs. In BC, triple net is by far the most common variation in multi-tenant commercial properties.
Triple-Net Lease (NNN)
The most common commercial lease structure in BC. The tenant pays base rent plus their proportionate share of property taxes, building insurance, and operating costs (CAM). The landlord collects base rent for the use of the space; the costs of owning and operating the building flow through to tenants as additional rent. See our full NNN guide.
Absolute NNN / Bondable Lease
The most landlord-friendly net lease variant — the tenant assumes essentially every cost related to the property, including major structural and capital items (roof, foundation, HVAC replacement). The landlord's role reduces almost to collecting rent. Most common in BC for single-tenant industrial properties or net-leased investment properties where the tenant is creditworthy enough to be trusted with capital decisions.
Percentage Lease
A retail lease where the tenant pays base rent plus a percentage of their gross sales above a defined threshold (the "breakpoint"). Common in Greater Vancouver retail centres and shopping plazas, particularly for anchor tenants and food service. The landlord shares in tenant success; the tenant gets a lower base rent in slow periods.
Ground Lease
A long-term lease (typically 50–99 years) where the tenant leases only the land and constructs or operates a building on it. The tenant owns the improvements during the lease term; at expiry, the building usually reverts to the landlord. In Greater Vancouver, common with First Nations land, municipal sites, and certain institutional landlords.
2. Rent & Financial Terms
Base Rent
The fixed portion of rent a commercial tenant pays for occupying the space, separate from operating cost recoveries. Usually quoted in dollars per square foot per year ($/sf/year) in BC commercial markets. Base rent escalates over the lease term according to a defined formula — fixed steps, CPI indexing, or fair market value resets at renewal.
Additional Rent / TMI (Taxes, Maintenance, Insurance)
The portion of commercial rent paid on top of base rent to cover operating costs. In BC, "TMI" is a common shorthand for the three main categories: property Taxes, Maintenance, and Insurance. Charged monthly as estimated amounts and reconciled annually against actual costs.
Gross Rent
The total amount a commercial tenant pays each month, including base rent and additional rent (TMI). Used as the basis for percentage-of-gross-rent management fee calculations and many other lease calculations. For BC landlords, gross rent is the operationally meaningful figure that flows into financial reporting.
Net Operating Income (NOI)
A property's gross income minus all operating expenses, before debt service, depreciation, and income taxes. The single most important measure of a commercial property's operating performance. In Greater Vancouver, NOI directly drives a property's valuation (NOI ÷ Cap Rate = property value), making operating cost recovery and lease administration discipline financially critical.
Common Area Maintenance (CAM)
The category of operating costs related to maintaining shared areas of a commercial property — parking lots, hallways, lobbies, exterior lighting, landscaping, snow removal, and shared building systems. CAM costs are typically passed through to tenants under net leases as part of their additional rent. See our CAM charges guide for what's recoverable in BC.
CAM Reconciliation
The annual process where the landlord compares actual operating costs against estimated CAM amounts collected from tenants throughout the year, then bills shortfalls or credits overpayments. BC leases typically require reconciliations within 90–180 days of fiscal year-end. A landlord who fails to reconcile on time may lose the right to collect shortfalls.
Operating Costs
The full set of expenses required to operate a commercial property — property taxes, insurance, utilities, repairs, maintenance, janitorial, landscaping, snow removal, security, property management fees, and (depending on lease language) capital expenditures. Under NNN leases in BC, these costs are recovered from tenants as additional rent.
Capitalization Rate (Cap Rate)
The ratio of a property's net operating income (NOI) to its market value, expressed as a percentage (NOI ÷ Value = Cap Rate). Used to value commercial properties: a property generating $200,000 NOI at a 5% cap rate is worth $4M. In Greater Vancouver commercial markets, cap rates vary by asset class and location — typically lower (more expensive) for prime urban retail, higher (less expensive) for suburban industrial.
Gross-Up Provision
A lease clause for multi-tenant buildings that lets the landlord calculate variable operating costs as if the building were fully occupied (typically 95–100%), then bill tenants their proportionate share. Without a gross-up provision, the landlord absorbs the operating cost share attributable to vacant space. Essential for BC multi-tenant landlords managing buildings with vacancy.
Pro Rata Share
The percentage of a building's recoverable operating costs that a tenant pays, calculated as the tenant's leased square footage divided by the total leasable square footage of the property. For example, a tenant occupying 5,000 sq ft in a 25,000 sq ft building has a 20% pro rata share. Used throughout BC commercial leases to allocate CAM, property taxes, insurance, and management fees among tenants.
3. Lease Provisions & Clauses
Renewal Option
A lease clause giving the tenant the right (not the obligation) to extend the lease for an additional term, usually on specified conditions. In BC commercial leases, the notice window is typically 6–9 months before expiry, sometimes up to 12. Courts strictly enforce notice deadlines — a missed deadline almost always means the renewal right expires. See our lease renewal guide.
Right of First Refusal (ROFR)
A lease clause giving the tenant the first opportunity to lease additional space (or buy the property) if it becomes available, on terms a third party has offered. The landlord must present any genuine third-party offer to the tenant before accepting it. Common in BC for tenants wanting to control adjacent space without committing to it now.
Estoppel Certificate
A document signed by the tenant confirming key facts about the lease — term, rent paid, deposits held, default status, and any side agreements. Required by lenders during refinancing and by buyers during commercial property acquisition due diligence. In BC, leases typically obligate the tenant to deliver an estoppel certificate within a defined timeframe upon landlord request.
Quiet Enjoyment
The tenant's right under their lease to use the premises without interference from the landlord or third parties claiming through the landlord. A fundamental implied covenant in BC commercial leases. Breach can occur through landlord actions like withholding access, excessive construction noise, or failing to enforce against other tenants disrupting the property.
Holdover Tenancy / Overholding
The situation that arises when a commercial tenant remains in possession of the premises after the lease term has expired, without a new lease executed. In BC, the holdover is typically month-to-month on the original lease terms, often at an overholding rent of 125–150% of the prior base rent. The landlord can accept this temporarily or give notice to end the month-to-month tenancy.
Permitted Use
A lease clause defining what business activities the tenant may conduct on the premises. Narrow permitted-use clauses protect the property's tenant mix and prevent conflict with other tenants' exclusive-use rights. Broad permitted-use clauses give the tenant flexibility to pivot their business. Common in BC retail leases to prevent direct competition between tenants in the same plaza.
Assignment & Subletting
Lease clauses governing the tenant's ability to transfer the lease to another party (assignment) or rent part of the space to a third party (subletting). Most BC commercial leases require the landlord's written consent — which the landlord cannot unreasonably withhold, but can attach reasonable conditions (financial review of the new tenant, continued personal guarantee from the original tenant).
Tenant Improvement Allowance (TIA / TI)
A landlord contribution toward the cost of build-out, renovations, or fixtures the tenant requires to occupy the space. Usually expressed as dollars per square foot. In Greater Vancouver, TIAs are common in office leases and for new retail tenants — the landlord effectively trades upfront capital for a longer lease term or higher rent.
4. BC Legal & Regulatory
BC Commercial Tenancy Act
The provincial statute governing commercial landlord-tenant relationships in British Columbia. Notably narrower than the residential equivalent — much of what governs commercial leases lives in the lease document itself, not the statute.
BC Strata Property Act
The provincial statute governing strata corporations in British Columbia, including commercial strata. Sets rules for strata bylaws, common property, contributions, special levies, and depreciation reports. Critical for owners of commercial strata units, where the strata corporation's decisions and finances directly affect the unit's value.
BCFSA (BC Financial Services Authority)
The Crown agency that regulates real estate professionals, mortgage brokers, credit unions, and other financial services in British Columbia. All commercial property management firms in BC operating as licensed brokerages report to BCFSA. Sets rules around trust account management, records retention, and the records transfer obligations that apply when switching property managers.
Real Estate Services Act (RESA)
The BC statute that licenses and regulates real estate professionals, including commercial property managers. Establishes rules around trust accounts, record-keeping, conflict-of-interest disclosure, and the duties owed to clients. Enforced by BCFSA. Sets the framework that every licensed BC commercial property management firm operates under.
Property Transfer Tax (PTT) — BC
A provincial tax payable by the purchaser when property changes hands in BC. Tiered structure: 1% on the first $200,000 of fair market value, 2% on the portion between $200,000 and $2M, 3% on the portion above $2M, plus an additional 2% on the residential portion above $3M (where the property includes residential use). Commercial properties in Greater Vancouver commonly exceed these thresholds — a $10M commercial purchase carries roughly $278,000 in PTT. Property managers should be aware of PTT when advising owners on acquisitions or when timing a management transition around a sale.
BC Assessment
The Crown corporation that determines the property tax assessment value of every property in British Columbia annually. The assessed value drives property tax calculations but is not the same as market value or replacement cost. BC commercial landlords can appeal their assessment if they believe it overstates fair market value.
GST on Commercial Rent
The 5% federal Goods and Services Tax that applies to most commercial rent in Canada, including BC. Tenants pay GST on top of rent; the landlord remits it to the Canada Revenue Agency (CRA). Commercial landlords typically register for GST and can recover GST paid on operating expenses through Input Tax Credits. Different rules apply to residential rent (generally GST-exempt).
Strata Depreciation Report (BC)
A formal capital planning document that strata corporations in BC are required to obtain. Under recent BC Strata Property Act amendments effective July 2024, corporations with five or more strata lots must update the report every five years, and the previous option to defer by 3/4 vote has been eliminated. Provides a 30-year forecast of major repairs and capital replacement costs. Critical for commercial strata owners evaluating the strata's financial health and exposure to future special levies.
5. Operations & Management
Lease Abstract
A condensed summary of a commercial lease's key business terms — parties, premises, term, rent, escalations, options, notice deadlines, and any unusual provisions. Used by property managers for active lease administration and by buyers for due diligence. A well-prepared lease abstract surfaces obligations and deadlines that might otherwise be missed in the full lease document.
Lease Administration
The operational discipline of tracking and acting on all obligations in a commercial lease — rent collection, escalations, renewal option windows, notice deadlines, CAM recoveries, and reconciliations. The difference between good and poor lease administration can be tens of thousands of dollars per year on a mid-sized BC commercial property.
Trust Account
A separate bank account where licensed BC commercial property managers hold client funds — rent collected, security deposits, operating reserves — distinct from the firm's operating accounts. Required and regulated under RESA and BCFSA rules. Trust account discipline is one of the most heavily audited areas in BC real estate brokerage.
Replacement Cost / Total Insurable Value (TIV)
The estimated cost to rebuild a commercial structure from scratch at current construction prices — not its market value, purchase price, or assessed value. The basis for commercial property insurance coverage in BC. Underinsuring against the true replacement cost can trigger a co-insurance penalty, dramatically reducing insurance payouts. See our replacement cost appraisal guide.
Co-insurance Clause
A standard clause in BC commercial property insurance policies requiring the owner to insure the property for at least a defined percentage (typically 80%, 90%, or 100%) of its true replacement cost. If insured for less, the owner becomes a co-insurer and recovers losses proportionally — often a significantly reduced payout even on a partial loss. One of the most consequential and least understood provisions in commercial property insurance.
Property Condition Assessment (PCA)
A formal building inspection and report documenting the physical condition of a commercial property — structure, building envelope, mechanical systems, electrical, plumbing, roof, parking surfaces — typically with a 5–10 year capital expenditure forecast. Standard in Greater Vancouver commercial acquisitions as part of due diligence; also valuable as a baseline at the start of a new property management engagement.
Building Envelope
The physical separation between a building's interior and exterior — walls, roof, windows, doors, foundation, and waterproofing systems. The condition of the building envelope is one of the most consequential aspects of a commercial property's long-term value, particularly in Greater Vancouver's wet climate where envelope failures can lead to expensive repairs and tenant disputes.
Capital Reserves / Reserve Fund
Money set aside by a commercial property owner (or strata corporation) for future major repairs and capital replacement — roof, HVAC, parking lot resurfacing, building envelope work. Distinct from operating expenses, which cover day-to-day costs. In BC, strata corporations are required by law to maintain a Contingency Reserve Fund; individual commercial property owners do so as a matter of prudent financial management.
Rent Roll
A consolidated document listing every tenant in a commercial property along with their unit, leased square footage, lease term, base rent, additional rent, security deposit, arrears, and key lease dates. The single most-requested document in commercial PM — used for owner reporting, lender financing, due diligence in sales, and day-to-day operations. A current and accurate rent roll is one of the clearest indicators of how well a property is being managed.
Property Management Agreement (PMA)
The foundational contract between a commercial property owner and a property management firm. Defines the scope of services, fee structure, term, termination provisions, trust account handling, and the manager's authority to make decisions on the owner's behalf. In BC, governed by RESA and BCFSA rules — terms vary widely between firms, and the termination clause in particular deserves careful review before signing. See our switching managers guide for what to look for.
