Commercial vs. Residential Tenancy: The Critical Difference
The BC Residential Tenancy Act provides extensive statutory protections for residential tenants: fixed rent increases, no-fault eviction restrictions, standardized notice periods, mandatory dispute resolution through the RTB. None of this applies to commercial tenants. Commercial leases are governed by the BC Commercial Tenancy Act (minimal provisions) and contract law — what the parties agreed to in the lease is what governs.
| Feature | Residential Tenancy | Commercial Tenancy |
|---|---|---|
| Governing law | BC Residential Tenancy Act | Contract law + BC Commercial Tenancy Act |
| Rent increase limits | Annual cap tied to CPI (2–3.5% in recent years) | No limit — as negotiated in the lease |
| Eviction protections | Extensive — specific grounds required | As per lease terms; landlord has more flexibility |
| Dispute resolution | BC Residential Tenancy Branch | BC Supreme Court (civil litigation) |
| Standard lease form | RTB standard form required | Fully negotiated; no standard form |
| Security deposit | Capped at 0.5 month's rent | Negotiated — 2–6 months common |
Mixed-Use Buildings: Know Which Act Applies
In a mixed-use building with a retail ground floor and residential units above, the commercial units are governed by the Commercial Tenancy Act and the residential units by the Residential Tenancy Act. When purchasing mixed-use buildings, confirm which tenancies are commercial and which are residential — they have completely different due diligence requirements.
Commercial Lease Structures: Gross, Net, and Everything in Between
The most important question in any commercial lease is: who pays for what? The answer determines the true net income to the landlord and the total occupancy cost to the tenant.
Gross Lease (Full Service)
Tenant pays one all-in rent. Landlord pays all operating costs: property tax, insurance, utilities, maintenance, management. Most common in older office buildings and some industrial.
Landlord pays: property tax, insurance, maintenance, utilities
Landlord's net income: $4,000 minus all operating costs
Net Lease (Single Net / N)
Tenant pays base rent + their proportionate share of property taxes. Landlord still pays insurance and maintenance. Less common.
Landlord pays: insurance, maintenance
Landlord's net income: $3,000/month (more predictable)
Double Net Lease (Net Net / NN)
Tenant pays base rent + property taxes + building insurance. Landlord pays maintenance and structural repairs. Common in some retail and office.
Landlord pays: maintenance, structural
Landlord's net income: $2,800/month
Triple Net Lease (NNN) — Most Common for Standalone Retail
Tenant pays all costs: base rent + property taxes + insurance + all maintenance and repairs. The landlord's income is nearly passive. Used for national retailers (Tim Hortons, McDonald's, pharmacies) and most standalone commercial buildings.
Landlord pays: nothing (or structural only)
Landlord's net income: $2,500/month (highly predictable)
NNN leases with creditworthy national tenants command premium cap rates and are highly valued as investment properties
Modified Gross / Net Plus CAM (Most Common in Multi-Tenant Buildings)
Tenant pays base rent + their proportionate share of CAM charges (property tax, insurance, operating costs, management fee). Base rent covers the landlord's ownership cost; CAM is the operating cost pass-through. Most strip malls and office buildings use this structure.
Total occupancy cost: $3,800/month
Annual CAM reconciliation adjusts for actual vs. estimated costs
CAM Charges: What They Include and How to Analyze Them
CAM (Common Area Maintenance) charges in a multi-tenant building typically include:
Typically Included in CAM
- • Property taxes (landlord's share)
- • Building insurance
- • Common area utilities (parking lot lights, hallway HVAC)
- • Parking lot maintenance and snow removal
- • Landscaping
- • Common area cleaning
- • Building management fees (often 10–15% of other CAM costs)
- • Security systems
- • Elevator maintenance (if applicable)
Sometimes Included / Negotiable
- • Capital improvements (roof replacement, parking lot repaving)
- • Structural repairs
- • Leasing commissions
- • Legal and accounting fees
- • Merchant association fees
- • Marketing and promotion
- • Administrative overhead
Analyzing CAM in an Investment Property Purchase
When underwriting an investment property with CAM-paying tenants, buyers should request actual CAM reconciliation statements for the past 2–3 years. Key questions:
- →Are CAM charges capped? Some leases have CAM caps (e.g., annual increases limited to 5%). A cap limits upside recovery of rising costs but provides predictability for tenants and can be a selling point.
- →What does the management fee percentage apply to? If the management fee is 15% of all other CAM costs, that's compounding — higher as other costs rise. Watch for management fees on capital items.
- →Are there outstanding reconciliation disputes? Tenants who dispute CAM charges represent contingent liability — request confirmation that all reconciliations have been accepted and paid.
- →Who is excluded from the CAM pool? Anchor tenants (large grocery stores, major retailers) often negotiate their own managed spaces and pay a fixed contribution rather than a proportionate share — which increases the CAM burden on smaller tenants.
Key Commercial Lease Clauses Every Realtor Should Know
Permitted Use
High ImpactDefines exactly what business the tenant can operate. A lease permitting 'retail sales of clothing' cannot be used for a restaurant or cannabis dispensary. When an investment property is purchased, the permitted use determines whether the buyer can change tenant mix — and whether the current tenant can expand their business type.
Exclusivity Clause
High ImpactGrants the tenant the exclusive right to operate a specific type of business in the building or plaza. An exclusivity clause for 'hair services' prevents the landlord from leasing to any other hair salon. These clauses survive ownership changes and can significantly restrict future leasing to new tenants.
Assignment and Subletting Rights
High ImpactDetermines whether and how the tenant can assign the lease to a new business. Most commercial leases require landlord consent to assign (not to be unreasonably withheld). Strong assignment rights make a tenant's business easier to sell — which benefits both tenant and landlord if the replacement tenant is creditworthy.
Renewal Options
Medium-High ImpactOptions to renew the lease at the end of the term — at a specified rent or at market rent. Multiple renewal options (e.g., two five-year options) can extend a lease to 15–20 years, locking in a long-term tenant. Important for investment value: a tenant with remaining options is worth more than one with an expiring lease.
Rent Escalation / CPI Adjustments
Medium ImpactHow rent increases over the lease term. Fixed annual increases (e.g., 2.5%/year) are predictable. CPI-based increases track inflation. 'Fair market rent' resets at renewal can jump significantly in strong markets. For investment analysis, model the rent escalation schedule across the full lease term including renewals.
Tenant Improvement (TI) Allowance
Medium ImpactAn upfront cash contribution from the landlord to help the tenant build out their space. A $100,000 TI allowance from the original landlord is already paid and gone — but the buyer inherits the obligation to honor any remaining TI allowance on future lease renewals or new leases. Check whether any TI obligations are outstanding.
Demolition / Redevelopment Clause
Variable ImpactAllows the landlord to terminate the lease if they plan to demolish or redevelop the building, typically with 6–12 months notice. Present in urban mixed-use properties in redevelopment zones. Valuable for landlords who want flexibility, problematic for tenants who have invested heavily in the space.
Personal Covenant / Guarantee
High for landlord ImpactPersonal guarantee by the principals of a corporate tenant. If the tenant corporation defaults, the guarantors are personally liable. A lease backed by a personal guarantee from a creditworthy individual is worth significantly more than one guaranteed only by a corporate entity. Review guarantee terms — some are limited in time or amount.

When representing a buyer purchasing a property with commercial tenants, request and review the following before subject removal:
Calculating NOI and Cap Rate for Commercial Properties
Commercial properties are valued on their income — specifically Net Operating Income (NOI) capitalized at a market cap rate. Understanding this is essential for any realtor working with investment properties, including smaller mixed-use and retail buildings that show up in residential investment portfolios.
NOI Calculation Example
Gross scheduled rent (all tenants): $180,000/yr
Less: vacancy allowance (5%): ($9,000)
Effective gross income: $171,000/yr
Operating expenses (landlord-paid):
Property management (8%): ($13,680)
Insurance: ($4,500)
Maintenance & repairs: ($6,000)
Property taxes (if not NNN): ($0 - NNN lease)
Total operating expenses: ($24,180)
Net Operating Income (NOI): $146,820/yr
Market cap rate for this property type: 5.5%
Implied value (NOI ÷ Cap Rate): $2,669,455
| Property Type | Typical Cap Rate (BC, 2025) | Notes |
|---|---|---|
| NNN with national tenant (A-credit) | 4.0–5.0% | Tim Hortons, Dollarama, pharmacy — low risk, low yield |
| Multi-tenant strip retail (good market) | 4.5–6.0% | Metro Van suburban; quality tenant mix |
| Office (suburban) | 5.5–7.5% | Higher cap rates post-COVID; rising vacancy |
| Industrial / light industrial | 3.5–5.0% | BC industrial in high demand; compressed caps |
| Mixed-use (retail + residential) | 4.5–6.0% | Blended based on unit mix; zoning value can exceed income value |

Frequently Asked Questions
What is the difference between a gross lease and a net lease in BC commercial real estate?
In a gross lease, the tenant pays all-in rent and the landlord covers all operating costs. In a net lease, the tenant pays base rent plus some or all operating costs. Triple net (NNN) leases require tenants to pay base rent plus property taxes, insurance, and all maintenance — making the landlord's income nearly passive. Modified gross/net plus CAM is most common in multi-tenant buildings.
What are CAM charges in a commercial lease?
CAM (Common Area Maintenance) charges are a tenant's proportionate share of operating costs for the building and common areas — property taxes, insurance, maintenance, landscaping, parking lot, management fees. CAM is estimated monthly and reconciled annually based on actual costs. CAM charges vary significantly by lease and building type — always review historical reconciliations when underwriting an investment property.
Does BC's Residential Tenancy Act apply to commercial leases?
No. The BC Residential Tenancy Act does not apply to commercial tenancies. Commercial leases are governed by contract law and the BC Commercial Tenancy Act (which provides minimal statutory framework). Commercial tenants have far fewer automatic protections — rent increases, eviction grounds, and dispute processes are determined entirely by the negotiated lease terms.
What is a personal covenant in a commercial lease and why does it matter?
A personal covenant is a guarantee by the business principals that they are personally responsible if the corporate tenant defaults. It means if the business fails, the landlord can pursue the individuals. A lease backed by a personal guarantee from a creditworthy guarantor is worth more than one guaranteed only by a corporation — critical for investment property underwriting.
What should a buyer review in a commercial tenant lease before purchasing an investment property?
Key items: remaining lease term and renewal options, base rent and escalation schedule, lease structure (gross/net/NNN) and what costs the tenant pays, permitted use restrictions, exclusivity clauses, assignment/subletting rights, personal guarantees, outstanding TI allowances, CAM reconciliation history, and any disputes or claims between landlord and tenant.
