Four guides for a clearer lease decision

Avoid common mistakes →The process
From requirements to keys
A thoughtful search begins before the first tour. The sequence varies by market and property, but these stages provide a practical framework.
Build the team
Consider a tenant representative, commercial leasing lawyer, accountant, contractor, and technical specialists as needed.
Search and tour
Compare practical fit, not just appearance. Note building systems, accessibility, condition, neighbours, and operating limits.
Shape the deal
A letter of intent often records proposed business terms before the full lease. Some provisions may still be binding.
Investigate and negotiate
Confirm zoning and use, costs, building condition, insurance requirements, improvement scope, and the complete lease language.
Sign and prepare
Complete approvals, insurance, deposits, permits, build-out, utilities, and move-in coordination before opening.
Cost structure
Commercial lease types, in plain language
The label is only a starting point. The lease itself controls which party pays each expense, how costs are calculated, and what can change over time.
GROSS
Gross lease
The tenant pays an agreed rent and the landlord generally pays most building operating expenses. Costs may still be reflected in the rent, and exclusions or expense adjustments can apply.
SHARED
Modified gross
Tenant and landlord divide operating expenses in a negotiated way. For example, one party may cover taxes while the other pays utilities or increases over a base year.
ADDED COSTS
Net lease
In addition to base rent, the tenant pays some property expenses. “Single net” often adds property taxes; “double net” commonly adds taxes and insurance. Definitions vary.
NNN
Triple-net lease
The tenant typically pays base rent plus a share of property taxes, building insurance, and maintenance or operating expenses. Roof, structure, and capital costs require careful review.
Important: Industry labels are not perfectly standardized. Confirm the exact expense clauses, exclusions, calculation methods, audit rights, and caps in the proposed lease.
Negotiation
Terms worth examining closely
Base rent matters, but a workable lease balances total occupancy cost, operational needs, risk, and room for the business to change.
Tenant improvement allowance
A landlord contribution toward approved improvements. Define the amount, eligible work, payment timing, approval process, ownership of improvements, and what happens if costs exceed the allowance.
Escalation clauses
Rent may increase by fixed steps, a percentage, an index, or market review. Model the full term and understand floors, caps, review dates, and how additional rent may also change.
Renewal options
An option can preserve continuity, but deadlines and conditions are often strict. Review notice windows, rent-setting method, required tenant standing, and whether the option can be assigned.
Personal guarantees
A guarantee may expose an owner’s personal assets if the tenant defaults. Negotiate scope, duration, caps, burn-off provisions, and release conditions with legal advice.
Exit and transfer rights
Assignment, subletting, relocation, redevelopment, demolition, early termination, and change-of-control clauses affect flexibility. Understand consent standards and continuing liability.
First lease
Common pitfalls to avoid
Commercial tenants usually receive fewer statutory protections than residential tenants. The written agreement carries exceptional weight.
Comparing base rent only
Estimate total occupancy cost: additional rent, utilities, insurance, maintenance, repairs, taxes, permits, and improvements.
Assuming the use is allowed
Confirm zoning, building rules, permits, licences, exclusivity restrictions, and the lease’s permitted-use wording before committing.
Underestimating build-out
Clarify plans, approvals, contractors, code upgrades, funding, delays, access, and when rent begins relative to possession and opening.
Leaving maintenance vague
Identify responsibility for HVAC, plumbing, electrical, roof, structure, storefront, accessibility, and major capital replacements.
Ignoring the long-term fit
Think through growth, contraction, accessibility, staffing, delivery, customer traffic, renewal, relocation, and exit scenarios.
Signing before due diligence
Do not treat the landlord’s form as a formality. Allow time for legal, financial, technical, and operational review.

FAQ
Do I need a commercial broker?
Not every transaction requires one, but a broker who understands your market and tenant requirements can help identify options, compare business terms, coordinate the search, and negotiate. Ask how the broker is compensated and whom they represent.
Is a letter of intent legally binding?
Many letters of intent are intended to be mostly non-binding, but confidentiality, exclusivity, access, cost, or other clauses may bind the parties. Wording and local law matter, so obtain legal advice before signing.
What is “additional rent”?
It is a broad term often used for tenant-paid amounts beyond base rent, such as a share of taxes, insurance, common-area costs, utilities, management fees, or other expenses. The lease should define each component and how it is calculated.
When should a lawyer review the lease?
Ideally, involve a commercial leasing lawyer early enough to advise on the letter of intent and before commitments become difficult to change. Legal review of the full lease should occur before signing.
