Buying
You think you’re paying too much rent
Sometimes the rent is fine and the extras are the problem. I break down what you pay, compare it with similar spaces and tell you what can be fixed now and what waits for renewal. Start with your additional rent statements.

The problem
The rent on paper is rarely the whole cost. Additional rent, management fees, escalations and load factor can add a lot. A common surprise is paying for “rentable” area that includes a share of hallways and lobbies, space you can’t actually use.
Overcharges in operating costs can sit unnoticed for years.
What I do about it
I break your cost down: base rent, additional rent, load factor, escalations. Then I check it against similar spaces and your lease’s own rules for what can be charged. If something is off, you can see what, by how much, and what to ask for.
What your landlord wants
Landlords want to recover their real costs and keep the building’s rent level up. Most aren’t trying to overcharge, but they won’t volunteer a refund either. They respond to a clear, polite request backed by the lease and the numbers.
Where everybody wins
Fix what’s wrong, and agree on what’s fair for the rest of the term. You stop overpaying, and the landlord keeps a happy tenant without a dispute.
Where the extra money usually goes
- Base rent above what comparable spaces nearby lease for.
- Load factor. You pay for rentable area, which includes a share of common areas. Two spaces with the same usable area can have very different bills. See load factor explained.
- Additional rent. Property taxes, insurance and operating costs (often called CAM). These are passed through to you on a net lease and can climb quietly year after year.
- Escalations that compound faster than the market.
- Admin fees on top of operating costs, and costs that arguably belong to the landlord, like major repairs or upgrades.
What we can do about it
- Compare your rent and additional rent against similar spaces, on a like-for-like basis.
- Review your annual additional rent statements and reconciliations. Many leases give tenants a right to ask for supporting details, and sometimes to audit.
- Separate what’s fixable now (billing errors, questionable charges) from what waits for renewal (base rent), and plan for both.
- If your renewal is within 18 months, start that conversation with real numbers.
I can’t give legal advice, and some of this is a lawyer’s job. What I bring is the market evidence and the negotiation, which is where most of the savings come from.
Questions people ask
How do I know if my commercial rent is fair?
Compare like with like: the same area, use and size, on the same basis (net or gross, rentable or usable area). Then look at additional rent per square foot against similar buildings. A tenant’s agent can pull comparable leases and listings for you.
Can I dispute my CAM or operating cost charges?
Often, yes. Many leases require the landlord to reconcile actual costs each year and give tenants some right to review them. What’s allowed depends on the wording of your lease, so start there and involve your lawyer for anything formal.
What should I gather, ask and watch for?
Documents to gather
- Your lease, especially the additional rent clause
- The last two or three year-end reconciliations
- The measurement certificate for your space, if you have one
- Recent listings for similar space nearby
Questions to ask
- What exactly is in additional rent, and is there a management fee on top?
- Can I see the backup for the year-end reconciliation?
- When was my space last measured, and to what standard?
- Is the base rent above what similar spaces are asking today?
Common mistakes
- Paying reconciliations without checking them
- Comparing base rent only, not the total cost
- Waiting until renewal to raise it
- Stopping rent payments, which can put you in default
Typical timeline
- Week 1Gather the lease and statements
- Weeks 2 to 4Compare costs and the market; list questions
- Month 2Raise it with the landlord in writing
- Next renewalNegotiate the fix into the new terms
Typical ranges. Your lease, lender and the City set the real dates.

How to check if your rent is fair
- Work out your all-in cost per month: base rent, additional rent, parking, GST and any other charges.
- Compare it with similar spaces nearby on the same basis, using what tenants actually signed for. Asking rents can be well off.
- Look at your additional rent history. Ask for the year-end reconciliations.
- Check your measured area. Ask how it was measured and what load factor was used.
The lease cost calculator does step one for you.
What you can do mid-lease
Not much changes the rent mid-term unless the lease allows it. But you can audit your additional rent if the lease gives you that right, fix measurement errors, and start renewal talks early, sometimes with a blend-and-extend: a lower rent now in exchange for a longer term.
Example: a blend-and-extend
A tenant with two years left at $38 per square foot, where similar space now leases for $32, agrees to a new five-year term. The landlord blends the rate to $34 starting now. The tenant saves money today, and the landlord gets certainty.
Real numbers vary, so this is only to show how it works.
Run the numbers
- Total occupancy costThe advertised rent is only part of what a commercial space costs.
- Rent-to-sales checkA quick check landlords and lenders use: total occupancy cost divided by sales.
- TI allowance and free rentTwo offers with the same face rent can cost very different amounts once you count free months and the tenant improvement allowance.
