What Additional Rent Actually Covers

Every commercial listing quotes a rate. Very few of them quote what you will actually pay each month. The gap between those two numbers is additional rent, and it is the thing a first time tenant is most often caught out by.

Two numbers, not one

Commercial space in Alberta is usually quoted as a net rate: a figure per square foot per year that goes to the landlord as rent and covers nothing else. Additional rent is what it costs to run the building, divided among the tenants in it, and charged the same way, per square foot per year.

Add the two together and you have your occupancy cost. Multiply by your area, divide by twelve, and you have the monthly number your business has to cover before it has paid for one hour of labour or one item of stock. That is the figure worth knowing before you tour anything, because it decides which spaces are worth looking at.

What sits inside the second number

Additional rent is not a single charge. It is a bundle, and in most buildings it holds four things.

Property taxes are usually the largest component and the one nobody in the building controls. A reassessment can move this line without anybody doing anything differently.

Building insurance covers the structure. It does not cover your fixtures, your stock or your liability, all of which you carry separately.

Common area maintenance is the running of everything nobody leases: snow clearing, parking lot upkeep, landscaping, exterior lighting, shared utilities, cleaning and minor repairs.

The management fee pays whoever administers the building. Worth asking whether it is charged on the other operating costs or alongside them, because the two are not the same and the difference is real.

Your share is a fraction, and the fraction matters

Your share is normally your area divided by the leasable area of the building. What counts as leasable is a definition in your lease, not a fact about the building.

The question to ask is what happens when the building is not full. Under some leases the empty units carry their own share and the landlord absorbs it. Under others the costs are grossed up and spread across the tenants who are actually there, which means your bill rises because your neighbour left. Both are common. Only one of them is in your interest, and you will not know which you have unless you read for it.

Estimates first, reconciliation later

What you are charged monthly is an estimate, set before the year begins. After year end the landlord totals what the building actually spent and reconciles the estimate against it. You get a bill for the difference or a credit against it.

This is where the surprises come from. A year with a roof repair, a hard winter, or a tax reassessment reconciles higher than the estimate quoted to you when you signed. Nothing improper has happened. The estimate was an estimate.

What to ask before you sign

Ask for the last two or three years of actual operating costs rather than the current estimate. The estimate is what gets advertised; the actuals are what get charged.

Ask what is excluded. A short exclusion list is not a good sign.

Ask how capital work is treated. If the roof is replaced, is that recoverable from tenants, and over how many years? A capital cost recovered in one year lands very differently from the same cost spread across its useful life.

Ask about the gross up, in those words.

Ask whether the management fee is calculated on the other operating costs.

Why we publish the total

On our listings the net rate, the additional rent and the total sit next to each other, with the monthly figure underneath where the area is known. Where a number has not been set it reads On request rather than being left blank, because a figure that is missing should look missing rather than look like zero.

None of this is complicated. It is simply not usually shown, and a tenant who reads a net rate as the full cost is the one who signs for space that cannot carry itself.
