The hidden costs in a commercial lease
The rent in the ad is a starting point. Here is what gets added on top, with numbers, so the monthly bill doesn’t surprise you. Expect additional rent for property tax, insurance and common area costs, plus GST, the load factor and sometimes a management fee. Ask for last year’s actual numbers, not just the estimate.

1. You pay for more space than you use
Rent is charged on rentable area, which includes your share of lobbies, corridors and washrooms. The load factor is the gap between rentable and usable. A 2,000 sf usable space with a 15% load factor is billed as 2,300 sf. Full explanation in load factor explained.
2. Net rent plus additional rent
Most Vancouver commercial space is quoted net. On top of base rent you pay additional rent: your share of property taxes, building insurance and operating costs (often called CAM, for common area maintenance).
It’s billed monthly on an estimate and reconciled after year end, so there can be a catch-up bill. See what triple net really costs.
3. GST
5% GST applies to commercial rent, base and additional. Easy to forget in a budget.
A worked example
| Item | Amount |
|---|---|
| Usable area | 2,000 sf |
| Load factor 15%, so rentable area | 2,300 sf |
| Base rent $30 /sf/yr | $69,000 /yr |
| Additional rent $16 /sf/yr | $36,800 /yr |
| Total before GST | $105,800 /yr |
| Monthly, before GST | $8,816.67 |
| Monthly, with 5% GST | $9,257.50 |
The ad said $30 a square foot. The real monthly bill is about $9,260. Run your own numbers in the lease calculator.
4. Escalations
Rent steps, often each year or every few years. Over a five-year lease they add up, so compare offers on the total over the term.
5. Moving in and moving out
- Build-out above the landlord’s allowance, plus permits and design.
- Overlapping rent while you build the new space and finish the old lease.
- Restoration at the end: removing your fixtures or returning the space to its original state.
- Holdover rent if you stay past your lease end without a new deal, often at a premium.
- Utilities, separately metered or billed as part of operating costs.
