Occupancy Fees Explained: Paying Rent on a Condo You Bought (2026)
Before a new condo is registered, buyers pay the builder occupancy fees instead of a mortgage: interest plus estimated tax and condo fees. How they’re set.
A new condo can be occupied before the building is legally registered as a condominium. During that "interim occupancy" period you do not own the unit and cannot get a mortgage on it, so you pay the builder a monthly occupancy fee instead: interest on the unpaid balance at the builder's prescribed rate, plus estimated property tax, plus estimated condo fees. On a $500,000 unit with $50,000 of deposits paid, that is roughly $2,750 a month. None of it reduces the price; it is rent, and it can last from a few weeks to over a year.
Figures come from the CostToClose guided buying flow.
The three components
| Component | Basis (Ontario, Condominium Act s. 80) | On a $500,000 unit, $50,000 paid |
|---|---|---|
| Interest on the unpaid balance | Prescribed rate: the one-year bank posted mortgage rate at the time of occupancy, applied to $450,000 | ≈ $2,060/mo at 5.5% |
| Estimated property tax | Builder's estimate for the unit | ≈ $300/mo |
| Estimated common expenses | Builder's estimate of the condo fee | ≈ $400/mo |
| Occupancy fee | ≈ $2,760/mo |
Figures computed using the CostToClose calculator, 14 September 2026. The interest component is the biggest and is fixed by statute in Ontario; the estimates are the builder's and are not adjusted later.
Paying more of the price early (some builders allow extra deposits at occupancy) reduces the interest component proportionally.
Why it exists
The builder has delivered a finished unit but cannot transfer title until the municipality and land registry register the condominium plan, which depends on the whole building being complete and inspected. Registration typically follows occupancy by three to nine months, sometimes longer. The occupancy fee compensates the builder for the money still tied up in your unit.
What it is not
- Not a mortgage payment. No principal reduction, no equity.
- Not tax deductible for an owner-occupant.
- Not refundable, and not credited against the purchase price at final closing.
- Not covered by the mortgage. Your lender's commitment is for final closing; some lenders will let the rate hold span the occupancy period, others will not.
Worked example
$500,000 unit, occupancy in March, registration in November: eight months.
| Item | Amount |
|---|---|
| Occupancy fees (8 × $2,760) | $22,080 |
| Equity built | $0 |
| Compare: mortgage payment on $450,000 at 4.49% for 8 months | $19,905, of which ≈ $6,645 would have been principal |
The buyer spent $22,080 to live in the unit and would have spent $19,905 with about $6,645 of it retained had they owned it. The gap is the real cost of interim occupancy. Reproduce the mortgage figure.
What to ask before you buy pre-construction
- The builder's estimated occupancy date and estimated registration date, and the gap between them on the builder's last three projects.
- Whether you may pay additional deposit at occupancy to reduce the interest component.
- Whether your lender's rate hold will survive a delayed registration.
- What the estimated tax and common-expense figures are based on.
Frequently asked questions
What is an occupancy fee?
A monthly payment to the builder between the day you move into a new condo and the day the building is registered and you take title. It covers interest on the unpaid balance plus estimated tax and condo fees.
How long does interim occupancy last?
Typically three to nine months; longer for large towers or where registration is delayed. Ask the builder for the record on past projects.
Does the occupancy fee go toward the purchase price?
No. It is not credited against the price and builds no equity.
Can I get a mortgage during interim occupancy?
No. You do not own the unit until registration. The mortgage funds at final closing.
Is the occupancy fee regulated?
In Ontario, the Condominium Act sets the interest rate and the three components. Other provinces have similar but not identical rules; check the agreement.
