Interim occupancy fees are monthly payments you make to the builder of a pre-construction condo during the stretch between getting your keys and actually taking ownership at final closing. None of that money comes off your purchase price, and none of it builds equity. Under Section 80(4) of Ontario's Condominium Act, 1998, the builder may charge a monthly amount that cannot exceed the sum of three components: interest on the unpaid balance of your purchase price, an estimate of the municipal property taxes for your unit, and the projected monthly common expense contribution. Buyers call it phantom rent. The nickname is fair.
Why you can move in before you own anything
This period exists because of how condominium registration works in Ontario. A condo unit cannot legally transfer to a buyer until the entire building is registered with the Land Registry Office, and registration requires the builder to complete all of the common elements. That means lobbies, hallways, elevators, amenity spaces, the whole package. Your unit might be finished a year before the party room is.
So the Condominium Act permits builders to grant occupancy in advance while they finish the rest of the building. At interim closing you typically pay the remaining deposit set out in your agreement, your lawyer handles a short stack of documents, and you get keys. You are now living in a unit you do not yet own, inside a building still run by the builder, because the condominium corporation does not exist until registration happens.
What the monthly fee is made of
The interest component is usually the largest of the three. It is calculated using the Bank of Canada's reported chartered bank administered interest rate for a conventional one-year mortgage, and that rate is locked on the first day of the month in which your interim occupancy begins. It applies to the unpaid balance of the purchase price, meaning the total price minus every deposit you have already paid.
The second piece is an estimate of municipal property taxes for the unit. The city has not assessed your individual suite at this stage, so the builder projects the taxes and divides them into a monthly amount.
The third piece is the projected common expense contribution, which works as a preview of your future condo fees. It covers the operating costs that will eventually belong to the condominium corporation. One thing worth knowing here: builders are prohibited under the Condominium Act from profiting on occupancy fees. They exist to cover the carrying costs of the development, nothing more.
How long the meter runs
The occupancy period typically lasts three to six months. In large developments it can stretch to a year or longer. There is also a structural unfairness in the timing that surprises people. Lower-floor units tend to be ready earlier, which means those buyers often spend the most time in interim occupancy before the building registers and final closing occurs. The buyer on the thirty-eighth floor might pay phantom rent for two months while the buyer on the third floor pays it for ten.
You cannot control when registration happens. The builder controls the construction schedule, and the municipality and the Land Registry Office control the rest. What you can control is understanding the Statement of Critical Dates in your agreement, which sets out the framework for occupancy and the outside dates before you ever commit.
How to lower the fee
The interest portion is the lever. Because it is charged on the unpaid balance of the purchase price, buyers who can make an additional lump-sum payment at interim closing reduce that balance and shrink the monthly interest charge for the entire occupancy period. Not every agreement permits this, and the time to find out is before you sign, not after.
That is one of several reasons the 10-day cooling-off period matters so much. Have a real estate lawyer review your Agreement of Purchase and Sale before those ten days expire. The occupancy fee provisions and the Statement of Critical Dates both live in that document, and a good lawyer will flag whether you have the right to prepay, what happens if registration drags, and what your monthly carrying cost will actually look like. At Advantage Group Real Estate we treat that ten-day window as a working period rather than a formality, because it is the only point in the process where you can still walk away clean.
What changes at final closing
Final closing is the day the building registers and the unit becomes legally yours. Your mortgage is funded, title transfers into your name, and the interim occupancy fees stop. Monthly condo fees begin flowing to the newly formed condominium corporation instead of the builder. You also gain the full rights of ownership, which means you can vote at owners' meetings, sell the unit, or refinance.
Budget for this day separately. Land transfer tax comes due at final closing, along with closing adjustments and legal fees, and buyers who mentally filed the deal as finished back at interim closing sometimes get caught flat. The phantom rent ends. The real ownership costs begin.
Pre-construction agreements are builder documents, written by builder lawyers, and the occupancy provisions are where a lot of the real cost hides. Jeremy Van Caulart and the team at Advantage Group Real Estate, brokered by Royal LePage Signature Realty, review these agreements with pre-construction buyers across Toronto and will say plainly when the carrying math does not work. Run the occupancy numbers before you fall in love with the floor plan.
Frequently asked questions
Do interim occupancy fees count toward my purchase price?
No. They are a carrying charge paid to the builder, and none of it is credited against what you owe at final closing. The fee covers interest on your unpaid balance, estimated property taxes, and projected common expenses. It builds no equity.
Can I rent out my unit during interim occupancy?
Only if the builder allows it. Most pre-construction agreements prohibit leasing during occupancy unless you have negotiated permission, sometimes through an amendment that carries its own fee. Check your agreement before you assume rental income will offset the occupancy fee.
How do I find out when my occupancy will start?
Your Agreement of Purchase and Sale includes a Statement of Critical Dates that sets out the framework for your occupancy date and the outside dates the builder must meet. Those dates can shift within that framework as construction progresses. A lawyer review during the 10-day cooling-off period is the right moment to understand how much movement is possible.
