Interim occupancy is the period between the day you move into your new condo and the day the building legally registers and your mortgage funds. During it you pay the builder a monthly occupancy fee made up of three parts: an interest component on your unpaid balance, an estimated property tax component, and a projected common expense component. None of it reduces your mortgage principal — which is why it is often called phantom rent. The period commonly runs several months and can extend beyond a year, and it is the cost pre-construction buyers most often fail to budget for. Lower floors occupy first and pay longest.
Of everything in a pre-construction purchase, this is the concept people understand least and the one that causes the most financial distress. I have had buyers arrive at occupancy genuinely unaware that they were about to start paying a substantial monthly amount that would not touch their mortgage.
It is not hidden. It is in the agreement of purchase and sale. But it is buried in dense language, it is rarely explained clearly at a sales centre, and it is easy to nod past when you are focused on floor plans and finishes.
So here it is in plain terms — what it is, how it is calculated, how long it lasts, and how to budget for it before you sign rather than after you move in.
1What interim occupancy actually is
A condominium building cannot transfer individual units to owners until the corporation is legally registered. Registration requires the building to be substantially complete and the survey and legal work to be finished and approved.
But buildings are occupied floor by floor as they finish. So there is a gap: the lower floors are habitable and people want to move in, while the building as a whole is not ready to register.
Your position during this gap
You live in the unit. You do not own it. The builder still holds title. Your mortgage has not funded, because there is no title for the lender to secure against. You have paid your deposits but not the balance of the purchase price.
In exchange for living in a unit you have not yet paid for, you pay the builder a monthly occupancy fee.
What this means practically
You cannot sell the unit in the ordinary way during occupancy — only assign, subject to builder consent. Whether you can rent it out during occupancy depends entirely on your agreement; many builders prohibit it, and some charge a fee for the right. If renting during occupancy matters to you, negotiate that right into the contract before you sign.
You also cannot claim ownership-related tax positions that depend on holding title.
The bottom line: You are living in the unit but you do not own it and your mortgage has not started. That is the whole reason occupancy fees exist.
2How the occupancy fee is calculated
The fee is not arbitrary. It is made up of three defined components.
1. Interest on the unpaid balance
This is normally the largest part. You have paid deposits — say 20% — and owe the remaining 80%. The builder charges interest on that outstanding balance, at a rate that is prescribed rather than set at the builder’s discretion.
The practical consequence: the larger your deposit, the smaller your occupancy fee. That is a genuine and often overlooked argument for a larger deposit if you can afford it and expect a long occupancy period.
2. Estimated property tax
An estimate of the municipal property tax attributable to your unit. Because it is an estimate made before the unit is assessed, it can differ from what the actual tax turns out to be. Differences are reconciled at final closing through the statement of adjustments — sometimes in your favour, sometimes not.
3. Projected common expenses
The builder’s projection of your monthly maintenance fee, from the budget in the disclosure statement. This is a projection, not a guarantee. Developers have historically projected optimistically, and it is common for actual fees after the first year — once the corporation has real operating history and a completed reserve fund study — to come in higher than the projection.
When you budget, assume the real fee will be somewhat above the projected one.
The bottom line: Interest on your unpaid balance is usually the biggest component, which means a larger deposit directly reduces your monthly occupancy fee.
3Why none of it builds equity
This is the part that stings, and the part people most often misunderstand until it is happening to them.
The money is gone
Occupancy fees do not reduce your purchase price. They do not pay down principal. They are not credited against your balance at closing. You pay the same amount for the unit whether your occupancy period was two months or eighteen.
Functionally, you are renting your own future home from the builder. Hence the industry nickname: phantom rent.
The double-housing-cost problem
Here is the scenario that catches people. You are renting elsewhere with a lease running to a fixed date. Your occupancy date arrives earlier — or shifts — and now you are paying rent on your apartment and occupancy fees on the condo.
Pre-construction occupancy dates move. They move frequently and sometimes by a lot. Never sign a lease whose end date depends on an occupancy date the builder has given you as an estimate. Build in a buffer, or arrange a month-to-month tail.
What to do about it
Budget the full occupancy period as a genuine housing cost from the start. If you are treating the unit as an investment, model the occupancy period as a stretch where you carry the cost with no rental income unless your agreement specifically permits leasing during occupancy.
The bottom line: Occupancy fees buy you nothing except the right to live there early. Budget them as pure cost, and never assume you can rent the unit out during occupancy.
4How long it lasts — and why lower floors pay longest
There is no fixed length, and that uncertainty is itself the problem.
Typical range
Occupancy periods commonly run several months. In larger or delayed projects they can extend well beyond a year. Registration depends on construction completion, municipal sign-offs, and the surveying and legal work — any of which can slip.
The floor-level effect
Buildings are occupied from the bottom up as floors are completed. Registration happens once for the entire building.
So the person on the 4th floor may occupy many months before the person on the 40th, and both stop paying occupancy fees on the same day. Lower floors therefore pay occupancy fees for substantially longer.
This is worth factoring into your purchase decision. A lower floor is usually cheaper, but part of that saving can be consumed by a longer occupancy period. Ask the builder for their estimated first-occupancy date and their estimated registration date, and work out the gap for your specific floor.
The one useful question
Ask the builder what the occupancy period actually ran on their last two completed projects. Past delivery performance is far more informative than the projected dates in the disclosure statement, and a builder with a good record will be happy to answer.
The bottom line: Lower floors occupy first and stop paying at the same moment as everyone else, so they pay occupancy fees longest. Ask for both the occupancy and registration estimates and calculate your own gap.
5How to budget for it properly
Practical steps, in the order I would take them.
1. Model a long occupancy, not the projected one
Take the builder’s estimated occupancy fee and multiply by twelve months, not by the projected period. If the period comes in shorter, that is a windfall. If you have budgeted for the estimate and it doubles, that is a problem.
2. Consider a larger deposit
Because interest on the unpaid balance is usually the largest component, more deposit means a lower monthly fee. Weigh that against the opportunity cost of the cash and the fact that deposits are at risk if the project is cancelled.
3. Keep the occupancy budget separate from the closing budget
At final closing you still owe: the balance of the purchase price, land transfer taxes (both provincial and Toronto municipal), legal fees, development levies and closing adjustments. Occupancy fees paid in the meantime do not reduce any of that. People who spend their closing buffer on occupancy fees end up in trouble at the finish line.
4. Get your leasing rights in writing
If your plan depends on renting the unit during occupancy, that permission must be in the agreement. Do not assume. Many builders prohibit it and some charge for it.
5. Ask what the fee will actually be
Before you sign, ask the builder for an estimated occupancy fee for your specific unit at your specific deposit level. They can calculate it. Get it in writing and put it in your budget as a real monthly cost, alongside your current rent.
The bottom line: Budget twelve months of occupancy fees, keep that money separate from your closing costs, and get an estimated figure for your specific unit in writing before you sign.
Occupancy fee — what makes it up
| Component | What it is | Reduces your mortgage? | What affects it |
|---|---|---|---|
| Interest on unpaid balance | Interest on the portion of the price not yet paid | No | Deposit size — bigger deposit, smaller fee |
| Estimated property tax | Builder’s estimate of municipal tax on your unit | No | Reconciled at final closing |
| Projected common expenses | Builder’s projected monthly maintenance fee | No | Often exceeds projection after year one |
| Length of period | Move-in date to registration date | — | Your floor level; construction and registration delays |

Frequently asked questions
What is interim occupancy in a pre-construction condo?
Interim occupancy is the period between the date you move into your new condo unit and the date the condominium corporation legally registers, at which point title transfers to you and your mortgage funds. During this period you live in the unit but the builder still holds title, so you pay the builder a monthly occupancy fee instead of a mortgage payment. A building cannot register until it is substantially complete and the survey and legal work are approved, but units are occupied floor by floor as they are finished — which creates the gap.
How are occupancy fees calculated?
Occupancy fees have three components: interest on the unpaid balance of your purchase price, which is normally the largest part and is charged at a prescribed rather than discretionary rate; an estimate of the municipal property tax attributable to your unit; and the builder’s projection of your monthly common expenses, taken from the budget in the disclosure statement. Because interest on the unpaid balance dominates, a larger deposit directly reduces your monthly occupancy fee.
Do occupancy fees go toward my mortgage or purchase price?
No. Occupancy fees do not reduce your mortgage principal, are not credited against your purchase price, and do not lower what you owe at final closing. You pay the same total for the unit whether your occupancy period lasted two months or eighteen. This is why they are commonly called phantom rent — functionally you are renting your own future home from the builder.
How long does interim occupancy last in Toronto?
There is no fixed length. Occupancy periods commonly run several months and in larger or delayed projects can extend beyond a year, because registration depends on construction completion, municipal approvals and the surveying and legal work, any of which can slip. Importantly, buildings are occupied from the bottom up but register all at once, so lower-floor buyers occupy first and stop paying at the same moment as everyone else — meaning they pay occupancy fees for substantially longer. Ask the builder what the occupancy period actually ran on their last two completed projects.
Can I rent out my condo during interim occupancy?
It depends entirely on your agreement of purchase and sale. Many builders prohibit leasing during occupancy and some permit it only on payment of a fee. Do not assume the right exists — if your plan depends on rental income during the occupancy period, negotiate that permission into the contract before you sign. Investors who assume they can lease during occupancy and then find they cannot are left carrying the full monthly cost with no income against it.
How should I budget for occupancy fees?
Model twelve months of occupancy fees rather than the builder’s projected period, so a longer period is not a crisis. Consider a larger deposit, since interest on the unpaid balance is the largest component. Assume the actual maintenance fee will come in somewhat above the builder’s projection once the corporation has real operating history. And keep your occupancy budget entirely separate from your closing budget — at final closing you still owe the balance of the price, both provincial and Toronto municipal land transfer taxes, legal fees, development levies and closing adjustments, none of which occupancy fees reduce.
Interim occupancy is the period in a pre-construction condominium purchase between the buyer moving in and the condominium corporation legally registering, at which point title transfers and the mortgage funds. During interim occupancy the builder retains title and the buyer pays a monthly occupancy fee comprising three components: interest on the unpaid balance of the purchase price, which is usually the largest component and is charged at a prescribed rate; an estimate of municipal property tax for the unit; and the builder’s projected monthly common expenses. Occupancy fees do not reduce mortgage principal or the purchase price and are not credited at closing, which is why they are referred to as phantom rent. A larger deposit reduces the interest component and therefore the monthly fee. Occupancy periods commonly run several months and can exceed a year. Because buildings are occupied floor by floor but register all at once, lower-floor purchasers pay occupancy fees for significantly longer than upper-floor purchasers. Whether a unit may be leased during interim occupancy depends on the agreement of purchase and sale; many builders prohibit it. Buyers should budget approximately twelve months of occupancy fees separately from closing costs, which still include the balance of the purchase price, provincial and Toronto municipal land transfer taxes, legal fees and development levies.
