Interim occupancy is the period between the day the builder lets you move into a new condominium unit and the day the corporation is registered and title actually transfers to you. During it you pay a monthly occupancy fee made up of three parts: interest on the unpaid balance of the purchase price, an estimated share of municipal property tax, and an estimated share of common expenses. Your mortgage has not advanced, so none of that money reduces a loan or builds equity. It is a real cost, it can run for months, and it must be budgeted for separately.
Why the phase exists at all
A condominium unit cannot be conveyed to you until the condominium corporation is registered, and registration cannot happen until the building has satisfied the requirements to be described and registered as a corporation — surveys, plans, approvals and the developer’s own process. Construction, meanwhile, finishes floor by floor from the bottom up.
The practical result is that a building can be ready enough for people to live in on the lower floors long before it is ready to be registered. Rather than leave the building empty for months, the framework allows purchasers to take occupancy in advance of closing, on the terms set out in their agreement of purchase and sale. In exchange, the purchaser compensates the developer for occupying a unit they have not yet paid for.
That is the whole logic of the occupancy fee. It is not rent, it is not a penalty, and it is not equity.
What the monthly fee is made of
| Component | What it is | Roughly how large |
|---|---|---|
| Interest on the unpaid balance | Interest on the portion of the purchase price you have not yet paid, at the rate provided for under the legislation and the agreement | Usually the largest of the three |
| Estimated municipal property tax | The developer’s estimate of the unit’s share, since the unit is not separately assessed yet | Moderate |
| Estimated common expenses | The projected monthly common expense contribution for the unit | Roughly what the fee will be after registration |
Two things follow that people find genuinely surprising the first time.
First, none of it touches your mortgage. Your lender does not advance funds until final closing, so there is no principal, no amortisation and no equity. If you are used to thinking of a housing payment as partly saving, this one is not.
Second, the property tax and common expense components are estimates. They can be adjusted at final closing when the real numbers are known, in either direction, and that adjustment appears on the statement of adjustments alongside everything else.
How long it lasts
Anywhere from a few weeks to well over a year, and it is not something the builder can tell you precisely at the start, because registration depends on approvals outside their control. Lower floors occupy first and therefore pay longest; the top floors may occupy only weeks before registration.
Two consequences for planning:
- Budget for the phase, not for a date. If you can absorb twelve months of occupancy fees without strain, you are safe. If four months would break you, the risk is real.
- Floor choice has a cash-flow dimension. A lower-floor purchaser in a tall building can pay occupancy fees substantially longer than a top-floor purchaser in the same building.

What you can and cannot do during occupancy
| You can | You cannot |
|---|---|
| Live in the unit | Register a mortgage — you do not have title yet |
| Use the amenities the builder has released | Assume all amenities are open; many are finished last |
| Do your pre-delivery inspection and file warranty items | Renovate or make structural changes |
| Rent the unit out, if your agreement permits it | Assume you may rent it; many agreements restrict occupancy-period leasing or charge a fee |
| Vote at the first owners’ meeting once registered | Vote as an owner before registration — there is no corporation yet |
| Sell by assignment, if your agreement permits it | Assume assignment is free; assignment fees and consent requirements are common |
Read the occupancy provisions of your agreement before the phase begins, not during it. Leasing and assignment are the two areas where purchasers most often assume a right they do not have.
The pre-delivery inspection matters more than people think
Before you take occupancy you will do a pre-delivery inspection with the builder. This is your structured opportunity to document what is incomplete or defective, and it feeds the new home warranty process administered under Ontario’s new home warranty framework.
Practical advice:
- Bring somebody methodical with you, and allow more time than the builder suggests.
- Photograph everything, including the items you are told will be fixed.
- Write down items even when the representative says they will handle it informally. If it is not on the form, it is not on the record.
- Test everything that turns on: every outlet, every tap, the HVAC in both modes, every window and every door.
- Check the finishes against what your agreement and your finish selections actually specified.
- Keep your copy. You will need it during the warranty period.
Final closing: what changes
When the corporation is registered, final closing follows. On that day:
- Title transfers to you and your mortgage advances and is registered.
- Occupancy fees stop, and regular common expenses begin.
- Land transfer tax becomes payable — in Etobicoke, both the provincial tax and the Toronto Municipal Land Transfer Tax, in cash.
- The builder’s closing adjustments land: development and education levies, utility connection and meter charges, the new home warranty enrolment fee, and the reconciliation of the estimated property tax and common expense components you have been paying.
- HST and the new housing rebate are settled according to whether you are occupying the unit or renting it out. If your intention changed during occupancy, tell your lawyer early — the amounts involved are large.
How to plan for it properly
- Ask the builder, in writing, for their current estimate of both the occupancy date and the registration date. Treat both as estimates.
- Ask for an estimate of the monthly occupancy fee for your specific unit, broken into its three components.
- Multiply by twelve. If that number is survivable, proceed with confidence.
- Confirm in writing whether you may lease the unit during occupancy, and on what terms.
- Confirm the assignment provisions and any fee.
- Ask whether the agreement caps development and education levies, and at what amount.
- Get the HST question answered in writing based on your actual intention.
- Keep your rate hold alive, and stay in contact with your mortgage broker — a registration date that slips past your hold means requalifying at whatever rates exist then.
Etobicoke context
The Queensway, Humber Bay Shores, Mimico and Islington City Centre have all delivered substantial new condominium supply, and every one of those buildings went through this phase. Purchasers on lower floors of the taller Humber Bay towers in particular have historically carried occupancy for extended periods, simply as a function of building height and registration timing.
If you are buying resale in a very new Etobicoke building, this history matters to you too: ask when the corporation was registered, because a building in its first year or two has a reserve fund still in early accumulation and a budget that has not yet been tested by a full operating cycle.
Frequently asked questions
What is interim occupancy?
The period between moving into a new condominium unit and the day title actually transfers to you, which cannot happen until the condominium corporation is registered. You live in the unit and pay a monthly occupancy fee to the developer, but you are not yet the registered owner and your mortgage has not advanced.
What does the occupancy fee cover?
Three components: interest on the unpaid balance of the purchase price, an estimated share of municipal property tax, and an estimated share of the unit’s common expenses. The interest portion is usually the largest. None of the payment reduces mortgage principal, because there is no mortgage yet.
Does the occupancy fee build any equity?
No. Your lender does not advance funds until final closing, so there is no principal being repaid and no equity accruing. It is best understood as a carrying cost for occupying a unit you have not yet paid for — a real expense that has to be budgeted separately from your down payment and closing costs.
How long does interim occupancy last in Ontario?
Anywhere from a few weeks to more than a year. It depends on when your floor is released for occupancy and when the corporation is registered, and registration timing depends on approvals outside the builder’s control. Lower floors occupy first and therefore usually pay longest. Budget as though it could run twelve months.
Can I rent out my unit during interim occupancy?
Only if your agreement of purchase and sale permits it. Many agreements restrict leasing during the occupancy period, require the builder’s consent, or charge a fee. Do not assume the right exists — check the occupancy provisions in your agreement before you make plans, and get any permission in writing.
Are occupancy fees negotiable?
The structure is not, because it flows from the legislation and the agreement you signed. What is sometimes negotiable at the time of purchase is a cap on the occupancy period, a cap on development and education levies, or an occupancy fee credit — but those are pre-signing negotiations, not conversations to have once you are in the unit.
What happens at final closing?
Title transfers, your mortgage advances and is registered, occupancy fees stop and regular common expenses begin. Land transfer tax becomes payable in cash — both provincial and Toronto municipal in Etobicoke — along with the builder’s closing adjustments: development and education levies, utility connection and meter charges, the warranty enrolment fee, and the reconciliation of the estimated tax and common expense amounts you paid during occupancy.
What if my mortgage rate hold expires before registration?
You requalify at whatever rates and rules exist then, which is one of the underappreciated risks of a long occupancy period. Stay in contact with your mortgage broker throughout, ask about extended rate holds designed for new construction, and tell them immediately if the builder revises the registration estimate.
