Interim Occupancy and Occupancy Fees in Ontario, Explained

Interim occupancy is the stretch of time when you can move into a new pre-construction condo, or rent it out, before the building is registered and title actually transfers to you. During that period you pay the builder a monthly occupancy fee. The fee is made up of three parts: interest on the unpaid balance of your purchase price, an estimate of the municipal property taxes on your unit, and an estimate of your share of the building's common expenses. It is not a mortgage payment, and none of it reduces what you owe on the home.

This is one of the most misunderstood parts of buying a pre-construction condo, and it is the question buyers ask us most once their occupancy date is set. Here is how it works.

Why interim occupancy exists

Interim occupancy exists because a condo unit is usually ready to live in before the whole building is legally finished. You cannot get a mortgage and take title to a unit until the condominium corporation is registered, which happens after the building is substantially complete and the city signs off. But the developer wants to hand over finished units, and buyers want to move in.

The answer is interim occupancy: you take possession of your unit and start living in it (or leasing it, if your agreement allows), while the building finishes and works toward registration. Because you do not own the unit yet, you cannot pay a mortgage on it. Instead you pay the builder to occupy it.

What the occupancy fee is made of

Under Ontario's Condominium Act, 1998, the monthly occupancy fee has three components, and only three:

1. Interest on the unpaid balance of the purchase price, at a rate set by the Act. This is usually the largest part of the fee. The rate is tied to the Bank of Canada's posted rate for conventional one-year mortgages, so a higher unpaid balance and a higher rate both push the fee up.
2. An estimate of the municipal property taxes attributable to your unit.
3. An estimate of your share of the building's common expenses (the condo maintenance fees).

Because the tax and common-expense pieces are estimates, they can be adjusted once real figures are known. The Condominium Act, 1998 is the governing legislation, and a builder cannot invent extra charges beyond these three.

The builder is not allowed to profit from it

This is worth knowing. The occupancy fee is meant to cover the carrying cost of your unit during interim occupancy, not to make the developer money. Legal commentary on the Act notes that builders are prohibited from profiting from occupancy fees. In plain terms, the fee is closer to rent that reflects the builder's real costs than to a fee they can set at will.

Why it is not a mortgage payment

Here is the part that stings. Your occupancy fee does not build any ownership. None of it goes toward your principal, and the interest portion is not mortgage interest you can treat the usual way. You are paying to live in a home you do not yet own, and the money is gone once paid.

That matters for two reasons. First, you are effectively carrying two housing costs in your budget: the occupancy fee now, and your real mortgage later once you close. Second, buyers who assumed occupancy fees were an early start on the mortgage are often surprised at final closing to find their balance is exactly what it was before. Plan for the fee as a separate, non-recoverable cost.

How long interim occupancy lasts

It varies a lot. On a low-rise or a small building, interim occupancy might last only a few weeks. On a large high-rise, where lower-floor units are occupied while upper floors and common areas are still being finished, it can run many months and sometimes more than a year. The length depends on how far along the building is when your unit is ready and how quickly the corporation registers.

In our experience the buyers most exposed are those on lower floors of tall towers, because they move in early and then pay occupancy fees for the whole time it takes the rest of the building to finish. When you are choosing a unit, ask the builder for their best estimate of the occupancy period and budget for the high end.

Occupancy fees versus renting

Buyers sometimes ask whether they would be better off just renting until closing. Occupancy fees and rent are alike in one way and different in another. Both are money you do not get back, and neither builds equity. But during interim occupancy you are living in the exact home you have already committed to buy, you have usually chosen your own finishes, and you cannot be asked to leave the way a tenant can. The downside is that you are carrying the unit at the builder's cost of money, which in a higher-rate period can run more than the market rent on a comparable unit. There is no single right answer. It depends on the interest rate, your unpaid balance, and how long the interim period is expected to last, which is exactly why it is worth doing the math on your specific unit before you sign.

Interim occupancy and your warranty clock

One detail that catches condo buyers: for the Tarion new-home warranty, your possession date is the start of interim occupancy, not final closing. So the one-year warranty period often begins while you are still paying occupancy fees and waiting to close. Take your pre-delivery inspection seriously and diarize your warranty dates from the day you move in. Our guide to the Tarion warranty covers those timelines.

How to plan for it

A few habits keep interim occupancy from becoming a nasty surprise:

• Ask for the estimated occupancy date and the estimated fee in writing before you sign, and treat both as estimates that can move.
• Budget the occupancy fee as its own line item on top of your deposit and closing costs. It does not reduce your mortgage.
• Remember the interest portion moves with rates, so a fee quoted years ago at signing may look different by the time you occupy.
• Have your real estate lawyer review the occupancy and closing provisions early, alongside the deposit structure and the other closing costs.

Where we fit in

We represent the buyer, never the developer. Before you sign, we read the occupancy and closing sections, flag how long the interim period might run, and make sure the fee is in your budget as a real cost, not mistaken for an early mortgage. It is unglamorous work that saves confusion and money at closing.
