What is interim occupancy on a pre-construction condo?

By Oben Necip  ·  VP of Sales and New Developments, Broker

Buyers who sign for a new condominium often expect one closing day, and typically get two.

Interim occupancy is the stretch when you can live in a new condominium before you own it. The Condominium Authority of Ontario says ownership can only be transferred once the condominium corporation has been registered. Until that happens you pay the builder a monthly occupancy fee, and you make no mortgage payments at all.

Below we cover what that fee is built from and how long the period runs. We also cover the warranty and what to settle before you sign.

What is interim occupancy?

It is the period when a builder lets you move in before title can change hands.

The Condominium Authority of Ontario describes it as what happens “when the builder lets the buyer take occupancy” of a unit in a pre-construction project. The building is finished enough to live in. The paperwork that creates the condominium corporation is not finished yet.

Registration is the step that releases ownership. The authority says ownership can only be transferred once the condominium corporation has been registered with the Land Registry Office.

So you get the keys first and title later. Title is transferred to you at final closing, which is a separate date with its own set of costs.

One consequence surprises nearly every first-time buyer. A buyer “cannot make mortgage payments until the condo corporation is registered,” on the same guidance. Your mortgage has not started, so nothing you pay in this period reduces it.

What does the occupancy fee cover?

Three things, and the authority sets a ceiling on the total.

The occupancy fee “cannot be more than the total of” three amounts. The first is interest, calculated monthly, on the unpaid balance of the purchase price at the prescribed interest rate. The second is the estimated monthly municipal taxes for the unit. The third is the projected common expenses for the unit.

Three words in there are worth unpacking. Prescribed means the rate set out in the regulations. Common expenses are the monthly condominium fees that pay for shared costs. Projected means the builder’s estimate, usually taken from the first-year budget in the disclosure statement, because the building has no operating history yet.

Read the interest line closely, because it is often the largest of the three. It is interest on what you still owe the builder, which is the purchase price less the deposits you have already paid.

The fee is due whether or not you move in. The authority is explicit that a buyer pays it “regardless of whether they move into the condo unit or not.” Anyone planning to rent the unit out in this period should read the agreement first, because builders set their own terms on leasing before registration.

How long does interim occupancy last?

Until the condominium corporation is registered, and no calendar can tell you that date in advance.

The Condominium Authority of Ontario ties the transfer of ownership to registration and does not put a length on the wait. The date turns on the municipality, the surveyor, the lawyers and the state of the building.

What you can pin down is the occupancy date itself. Tarion, which administers Ontario’s new home warranty, sets rules for how a builder schedules that date and changes it.

A First Tentative Occupancy Date is the date the builder expects the home to be ready. A builder who needs to move it must give written notice “at least 90 days before the First Tentative Occupancy Date,” on Tarion’s guidance. Each later extension needs the same 90 days of notice.

The tentative dates give way to a Firm Occupancy Date, the one the builder commits to. Tarion says the builder must set a Final Tentative Occupancy Date within 30 days of roof completion, on at least 90 days written notice. If the builder cannot meet that date, Tarion allows one last extension of up to 120 days. The builder sets a Firm Occupancy Date, again on 90 days written notice.

Your agreement also carries an Outside Occupancy Date, the latest date the builder agreed to give you occupancy. If the unit is not ready by then, Tarion says you have 30 days to terminate the agreement by written notice to the builder.

Ask for those dates in writing before you sign. They are the difference between a wait you can plan around and one you cannot.

What does the warranty cover if your date moves?

It depends on which date moves.

A tentative date can be pushed back without compensation, provided the builder gives the required notice and stays inside the Outside Occupancy Date. Compensation starts when the builder misses the Firm Occupancy Date.

At that point the builder owes delayed occupancy compensation, to a maximum of $7,500 under the warranty. That total includes $150 a day for living expenses, and Tarion does not ask for receipts for the daily amount. Other costs caused by the delay, such as moving and storage, can be claimed inside the same maximum with receipts.

Notice carries its own consequence. A builder has to give at least 10 days written notice of a delayed occupancy date. Tarion says missing it adds 10 more days of compensation, or $1,500 at the daily rate.

Two exceptions are worth knowing. Compensation does not apply where both sides agreed to extend the date, or where the delay was unavoidable. A signed extension can therefore give up money you were owed, so read any request for one with your lawyer.

Timing matters as well. Tarion asks a purchaser to claim against the builder as soon as practicable after occupancy. A claim can be submitted to Tarion itself within one year of taking occupancy.

Deposits have separate cover. Condominium deposits must be held in trust under the Condominium Act, on Tarion’s guidance. Tarion also provides deposit protection “of up to $20,000 plus a limited amount of interest that has accrued.” Ask your lawyer how your own deposits are held, because your agreement matters here as well.

What should you settle before you sign?

Read the disclosure statement, and use the days the rules give you.

Your agreement is not binding the moment you sign it. The Condominium Authority of Ontario says the agreement “is not binding until you receive both the disclosure statement” and Ontario’s Residential Condominium Buyers’ Guide. Both come from the builder.

The disclosure statement is where the numbers live. It holds the proposed declaration, by-laws and rules, on the authority’s description. It also holds a summary of the agreements the builder will enter into before the turn-over meeting. The budget statement for the first year after registration is in there too. That budget is the source of the projected common expenses in your occupancy fee.

The authority describes a turn-over meeting as the point where the developer turns the corporation over to an owner-elected board. It happens once half the units have been sold and transferred to owners. Until then, the builder is running the corporation you are buying into.

Then there is a window to change your mind. Purchasers have “a 10-day cooling off period in which they may rescind their agreement of purchase and sale.” A later material change to the information in the disclosure statement can also give a purchaser a right to rescind, meaning to cancel the deal. Speak to your lawyer promptly if that happens, because the authority does not publish how long that right lasts.

Financing deserves an early conversation. Your lender looks at the unit when the mortgage funds at final closing, which can be years after you signed.

Values move over a gap like that. The Toronto Regional Real Estate Board puts the September 2026 apartment benchmark price for All TRREB Areas at $527,200. That is down 6.7% over the year. A benchmark price tracks a typical unit over time rather than averaging whatever happened to sell. That figure covers all TRREB areas, so other markets such as Waterloo Region will read differently.

Have a real estate lawyer read the agreement inside the cooling off period. That is the point where a question can still change something.

Quick Questions

Do you pay a mortgage during interim occupancy in Ontario? No. The Condominium Authority of Ontario says a buyer cannot make mortgage payments until the condominium corporation is registered. You pay the builder a monthly occupancy fee instead, and none of it reduces your mortgage balance.

What is included in an interim occupancy fee? The Condominium Authority of Ontario says the fee cannot be more than the total of three amounts. Those are monthly interest on the unpaid balance of the purchase price, the estimated monthly municipal taxes, and the projected common expenses for the unit.

How long does interim occupancy last in Ontario? It runs until the condominium corporation is registered, and the authority does not set a length for it. The date depends on the building and on the registration process, so ask your builder and your lawyer what the project is working towards.

What happens if your condo occupancy date is delayed? It depends on which date moves. A tentative date can move without compensation if the builder gives the notice Tarion requires. If the builder misses the Firm Occupancy Date, compensation runs to a maximum of $7,500, including $150 a day for living expenses.
