Building a Home in Ottawa? Here's How Construction Mortgages Work

Construction Mortgage vs. a Regular Mortgage

When you buy a completed home, a standard mortgage funds the purchase on closing day — the lender transfers funds, you take ownership, and you begin repaying principal and interest. A construction mortgage works differently. Because the home doesn't exist yet, the lender can't value a completed property and won't fund the full amount upfront. Instead, funds are advanced in stages as construction progresses. This staged release is called a draw schedule.

How the Draw Schedule Works

In a typical Ottawa new construction project, the mortgage is advanced in three to five draws tied to construction milestones. These commonly include:

• Foundation draw: Released when the foundation is complete and inspected
• Lock-up draw: Released when the structure is framed, windows and doors installed, and the home is weathertight
• Drywall draw: Released when interior drywalling is complete
• Occupancy draw: Released when the occupancy permit is issued

Between draws, you pay interest only on the amount advanced — not the full mortgage amount. This means your costs during construction are lower than a full mortgage payment, but the draw amounts need to be carefully timed with your builder's billing schedule.

Builder Agreement Review — Why It Matters Before You Sign

New construction purchase agreements in Ottawa include clauses that can have significant mortgage implications: deposit structures, upgrade allowance limitations, closing date adjustment provisions, and assignment restrictions. Reviewing your builder agreement with a mortgage professional before you sign ensures that nothing in the contract creates problems with your financing. Jessy reviews builder agreements for Stittsville, Barrhaven, Kanata, and across Ottawa — at no charge — before clients sign.

What You Need to Qualify

• Approved builder: Not all builders are accepted by all lenders. Jessy confirms builder acceptance before the file is structured.
• Building permit: Lenders require a valid building permit before advancing construction funds.
• Fixed-price contract: Lenders need a fixed contract price. Cost-plus contracts create underwriting complexity.
• Property details: Lot purchase documentation if the land is already owned, or a lot reservation agreement for new subdivisions.
• Standard mortgage qualification: Income, credit, and down payment requirements apply the same as a regular mortgage.

Ottawa's Active New Build Communities

Stittsville and Barrhaven have the highest volume of active new construction in Ottawa. Fairwinds, Poole Creek, and Westcliffe Estates in Stittsville are seeing hundreds of new units per year. Half Moon Bay and Rideau Pointe in Barrhaven continue to grow. On the east side, Cardinal Creek Village in Orléans remains active. Kanata's Fernbank Urban Community is also in active development with multiple builders.

Rate Holds and Build Timelines

Ottawa new construction build times typically run 12–24 months from signing to occupancy. Standard mortgage rate holds cover 90–120 days — which means a rate locked when you sign your purchase agreement won't survive to your closing date. Jessy manages the rate hold strategy throughout your build, extending and refreshing holds as needed to protect your rate as construction progresses.

Getting Started

If you're planning to build or have already signed with an Ottawa builder, the earlier you involve a mortgage broker, the better your outcome. Builder agreements, deposit schedules, and upgrade decisions all interact with your financing in ways that are easier to manage proactively.
