Buying a New Build in Calgary: The Step-by-Step Process, Contracts & Warranty (2026)

How buying new construction differs from resale

Buying a newly built home in Calgary is a different process than purchasing a resale property, and understanding that difference is the single most important step. With a resale home you typically sign the standard residential purchase contract used across the province and negotiate with an existing owner. With new construction you usually sign the builder's own purchase agreement, which is drafted to protect the builder and can differ significantly from the resale contract you may have seen before.

These builder contracts often address things a resale contract never has to: construction timelines, completion (possession) date extensions, upgrade and change-order procedures, deposit schedules, and what happens if the home is not finished on time. Because the terms vary from builder to builder, you should read the entire agreement and consider having a real estate lawyer review it before you sign. For a broader overview of the new-construction landscape, see our expert guide to new build homes in Calgary.

Step 1: Get pre-approved and set your real budget

Before you visit a show home, speak with a mortgage professional about a pre-approval. New builds add a wrinkle most buyers don't expect: if your possession date is far in the future, your rate hold may expire before the home is ready, and lenders re-qualify you closer to completion. Confirm with your lender how long your rate is protected and what happens if rates or your financial situation change before possession.

Your budget also needs to account for more than the sticker price. Base prices advertised at show homes frequently exclude landscaping, fencing, window coverings, appliances, and upgrade packages. Build a realistic number that includes likely upgrades, GST (discussed below), and closing costs so you aren't surprised later.

Step 2: Understand the builder's purchase agreement

The purchase agreement is where most new-build risk lives. Pay close attention to these clauses before signing:

• Completion / possession date: Many builder contracts allow the builder to extend the completion date, sometimes more than once. Understand the outside date and your remedies if the home is delayed.
• Deposit structure: New builds often require deposits paid in stages. Confirm how much is at risk, when it is due, and whether your deposit is held in trust.
• Upgrades and change orders: Understand how upgrades are priced, when selections must be finalized, and whether prices can change.
• Price-adjustment and cancellation clauses: Some agreements permit the builder to adjust price or cancel under defined conditions. Know what they are.

These terms are contract-specific, so confirm the exact language with the builder and your lawyer rather than relying on general summaries.

Step 3: Deposits, financing, and the GST rebate

New homes in Canada are generally subject to 5% federal GST on the purchase price, unlike most resale homes. This is a real cost to budget for, though rebates may reduce it.

As of 2026, a federal First-Time Home Buyers' GST Rebate is in effect. Under Bill C-4, which received Royal Assent on March 12, 2026, eligible first-time buyers can receive a rebate that eliminates the federal GST on a qualifying new home valued up to $1 million, phased out on a straight-line basis between $1 million and $1.5 million, with no rebate at or above $1.5 million. The maximum benefit is up to $50,000, and eligibility generally requires that construction began on or after May 27, 2025. Program rules, eligibility, and deadlines are detailed and can change, so review our first-time buyer GST rebate guide and confirm your eligibility with a tax professional and the Canada Revenue Agency before relying on any rebate amount.

Step 4: Choosing a builder and community

Calgary has an active new-construction market across many master-planned communities, including established and emerging areas such as Livingston, Mahogany, Seton, Wolf Willow, and Glacier Ridge. Community developers set the overall plan and amenities, while individual home builders construct on the lots — the two roles are distinct, and it's worth understanding who is responsible for what.

When comparing builders such as Brookfield Residential, Jayman BUILT, Trico Homes, Cardel Homes, Morrison Homes, Excel Homes, or Mattamy Homes, treat any names here as informational reference points for your own research, not recommendations. Visit multiple show homes, ask for references, review each builder's registration in Alberta's public new-home registry, and read online reviews critically. Our Calgary home builders guide can help you organize that comparison. Builder and product names are trademarks of their respective owners and are used here for identification and comparison only; their appearance does not imply any partnership with, endorsement of, or representation of any builder by this brokerage.

Step 5: Alberta's mandatory new home warranty (1-2-5-10)

Under Alberta's New Home Buyer Protection Act, new homes with a building permit applied for on or after February 1, 2014 must carry mandatory warranty coverage backed by an approved warranty provider, and a new home cannot be sold or listed until it is registered in the New Home Buyer Protection public registry. This is one of the strongest consumer protections in new construction.

The mandatory minimum coverage follows the 1-2-5-10 model:

• 1 year on labour and materials;
• 2 years on delivery and distribution systems (such as electrical, plumbing, heating, and ventilation);
• 5 years on the building envelope, with the option for builders to purchase additional coverage;
• 10 years on major structural components.

Coverage is provided by approved warranty providers such as the Alberta New Home Warranty Program, National Home Warranty, and Progressive Home Warranty, among others. Coverage limits, exclusions, and claims procedures vary by provider, so confirm the specific policy, coverage cap, and exclusions directly with the builder and the named warranty provider. This is a summary only and is not legal or warranty advice.

Step 6: Pre-possession walkthrough and taking possession

Before possession, most builders schedule a pre-possession walkthrough (sometimes called an orientation) where you and the builder document deficiencies — incomplete or defective items — on a list the builder agrees to address. Take your time, test fixtures, and record everything in writing. Items noted here typically fall under your first-year labour-and-materials coverage.

On possession day, your lawyer handles the transfer and disbursement of funds, and you receive your keys. Keep your warranty documents, deficiency list, and builder contacts organized — you may need them during the warranty period.

Step 7: Budget for closing costs and consider representation

Beyond the purchase price and GST, budget for closing costs including legal fees, title insurance, an Alberta land title transfer registration fee, and adjustments. Our Calgary closing costs guide breaks these down so you can plan accurately.

You can be represented by your own real estate professional when buying new construction, even at a builder's show home. Working with a buyer's representative does not obligate you to the builder's sales staff, who represent the builder. If you engage a licensee, real estate commissions in Alberta are negotiable and are not fixed by law, by RECA, or by any real estate board — there is no mandated or "standard" rate, and any fee arrangement is set between you and the professional you hire. Service models also vary: some professionals offer full-service representation while others offer flat-fee or limited-service options, and the scope of services included can differ meaningfully between them. Compare what is and isn't included rather than price alone, and confirm the terms in writing. If you'd like to discuss representation for a new build, get in touch.
