Calgary new builds offer modern energy ratings, full new-home warranty, and lock-in pricing 6-18 months ahead of completion — but come with 5% GST, a partial federal first-home rebate, and the real risk of build-quality variance between builders. The right new build at the right price beats a tired resale; the wrong builder at any price is a five-year headache. This guide names the Calgary builders worth shortlisting and the math that decides whether new beats resale at your price point.
The GST math for Calgary new builds
New construction triggers 5% GST on the purchase price. The federal new-home rebate refunds a portion: full 36% rebate on the first $350K of base price, declining to zero at $450K. Above $450K, no federal rebate. For a $700K new build, you're paying ~$28K in GST after rebate — bake it into your affordability math or negotiate it from the builder. Many builders advertise "GST included" pricing, which means it's already in the ticket price.
What new-home warranty actually covers
Alberta new-home warranty (mandatory) covers: 1 year labour + materials, 2 years delivery + distribution systems (plumbing, electrical, HVAC), 5 years building envelope (roof, exterior walls), 10 years structural defects. The warranty does NOT cover settling cracks, normal wear, or homeowner-caused damage. Always register the warranty within 30 days of possession and document any deficiencies during the 12-month inspection.

Frequently Asked Questions
Is GST included in Calgary new build pricing?
It depends on the builder. Always ask directly: "Is the quoted price GST-inclusive or plus GST?" Many builders advertise GST-inclusive pricing to simplify the consumer math. The federal new-home rebate at $350K base price is approximately $6,300; declining to zero at $450K base.
What's the typical Calgary new build deposit?
$10K-$25K initial deposit, with another $10-25K at firm-deal stage (lot release + plans approved). Some builders structure deposits as 5% of purchase price total. The deposit is held in trust per Alberta consumer protection; you can't lose it unless you breach the contract.
How long does a Calgary new build take?
Pre-construction to possession: 9-18 months typical, 24+ for premium custom builds. Your mortgage rate hold is usually 90-120 days, so timing the rate-lock to actual completion (not contract signing) is critical. Most builders provide a possession window (e.g. "Q2 2027") rather than a specific date.
