New Build vs Resale in Calgary (2026): Costs, Warranty, GST and Which Is Right for You
Updated November 2, 2026 · Written by Justin Warthe, Team Lead, The Top Calgary Real Estate Team
Calgary builders are selling hard in 2026, and resale sellers are competing with them street by street in Seton, Livingston, Cornerstone, Rangeview and every new community on the edges. For a buyer the question is not which is better in the abstract; it is which is better for your budget, your timeline and your tolerance for surprises. Here is an honest comparison, including the costs that show up only after possession.
Quick answer: New builds give you a warranty, modern code and layouts, and a price that often looks lower per square foot; resale gives you a finished lot, mature trees, a known neighbourhood and a home you can inspect and move into in weeks. The hidden costs decide it: GST on a new build (rebates may reduce it, including the new first-time buyer rebate on homes up to $1 million for qualifying buyers), landscaping, fencing, window coverings, a supplementary property tax bill and a possession date that can move; on resale, the age of the roof, furnace and windows and the Real Property Report. We represent buyers with every Calgary builder at no cost to the buyer and we sell resale in the same communities, so we will show you both and let the numbers decide. Book a call.
Key takeaways
- Builders pay the buyer's agent, so bringing your own REALTOR® to a show home costs you nothing and gets you representation on the contract, the upgrades and the deposit structure; register us on your first visit, not your second.
- GST applies to new homes at 5%. The long-standing GST new housing rebate covers part of it on lower-priced homes, and the federal First-Time Home Buyers' GST rebate (for qualifying first-time buyers on agreements signed after May 27, 2025) can eliminate the GST on a new home up to $1 million, phasing out to $1.5 million. Eligibility is determined by the Canada Revenue Agency; ask your accountant.
- Alberta's New Home Buyer Protection Act requires warranty coverage on new homes: one year on labour and materials, two years on delivery and distribution systems, five years on the building envelope and ten years on the structure, with the option to extend some coverage.
- Resale is the only option in most established communities, and in September 2026 the CREB® detached benchmark was $739,400 with just over three months of supply, while apartment and row supply is heaviest where new construction has been concentrated.
The side-by-side
| Factor | New build | Resale |
|---|---|---|
| Price | Base price plus lot premium, upgrades, GST; incentives common in 2026 | Negotiated from list; sold at about 97% of asking on average in September 2026 |
| Timing | Typically 8 to 14 months for a full build; quick possessions available | Possession in 30 to 90 days |
| Warranty | Alberta 1-2-5-10 warranty mandatory | None, except any remaining builder warranty on a newer home |
| Inspection | Pre-possession walkthrough and deficiency list; a private inspection is still worth it | Full inspection as a condition of the offer |
| Lot and landscaping | Often bare: budget for grading, sod, trees, fencing, deck | Done, and mature |
| Property tax | First bill may cover land only, then a supplementary bill for the house | Full-year bill adjusted at closing |
| Real Property Report | Provided by the builder at possession in most contracts | Seller provides a current RPR with compliance |
| Location | New communities on the edges; longer commutes until roads and transit catch up | Established communities, schools and transit |
| Energy and layout | Current code, open plans, better envelopes | Varies; older mechanical systems may need replacement |
| Surprises | Delayed possession, construction around you for years, extra costs after possession | Age-related repairs; a wrong-priced listing |
General comparison; every builder contract and every resale home is different.
What buyers forget on a new build
- GST and rebates. The sticker price may or may not include GST; ask. Rebates reduce the net cost but have conditions, and the first-time buyer rebate has age, residency and occupancy requirements and applies only to agreements signed after May 27, 2025.
- Deposits and the contract. Builder contracts are not the Alberta standard contract. Deposits are often staged, upgrades are paid up front and rarely refundable, and possession dates can move. Have a lawyer review the contract before you sign.
- After-possession costs. Landscaping deposits and deadlines, fencing, window coverings, a deck, a finished basement, appliances in some contracts, and the supplementary property tax bill when the City assesses the completed house.
- Resale value. You will compete with the builder's next phase for years. Choose lots and models that resell well and avoid paying for upgrades that the market does not reward.
What buyers forget on a resale
- Big-ticket systems. Roof, furnace, hot water tank, windows and in older homes the electrical panel and sewer line. The inspection and our comparable sales tell you what is priced in and what is not.
- The RPR and permits. A deck, garage or suite without permits becomes your problem after closing unless it is dealt with in the contract.
- Condo documents on any resale condo or townhouse: reserve fund, minutes, insurance.
- Competition. Well-priced resale detached homes under $700,000 in established areas still draw multiple offers in 2026, so be ready to move quickly with a pre-approval in hand.

Frequently asked questions
Is it cheaper to buy a new build or a resale in Calgary?
On paper new builds often look cheaper per square foot, but GST, lot premiums, upgrades, landscaping, fencing, window coverings and a supplementary tax bill add up after possession. Resale homes come finished but may need big-ticket systems replaced. We run the full cost of both before you decide.
Do I pay GST on a new home in Alberta?
Yes, 5% GST applies to new homes. The GST new housing rebate reduces it on lower-priced homes, and qualifying first-time buyers may be eligible for the federal First-Time Home Buyers' GST rebate on new homes up to $1 million (phasing out to $1.5 million) for agreements signed after May 27, 2025. The Canada Revenue Agency determines eligibility; ask your accountant.
What warranty comes with a new home in Alberta?
Alberta's New Home Buyer Protection Act requires warranty coverage of one year on labour and materials, two years on delivery and distribution systems, five years on the building envelope and ten years on the structure.
Do I need a REALTOR® to buy from a builder?
No, but you should have one. The builder pays the buyer's agent, so representation costs you nothing, and you get advice on the contract, the deposit structure, upgrades and resale value. Register your agent on your first show-home visit.
Should I get an inspection on a new build?
Yes. The builder's walkthrough catches cosmetic deficiencies; a private inspection before possession and again before the one-year warranty expires catches the rest.
