The excitement of buying a newly built home often centres on the finished space – the layout, the light, the idea of being the first to live there. Less visible, but just as important, are the rules, protections and responsibilities that shape the experience from the day you put down your deposit.

We always advise buyers to follow these six tips early to feel more prepared, avoid surprises, and move forward with confidence as they make one of the biggest purchases of their lives.

1. Seek legal advice

New-home contracts are often lengthy and can include clauses about deposits, closing adjustments, construction timelines and changes to the home. A lawyer with experience in new home construction can walk you through what those terms mean and flag anything that may need clarification before you commit.

2. Research the builder

In Ontario, new homes can only be sold by builders and vendors licensed by the Home Construction Regulatory Authority (HCRA). You should always check the licence status and warranty history, which are publicly available through the HCRA’s Ontario Builder Directory, of any builder that you are considering purchasing a home from. Beyond this, look at online reviews or talk with past purchasers – a few real-world perspectives can help round out the picture and give you an idea of the customer service your builder could provide.

3. Understand what’s included and what costs extra

Floorplans, renderings and other promotional materials may show features or finishes that are optional or available at additional cost. When finalizing your agreement, ask for floorplans, specifications and materials lists in writing, and clarify what’s standard versus optional. It’s also smart to understand completion timelines in the Addendum to your purchase agreement, and how delays are communicated, especially if your move-in schedule is tied to a lease or a sale.

4. Register your purchase agreement with Tarion

Once the agreement is signed, registering it with Tarion is a simple step that can make a difference later. It helps ensure your deposit is protected, notifies Tarion of the sale, and gives homeowners access to warranty information and tools early – at a point when it’s easy to familiarize yourself with the coverage, rather than trying to catch up after you move-in.

5. Prepare for your pre-delivery inspection

Before you move in, you’ll complete a pre-delivery inspection (PDI). This is a walkthrough of the home with the builder that also involves learning how things work. You can take a checklist (there’s a handy one available on Tarion’s website), take photos and note any unfinished or damaged items. You don’t need construction experience – just attention to detail.

6. Understand your warranty

All new homes in Ontario come with warranty coverage across multiple years: one year for workmanship and materials, two years for your home’s systems, and seven years for major structural defects. Knowing what’s covered – and when – makes it easier to act if issues arise. In most cases, warranty timelines begin when you get your keys. For some homes, this can occur before construction is fully complete. Through Tarion’s MyHome portal, homeowners can register their warranty, submit or manage your warranty claims, and track these important timelines.

A newly built home brings a lot of excitement, along with plenty to take in. From the paperwork to the final walk-through, knowing how the process works can take some of the guesswork out of buying new. And if you have questions along the way – or after possession – Tarion is here to help.
