Buying New and Pre-Construction: Deposits, Delays, and Warranties

The glossy floor plan is not the protection

A new build can be a good fit: modern systems, warranty coverage, no bidding war, and a home chosen before it exists. But the risk sits in the documents. A sales centre can make a project feel finished long before the legal risk is finished.

The contract should answer the questions that matter: when deposits are due, whether deposits are protected, what happens if the closing or occupancy date moves, whether development charges can rise, whether you can assign the contract, whether finishes can change, and what happens if financing is harder at completion than at purchase.

New-home warranties are provincial systems

Ontario buyers often hear about Tarion. B.C. buyers often hear about 2-5-10 warranty insurance. Other provinces have their own systems or rules. The warranty can be valuable, but it is not a blank promise that every disappointment is covered. Warranties usually focus on construction defects, systems, building envelope, and structural problems within defined time windows and limits.

BC Housing describes the 2-5-10 structure as materials and labour coverage, building envelope coverage, and structural coverage, with limits and exclusions. That frame is useful even outside B.C.: know the covered defects, reporting deadlines, warranty provider, limits, and exclusions before you sign.

Use the lawyer before the deadline, not after

Many new-build contracts have short review windows. Do not use that time to keep browsing finishes. Use it to get legal review, mortgage advice, insurance advice, and clarity on the warranty authority. If the builder will not give you time to understand the contract, that is information.

Occupancy, closing, and possession can be different moments

Pre-construction buyers often talk about "the closing date" as if it is one clean event. In some projects, especially condos, there may be an occupancy period before final closing. You may be allowed to move in while title has not yet transferred, or you may owe interim occupancy costs before the final mortgage is in place. The exact words depend on province, property type, and contract.

This matters because your carrying cost can change before the home is fully yours. Rent, mortgage approval timing, interest rates, condo/strata fees, development charges, HST/GST treatment (including the new-build rebates in First-Time Home Buyer Programs), insurance, and moving dates can all collide. Ask the lawyer to translate every date into plain English: when can I move in, when does title transfer, when does the mortgage fund, what do I pay during the gap, and what happens if the builder misses a date?

If the answer is "that probably will not happen," keep asking until it is written in the contract.

The mortgage you qualify for today may not be the mortgage you need later

Pre-construction stretches time. Your income, debts, rates, family situation, immigration status, or lending rules can change before completion. A pre-approval now does not guarantee final approval for a specific unit years later. Ask your broker what must remain true at closing and what would make the lender reassess.

Also ask about assignment restrictions. If you cannot close and want to sell the contract, the builder may control whether assignment is allowed, what fee applies, and whether marketing is restricted. Treat assignment as a possible exit only after a lawyer confirms it in the contract.
