What are the legal risks of buying
pre-construction?
Shocking question reworded: What are the legal risks of buying pre-construction — and which ones will bankrupt Milton home sellers?
Quick answer up front
If you are a home seller in Milton, Ontario, and you’re thinking about buying pre-construction, the legal risks are real, predictable, and avoidable — but only if you know what to watch for in the contract and documentation. This post lays out the specific legal hazards for buyers and sellers in Milton ON real estate, the paperwork that matters, and the step-by-step protections you must demand.
Why this matters to Milton home sellers
You’re not just buying a future property — you’re entering a legal timeline: deposits, conditional sales, builder timelines, Tarion warranty rules, and the risk your resale might fall through while your new build is delayed. That chain reaction hits sellers hardest in Milton’s fast market. Know this now or pay later.
The 12 biggest legal risks of buying pre-construction (Milton focus)
Each item below includes what it means for buyers and what sellers in Milton must know.
- Deposit structure and forfeiture risk
- What it is: Large deposits paid in stages (initial + progress deposits) before title transfers. These are often non-refundable if you breach the purchase agreement.
- Buyer risk: You can lose tens of thousands if you fail to close or try to assign without permission.
- Seller angle: If you’re selling your home to buy pre-construction, you can’t rely on instant liquidation of funds. Structure your sale so deposit and closing dates align or secure bridge financing.
- Builder delays and occupancy adjustments
- What it is: Construction delays are common. Contracts often give builders broad rights to extend closing and occupancy dates.
- Buyer risk: You may be forced into temporary housing, incur storage costs, and face higher interest rates or double carrying costs.
- Seller angle: Don’t accept buyers who are tight to a moving date if they’re relying on a pre-construction closing. Ask for contractual protections or backup plans like rent-back clauses.
- Assignment clauses and resale restrictions
- What it is: Many pre-construction contracts restrict or prohibit assignment. Where allowed, builders may charge fees or require approval.
- Buyer risk: If you intended to flip or assign before closing, you could be blocked or penalized.
- Seller angle: If your buyer is purchasing pre-construction with an assignment intent, demand proof the builder allows assignment and confirm any fees in writing.
- Builder insolvency or change of control
- What it is: Builders go bankrupt or sell projects. The contract may allow the developer to transfer obligations.
- Buyer risk: Warranty claims and completion guarantees become unclear. Deposits might be unsecured.
- Seller angle: Insist on due diligence: review builder corporate structure, performance bonds (if any), and recent project history. If your buyer’s purchase depends on a risky builder, treat that offer with caution.
- Tarion warranty and warranty misstatements
- What it is: New homes in Ontario typically fall under Tarion warranty. But coverage varies by product and by whether the builder is enrolled properly.
- Buyer risk: Misunderstanding Tarion coverage leaves buyers exposed for defects, delays, or missing coverage.
- Seller angle: Verify the unit’s Tarion registration and what warranty applies. If a buyer claims Tarion protection for a deposit, confirm it.
- Zoning, site plan, and permit issues
- What it is: Municipal approvals can change. A development may face zoning appeals or permit delays affecting final product.
- Buyer risk: The finished building might differ from the model. Municipal hold-ups can delay occupancy.
- Seller angle: Check Milton’s planning notices for the project. If approvals are still pending, count that as a significant timing risk.
- Encumbrances, easements and title problems
- What it is: Land can carry easements, restrictive covenants, or unresolved title issues.
- Buyer risk: You might get a property with limited use or unexpected obligations.
- Seller angle: Ask for a status certificate or title search results before relying on a buyer’s closing timeline.
- Liens and unpaid contractor claims
- What it is: Subcontractors and suppliers can register liens against the property if unpaid.
- Buyer risk: A lien can block closing or reduce value.
- Seller angle: Confirm builder’s payment practices and insist on lien protection clauses or clear certificates of lien discharges before closing.
- Flawed or vague contract language
- What it is: Boilerplate clauses grant builders broad rights to change plans, finishes, or closing mechanics.
- Buyer risk: Vague phrasing gives builders leverage and limits buyer remedies.
- Seller angle: Review the buyer’s conditions tied to vague builder promises. If the buyer’s purchase depends on a subjective builder obligation, demand clarity or stronger buyer protections.
- HST, rebates and tax surprises
- What it is: HST on new purchases and rebates can change the cash flow at closing. Rules differ if the unit is owner-occupied vs. rental or resale.
- Buyer risk: Unexpected HST liabilities, delayed rebate payments, or taxable benefits increase closing costs.
- Seller angle: Confirm how HST or rebates affect the buyer’s funds and closing timing. Don’t accept offers that require complex tax adjustments without proof of planning.
- Financing conditions and appraisal gaps
- What it is: Lenders may appraise at a lower value than contract price and modern lenders impose terms for pre-construction financing.
- Buyer risk: Loan conditions at closing can kill the deal if value drops or lender requirements change.
- Seller angle: If your buyer’s financing is conditional on appraisal or sale of another home, secure contingency backstops or demand firm financing proof.
- Disclosure requirements and misrepresentation
- What it is: Builders and sellers must disclose material facts. Misrepresentations can lead to rescission or damages.
- Buyer risk: If a builder misrepresents square footage, finishes, or timing, legal claims are costly and slow.
- Seller angle: If you’re selling in Milton, ensure your listing disclosures don’t rely on the buyer’s pre-construction promises. Protect yourself from being pulled into litigation between buyer and builder.
Documentation you must get and review — a Milton checklist
Ask for and review these documents before you exchange contracts or accept an offer tied to pre-construction:
- Fully executed purchase agreement and builder addenda.
- Deposit schedule and trust accounting details.
- Tarion registration number and warranty documents.
- Builder’s disclosure statement and corporate background.
- Status of municipal approvals, site plan, and permits (Milton planning files).
- Assignment policy and form (if you plan to assign).
- Lien search or builder proof of payment to subcontractors.
- Insurance certificates (wrap-up insurance or builder’s risk insurance).
- Draft condominium declaration, by-laws, and budget (for condos).
- HST and rebate calculations and confirmation of accountant/tax advice.
Practical steps sellers in Milton must take now
This is where most agents fail: they assume buyers’ pre-construction promises are reliable. Don’t.
- Require firm closing dates or liquidated damages clauses on your sale.
- Accept offers contingent on buyer’s sale only with clear timelines and bridge financing proof.
- Verify builder reputation: recent completions, complaint history, and Tarion records.
- Add a clause that requires written evidence of builder permits and municipal approvals before you move out.
- Use a real estate lawyer experienced in Ontario pre-construction deals — insist on it in your conditional acceptance.
- Consider a backup offer if your buyer is buying pre-construction with long horizons.
Contract clauses to watch (and demand)
- Clear deposit refund triggers if closing doesn’t occur by a set date.
- Lien indemnity from builder or proof of lien searches before closing.
- Liquidated damages or rent-back options if occupancy is delayed.
- Explicit assignment permissions (if you want to assign).
- Detailed finish schedule and allowance amounts.
When to walk away
If the builder has a pattern of incomplete projects, unresolved municipal appeals, or no Tarion enrollment — walk. If a buyer’s offer depends on a builder with these red flags, don’t accept without strong legal protection.
