New construction

Before you sign for a new home.

Understand new-home agreements, deposits, HST, closing dates and warranty questions before buying in Seaton.

Reviewed 7 October 2026 · General planning guidance

Get the exact home on paper

Match the lot, model, elevation, floor area and included features across the documents. Model homes, renderings and staged rooms may include upgrades. Ask what substitutions the agreement permits.

Ask for a full cash schedule

List every deposit and closing payment with its due date. Request a breakdown of development charges, levies, adjustments, upgrades and other costs, including any caps that are actually written into the agreement.

Clarify HST and rebate assumptions

Two advertised prices may use different tax assumptions. Ask your lawyer how the agreement treats HST, who receives any rebate and what happens if you do not qualify. Rebate rules and eligibility are not safely reduced to a universal discount.

Understand timing and cancellation

Read the addendum and all dates with your lawyer. Delays, extensions, termination rights and occupancy arrangements depend on the contract and property type. HCRA has published requirements affecting certain freehold agreements from January 1, 2027; do not apply future rules to an earlier agreement without legal advice.

Check deposit protection limits

Tarion coverage has limits and conditions. For eligible freehold agreements, a $900,000 purchase can have a standard deposit-protection cap of $90,000, so a $180,000 deposit should not be assumed fully protected. Condominium deposit rules differ. Ask your lawyer to assess the actual protection.

Register and keep your warranty records

Check Tarion’s purchase-registration requirements and applicable deadlines for your agreement. Keep the agreement, receipts, inspection records and correspondence. Warranty submission windows depend on the possession date and applicable rules; use Tarion’s current forms and timelines rather than an old checklist.

Use the current official information.

Rules, forms and offers can change. Verify your agreement and eligibility with the relevant professional.
