Quick Reference

5 Things Every Ontario Home Builder Should Know

01 — Get Tarion Registered

Any builder constructing a new home in Ontario must be registered with Tarion. Always verify before signing.

02 — Claim Your HST Rebate

You have 2 years from completion to claim. Use the calculator above, then contact HST Rebate Pros.

03 — Budget 15% Contingency

Custom builds almost always encounter unforeseen costs. Build a 10–15% contingency into your budget from day one.

04 — Understand Your Contract

Fixed-price contracts offer budget certainty. Cost-plus contracts can lead to surprises. Know the difference before signing.

05 — Inspect at Every Phase

Schedule independent inspections at foundation, framing, and pre-drywall stages. Problems are cheapest to fix early.
