Custom Home Builders in North York
Ground-up builds designed around the way you live.
On many North York streets, the original 1950s bungalow uses only part of what its lot is zoned for, so custom home builders in North York spend as much effort on demolition, tree protection and zoning as on construction. A knockdown rebuild resets the foundation, basement height and every system at once, and lets the new house use the full zoning envelope.
Construction for a ground-up home runs about $350 to $650 per square foot, which puts a 3,000 sq ft replacement house at roughly $1.05M to $1.95M to build, with the lot, design fees and soft costs on top. Design and permits usually take two to six months, construction five to 14, and every ground-up home we build is enrolled in Tarion. See the North York area guide or our Willowdale custom homes page.

Knockdown-Rebuild Economics on a North York Lot
The rebuild decision is a cost-per-usable-square-foot question. Gutting the bungalow at $200 to $450 per square foot still leaves you with its 1950s footprint and a low basement, while $350 to $650 per square foot buys a new house that can be taller, deeper and better insulated, with a full-height basement from the start. On a wide North York lot, the extra floor area within the RD zone's height and depth limits often changes the math. See our custom home cost guide, renovate vs rebuild guide and full home renovation in North York.
Demolition, Services and Tree Protection for a North York Rebuild
Toronto ties the residential demolition permit to the replacement house: you apply after submitting the new-house permit, with a survey, a damage deposit for the curb, sidewalk and road, an Owner's Acknowledgement of Demolition Control Conditions and a Tree Declaration Form. A Residential Infill Public Notice must be posted at least five business days before demolition, and before machines arrive we coordinate the disconnection of water, sewer, gas, electrical and communication services with each utility.
Trees often decide the footprint. Private trees 30 cm or more in diameter, all City street trees and every tree in a protected ravine area need a permit to injure or remove, and removal permits require replacement planting, or cash-in-lieu of $583 per tree where there is no room. On valley lots, TRCA treats replacing a home as development activity that needs its own permit.
Tarion and How We Build in North York
When you own the lot and hire us to build, the house is a contract home under Tarion's program, and the builder must enrol it before signing the construction contract. Builders of contract homes must be licensed by the Home Construction Regulatory Authority as both builder and vendor, and warranty coverage is divided into one-, two- and seven-year periods; an owner-built home has no statutory warranty. We coordinate with your architect from feasibility, carry a fixed price through construction, track every selection and change order in Buildertrend, and book City inspections at each stage. Our warranty page and custom home timeline explain what follows.

Common questions
Will a North York knockdown rebuild need a Committee of Adjustment hearing?+
Only if the new design exceeds your lot's zoning. Some owners design within the RD envelope and avoid a hearing; others seek modest variances, such as extra height or coverage. The North York panel's 2026 fee for a new residential dwelling of three units or less is $5,011.08, and a hearing adds months to the permit phase.
Can I demolish my North York house before the new-house permit is ready?+
Not in the usual sequence. Under Toronto's demolition control, the replacement house goes in for its permit first, and the demolition application follows with the owner's signed acknowledgement of the conditions. We time demolition close to permit issuance, so the lot does not sit empty and exposed while drawings are under review.
Is a custom home on land I already own in North York covered by Tarion?+
Yes, when a licensed builder builds it under a construction contract. Tarion calls this a contract home, and the builder must enrol it before the contract is signed. Tarion cautions that if the owner exercises significant control over construction or personally completes parts of the home, it may not be eligible for warranty coverage.
