Custom Home Timeline in Toronto (2026): Lot to Move-In by Phase

From the week you start looking seriously at a lot to the day you get the keys, a Toronto custom home moves through roughly ten phases, and only about half of them involve construction. Surveys, zoning, variances and permits set the pace as much as concrete and framing do. Here's each phase with realistic 2026 durations, what pushes it longer, and how we keep a build moving.

Quick answer: Plan on roughly 12 to 24 months from lot due diligence to move-in for a Toronto custom home. Design and approvals usually need 2 to 6 months between them, a Committee of Adjustment variance typically adds about 3 to 4 months in our planning when one is needed, and construction runs 5 to 14 months depending on size, complexity and finish level. A modest design on a lot that fits zoning can come in under a year; a ravine lot, a variance and a heavily detailed interior push it toward two years.

Key takeaways

• Approvals decide the start date. No zoning certificate means no complete application in Toronto, and without a complete application there's no review clock running at all.
• A variance adds months, not weeks. Neighbours get at least 10 days' notice of the hearing, and the Planning Act allows 20 days to appeal after the decision.
• Construction is 5 to 14 months. Foundations and framing are fairly predictable; finishes, millwork and late design changes are where schedules stretch.
• Inspections are built into the sequence. Footings, foundations, framing, fire separations, insulation and the finals are each signed off by a City inspector, who generally attends within two business days of being called.
• Handover follows Tarion's process. On an enrolled home, the Pre-Delivery Inspection and Certificate of Completion and Possession come before you move in, and the possession date starts the warranty.

The timeline at a glance

These are typical planning ranges from our own scheduling, not City or Tarion standards, and we confirm them for each lot and design. Phases overlap when they're planned well: tree permits move alongside design, and long-lead windows and millwork are ordered while the foundation is going in.

Phase 1: Lot due diligence (2 to 6 weeks)

Before you commit to a design, you need to know what the lot allows. That starts with a current survey by an Ontario Land Surveyor, which Toronto's zoning review relies on. Zoning sets height, depth, coverage and setbacks, and the governing by-law is usually 569-2013, although some lots are still partly covered by a former municipality's by-law. Trees matter early: any private tree with a trunk of 30 cm or wider (measured 1.4 m up) is protected, as is every City street tree, and the ravine by-law reaches structures and grading near protected natural areas. If the lot backs onto a valley or watercourse, TRCA's Regulated Area Search tells you whether a conservation authority permit is in your future, since Ontario Regulation 41/24 treats constructing a building as development activity. If you're still deciding whether to keep the existing house, our renovate vs rebuild guide walks through that call.

Phase 2: Design, engineering and permits (2 to 6 months)

Design runs from concept through structural engineering, mechanical design, the SB-12 energy compliance summary and a grading plan drawn to Toronto's infill lot grading criteria. The faster you make decisions here, the shorter this phase.

Toronto's zoning check comes first. For a new house, the 2026 Zoning Applicable Law Certificate fee is $644.38, with up to three reviews included. With the certificate issued, the permit drawings enter the house stream and its 10-business-day review target, and under the City's Reliance on Professional Engineer's Seal approach, expanded on July 14, 2025, house designs carrying a professional engineer's seal get an expedited review. Taking down the existing house needs its own demolition application, lodged once the new house application is in, along with the demolition control acknowledgement, tree and infill notice declarations, and a road damage deposit. Our Toronto building permit guide covers this stage step by step.

This is also when the contract is signed. Tarion says builders of new homes in Ontario must be licensed by the Home Construction Regulatory Authority (HCRA), and a contract home has to be enrolled with Tarion before the construction contract is signed. If a contract-home construction contract is terminated before the home is complete, Tarion's financial loss coverage is up to $40,000 for amounts paid beyond the value of the work and materials supplied, and Tarion warns that an owner who takes significant control over construction may lose eligibility. Every ground-up custom home we build is enrolled with Tarion, and our warranty page explains what that covers.

Phase 3: Committee of Adjustment, if needed (about 3 to 4 months)

If the design needs relief from zoning, the variances are judged on four tests, from fitting the Official Plan and the by-law's intent to being genuinely minor. A variance file for a new dwelling of up to three units carries a 2026 fee of $5,011.08. Notice is mailed to nearby owners 10 or more days ahead of the hearing, the written decision is sent within 10 days, and the Planning Act then leaves a 20-day appeal window, with Toronto appeals usually heard by the Toronto Local Appeal Body. Your permit drawings then have to match what was approved. Preparing for a new-build hearing, from the planning rationale to talking with neighbours, is covered in our Committee of Adjustment guide.

Phase 4: Demolition and site setup (1 to 3 weeks)

Gas, hydro, water and sewer are disconnected and capped before the machine arrives. Toronto's Residential Infill Public Notice must go up no later than 5 business days before demolition begins. Tree protection goes up before any equipment moves, and the bins, fencing and site access are set. Noise rules shape the working day as well: Toronto bars construction noise from 7 p.m. to 7 a.m. on weekdays, limits Saturdays to the hours between 9 a.m. and 7 p.m., and allows none at all on Sundays or statutory holidays.

Phase 5: Excavation and foundation (3 to 8 weeks)

Excavation is where Toronto's tight lots show. Where the dig comes close to a neighbour's foundation, engineered shoring sets the pace. The footing inspection happens at completion of formwork and before concrete is poured, the sewers and water service are inspected before backfilling, and the foundation is inspected at completion. Groundwater and winter conditions are the variables here; concrete poured in January needs heat and protection, which adds time and cost.

Phase 6: Framing and roof (4 to 10 weeks)

Floors, walls, steel and roof go up quickly on a simple box and slowly on a house with steel moment frames, vaulted ceilings or a complex roofline. Windows should already be on order by now; they're among the longest lead items on a custom home, and the house can't be closed in without them.

Phase 7: Rough-ins (3 to 8 weeks)

Plumbing, HVAC, electrical and low-voltage wiring go in together and have to be coordinated around beams and joists. Toronto's structural framing inspection includes the plumbing and HVAC rough-in, and electrical work runs on its own ESA notification. Founding partner Fred Shik leads the mechanical side of our builds, so ductwork and drains are designed around the structure instead of being forced through it.

Phase 8: Inspections, insulation and drywall (3 to 6 weeks)

Fire separations are inspected before interior finishes, and insulation and vapour barrier before drywall. Covering work before it passes means tearing it open again, so we call for these the moment each stage is ready, and Toronto's inspectors attend within two business days of a request.

Phase 9: Finishes (2 to 5 months)

This is the phase owners underestimate. Custom millwork, stone, tile, stairs, flooring, interior doors, plumbing fixtures, exterior cladding, landscaping and final grading all land here, and each has its own lead time. Custom cabinetry alone can take several weeks to fabricate, so we confirm each supplier's lead time when the order is placed. A Lot Grading Certificate from the grading consultant follows final grades.

Phase 10: Finals, Pre-Delivery Inspection and handover (1 to 4 weeks)

Final interior and exterior inspections close the permit. On a Tarion-enrolled home, the builder then walks you through the house at the Pre-Delivery Inspection, explaining how the systems work and recording anything incomplete or damaged on the PDI Form, which you or a designate sign. The Certificate of Completion and Possession records the possession date, and that date starts the statutory warranty clock. The one-year coverage deals with workmanship, materials and Building Code compliance; the two-year coverage adds water coming through the basement or foundation walls and defects in the electrical, plumbing and heating distribution systems; and major structural defects stay covered for seven years.

What slows Toronto builds

• Approvals that start late. An unissued zoning certificate, a variance appeal or a pending TRCA permit stops everything downstream.
• Design changes after permit. Revised drawings mean revised reviews, and a change made on site rarely stays small.
• Late long-lead orders. Windows, custom millwork and specialty steel ordered after framing will hold up the house.
• Failed or missed inspections. A re-inspection costs days, and covered work that has to be opened costs more.
• Winter and site constraints. Cold-weather concrete, tight access and neighbour shoring all add time on infill lots.

How we keep a custom home on schedule

Our approach is to make the slow decisions early. Layouts, structure and long-lead selections are locked before the permit is issued, windows and millwork are ordered at permit stage, and the build is priced as a fixed contract and run by one accountable team. Founding partner Kash Varjavandi manages timelines and trade coordination, David Bocharov runs the complex builds, and clients follow the live schedule, site photos, selections and change orders in Buildertrend.

FAQ

How long does it take to build a custom home in Toronto?

Plan on roughly 12 to 24 months from lot due diligence to move-in: 2 to 6 months for design and permits, about 3 to 4 more if a variance is needed, and 5 to 14 months of construction depending on size and complexity.

How long does a building permit for a new house take in Toronto?

The house stream's review target is 10 business days, but the clock starts only after the zoning certificate is issued and the file is complete. For a new house, the zoning certificate plus one round of examiner comments usually means two to three and a half months at the permit stage in our planning, so we start ordering long-lead items in that window.

Does a Committee of Adjustment hearing delay a custom home?

Yes, typically by about 3 to 4 months in our planning, though hearing dates vary. Notice, the hearing, the written decision and the 20-day appeal period all have to run before permit drawings can be finalized.

Is a custom home on my own lot covered by Tarion?

A home built under contract on land you own is a contract home, and Tarion requires the builder to enrol it before the construction contract is signed. The statutory warranty runs one, two and seven years from possession for different categories of defect.

Can construction start before the building permit is issued?

No. Section 8 of Ontario's Building Code Act bars construction or demolition until the chief building official has issued a permit, and in Toronto even the demolition application for the old house waits until the new house application has been filed.

What's the slowest part of building a custom home?

Usually the finishes and the decisions behind them. Foundations and framing follow a predictable sequence, while custom millwork, stone and late selections are where months slip.
