Ask ten builders what it costs to build a custom home in Burlington and you will get ten confident numbers, most of them a single dollar-per-square-foot figure with no source attached. That number is the least useful thing you can budget from. A custom home is not one cost. It is a stack of four separate costs that each behave differently, and construction is only one layer of it.
Once you see the stack, the wide ranges you find online stop being confusing and start being useful. So that is how we will read it here: layer by layer, with the actual Burlington and Halton figures, and a source you can check for each one.
The cost isn’t one number, it’s a stack of four
Break “cost to build” into the parts that move independently and you get four layers:
- Land. The lot you build on, which varies more by neighbourhood than anything else on this list.
- Hard construction costs. Everything physical: excavation, foundation, framing, mechanicals, finishes. This is the layer people mean when they say “cost per square foot.”
- Government and soft costs. Development charges, the building permit, Tarion enrolment, design, engineering, surveys, and financing. Much of this is fixed by rate schedules, not by your taste in kitchens.
- Contingency. The money you hold back for what the first three layers didn’t predict.
The reason a single per-square-foot quote misleads you is that it only ever describes layer two, and only loosely. The other three layers are real money, and on a Burlington build the government portion alone regularly runs into six figures before a stud is framed.
Hard construction: a wide range, and what moves you through it
There is no Burlington-only cost-per-square-foot figure published by anyone credible, so the honest source is regional. Altus Group’s 2025 Canadian Cost Guide puts GTA private-sector hard construction for a standard single-family home with an unfinished basement at roughly $200 to $275 per square foot, and for a custom-built single-family home at roughly $520 to $1,130 per square foot (GTA-wide, as at January 31, 2025). Those are GTA figures, not Burlington-specific, and the spread inside them is the whole point: the low end is a builder-grade box, the high end is a heavily customized home.
What moves you through that range is concrete, not mysterious:
- Above-grade versus below-grade area. A finished basement and a walk-out change the per-foot math.
- Foundation and site conditions. Slope, soil, servicing, and whether you are rebuilding on an existing lot all move excavation and foundation cost.
- Design complexity. Simple rectangles are cheaper to frame and roof than articulated ones.
- Finish level. This is the single largest swing, and the one most under your control.
Costs are also a moving target. Statistics Canada’s building construction price index showed national residential construction costs up about 3.0% year over year as of Q4 2025 (released January 27, 2026). Direction is not uniform, though. Altus has since noted that Toronto-area costs stabilized and softened slightly through 2025 on slower development activity. The takeaway is not a number to bank on; it is that any per-foot figure you read has a shelf life, so confirm current pricing before you build a budget around it.
The Burlington fee floor: what you owe before a stud goes up
Here is the layer competitor calculators skip entirely, and it is the one you cannot finish-level your way out of. These charges are set by government schedules and apply regardless of how modest your finishes are.
Every figure below is current as of July 2026. Development charges re-index every April 1, so the numbers here come from the City’s schedule reissued for that index. Burlington’s building permit fee schedule was also reissued this year under a new by-law. Tarion’s schedule changes on its own cycle. Treat these as the shape of the bill, not a quote, and confirm current rates with the City of Burlington, the Region of Halton, and Tarion before you budget.
| Charge | Who sets it | 2026 figure, single detached |
|---|---|---|
| Municipal development charge | City of Burlington | $22,474.00 |
| Regional development charge | Region of Halton | $54,695.43 (built boundary) to $79,880.67 (greenfield) |
| Education development charge | Halton school boards | $12,021.25 ($7,052.25 public plus $4,969.00 Catholic) |
| Building permit fee | City of Burlington | formula-based, see below |
| New home enrolment | Tarion | $585 to $6,055 by sale price |
The City of Burlington’s development charge schedule (effective June 1, 2026, reflecting the April 1, 2026 index) is where the first three lines come from. Add the development-charge lines together and you land at roughly $89,000 on a built-boundary lot and north of $114,000 on greenfield land for a single or semi-detached home, on 2026 rates. Two things to be clear about: the City does not publish that combined total as one line, it is simply the sum of three separately published charges, and the number changes every April 1 when the rates re-index.
The building permit fee is its own calculation, and here the widely reported “proposed” increase did not end up moving the number. Burlington’s Building Department floated a 5.35% fee increase for 2026, but the schedule actually in force now, Schedule A to By-law 30-2026 (passed May 26, 2026, replacing the old building by-law), lists the same rates as the 2025 schedule it replaced: $23.18 per square metre up to 300 square metres of floor area, or $29.90 per square metre over that, with a $377 minimum. A roughly 325-square-metre home (about 3,500 square feet) sits in the higher bracket, which works out to somewhere around $9,700 in permit fees alone. Rates can still change again on a future cycle, so check the schedule in force when you apply rather than assuming this number holds indefinitely.
Tarion enrolment is the last piece of the floor. Tarion’s enrolment fee schedule is tiered by sale price, from $585 on homes at or below $300,000 up to $6,055 on homes over $4 million (effective September 1, 2025). If a licensed builder or vendor builds your home under contract, which is what a contracted custom build is, enrolment is required. The fee is normally folded into the home’s price rather than billed to you separately.
Put the floor together and, before you have chosen a single fixture, a Burlington custom build carries roughly $89,000 to $114,000 in development charges, on the order of $9,000 to $10,000 in permit fees on a mid-size home, and up to a few thousand dollars in Tarion enrolment. That is the part of the budget that does not care how tasteful you are.
Land, design, and the money you set aside for surprises
Two layers of the stack resist a clean number, and it is more honest to say so than to invent one.
Land is the largest single variable and the one nobody can put a reliable range on. Burlington lot prices swing enormously by neighbourhood, by whether you are buying a teardown or raw land, and by frontage and depth. There is no published aggregate worth quoting. Work from actual comparable listings for the streets you are considering, not a rule of thumb.
Soft costs are the professional services that make the build legal and buildable: architectural or design work, structural engineering, surveys, and financing, typically a construction loan drawn in stages. These are real line items, not rounding error, and they show up early in the schedule, before construction cash starts flowing.
Contingency is the layer people cut first and regret most. Site conditions, scope changes, and material lead times all produce costs the original estimate could not see. There is no single “correct” percentage, but many builders and lenders recommend holding a contingency so that a surprise is a line item rather than a crisis. On financing, taxes, and warranty specifics, talk to a mortgage broker, an accountant, and a licensed builder rather than treating any online figure as settled.
If a full teardown-rebuild turns out to be more than the project needs, the same cost logic applies to a deep renovation, where the timeline and where budgets slip follow a similar pattern. And if your real need is smaller-scale, the arithmetic on an ADU is different again.
How to turn this into a real number for your lot
You cannot get an honest total from a blog post, ours included, and any builder who hands you one before seeing your property is guessing. What you can do is show up informed. You now know the four layers, roughly what the Burlington fee floor costs on the rate schedules in force in 2026, and which numbers move with your choices versus which are fixed by a rate schedule.
The next step is a site-specific read: the lot, the design intent, the finish level, and the actual current charges, priced as one scoped estimate rather than a per-foot headline. That is how we approach custom home builds in Burlington, and it is the only way the ranges above resolve into a number you can plan around.
Before you get that far, What to Ask Before Hiring a Custom Home Builder is the right next read, so that when a builder does put a number in front of you, you know what it should include and what to push on. When you are ready to price your specific lot, start a conversation and we will walk it with you.
