Cost to Build a Custom Home in Burlington and Oakville: 2026 Guide
Updated October 13, 2026
The cost to build a custom home in Burlington and Oakville comes down to two numbers: what the house costs per square foot, and what the lot brings with it. Both matter. In Halton, the lot alone can swing the total by six figures.
Direct Answer: Custom homes in the GTA run about $520 to $1,130 per square foot to build, before land [1]. On a vacant lot, Halton, city or town, and school board development charges can pass $100,000 [2]. A teardown that replaces one house with one house can cancel most of those charges if permits are timed right.
TL;DR
A custom home's per square foot rate is only half the budget. In Halton, the lot can move the total by six figures.
A like-for-like teardown gets credits against Halton Region and city or town development charges if the new building permit comes within 5 years of the demolition permit.
The school boards exempt a replacement home only if the permit comes within 2 years of demolition.
Most development charges are now paid at occupancy, but school board charges and Halton's Recovery Payment are due before the permit.
Oakville pairs the demolition and building permits and can lien $20,000 per unit if the new house isn't built and occupied within 2 years.
Tree permits, drainage rules and Conservation Halton approvals add lot-specific costs in both cities.
Price the lot before the house, and time the permits so the credits hold.
Teardown or Vacant Lot: Why the Lot Moves the Total More Than the Rate
In short: A teardown that replaces one house with one house usually pays far less in development charges than a vacant lot, as long as the new building permit comes through on time.
When you demolish a house in Burlington or Oakville and build one new house in its place, Halton Region, the city or town, and both school boards credit or exempt the unit you took down [3][4][5][6]. A vacant lot gets no credit, so it pays every charge in full.
The catch is timing. Each credit runs on a clock that starts the day the demolition permit is issued.
Charge | What a like-for-like teardown gets | New building permit must be issued |
|---|---|---|
Halton Region development charges | Credit for the house demolished | Within 5 years of the demolition permit [3] |
City of Burlington development charges | Credit for the house demolished | Within 5 years of the demolition permit [4] |
Town of Oakville development charges | Credit for the house demolished | Within 5 years of the demolition permit [5] |
School board education charges (HDSB and HCDSB) | Exemption for a replacement home on the same site | Within 2 years of the demolition permit [6] |
The two-year school board window is the one to watch. If design and drawings run long and the building permit lands after it, the boards are no longer required to exempt you, and their charges come back.
A few details change the math. If you need to live in the old house while the new one goes up, the Region and Burlington have you pay the full charge for the new house. They refund the credit if the old house comes down within 12 months of the new building permit [3][4]. A credit can cancel a charge, but it never pays out more than that charge. And the Region's $9,500 Front-ending Recovery Payment sits under a separate agreement, not the development charge by-law, so confirm with Halton's Development Officer whether your lot owes it [7].
Keeping the permit inside both windows is a scheduling job. Design, engineering and permit drawings need to be ready before the demolition permit starts the clock. That sequencing is a core part of what a custom home builder in Oakville or Burlington manages on a teardown. If the existing house might be worth keeping, weigh renovating against building new before you pay for demolition.
Custom Home Cost Per Square Foot: Burlington and Oakville Ranges
In short: Custom builds sit well above production-home rates, and finishes and design decide where in the range you land.
Neither city publishes its own build-cost figure. The closest neutral benchmark is Altus Group's construction cost data for the Greater Toronto Area [1][8]. Use it as the starting point for the custom home cost Oakville and Burlington families are budgeting, then add the lot costs covered in the sections below.
Build type | Cost per sq ft | 3,000 sq ft house | Source |
|---|---|---|---|
Production-quality single-family, GTA | $150 to $275 | $450,000 to $825,000 | Altus Group 2026 [8] |
Custom-built single-family, GTA | $520 to $1,130 | About $1.56M to $3.39M | Altus Group, reported December 2025 [1] |
Both ranges exclude land. The production figure assumes an unfinished basement. Altus tracks hard construction costs, so development charges, permits and site work sit on top.
On the same 3,000 square foot plan, moving from the bottom of the custom range to its midpoint adds about $915,000. Four things decide where you land:
Size. A kitchen, bathrooms and the mechanical system don't scale down with the floor plan, so the per square foot figure climbs as the house gets smaller [9].
Finish level. Stone, millwork, windows and appliances.
Complexity. Steep or broken rooflines, wide openings and steel beams add engineering and labour.
The basement. A finished basement adds its own cost on top of the above-grade figure.
A custom home builder in Burlington can price your plan against these bands before the drawings are final.
Halton Development Charges on a New Home: Who Charges What, and When
In short: A new single-detached home in Burlington or Oakville pays four layers of charges, and most of the money is now due at occupancy rather than at permit.
Halton Region, your city or town, and the two Halton school boards each charge a new home. On urban lots, Halton also collects a separate Front-ending Recovery Payment, with some exceptions. Your water and wastewater rate depends on whether the lot sits in Halton's Built Boundary or its Greenfield area, and Halton confirms that for each address [7].
Layer | Single-detached amount | When it's paid |
|---|---|---|
Halton Region, roads and general services | $41,368.50 [7] | Before first occupancy |
Halton Region, water and wastewater | $38,512.17 in Greenfield areas; lower in the Built Boundary [7] | Before first occupancy |
Halton Front-ending Recovery Payment | $9,500 where it applies [7] | At building permit |
School boards (HDSB and HCDSB combined) | $12,021.25 [5] | Before the building permit is issued |
City of Burlington | $20,595 base rate in By-law 41-2024, indexed each April [4] | At occupancy [10] |
Town of Oakville | Set by the Town's current rate schedule [5] | At occupancy [5] |
Halton Region rates apply April 1, 2026 to March 31, 2027. School board rates are as of June 1, 2026.
The timing matters for cash flow. The school board charges and the Recovery Payment, about $21,500 together, are due before the building permit is issued [5][7]. The Region, city and town charges on a home you'll live in now wait until occupancy, after recent changes to the Development Charges Act [7][10]. That moves the largest share of the bill to the end of the build instead of the start.
Every layer re-indexes each year: the Region, Burlington and Oakville on April 1, and the school boards on June 1 [4][5][7]. Burlington council also voted in June 2026 to apply to a provincial and federal program that would cut residential charges by 30 to 50 percent for three years if approved. Oakville is not applying [5][11]. Confirm the rate in effect on the day your permit is issued.
Teardown and Rebuild Cost: Oakville and Burlington Line Items
In short: A teardown adds demolition, a handful of Halton servicing fees and, in Oakville, a firm deadline to finish the new house.
Beyond the build itself, these are the lines a teardown carries that a vacant lot usually doesn't.
Teardown line | Cost | Source |
|---|---|---|
Demolition of the existing house | $10,000 to $45,000, with asbestos pushing it toward the top | NerdWallet Canada [8] |
Halton residential water permit application | $238 | Halton Region 2026 fees [12] |
Water main tap (20 to 50 mm) | $496.96 | Halton Region 2026 fees [12] |
Water service inspection, public side (20 or 25 mm) | $536 | Halton Region 2026 fees [12] |
Inspection of the old service disconnection | $356 | Halton Region 2026 fees [12] |
Water meter installation | $409.44 (20 mm) or $515.03 (25 mm) | Halton Region 2026 fees [12] |
Halton fees are 2026 rates. Halton can waive connection fees when the existing water service is large enough and sound [12]. Your contractor's excavation and pipe work is extra.
Oakville adds a deadline. Under its demolition control by-law, the Town won't issue a demolition permit until the permit for the new house is ready to issue [14]. Demolition then has to be finished within six months, and the new house built and occupied within two years after that. Miss it, and the Town can add $20,000 for each demolished unit to the tax roll, where it becomes a lien on the property [13].
Because the two permits issue together in Oakville, the school boards' two-year window from earlier is easy to meet there. The bigger risk is a build that runs long. In Burlington, the credit windows covered earlier are the dates to manage, along with your local utility clearances before demolition starts. Oakville, for example, lists an Oakville Hydro clearance among its pre-permit requirements [14].
Tree Permits and Replacement Costs in Burlington and Oakville
In short: Both cities charge to remove a protected tree and make you replace it. Oakville protects smaller trees, charges more on construction projects and expects the replacements on your own lot.
Mature trees are a big part of the appeal of an older Halton lot, and they come with rules. Both cities measure trees by diameter at breast height (DBH), taken 1.37 metres above the ground [15][16].
Burlington | Oakville | |
|---|---|---|
Permit needed from | 20 cm DBH, inside the urban area | 15 cm DBH |
Permit fees | $54 application, plus $351.50 for 1 to 3 trees, $243.50 for the 4th and $135.50 for each after | $900 per tree on a construction project (a first tree of 15 to 24 cm is $65) |
Replacement trees | 2, 3 or 4 per tree removed, by size | 1 for every 10 cm DBH removed |
Cash-in-lieu | $257.50 per replacement tree | Only if there's no room to replant on the lot |
Refundable security when replanting | $257.50 per replacement tree | $300 per replacement tree |
Fees as published in 2026. Burlington fees are plus HST [15][16].
Take one healthy 40 cm tree that has to come out for the new house.
Burlington: $405.50 in fees plus HST, then either three replacement trees backed by a $772.50 refundable security, or $772.50 cash-in-lieu.
Oakville: $900 in fees, plus four replacement trees backed by $1,200 in refundable security [15][16].
Trees you keep can cost money too. In Burlington, any work inside a tree's protection zone counts as injury and needs its own permit at $81.50 plus HST per tree [15]. Plan the footprint, driveway and servicing route around the trees from the first sketch.
How Lot Conditions Change the Total
In short: Three lot features add approvals and engineering before construction starts: regulated land near water, drainage, and how the lot is serviced.
Two lots at the same asking price can carry soft costs that differ widely. Check these before you firm up an offer.
Lot condition | What it triggers | Cost or time signal |
|---|---|---|
Near a creek valley, wetland or the Lake Ontario shoreline | A Conservation Halton permit under Ontario Regulation 41/24 [17] | Up to 90 days for a permit decision; $360 for a formal letter confirming whether the property is regulated [17][18] |
Any new house in Burlington | A Grading and Drainage Clearance Certificate before the building permit [19] | A plan stamped by an engineer or surveyor, plus a city fee and security |
More hard surface than Burlington allows (50, 55 or 60% of the lot, depending on frontage) | Drainage review [19] | Split-drainage lots may need drainage works sized for a 100-year storm |
Rural lot not connected to municipal water or sewer | No Regional water or wastewater charges [7] | A private well and septic system instead |
Designated heritage property, or inside a Heritage Conservation District such as Old Oakville or Burlington's Burlington Avenue and Ontario Street district, adopted in 2026 | A heritage permit before demolition or major exterior work [21][22] | Council can refuse demolition; Oakville reviews applications at monthly Heritage Oakville committee meetings [21] |
The drainage rule is the one buyers miss. If a Burlington lot goes over the hard-surface limit but drains back to front with proper swales, the city doesn't require extra drainage works. If it drains in two directions, it may need them, and the owner pays to prepare and register an agreement for that equipment [19]. Soil is the other unknown, so get a survey and a soil report before you commit to a design.
Sample Budget: The Same House on a Vacant Lot and a Teardown Lot
In short: With the same house and the same plans, a timed teardown in Burlington can come in about $67,000 to $112,000 under a vacant Greenfield lot, before you count what each lot costs to buy.
Line | Vacant lot, Burlington Greenfield area | Teardown lot, permits timed |
|---|---|---|
Construction, 3,000 sq ft at $520 per sq ft [1] | $1,560,000 | $1,560,000 |
Demolition [8] | $0 | $10,000 to $45,000 |
Halton Region development charges [7] | $79,880.67 | $0 (credited) [3] |
Front-ending Recovery Payment [7] | $9,500 | $0 to $9,500 (confirm with Halton) |
School board charges [5] | $12,021.25 | $0 (exempt within 2 years) [6] |
City of Burlington development charge, by-law base [4] | $20,595 | $0 (credited) [4] |
Halton water permit, tap, inspections and meter [12] | $1,785.99 | $2,141.99 |
Total before land, trees and soft costs | About $1,683,800 | About $1,572,100 to $1,616,600 |
Assumptions: the bottom of the GTA custom range, a 25 mm water meter, and a building permit issued within two years of the demolition permit. Burlington's charge is shown at its by-law base rate, so the indexed 2026 figure will be higher. Built Boundary lots pay a lower Regional water and wastewater charge, which narrows the gap. Oakville follows the same structure, with the Town's rate in place of Burlington's.
Land price sits outside this table, so compare it separately. What the table shows is what a teardown's credits are worth, and that the saving only holds when the building permit lands inside the windows.
HST, Rebates and Contingency
In short: Tax, rebates and a contingency line apply to every new home in Ontario, so they sit in your budget on top of the Halton costs above.
New construction in Ontario carries HST. If you hire a builder to put a house on land you already own, including a teardown lot you bought first, you claim the owner-built new housing rebates from the CRA. Ontario has also introduced a temporary enhanced rebate on the provincial part of the HST [20]. Custom builds can take up to two years, and construction mortgages pay out in stages as work is inspected, so budget for loan interest and somewhere to live while the house goes up [8]. For rebate limits, finish-level ranges and contingency planning, see the Ontario custom home cost guide.
Frequently Asked Questions
In short: Quick answers on build costs, development charges, teardowns, trees and rebates.
How much does it cost to build a custom home in Burlington and Oakville?
Construction for a GTA custom home runs about $520 to $1,130 per square foot before land [1]. On top of that, a vacant lot pays Halton, city or town, and school board development charges, while a timed teardown can cancel most of them.
What is a realistic custom home cost per square foot in Burlington?
A realistic custom home cost per square foot in Burlington sits well above the $150 to $275 GTA production-home benchmark [8]. Size, finish level, design complexity and a finished basement all push the figure higher.
Do you pay development charges on a teardown and rebuild in Oakville?
Often little or nothing. Halton Region and the Town of Oakville credit the demolished house if the new building permit is issued within five years of the demolition permit, and the school boards exempt it within two years [3][5][6].
What are Halton development charges on a new home?
Halton development charges on a new home come in four layers: Halton Region, your city or town, the two Halton school boards, and a separate Front-ending Recovery Payment. Regional roads and general services alone are $41,368.50 per single-detached home in 2026 [7].
When are development charges paid in Halton?
For a home you'll live in, Region, city and town charges are now paid before first occupancy. School board charges and the Region's Front-ending Recovery Payment are still due before the building permit is issued [5][7][10].
Do you need a permit to remove trees for a new house in Burlington or Oakville?
Yes, for larger trees. Burlington requires a permit from 20 cm in trunk diameter inside its urban area, and Oakville from 15 cm. Both require replacement trees, and Oakville expects them on your own lot when there's room [15][16].
What does Oakville's demolition control by-law require?
Oakville won't issue a demolition permit until the replacement building permit is ready. Demolition must finish within six months, and the new house must be built and occupied within two years, or the Town can add $20,000 per demolished unit to the tax roll [13][14].
Can you claim an HST rebate on a custom home you build on your own lot?
Yes, if you qualify. The CRA offers owner-built new housing rebates when you build, or hire a builder to build, a home on land you already own. Ontario also has a temporary enhanced rebate on the provincial part of the HST [20].
