Custom Home Builder Burlington

Two by-laws and a commission

Before a custom home builder Burlington owners hire can price anything, someone has to answer a plain question: which rules apply to this lot? In most cities that has one answer. The City of Burlington's own zoning page says there are currently two zoning by-laws in effect, and points a third group of owners somewhere else entirely.

The Burlington Residential Zoning By-law (By-law 09-2026) came into force on March 2, 2026, and covers the city's residential neighbourhoods. Zoning By-law 2020 still covers the non-residential and rural areas, including the rural zones RA, RG and ME. And if a property sits within the area of the Niagara Escarpment Commission, Burlington tells owners to go to the NEC for their zoning information.

So the first hour of any conversation about a new house in Burlington is spent on a map, not a floor plan. Get it wrong and every number that follows, from the height of the roof to the size of the footprint, is checked against the wrong document.

We are DMT Building Group. We are based in Barrie, Ontario, and build south into the Greater Toronto Area. We build custom homes in insulated concrete form (ICF), from the footings to the roofline, with our own crews doing the concrete. What follows is how a new Burlington house gets from that first map question to a hole in the ground.

How tall, and what shape, under the 2026 by-law

Table 8 of the Burlington Residential Zoning By-law sets the envelope for a detached house in the LN1 to LN6 zones. The height limit is the one that changes most by neighbourhood, and it changes in ways a design from another city would not anticipate.

Burlington's by-law draws those areas precisely. Alton is the land between Highway 407, Appleby Line and Dundas Street. Orchard runs from Upper Middle Road up to Dundas Street and the CN line, between Appleby Line and the Bronte Creek valley. The lakeshore allowance applies to lots that front Lakeshore Road or North Shore Boulevard, and to everything south of them.

A few other lines in the same section shape a custom Burlington house more than people expect:

• Garage doors. All garage door openings facing a street may not exceed 50% of the width of that elevation, and an attached garage facing the street may not project past the longest street-facing wall that contains living space.
• Front yard. The minimum front yard can be reduced to the established front yard on the street, as long as the house stays at least 1 m from the street line.
• Soft landscaping. At least 30% of the front yard in LN1 to LN4, 40% in LN5 and 50% in LN6 must stay soft landscaped.
• Coverage. From 50% in LN1 and LN2 down to 35% in LN4 to LN6, rising to 45% on LN3 to LN6 lots that include an additional residential unit.

That last line connects to another change. Section 5.14 permits up to three additional residential units on an urban residential lot. In the LN8 zone, a new detached house is only permitted if it contains at least one attached additional unit. A custom home in Burlington can now be designed from day one with a suite in it, and on some lots the zoning expects one.

If your Burlington drawings were started under the old by-law, Section 1.16 matters too. A building permit application the City had as complete on or before March 2, 2026 can proceed under Zoning By-law 2020. Anything later is checked against the new rules.

Charges, conservation and the lake

Two more bodies have a say on many new Burlington houses. Halton Region levies its own development charges beside the City's. For a single detached house, the Region's page says the rate is fixed at building permit issuance (or earlier, at subdivision approval, for its water, wastewater and roads components), and the charge is collected before first occupancy. The City of Burlington's current development charge rates took effect June 1, 2026, and both governments index their rates every April 1. Get the current numbers from each before you set a budget.

Conservation Halton regulates work in and next to watercourses, floodplains, valley lands, steep slopes, wetlands and the Lake Ontario shoreline under Ontario Regulation 41/24, and the Burlington by-law adds Burlington Bay by name. Section 5.44 keeps every new house at least 6 m from the floodplain, meander belt or stable top of bank of a watercourse unless Conservation Halton permits less. Its legislated limit to issue a Burlington permit is 90 days, and its own page notes that its permission does not replace the City's or the NEC's.

Choosing among custom home builders in Burlington

We will be plain about distance from Burlington. We are not one of the Burlington home builders with an office in town; we are based in Barrie and build across the GTA, and the nearest work in our gallery is the curved ICF walls in Oakville. If you want a firm that designs, sells and finishes the whole house under one roof, compare us with local design-build firms on that basis.

If you are talking to custom home builders Burlington Ontario owners have shortlisted, ask each one two things. Who pours the foundation and raises the walls: their own crew, or a subcontractor? And which by-law have they checked your lot against? A custom home builder in Burlington who has not asked about the March 2026 by-law, the escarpment or the trees on your lot has not looked yet.

Most of our calls come from builders who already know ICF, and we regularly do the concrete and ICF scope under another builder or general contractor. So if you have already chosen one of the custom home builders Burlington offers and want the structure in insulated concrete, we can work under them. The budget side is in what ICF actually costs, and the energy side in ICF vs conventional R-value.
