Home Additions in Burlington
Burlington’s established neighbourhoods include bungalows, side-splits and detached homes in areas such as Aldershot, Roseland, Shoreacres, Mountainside and Brant Hills, alongside later communities including Millcroft and The Orchard. Depending on the property, additional space may come from building upward, extending the main floor or adding above an existing garage. We assess the home, lot and municipal requirements first so the addition is planned around what the property can realistically support.
BURLINGTON HOMES & ADDITION FEASIBILITY
Planning an Addition Around the Property
Burlington properties can offer more room to work with than denser urban lots, but available yard space alone does not determine what can be built. The existing house, setbacks, building height, lot coverage, grading, mature trees and surrounding property conditions can all influence the size and placement of an addition.
For a bungalow or lower-profile home, a second-storey addition can create significant new living space while preserving the existing footprint. Where the goal is a larger kitchen, family room or more connected main floor, extending to the rear may provide a better fit. Homes with attached garages may also present an opportunity for living space above, provided the existing structure and zoning support it.
The relationship between the addition and the existing layout matters just as much as the amount of new square footage. Stair locations, floor elevations, circulation and natural light need to be considered early so the new space functions as part of the home rather than creating an awkward transition between old and new.
STRUCTURE, FOUNDATIONS & SITE CONDITIONS
Building on What Is Already There
Before adding another level or extending the footprint, the existing home needs to be understood structurally.
A second-storey addition introduces loads that were not part of the original house design. We assess how those loads can travel through the existing walls and framing to the foundations and identify where reinforcement, beams, posts or additional support may be required.
Rear and side additions typically involve new foundations and connections to the original building. Where a larger opening is created between the existing house and the new addition, the structure above needs to remain properly supported while the wall is altered and the new framing is introduced.
Burlington projects can also involve site considerations beyond the house itself. Grading and drainage need to work with the new footprint so water continues to move appropriately around the property, while existing trees may influence where construction can occur. These conditions are addressed as part of the design rather than being left until the permit or construction stage.
PERMITTING & LOCAL PROCESS
Home Addition Approvals in Burlington
Burlington uses a Pre-Building Approval process for residential additions. Before the building-permit stage, the City reviews applicable zoning requirements and can coordinate grading and drainage and forestry requirements through the same process. Large and small building additions, including second-storey additions, are specifically identified by the City as projects requiring Pre-Building Approval.
The City notes that Pre-Building Approval can currently take up to approximately 4–6 weeks, depending on application volumes and whether the submission is complete. Once the necessary approvals are in place and a complete building-permit application is submitted, Burlington states that residential permit plan review is conducted within 10 business days.
Burlington also introduced Residential Zoning By-law 09-2026, which came into force on March 2, 2026. Zoning controls matters such as building size, height, setbacks and where structures can be located on a property. Where a proposal does not comply with the applicable zoning provisions, a Committee of Adjustment application may be required.
Some properties may also require outside-agency review, including Conservation Halton or the Niagara Escarpment Commission, depending on location. We coordinate the design, municipal submissions, review correspondence and required approvals so those requirements are identified before they interfere with construction.
