Expand your square footage with expertly designed and permitted home additions in Etobicoke.
We specialize in matching new additions to the existing architectural fabric of your Etobicoke home. By carefully sourcing matching brickwork, roof tiles, and trim profiles, we ensure the new structure looks like it was always part of the house. This meticulous attention to detail protects your home's curb appeal and significantly increases its resale value.
Our team handles the entire navigation of Etobicoke's building permits and Committee of Adjustment processes. We prepare detailed CAD drawings and engineering reports that meet the specific requirements of the Toronto Building Department. This expertise helps bypass common bureaucratic hurdles and speeds up the start of your construction phase.
Every addition we build in Etobicoke is engineered for maximum energy efficiency to combat local climate shifts. We use premium spray foam insulation and triple-pane windows that exceed Ontario Building Code standards. This ensures your new living or working space remains quiet, comfortable, and cost-effective to heat and cool throughout the year.
We begin by analyzing your Etobicoke property's survey and local zoning bylaws to determine the maximum buildable area. This step is crucial for identifying any constraints like drainage easements or tree protection zones early. By understanding the 'legal' envelope of your lot, we can design a space that is guaranteed to pass municipal review.
Our designers work with you to create a functional floor plan that meets your living or working goals. We produce professional CAD drawings and 3D renderings so you can visualize the addition before construction begins. This stage ensures that every window, door, and electrical outlet is exactly where you need it to be for your lifestyle.
We handle the submission of all structural engineering reports and architectural drawings to the City of Toronto. Navigating the permit office can be frustrating for homeowners, so we act as your primary contact to answer technical questions from inspectors. This ensure that your project starts on a firm legal and structural foundation without unnecessary delays.
Once permits are issued, our site supervisors manage the trades, materials, and inspections daily. We focus on structural integrity—from the foundation pour to the roofing tie-in—ensuring your addition is weather-tight and built to last. You will receive regular updates on progress, so you always know what to expect in the coming week.
A minor variance is required if your proposed addition exceeds the current zoning bylaws for your specific Etobicoke property, such as maximum floor space index (FSI) or minimum setbacks. Our team reviews your property survey against local Toronto bylaws during the consultation phase to determine if a Committee of Adjustment hearing is necessary. We have extensive experience preparing the required documentation and representing homeowners at these hearings to secure the necessary approvals.
Costs vary significantly based on the type of addition—whether it is a 'bump-out' foundation-up build or a second-story addition. In Etobicoke, professional additions generally range from $350 to $500 per square foot depending on the complexity of the structure and the level of interior finishes. This includes everything from initial permits and engineering to final paint and flooring, ensuring there are no hidden costs as the project progresses.
We strive to maintain the functionality of your existing home for as long as possible during the addition process. For rear extensions, we typically build the new structure as a 'pod' and only break through the existing exterior wall in the final stages, minimizing exposure. We provide a detailed project schedule so you can plan for the 2-3 week period when major utility cut-overs or structural tie-ins might temporarily limit access to certain areas of your home.
Yes, we are experts in optimizing space for multi-unit use or secondary suites in Etobicoke. This often involves specific fire-separation requirements, soundproofing, and separate utility meters as mandated by Toronto's building codes. We can design the addition with its own private entrance and kitchenette, allowing you to maximize the rental potential or provide private living space for extended family members.
Transform your property into a high-value asset by navigating Toronto's specific legal requirements for basement apartments and garden suites.

Learn MoreWe hired Built By Pros for a 600-square-foot second-story addition on our Etobicoke bungalow. Ricardo and his team were incredibly professional, finishing the structural framing in less than three weeks despite a heavy February snowstorm. They handled the complex plumbing integration for our new master ensuite perfectly. The communication from Suzanne regarding our finish selections held the whole project together. We finally have the office and master bedroom we've needed for years.
Our rear kitchen extension and family room addition in the Kingsway area exceeded all expectations. Built By Pros managed the delicate work of matching our 1940s brickwork so well that you can't tell where the old house ends and the new one begins. The project was completed within our 5-month timeline, and the site was kept impressively clean for such a large build. Their interior designer, Petra, helped us settle on an open-concept layout that completely transformed how we use our main floor.
After interviewing several contractors for our Etobicoke home office addition, we chose Built By Pros because of their detailed quote and design-build approach. They handled a difficult permit issue with the city regarding our side-yard setback that saved us thousands in potential redesign costs. The quality of the interior woodworking and the glass railing on the new stairs is world-class. It was clear from day one that Bastian and the crew took genuine pride in their craftsmanship.
