Complete Home Transformation — Design to Finish

A full-home renovation in Toronto and across the GTA is the single largest investment most homeowners will make outside of buying the house itself, and in 2026 it is also one of the most heavily regulated. Whether you own a 1920s Annex semi being brought into the modern era, a 1960s North York bungalow getting a second-storey addition, or a brand-new Vaughan build that needs a custom layout, the work involves coordinating six to twelve sub-trades, navigating Toronto Chapter 363 building permits, satisfying Ontario Building Code Part 9 (housing) compliance, and managing a budget that almost always falls between $150,000 for a clean 2,000-square-foot basic gut-and-finish and $800,000 or more for premium luxury work with structural changes and additions.

At RenoHouse we run full-home renovations as a single accountable general-contractor engagement, which means one written scope, one stamped schedule, one weekly billing cycle, and one project manager who owns the result from demolition to municipal final inspection. That single-point accountability is the difference between a renovation that finishes in 90 days and one that drags into year two — a story almost every Toronto homeowner has heard from a friend or neighbour. Our typical mid-range gut renovation lands at approximately $350,000 for a 2,000 to 2,800 square-foot detached home, with the structural cost driven primarily by the size of the home, the finish tier, and whether load-bearing walls are coming out or going in.

The compliance side of a Toronto full-home renovation has tightened considerably since 2024. Any project that crosses $150,000 in declared construction value or touches structural framing now triggers Section 11 review at Toronto Building. Engineered drawings sealed by a registered professional engineer (P.Eng.) are mandatory for beam replacements, dropped ceilings hiding new mechanicals, and any wall that supports a roof or upper floor. The Electrical Safety Authority requires a Notification of Work when more than 50 percent of the home is being rewired, and the work must be supervised by a 309A Master Electrician holding an active Electrical Contractor Registration Agency licence. Plumbing is regulated by Skilled Trades Ontario under the 306A plumber trade, and gas work — whether you're moving a furnace, replumbing a hot-water tank, or relocating a gas range — falls under TSSA G1/G2 gas-fitter authority.

What a full-home renovation actually includes

A full-home renovation at RenoHouse means we strip the home back to its useful bones, redesign the interior, and rebuild it to current code with the finishes and layouts the family will live with for the next twenty years. The scope routinely includes selective demolition (with MOL Reg 278/05 DSS asbestos survey on any home built before 1990), complete replumbing of the supply and drain stack, full rewire to 200-amp service with AFCI/GFCI protection where the code requires it, replacement of the HVAC system with a properly sized high-efficiency furnace and central AC or modern heat-pump configuration, new insulation to R-60 attic and R-22 walls, all new windows and doors, complete drywall and trim, new kitchen and bathrooms, hardwood or engineered hardwood flooring throughout, and a freshly painted envelope inside and out.

On the structural side, removing a load-bearing wall to open up a main floor is one of the most common scopes, and it almost always requires an engineered LVL or steel beam header, temporary shoring during the cut, and a P.Eng. review at the design stage. Where homeowners want a second-storey addition, a rear extension, or a basement underpinning to gain head height, the scope grows to include footings, foundation work, framing, roofing, and exterior cladding — all of which add timeline and cost.

Toronto permits, OBC compliance, and the inspection schedule

Toronto Chapter 363 is the bylaw that governs building permits in the city. The application package for a typical full-home renovation runs to a dozen drawings (architectural, structural, mechanical, electrical, site plan), and the review timeline at Toronto Building is typically four to twelve weeks from submission to issuance depending on the volume and whether zoning variances are required. Homes in Heritage Conservation Districts (Cabbagetown, Riverdale, parts of the Annex, Yorkville, and Rosedale, among others) add a Heritage Permit review under Section 41/42 of the Ontario Heritage Act, which extends the timeline by another eight to sixteen weeks.

Mid-project there are mandatory inspections at the framing, insulation, drywall, and final stages, plus separate ESA inspections at electrical rough-in and final, and TSSA inspections at gas connection. Our project managers schedule inspections directly with the municipal inspector calendar and stage the work so trades aren't waiting on sign-offs. Skip an inspection and the city can issue a stop-work order that can pause the project for weeks — we have never had one.

Cost factors, rebates, and what drives your final number

The biggest cost drivers on a Toronto full-home renovation are home size (a 1,500-square-foot bungalow lands very differently from a 4,000-square-foot Forest Hill rebuild), finish tier (cosmetic versus mid-range versus premium luxury), structural changes, the depth of mechanical replacement, and the permit complexity. Premium millwork, stone counters, designer lighting, custom cabinetry, and imported tile can easily double the cost of finishes alone. Phasing the renovation across two years often saves nothing — soft costs and mobilisation fees apply twice.

On the rebate side, RenoHouse helps homeowners stack the Canada Greener Homes Loan (up to $40,000 interest-free for envelope and mechanical upgrades), Enbridge Home Efficiency Rebate Plus for insulation and air sealing, Save on Energy rebates for heat-pump and EV-charger work, and the Multigenerational Home Renovation Tax Credit ($7,500 refundable, 15% of up to $50,000) where the project creates a secondary suite for an eligible relative.

Toronto/GTA neighborhood considerations

• Forest Hill / Rosedale / Lawrence Park (heritage 1910-1930s): Heritage Conservation District review under Ontario Heritage Act Part V on every exterior change — slate roof matching, brick lime-mortar repointing, original wood-sash window restoration. Plaster lath walls require selective demo + lead-paint Reg 90/2024 lead-safe certified scope. Typical full-home scope $850K-$2.4M with 18-26 month timeline. Designated Substance Survey (Reg 278/05) mandatory before any drywall opening — vermiculite, asbestos plaster, lead-paint test panel required.
• North York / Scarborough / Etobicoke (post-war 1950s-1970s): Concrete-block + brick veneer + plaster wall assemblies. Asbestos textured ceiling, vermiculite attic, kraft-paper batt walls, knob-and-tube in some 1950s stock — every renovation triggers a Reg 278/05 DSS sample. Original electrical 60-100 amp panels need upgrade to 200A. Lead-galvanized water service pre-1955. Typical full-home scope $480K-$880K.
• Mississauga / Brampton / Vaughan (1990s-2010s subdivisions): Stock framing, 200A panel, copper water service, ABS drain, R-22 walls already to spec — clean teardown-to-studs scope. No DSS required. Heritage and design-review absent. Typical full-home scope $380K-$680K with 8-14 month timeline. Trade-base for high-volume work.
