A residential general contractor (residential GC) is the single accountable professional who plans, coordinates, and delivers a multi-trade home renovation, addition, or major remodel. Distinct from a specialist trade (plumber, electrician, tile setter) and from a handyman, the residential GC's job is project management: scope definition, design coordination, permit handling, scheduling, trade hire and supervision, quality control, financial management, and homeowner communication. This page covers what to expect from a quality residential GC in Ottawa, 2026 fee structures and pricing, the con...
Choosing the right kind of professional for the job is the first decision, and getting it wrong wastes money in both directions. The residential GC earns their fee on multi-trade complexity, not on simple tasks.
Hire a residential general contractor when a project crosses multiple trades, requires permits and inspections, involves structural change, or carries a budget above roughly fifty thousand dollars. Whole-home renovations, additions, gut kitchens with wall removal, and second-storey builds all demand...
A handyman is ideal for small repairs, mounting, minor carpentry, and odd jobs that need no permit, but is the wrong choice for permitted, structural, or multi-trade work. In Ottawa, electrical work must be done and permitted by an ESA-licensed electrician and gas by a TSSA-registered fitter regardl...
A residential general contractor is the single point of accountability for a whole project: design coordination, permits, materials, every trade, scheduling, inspections, and the final result. A good GC engagement starts with a consultation and budget range, moves into a fixed-scope contract and detailed schedule, then into permitting and procurement before demolition. The GC value is not swinging a hammer; it is orchestration, because the difference between a renovation that finishes on time an...
Most GC-scale projects require a City of Ottawa building permit, applied for through the city online client portal. Removing a load-bearing wall or building an addition needs engineer-stamped structural drawings, and additions need architectural drawings and often a site plan. Electrical work is per...
The GC builds and owns the schedule, sequencing demolition, framing, the rough-in trades, City and ESA inspections, insulation, drywall, and the finishing trades in the correct order. When a material slips or an inspection is delayed, the GC reshuffles the crews so progress continues. Expect a writt...
Residential GC projects in Ottawa span a wide range in 2026: a major room renovation runs 50,000 to 200,000 dollars, a whole-home renovation 200,000 to 750,000, and a large addition or full gut 300,000 and up. A residential GC typically charges either a fixed price or cost-plus with a management fee, usually fifteen to twenty percent for overhead, coordination, and profit. Carry a ten to fifteen percent contingency, because older Ottawa homes routinely reveal hidden conditions once walls and flo...
A fixed-price contract gives budget certainty and is best when the scope is well defined and drawings are complete; the GC carries the risk of estimating errors, so quotes include contingency. Cost-plus, where you pay actual trade and material costs plus a set management fee, suits open-ended or evo...
A professional residential GC works on a written contract with a payment schedule tied to completed milestones, never a large up-front deposit. Under the Ontario Construction Act you are entitled to retain a ten percent holdback against unpaid subtrades and suppliers, releasing it only after the lie...
Before signing, verify the GC credentials, understand the warranty, and time the project to the season that fits the work. Ottawa freeze-thaw climate and varied housing stock shape both scope and scheduling.
Require proof of at least two million dollars in commercial general liability insurance and a current WSIB clearance certificate, verified directly through the WSIB website rather than a forwarded PDF. Confirm that licensed trades, an ESA-licensed electrician, and a TSSA gas fitter handle the regula...
Century homes in the Glebe, Sandy Hill, Westboro, and Old Ottawa South require heritage-aware planning and frequently expose knob-and-tube wiring, plaster, and out-of-level structure, while suburban homes in Barrhaven, Kanata, Orleans, and Riverside South are more predictable to renovate. Interior r...
A residential GC owns the project from contract signing through final inspection. Core responsibilities: (1) Scope definition — turning your wish list into a detailed scope of work with quantities, allowances, exclusions, and assumptions. (2) Design coordination — working with the designer or architect, or providing in-house design service, to produce buildable drawings. (3) Permit application — filing with the City of Ottawa, coordinating ESA electrical permits, plumbing permits, and any herita...
Hire a residential GC when: your project involves 3+ trades, requires a building permit, runs longer than 2 weeks, involves structural work, or has a budget over $40K. Hire trades directly when: project is single-trade (just painting, just flooring, just window replacement), runs under 2 weeks, doesn't require a permit, and you have time and skill to coordinate. The GC's 15-20% management markup pays for itself on multi-trade projects through: better trade pricing (volume relationships), reduced...
A residential GC plans and delivers multi-trade home renovations end-to-end: scope definition, design coordination, permit application, scheduling, trade hire and supervision, material procurement, quality control, financial management, homeowner communication, and inspection coordination. They're the single accountable professional for projects involving 3+ trades or requiring permits.
Management fee is typically 15-20% of total project cost, or $15K-$20K on a $100K renovation. Fixed-price contracts run 5-10% premium over cost-plus because the GC bears all risk. Total project cost for whole-home renovations: $250K-$750K, additions $200K-$750K, kitchen+bath+flooring bundles $80K-$200K.
Hire a GC when: 3+ trades involved, permit required, project longer than 2 weeks, structural work, or budget over $40K. Hire trades directly for single-trade work under 2 weeks. The GC's 15-20% markup pays for itself on multi-trade projects through coordination, scheduling, and accountability.
Fixed-price: GC quotes complete price, bears all overrun risk, premium of 5-10%. Best for well-defined scopes. Cost-plus: actual cost plus 12-20% management fee, open-book transparency, more flexibility for unknown conditions. Best for heritage homes and gut renovations.
Required for structural changes, additions, basement finishing, new bathrooms, plumbing relocations, new electrical circuits, decks over 24" above grade, and window opening changes. Your residential GC handles the permit application and inspection coordination as part of their service.
