Feasibility studies in Toronto – a direct go, modify, or reconsider recommendation before a dollar of design fees is spent.

A residential feasibility study assesses whether a proposed project is viable – given the site conditions, the zoning constraints, the existing building conditions, the estimated cost, the anticipated timeline, and the homeowner’s goals – before design fees are committed to the scope. It is the exercise that answers the question: should we proceed with this project, and if so, on what terms?
The assessment has four components. Site and zoning: what the lot allows, whether the proposed scope fits within the permitted envelope, and whether a Committee of Adjustment variance is required. Existing conditions: what the existing building contains that affects the project scope — structural conditions, mechanical systems, envelope performance, and any conditions that add cost to a renovation scope. Cost estimate: a realistic cost range for the proposed scope based on current Toronto construction costs, including soft costs that are consistently omitted from early project budgets. Recommendation: a direct go, modify, or reconsider recommendation based on the findings.
The deliverable is not a report that documents uncertainty – it is a clear picture of what the project involves and a direct recommendation about whether to proceed. A feasibility study that concludes with a list of considerations rather than a recommendation has not done its job.

Most early project budgets underestimate the real cost for two reasons: soft costs are omitted, and the hard construction cost is estimated from published per-square-foot figures that do not reflect the specific conditions of the project.
Soft costs – design fees, permit fees, development charges for new construction, engineering fees, temporary accommodation during construction, moving costs, and contingency – typically add 20 to 30 percent above the hard construction cost for a renovation and 25 to 35 percent for new construction. These costs are real, they are predictable, and they are consistently missing from the early budget conversations that homeowners have with designers and contractors who are incentivised to get the project started rather than to give an accurate total.
Hard construction cost estimates from published figures – $300 per square foot for a renovation, $600 per square foot for new construction – are averages across a wide range of project types, specification levels, and site conditions. A renovation that requires significant structural work, mechanical system replacement, and envelope repair in addition to the finish scope costs significantly more per square foot than a renovation that is primarily cosmetic. A new construction project on a challenging infill lot with tight access and a complex structural condition costs more than a comparable project on a straightforward site.
A feasibility cost estimate accounts for the specific scope of the project – including the structural, mechanical, and envelope conditions that affect the hard cost, and the full range of soft costs that the total budget needs to absorb. It is not a number designed to get the project started. It is the number the project will actually cost.

A go recommendation means the project is viable as proposed – the zoning supports the scope, the existing conditions do not add significant cost beyond what the scope already anticipated, the cost estimate is within the homeowner’s budget, and the timeline is acceptable. The project can proceed to design engagement with confidence that the scope is buildable, permittable, and affordable.
A modify recommendation means the project is viable with adjustments – the proposed scope exceeds the lot coverage limit by a margin that a reduced footprint could resolve, or the estimated cost exceeds the budget by an amount that a specification adjustment or a reduced scope could address, or the Committee of Adjustment requirement adds a timeline that changes the project’s viability for the household’s situation. The modification that makes the project viable is identified specifically, not generally.
A reconsider recommendation means the project as proposed is not viable – the zoning does not support the scope and the variance required is unlikely to be approved, or the estimated cost significantly exceeds the budget with no obvious reduction that preserves the project’s value, or the existing building conditions add costs that make the renovation more expensive than the alternatives. A reconsider recommendation is not a refusal to help – it is an honest assessment that proceeding would likely produce a worse outcome than the alternatives, and an explanation of what those alternatives are.
Most firms do not give reconsider recommendations because they are in the business of getting projects started. We give them when the assessment warrants them – because a homeowner who proceeds with a project that was not viable from the beginning spends significantly more than one who redirected earlier.

A feasibility study makes sense before any renovation where the scope is large enough that getting it wrong is expensive – where the design fees, the construction cost, and the disruption of the project represent a significant commitment that deserves to be assessed before it is made.
For renovations specifically, the feasibility question is usually one of three: whether the proposed scope is achievable within the existing building’s structural and mechanical constraints without costs that exceed what the scope is worth; whether the lot coverage and zoning provisions support any additions to the building footprint that the scope involves; and whether the estimated cost is realistic given the specific existing conditions rather than a comparable project in better condition.
The renovations where feasibility assessment is most valuable are whole-home renovations of Toronto’s older housing stock – Victorian and Edwardian semis and detached homes where the existing conditions are variable, where the mechanical systems may be at end of life, and where the envelope performance may require significant investment to bring to a standard the renovation warrants. These are the projects where the gap between an early cost estimate and the real project cost is largest, and where the feasibility study investment produces the greatest return.

For new construction, a feasibility study is warranted before purchasing a lot or committing to a teardown – when the project viability depends on conditions that have not yet been confirmed. The zoning analysis that determines the permitted building envelope. The development charges that apply to new residential construction in Toronto and that add a significant cost that is consistently missing from early new construction budgets. The site conditions – access, topography, existing services – that affect the construction cost.
Toronto development charges for new residential construction currently run $80,000 to $120,000 per unit depending on the unit size and the applicable charges in the specific area. These charges are in addition to permit fees, design fees, and construction costs, and they are not negotiable. A homeowner who has budgeted for a custom home in Toronto without accounting for development charges has a budget gap of $80,000 to $120,000 that will become apparent at the permit application stage – at a point where the lot has been purchased, the design fees have been spent, and the only options are to find additional budget or to abandon the project.
A feasibility study before lot purchase or teardown commitment confirms the development charges, the zoning envelope, and the site conditions that affect the construction cost – so the total project budget is known before the commitment is made rather than discovered after it.

Site planning focuses on the physical and regulatory constraints of the lot – what the zoning allows, what the site conditions permit, and what the building envelope looks like. It answers the question: what can be built on this lot? It does not assess cost, timeline, or whether the project is worth pursuing.
A feasibility study incorporates the site planning findings and adds the cost estimate, the timeline projection, the existing building condition assessment for renovations, and the go/modify/reconsider recommendation. It answers the broader question: should we build this, and on what terms? Site planning is a component of a feasibility study, not a substitute for it.
For projects where the primary unknown is the zoning – a homeowner who wants to know if a garden suite is possible on their lot before thinking about cost or design – site planning is the right starting point. For projects where the homeowner is weighing whether to proceed at all – evaluating a lot purchase, deciding between renovation and new construction, or assessing whether a major renovation budget is realistic – a full feasibility study is the appropriate scope.

A feasibility study at Habitual Homes is the first stage of the design-build process for projects where viability needs to be confirmed before design fees are committed. The findings of the feasibility study – the confirmed zoning envelope, the existing condition assessment, the cost estimate, and the go/modify/reconsider recommendation – become the brief for the design that follows.
A project that proceeds from a feasibility study to design does so with the scope confirmed, the cost range established, and the zoning constraints understood. The design is developed within a confirmed framework rather than a set of assumptions that may not survive contact with the permit process or the construction estimate. The design fees spent on a feasibility-validated scope are design fees spent on a project that will get built.
Because the same team conducts the feasibility study and the design and construction, the findings are carried forward without loss. The existing conditions identified in the feasibility assessment inform the structural and mechanical strategy in the design. The cost estimate established in the feasibility study is the benchmark against which the construction documents are costed. There is no handoff between the firm that assessed the project and the firm that designs it.

We provide feasibility studies across Toronto and the GTA – Leslieville, East York, Riverdale, the Beaches, the Danforth, Leaside, Rosedale, Forest Hill, Lawrence Park, Midtown, North York, Scarborough, Mississauga, and Richmond Hill.
Toronto’s specific construction cost conditions, development charge structure, zoning bylaw provisions, and older housing stock conditions are the context within which every feasibility assessment is conducted.
