What a feasibility study is — and isn't
A development feasibility study is the complete underwriting of a site. It takes one parcel and resolves the only question that matters before money is committed: should anything be built here, and if so, what? Its output is a go/no-go backed by the full reasoning — capacity, design, cost, and capital, held together so the answer survives scrutiny from a lender or a board.
It is not a pro forma. A pro forma is a single financial projection of one assumed building; the feasibility study is the larger question that produces the pro forma as one of its outputs. It is not a market study either — a market study reads demand, rents, and absorption, which the feasibility study consumes as an input rather than its conclusion. The point of the study is the synthesis: the place where the building, the entitlement path, the rents the zone supports, and the financing stack are forced to agree on a single number — or shown that they can't.
Because the stages of a development are interdependent — a decision in design can break the financing, an entitlement constraint can rule out the unit mix the rents needed — the highest-leverage moment in the entire arc is the first read. By the time design begins, the parcel's capacity, the path through approvals, and the achievable economics are largely fixed. The feasibility study is where they get fixed deliberately, rather than discovered one expensive stage at a time. For the full arc this study sits at the front of, see how development works in Halifax.
A feasibility study answers four questions, and the order matters — each constrains the next.
- What can this parcel support?
- What's the optimal thing to build here?
- Does the capital stack clear at the rents the zone supports?
- Should it be built at all?
What can this parcel support?
The first question is the parcel's development capacity: its zoning, permitted height, heritage and floodplain status, and the density-bonus envelope the zone may allow. This is the constraint everything downstream inherits, so it has to be read precisely.
Capacity is a property of the specific parcel — not a lookup-table number. Two lots in the same zone can support very different buildings once setbacks, frontage, grade, heritage overlays, and the bonus rules are applied. That is why a feasibility study computes capacity for the parcel rather than quoting a figure off a zone label. The official zoning reference for any HRM property is the City's own ExploreHRM tool; for the underlying concepts, our as-of-right and density-bonusing definitions, and the journal primer on what you can build on a Halifax lot, frame what the study resolves into a number.
The capacity read also sets the entitlement path — whether the project moves as of right or requires a development agreement — which in turn determines the schedule and the risk profile the rest of the study has to price.
What's the optimal thing to build here?
A single parcel can become an enormous number of different buildings. The right one isn't found by drawing a scheme and testing it; it's resolved by treating capacity, program, unit mix, structure, and cost as one coupled problem and searching for the configuration that maximizes the parcel's value across the whole stack.
This is the part a human team can't do by hand: the search space is too large to walk, and the variables loop — unit mix moves structure, structure moves cost, cost moves financing, financing moves back to unit mix. A few schemes can be tested in a few weeks of senior time; the optimum is never reached that way. Helio computes the whole space at once and prices every coherent building against its database of developments across the city, then returns the one configuration where the building, the money, and the delivery team all agree. The full argument for why this can only be computed lives on the development-process guide.
The result is a specific building — its massing, its unit mix, its structural system — not a vague range. That specificity is what makes the next two questions answerable.
Does the capital stack clear?
With a specific building resolved, the study tests whether it can be financed and whether the economics hold at the rents the zone supports. That means assembling the capital stack — debt and equity — and checking program fitness where it applies.
For multi-unit rental, the most consequential program is often CMHC MLI Select, whose points system can unlock higher leverage and longer amortization in exchange for affordability, energy, and accessibility commitments. Whether a project should reach for those points — and which ones it can credibly commit to without breaking the pro forma — is itself a modeling question the study resolves. The stack either clears at the achievable rents, or it doesn't, and the study says which, with the reasoning attached.
This is where the difference between a study and a pro forma is sharpest. A pro forma assumes a building and projects its numbers; the study asks whether that building should have been the one assumed in the first place, and re-solves if the stack won't clear. See the pro forma definition for the distinction.
Should it be built at all?
The final question is the honest one. After capacity, optimal design, and the capital stack are resolved, the study returns a go or a no-go — and a no-go is a real, valuable answer.
A study that says a project shouldn't proceed has saved months of effort and a great deal of capital that would otherwise have been spent learning the same thing the slow way. The document is yours either way — lender- and board-ready, with the full reasoning intact. Helio only runs the projects that should be run; the feasibility study is how that line gets drawn before commitment, not after.
What you receive
The deliverable is a complete, inspectable underwriting of the site: the capacity read, the resolved building, the capital stack, and the go/no-go, each backed by the reasoning that produced it. It is written to be read by the people who decide — a lender's credit committee, a board, a co-investor.
For investors and partners weighing a deal, the same document is the basis for an inspectable read of the underwriting rather than a pitch to be taken on trust — the framing that the investors & partners path is built around. The study is yours regardless of the verdict.
How an engagement begins
With Helio, the feasibility study is the first step. It's a fixed fee, agreed up front, and credited toward the development fee if the project proceeds. Helio is paid a development fee — a defined percentage of project cost — not equity in the building; you own the land and the finished building throughout, and construction is delivered by established builders Helio selects and manages.
To begin, Helio engages owners and developers with a real project — land owned or a specific parcel under serious consideration — and a timeline. The study is exactly how you decide whether to commit to the parcel, so you don't need a finished plan to start; you need a site and a question. For non-profits developing affordable rental, the same study models the funding-program stack alongside the building — see developing affordable & non-profit housing in Halifax.

Start with owners & developers →Feasibility vs. pro forma vs. market study
These three are often conflated. They sit at different scopes, and a feasibility study contains the other two.
When someone asks "what's the difference between a feasibility study and a pro forma," this is the short version: the pro forma answers how do the numbers look for this building; the feasibility study answers which building, and should it exist.
