Is Your Home Worth Renovating?

The decision is structural, not emotional

Greater Vancouver homeowners come to us in two camps. One has lived in the house for fifteen years, hates the layout, and wants to "open it up." The other just bought a tired post-war bungalow on a great Burnaby lot and is wondering whether to renovate or start over. Both are asking the same real question — whether the existing house can carry the renovation they actually want — but neither has usually run the structural and zoning checks that decide the answer.

A renovation worth doing keeps the parts of the house that are sound and replaces the parts that aren't. A renovation that should have been a rebuild spends money to wrap a tired structure in a beautiful finish — and the tired structure does what tired structures do.

Four diagnostics that decide it

1. Foundation and structural shell. Pre-1980 Burnaby homes often have undersized footings, post-and-beam basements, and limited shear capacity. A structural engineer can tell you in one site visit whether the shell is worth keeping. The Engineers and Geoscientists BC practice guidance sets the baseline for what a structural review should cover.
2. Envelope condition. Cladding, sheathing, windows, roof, and air-sealing are where pre-1990s GVRD homes leak energy and water. The BC Housing residential construction guides document the assemblies and detailing that actually perform — and how to tell when an existing wall has to come off.
3. Mechanical and electrical age. A 60-amp panel, knob-and-tube remnants, or a 30-year-old gas furnace all push a renovation budget toward "may as well." Replacing the furnace alone is a decision the federal programs at Natural Resources Canada's Greener Homes are pushing toward heat pumps anyway.
4. Zoning headroom. If your current home uses 70% of allowable FSR and you want 30% more space, a renovation can extend it. If you want to double the footprint or add a storey, BC's small-scale multi-unit housing framework (SSMUH) under the Province's housing initiatives page and your municipal zoning bylaw decide whether that's even legal.

The honest math (without dollar figures)

We don't publish price ranges — budget is a private conversation, and any public figure misleads more than it helps. But the comparative math is real: when foundation work, structural reframing, mechanical replacement, and envelope rebuild all stack into the same project, you are functionally building a new house behind an old name. At that point the rebuild path is frequently cleaner, faster on certain Burnaby permit streams, and gives you a fully Step Code-compliant envelope from day one.

Conversely, when the structure is sound and the renovation is mostly cosmetic plus one wall move and a kitchen, a renovation is usually the right call. Most of our renovation projects sit somewhere in the middle — and the chapter on Scope & Design covers how to keep them from sliding.

The "secret rebuild" trap

The most expensive renovation outcome is one that started as a renovation and quietly turned into a rebuild three months in: foundation work that wasn't planned, a roof that had to come off, structural reframing because the existing shear walls weren't where the new openings needed to be. By the time the team realises it, the cost of the rebuild has been spent — but the result is still constrained by the original shell. A clean structural and envelope assessment up-front is the single best way to avoid this.

What we tell clients in a first call

Before any drawings or pricing, we walk through the four diagnostics above, look at your zoning, ask what you actually want the house to do for the next 15 years, and tell you which path the answers point to. Sometimes that's a full renovation. Sometimes it's a partial — main floor only, kitchen plus one bath, addition without touching the original. Sometimes it's a rebuild, and we say so even though it routes the project to our custom-home team instead. Honesty here costs us nothing and saves clients years.

If you're earlier in the process and want a structured walkthrough of how this decision compounds across the rest of a build, our Custom home vs. major renovation piece goes deeper.
