How a Structural Renovation Actually Runs

What makes a renovation "structural" — and why it runs differently

Most renovations stay inside the lines the house already draws: new cabinets, new floors, a reconfigured bathroom. A structural renovation changes the bones. You are opening up a floor plan by taking out a wall that holds the house up, adding a storey, underpinning to gain a basement, levelling floors that have settled, or rebuilding framing that has failed. The common thread is that the load path — how weight travels from the roof down through the walls and beams into the foundation and the soil — is being altered.

That one fact changes everything about how the job runs. It needs a structural-capable builder, stamped engineering, more permit scrutiny, and a build sequence where some steps simply cannot happen out of order. It also attracts a different kind of risk: get a finish wrong and you redo a finish; get a load path wrong and the consequences are serious. This page is written for the owner of that kind of job — if you are planning a major home renovation, this is the process you are signing up for.

It starts with a structural engineer, not a sledgehammer

The single biggest difference between a structural renovation and a cosmetic one is where it begins. Cosmetic work begins with a mood board. Structural work begins with a structural engineer — and, on the North Shore's steep and variable lots, often a geotechnical engineer too.

Before anything is demolished, the engineer assesses the existing structure, works out the new load paths, and produces stamped drawings: beam sizes, post locations, connection details, foundation and footing specifications. Those drawings are what the municipality permits, what we build to, and what the inspector checks against. If you are not sure yet whether your project even needs this, our structural check is a sensible first step, and our guide on choosing a structural specialist explains the distinction. We are comfortable in this territory — we coordinate closely with the engineer so the design is buildable, not just correct on paper, and we flag practical issues early while they are still cheap to solve.

Permits and the paper trail

Structural work almost always needs a building permit, and the review is more thorough than for a straightforward interior refresh. The District or City of North Vancouver, or the District of West Vancouver, reviews the architectural and stamped structural drawings before issuing the permit, and may require letters of assurance committing the engineer to field review during construction.

This stage has its own timeline, and it is one of the places renovations stall when owners try to navigate it alone. Part of what we do is manage the submission and the back-and-forth so the project keeps moving. On older houses, a structural renovation is also a natural moment to fold in seismic upgrades — because the walls are already open and the engineer is already involved, the incremental cost of doing it properly is at its lowest. It is far cheaper to engineer and permit it once than to come back for it later.

What a structural-capable builder does differently

Plenty of renovators can hang drywall and tile a floor. Far fewer are set up to safely remove a load-bearing wall, temporarily shore a house while a beam goes in, or pour concrete to spec for a new footing or foundation element. That capability is the whole point of hiring a structural builder.

In practice it shows up as temporary shoring that is engineered rather than improvised, beam and post installs executed exactly to the connection details on the drawings, and poured concrete placed with the right formwork, reinforcement, and cure time instead of being rushed to keep a schedule. It also shows up in judgement: a crew that has opened a lot of walls knows that what you find behind them is rarely exactly what the drawings assumed, and knows how to respond without derailing the whole job. For work that joins old and new structure — a renovation or addition — that experience is the difference between a seam that disappears and one that cracks.

Hold points and inspections during the build

A structural renovation is built around hold points — moments where work stops until something is checked and signed off before it gets covered up. This is the opposite of how a cosmetic job runs, and it is deliberate: once concrete is poured or a wall is closed, fixing a mistake means undoing finished work.

Typical hold points include excavation and formwork inspected before a pour, rebar and foundation work reviewed before concrete, and framing — beams, posts, connections — inspected before anything is sheathed or boarded over. On permitted structural jobs the engineer performs field reviews at these stages and the municipal inspector signs off at theirs. Good sequencing means these never become a bottleneck: we plan the schedule around them so the right people are booked before the crew is ready to cover anything up, not after. When you see a structural renovation pause for a day, that pause is usually the process working correctly.

How to avoid mid-reno surprises

The surprises that blow up structural renovations are almost always discovered, not invented — a beam that turns out to be undersized, soil that behaves differently than assumed, or framing that has quietly deteriorated behind a finished wall. You cannot eliminate every unknown on a house that may be decades old, but you can decide in advance how they will be handled.

Three things help most. First, do the investigation up front: the more the engineer can confirm before demolition, the fewer assumptions the budget rests on. Second, insist on a clear, written scope and an honest contingency, with change orders priced and approved as they come up rather than absorbed silently. Third, hire for the hard part — the finishes are the easy 80%; it is the structure that determines whether the project is smooth or painful.

One specific case is worth naming. If, during a structural renovation, we uncover water damage or rot, we handle the structural repair — rebuilding rotted framing, beams, joists, or sheathing back to the engineer's spec so the house is sound again. The weatherproofing side of that repair — the envelope, membranes, and anything that keeps water out going forward — is specialized, licensed work, and we bring in a licensed envelope contractor for it rather than stepping outside our lane. That honesty about scope is part of how we keep a structural job from turning into an open-ended one. You can see the kind of work this covers on our North Vancouver service page.

Frequently asked questions

Do I need a structural engineer for my renovation?

If your project changes how the house carries its weight — removing or altering a load-bearing wall, adding a storey, underpinning, levelling settled floors, or rebuilding failed framing — then yes. The engineer produces the stamped drawings the municipality permits and that we build to. If you are not sure your project qualifies, a structural check is the right first step, and we can tell you quickly whether engineering is needed.

What is the difference between a structural renovation and a regular renovation?

A regular renovation stays within the existing structure — finishes, fixtures, reconfigured non-load-bearing space. A structural renovation changes the load path: the way weight travels from the roof down through walls and beams into the foundation. That difference means stamped engineering, a more thorough permit review, engineered shoring and framing, and a build sequenced around inspection hold points. It is a different kind of project, not just a bigger one.

Will you work with my architect and structural engineer?

Yes. We build to your engineer's stamped drawings and coordinate closely with them and your architect throughout, including the field reviews a permitted structural job requires. If you do not already have an engineer, we can point you to ones we trust. We like to be involved early, while the design is still being drawn, so we can flag buildability issues while they are cheap to solve.

We found rot or water damage mid-project — can you handle it?

We handle the structural side: rebuilding rotted framing, beams, joists, or sheathing back to the engineer's specification so the house is structurally sound again. The weatherproofing and building-envelope side of that repair is specialized, licensed work, so we bring in a licensed envelope contractor for it rather than taking it on ourselves. You get the structure fixed properly and the envelope handled by the right trade.

How long does a structural renovation take?

It depends entirely on scope — removing one wall is very different from underpinning a basement or adding a storey. The honest answer is that engineering and permitting happen before any demolition and have their own timelines, and the build itself is paced around inspection hold points that cannot be skipped. We give you a realistic schedule alongside a fixed-scope quote before work begins, so the timeline is something you agree to up front rather than discover as you go.
