Delivery and Set Day: How a Modular Home Gets from the Factory to a Lake Country or Vernon Lot
Most of the modular home buying conversation happens indoors. Models, finishes, floor plans, timelines. Then there is one day, usually lasting a matter of hours, when the house you have been looking at on paper arrives on the back of a truck and is craned onto a foundation.
That day is worth understanding in advance, because it is where the largest avoidable costs live and because almost everything that can complicate it is decided months earlier, when you choose the lot.
What set day actually looks like
The sequence is roughly the same everywhere, scaled to how many modules the home is built from.
The site has to be ready before anything moves. The foundation or pier system is complete and cured, it has been surveyed and confirmed square and level to tight tolerance, the utilities are stubbed where the drawings say, and there is a compacted, drained working area around it. A foundation that is 30 millimetres out of level is a problem you find out about with a house hanging from a crane.
The modules travel under permit. A house module is an oversize load. Transport requires provincial permits, a defined route, often pilot vehicles, and travel within permitted hours. Route approval is the constraint that matters and it is not negotiable on the day.
The crane arrives first. A mobile crane is set up, outriggers deployed on suitable ground, and the lift radius and capacity confirmed against the module weights. Crane selection is a function of how much the module weighs and how far the crane has to reach, and reach costs capacity. A crane that must sit further back because of a slope, a fence, a power line or a neighbouring structure needs to be a bigger crane.
Each module is lifted and set. Rigged, lifted, swung over the foundation and lowered onto it, positioned and then fastened down. This is the part people film. It is quick and it looks effortless because the work happened in the preceding weeks.
The modules are joined. The mate line between modules is closed up, structural connections made, and the roof, if it ships folded or in sections, is raised and completed.
Then the site work begins, and it is the longer part. Utility connections, the marriage line finishing inside, flooring across the joints, siding and roofing at the seams, decks, stairs, skirting, grading and landscaping. The house is on the ground in a day. It is finished considerably later.
The costs buyers do not see coming
The home price is the home. These are the separate lines, and they are the ones that vary enormously between one Okanagan lot and another.
Transport. Priced by distance, by the number of modules, and by the complexity of the permitted route. A straight run up Highway 97 is one thing. A final kilometre on a narrow, winding rural road is another.
Pilot vehicles and any traffic control. Required for oversize loads on most routes.
The crane. Usually the largest single day rate on the project. It is priced by capacity and by time, including mobilisation to and from site. A crane that sits waiting because the site was not ready is charged for.
Site access preparation. This is the sleeper cost. The truck has to physically get there, turn, and be positioned. That can mean widening an approach, removing or limbing trees, temporarily taking down a fence, reinforcing or building a temporary access road over soft ground, or arranging with a neighbour for swing room.
Utility conflicts. Overhead power lines crossing the approach or the lift zone are a common and expensive surprise. Temporarily de-energising or relocating a service line is arranged with the utility, costs money, and takes lead time. This should be identified at the site assessment, not on the morning of the set.
Foundation or pier system, which is its own scope with its own cost, plus excavation, backfill and drainage.
Utility connections: water, sewer or septic, power, and gas where applicable, from the property connection to the home.
Finishing after the set: decks, stairs, skirting, driveway, landscaping and final grading.
Permits and inspections through the local authority, which in this region means the City of Vernon, the District of Lake Country, the City of Kelowna or the relevant regional district, each with their own process and timelines.
In a developed community where the pads, services and access are already engineered for this exact purpose, most of these are known and priced. On a private lot they are variable, and the variability is the reason two identical homes can land at very different total costs.
Why the lot decides the price
If you are buying a home to place on land you own, or land you are choosing, assess these before you commit.
Road access all the way in. Width, turning radius at every corner, overhead clearance from trees and wires, weight limits on any bridge or culvert, and seasonal load restrictions. An oversize load cannot reverse out of a mistake.
Slope. A steep or awkwardly shaped lot affects the crane position, the foundation design, the drainage and the site preparation. Slope is the most common reason an Okanagan lot costs more to build on than a flat one.
Soil and bearing. The foundation design depends on what is under it, and a geotechnical assessment may be required. Outrigger loads from a crane also need ground that can carry them.
Setbacks and the placement envelope. Where the house can legally sit, which determines where the crane can sit.
Services. Whether water, sewer, power and gas are at the lot line or a long way from it, and whether the site is on septic, which brings its own approval and design process.
Overhead and underground utilities on the approach, identified early.
Seasonal timing. Frost, saturated spring ground and winter weather all affect excavation, concrete and site access. Scheduling a set for a period when the ground can take the equipment is a real planning consideration in this valley.
A reputable supplier will do a site assessment before quoting the site costs. Treat a supplier who quotes site work without visiting the lot with caution, because that number is a guess.
What can go wrong, and how it is usually prevented
The foundation is not right. Out of level, out of square, or the anchor points do not align with the module. Prevented by an as-built survey of the foundation before delivery, which is a standard and inexpensive check that is occasionally skipped.
The site is not ready when the crane arrives. The most expensive failure mode, because a crane and a crew standing idle bill for the day. Prevented by a written readiness checklist confirmed several days before, not the night before.
The route turns out to be impassable. Prevented by the transporter physically driving the route in advance, which good ones do.
Weather. Wind is the one that stops a set. Cranes have wind limits and a module is a large sail. A delivery day is weather dependent and the contingency plan should be discussed up front.
Transport damage. Modules are built to travel and it is uncommon, but the inspection on arrival, before the modules are joined, is the moment to document anything. Walk it with a camera.
Questions to ask before you sign
- What exactly is included in the delivered price, and what is quoted separately?
- Who is responsible for the site being ready, and what happens financially if it is not?
- Has the route been confirmed, and by whom?
- Who arranges the crane and who carries the risk if it waits?
- Who holds the permits for transport, and who holds the building permit?
- What insurance covers the home while in transit and during the set, and when does it transfer to me?
- What is the realistic window between the factory completing the home and the set date, and where is the home stored if the site is delayed?
- What is the schedule for completing the marriage line, the exterior and the site work after the set?
Frequently asked questions
How long does the actual set take?
A single or two module home on a prepared foundation is commonly a matter of hours for the lift itself. The wider delivery day, including crane setup and takedown, is a full day. Larger, multi module homes take longer.
Can I be there to watch?
Usually yes, from a safe designated area outside the work zone. It is a crane lift on an active site, so expect to be kept back and to follow the crew's direction.
Is a modular home weaker because it was moved?
The opposite argument is normally made. Modules are engineered to withstand transport and lifting loads that a site built house never experiences, which requires additional structure. Factory construction also happens indoors, so the materials are never rained on during the build.
What if my lot is difficult?
Difficult does not mean impossible. It means the site costs are higher and need pricing accurately before you commit. Get the site assessment done before firming up a purchase, not after.
Does the home arrive finished?
Largely. Interior finishes, cabinets, fixtures and often flooring are complete from the factory. What remains is the joint between modules, the exterior at the seams, and everything that connects the house to the ground and the services.
Can a modular home be moved again later?
Technically sometimes, practically rarely, and never cheaply. Plan the placement as permanent.
