Costs, Prices and Inclusions You Need to Know
A prefabricated home in Quebec (also called a factory-built home, modular home, or panelized home) is a house whose components are manufactured in a factory and then transported and assembled on-site.
This industrialized construction method allows better control over timelines, quality, and often costs. However, inclusions may vary from one builder to another.
How much does a prefabricated home cost in Quebec?
The price of a prefabricated home depends on the construction type, finish level, and project inclusions.
On average in Quebec:
- Shell home (basic structure): approx. $180 to $230/sq.ft. approx
- Semi-finished home: approx. $230 to $300/sq.ft. approx
- Turnkey home: approx. $280 to $400+/sq.ft. approx
- Prices are indicative only and subject to change at any time approx
Prices are indicative only and are subject to change at any time based on market costs/prices, the construction location, and transportation fees.
Prices vary depending on:
- Land and site conditions
- Fondation and excavation
- Level of customization
- Options and upgrades
- région within Quebec
Les prix varient en tout temps selon les marchés et les années de construction
What is not always included in the price
Even if the home is factory-built, several items may be excluded from the base price.
Land and site preparation
- Land purchase
- Site preparation
- Excavation and backfilling
- Foundation
- Site access
- Utilities (water, sewer, electricity, etc.)
- Fire place
Exterior elements
- Gutters (sometimes subcontracted)
- Balcony or deck
- Exterior landscaping
Basement
- Basement finishing
- Full basement insulation
- Basement windows
- Plumbing (bathroom / laundry room)
- Basement walk-out (often optional or extra depending on land and builder)
In a modular or factory-built home, the basement may be:
- Delivered unfinished (raw shell, uninsulated)
- Partially finished
- Fully finished
Insulation, finishing, and exterior access must be confirmed early in the project design phase with the manufacturer.
Prefabricated vs Modular vs Traditional
- Traditional: built entirely on-site
- Prefabricated / factory-built / modular: built in a factory and assembled on-site
Results:
- Faster construction
- Better quality control
- But offer structure varies by builder and region
Transparency and cost management
In the residential construction industry, inclusions vary significantly between builders.
Items such as excavation, foundation, basement work, exterior elements may be included, excluded, or subcontracted.
It is essential to obtain a detailed and transparent quote before making a decision.
Integrated construction approach
Some home manufacturers in Quebec use integrated cost and material management systems for both factory-built homes and custom turnkey projects.
The goal is to ensure better alignment between design, manufacturing, and construction, as well as improved budget visibility.

On average:
- Factory manufacturing: a few weeks
- Transport and installation: a few days to a few weeks
- On-site work: varies depending on the project
Total timeline depends on:
- Project complexity
- Building permit
- Site conditions
- Availability of crews and materials
- Construction season
Summary
A prefabricated, factory-built, or modular home in Quebec offers:
- More predictable costs
- Faster construction timelines
- Controlled factory quality
However, several elements such as excavation, foundation, basement work, and certain exterior tasks are not always included in the base price.
