Frequently asked questions

How much does adu cost?
Most adu falls between $1,418 and $4,396, with a typical figure near $2,497 per job. The low end is a straightforward job with no surprises; the high end covers complex scope, premium materials or urgent timing. It is worth testing that against a couple of quotes in Quebec.
What affects the price of adu?
No single factor decides it — scope, materials, access and timing all move the total, and the biggest swings usually come from access and scheduling. Local providers in Quebec can confirm how that applies to your area.
Is ADUs cheaper in smaller cities?
Often, but not always. Smaller markets can carry a travel or availability premium that offsets a lower local rate, so it is worth checking a nearby city before assuming the lowest published figure applies to you. In Quebec, that is worth confirming with a local provider before you commit.
How many quotes should I get for adu?
Two or three written quotes are enough to see the real market range. Compare the same scope side by side, and ask each provider what is excluded and what would change the price after the quote is accepted. The answer can shift with the Quebec market, so check locally.
