Double garage: what the gap really buys in Châteauguay
A double garage often comes with a bigger, newer house on a wider lot: the gap in the table compares two groups of houses, not the value of a garage alone. For a seller, a double garage is a selling point to put forward in the listing and photos; for a buyer, look at what the gap really buys (size, lot, area). A broker on our team compares your house with recent sales with the same number of garages in your area.
How to read these numbers
Median sale price of single-family houses sold on Centris in Châteauguay, by year, by the listing's "Garage (number)" field: exactly 1 garage, or 2 garages and more. A listing with no garage leaves the field blank: the "no garage declared" share is the rest of the total. Fewer than 10 sales in the year, or a median under 40% or over 250% of the median house: median left blank (n/a). 2026 runs from January to September.
