Airbnb · Châteauguay · 2026 rules
Can you rent out your principal residence on Airbnb in Châteauguay, and where is a unit bought for short-term rental allowed? The city's rules, checked against its by-laws on October 19, 2026, the Quebec framework and the purchase price of a house or condo according to Centris.
We found no municipal restriction on renting out a principal residence in Châteauguay; buying a unit to rent it on Airbnb year-round (tourist residence) is possible only in specific zones. To buy, count on $520,000 for a house and $390,000 for a condo at the 2026 median price (Centris). The city publishes little on the subject: have the rule for the zone of the address confirmed before any offer. Rules checked on October 19, 2026.
The short answer
We found no municipal restriction on renting out a principal residence in Châteauguay; buying a unit to rent it on Airbnb year-round (tourist residence) is possible only in specific zones. To buy, count on $520,000 for a house and $390,000 for a condo at the 2026 median price (Centris). The city publishes little on the subject: have the rule for the zone of the address confirmed before any offer.
Renting out your principal residence in Châteauguay: no municipal restriction found
We found no restriction adopted by the city on renting out a principal residence. No provision on the principal residence establishment was found in the chapters of zoning by-law Z-3001 published by the City (main uses updated September 2, 2026, additional uses updated December 2, 2025); no public notice on the subject was found.
By default, Quebec law prevents a municipal by-law from prohibiting the rental of a principal residence unless it was adopted under the adapted referendum procedure (s. 23). Before counting on it, have the zone of the address confirmed by the planning department: it issues the zoning compliance document required for registration.
Buying to rent year-round in Châteauguay: only in some zones
A unit that is not your principal residence, rented by the night or the week all year, is a "tourist residence". The law does not protect it: the city decides through its zoning where it is allowed.
Zoning by-law Z-3001 groups accommodation under the use code “hotel, motel and tourist homes (583)”, permitted only in zones whose grid allows it; the zones were not identified in an official source.

Quebec's rules, the same everywhere
- Registration is mandatory. Renting a unit to tourists for 31 days or less requires registration with the Ministère du Tourisme and a certificate renewed every year: $54 for a principal residence establishment, $156 for a general tourist accommodation establishment (tourist residence). Since April 9, 2026, the number must appear in every listing, social media included.
- The city decides where. The registration application must include a document from the municipality confirming that the use complies with its zoning (Tourist Accommodation Act, s. 5). A notice of non-compliance prevents the application from being filed.
- The principal residence is protected, but not without limits. Since March 25, 2023, a municipal by-law can prohibit renting out a principal residence only through a zoning amendment adopted under an adapted referendum procedure (s. 23). Several cities have done it, zone by zone.
- Principal residence means where you actually live. It is the address you give to most government departments and bodies. Since September 1, 2026, two proofs of principal residence are required at registration and at renewal.
- In a condo, the syndicate signs every year. You need the declaration of co-ownership allowing the operation or the syndicate's authorization, and since September 1, 2026 that consent is required at every renewal, not only the first time.
- Registration does not transfer. A seller's Airbnb income was earned under their file. The buyer starts over, under the rules in force on the day of the application.

Before making an offer in Châteauguay
- The zone of the address, not the city. In Châteauguay as elsewhere, the rule changes from one zone to the next. Ask the planning department for the exact zone and the use grid, or for the zoning compliance notice, before the offer.
- The declaration of co-ownership. For a condo, read the clause on rentals and the building's destination: a syndicate can refuse, and must now consent at every renewal.
- The seller's certificate. If the seller already operates, ask for the registration certificate (class, expiry date, number of units), not just the number. It will not be transferred to you.
- The return without Airbnb. Price the property as if short-term rental became impossible tomorrow: it is the only assumption that does not depend on a by-law or a syndicate vote. Our five checks before buying to rent short-term set out the order.
