Short-term rentals can look attractive to real estate investors. Higher nightly rates, strong tourist demand, and flexible occupancy can make platforms such as Airbnb and Vrbo seem like an easy way to increase the revenue of a duplex, triplex, fourplex, or multiplex.
In Quebec, however, short-term rentals are heavily regulated. Provincial registration rules apply, municipalities can impose additional restrictions, and Montreal has some of the strictest local rules in the province.
For a plex investor, this means one thing: you should never assume that a property can legally operate as a short-term rental simply because similar listings appear online.
In this guide, Plex Guru explains the key rules investors should understand before incorporating short-term rental income into a Montreal or Quebec real estate strategy.
1. What Is Considered a Short-Term Rental in Quebec?
Quebec generally treats accommodation offered to tourists for periods of 31 days or less as tourist accommodation.
This can include:
- A house
- A condo
- An apartment
- A room
- A duplex, triplex, or fourplex unit
- A secondary residence
- Other furnished accommodation
If you offer accommodation to tourists for compensation for 31 days or less, provincial tourist-accommodation rules may apply. :contentReference[oaicite:0]{index=0}
2. Provincial Registration Is Required
In Quebec, tourist accommodation establishments generally need to be registered before they can legally be offered for short-term rental.
The registration process is administered through the province’s tourist-accommodation system, with applications for many accommodation categories handled through the Corporation de l’industrie touristique du Québec (CITQ).
Before applying, operators must obtain municipal confirmation that the intended use complies with local zoning and urban-planning regulations. :contentReference[oaicite:1]{index=1}
This is extremely important for investors because provincial registration does not override municipal zoning.
3. Municipal Rules Come First
A common mistake is assuming that obtaining a provincial registration number means a property can automatically operate as a short-term rental.
It cannot.
The municipality must first allow the intended use.
Depending on the location, the municipality may:
- Allow short-term rentals
- Restrict them to certain areas
- Restrict them to principal residences
- Require an occupancy permit
- Limit the time of year rentals are permitted
- Prohibit commercial tourist accommodation entirely
For investors, municipal zoning should therefore be verified before purchasing the property.
4. Montreal Has Its Own Short-Term Rental Rules
Montreal imposes additional rules on top of Quebec’s provincial requirements.
As of 2026, Montreal distinguishes between short-term rental of a person’s principal residence and commercial tourist accommodation operated from a property that is not the owner’s principal residence. :contentReference[oaicite:2]{index=2}
The rules can vary substantially depending on the borough and property.
5. Principal Residence Rentals in Montreal
Montreal allows eligible residents to rent their principal residence to tourists under specific conditions.
For most participating boroughs, the city currently allows principal-residence tourist rentals from June 10 to September 10.
The property must genuinely be the operator’s principal residence. Owners must live there, and tenants must have authorization through their lease or written permission from the landlord. :contentReference[oaicite:3]{index=3}
A host permit is also required and must be renewed annually. :contentReference[oaicite:4]{index=4}
6. Some Montreal Boroughs Do Not Allow This Use
Montreal’s principal-residence tourist rental rules do not apply uniformly across every borough.
The city’s current rules exclude certain boroughs, including:
- Lachine
- Saint-Laurent
- Saint-Léonard
Investors should always verify the exact address and borough before assuming short-term rental use is permitted. :contentReference[oaicite:5]{index=5}
7. Commercial Short-Term Rentals Are Much More Restricted
For many investors, the more important question is whether an apartment that is not their principal residence can be rented repeatedly to tourists.
In Montreal, this is generally considered commercial tourist accommodation.
Commercial tourist homes are subject to borough zoning and may require an occupancy permit. Many boroughs prohibit them entirely or restrict them to specific commercial areas. :contentReference[oaicite:6]{index=6}
This means buying a triplex and automatically placing all three units on Airbnb may not be legally possible.
8. Rules Can Change From One Borough to Another
Montreal’s borough-based regulations are one of the biggest challenges for investors.
A use that is permitted on one street may be prohibited only a few blocks away.
Depending on the borough, commercial tourist accommodation may:
- Be prohibited throughout the borough
- Be permitted only on designated commercial streets
- Require a certificate of occupancy
- Require minimum distances between establishments
- Require additional approval from the borough
For example, Montreal’s current guidance identifies several boroughs where commercial tourist accommodation is completely prohibited, while others permit it only in narrowly defined zones. :contentReference[oaicite:7]{index=7}
9. Never Rely on Existing Airbnb Listings as Proof
Seeing multiple Airbnb listings in a neighbourhood does not prove that short-term rentals are permitted there.
Some listings may be:
- Grandfathered
- Operating under a different zoning category
- Operating from principal residences
- Operating illegally
- Located in a different zoning sector
The only reliable approach is to verify the zoning and permits for the specific property you are considering.
10. Registration Requires Municipal Compliance
Before applying for provincial tourist-accommodation registration, an operator must obtain an official municipal document confirming that the proposed tourist-accommodation use complies with local urban-planning rules. :contentReference[oaicite:8]{index=8}
This requirement creates an important safeguard for investors.
If the municipality does not allow the use, provincial registration cannot simply be used to bypass the restriction.
11. Liability Insurance Is Required
Quebec requires tourist-accommodation operators to carry liability insurance.
Current provincial registration requirements include proof of at least $2 million in civil liability coverage per event for bodily injury or property damage related to operation of the accommodation. :contentReference[oaicite:9]{index=9}
This coverage is separate from simply having a standard residential insurance policy.
Investors should confirm with their insurer that the property is properly covered for short-term rental activity.
12. Condo Rules Can Also Restrict Short-Term Rentals
If the property is held in divided co-ownership, the condominium declaration or syndicate rules may restrict tourist accommodation.
Quebec’s registration process may require authorization from the syndicate of co-owners when applicable. :contentReference[oaicite:10]{index=10}
Therefore, even if municipal zoning allows short-term rentals, the condominium’s own rules may prevent them.
13. Tenants Need Landlord Authorization
A tenant generally cannot simply start renting their apartment to tourists without authorization.
Quebec’s registration process requires landlord authorization when the operator is a tenant, and Montreal similarly requires authorization through the lease or written permission for principal-residence tourist accommodation. :contentReference[oaicite:11]{index=11}
For plex owners, this means lease terms should clearly address short-term rental activity.
14. Principal Residence Has a Specific Meaning
A principal residence is not simply a property that you own.
Under Quebec’s tourist-accommodation rules, it is generally the place where you ordinarily live and centralize your family and social activities, and where your address corresponds with the one you provide to government authorities. :contentReference[oaicite:12]{index=12}
Investors should not assume that designating an investment unit as a “principal residence” is enough to qualify.
15. Proof of Principal Residence May Be Required
Applicants seeking principal-residence registration may need to provide documentation showing that the property is genuinely their main home.
Quebec’s current registration process may request multiple supporting documents, such as government correspondence, tax documentation, vehicle insurance records, or other qualifying proof. :contentReference[oaicite:13]{index=13}
16. Registration Numbers Must Be Properly Displayed
Tourist-accommodation operators have obligations regarding their registration number and certificate.
This information may need to appear on listings and other advertising.
Investors should make sure that any property manager or booking platform is using the correct registration information.
17. Taxes Still Apply
Short-term rental income is taxable.
Quebec notes that revenues generated through tourist accommodation must be declared according to applicable tax laws.
Depending on the operation, investors may need to consider:
- Income tax
- GST
- QST
- Quebec lodging tax
The tax treatment depends on the nature and scale of the activity, so professional accounting advice can be valuable. :contentReference[oaicite:14]{index=14}
18. Short-Term Rental Income Should Be Underwritten Carefully
Even where short-term rentals are legal, investors should avoid building an acquisition strategy based solely on optimistic nightly rates.
Your analysis should account for:
- Seasonality
- Occupancy rates
- Platform fees
- Cleaning costs
- Property management
- Insurance
- Utilities
- Furniture replacement
- Licensing fees
- Taxes
- Vacancy
Gross short-term rental revenue can look impressive, while the actual net income is considerably lower.
19. Compare Short-Term and Long-Term Rental Income
Before choosing a short-term rental strategy, compare it with traditional long-term leasing.
For example, consider:
- Annual gross rent
- Operating costs
- Management requirements
- Vacancy risk
- Regulatory risk
- Tenant turnover
- Financing
A legal long-term rental with stable tenants may ultimately generate a stronger risk-adjusted return than a higher-maintenance tourist rental.
20. Regulatory Risk Should Be Part of Your Investment Analysis
Short-term rental laws can change.
A property that works under today’s regulations may face new restrictions later.
This makes regulatory risk especially important when purchasing a property at a premium based on anticipated Airbnb revenue.
A conservative investor should ask:
- Would this property still make sense as a long-term rental?
- Can the mortgage be supported without short-term rental revenue?
- What happens if municipal rules change?
If the entire investment only works because of short-term rental income, the acquisition may carry significantly more risk.
Short-Term Rentals in a Triplex or Fourplex
For Montreal plex investors, short-term rental regulations require particular attention.
Owning a triplex or fourplex does not automatically give you the right to operate every apartment as tourist accommodation.
Each proposed use must comply with:
- Provincial tourist-accommodation rules
- Municipal zoning
- Borough regulations
- Permit requirements
- Insurance requirements
- Lease or co-ownership restrictions where applicable
This should be confirmed before incorporating short-term rental revenue into your acquisition model.
Questions to Ask Before Buying
Before purchasing a property with a short-term rental strategy in mind, ask:
- Is tourist accommodation permitted at this exact address?
- Is the property in an authorized zoning area?
- Is this my principal residence or an investment property?
- Do I need an occupancy permit?
- Can I obtain provincial registration?
- Are there condominium restrictions?
- Will my insurer cover the activity?
- What taxes apply?
- Does the property still work financially as a long-term rental?
Why Work With Plex Guru?
A short-term rental strategy can completely change the projected financial performance of a plex, but only if that strategy is legal, realistic, and sustainable.
Plex Guru helps Montreal investors evaluate acquisition opportunities with a broader view of the property and its investment potential.
Before buying a duplex, triplex, fourplex, or multiplex, investors should consider:
- Zoning
- Rental strategy
- Current leases
- Potential income
- Operating expenses
- Financing
- Building condition
- Regulatory risk
The goal is not simply to maximize projected revenue. It is to build an acquisition strategy that remains financially sound under realistic conditions.
Final Thoughts
Short-term rentals can provide opportunities for Quebec real estate investors, but they operate within a strict regulatory framework.
In Montreal especially, provincial registration is only one part of the equation. Borough zoning, municipal permits, principal-residence rules, insurance, and taxation can all determine whether a short-term rental strategy is viable.
Before purchasing a property based on projected Airbnb or tourist-rental income, verify the regulations for the exact address and analyze how the property would perform under a traditional long-term rental model as well.
