Room Rentals in a Quebec Condo: Rules for Co-owners

Shared accommodation in a divided co-ownership is attracting more and more co-owners and students in Montreal and on the South Shore. Renting rooms in a condo can optimize occupancy and reduce your condo fees. But between the declaration of co-ownership (DCV), the by-laws of the immovable, the lease and insurance, what does Quebec law say? Here is a practical guide, up to date as of 2026-06-04, to renting rooms while complying with your obligations and those of the syndicate.

What the DCV allows (and regulates) in shared accommodation

In a divided co-ownership, the DCV and the by-laws of the immovable establish the building’s intended purpose and occupancy rules. In principle, renting part of a private portion (your unit) is permitted, but it must comply with the intended purpose (e.g., residential) and the quiet enjoyment of the common portions.

• The board of directors (board) may impose reasonable procedures related to moving, occupant registration and safety (keys, intercoms and elevators).
• Clauses on the maximum number of occupants, pets, noise and the use of parking spaces are common and enforceable against tenants and co-tenants.
• The syndicate cannot remove a right provided for in the Civil Code of Quebec (C.C.Q.), but it may regulate use according to the building’s intended purpose and the by-laws of the immovable (see C.C.Q., sections 1039 to 1109; sections 1063 and 1064, LégisQuébec).

Always refer to your DCV, the by-laws and the decisions made following the annual general meeting. Requirements adopted at a meeting and recorded in the minutes apply to all occupants, whether they are co-tenants or subtenants.

Renting rooms: shared accommodation, subletting or separate leases?

The expression “renting rooms” covers several legal situations. Clearly distinguishing between these scenarios helps prevent disputes.

• Shared accommodation (co-tenants): all the people sign the same lease with the co-owner-landlord. They are generally jointly and severally liable for the rent and their rental obligations.
• Subletting: a person who is already a tenant transfers the use of a room to a third party with the landlord’s consent. Authorization cannot be refused without a serious reason (see C.C.Q., section 1870, LégisQuébec). In a co-ownership, the landlord is the co-owner, not the syndicate.
• Separate leases for each room: each occupant has a separate lease for a room and a right to use the common spaces within the unit. This arrangement creates more rental relationships and requires closer management of the internal rules.

Regardless of the arrangement, occupants must comply with the DCV, the by-laws of the immovable and the rules governing use of the common portions. Include a clear clause in the lease or an addendum requiring compliance with the co-ownership (by-laws, instructions, applicable penalties, etc.).

Useful clauses to include in your documents

• Handing over and returning keys/fobs and access to the intercom.
• Respecting quiet, prohibiting smoking as required by the by-laws, managing visitors and setting hours for using the facilities (pool, gym and terrace).
• An obligation to obtain tenant liability insurance and provide proof annually.
• An obligation to promptly report any water damage or loss affecting the private portions and, where necessary, the common portions.

Syndicate rules and the board’s role: do not overlook them

The board of directors administers the common portions and ensures that the DCV is applied. In a shared-accommodation context:

• Occupant registration: many syndicates require the co-owner to provide the co-tenants’ contact information and the lease terms for security and emergency purposes. This facilitates communication and compliance with instructions.
• Moving: time slots, elevator deposits and booking procedures may apply. Consult the directions in the by-laws of the immovable.
• Nuisances and quiet enjoyment: the board may intervene in cases involving noise, odours, clutter in corridors or use that is inconsistent with the residential purpose.
• Short-term rentals: these are often restricted or prohibited by the by-laws and the building’s intended purpose; do not confuse medium- or long-term shared accommodation with tourist-style lodging.

In the event of repeated violations, the syndicate may, depending on the DCV, impose reasonable penalties and pursue remedies (a formal demand or injunction). The co-owner remains responsible for the actions of their occupants with respect to common expenses and damage caused to the common portions.

Financial, insurance and compliance considerations

• Common expenses and assessments: condo fees remain the co-owner’s responsibility. More intensive occupancy may increase wear and tear; keep an eye on the maintenance logbook (EUC) and recommendations concerning the contingency fund.
• Insurance: inform your insurer that the unit is shared accommodation. Require tenant liability insurance from each occupant. Check exclusions relating to losses (e.g., water damage) and activities prohibited by the DCV.
• Taxation: rent collected generally constitutes rental income. Plan for the reasonable allocation of expenses (interest, taxes and maintenance) according to the space and period of occupancy. Consult Revenu Québec’s guidelines.
• Compliance and safety: comply with safety rules (smoke detectors, water-heater maintenance, etc.). No alteration may affect common elements without the syndicate’s prior authorization and, where necessary, the involvement of compliant contractors.

For a reminder of the applicable frameworks:

• Civil Code of Quebec – divided co-ownership and the obligations of co-owners and occupants (see sections 1039 to 1109, sections 1063–1064): LégisQuébec.
• Residential leases, subletting and assignment (e.g., see section 1870 C.C.Q.): LégisQuébec.
• Rental income (reporting and eligible expenses): Revenu Québec.
• Best practices in co-ownership (governance and by-laws): RGCQ and RGCQ – La copropriété.

Recommended procedure for a co-owner renting rooms

1. Review the co-ownership documents

   Read the DCV, the by-laws of the immovable and recent resolutions again (annual general meeting, minutes). Look for clauses concerning maximum occupancy, moving, deposits and the prohibition of tourist accommodation.

2. Choose the appropriate legal arrangement

   Determine whether you will use one common lease (co-tenants), separate leases for each room or a sublease. Specify how the spaces are divided: bedrooms (exclusive use) and common spaces (kitchen, living room and bathroom) within the private portions.

3. Draft a lease and addendum suited to the co-ownership

   Include a “co-ownership” addendum: compliance with the DCV, the by-laws, notices from the board, applicable penalties and instructions for the common and private portions. Include the tenant’s obligation to carry liability insurance and return the keys/fobs.

4. Register the occupants with the syndicate

   Send the occupants’ contact information and lease terms to the condominium manager or the board and, if applicable, reserve the elevator for the move.

5. Set up clear day-to-day management

   Create a schedule for the bins, cleanliness rules for the common spaces within the unit, a procedure for noise complaints and a communication channel for repairs (e.g., a leak or defective intercom). Keep records of notices and interventions.

6. Monitor maintenance and costs

   Document the condition of the premises (photos/videos). Complete the maintenance required in the maintenance logbook. Plan for replacements (e.g., a water heater) to prevent a loss and claims against the syndicate.

Risks to avoid and common remedies used by the syndicate

• Overcrowding and nuisances: too many occupants may contravene the residential purpose and the by-laws (noise, odours and comings and goings). The board may issue violation notices and, if necessary, pursue remedies.
• Unauthorized alterations: partitioning an open area to create a “bedroom” may affect ventilation, safety or common portions (the structure and windows). Obtain the required authorizations before making any modification.
• Failure to register occupants: this delays emergency communications, complicates parking management and affects access to the common portions (pool and gym). Many DCVs provide for penalties when occupants are not registered.
• Inadequate insurance: a loss caused by an uninsured occupant can be costly. The co-owner remains liable to the syndicate for damage to the common portions.

FAQ – Shared accommodation and co-ownership in Quebec

Can a syndicate prohibit shared accommodation in a condo?
In most cases, no. However, it may regulate use based on the building’s intended purpose, nuisances and safety rules. Occupants must comply with the DCV and the by-laws.

Can I sign a separate lease for each room?
Yes, if the DCV does not prohibit it and the use remains residential. This arrangement requires a clear addendum covering the use of the common spaces within the unit and compliance with the by-laws of the immovable.

Can the board require a copy of the leases?
The board may request the information needed to apply the by-laws (occupants’ contact information, occupancy period, proof of insurance and confirmation that the by-laws were provided). Its involvement in the other clauses of the lease is limited to compliance with the co-ownership and the law.

Who pays the condo fees and penalties?
Common expenses and assessments remain the co-owner’s responsibility. Penalties provided for in the DCV for occupants’ violations may be claimed from the co-owner, who may have recourse against the offending occupant under the lease.

Do I have to report income from my rooms?
Yes, rent is generally rental income. Consult Revenu Québec regarding the allocation of expenses and the tax impact.
