Kitchen Odours in Quebec Co-ownership: Solutions and Remedies

Updated as of 2026-07-05. In a divided co-ownership, kitchen odours can quickly become a major irritant. They seep through corridors, travel up exhaust shafts and sometimes end up in neighbouring private portions. Between co-owners’ rights, the syndicate’s obligations and the technical constraints of ventilation, a structured approach is needed to ease tensions and correct the causes.

This practical guide, intended for boards of directors and condominium managers, explains how to diagnose odour sources, which rules apply under the declaration of co-ownership and the by-laws of the immovable, and which technical interventions should be prioritized to restore harmony in your condominium.

Where Do Odours Come From? Understanding the Causes in a Condominium

Kitchen odours travel easily when a building is not mechanically balanced. Here are the most frequent causes in divided co-ownership:

• Kitchen hoods in recirculation mode, with saturated or improperly installed charcoal filters.
• Defective backdraft dampers on exhaust ducts, allowing air to flow back towards other units.
• Negative air pressure in a unit (e.g., dryer, hood, HRV/ERV) that draws air from corridors or common shafts.
• Poor balancing of ventilation and make-up air systems on the floors, causing air currents towards door seals and electrical outlets.
• Insufficient sealing of unit entrance doors (weatherstripping, thresholds, door closers), allowing odours to escape into the common portions.
• Dirty or obstructed common ducts, reducing exhaust flow and creating backdrafts.

From a regulatory standpoint, building ventilation is governed by the Regie du batiment du Quebec (RBQ). Regular maintenance and compliance with recommended ventilation performance levels help limit odour transfer. Consult the RBQ for ventilation and mechanical-system maintenance requirements.

Legal Framework: What the Declaration, By-Laws and Civil Code Say

Quebec law recognizes both tolerance for normal neighbourhood inconveniences and protection against abnormal disturbances. In divided co-ownership:

• The Civil Code of Quebec governs the use of private portions and common portions. Co-owners must use their portions without interfering with others and must comply with the by-laws of the immovable (see, in particular, sections 1063 and 1072 C.C.Q.).
• The principle of “normal neighbourhood inconveniences” (section 976 C.C.Q.) applies: cooking inevitably produces odours, but excessive odours may constitute an abnormal disturbance if they are repetitive, intense and avoidable.
• The declaration of co-ownership and the by-laws of the immovable may establish rules concerning the use of hoods, filter maintenance, the hours when noisy appliances may be used and administrative sanctions for non-compliance.

For more information:

• Civil Code of Quebec – C.C.Q. (section 976: neighbourhood relations)
• C.C.Q. (section 1063: obligations concerning use in divided co-ownership)
• C.C.Q. (section 1072: contents of the by-laws of the immovable)
• RGCQ – Resources and best practices in co-ownership

The board of directors must apply the declaration of co-ownership and the by-laws consistently and in a documented manner. If the current rules are silent on ventilation or hood maintenance, the board of directors may propose amendments at the next annual general meeting, with legal advice if necessary.

Practical Solutions: From Individual Behaviour to Common Work

Correcting odours often requires a combination of occupant habits and technical interventions. We suggest a gradual and measured approach.

Good Practices to Remind Co-Owners and Occupants About

• Use the hood as soon as cooking begins and leave it running for 10 to 15 minutes afterwards, at the proper setting.
• Clean or replace grease filters every month; replace activated-carbon filters every 3 to 6 months, depending on use.
• Cover pots and reduce repeated frying; briefly air out the kitchen in winter in a controlled manner to avoid depressurization.
• Close the unit door while cooking to prevent odours from reaching the corridor; keep the entrance door airtight (weatherstripping in good condition).
• Manage food waste (closed bins, frequent removal) and clean surfaces and fans.

To encourage compliance, create and distribute a “Good Condominium Cooking Practices” sheet and archive proof of its distribution in the building’s records.

Inspections and Maintenance Paid for by the Syndicate (Common Portions)

• Inspection of kitchen exhaust shafts and backdraft dampers; periodic professional cleaning of ducts and exhaust housings.
• Inspection and balancing of the ventilation system, including make-up air for corridors and stairwells; adjustment to maintain slight positive pressure in the corridors.
• Inspection program for entrance doors (sealing, door closer, threshold) and replacement of deteriorated weatherstripping.
• Audit of hoods that are not connected to the exterior; if required by the declaration of co-ownership or permitted by the configuration, plan a compliant connection to the exterior exhaust.
• Update of the maintenance logbook/EUC to include the duct-cleaning frequency and rebalancing of airflow rates.

If necessary, issue a call for tenders to contractors holding the appropriate RBQ licence. Keep reports and photographs in the records and summarize the decisions in the board of directors’ minutes.

Targeted Work in Certain Units (Private Portions, Where Necessary)

• Replacement of ineffective hoods; addition of high-performance backdraft dampers compatible with the common shaft.
• Sealing of penetrations (outlets, baseboards, shafts) at fire-separation boundaries, carried out by a qualified contractor.
• Balancing of airflow rates at the grilles (if permitted by the declaration of co-ownership and the by-laws), with a measurement certificate.

These interventions often require close coordination between the co-owner and the syndicate. Verify the allocation of costs under the declaration of co-ownership and according to the portions concerned (common, common for restricted use, private).

Managing Complaints: Method, Evidence and Possible Sanctions

Rigorous complaint management helps distinguish normal from abnormal conditions and supports any corrective action.

1. Receipt and documentation
   Acknowledge receipt to the complainant and open a file. Request an incident log: dates, times, duration, perceived intensity and affected areas.
2. Fact-finding
   Gather statements from other occupants; conduct an odour inspection at the reported times, ideally with two people.
3. Gradual communication
   Send a courteous notice to the occupants concerned, reminding them of good practices and their obligations under the declaration of co-ownership and by-laws.
4. Temporary measures
   Propose quick fixes (filter cleaning, hood adjustment, weatherstripping) and schedule a technical inspection if required.
5. Regulatory sanctions
   If the by-laws provide for fines and a breach has been documented, apply them proportionately and fairly, with evidence kept on file.
6. Formal remedies
   In the event of a persistent abnormal disturbance, a formal demand may be sent. If there is no cooperation, an application for an injunction or damages may be considered, on legal advice.

Remind co-owners that common expenses must always be paid; an odour dispute does not justify withholding their contributions. Any agreement or measure must be recorded in the board of directors’ minutes and, if necessary, presented to the annual general meeting for information or ratification.

• RGCQ – Complaint management and by-law enforcement

Long-Term Prevention: Odour Policy, Budget and Maintenance Logbook

A prevention strategy reduces the risk of conflicts and unexpected expenses.

• Odour and ventilation policy
  Adopt, through the by-laws of the immovable, minimum requirements for hood maintenance (e.g., proof of filter replacement), permitted connections and door-sealing standards.
• Maintenance schedule and EUC
  Record in the maintenance logbook/EUC: semi-annual shaft inspections, annual duct cleaning based on use, and mechanical rebalancing every 2 to 3 years.
• Budget and contingency fund
  Include recurring maintenance in the operating budget. If a major ventilation improvement project is required, assess its eligibility for the contingency fund based on the declaration of co-ownership and the nature of the work.
• Information and training
  Upon purchase or rental, provide a welcome memo explaining kitchen practices, how hoods work and the remedies available when a problem arises.
• Compliance monitoring
  Keep a register of interventions, including photographs, reports and certificates. This facilitates board of directors’ decisions and transparent communication with co-owners.

FAQ – Kitchen Odours in Divided Co-ownership

Can Certain Foods Be Banned in a Condominium?

A general ban on foods is delicate and often difficult to justify. What can be enforced are obligations of means: hood maintenance, compliant connections, door sealing and respect for quiet enjoyment. If a particular preparation causes an abnormal and avoidable disturbance, the board of directors may intervene based on the by-laws of the immovable and the evidence.

Is a Recirculating Hood Acceptable?

It may be tolerated if permitted by the declaration of co-ownership and the by-laws, but its effectiveness is limited. Charcoal filters do not capture all odour molecules. Where possible, a compliant connection to the exterior through the common system remains preferable. In any event, filter maintenance is essential.

Can I Withhold My Condo Fees If My Neighbour Is Bothering Me?

No. Contributions must be paid in accordance with the declaration of co-ownership. You may, however, file a documented complaint, ask the syndicate to intervene and, in the event of inaction or a persistent abnormal disturbance, consult a legal professional to assess the appropriate remedies.
