Is a 10-Year Water Heater Replacement Rule Legal?

In many divided co-ownerships in Quebec, the board of directors is considering requiring water heaters to be replaced after 10 years. The objective is straightforward: reduce the risk of flooding, claims and rising insurance premiums. But is such a requirement actually legal? And if so, how can it be applied without infringing on co-owners’ rights?

This guide reviews the legal framework (declaration of co-ownership, by-laws of the immovable, and majorities at the annual general meeting), the usual responsibilities relating to private portions, and sound operational practices for a smooth and compliant rollout in Montreal and the greater metropolitan area.

Is it legal to require replacement after 10 years?

• The water heater is almost always located in a private portion. Unless the declaration of co-ownership provides otherwise, its maintenance and replacement are the responsibility of the occupying or leasing co-owner.
• However, the by-laws of the immovable may govern the use, maintenance and safety of the fractions in order to protect the building and the common portions (see section 1060 of the Civil Code of Quebec). A rule requiring preventive replacement of water heaters at a specified age is specifically intended to prevent damage.
• The adoption or amendment of the by-laws of the immovable is decided by the meeting of co-owners, according to the majorities set out in the Civil Code (particularly for rules of conduct and maintenance; see section 1096 of the Civil Code of Quebec).

In practice, many syndicates adopt by-laws specifying the maximum age (e.g., 10 years), technical requirements (drain pan, relief-valve discharge pipe, shut-off valves), required proof (invoice, serial number) and monitoring procedures. This approach is generally recognized as valid if it is properly adopted, respects the destination of the immovable and does not impose disproportionate constraints.

Legal points to consider:

• By-laws cannot contradict the declaration of co-ownership or transfer common expenses to a co-owner without a legal basis (see section 1064 of the Civil Code of Quebec regarding contributions). However, they may specify private-portion maintenance obligations intended to prevent claims.
• The syndicate retains the right to access private portions for maintenance, repairs and inspections necessary to preserve the building, with reasonable notice except in an emergency (see section 1069 of the Civil Code of Quebec).

Why 10 years? Risk, insurance and premium considerations

• Increasing risk of leaks: the steel tank wears down over time, while corrosion and mineral buildup increase the likelihood of a rupture.
• Financial impacts: a water claim can cost tens of thousands of dollars in repairs to common portions, without counting the syndicate’s insurance deductibles and multiple claims that affect the annual premium.
• Indirect insurer requirements: although insurers do not always impose a specific age, they favour mitigation measures (proactive replacement, drain pans and detectors) to maintain insurability and limit increases.

Some co-ownerships under our management have reduced the frequency of tank-related claims by adopting a clear replacement cycle and a simple document-control process (proof of age and compliance). This measure fits well with the maintenance logbook / EUC and periodic inspections.

How to adopt valid by-laws at the annual general meeting

1. Prepare the draft resolution

   • Define the scope: maximum age (e.g., 10 years), models covered, exceptions (commercial tanks, boilers), and minimum technical requirements.
   • Determine the required proof: invoice, manufacturing label (serial number), or a plumber’s certificate.
   • Set the deadlines: a grace period for water heaters already in service (e.g., 6 to 12 months).
   • Establish the monitoring process: a register of serial numbers maintained by the syndicate, annual updates and automated reminders.

2. Give notice of the annual general meeting

   • Include the resolution on the agenda, attach the proposed text to the notice of meeting and explain the reasons (claim prevention, protection of the contingency fund and common expenses).

3. Hold the vote and record the minutes

   • Have the resolution adopted by the majority applicable to the by-laws of the immovable (see section 1096 of the Civil Code of Quebec).
   • Record the decision in the register, attach the minutes and distribute the by-laws to all co-owners.

4. Communicate and support compliance

   • Send a clear reminder of the obligations, deadlines and remedies in the event of non-compliance.
   • Provide templates (certificate, declaration form) to simplify compliance.

Who pays, who carries out the work, and how to verify it

• Payment: replacement of a water heater in a private portion is the co-owner’s responsibility, unless the declaration of co-ownership provides otherwise.
• Work: give preference to a plumbing contractor holding the appropriate RBQ licence. This reduces the risk of defective work and facilitates insurance claims.
• Verification: the board of directors may request a copy of the invoice, a photo of the label (serial number/date), and confirmation of the required devices (pan, relief-valve discharge pipe and shut-off valve). In case of doubt, a visit with reasonable notice is permitted under the Civil Code (see section 1069 of the Civil Code of Quebec).

Minimum technical requirements to include in the by-laws

• A drain pan (with drainage to a floor drain, if available) beneath the tank.
• Proper connection of the safety/pressure relief-valve discharge pipe to a safe discharge point.
• Accessible, identified and operational shut-off valves.
• A leak detector with an alarm and, ideally, an automatic shut-off valve in higher-risk buildings.
• Compliant installation by a qualified contractor, a detailed invoice and proof of the contractor’s liability insurance.

These requirements are consistent with the safety objective of the by-laws of the immovable (see section 1060 of the Civil Code of Quebec) and help maintain the insurability of the co-ownership.

Non-compliance: what tools are available to the board?

• Notice and formal demand: send a written notice reminding the co-owner of the obligation and deadline. If the situation continues, a formal demand may follow.
• Access for inspection: the syndicate may access the private portion, with reasonable notice, to inspect or have work necessary to preserve the building carried out (see section 1069 of the Civil Code of Quebec).
• Penalties: if the by-laws provide for reasonable administrative penalties (e.g., monitoring fees), they must be adopted by the annual general meeting and applied in a non-abusive manner.
• Allocation of the consequences of a claim: depending on fault, negligence or non-compliance with the by-laws, the syndicate may claim certain costs not covered by insurance from the responsible co-owner, subject to the rules of the Civil Code and the policies in force. Obtain legal advice if necessary.

Tip: include the requirement in the co-owners’ annual certification form (including the water heater’s manufacturing date). Keep this proof in the syndicate’s register and mention the monitoring process in the board of directors’ annual report.

Alternatives and flexibility around the “10-year” rule

• Documented inspection: allow continued use beyond 10 years if a plumber certifies in writing that the condition is satisfactory (with no corrosion or leak) for a limited period (e.g., 12 to 24 months), with mandatory installation of a leak detector.
• Grace period: allow a transitional period to avoid mass replacements in the same year and smooth out the logistical impact.
• Specific equipment: distinguish standard tanks from indirect systems/boilers, which do not have the same risk profile.
• Group contracts: negotiate installation periods with licensed contractors for optimized pricing and logistics, while allowing the co-owner to choose the supplier.

These options make it possible to reflect technical realities while protecting the building and the common portions.

Frequently asked questions (FAQ)

Q1. My water heater is 11 years old but has never leaked. Do I have to replace it?
If your by-laws of the immovable require replacement after 10 years, you must comply, unless an exception applies (a plumber’s certificate or grace period). Check the declaration of co-ownership, the by-laws and the board of directors’ communications.

Q2. Can the syndicate enter my private portion to check the age of my water heater?
Yes, with reasonable notice and for legitimate reasons relating to the preservation and safety of the building (see section 1069 of the Civil Code of Quebec). In an emergency, access may be immediate.

Q3. Who pays if an old water heater causes water damage?
It depends on the policies and circumstances (fault, negligence and by-law provisions). The syndicate may sometimes recover certain costs from the responsible co-owner. Obtain legal advice and consult your insurer.
