Quebec Condo Sewer Stack Camera Inspection: Who Pays?

In a divided co-ownership, sewer stacks and wastewater drain stacks are vital arteries. A well-planned camera inspection helps prevent backups, document the condition of the piping and guide the board of directors (board) on which work to prioritize. But who pays for the inspection and corrective work? Here is a practical guide for syndicates and co-owners in the Greater Montreal area.

What is a sewer stack camera inspection?

A camera inspection involves inserting a waterproof camera into a drain stack, a horizontal collector or a sewer line to film the inside of the pipe. The objective is to identify deterioration (corrosion, settlement), obstructions (grease, wipes, roots), defective connections and leaks. The video report and photos then serve as evidence when deciding on maintenance and work.

• Drain stacks and vertical collectors: often common portions, and therefore the responsibility of the syndicate.
• Fixture connections (toilet, sink) up to the connection point at the stack: generally private portions, to be confirmed in the declaration of co-ownership.
• The building’s main sewer line to the public right-of-way: frequently common; the declaration of co-ownership specifies the limits.

In Quebec, every plumbing contractor must hold the appropriate RBQ licence, especially if the intervention goes beyond a simple inspection and involves repairs. Consult the Regie du batiment du Quebec for licensing and compliance requirements.

• RBQ reference: plumbing and drainage.

When should you schedule a camera inspection?

Proactively scheduling an inspection helps prevent costly damage and unexpected condo fees. Aim for a frequency aligned with your building’s age, materials and history.

• Buildings 25 years and older (cast iron, steel): every 3 to 5 years, or after a backup.
• Recent buildings (PVC/ABS): every 5 to 7 years, unless there are warning signs.
• After a loss or major work: to validate the restoration and document the before-and-after condition.

Typical triggers:

• Recurring backups on the same floor or in nearby stacks.
• Sewer odours, unusual noises or slow drainage.
• Water infiltration on the ceiling around a wet stack or brownish stains.

Adding this task to your maintenance logbook and to the component maintenance and wear study (EUC) supports realistic budget planning. Since the obligations relating to the maintenance logbook came into force, several syndicates have included recurring camera inspections in their preventive maintenance program.

Who pays? Cost-allocation principles in co-ownership

The key is found in the declaration of co-ownership and the rules of the Civil Code of Quebec (C.c.Q.). In principle, expenses relating to common portions are borne by the syndicate and paid through common expenses (see section 1064 C.c.Q.), while repairs to private portions are the responsibility of the co-owner concerned. There may be exceptions if the declaration of co-ownership classifies a portion of the piping as a common portion for restricted use.

• Useful LégisQuébec references: section 1064 C.c.Q. and the C.c.Q. (sections 1038 and following) section on divided co-ownership.

Here are common situations and the usual allocation of costs, subject to your declaration of co-ownership and the specific facts.

When the event constitutes a loss, the syndicate’s and co-owners’ insurance coverage applies according to the respective policies and the provisions of the Civil Code of Quebec. Avoid assumptions: support any recharge with a video report, photos and findings from a plumbing professional.

• Co-ownership best practices: RGCQ (resources and training).

Recommended procedure for the board

A structured approach limits disputes and facilitates communication with co-owners.

1. Resolution and mandate

   • Adopt a board resolution specifying the purpose, the stacks concerned, the contractor selected and the access arrangements.
   • Attach deliverable requirements to the mandate: HD video, georeferenced recordings, a time-stamped report with reference points (metres) and recommendations.

2. Notice and access

   • Notify co-owners and occupants in advance, with time windows and instructions (clear access areas, protect finishes).
   • Manage access keys and ensure that a syndicate representative is present on site.

3. Execution and safety

   • Check the protective measures (tarps, recovery bins, disinfection after the intervention).
   • Confirm that the contractor holds an RBQ licence and adequate liability insurance.

4. Report, decision and follow-up

   • File the report in the syndicate’s register and the maintenance logbook/EUC; archive the source files.
   • Prioritize corrective work, estimate its scope in broad terms and determine whether it is routine maintenance or a project eligible for the contingency fund.
   • Record the decisions and budgets in the minutes of the next board meeting and, if necessary, inform the annual general meeting.

Frequency, maintenance logbook and budget: how to plan

– Maintenance logbook/EUC: record the camera inspection with a frequency and a trigger (after a loss/backup). Attach the technical sheet for the stacks (materials, diameter, year of installation).
– Annual budget: the inspection is generally routine maintenance, so include it in the operating budget. Also set aside a margin for corrective cleaning if the inspection reveals an obstruction.
– Major projects: if the inspection concludes that the stacks must be replaced, this will normally be a foreseeable capital project financed through the contingency fund. The contingency fund study and the EUC should then be updated to reflect the schedule and estimated cost.

Frequently asked questions (FAQ)

Q1. Is a camera inspection of sewer stacks mandatory?
There is no general obligation imposing a specific frequency. However, the board of directors must maintain the common portions with prudence and diligence. A camera is strongly recommended when signs of deterioration or backup appear, and to document the condition of the stacks in the maintenance logbook.

Q2. Can the inspection be paid for with the contingency fund?
Usually not, since it is routine maintenance. The contingency fund is intended for major repairs and replacements of common portions. If the inspection is part of an approved stack rehabilitation project (major work), its costs may be included in that project. Refer to your declaration of co-ownership and, if necessary, consult an adviser.

Q3. Who keeps the videos and for how long?
The syndicate should keep the reports and source files in its register, in accordance with its document policy. Keep them at least until the next scheduled inspection and until any dispute or potential claim has ended. Ensure secure backup and access control.
