Drainage and plumbing, Fairview
Drainage and Plumbing in Fairview Vancouver
Fairview is Vancouver’s strata belt. 12,321 of the 13,480 assessed properties here are strata, 91.4%, and almost 60% of them went up between 1976 and 1999. That is wood frame low rise on a hillside, not detached houses on clay tile.
So the first question on a Fairview call is usually not what is broken. It is whether the broken thing is yours or the strata’s. A camera answers that, and we camera before anybody quotes a number.
Built in the grey pipe decade
The 2026 City tax roll lists 13,480 assessed properties in Fairview. 4,239 of them went up in the 1980s, 31.4% of the whole neighbourhood, and another 2,869 in the 1990s. 1989 alone put up 740 units. Only 4.7% of Fairview predates 1965.
That matters because 5,213 Fairview properties, 38.7% of the stock, were built between 1985 and 1997. Poly-B went into Canadian buildings most commonly between 1978 and 1997 and came out of the Canadian plumbing code in 2005. It is usually grey, sometimes blue or white or red, and it is stamped PB or CSA-B. Insurers now surcharge it, set replacement deadlines, or decline water damage coverage outright.
Those are the same years as the leaky condo era. Around 45% of the 159,979 strata units built in BC between 1985 and 2000 turned out to have envelope leak problems, and Fairview Slopes buildings in particular were wood frame, tiered up the hillside toward Broadway, and mostly rainscreened later. If your building has already been through an envelope repair, the supply pipe behind the drywall is worth a look before the next one.
Go and read the pipe in your mechanical room instead of guessing from the build year. It takes a minute and it settles the argument.
The slope, and where the combined sewer still is
Fairview falls about 50 metres from West 16th Avenue down to the water over roughly 1.6 kilometres. The City’s contour data puts the shore strip at 2 to 22 metres and the West 15th to West 16th band at 42 to 54. Every lot here drains north. That is the whole reason the place is called Fairview Slopes.
The City’s own rainwater guidance is written for ground like this. Grade differences between adjacent lots create drainage problems, and the fix it names is a retaining wall with a drain tile system along the elevated areas. Surface water off driveways, parking pads and patios has to stay on your own property and must not be pushed onto the neighbour below.
The sewer under the street is mostly separated. Of 1,651 main segments inside Fairview, 816 are storm and 653 are sanitary. Only 182 are still combined, about 11%. But they are not spread evenly. 86 of those 182 sit in the West 12th to West 16th band, and 63 of those are between Granville and Oak, right around City Hall. North of West 4th there are only 21.
So if you are south of Broadway and things back up in heavy rain, a combined main is a live possibility and worth ruling in or out. Down on the flat by False Creek it usually is not, and the answer is normally something on your side of the line. There are 1,399 City catch basins inside the neighbourhood, and the ones on private ground are the owner’s to keep clear.

Fairview drainage and plumbing FAQ
Worth checking. 5,213 Fairview properties, 38.7% of the neighbourhood, were built between 1985 and 1997, and Poly-B went into Canadian buildings most commonly between 1978 and 1997. It is usually grey, though it also came in blue, white and red, and it is stamped PB or CSA-B. Read the pipe in the mechanical room rather than guessing from the build year.
Because of what it does when it fails. Insurers may add a surcharge to the premium, give you a deadline to have it replaced, or decline to offer water damage coverage at all. It was discontinued and removed from the Canadian plumbing code in 2005.
If more than one suite goes at once it is almost always the shared stack or the building lateral rather than anybody’s in-suite plumbing. We camera the shared line and show the strata council exactly where the fault is, which is usually what unblocks the decision as much as the pipe.
That pattern points at a combined sewer or at storm water getting into a line that should not have it. About 11% of Fairview’s mains are still combined, and 86 of those 182 segments sit between West 12th and West 16th, most of them between Granville and Oak. If you are south of Broadway it is worth ruling in or out.
Mostly not any more. Of 1,651 street main segments, 816 are storm and 653 are sanitary. Only 182 are combined and they are concentrated in the blocks around City Hall. North of West 4th Avenue there are just 21 of them.
We will not guess it. What we can tell you is that vitrified clay is still the single most common sewer material under Fairview streets at 556 segments, and clay cracks at the joint and lets roots in. Whatever your building lateral is, the camera reads it in one pass and you keep the footage.
Rainwater collected on pavement or concrete, so driveways, parking pads and patios, must not be directed to neighbouring properties. Where there is a grade difference between lots the City’s own suggested fix is a retaining wall with a drain tile system along the elevated areas. On a 50 metre slope that comes up a lot.
Possibly. Most new buildings in Vancouver have to provide on site rainwater management, and the required storage is set by the site area. Compliance is verified at the plumbing inspection stage, so it is better to have the answer before you get there than after.
The City’s own guidance is to contact 3-1-1 if your plumber finds the problem was caused by the City’s water or sewage system, so they can investigate. The City will also separate a private connection where there is a documented history of blockages they were responsible for, or where the owner has already replaced their portion and reports the City’s side is in poor condition.
All of Vancouver, plus Burnaby, New Westminster and the North Shore. Fairview runs from False Creek south to West 16th Avenue, Burrard on the west and Cambie on the east, so Kitsilano, Shaughnessy, South Granville, Mount Pleasant, Olympic Village and Cambie are all right next door.
