Do I need a permit to replace my perimeter drain in District of Highlands?

For the drain itself, see what the municipality publishes above. For the connection to the municipal system, the answer is more often yes than no, and that is the part worth confirming in writing.

My contractor says no permit is needed. Is that a red flag?

Not on its own. In several municipalities the trench beside your house genuinely is not named as permitted work while the connection to the storm system is. It becomes a red flag when they cannot say which rule they are relying on.

What does the pre-backfill inspection actually get me?

An independent look at the parts you can never see again: the pipe, how much clean stone is over it, and the dampproofing on the wall. Ask for the result in writing and keep it — a buyer's inspector will care about it in ten years.

Does perimeter drain work need a permit in Highlands, and who is allowed to do it?

Perimeter drain permits in Highlands

Direct answer · reviewed 2026-09-29

Highlands publishes one rule about drainage and it happens to be the most valuable one: the perimeter drain tiles and the dampproofing may not be covered up until a Building Official has accepted them. Ask for that inspection and ask for the result: it is the only moment an independent person sees the pipe, the stone and the dampproofing, and it costs you nothing. On the connection at the street: a plumbing permit is required for installing or altering plumbing systems or sewers; nothing further is published about the storm connection.

What the District of Highlands publishes

These are the rules as the District of Highlands states them, quoted rather than summarised.

Three publish the rule in their own bylaws: Victoria, Highlands and North Saanich

Highlands lots are large, rocky and often on septic — the destination for the drain water is more likely to be a ditch or a dry well than a storm sewer, which brings the 5 m rule into play.

What to settle before you accept a quote

A quote that is silent on the permit is a quote with an open question in it. These are the three that close it.

Does replacing perimeter drain tile need a plumbing or a building permit here?
Does the connection to the storm system need a separate permit, and who is allowed to make it?
Is there an inspection before the trench is backfilled, and will I get the result?

What does not change between municipalities

The Building Code is provincial, so the pipe, the stone, the depth and the legal destinations for the water are identical in all thirteen places. 100 mm (4 inches) At least 150 mm of crushed stone or other coarse clean granular material, with no more than 10% passing a 4 mm sieve To a sewer, a drainage ditch or a dry well

So is the honest limit on what anyone can tell you: until a camera has been down the pipe, nobody knows whether it is blocked, broken or fine — and that includes us.
