Does perimeter drain work need a permit in Langford, and who is allowed to do it?
Perimeter drain permits in Langford
Direct answer · reviewed 2026-09-29
Langford publishes one broad trigger — any installation, alteration or repair of a plumbing system needs a permit — and nothing that says whether a perimeter drain is one. Nothing published here requires the drain to be inspected before it is buried, which means the only person who will ever see the work is the person doing it. What the municipality requires for the connection at the street is not published, so confirm it before you accept a quote that includes one.
Conditions and exceptions
- This reports what the municipality publishes, read from its own page, form or bylaw. It is not legal advice and it does not replace a call to the municipal office.
- Published-nothing is not the same as no rule. It means the answer is not written down anywhere public, and a homeowner who assumes the neighbouring municipality's rule is guessing.
- Three of the thirteen municipalities do inspect before backfill. That yours does not is a reason to ask the contractor for photographs of the open trench.
- Bylaws are amended. Every rule here was read on 29 September 2026; if you find one out of date, tell us and we will check it.

What the City of Langford publishes
These are the rules as the City of Langford states them, quoted rather than summarised.

Langford has grown faster than any municipality here, so a great many of its houses are new enough to still have their original, working drains.
What to settle before you accept a quote
Because nothing is published, the quote is where the permit question gets decided — and a contractor who cannot say which rule they are relying on has not decided it either.
- 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.
Questions homeowners ask
- Do I need a permit to replace my perimeter drain in City of Langford?
- Nothing published answers that directly. The general plumbing trigger may or may not be read to include a foundation drain, and only the municipality can say. Call and ask the three questions above; it is a short call.
- 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.
- Nobody inspects it here. What can I do instead?
- Ask for photographs of the open trench before it is filled: the pipe in place, the stone over it, and the wall. A contractor who does good work will not mind, and one who minds has told you something.
