Do I need a permit to replace my perimeter drain in Town of Sidney?

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.

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.

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

Perimeter drain permits in Sidney

Direct answer · reviewed 2026-09-29

Sidney's published rule is aimed at new construction rather than at a failed drain: a stormwater system designed by an engineer, and a covenant registered on your title. 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.
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 Every rule here was read on 29 September 2026; if you find one out of date, tell us and we will check it.

Sidney: new construction and a covenant on title: Applications for new construction, or projects that decrease site permeability, will likely require a storm water management system designed by a professional civil engineer, and a covenant must be registered on the property title before a building permit can be issued; This is aimed at new construction and hard-surfacing, not at replacing a failed drain · A covenant on title is a long-lived obligation and worth reading before you sign it; Town of Sidney · quoted · verified 2026-09-22

What the Town of Sidney publishes

These are the rules as the Town of Sidney states them, quoted rather than summarised.

Applications for new construction, or projects that decrease site permeability, will likely require a storm water management system designed by a professional civil engineer, and a covenant must be registered on the property title before a building permit can be issued

Four municipalities — Esquimalt, Colwood, Langford and Sidney — publish a plumbing permit but nothing about whether perimeter drainage itself is permitted work

A covenant on title is a long-lived obligation. If your project is large enough to trigger one, read it before you sign it.

On replacing an existing failed drain, the Town publishes nothing — ask.

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.
