- Basement Bathroom Rough-In in Ajax
Why it matters
Unpermitted plumbing tends to surface at the worst time: closing day, a claim, or the next contractor's walk-through, and the inspection itself catches mistakes while walls are still open.
The routine, in order
As a general guide, and always subject to the Town's current rules:
| Usually needs a permit | Usually does not |
|---|---|
| Adding a bathroom or a basement rough-in | Replacing a faucet |
| Moving or adding drains and vents | Swapping a toilet in the same spot |
| Installing a backwater valve | Fixing a leak in an existing pipe |
| Major repiping | Clearing a clogged drain |
- Describe the job to the Town of Ajax building department, or ask us to.
- Prepare simple drawings if asked.
- Phone for each inspection the permit card names, typically with pipes still exposed.
- File the signed-off card in the folder with the deed.
Mistakes to avoid
- Hanging drywall over pipe nobody from the Town has looked at.
- Taking a renovator's word that the paperwork exists.
- Going by whatever applied to the house next door in 2009.
Local tip Permit rules and fees change. Check the Town of Ajax's current requirements before you plan around anything on this page.
