What needs a permit in Barrie before you break ground.
Building a deck over 24 inches off grade: yes, building permit through the city.
Concrete patio at grade: no permit, but the locate call to Ontario One Call is still mandatory.
Retaining wall over 1 metre tall: yes, drawings stamped by an engineer plus a permit.
Fence over 7 feet: yes, sometimes β depends on the zone.
Pool surround paver patio: no permit on the deck itself, but the pool has its own approvals you've already done.
We pull whichever permits the job needs and roll the cost into the quote. If a contractor tells you 'permits aren't necessary' for a 1.2m wall, they're skipping the engineer's stamp. That's the line item that bites at resale.
