When a sprinkler permit is required

Renovations that alter, extend, relocate or disconnect a sprinkler system commonly require municipal permits and review under the Ontario Building Code and local bylaws. Confirm scope with Building Services before work begins; contact details and application instructions are on the City building permits page City of St. Catharines - Building Permits[1].

Preparing your application

  • Assemble contract drawings that show sprinkler modifications, scope of work and a plumbing/fire suppression schematic.
  • Provide a letter from the sprinkler contractor describing changes, system type and testing plans.
  • Be prepared to pay building permit and review fees; the City posts fee schedules on the Building Services page.

Some projects also require review by Fire Prevention; see Fire Services guidance for permit and inspection requirements City of St. Catharines - Fire Prevention[2].
