Fixed water suppression designed to the occupancy hazard. The single most consequential life-safety system in a retrofit budget. Mandatory in care occupancies with no size exemption, in high buildings, and pulled in by floor-area and occupancy limits for large assembly, mercantile and industrial floor plates.
The requirement basis is NBC 2020 Div. B, 3.2.5 (sprinkler requirements from 3.2.5.12) and the occupancy area limits of 3.2.2. Provincial editions adopt or amend the model code, so the clause numbering in force is the one published by the province — the edition named on this page is the one Securlor reads.
Costs are modelled as a national baseline per square foot (retrofit) — $5 to $12, with a mid-band of $8 — then scaled by the regional labour index. Annual inspection and monitoring runs $1,500 to $5,000.
Maintenance is the other half of ownership: annual inspection with quarterly visual checks, under NFC 2020 Div. B, 6.4, tested to NFPA 25, as adopted. A system that is installed but not inspected is a compliance failure waiting for an inspector to find it.
