Construction Performance Guidelines
SETTLING, HEAVING OR SEPARATING OF LANDINGS OR STEPS
Stairs and landings supported by a foundation shall not heave, settle or separate from the main building more than 25 mm. Stairs and landings not requiring a foundation are not restricted from movement.
One-Year - Work and Materials. Two-Year - Ontario Building Code Health & Safety Violations. · Settlement and subsidence of the land around the building or along utility lines, other than subsidence beneath the footings of the building, is excluded from the statutory warranty. · Damage resulting from normal shrinkage of materials due to drying after construction is not covered by the statutory warranty.
Stairs, landings and decks not meeting the acceptable performance shall be repaired.
Concrete stairs having not more than two risers, and small wood stairs not attached to the building do not require foundations and are often affected by the settlement of supporting backfill; this is not covered by the statutory warranty.
