ACI 332
Residential Code Requirements for Structural Concrete and Commentary
Structural concrete in one- and two-family residential construction — footings, foundation walls, and related elements — at a scale appropriate to houses rather than commercial structures.
Who needs it
Residential foundation contractors, homebuilders, residential designers, and building officials reviewing house plans.
What the test involves
It provides code-language requirements for materials, proportioning, placement, and reinforcement of residential concrete, written so a builder does not need a full structural engineering analysis for routine conditions. It addresses the exposure and durability considerations that matter most in housing, particularly freezing climates and soils. It works alongside the residential building code rather than replacing it.
Common misconceptions
- It is not a simplified version of ACI 318 that can be used on commercial work. Its scope is genuinely limited to residential construction.
- Where a jurisdiction has adopted the residential building code's own concrete provisions, those govern, and ACI 332 may be an alternative path rather than the requirement.
- 'Residential' does not mean forgiving. Freeze-thaw exposure and soil conditions around a house are often harsher than those inside a commercial building.
