ADU foundations and building slabs in Long Beach and Lakewood
A foundation is built to an engineer's plan and passes city inspection before any concrete arrives. We pour from approved plans, coordinate inspections, and leave the slab ready for your framer.

FAQ
Foundations and ADU Slabs questions
Do I need a permit for an ADU foundation?
Yes. An ADU is a dwelling, so the foundation needs plans and inspections from the city before and during construction.
Do I need a soil report?
Many cities or engineers require one for new living space, especially on expansive clay soils that are common in parts of the area. Your engineer will say what the plans need.
How long does a foundation take to cure before framing?
Framing can often start after several days, but follow your engineer and builder. Concrete reaches its design strength at about 28 days.
Can you pour a slab for a shed or AC unit?
Yes. Small slabs for sheds, AC units and equipment are quick jobs and usually don't need permits. [[CONFIRM: minimum job size]]
