We pour slabs for sheds, shops, garages, additions and backyard cottages in Oakland. Soft ground near the estuary, clay in the hills and earthquake rules shape every design. Structural slabs are built to stamped plans under a City building permit.
We pour slabs for sheds, workshops, garages, carports, additions and backyard cottages. In Oakland the ground decides the design. Fill and soft soil near the estuary settle. Hill clay swells and shrinks. And the whole city is earthquake country, with the Hayward Fault running along the foot of the hills. A slab that will carry a building is structural work and is built to stamped plans.
For a building slab or foundation, the City of Oakland Planning and Building Department issues the permit and inspects the steel before any concrete is placed. Footing size, depth and reinforcement come from the plans and the California Building Code, which includes seismic requirements. Our part is to build exactly what the plans call for: forms, rebar, anchor bolts, hold-downs and the vapor barrier, all in the right place.
Simpler slabs, such as a shed pad or an equipment pad, still deserve a proper base. We remove topsoil, compact rock in layers and thicken the edges where loads sit. Tell us what will go on the slab, how heavy it is and whether a vehicle will ever drive onto it.
Slabs & foundations in Oakland: common questions
Do I need a permit for a slab in Oakland?
A slab for a building, addition, garage or dwelling unit needs a building permit with plans and inspections. A simple on-grade pad that carries no structure is usually exempt from a building permit under the state code, though zoning setbacks still apply. We check for your address.
Do you work from an engineer's plans?
Yes. For structural slabs and foundations we build to the engineer's or architect's drawings and call for the inspections the permit requires.
Does frost depth matter for footings here?
No. The ground in Oakland does not freeze to any depth. Footing depth here is set by the soil, the slope and the earthquake rules in the building code.
