Slab foundation building in Anaheim CA - a solid base built to your plans

A reinforced concrete slab in Orange County usually costs about $8 to $14 per square foot, and that's the going rate around the county, not our price. A hillside lot, soft or swelling soil and a post-tensioned design tend to push a job toward the top, while a flat lot that's easy to reach keeps it lower. I'll give you a clear price for yours once I've walked it and measured.

Not always, because the city's Building Division can be asked to waive the soils report when a professional's opinion shows your site and planned construction don't need one. A granted waiver takes that report off the project, and the request also needs a drainage plan that Public Works reviews and approves, so we raise it early. A lot inside the area the City Engineer marks as hillside is different, since it needs a full soils and geology report and grading plans no matter the size.

A qualified design professional prepares them, and for most project types the city wants a California licensed architect or engineer. City staff leave the plans to your team, so hire your designer first. If your job needs one, I tell you early, and we build to those plans.

Yes, if the structure's footprint is greater than 1,200 square feet, because Public Works requires a grading permit and grading plans for those. On a smaller footprint, don't assume you're in the clear. Public Works is the office to ask, and I'll bring it up at the estimate.

Type your address into the state's EQ Zapp map and it shows whether the property sits in a mapped earthquake hazard zone. In a liquefaction zone, where shaken wet soil can lose its strength, the soil under a foundation has to be checked for stability, and the city says a geotechnical investigation may be required there. The County of Orange also notes expansive soil in some areas, so soil type is worth asking about on any Anaheim lot.

Usually it's the ground under it, like a base that was raked level instead of dug out and packed, water running toward the house and softening the soil, or clay that swells and shrinks with the seasons. That's why we spend the estimate on the soil and the grade, and why your plans may call for a post-tensioned slab.
