Engineered, code-compliant foundations for new homes, ADUs, additions and buildings in Redwood City — poured to your soil report and your build schedule, not a generic template.
Redwood City building departments review foundation plans against the site conditions your specific parcel actually has — a mix of bay mud and clay soils and, in the flatter parts of the city, a higher water table than you'll find further inland — both of which affect whether a slab-on-grade or raised foundation is the right call. Most of the projects we take on in Redwood City sit on established single-family lots, many with older homes now going through ADU and addition projects, and a foundation designed without accounting for that tends to draw corrections or, worse, perform poorly once it's in the ground. We start every Redwood City project by confirming your soil report, your structural engineer's plans and your site's actual conditions, then build to that — not a template adjusted after the fact.
Full foundation construction for ground-up custom homes in Redwood City — excavation, forming, rebar and pour, built to your engineer's stamped plans.
Slab-on-grade and raised foundations sized and engineered for detached, attached and garage-conversion ADUs on Redwood City lots.
New footings and foundation extensions for room and second-story additions in Redwood City, tied into your existing foundation correctly.
Both foundation types, built to spec for Redwood City's soil and drainage conditions — a straightforward slab where it fits, a raised foundation where it's needed.
We review your approved plans, structural engineering and soil report against your specific Redwood City parcel before anything is dug.
Excavation, forming and rebar placement built to the engineered spec — footings, stem walls or slab, sized and reinforced correctly.
Concrete poured, finished and cured on schedule, with documentation your inspector and general contractor both need.
We coordinate the foundation inspection and hand off a foundation that's ready for your framer.
Two decades pouring foundations across the Bay Area, not a generic national template.
Full California contractor's license and insurance coverage — ask to see it.
We check groundwater and soil conditions before recommending a foundation type, since bay mud and a high water table can rule out a straightforward slab on some Peninsula lots.
We plan pours around your framer's start date, not the other way around.
Con base en el Área de la Bahía, trabajamos en los condados de Santa Clara, San Mateo, Alameda y Contra Costa.
In almost all cases, yes — foundation design for new construction, additions and ADUs typically requires a licensed structural engineer's stamped plans before a building department will permit it. We build to those stamped plans; if you don't have an engineer yet, we can point you to ones we work with regularly.
It depends on project size and foundation type — a straightforward ADU slab in Redwood City moves much faster than a full custom home foundation with extensive grading. We'll give you a realistic timeline once we've reviewed your specific plans and site.
Most single-family lots qualify for at least one ADU under state law, subject to local setback, height and lot-coverage rules that vary by city and zoning district. We confirm what your parcel supports as part of the foundation design process, working alongside your ADU plans.
Both. Some clients come to us directly, often before they've hired a general contractor; others are referred by a GC or architect who wants a foundation sub they can hand a stamped plan set to and trust.
It can. Parts of Redwood City have a higher water table and softer bay mud soils than inland cities, which sometimes pushes the design toward a raised foundation or additional drainage measures instead of a simple slab. We confirm this against your soil report and site conditions before finalizing a design, not after we've started digging.
New construction is our primary focus, but we do take on foundation repair and seismic retrofit work for existing homes as a secondary service — see our Foundation Repair & Retrofit page for details.
