Engineered, code-compliant foundations for new homes, ADUs, additions and buildings in Hayward — poured to your soil report and your build schedule, not a generic template.
Hayward building departments review foundation plans against the site conditions your specific parcel actually has — a mix of bay flatland and East Bay hillside conditions depending on exactly where your lot sits, which is why we confirm soil and grading conditions parcel by parcel rather than assuming one condition citywide. Most of the projects we take on in Hayward sit on a wide range of lot types, from flatland single-family parcels to hillside properties with real grade change, 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 Hayward 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 Hayward — 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 Hayward lots.
New footings and foundation extensions for room and second-story additions in Hayward, tied into your existing foundation correctly.
Both foundation types, built to spec for Hayward'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 Hayward 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.
East Bay soil and terrain vary block by block — we confirm your parcel's actual conditions from your soil report instead of assuming they match the neighborhood.
We plan pours around your framer's start date, not the other way around.
Based in the Bay Area, working throughout Santa Clara, San Mateo, Alameda and Contra Costa counties.
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 Hayward 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.
Hayward is an incorporated city with its own building department, so permits for your foundation project go through the city rather than Alameda County directly. We coordinate the inspection process with whichever jurisdiction actually governs your parcel.
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.
Tell us what you're building — a new home, an ADU, an addition — and we'll get back to you with next steps, usually within one business day.
