Fast, Reliable General Contractor Across Los Altos Hills
Finding a general contractor who understands Los Altos Hills means finding someone who gets what this town actually is: one-acre-plus lots, private lanes, hillside grading, and a permitting process that runs through Santa Clara County, not the Town. We’re San Mateo Construction, and we’ve worked these parcels long enough to know that the logistics of the job often matter more than the framing. From long unpaved driveways off Robleda Road to ridge lots with scenic-corridor review, we scope every project around access, drainage, and design review before we ever quote. If you’re planning a custom rebuild, a major addition, or a detached ADU in Los Altos Hills, call (855) 901-7266 for a free estimate.
Why San Mateo Construction Is Los Altos Hills’s Preferred General Contractor Company
Homeowners in Los Altos Hills don’t have tract housing or cookie-cutter lots. They have mid-century ranchers that have outlived their septic systems, hillside parcels that need regrading before anything else happens, and private roads that concrete trucks sometimes can’t navigate. Our team has worked those conditions long enough to plan for them up front. We carry strong local references from Los Altos Hills customers, and the feedback we hear most is that we show up with a schedule that accounts for the Town’s scenic-corridor review instead of pretending it won’t affect the timeline.
Response time matters here too. When you’re on a hillside lot with winter rain coming and an exposed cut, a contractor who takes two weeks to return a call isn’t helpful. We route Los Altos Hills inquiries directly to a project lead who knows the terrain. Noel Carrington, our owner, has walked plenty of these sites himself before the first drawing gets revised.
What builds trust in this town is honesty about permitting. We tell you up front whether Santa Clara County issues your building permit and whether the Town’s design review will layer on top. Most homeowners we meet have heard stories about projects that stalled for months because nobody flagged the scenic-corridor process. We’d rather explain it before you sign than apologize after.
Styles & brands we work with
Licensed General Contractor in Los Altos Hills
A Licensed General Contractor in Los Altos Hills handles the full scope of a project under a single contract: structural work, grading and drainage, exterior systems, and interior finishes. State licensing means the contractor is bonded and follows California building codes, but in this town it also means knowing which permits come from Santa Clara County and which reviews come from the Town. On a typical Los Altos Hills rebuild, we’re coordinating county inspectors, Town design reviewers, and the trades all at once. Home additions run $45,000 to $130,000, and a detached ADU typically lands between $90,000 and $220,000 depending on access, foundation, and utility extensions.
County Permits and Town Review
Los Altos Hills operates under a dual-permit system that catches people off guard. Building permits for many parcels come from Santa Clara County, while the Town’s scenic-corridor and hillside ordinances add design review on top. That means a ridge lot rebuild might take months to get through both layers before we can break ground. We map that timeline for you in writing.
Septic, Wells, and Setbacks
Larger lots in Los Altos Hills often run on septic and private wells rather than municipal sewer and water. Any addition, ADU, or garage conversion has to work around those setbacks. We coordinate the soil testing, leach field design, and well clearance as part of the scope, not as an afterthought.
Residential General Contractor in Los Altos Hills
A Residential General Contractor in Los Altos Hills manages home construction and remodeling projects from roofline to foundation, with one accountable team instead of a stack of separate subcontracts. For homeowners in Los Altos Hills, that single-point responsibility matters because the work often involves hillside foundations, retaining walls, and long private driveways that complicate every trade from excavation to drywall delivery. A garage conversion runs $30,000 to $80,000, while full kitchen and bath remodels fall into the ranges we’ve outlined below. The value is in having one company responsible for the grading, the framing, the finishes, and the final inspection sign-off.
Whole-Home Renovation on Hillside Lots
Remodeling a Los Altos Hills home usually means working with an existing structure that sits on a slope or on a foundation that predates current seismic code. We assess the foundation, drainage, and retaining conditions before we quote interior work. That order of operations prevents the expensive surprise of discovering a drainage problem after the new kitchen is in.
Brand Selection Across Every System
Because we’re a general contractor rather than a single-trade remodeler, we can help you choose materials across the entire project. Cabinet lines from KraftMaid or Wellborn. Countertops from Cambria, Silestone, or Caesarstone. Plumbing fixtures from Kohler, Grohe, Toto, or Moen. Exterior work with GAF or Owens Corning roofing, PGT windows, and James Hardie siding. We help you match material tiers to your budget without handing you a catalog and walking away.
Trusted Brands We Service in Los Altos Hills
We work with more than 50 name-brand suppliers, which means your Los Altos Hills project isn’t limited to whatever the local supply house has on the shelf. For roofing, we install GAF, CertainTeed, and Owens Corning systems. For windows and doors, PGT and Therma-Tru. For exterior siding, James Hardie and Boral. We also keep relationships with CGI and Tamko for specialty exterior applications where those products fit the site conditions. The advantage for a Los Altos Hills homeowner is straightforward: you choose from a curated set of vetted brands, and we handle the procurement, delivery, and installation.

AfterCommon General Contractor Problems We See in Los Altos Hills Homes
- Permit jurisdiction confusion: Homeowners assume the Town of Los Altos Hills issues every permit. On unincorporated parcels, Santa Clara County actually handles the building permit, while the Town layers scenic-corridor and hillside review on top. Getting this wrong causes delays and can leave work unpermitted.
- Private road and driveway access: Narrow lanes and long unpaved approaches along roads like Robleda Road often mean a concrete truck or excavator can’t reach the site. We scout access before quoting so you’re not hit with a change order for smaller equipment or staged deliveries.
- Grading and drainage failures: Hillside lots shed water fast in winter. If the drainage plan isn’t designed for the slope, you get erosion, slope instability, and failed inspections. We include a drainage scope in every hillside quote.
- Septic and well setback oversights: Many Los Altos Hills properties aren’t on municipal sewer. An addition or ADU that ignores septic setbacks will stall at the county approval stage. We verify those requirements during the estimating phase, not after you’ve paid for drawings.

FAQs About General Contractor in Los Altos Hills
For many parcels in Los Altos Hills, the building permit comes from Santa Clara County, while the Town’s scenic-corridor and hillside ordinances add design review on top. The answer depends on your specific parcel and project scope. We verify the permit path during the estimate so you don’t end up with unpermitted work or a stalled approval. Call (855) 901-7266 and we’ll check your address before you commit to anything.
We include septic and well verification as part of the pre-construction scope for any addition, ADU, or garage conversion in Los Altos Hills. That means soil testing, leach field location, and well clearance get checked before drawings are finalized. Failing a county septic inspection after framing is done is the expensive way to learn the setback rules. We’d rather you learn them in the planning phase. Call us for an exact quote on your lot.
Expect that standard concrete trucks and excavators may not reach your site if you’re on a narrow private lane or a long unpaved approach. We scout the access route before quoting and plan for smaller loads, staged deliveries, or equipment that can safely navigate the approach. That prevents a change order mid-project because the truck couldn’t make the turn. For a detailed site assessment, call (855) 901-7266.
The scenic-corridor review can add several months to a Los Altos Hills project before we break ground. The Town reviews the design against its hillside and ridgeline rules, and that process runs parallel to or after the county building permit. We build that review time into your schedule up front so you’re not surprised when approval takes longer than a flat-lot city like Mountain View. We can walk you through the expected timeline for your specific parcel.
Building a detached ADU or shop in Los Altos Hills starts with verifying county permit requirements, septic and well setbacks, and Town design review on your parcel. We then design the structure around those constraints, secure the permits, and manage the build. Detached ADUs here typically run $90,000 to $220,000 depending on access and utility work. Call (855) 901-7266 to schedule a free estimate and we’ll map the process for your lot.
Los Altos Hills is a unique place to build. The combination of county permitting, private-road access, wildland-urban interface rules, and scenic-corridor review shapes every decision on the job. We’ve rebuilt mid-century ranchers off Robleda Road, regraded hillside lots for proper drainage, coordinated crane staging on narrow driveways, and revised draw schedules when the Town’s review added time. That’s the work we do here.
