Fast, Reliable General Contractor Across Los Altos Hills
Los Altos Hills is a different kind of town, and it needs a different kind of General Contractor. One-acre minimum lots, steep wooded parcels, private unimproved roads, and fire-hardening rules that don’t apply two miles away in Los Altos mean every permit, every truck, and every material choice has to be planned with local conditions in mind. We’re Milpitas Construction, led by Ken Stafford, and we’ve been running hillside, drainage, and WUI-compliant builds on 94022 properties long enough to know what the town’s reviewers actually look for. If you’re planning a remodel, addition, or ADU in Los Altos Hills, call (877) 752-4194 and we’ll walk your property before you spend a dollar on plans.
Why Milpitas Construction Is Los Altos Hills’s Preferred General Contractor Company
Homeowners here don’t hire a contractor to manage a simple interior refresh; they hire one to handle hillside grading, private-road flagging, defensible-space documentation, and a building department that reviews drainage impacts on downslope neighbors. That’s where our local reputation comes from. We show up with small equipment staged correctly on narrow shoulders, we pull permits that include the town’s hillside and drainage review from day one, and we specify ignition-resistant materials by name, including James Hardie siding and GAF roofing. Los Altos Hills customers keep calling us back because we never hand them a quote that omits a permit step the town will require later. Ken Stafford has built our process around the idea that a compliant quote should include everything: flaggers, erosion control, WUI-rated assemblies, and the inspection sign-offs that come with them.
Response time to Los Altos Hills matters more than it does in flat, city-grid neighborhoods. We schedule site walks around your availability and the town’s permit calendar, and we’ll tell you up front if your project triggers a hillside review, which most additions and nearly all ADUs on sloped lots do. Call (877) 752-4194 for an honest read on your property.

General Contractor Services in Los Altos Hills
Our Los Altos Hills CWS service means full-scope project ownership from the roofline to the kitchen counter, one contract and one point of contact. Whether you’re remodeling a mid-century rancher off Moody Road or adding an ADU on a private lane near O’Keefe Lane, the work has to hold up to hot, dry summers, seasonal wildfire risk, and winter rains on sloped ground. A home addition in Los Altos Hills typically runs $45,000 – $130,000, while ADU construction carries a $90,000 – $220,000 range depending on site access, foundation type, and WUI-rated assemblies.
Hillside Remodels and Additions
Remodeling in the hills is not the same as remodeling on a flat quarter-acre lot. Grading and drainage plans get scrutinized for downslope well and septic impacts, and that review adds time to the front end of every job. We plan for that from the first conversation, because writing the change order after the fact costs more than doing it right from the start.

ADU and Prefab Construction
Los Altos Hills lots often have room for an accessory dwelling unit, but the town’s septic coordination rules and WUI materials requirements can disqualify some standard prefab designs. We work with Abodu, Dvele, and Plant Prefab, and we understand which factory-built models clear 94022’s local review more smoothly than others. ADU construction here is a current specialty, not a pilot program.

Construction Company in Los Altos Hills
A Construction Company in Los Altos Hills has to handle what the town’s codes actually require, and those requirements start with storm and wind-load ratings for any addition or rebuild. Los Altos Hills sits in a wildland-urban interface exposure zone, so exterior assemblies need ignition-resistant materials and defensible-space documentation. Roof replacement here runs $8,000 – $20,000 and should include a rated underlayment that meets the town’s current code, not whatever the roofing supplier has in stock. Impact window installation, which matters on west-facing exposures above the valley floor, ranges $8,000 – $25,000.
Fire-Hardened Exteriors
We spec GAF and CertainTeed roofing, James Hardie siding, and PGT impact windows because those product lines carry the ratings the town’s reviewers and insurers want to see. A cheap quote that skips ignition-resistant decking or leaves old single-pane windows in place saves money on paper and creates a paper-trail problem at insurance renewal.
Driveways, Pavers, and Site Access
Paver driveway installation in Los Altos Hills averages $7,000 – $18,000, and we work with Belgard and other leading paver brands. Narrow private roads with unimproved shoulders often mean flaggers and small equipment, which we price into the initial quote instead of burying it in a change order after demolition starts.
Trusted Brands We Service in Los Altos Hills
We spec materials by name because Los Altos Hills homeowners deserve to know exactly what’s going into their home. Belgard pavers hold up to winter runoff on sloped driveways. Jerith and Bufftech aluminum and vinyl fencing handle the sun exposure without warping. ActiveYards gates work on the long private-road entrances common off Page Mill Road. Because we maintain active access to 50-plus brand-name product lines across every trade, we can match the right product to the right exposure and keep Los Altos Hills jobs moving without waiting on a big-box special order. We stock common parts locally for faster turnaround on warranty replacements.

AfterCommon General Contractor Problems We See in Los Altos Hills Homes
- Hillside drainage surprises after the draw schedule is set. A quote that skips the town’s hillside/drainage review looks cheaper until the permit stage, when downslope well and septic impacts surface. By then the owner has already committed to a build schedule built on a fiction.
- Missing fire-hardening documentation. Rebuilding without ignition-resistant materials and defensible-space records leaves the owner without the paper trail an insurer wants at claim or renewal time. Insurers in the 94022 corridor are paying attention.
- Narrow private-road access priced as an afterthought. Flaggers and small-equipment staging cost money, and homeowners are learning to ask whether that line item is in the first quote. If it is not, it will be in a change order.
- Old mid-century ranchers with termite damage hidden behind drywall. On a steep, wooded parcel off a private road in the 94022 hills, we rebuilt a termite-damaged subfloor and load-bearing wall in a mid-century rancher, specifying ignition-resistant siding and decking for the WUI exposure and running erosion-control measures before the winter rains. Every material substitution went through a written change order, and we walked the town inspector through the rough-in and inspection sign-off before closing up the walls.

FAQs About General Contractor in Los Altos Hills
Los Altos Hills additions and rebuilds must meet current California Building Code wind-load requirements for the Bay Area exposure, plus the town’s WUI ignition-resistant construction standards for exterior assemblies. That means rated roof underlayment, impact-rated windows on dominant exposures, and non-combustible or ignition-resistant siding and decking. We can show you exactly which products and ratings your specific parcel requires. Call (877) 752-4194 and we’ll walk the site with a list.
Documented fire-hardening gives your insurer a written record that the roof, siding, windows, and defensible space meet current WUI standards, which can support policy renewal and may influence premium pricing. Without that paper trail, the owner is left proving compliance after the fact. We document every rated assembly and inspectable milestone, then hand you the file. For a rebuild scope that includes full documentation, call (877) 752-4194.
Because Los Altos Hills requires a hillside/drainage review on most construction projects that Palo Alto and Los Altos do not apply to flat, city-sewer lots. The town reviews grading, drainage, and downslope impacts on neighbors’ wells and septic systems before approval, and that process adds weeks to the front end. We build that time into the schedule honestly, and we’ll tell you before you sign whether your project triggers the review. Call (877) 752-4194 for a straight answer.
A compliant Los Altos Hills quote includes the hillside/drainage review fee and timeline, flaggers and small-equipment staging for private-road access, WUI-rated material specifications by product name, and documented change-order procedures. A cheap quote leaves those out because it makes the number look better, then adds them as surprises mid-build. We write scopes that match the town’s actual requirements from day one. For a line-item quote on your project, call (877) 752-4194.
Yes. We stage small equipment and run flagger-managed traffic on private roads throughout the 94022 hills, including the narrowest unimproved lanes off Page Mill and Moody Road. We coordinate deliveries and refuse free access for downslope neighbors, which is part of getting the hillside review approved. If your road is tight, we’ll tell you up front what access management will cost, not after the first truck gets stuck. Call (877) 752-4194 to schedule a site walk.
