Fast, Reliable General Contractor Across Los Altos Hills
Finding a General Contractor in Los Altos Hills means dealing with a town that has some of the strictest hillside and lot-coverage rules in Santa Clara County. Most projects here, even a deck or driveway replacement, must clear design review before a permit gets issued. Viceroy Construction handles that planning layer as part of the scope, not as an afterthought. We work across the 94022 zip code, from the winding roads off Page Mill to the larger parcels near Purissima Road. Call (877) 358-6557 to schedule a free estimate.
Why Viceroy Construction Is Los Altos Hills’s Preferred General Contractor Company
Neil Drummond leads our Los Altos Hills projects, and he treats the town’s development cap as the starting point of every quote, not a surprise that shows up later. Our clients here tell us the same thing: they tried getting bids from contractors who did not understand the 25% lot-coverage rule, and the numbers changed once the planning department got involved. We do not work that way. We run the coverage calculation during the estimating phase so the price you approve is the price tied to a permit-ready scope.
Response time to Los Altos Hills matters because hillside builds do not wait well. A delayed structural inspection in winter, when saturated soil starts moving, can turn a small retaining wall job into a slope stabilization project. We schedule site visits around the town’s inspection calendar and keep one point of contact on every job, from first design review submission to final sign-off. That continuity is the difference between a project that finishes and one that drags through three redesigns.
Styles & brands we work with
General Contractor Services in Los Altos Hills
General Contractor Services in Los Altos Hills cover interior remodels, exterior renovations, roofing, hardscaping, and ADU builds, all under one contract. A homeowner here is often juggling an aging 1970s house, a septic system that needs verification, and a lot that is already close to its development cap. We manage the full scope: demolition, framing, trade coordination, brand-specific material installation, and the permit closeout. A typical whole-home remodel in Los Altos Hills runs $14,000 to $45,000 for kitchens and $9,000 to $28,000 for bathrooms, while additions start around $45,000 and can reach $130,000 depending on structural work and foundation engineering.
Design Review and Permit Management
The town’s design review process applies to nearly any visible change, including exterior paint color shifts, new decks, and driveway replacements. We prepare the stamped plans, run the lot-coverage math, and submit the application. If a prior owner added square footage without permits, which happens frequently in Los Altos Hills, we document it and bring the project into compliance before new work begins.
Interior and Exterior Remodel Scope
We coordinate the full trade stack: cabinetry from KraftMaid or Wellborn, countertops from Cambria or Silestone, plumbing fixtures from Kohler or Grohe, and roofing systems from GAF or CertainTeed. That means the homeowner never has to call a separate cabinet supplier or roofing crew. One contractor, one schedule, one contract.

Construction Company in Los Altos Hills
As a Construction Company working in Los Altos Hills, we take accountability for the parts of the job most contractors hand off: the engineering review, the septic and well verification, and the final inspection documentation. Home additions here cost $45,000 to $130,000, but the real variable is whether the property already has a perc test on file and whether the well produces enough flow for the added square footage. We pull those records early. A garage conversion runs $30,000 to $80,000, and an ADU construction project lands between $90,000 and $220,000 based on the unit type, site access, and foundation requirements.
Storm Compliance and Wind-Load Requirements
Los Altos Hills sits in the rain shadow of the Santa Cruz Mountains, which sounds mild until a winter storm drives heavy rain into hillside soil. The town enforces wind-load requirements that most flatland contractors never see. Decks, roof replacements, and any structural change must meet those ratings, and the inspector will check the connector hardware, not just the framing. We use Simpson Strong-Tie connectors and roofing systems from GAF and CertainTeed that are rated for the local exposure. If a cheap quote skips the rated connectors, the inspection fails, and the homeowner pays twice.
Foundation, Drainage, and Slope Work
Hillside lots mean drainage is not a suggestion. We install retaining walls, French drains, and surface grading that move water away from foundations before it saturates the slope. On a hillside property off Elena Road, we replaced an aging redwood deck that had been built without permits. Our crew had to first verify the load-bearing capacity of the existing framing, then submit stamped engineering plans to the town for design review before we could pull permits. After passing inspection sign-off, we installed a new deck with Simpson Strong-Tie connectors rated for the local wind load, a detail the homeowner’s insurance adjuster specifically requested when we documented the upgrade for their policy.
Trusted Brands We Service in Los Altos Hills
We stock and install products that meet Los Altos Hills’ specific code requirements. Roofing systems from GAF and CertainTeed carry the wind ratings inspectors look for. Plumbing fixtures from Grohe and Sterling are available for immediate delivery, so a bathroom remodel does not stall waiting on a faucet. For exterior work, James Hardie siding holds up to the dry summers and occasional downpours better than original redwood from the 1960s. When a homeowner wants Cambria quartz or Caesarstone, we handle the template, fabrication, and install through our national brand network. No running around to showrooms across the Bay Area.

AfterCommon General Contractor Problems We See in Los Altos Hills Homes
- Skipping the 25% lot-coverage calculation: A homeowner approves a scope, then the planning department flags it because the total development exceeds the cap. We run that math before the bid, not after the red tag.
- Non-rated connectors that fail wind-load inspection: The Santa Cruz Mountains rain shadow still sees real wind events. Cheap ties and hangers fail the inspection, and an insurance adjuster may deny coverage later if the hardware was not documented.
- Unpermitted additions from prior owners: Many 1950s to 1980s homes in Los Altos Hills have rooms or decks that were never permitted. We verify the record, bring the work into compliance, and avoid the buyer-seller liability trap down the road.
- Private well and septic delays: New construction or an addition requires a perc test and well-flow verification before permits get issued. Contractors unfamiliar with semirural lots forget this, and the project stalls for weeks. We pull records during estimating.

FAQs About General Contractor in Los Altos Hills
The town enforces wind-load requirements based on the Santa Cruz Mountains exposure, which means decks and roof replacements must use rated connectors and fasteners, not standard hardware. We use Simpson Strong-Tie connectors and GAF or CertainTeed roofing systems that meet the local wind rating. Call (877) 358-6557 so we can check your property’s exposure rating in the permit history.
Los Altos Hills caps total development at 25% of the lot size, including the house, decks, driveways, and some accessory structures. If your addition pushes the total over that line, the town will deny the permit until the scope shrinks or a variance gets approved. We run the calculation before pricing the job so you do not pay for plans that cannot get approved.
Yes, if the addition changes the sewage load, most properties on private septic require a perc test and well-flow verification before the permit moves forward. We pull those records during the bidding phase and coordinate the testing with local engineers. That keeps the schedule from stalling mid-permit.
A compliant quote includes the design review submission, stamped engineering plans, lot-coverage math, rated connectors, and the final inspection closeout. A cheap quote typically covers labor and materials only, leaving the permit, engineering, and compliance costs as change orders later. We write fixed-price quotes with the full scope, so the number does not move unless you change the project.
When a homeowner documents that a deck or roof was replaced with wind-rated materials and proper connectors, some insurers will adjust the premium or confirm coverage that might otherwise be questioned after a storm. We provide the closeout paperwork and photos that show the rated hardware installed. The adjuster on the Elena Road deck replacement specifically requested that documentation before updating the policy.
