Fast, Reliable General Contractor Across Los Altos
Most Los Altos home additions and ADUs run into trouble before a single wall goes up. The city caps residential lot coverage at 45% of floor-area ratio, and homes built in the 1950s and 60s often already sit past 40% before you add a square foot. That’s why a general contractor in Los Altos has to verify lot coverage against the city’s zoning code first, not after you’ve signed a design and started paying for drawings. Sawyer Remodeling handles that check on every addition, kitchen remodel, and ADU project in Los Altos, CA. Call (254) 272-5876 and we’ll walk your lot’s numbers before you commit to anything.
Why Sawyer Remodeling Is Los Altos’s Preferred General Contractor Company

Luca Romano leads our Los Altos projects, and his first question on any addition or remodel is about the lot, not the finishes. That’s the kind of local knowledge that keeps a Los Altos project from stalling at the permit counter. We’ve pulled permits for work on homes off San Antonio Road, near Foothill Expressway, and up in the hills above downtown, and the answer always starts with what the city will actually approve.
Everything we quote is a written price, not a ballpark. When you work with Sawyer Remodeling, you get General Contractor services under The Relay Visibility Guarantee: a live arrival time, photo updates before and after each phase, and a line-item invoice you can approve from your phone. If it’s not done right, our 365-Day Done Right Promise covers the fix in writing. No change orders hiding in the drywall, no allowances that drift into five figures without your sign-off.
Styles & brands we work with







Hire a General Contractor in Los Altos
Hire a General Contractor in Los Altos when the project needs a permit, a structural change, or coordination across three or more trades. A kitchen remodel that moves plumbing, rewires circuits, and pulls a gas line cannot legally proceed as a handyman job in Los Altos, CA, and the city’s inspectors will catch it at rough-in. Typical kitchen remodels in Los Altos run $14,000 to $45,000 depending on cabinet grade, countertop selection, and whether walls move. Bathroom remodels fall between $9,000 and $28,000.
Permit and Inspection Sequencing
Los Altos building inspectors require a pre-drywall sign-off on bathroom and kitchen rough-in. That means plumbing, electrical, and framing get checked before insulation and drywall close the walls. Skip that step and you’re tearing out finished work to re-inspect. We schedule every inspection as part of the project calendar, not as an afterthought.
Draw Schedules and Written Allowances
We write allowance schedules for cabinets, counters, tile, and fixtures before work begins. You choose the Cambria slab or the Kohler fixture against that number, and the invoice matches. If you upgrade mid-project, the change order lands in writing before the purchase order is placed. Nothing drifts.
General Contractor Services in Los Altos
General Contractor Services in Los Altos mean full-scope remodeling and construction, from a 1960s ranch addition to a detached ADU in the rear yard. Home additions in Los Altos, CA start around $45,000 for a simple bump-out and reach $130,000 for a large two-story addition with a bathroom rough-in. ADU construction ranges from $90,000 to $220,000, with the biggest drivers being foundation type, utility trenching, and whether the ADU shares a wall with the existing house.
Whole Home and Kitchen Remodeling
A whole-home remodel in Los Altos often means opening walls in a house built before Title 24 energy codes existed, which means the electrical panel, insulation, and windows may all need upgrades to pass inspection. Kitchen remodels in Los Altos typically range $14,000 to $45,000. A small kitchen remodel on a galley footprint with stock KraftMaid cabinets can come in around $9,000 to $20,000.

Bathroom and Addition Work
Bathroom remodels in Los Altos fall between $9,000 and $28,000, with walk-in shower installations from $4,500 to $12,000. Room additions and ADU construction in Los Altos have to respect not just the 45% floor-area ratio but also single-story height limits across much of R-1 zoning. We check both before the first drawing is done.

Trusted Brands We Service in Los Altos
We install and manage material partners that homeowners in Los Altos actually ask for by name: Cambria and Silestone countertops, Wellborn and KraftMaid cabinetry, Kohler and Toto fixtures, GAF roofing, and James Hardie siding. For ADU and addition work, we’ve worked with prefab and panelized systems from Cover and Abodu when the timeline matters more than a fully custom frame. If you’ve already picked a Sakrete or Dvele product, we’ll incorporate it into the written scope. Sourcing from known brands means the manufacturer stands behind the product while we stand behind the install, one year in writing.

AfterCommon General Contractor Problems We See in Los Altos Homes
- The floor-area ratio trap. Los Altos enforces a 45% maximum lot coverage, and homes built in the 1950s and 60s often sit at 40% or more before any addition. A contractor who bids from a napkin sketch without pulling the survey is selling a redesign later. We verify lot coverage first, every time.
- Allowances treated as final numbers. Los Altos clients regularly upgrade to Cambria or Silestone once they see the slab in person. Without a written allowance schedule, each upgrade becomes a change order that adds cost and weeks. We write the allowance number into the contract before work starts.
- Skipped pre-drywall inspections. Los Altos inspectors require rough-in sign-off on kitchens and bathrooms before insulation goes in. Closing walls early means opening them again. We build the inspection sequence into the calendar and never let a trade close a wall without the sign-off.
- Single-story height limit conflicts. Many R-1 zones in Los Altos cap additions at one story, which kills a second-story ADU drawing on paper. A local general contractor has to know which streets fall under which height district before you pay for architectural drawings.

FAQs About General Contractor in Los Altos
The city caps residential floor-area ratio at 45% of lot size, and many older Los Altos homes already sit above 40%, which means a large addition or ADU can be unpermittable as drawn. We pull the survey and run coverage math before design work starts so you don’t pay for drawings the city will reject. Call (254) 272-5876 and we’ll check your property’s coverage at no cost.
A kitchen or bathroom remodel in Los Altos that moves plumbing, electrical, or gas lines requires a building permit and a rough-in inspection before drywall closes the walls. The city inspector verifies the framing, plumbing, and electrical at that point, followed by a final inspection after finishes are installed. We handle the permit filing and schedule every inspection as part of the project plan.
The spread comes from cabinetry grade, countertop material, whether walls move, and whether the contractor includes permit fees and allowances in the bid at all. A $14,000 Los Altos kitchen uses stock cabinets and a laminate counter, while a $45,000 kitchen includes custom Wellborn cabinetry, Cambria stone, and structural changes. We quote the same written line-item format every time so you can compare real numbers.
A draw schedule ties payments to completed, inspected phases of work rather than to a lump sum up front, so you never pay ahead of the work that’s actually finished and signed off. On a Los Altos addition, draws typically release at permit approval, foundation, rough-in inspection, drywall, and final inspection. Every Sawyer Remodeling contract includes a written draw schedule and a final payment held until the punch list closes.
You can absolutely change selections mid-project, and the cost should be a written change order against your original allowance, not a surprise line item at the end. If your Los Altos kitchen allowance was written for Silestone and you choose a higher-grade Cambria slab, we note the difference, get your written approval, and the final invoice matches. Call (254) 272-5876 for a detailed allowance schedule before your remodel starts.
