Construction in Los Serranos comes with a set of rules most contractors never see until the inspector walks the job. If your home sits in the Chino Hills fire zone, Title 24 WUI standards apply to nearly every remodel, addition, and re-roof. That changes materials, venting, and the way permits get pulled. We know the 91709 terrain, we know the inspectors, and we answer the phone at (877) 610-1318 when you have questions.

Why Los Serranos Homeowners Choose Barrett & Sons Construction
Most of our Los Serranos work comes from neighbors telling neighbors. Homeowners near the Los Serranos Country Club and along the hillside streets above Pipeline Avenue have watched our crews work, then called when their own project came up. Tom Barrett puts his name, his address, and his license number on every contract. Look it up before you sign anything. That level of openness matters to people who have been burned by an out-of-town outfit that quoted one price on the phone and showed up with another.
The crews carrying the Barrett & Sons name are background-checked, uniformed, and led by Tom’s sons. We’re not a franchise dispatching strangers to Los Serranos. When a permit inspector checks your attic vents for the 1/16-inch mesh screens the WUI code requires, we want that inspection to pass the first time. It usually does, because we knew the rule before we opened the wall.
Construction Services We Offer in Los Serranos
Kitchen Remodeling
Our Kitchen Remodeling in Los Serranos covers everything from 1920s country-club cottages with plaster walls to 1990s hillside homes ready for a full rework. We install KraftMaid and Cambria, and every allowance gets written down before a single cabinet is ordered.
Learn more about our Kitchen Remodeling in Los Serranos.
Bathroom Remodeling
Bathroom Remodeling - Los Serranos is a different animal than a flat-lot Chino job, thanks to hillside plumbing and older cast-iron waste lines. We plan for what’s behind the tile, not just what goes on top. Schluter waterproofing and Sterling fixtures are in our standard rotation.
Learn more about our Bathroom Remodeling in Los Serranos.
Roofing
Los Serranos Roofing must account for the designated Wildland-Urban Interface fire zone, which means Class A assemblies and ember-resistant venting are not optional upgrades. GAF materials hold up to the Santa Ana wind events that funnel through these hills every fall.

Windows & Doors
Windows & Doors in Los Serranos often reveals hidden issues on older ranch homes, like framing that predates current shear-wall codes. We address what the inspector will look for, and we install Andersen and Marvin products you can research by name.
Fence Installation
Hillside fence lines in Los Serranos rarely follow a straight grade, and posts set in expansive clay soil will move if they are not engineered for it. We plan footings around the soil, not the other way around.
Driveway & Pavers
Driveways on hillside lots need proper drainage and base preparation, especially when summer temps push past 100°F and concrete cures fast. We schedule pours deliberately and use Belgard and Techo-Bloc hardscape products.
Home Additions & ADU
Any meaningful new construction in Los Serranos will need engineered foundations, not a standard slab. Clay-heavy hillside soils and WUI cladding requirements drive the design, and we plan for both from the first site visit.
Neighborhoods We Serve in Los Serranos
Our crews work throughout the 91709 zip code, including the streets around the Los Serranos Country Club, the hillside homes off Los Serranos Road, and the newer tract developments near Pipeline Avenue. Response time for estimates inside Los Serranos is typically the same week you call. Here is where we are most active:
- Los Serranos Country Club area
- Los Serranos Road corridor
- Pipeline Avenue and adjacent streets
- Hillside tracts above Butterfield Ranch Road
- Southern edge near Chino Hills State Park boundary
Why Los Serranos’s Climate & Housing Affect Construction
Los Serranos sits squarely within California’s designated Wildland-Urban Interface fire zone in the Chino Hills. Nearly every project we touch here, additions, re-roofs, new builds, must meet Title 24 WUI fire-resistant standards: Class A roofing assemblies, ember-resistant 1/16-inch mesh attic venting, and ignition-resistant exterior cladding. These requirements do not apply to flat Chino or Ontario just a few miles to the west. Contractors who mostly work those flat-lot cities routinely miss the vent-screen detail, and that is exactly what the Chino Hills permit inspectors check first. An allowance that isn’t on paper is a surprise waiting for a date, and a WUI code correction ordered mid-project is the same kind of surprise, except the inspector delivers it.
The housing stock compounds the challenge. The oldest residential core clusters around the Los Serranos Country Club, established in the 1920s, where mid-century cottages and ranch-style homes predate modern seismic, fire, and energy codes. These sit alongside 1980s through 2000s hillside tract homes with varying foundation designs. Expansive clay soils common to the Chino Hills mean foundation heave, cracked slabs, and inadequate shear walls are recurring issues we address on renovations. Santa Ana wind events funnel through these hills each fall and winter, accelerating ember travel, and summer temps routinely exceed 100°F, which means we schedule exterior concrete pours and roofing work carefully to avoid heat-related material failures. Seasonal wet-dry cycles drive significant ground movement, so engineered foundations, not standard slabs, are the norm for any meaningful new construction here.

FAQs About Construction in Los Serranos
A kitchen remodel in Los Serranos typically runs $35,000 to $90,000 or more, depending on whether you are updating an older country-club cottage with hidden plaster and wiring issues, or reworking a newer hillside tract home. Hillside access that requires staging can add labor cost. Call (877) 610-1318 and Tom will give you a written scope and allowance list before anything is ordered.
Not without a written change order that you sign first. Every scope change, every allowance adjustment, every unexpected condition gets documented on paper and priced before we touch it. That is our standing practice on every Los Serranos job, and it is written into the contract.
Yes. Every eligible job includes permits pulled and inspections signed. In the Los Serranos WUI fire zone, that means Chino Hills inspectors will verify ember-resistant 1/16-inch mesh screens at attic and sub-floor vents, Class A roofing, and ignition-resistant cladding. We build to those standards from day one. The permit inspector works for you, not for me, which is why I like him.
Most Los Serranos bathroom remodels run two to four weeks, depending on whether we are working around aging cast-iron waste lines and hillside framing that requires shear-wall upgrades. A simple fixture and tile swap moves faster than a full gut with plumbing relocation. We will give you a date range in writing before the first hammer swings.
We do. Many of those 1920s through 1960s cottages and ranch homes predate current seismic, fire, and energy codes, and foundation heave from expansive clay soil is a regular find. We plan renovations around what the home actually has, not what a flat-lot brochure assumes. Call (877) 610-1318 to schedule a walk-through and we will give you a straight read on what the job needs.
If you are ready to get a real number for construction work in Los Serranos, call (877) 610-1318. A live person answers, day or night. Ask about our free second opinion on any written estimate, the $40 off any repair over $200, and the permanent 10% senior and veteran discount.
