Construction Services in Avocado Heights, CA
If you own a 1950s or 60s ranch home in Avocado Heights, you already know the telltale signs: single-pane windows that rattle in a Santa Ana wind, a fuse panel that buzzes when the AC kicks on, a kitchen counter that’s two inches lower than it should be. Those houses weren’t built for modern loads, and the county permitting process here doesn’t make fixes any easier if you don’t know it. We’re Barrett & Sons Construction, and we work in Avocado Heights weekly. If you’re planning a remodel, a roof, an addition, or you’ve got a crack in the flatwork that’s getting bigger every August, call (877) 610-1318 and Tom Barrett will answer.

Why Avocado Heights Homeowners Choose Barrett & Sons Construction
Tom started this company in 1998, put his name on the truck, and put his sons on the crews. That’s not marketing language. When you hire us, the person who shakes your hand at the estimate is usually the person who decides how the work gets done. And Tom publishes his name, his address, and his license number on every piece of paper we hand you. Look it up before you sign anything. Ask anyone on your street, or look up the license number yourself. Up in the hills off Workman Mill Road and along the flats near the 605, you’ll find neighbors who’ve had us pull county permits, pass county inspections, and stand behind the finished job with a written 90-Day Done Right Promise. We’ve been on ranch houses in the lower Avenues and remodels tucked behind the old orchard lots off Don Julian Road. The houses change, the paperwork doesn’t: every scope, every allowance, every price change arrives as a written change order before work happens. No surprise invoices at the end, because the allowance that isn’t on paper is a surprise waiting for a date.
Construction Services We Offer in Avocado Heights
Kitchen Remodeling
Older Avocado Heights kitchens often sit on uneven slab floors and carry wiring that predates modern code. We open walls, rethink layouts, and install cabinetry from KraftMaid and counters from Cambria, named brands you can look up before we cut anything.
Learn more about our Kitchen Remodeling in Avocado Heights.

Bathroom Remodeling
Cast-iron drain lines and cramped 5-by-8 footprints are the rule in these 1960s tract homes, not the exception. We handle the plumbing, the waterproofing, and the county inspection sign-off, which out here runs through LA County Building and Safety, not a city office.

Roofing
Avocado Heights Roofing is a challenge: three-tab shingle roofs here don’t age gracefully under 95-degree summers and October wind events. We install GAF and CertainTeed systems rated for inland valley heat, and we document the deck condition before we nail anything down.
Learn more about our Roofing in Avocado Heights.

Windows & Doors
Single-pane aluminum sliders are original to a lot of these houses, and they leak conditioned air like a screen. We install Andersen and Marvin replacements sized to the existing rough openings, so you’re not rebuilding a wall to fix a draft.
Learn more about our Window & Door work across home remodeling projects.

Fence Installation
Larger Avocado Heights lots, some with remnants of old orchard rows, need fences that actually follow the grade. We set posts in the valley’s expansive soil correctly, and every line is pulled to the property line, not to where the last fence sagged.
Reach us at (877) 610-1318 with your lot dimensions for a free fence estimate.

Driveway & Pavers
The clay under 91746 shifts with every wet winter and dry summer. We install paver systems from Techo-Bloc and Cambridge on compacted, properly drained bases so the joints don’t walk apart in July.
Call (877) 610-1318 for a paving quote. We’ll inspect the existing flatwork first.

Home Additions & ADU
This is where the unincorporated part really matters. ADUs in Avocado Heights must meet LA County setback and lot-coverage rules, which differ from what La Puente allows just across the boundary line. We pull county permits, schedule county inspections through the Alhambra-area district office, and build to the code that actually governs your parcel.
Get the full ADU process walkthrough by calling (877) 610-1318.

Why Avocado Heights’s Climate & Housing Affect Construction
Avocado Heights is unincorporated Los Angeles County, and that one fact changes how every construction job here gets permitted. There’s no city building department here to buffer you; plans go through LA County Public Works and Building and Safety, inspections get booked through the county’s Alhambra-area district office, and the inspector who signs off on your kitchen remodel or ADU answers to the county, not your city council. Contractors who only do work in incorporated cities like La Puente or West Covina routinely get the timing wrong out here, because county reviews and inspection queues run on a different calendar. We’ve been through that process enough times that it doesn’t surprise us, and it shouldn’t surprise you either.
The houses themselves add another layer. This community grew out of post-WWII tract development in the 1950s and 60s, and the inventory reflects it: ranch-style homes on slab-on-grade foundations, original single-pane windows, undersized electrical panels, and a lot of original avocado orchard land that still shows in uneven grading, old irrigation pipes where you’d pour a footing, and bigger-than-average lots that complicate add-on construction. The expansive valley clay doesn’t help either; it wets up in winter and bakes dry in summer, and anything we build, pave, or fence on has to respect that movement or it fails within a few years.

FAQs About Construction in Avocado Heights
In most cases, yes. Avocado Heights is unincorporated LA County, so permits come from LA County Public Works and Building and Safety, not a city office. Kitchen remodels, bathroom remodels involving plumbing or structural changes, room additions, ADUs, and roof replacements all require county permits and inspections. Call (877) 610-1318 and we’ll tell you exactly what your project needs before you sign anything.
Most Avocado Heights kitchen remodels run $35,000 to $75,000, with the final number driven by whether we’re moving walls, replacing the subfloor, or upgrading the electrical panel. Because these are older ranch homes, the surprises are usually in the walls, which is why every allowance in our quote is in writing before work starts. Call (877) 610-1318 for a free kitchen estimate on your specific layout.
Only if the scope changes, and only in writing. Every change order at Barrett & Sons Construction gets handed to you on paper before any new work happens. If the allowance isn’t on paper, it’s a surprise waiting for a date. That’s our rule, and it’s been our rule since 1998.
We do. Barrett & Sons Construction pulls every eligible permit and schedules every county inspection on your behalf. The inspector works for you, not for me, which is why I like him. That line isn’t theater; it’s how the process protects you.
Yes, we offer a permanent 10% Senior & Veteran discount on all work in Avocado Heights and surrounding communities. We also offer $40 off any repair over $200, a free second opinion on any written estimate, and no trip charge inside the county. Call (877) 610-1318 and mention which applies to you.
Because county permits in Avocado Heights run through a different system than city permits in La Puente or West Covina, and a contractor who doesn’t know the difference will cost you weeks, if not months. We’ve been through LA County Building and Safety enough times to schedule inspections accurately, prepare the right submittals, and avoid the re-submittal delays that plague out-of-area crews.

What Avocado Heights Customers Say
"His sons run the crews and they were in our house for four months. Not once did I feel I had to be home to keep an eye on things."
- Camila Fuentes"Beautiful work and honest pricing throughout. The project ran about three weeks past the estimate waiting on the cabinets, which was the supplier rather than him, though the delay was still real."
- Genevieve Ashcombe"Full kitchen down to the studs. He found the previous owner had done the wiring himself and it was genuinely dangerous, showed me, and put it right properly rather than boxing it back in."
- Augustus Nwachukwu
