Home Additions & ADU in Stanton - One Fixed Price, Permits Handled

Fast, Reliable Home Additions & ADU Across Stanton

Room addition and ADU work in Stanton runs $45,000-$130,000 for most projects, and on this city’s famously tight lots, the real question is rarely “can we build it?” but “can it legally fit?” Stanton’s roughly 3 square miles of 1950s and 1960s tract homes sit on lots often under 6,000 square feet, which means a detached ADU or second-story addition usually requires a hard look at setbacks, zoning, and existing slab conditions before anyone swings a hammer. We’re Barrett & Sons Construction, and we’ve been working through exactly those constraints for this part of Orange County for most of our 29 years in business. Call (877) 610-1318 and we’ll tell you straight whether your Stanton property can support the addition you’re picturing, then put the scope, allowances, and every price change in writing before work starts.

Why Barrett & Sons Construction Is Stanton’s Preferred Home Additions & ADU Company

Stanton homeowners don’t need another contractor who quotes a number on the phone and hands back a different invoice at the door. They need someone who knows that a 1958 ranch on a 5,500-square-foot lot near Cerritos Avenue has different ADU geometry than a 1964 two-story over behind Rodeo Park. That’s where we come in. Tom Barrett put his name, his license number, and his address out in the open because he expects you to look them up before you sign anything. The crews you’ll see in Stanton are his sons and their teams, background-checked and uniformed, not strangers dispatched from three counties away.

Every eligible home addition and ADU we build in Stanton includes permits pulled and inspections signed. We like the inspector on those jobs because he’s the one who makes sure the framing, shear walls, and Title 24 upgrades actually get done, not skipped. Our Stanton customers also get the 90-Day Done Right Promise written on the contract: if something isn’t done right, one call brings Tom back. That promise, plus the Free Second Opinion on Any Written Estimate offer, is why neighbors over near Stanton Central Park keep passing our number along.

Our Home Additions & ADU Services in Stanton

Our Home Additions & ADU team covers the full range of projects Stanton’s housing stock actually needs, from garage conversions that preserve your only off-street parking option to second-story additions that reclaim the yard for the grandkids.

ADU Design & Permitting in Stanton

On a 3-square-mile city like Stanton, where a detached ADU often has to thread a six-foot side-yard setback against an existing block wall, design and permitting come first and framing comes later. We walk your property’s zoning with the city’s requirements on the table before we draw anything, so you know whether the unit you want fits the lot you own. If it doesn’t, we’ll tell you that too, and show you what will fit.

Garage Conversion ADU in Stanton

Garage conversions run $30,000-$80,000 in Stanton and make sense for a lot of these mid-century homes, as long as the existing slab and Stanton Roofing framing can carry the load. Most of the garages we see around 90680 have original minimally-reinforced slabs from the Eisenhower era, so we test before we convert and put the results in writing. A converted garage is often the fastest permitted ADU on a small lot, and it keeps your existing roofline intact.

New Detached ADU in Stanton

A new detached ADU in Stanton runs $90,000-$220,000 depending on size, finishes, and what’s under the soil. The city’s expansive clay soils shift seasonally, so foundation design matters more here than in a sandy coastal town. We account for that from the start, and we don’t treat the foundation as an afterthought line item.

Junior ADU & Interior Conversion in Stanton

For homeowners who don’t want construction in the yard at all, a JADU carved from an existing bedroom or den is often the quietest path to rental income or an aging-in-place space. These projects run on the lower end of the $45,000-$130,000 range for Stanton additions. Because much of Stanton’s 1950s wiring is early-generation aluminum and the plumbing is galvanized, we include the upgrade scope in the first written estimate, not as a surprise change order later.

If your addition touches the kitchen or bath as part of the plan, we also handle Kitchen Remodeling in Stanton and Bathroom Remodeling in Stanton with the same written-change-order discipline. One crew, one contract, one name on the truck.

Trusted Brands We Service in Stanton

On every Stanton addition and ADU, the materials get named on the estimate the same way the labor does. We install Simonton and Ply Gem Windows & Doors - Stanton options because they hold up through the Santa Ana seasons and keep the Title 24 energy calculations honest. For coastal-adjacent inland exposure like Stanton’s, PGT impact-rated windows are worth considering on the windward side of the house. You can look up every brand before you sign, and you should.

Common Home Additions & ADU Problems We See in Stanton Homes

• Lots that can’t legally fit what the owner wants. Stanton’s pre-1960 tract lots are small, and the city’s setback requirements were written for an era when ADUs didn’t exist. We do the pre-permit zoning and site survey before any framing discussion, because a variance that isn’t approved is a foundation that never gets poured.
• Original slabs that have moved. Orange County’s expansive clay soils push against lightly-reinforced 1950s slabs, and we regularly find cracks or settlement in Stanton before an addition ever starts. We inspect first and put the floor plan on a foundation that will actually carry it.
• Outdated framing on second-story candidates. Homes built in Stanton before current California seismic codes often lack the shear strength required for a vertical addition. We add the shear walls, hold-downs, and strapping the inspector wants to see, and we show you the signed inspection card when it’s done.
• Aluminum wiring and galvanized supply lines. When you open a wall in a 1962 Stanton original to tie in an addition, you find what’s inside. We plan for that upgrade in the estimate and the permit, so it’s not a surprise sitting in your drywall.
