ADU Company in Orange, CA

Kitchen remodeling in Orange usually costs $28,000 – $65,000 for a full replacement in the 1940s – 60s ranch homes that fill most blocks here, with smaller refreshes starting around $14,000. What makes Orange different from neighboring cities is the housing stock: single-story stucco-and-woodframe ranches on shallow slabs, many with original floor plans where the kitchen was never designed for how families cook today. We’re Silverleaf ADU Builders, and we’ve served Orange since 2016. Our team handles ADU construction, bathroom remodeling, and kitchen remodeling under one roof, so the same crew that understands your home’s framing, electrical, and plumbing can carry a project from first hammer to final walkthrough. Call (833) 404-5214 for a free estimate on any of it.

Why Orange Homes Are Different

Most of Orange’s housing stock was built between the 1940s and 1960s, and it shows in the details that matter for remodeling. The typical home is a single-story ranch on a shallow concrete slab with a detached two-car garage out back, reached by a narrow driveway. Interior walls are often 2×4 framing with original electrical panels that were sized for an era of one television and a few lamps, not a modern kitchen with dedicated circuits for induction ranges, microwaves, and under-cabinet lighting. When we open up a 1950s kitchen in the tracts east of the Plaza, we regularly find cast-iron drain lines, cloth-wrapped wiring, and floor joists that have settled unevenly over 60-plus years. None of that is a reason to avoid remodeling, but it is a reason to plan for it in the budget before the first cabinet comes out.

The weather matters too. Inland Orange County warmth means these homes were built with cooling in mind more than heating, and that translates to kitchens that trap heat during hot, dry late summers. We spec ventilation, insulation, and appliance placement around how an Orange kitchen actually behaves in August, not how a kitchen behaves in a coastal microclimate twenty miles west. And in Old Towne around the Plaza, homes may fall under historic district review that shapes window trim, rooflines, and exterior changes. The same remodel one mile east in a 1950s tract runs through a different approval path than it does on a Craftsman street near the circle.

Our Main Orange Services

Two services dominate the calls we get from Orange homeowners. Both involve the same older housing stock, the same permit quirks, and the same need for a contractor who knows how these homes were put together in the first place.

ADU Builders in Orange

Orange is a heavily owner-occupied, post-war single-family town, and the ADU market here is dominated by garage conversions and “over-the-back-garage” units tucked into mature, tightly-platted lots. Detached two-car garages on narrow driveways are the signature starting point, whether you’re converting an existing structure or building new above it. We handle the full scope, from lot assessment and setback checks through utility tie-ins to a finished interior. Learn more on our ADU Builders in Orange page.

Bathroom Remodeling in Orange

Original 1950s and 60s bathrooms in Orange ranches tend to be small, with 5-foot tubs, single vanities, and tile set over drywall that has been absorbing moisture for half a century. The work usually involves reconfiguring a tight footprint, updating the subfloor, and bringing shower waterproofing up to current code. We handle the full remodel, including moving walls where the layout allows it. See the details on our Bathroom Remodeling in Orange page.

Kitchen Remodeling in Orange

Kitchen remodeling in Orange means working inside the homes that define this city: 1940s – 60s single-story ranches with modest square footage and floor plans that predate the open-concept era. The typical job involves opening a closed-off kitchen toward a dining area, rerouting plumbing and electrical through original framing, and upgrading from a slider or window over the sink to something that actually moves air during a hot, dry Orange summer. Our scope continuity matters here: we handle the kitchen interior ourselves rather than stopping at the shell, so decisions about walls, windows, and finishes are made by the same team that draws the plans. For a broader look at how we approach this work, see our Kitchen Remodeling page.

Galley Kitchen Conversion

Signs you need it

The original 8-foot galley kitchen in a 1950s ranch leaves two people unable to pass each other while cooking, and the wall separating it from the dining room cuts off light and conversation.

What it costs in Orange

Expect $32,000 – $55,000 in Orange depending on whether the wall you’re removing is load-bearing and how much you’re moving plumbing and gas.

How we do it

We confirm which walls are structural, design a new sightline, move utilities along existing joist bays where possible, and rebuild the opening with proper headers before any finish work begins.

Full Kitchen Replacement

Signs you need it

Cabinets are delaminating, the original 1960s layout wastes a corner, and the electrical panel cannot support a second countertop appliance circuit.

What it costs in Orange

A complete gut and rebuild in Orange runs $45,000 – $65,000, including new cabinets, counters, flooring, plumbing, and dedicated appliance circuits.

How we do it

We demo to studs, update framing where settlement has moved things, run new electrical and plumbing, install cabinets and counters, and finish with flooring, backsplash, and lighting.

A full kitchen remodel in Orange typically costs $45,000 – $65,000, while cabinet refacing with new counters runs $14,000 – $22,000. Older ranches often carry hidden costs in electrical and plumbing, which we identify during the estimate. Call (833) 404-5214 for an exact quote.

Will the price change once you open up the walls?

Not without your written approval. We quote with a written line-item scope and only adjust if you request changes or we uncover a condition no one could have known existed, like a buried cast-iron drain we confirm together. Call (833) 404-5214 to see how we structure our estimates.

What Orange Customers Say

★★★★★ 4.8 from 4+ reviews

"Garage conversion to a one bedroom unit. He handled the plans, the city submittal, and every round of corrections. Took six months from first meeting to final inspection and he never once made the permit process my problem."

— Marcus Carter

"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."

— Carlos Guzman

"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."

— Kelly Kowalski
