ADU Company in Orange, CA
Kitchen remodeling in Orange usually means reworking a galley kitchen in a 1950s or 1960s ranch home, often one that shares a wall with a wall furnace, an aging panel, or a water heater closet. You’ll want a contractor who has pulled permits in Orange and knows that many of these floor plans cut the kitchen off from the yard. Colonial ADU Builders has served Orange since 2011, handling everything from Old Towne-adjacent cottage kitchens to full ADU interior finish work. Call (877) 265-9846 for a free estimate.
Why Orange Homes Are Different
Orange is a citrus-heritage city of mostly small-lot post-war single-family homes, and its pre-1946 core is dense with single-story ranch houses on lots where the practical ADU site is a rear yard already squeezed by detached garages off alleys. That means ADU work here is often garage-conversion and alley-access dependent, not the big empty-lot new-builds common in newer inland suburbs. We see it constantly in the blocks around Old Towne: a concrete alley, an old two-car garage built in the 1940s, and a water heater that predates the Reagan administration. The Historic Preservation overlay review, not the ADU ordinance itself, is what stalls or reshapes those plans.
Much of Orange is 1950s to 1970s single-story ranch and tract housing, which brings shallow lot setbacks and aging 100-amp electrical panels. That panel is usually the first real constraint. Our crews know Orange’s warm, dry inland climate means ADUs need real cooling and shading design, plus drainage for the occasional heavy winter storm, but you’ll never need to overbuild for snow load. When we quote an Orange job, we are quoting panel upgrades, alley access, historic review timing, and drainage in the same number. The same build in Irvine would not carry those line items.
In the Old Towne-adjacent blocks, the ADU is typically a detached-garage conversion reached from the alley. The historical review timing runs parallel to the building permit, not in front of it, which catches homeowners off guard. Our team has shepherded enough Orange projects through that process to know which elevation changes trigger review and which ones sail through. If you live in 92866 or the surrounding ZIPs of 92865, 92867, 92868, and 92869, the questions you should ask a contractor are: have you built on an alley-access lot in this city, and have you dealt with the Old Towne review board. Most have not.
Our Main Orange Services
Orange homeowners call us most about two things: adding a detached or garage-conversion ADU, and bringing a dated bathroom up to modern function without a full gut when possible. Both run into the same Orange-specific conditions: older panels, historic review overlays, alley access, and post-war floor plans.
ADU Builders in Orange
Detached new-build ADUs in Orange typically go on wide-lot ranch properties in the neighborhoods east of the 55, while garage conversions dominate the alleys behind Old Towne homes. The garage conversion route usually costs less because the shell, slab, and roof already exist. But the panel upgrade, sewer lateral, and historic review are the real variables. We match you to the right ADU product for your lot and budget, not the one we happen to stock. ADU Builders in Orange have to know which prefab formats clear the setback rules on a 5,000-square-foot lot, and which ones simply will not.
Bathroom Remodeling in Orange
Bathrooms in Orange’s post-war tract homes are tight, often 5 by 8 feet, with original cast-iron plumbing and a single vanity. A remodel here usually means replumbing the wet wall, adding a vent fan that actually vents outside, and waterproofing for a shower that will be used daily. On ADU projects, our in-house bathroom crews finish the interior after the shell is up, so the same team handles rough-in through tile. Bathroom Remodeling in Orange often starts with the question of whether the existing tub can stay or the floor joists need reinforcement.

Kitchen Remodeling in Orange
Kitchen remodeling in Orange almost always means working inside a 1950s or 1960s ranch floor plan: a galley layout, a load-bearing wall on one side, and a panel that cannot carry a modern induction cooktop without an upgrade. The specific problem we solve here is reconnecting the kitchen to the rest of the house while respecting the post-war beam lines and the shallow lot setbacks that limit any bump-out. We do the complete interior finish on ADU kitchens as well, using the same in-house crews. Kitchen Remodeling is our most requested service in this city.
Galley Kitchen Reconfiguration
Signs you need it
You have one narrow prep counter, no place for two people to cook at once, and the fridge blocks the only doorway.
What it costs in Orange
In Orange, plan on $28,000 to $52,000 for a full galley reconfiguration including moving plumbing and adding a vented hood.
How we do it
We open the load path, verify what is bearing, then relocate the sink run to the exterior wall and add an island where the old table sat.
Cabinet Refacing and Countertop Replacement
Signs you need it
The cabinet boxes are solid wood and square, but the doors are delaminating and the laminate counters are burned or swollen.
What it costs in Orange
Cabinet refacing and new stone counters in Orange land between $12,000 and $22,000 depending on the countertop material and door style.
How we do it
We replace doors, drawer fronts, and hardware, then template and install the new countertop in a two-day window, including sink and faucet hookup.
Full Kitchen Gut and Layout Change
Signs you need it
The floor plan does not work at all, the plumbing is original 1960s galvanized, and the ceiling shows water damage from an old roof leak.
What it costs in Orange
A full kitchen gut with layout change in Orange ranges from $45,000 to $85,000, with the upper end reflecting structural work and panel upgrades.
How we do it
We strip to studs, fix the framing and electrical, rerun supply and drain lines, then build the new layout with our finish carpenters, tilers, and painters.
What Kitchen Remodeling Costs in Orange
| Item | Typical range in Orange |
|---|---|
| Galley kitchen reconfiguration | $28,000 – $52,000 |
| Cabinet refacing and countertops | $12,000 – $22,000 |
| Full kitchen gut and layout change | $45,000 – $85,000 |
Those numbers assume a 150 to 250-square-foot kitchen in a post-war ranch. The panel upgrade, if needed, adds roughly $3,500 to $6,000, and moving a gas line for the range adds another $1,200 to $2,500. We write fixed-price quotes with no change orders.
How long does a kitchen remodel take in Orange?
Plan on 6 to 10 weeks for a full Orange kitchen remodel, and 2 to 3 weeks for refacing and counters. The permit review at Orange City Hall adds one to two weeks for a layout change that moves plumbing or electrical. Call (877) 265-9846 for a schedule based on your actual square footage and scope.
Will the price change once work starts?
No, unless you add scope or we find an undocumented condition like termite damage or a failed drain line. We write allowances for those unknowns in the contract and every change order goes to you in writing first. For a fixed-price quote in Orange, call (877) 265-9846.
Brands We Service in Orange
Our Orange projects pull from Plant Prefab and Abodu for full-module units, while Tuff Shed kits work well for garage-conversion shells when the existing structure cannot be saved. James Hardie fiber-cement siding is our standard exterior finish on Orange ADUs and bump-outs. For details, see our brands. We stock trim, reveal, and touch-up material locally in Orange so a punch list item does not wait on a freight shipment.

What Orange Customers Say
"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."
— Christine Kim"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Todd Rhodes"Unit came out great and the tenant is happy. The timeline ran long, largely because of how slow the city was on plan check, though a couple of the delays were scheduling on their end."
— Elena Torres
