Fast, Reliable Home Addition Contractor Across Orange
Adding square footage to an Orange home usually costs between $180 and $420 per square foot, with a 400-square-foot bump-out running roughly $72,000 to $168,000 and a full second-story addition landing between $250,000 and $650,000 depending on scope and site conditions. Those are real numbers from our work across Orange, from Old Towne Craftsman bungalows to east-side ranch tracts, and they reflect what you’ll actually see on a written quote rather than a vague ballpark you have to chase down over the phone. If you’re weighing a Home Addition Contractor decision, the smartest first move is a free on-site estimate, because the lot, the panel, the sewer line, and the design-review overlay all change the final number. Call (254) 602-5618 and we’ll walk the property with you.
Why Lodgewick ADU Builders Is Orange’s Preferred Home Addition Contractor Company
Lodgewick ADU Builders operates under The Kingswell Guarantee, which means every Orange project starts with a written price before any work begins, a defined arrival window for crews, a clean job site, and a written guarantee delivered before we drive the first nail. That guarantee includes a free return visit if anything fails within the 365-day period. We know that sounds like a lot of promises, so we put each one in writing on paper, not in a sales brochure.
Russ Delmar leads our Orange work, and he has spent enough time walking Old Towne lots and east-side ranch homes to know which questions to ask before pricing a job. We don’t guess at your panel capacity or assume your floor joists will handle a second story; we look first, then quote. Orange homeowners who’ve been burned before, by a contractor who never showed or a price that changed at the door, tend to respond well to that order of operations. Every call to (254) 602-5618 is answered by a live person, 24 hours a day, seven days a week, so if something comes up mid-build you’re not leaving a voicemail and hoping.
Second Story Addition Contractor in Orange
A second story addition in Orange is a different animal from a ground-floor bump-out, because you’re asking an existing foundation and first-floor framing to carry a whole new level, and on the pre-WWII Craftsman homes in Old Towne that often means engineering work before you can even talk about framing. When your growing family needs bedrooms but your lot can’t expand outward, going up is the right answer, and our Home Addition Contractor in Orange team has done enough of these to know where the surprises hide: undersized footings, knob-and-tube wiring, and ceilings that won’t meet current height codes without reframing. A second-story addition in Orange typically runs $250,000 to $650,000, with the higher end reflecting full tear-off re-roofs, seismic retrofits, and upgraded shear walls required on older homes.
Foundation and Framing Before Finishes
When we scope a second story in Orange, the first thing we look at is what’s holding up the first floor. Many Old Towne homes sit on perimeter concrete foundations that were fine for a single level in 1925 but need supplemental piers and new hold-downs before they’ll pass plan check for a second floor. We price that engineering honestly up front, so your written estimate includes the retrofit rather than discovering it as a change order two weeks in.
Living Through a Second-Story Build
Staying in the home during a vertical addition is rough, and most Orange homeowners don’t. The roofline comes off, the first floor gets weather-exposed, and the house becomes a construction site for four to seven months. Our crews follow The Kingswell Way on every job: we say the price before the work, show up inside the arrival window, leave the site cleaner than we found it, and put the guarantee in writing.
Garage Addition Contractors in Orange
Garage additions in Orange split into two paths, and which one you take depends on whether you’re converting an attached garage on a postwar ranch home east of the 55 Freeway or building an attached addition where no garage existed. For the 1950s-60s tracts that dominate that side of town, converting an existing attached garage into living space is usually the most cost-efficient Home Addition Contractor move, running $60,000 to $160,000 depending on floor condition, ceiling height, and how much of the original slab we can keep. City plan check here, not the Old Towne design-review process, governs the approval, but that’s still a real hurdle.
Seismic Retrofits and Subpanel Upgrades
Postwar Orange garages rarely have the anchor bolts or panel capacity for a permitted conversion. Most east-side garage additions require a seismic anchor-bolt retrofit at the mudsill and a subpanel upgrade before we can pass inspection. We include those line items in the written price, because a garage addition that skips the retrofit will fail plan review, and you’ll pay for it either way.
From Garage to Real Living Space
Converting a garage means more than drywall and a coat of paint. We’re talking insulation to meet Title 24, proper electrical, often a mini-split system because Orange summers run hot, and a bathroom rough-in if your lot can handle the drain line tie-in. The honest range on an Orange garage conversion is $60,000 to $160,000, and we’ll give you a fixed number before work starts, not after we open the walls.
Trusted Brands We Service in Orange
For Orange homeowners considering prefab or panelized construction, we work hands-on with Abodu, Cover, and Dvele, three manufacturers whose ADU systems have become popular for side-yard and backyard placements in the city, and we also handle Abodu repair in Orange when those units need service. We also specify James Hardie siding products on many Old Towne projects, because the Artisan lap profile has passed Design Review Committee scrutiny where fiber-cement alternatives did not. Because we maintain local relationships with material suppliers serving Orange, our customers aren’t waiting on parts shipped from out of state, and we can quote realistic lead times on day one rather than week six.
Common Home Addition Contractor Problems We See in Orange Homes
- Old Towne design-review rejections: The Historic Preservation Design Review Committee has turned down ADU plans for using fiber-cement lap siding or aluminum-frame windows on Craftsman-era properties. That rejection adds months and redesign cost, which is why we always schedule a pre-application meeting before pulling a single permit.
- Knob-and-tube wiring and 60-amp panels: A huge share of 1910s-1940s Orange homes still carry original electrical systems that can’t support added square footage. Upgrading to a 200-amp panel is a standard line item on nearly every addition we price in Old Towne, and the written estimate reflects it from the start.
- Cast-iron and galvanized drain lines: Older Orange plumbing corrodes, and an addition that ties into a failing drain line creates problems you won’t see until after the walls close. We camera the line during scoping and fix what’s failing before the addition goes up, not after a backup.
- Santa Ana wind exposure on roof connections: Orange sits inland enough that fall Santa Ana winds routinely test roof-to-wall connections and attic ventilation. Our additions use enhanced strapping and proper intake-exhaust venting that passes inspection here, where coastal OC cities barely regulate it.

FAQs About Home Addition Contractor in Orange
Yes, in most cases the Historic Preservation Design Review Committee will require your ADU to reflect the architectural character of the primary home, including materials, rooflines, and window profiles, and they have rejected plans using fiber-cement lap siding or aluminum-frame windows on Craftsman properties. That’s why we spec period-appropriate materials like James Hardie Artisan lap siding and wood-clad windows before the first plan submittal. Call (254) 602-5618 to talk through what the committee will accept on your lot.
No, California’s state ADU preemption laws cap how far Orange can restrict accessory dwelling units, so the city cannot simply prohibit an ADU that meets state size, setback, and height standards, but it can and does impose design-review conditions that change your material costs and timeline. Navigating that tension between Sacramento’s pro-ADU mandates and Orange’s local design standards is the defining skill for builders working in this city. We front-load the design-review conversation so you find out what’s required before you’ve spent money on plans.
Expect to spend $60,000 to $160,000, and expect the city to require a seismic anchor-bolt retrofit and likely a subpanel upgrade to 200-amp service before the conversion passes inspection. Standard east-side Orange ranch garages from that era also often need slab leveling and ceiling height corrections. We price those line items in writing before work starts so there’s no surprise at the door.
Orange’s inland summer temperatures push buildings past the point where window units can satisfy Title 24 energy compliance, so mini-split systems are the standard solution for detached ADUs and garage conversions in this city. Mini-splits also work better on the small square footage of an ADU, and they’re quieter. We include the system in the written estimate, not as an add-on.
A second-story addition extends your existing home’s floor plan upward and typically costs $250,000 to $650,000, while a detached ADU is a separate accessory dwelling unit built in the side or rear yard, usually $180,000 to $400,000 in Orange depending on size and finish. The addition route requires foundation and framing retrofits to support the new level, whereas an ADU needs separate utility connections and, in Old Towne, a design-review pass. Both are major projects, and both deserve a written price before work begins.
