Fast, Reliable Home Addition Contractor Across Redlands
A home addition in Redlands typically costs between $180 and $340 per square foot depending on scope, finishes, and whether you’re adding a room, a second story, or a detached ADU. Most Redlands projects run 4 to 9 months from signed contract to final inspection, with design review and long-lead materials setting the pace far more than framing labor. Our team knows exactly how Redlands’s permitting process, historic district rules, and 100-degree-plus summers shape both the schedule and the final price. If you want a real number in writing before anyone swings a hammer, call (254) 602-5618 for a free estimate.
Why Lodgewick ADU Builders Is Redlands’s Preferred Home Addition Contractor Company
We’re the ADU company of the Kingswell family, building room additions, second-story additions, and detached accessory dwelling units across Redlands since 2010. Every project we take on operates under The Kingswell Guarantee: a written price before any work begins, a defined arrival window for every crew visit, a clean job site at the end of each day, and a written guarantee with a free return visit if anything fails within 365 days. That’s not a marketing line. It’s the document you sign before we order a single board.
Redlands homeowners keep calling us back for one reason: we say the price before the work. No change orders at the door. No “we discovered something” conversations that turn into a bigger invoice. Russ Delmar, who leads our Redlands projects, has walked enough citrus-boom-era lots to know exactly where surprises live: old packing-shed pads, clay irrigation pipe, undersized electrical panels. We plan for what’s under the dirt before we break ground, and we put that plan in writing.
When you call us, a live person answers. Not a voicemail, not a chatbot. That matters at 9pm when you’re wondering whether your second-story addition will clear design review in time for your cabinet order.
Room Addition Contractor in Redlands
A Room Addition Contractor in Redlands handles ground-floor additions built onto the back or side of an existing home, and on the estate lots that define this city, the process often starts with three questions: will the City’s Historic District design-review overlay require a specific roofline, can the century-old utility feeds carry the added load, and what’s hiding in the soil where the new foundation goes. Our Redlands clients most often need room additions when a growing family has outgrown a Craftsman bungalow or Victorian-era foursquare but doesn’t want to leave a neighborhood they’ve lived in for fifteen years. A single room addition in Redlands typically runs $55,000 to $110,000 depending on size and finish level, with master suite additions landing at $95,000 to $160,000.
Ground-Up Foundation Work on Old Citrus Lots
Redlands’s 1880s-to-1920s boom left some of the Inland Empire’s largest residential parcels, but those lots were working groves first. We regularly encounter concrete-lined irrigation channels, clay tile drainage pipe, and packing-shed equipment pads when we excavate. We document what we find, re-route what needs re-routing, and keep the foundation pour on schedule whenever the city’s timeline allows it.
Utility Evaluation Before the Nail Gun Comes Out
Many homes in the historic neighborhoods off Highland Avenue and around the Redlands Bowl still run on undersized panels and galvanized supply lines. Before we frame a single wall, we check what the new square footage will demand and what the existing service can actually deliver. Upgrading to a 200-amp panel or replacing a cast-iron sewer lateral mid-build is far more expensive than identifying it early.
Second Story Addition Contractor in Redlands
A Second Story Addition Contractor in Redlands does two things most other builders treat as afterthoughts: verify that the original footings can support another floor of live load, and design the new upper story so the Historic District design-review board signs off on exterior compatibility. On the two-story Victorians and Craftsman homes that give this city its character, a second story addition commonly runs $120,000 to $200,000 for a two-bedroom upper floor, and the biggest variable is always the review queue, not the cost of lumber. Our Redlands clients pursue second-story additions when they don’t want to sacrifice yard space on a large estate lot, and when they’ve already confirmed their parcel isn’t constrained by a preservation easement.
Historic District Exterior Compatibility
Redlands’s design-review overlay is stricter than anything in San Bernardino or Loma Linda. The same window or trim profile that clears quickly in a newer subdivision can get rejected here because it doesn’t match the home’s original architectural language. We build the exterior trim package around that review, ordering the millwork only after the compatibility sign-off. That matters because custom architectural glass and specialty trim can run 8 to 14 weeks once released to the shop.
What Happens When the Review Dog Stops the Order
Releasing long-lead custom materials before design review signs off is the most expensive mistake a Redlands homeowner can make. We’ve seen builders order windows, have the review require a different mullion profile, and then pass the change-order cost to the client. Our fixed written price and sequencing – review first, then order – is why our clients never eat that cost.
Trusted Brands We Service in Redlands
We work daily with the prefab and panelized ADU manufacturers that match Redlands’s lot sizes, historic compatibility requirements, and 105°F summer reality. For detached ADUs on the larger estate lots, we regularly build with Abodu and Cover units because their exterior profiles adapt well to Craftsman-era neighborhoods. For clients who want the tightest possible thermal performance on a Redlands lot that swings 30 degrees between day and night, we use Dvele’s panelized shell and pair it with beefed-up attic insulation. For our Redlands customers we keep local stocking relationships with regional suppliers, so replacement parts and warranty fixes don’t come from a warehouse three states away. When you build with our team, you get a hands-on partner who has actually installed and serviced these systems in Redlands’s specific climate, not a generic contractor learning them on your dime.
Common Home Addition Contractor Problems We See in Redlands Homes
- Historic district design-review delays stopping long-lead orders. Custom cabinetry and architectural glass can’t be released to the shop until the review board signs off on exterior compatibility. Start the review after ordering, and you’ll pay change-order costs when the window or trim profile gets rejected.
- HVAC sized for coastal assumptions. A builder who prices the equipment off San Diego or Orange County loads will undersize it for Redlands’s basin heat. Summer highs above 105°F and daily swings over 30 degrees mean the new space never holds temperature, and you’ll be retrofitting a bigger unit within two years.
- Century-old service lines failing mid-build. Undersized panels, galvanized supply lines, and aging cast-iron sewer laterals are standard on the citrus-era homes that define Redlands’s historic districts. Skipping the pre-connection evaluation means discovering the upgrade after drywall is up, and paying double for demolition access.
- Buried citrus infrastructure stalling excavation. Remnant concrete-lined irrigation channels and poured packing-shed pads hide under many of the older estate lots. Contractors who don’t anticipate them burn project weeks re-routing drainage and re-pouring, and the homeowner eats the delay.

FAQs About Home Addition Contractor in Redlands
Redlands’s design-review overlay requires ADU exteriors to be architecturally compatible with the Victorian, Craftsman, and Mission Revival main houses on the same parcel. That compatibility review doesn’t exist in San Bernardino or Loma Linda, where the same ADU plan can clear review far faster. In Redlands, that review queue, not framing labor, is what usually sets the first inspection date. Call (254) 602-5618 and we’ll tell you exactly where your project sits in that queue before you sign anything.
Lead times. Custom millwork, architectural glass, and specialty cabinetry can run 8 to 14 weeks once released to the shop. Framing crews work in days. In Redlands specifically, the sequencing matters double because you can’t release those long-lead orders until the Historic District design review signs off on exterior compatibility. Our fixed written price and review-first sequencing protect you from the change-order cost when that review requires a different window or trim profile.
No, not honestly. On Redlands’s older estate lots we routinely encounter poured-concrete packing-shed pads, clay irrigation pipe, and remnant citrus drainage channels. On a Craftsman bungalow parcel off West Fern Avenue, our crew hit both a packing-shed pad and a run of clay pipe while excavating. We paused, documented it for the city, re-routed drainage, and re-poured. Because the homeowners had already signed a fixed written price, the discovery changed the calendar but not their number.
Completely differently. Redlands sits in the Inland Empire basin at the foot of the San Bernardino Mountains, where summer highs regularly exceed 105°F and the daily temperature swing can top 30 degrees. Equipment and insulation sizing runs noticeably heavier than coastal California projects of the same square footage. We size every Redlands addition for those basin conditions, not for a San Diego or Orange County load table. Call (254) 602-5618 and we’ll run the actual calculation for your square footage and orientation.
Frequently, yes. Redlands’s century-old homes commonly retain undersized electrical panels, galvanized supply lines, and aging cast-iron sewer laterals. Any of those can fail under the added load of a room or second-story addition. We evaluate all three before we frame, so the upgrade is planned and priced in writing rather than discovered mid-build. Estimates are free, and the number we give you is the number you pay.
