Fast, Reliable Home Addition Contractor Across Palm Springs
Home addition costs in Palm Springs typically run $185 – $320 per square foot depending on the scope, with room additions starting around $45,000 and full second-story builds commonly reaching $180,000 – $350,000. We’re Lodgewick ADU Builders, the ADU and home addition company of the Kingswell family, and we’ve been building additions and casitas across Palm Springs since 2010 under The Kingswell Guarantee: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee on every project. If you’re weighing a second story, a garage addition, or a casita conversion off Gene Autry Trail or Palm Canyon Drive, call (254) 602-5618 and you’ll get a live person, not a voicemail loop.
Palm Springs construction is not like building in Riverside. Architectural Review in the historic districts, Title 24 cool-roof mandates, and the short-term-rental permit cap all shape what gets approved, what gets ordered, and what the final number is. We know those layers because we work inside them every week. You deserve a contractor who can tell you the real price before a single nail is driven, and who will put that price in writing.
Why Lodgewick ADU Builders Is Palm Springs’s Preferred Home Addition Contractor Company
Homeowners across Palm Springs keep calling us back for one reason: we say the price out loud, first, in writing. Russ Delmar leads our team, and he runs every project under The Kingswell Guarantee. That means you receive a written, line-item price before we order so much as a single cabinet. If the work isn’t done right, our 365-Day Done Right Promise puts it in writing that we’ll come back and make it right, free, within the guarantee period. No Palm Springs homeowner should have to guess whether a contractor will actually return a phone call after the check clears.
Our crews serving Palm Springs are background-checked and uniformed, so you always know who is on your property. We coordinate scheduling and dispatch from the brand’s Inland Empire office, which keeps response times to Palm Springs neighborhoods like Little Tuscany, Vista Las Palmas, and Sunrise Park steady and predictable. When you call with a question about your build or your guarantee, a live person answers. At 2 p.m. on a Tuesday or 2 a.m. on a Saturday, the phone is answered by a human being.
We work hands-on with leading ADU and prefab brands including Abodu, Cover, and Dvele, matching each one to the homeowner’s lot, budget, and restoration requirements. That matters in Palm Springs because a prefab panelized system that works in a suburban cul-de-sac may not clear Architectural Review in the Movie Colony, where MCM-compatible exterior detailing is mandatory.
Second Story Addition Contractor in Palm Springs
A second story addition in Palm Springs is usually the right answer when a homeowner on a large desert lot wants more square footage without sacrificing pool or yard space. Second-story work here runs $220 – $350 per square foot, which means a 600-square-foot upstairs addition typically lands between $132,000 and $210,000 before design and Architectural Review fees. The cost is driven less by labor and more by what gets ordered: engineered lumber or steel, architectural glass, custom millwork, and a mechanical system sized for a footprint that now spans two floors under Coachella Valley sun.
One truth about second-story additions in Palm Springs that nobody mentions until it’s too late: the calendar is set by lead times, not by how many framers show up. Custom windows with low-E glazing and MCM-compatible frames can take 10 – 14 weeks. Architectural glass for a stairwell or a primary suite takes longer. If you order before Architectural Review signs off and the elevation changes, you eat the re-order. Russ Delmar’s team fixes the price in writing before any of those orders go out, so the schedule and the number stay aligned.
Structural and Mechanical Upgrades
An upstairs addition in a 1950s Alexander-built home means the existing slab and wall system needs evaluation before a single board goes up. Many of these Mid-Century homes were never engineered for a second floor, so we often spec steel moment frames or supplemental shear walls. The mechanical side is where Palm Springs bites hardest: an upstairs addition without a properly sized ductless mini-split system will be unusable from June through September, when outdoor temperatures routinely push 115°F.
Architectural Review and MCM Compatibility
If your home sits in the Movie Colony, Tennis Club, or Old Las Palmas historic districts, the second-story elevation must pass Architectural Review. That means the roofline, window patterns, and cladding have to read as original, not bolted-on. Russ Delmar has steered multiple Palm Springs additions through that review with MCM-compatible detailing. He treats the elevation drawing as a schedule variable, not an afterthought.
Garage Addition Contractors in Palm Springs
Garage addition contractors in Palm Springs do two very different jobs: either adding a new garage structure to a lot that never had one, or converting or expanding an existing detached garage. A new two-car garage addition typically runs $55,000 – $95,000 in Palm Springs, while a garage conversion into living space runs $145 – $260 per square foot depending on whether it becomes an ADU, a guest suite, or a studio. What makes garage work different in Palm Springs is the sheer number of original detached garages from the 1950s and 1960s, many with flat or low-slope roofs that demand Title 24 cool-roof assemblies.
We’re extremely familiar with Palm Springs’s housing stock. A large share of our garage addition inquiries involve a detached garage that was built by the Alexander Construction Company and has never been insulated, never had proper electrical, and never been permitted for habitable use. Homeowners see a shell with a door and think fast conversion. We see roof replacement, sub-panel replacement, insulation, and often a full re-stub of the plumbing.
Garage Conversions vs. New Garage Additions
A conversion is usually cheaper and faster than a new build, but only if the existing slab and roof structure are sound. In Palm Springs, a 1960s garage slab is often fine, but the roof over it may need a complete cool-roof re-roof to meet Title 24. A new detached garage addition avoids those unknowns, but adds site work, foundation, and longer city approval timelines.
Casita-Grade Garage Additions
Many Palm Springs homeowners want the garage to do double duty: car storage now, casita later. We design garage additions with ADU-ready rough-ins, so the electrical, plumbing, and egress pathways exist for a future conversion. That’s a smarter Palm Springs play than most people realize, because the STR permit cap means building an ADU-ready garage preserves your options without triggering the rental-permit question on day one.
Trusted Brands We Service in Palm Springs
Our Palm Springs customers frequently ask which prefab and panelized systems we install, service, and finish. We work directly with Abodu, Cover, and Dvele, three of the most established names in California ADU construction. We maintain strong relationships with their design and engineering teams, which means when a spec changes mid-project, we’re not emailing a black hole. For Palm Springs specifically, we can tell you which of those brands’ standard models typically clear Architectural Review in the historic districts and which will face pushback. That kind of local knowledge saves months of back-and-forth, and we’re glad to share it before you buy.
Common Home Addition Contractor Problems We See in Palm Springs Homes
Palm Springs throws curveballs that a generic Southern California contractor simply doesn’t see. Here are the problems we encounter most often:
- Ordering before Architectural Review sign-off. Custom cabinetry, MCM-compatible doors, and architectural glass ordered before the Historic Site Preservation Board approves the elevation. One elevation change after review forces re-orders, re-review, and a delay that can stretch past a full season. We sequence orders around review, not in front of it.
- Mechanical sizing copied from a normal house. A ducted system that works in a 2,000-square-foot tract home can’t efficiently serve a 500-square-foot casita at 118°F. Ductless mini-splits are essentially universal in Palm Springs ADUs for this reason, and the load calculation has to be done on the actual envelope, not a rule of thumb. Title 24 cool-roof compliance on flat and low-slope MCM roofs is non-negotiable and easy to miss if the contractor doesn’t work here regularly.
- Poolside casita conversions that skip the sub-panel. Original Palm Springs casitas were permitted as non-habitable guest rooms, often with a mini-fridge and a window AC on a sub-panel from the Eisenhower era. We see homeowners discover after drywall that the panel can’t handle a real kitchen and a mini-split. The permit then requires a full panel upgrade, and the budget takes a hit no one priced in.
- STR permit assumptions that quietly kill the pro-forma. Palm Springs caps short-term rental permits and has moratoria in residential zones. A homeowner builds an ADU to list on Airbnb, then discovers no new TOT/STR permit is available. The financial case for the whole project evaporates. We raise this in the first conversation, not after the slab is poured, because no contractor who knows Palm Springs can honestly ignore it.

FAQs About Home Addition Contractor in Palm Springs
The short answer is maybe, but only if a TOT/STR permit is available for your zone before you break ground. Palm Springs caps short-term rental permits and has imposed moratoria in some residential zones, which means an ADU built for Airbnb or VRBO use can be dead on arrival financially if the permit isn’t already secured. We raise this question in the first conversation on every Palm Springs casita project. Call (254) 602-5618 and we’ll walk you through what your specific zone allows before you spend a dollar on design.
Yes, if the home sits in a designated Historic District like Movie Colony, Tennis Club, or Old Las Palmas. The conversion must pass Architectural Review, and exterior changes need to be MCM-compatible so the addition reads as original, not bolted-on. Our team includes that review as a schedule variable from day one. It’s not a roadblock, but it is a gate, and ignoring it leads to re-orders and re-review.
Ductless mini-split systems, almost without exception. Palm Springs summers routinely hit 115 – 120°F, and a small ADU can’t be efficiently served by a ducted system designed for a much larger footprint. We run real load calculations and pair the mini-split with a Title 24 cool-roof assembly on the flat or low-slope MCM roof. That combination is the make-or-break variable for comfort and energy cost in a Palm Springs casita.
The conversion requires adding a full kitchen, confirming separate egress, and usually upgrading a sub-panel that has spent 40 years running only a mini-fridge and a window AC. In Old Las Palmas recently, we converted a 1962 poolside casita, originally permitted only as a non-habitable guest room, into a legal ADU with a full kitchen, separate egress, a new sub-panel, and a Title 24 cool-roof assembly over the low-slope roof. We spec’d a ductless mini-split and ran the Architectural Review with MCM-compatible detailing so the addition read as original. Long-lead items like custom cabinetry, architectural glass, and the mini-split set the calendar; framing and labor fit around them, not the reverse.
Because long-lead items, not labor, drive the schedule and the budget on high-end work. Custom cabinetry, architectural glass, and MCM-compatible doors can take 10 – 14 weeks to arrive, and if the price isn’t fixed in writing before those orders go out, a change in spec or material price lands on you. The Kingswell Guarantee means you get a written price before any work starts, and that price holds. Call (254) 602-5618 to schedule a free estimate and get your number in writing.
