Fast, Reliable ADU Builders Across Palm Springs
ADU construction in Palm Springs typically runs $180,000 to $450,000 for a detached unit, while garage and casita conversions land between $95,000 and $210,000 depending on what’s hiding behind the walls. Those are real numbers for this market, not national averages that fall apart the moment a permit reviewer opens the file. We know Palm Springs because we work it weekly – from the Movie Colony’s butterfly-roof Alexanders to the poolside casitas strung through Vista Las Palmas and Racquet Club Estates. Call (254) 602-5618 and Russ Delmar will walk you through what your specific lot and structure are going to take.
Here’s what matters most in Palm Springs: most ADUs here are built as vacation rentals, and the city has layered short-term rental permit caps and moratoria in residential zones directly on top of ADU approvals. That means a casita can be fully permitted as a dwelling and still be legally unable to generate the Airbnb income that justified the build. We flag this before you sign anything. No other Coachella Valley city – not Cathedral City, not Rancho Mirage, not Desert Hot Springs – stacks that STR permit-cap risk onto ADU permitting the way Palm Springs does. You need a builder who knows both sides of that coin.
Why Lodgewick ADU Builders Is Palm Springs’s Preferred ADU Builders Company
Lodgewick is the ADU company of the Kingswell family – a specialist in accessory dwelling units, garage conversions, and home additions that’s been building in Southern California since 2010. Our ADU Builders team operates 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 the work isn’t right within 365 days, we come back and make it right. That’s not a slogan. It’s in writing on every contract we hand a Palm Springs homeowner.
What does that look like in practice? When you call, a live person answers – 24 hours a day, 7 days a week. Not a voicemail, not a chatbot. When we quote, the price is written down before a single nail is driven, and it doesn’t change at the door. Our crews arrive in the window we gave you, background-checked and in uniform. And when the job’s done, the site is cleaner than we found it. The Kingswell Way, named because a lodge is a small house on a larger property – which is exactly what an ADU is – is how we operate on every project from Thousand Palms down to the south end of Palm Canyon Drive.
Russ Delmar leads our Palm Springs work. He’s the person who walks your lot, looks at your existing sub-panel, checks the egress on that old casita, and tells you honestly whether this project pencils out before you’ve spent a dollar on design. Homeowners in Palm Springs who’ve been burned by a contractor who vanished after the deposit tend to appreciate that.
JADU in Palm Springs
A JADU – junior accessory dwelling unit – is the quickest, least expensive way to add a rentable or family-ready unit inside the existing footprint of a Palm Springs home, typically running $70,000 to $140,000 when carved out of a spare bedroom or underused den with its own exterior door. JADUs work especially well in Palm Springs’s Mid-Century Modern tract homes, where original floor plans often include a wing bedroom with direct patio access that converts cleanly into a small independent living space with a kitchenette.
Converting an Existing Bedroom Wing
Many 1950s-1970s Alexander and Krisel-designed homes in Palm Springs have a bedroom wing split off from the main living core – which is exactly the layout a JADU needs. The conversion adds a small kitchenette, verifies separate egress, and often requires a dedicated circuit for a compact refrigerator and microwave. Palm Springs’s building department processes JADU applications faster than detached ADUs because the unit stays within the existing structure.
STR Rules and JADUs in Palm Springs
The same STR permit caps that complicate detached ADU rentals in Palm Springs apply to JADUs listed on Airbnb or VRBO. A JADU is a dwelling unit, and renting it short-term in most residential zones requires a permit that may not be available. We tell you this up front – before you invest in a kitchenette and separate entrance. Some Palm Springs homeowners build the JADU for family and skip the rental question entirely, which removes that risk.
ADU Plans in Palm Springs
ADU plans in Palm Springs run $6,000 to $18,000 depending on whether we’re documenting an existing casita conversion or drafting a new detached structure from scratch, and every set we produce accounts for the city’s Architectural Review requirements in Historic Districts like Movie Colony, Tennis Club, and Old Las Palmas. Plans are the cheapest phase of an ADU and the most consequential – a bad plan set is what turns a $180,000 build into a $260,000 change-order mess.
Documenting a Palm Springs Casita Conversion
The original poolside casitas scattered across Palm Springs backyards were often permitted decades ago only as non-habitable guest rooms – no kitchen, no legal egress beyond the sliding glass door. An ADU plan set for one of these structures has to document the full kitchen addition, confirm separate egress, show a dedicated panel upgrade, and clear Architectural Review so the finished structure doesn’t visually violate the home’s Mid-Century character. We’ve done enough of these to know which details the reviewer will flag before they do.
New Detached ADUs and Title 24
For ground-up detached builds in Palm Springs, the plan set carries extra weight because of Title 24 cool-roof requirements. Flat and low-slope roofs – the signature of MCM construction – absorb intense desert sun, so the plan must specify roofing materials and insulation values that pass energy compliance under Coachella Valley heat loads. We size the mechanicals properly at plan stage because retrofitting a ducted system into a small ADU after framing is an expensive correction nobody should pay for.
Trusted Brands We Service in Palm Springs
We work hands-on with several established prefab ADU manufacturers, including Cover and Dvele, and we’ve installed Boxabl units on Palm Springs lots where site access and timeline favored a modular approach. We also specify James Hardie siding on detached ADUs that need to hold up under high-UV exposure and 115°F-plus summer heat without warping or fading. For Palm Springs homeowners, our familiarity with these systems means quicker plan review, accurate factory lead times, and a crew that’s assembled these units before – not figuring it out on your lot.
Common ADU Builders Problems We See in Palm Springs Homes
- Poolside casitas that aren’t legally habitable. The structure’s been a guest room for 50 years, but it has no kitchen, single-direction egress, and a sub-panel that’s been running a mini-fridge and window AC on undersized aluminum wiring since the Eisenhower administration. The conversion cost lands between $95,000 and $160,000 once you add the full kitchen, panel upgrade, and egress corrections.
- Failed waterproofing behind original tile. Casitas and guest baths from the 1950s-1970s often have shower pans that were never properly waterproofed, and 40 years of slow seep has rotted adjacent framing. Opening up that wall kills the fixed-price quote – which is why we write allowances into the contract before touching it.
- Architectural Review rejections in Historic Districts. Movie Colony, Tennis Club, and Old Las Palmas all require the historic review board to sign off on exterior design for any new or converted ADU. A modern flat-stucco box gets rejected. The design has to speak MCM – deep overhangs, clerestory windows, low-slope roof lines. We know what passes because we’ve cleared it multiple times.
- STR permit caps that kill the rental case. A legally built ADU that can’t get a short-term rental permit in a Palm Springs residential zone may sit empty or rent long-term at half the projected revenue. We raise this before you commit, and we’ll help you check current STR permit availability so you’re building with your eyes open.
Pricing for ADU Builders in Palm Springs, CA
Detached ADUs in Palm Springs run $180,000 to $450,000 for new construction; garage conversions land at $95,000 to $180,000; poolside casita conversions to legal ADUs run $95,000 to $210,000 once you account for the panel, kitchen, egress, and waterproofing corrections that almost always show up. JADUs run $70,000 to $140,000. ADU plan sets run $6,000 to $18,000. The big cost swing on conversions isn’t design – it’s what sits behind the walls. A 1962 casita with original wiring and failed shower waterproofing costs real money to correct, and any contractor who quotes you a fixed number without an inspection contingency is gambling with your money. We don’t gamble. Call (254) 602-5618 and we’ll give you a written price, not a verbal ballpark.

FAQs About ADU Builders in Palm Springs
No. The STR permit cap applies to the rental use of any dwelling unit in Palm Springs – including a converted casita – and is entirely separate from ADU building permits. Your casita can pass all building inspections and still be ineligible for a short-term rental permit if the zone is capped or under moratorium. Before you spend $95,000 to $210,000 converting a casita, we help you check current STR permit availability so you’re not building a rental unit that can’t rent. Call (254) 602-5618 and we’ll walk you through what your specific address allows.
In our experience across Palm Springs, you’ll typically find aluminum branch wiring or even knob-and-tube in the oldest sections, undersized framing around original door and window openings, and failed waterproofing behind original tile – especially in casitas and guest baths that haven’t been touched since construction. These conditions trigger code-mandated corrections once walls are open. That’s the single biggest reason a conversion quote moves after demolition starts, which is why we write allowances into the contract and price surprises in writing before touching anything. We don’t eat the cost, and more importantly, we don’t surprise you with it.
Because fixed prices on Palm Springs conversions are fiction. Once we open a 1958 Alexander-era wall, we may find undersized aluminum wiring, rotten framing behind a failed shower pan, or a sub-panel that can’t carry a full kitchen – and someone has to pay for the corrections. A fixed-price contract means the contractor either eats that cost and cuts corners elsewhere, or hits you with a change order you never saw coming. We write line-item allowances for concealed conditions, and any allowance spend is priced and approved in writing before we touch it. The 365-Day Done Right Promise only works if we’re honest about what the job actually is.
Yes. All three are designated Historic Districts in Palm Springs, and any new or converted ADU within their boundaries requires Architectural Review of the exterior design before permits are issued. The review board enforces Mid-Century Modern compatibility – rooflines, window proportions, overhangs, exterior materials. A design that ignores MCM character gets rejected, and redesign after demolition starts is an expensive mistake. We’ve cleared Architectural Review in all three districts, and our plan sets are drawn to pass on the first or second submission, not the fourth.
Because Coachella Valley summers push 115-120°F, and a small ADU can’t support ducted HVAC efficiently under that heat load. Ducted systems lose too much capacity through attic runs, struggle to maintain temperature in small conditioned spaces, and cost more to install. Ductless mini-splits are essentially universal in Palm Springs ADUs – they deliver the cooling capacity a desert summer demands, zone precisely, and meet Title 24 energy requirements more easily. We size them at plan stage so the mechanical load is never an afterthought.
