Palm Springs isn’t like the newer developments to the west. This is a village of 1950s-1970s CBS ranch homes, flat roofs, and terrazzo floors - a mid-century footprint that predates modern Florida Building Code wind-mitigation standards. That matters. Pull a permit for any addition or ADU here, and Palm Beach County will require upgrades that newer cities skip. We’ve learned to build that reality into every estimate we deliver in the 33406 ZIP code.
Why Groundwork Construction Co. of South Florida Is Palm Springs’s Preferred Home Additions & ADU Company
We’ve been building and expanding homes across Palm Beach County long enough to know Palm Springs’s specific headaches. The original jalousie windows. The shallow water table that turns a simple footing pour into a dewatering operation. The county inspectors who’ve seen every shortcut and don’t miss a thing.
Our crews respond to Palm Springs within a day of initial contact, and we schedule site visits to accommodate the working families and retirees who make up most of the village’s homeowners. Raymond Estevez, who leads Groundwork, personally reviews every ADU and addition project before it goes to permit - he’s caught more than one design that would have triggered a costly wind-mitigation surprise.
Homeowners in Palm Springs choose us because we don’t hand off projects. One contractor handles your ADU site prep, the addition framing, the window upgrade the county demands, and the final tie-in to your existing roofline. That’s the difference between a six-month project and a year-long ordeal.
Our Home Additions & ADU Services in Palm Springs
ADU Design & Permitting
Every ADU in Palm Springs starts with a realistic permit strategy. We map your property setbacks, check Palm Beach County’s wind-load zone requirements, and identify which elements of your existing home will trigger mandatory upgrades. If you’ve got original jalousie windows - and many homes on Kirk Road and the interior streets do - we flag that upfront so you’re not blindsided by a county inspector six weeks into construction. Our design team produces permit-ready drawings that account for these Palm Springs-specific conditions, not generic templates from another market.
Garage Conversion ADU
Garage conversions are popular in Palm Springs because so many homes have detached structures that already have power and a slab. But there’s a catch. That detached garage probably has the same jalousie windows as the main house, and converting it to living space triggers the same wind-mitigation upgrade path. We recently converted a detached garage into an ADU on a 1950s CBS ranch on Kirk Road. The county inspector flagged the original jalousie windows, so we upgraded to impact-rated units and added a heavier-duty spring system for the oversized garage door - completing the job in one trip, with no callbacks. We also handle the utility extensions, HVAC sizing, and the kitchenette layout that makes a garage feel like a studio, not a storage unit with a bed.
New Detached ADU
A new detached ADU gives you the most flexibility - and the most exposure to Palm Springs’s site conditions. The limestone terrain and shallow water table mean standard footings can flood during the rainy season. We design raised slabs or pier foundations that account for groundwater infiltration, and we specify moisture-resistant framing and fasteners that won’t corrode in the humidity that blankets Palm Springs from May through October. Our partnerships with prefab innovators like Abodu, Dvele, Mighty Buildings, and Boxabl give you fast-track options that still meet Palm Beach County’s strict wind-load requirements.
Junior ADU & Interior Conversion
For homeowners who don’t have the lot space or budget for a detached unit, a junior ADU - converting part of your existing footprint into a self-contained living space - can add rental income or multigenerational flexibility. In Palm Springs’s compact 1950s ranches, this often means reconfiguring a wing of the house, adding a small kitchenette, and creating a separate entrance. We handle the structural assessment, the code-compliant separation, and the tie-ins to existing utilities.
ADU Site Prep & Utilities
This is where Palm Springs’s geography gets real. The water table sits high in this low-lying limestone terrain, and any trenching for sewer, water, or electrical service to a detached ADU can hit standing water fast. We’ve developed site prep protocols specific to Palm Springs conditions: dewatering plans, engineered fill for unstable excavations, and corrosion-resistant utility materials that hold up in the persistent humidity. Skip this step, and you’ll be calling us back in two years to re-trench a failed line.
Room Additions & Second Story Additions
Expanding your existing footprint or building up requires structural analysis of your CBS walls and roof-to-wall connections - many of which are unreinforced in Palm Springs’s original housing stock. We assess whether your foundation can handle the load, engineer tie-ins that meet current wind-load standards, and specify materials from our 50+ brand roster that match your existing aesthetic without compromising performance.

You choose the tier that fits your budget; we handle the spec and install.
Common Home Additions & ADU Problems We See in Palm Springs Homes
- Underestimating mandatory wind-mitigation upgrades. Homeowners budget for the ADU or addition, then get hit with a county requirement to replace every jalousie window on the property. We build this into our initial assessment so your financing covers the real scope.
- Footing failures from shallow groundwater. Standard slab pours in Palm Springs’s limestone terrain can heave or flood without proper dewatering and engineered base preparation. We’ve corrected too many failed ADU foundations started by contractors who treated this like inland construction.
- Oversized garage doors with under-specified hardware. Detached workshops and converted garages often have heavier doors than standard residential units. Standard-duty springs and openers corrode and fail quickly in Palm Springs’s humidity. We specify commercial-grade hardware that matches the actual door weight and usage cycle.
- Humidity-accelerated rot in older structures. The CBS construction is solid, but wood trim, fascia, and roof decking in 1950s-70s Palm Springs homes often hides decay. We inspect and replace compromised elements before closing walls, not after the mold appears.

A new detached ADU with full kitchen, impact-rated everything, and extensive site prep on a flood-prone lot pushes toward the top.

FAQs - Home Additions & ADU in Palm Springs
Yes, in nearly every case. Palm Beach County’s wind-mitigation code requires impact-rated or properly protected openings on any home undergoing a permitted addition or ADU project, and original jalousie windows do not meet this standard. We identify this requirement during our initial site assessment and include the replacement scope in your estimate, so you’re not surprised mid-project. Call (844) 665-0162 and we’ll inspect your current windows as part of a free estimate.
We design raised foundations, pier systems, or engineered slabs with integrated drainage that account for groundwater infiltration in Palm Springs’s limestone terrain. Standard footings poured without dewatering and base preparation will heave, crack, or flood. Our site prep includes soil assessment, dewatering protocol, and corrosion-resistant utility installation that prevents the callback cycle we’ve seen from shortcuts.
Yes, if your lot configuration and setback rules allow a partial conversion or an expanded footprint. We design split-use conversions that preserve workshop functionality while adding a kitchenette, bath, and living area that meets Palm Beach County’s residential code. The key is planning the layout before permit submission - retroactive changes add months and thousands to your project.
A garage conversion ADU in Palm Springs typically runs $30,000-$80,000, depending on whether the existing structure needs electrical upgrade, plumbing extension, HVAC addition, and window replacement to meet code. Homes with original jalousie windows and uninsulated slabs trend toward the higher end. We’ll give you a fixed-scope estimate after walking your property - call (844) 665-0162 to schedule.
