Fast, Reliable Home Additions & ADU Across Palm Springs
Home additions and ADU construction in Palm Springs, FL typically run $45,000 to $130,000 for an addition and $90,000 to $220,000 for a new detached ADU, depending on size, finishes, and how much structural retrofit the existing home needs. Every job in this village runs through the Village of Palm Springs building department, not Palm Beach County, and that single fact changes how permits, inspections, and wind-load compliance get handled. We’ve pulled permits here long enough to know exactly what the village inspector checks first. If you’re planning a room addition, second story, or ADU in the 33406 ZIP, call (877) 610-1318 and we’ll walk the property with you before you spend a dime on plans.
Why Barrett & Sons Construction Is Palm Springs’s Preferred Home Additions & ADU Company
Tom Barrett put his name on this company in 1998, and his sons run the crews that work here in Palm Springs. That’s not marketing language. It means the person who shakes your hand at the estimate is the same person who walks the job site, checks the strap pattern, and signs off before the inspector arrives. We don’t dispatch strangers from a call center in another state. The crew members who show up at your door are background-checked, uniformed, and they carry the Barrett name.
Palm Springs homeowners call us because we understand the village’s building department better than contractors who mostly work unincorporated Palm Beach County. The Village of Palm Springs plan review process holds additions and ADUs to a specific wind-load standard, and we file for the right permit the first time. A live person answers our phone 24/7 at (877) 610-1318, so when you have a question about your permit status or a change order, you reach a human being, not a voicemail box.
Our Home Additions & ADU Services in Palm Springs
ADU Design & Permitting
We handle the full permit package for ADUs in Palm Springs, from as-built drawings of your existing CBS home through the Village of Palm Springs plan review and inspection sign-off. A compliant package includes wind-load calculations tied to the 160+ mph design wind zone, impact-rated opening schedules, and a load path that connects the new trusses to the existing masonry. We walk you through every line item before you sign anything.

Garage Conversion ADU
Converting an attached garage into a living unit in Palm Springs means cutting into a CBS block wall, and that’s where older homes show their age. We budget for the structural header, the tie-down retrofit, and the impact windows the village inspector will require. The garage conversion range in this market runs $30,000 to $80,000, and we’ll give you a written scope before the first block gets cut.

New Detached ADU
A new detached ADU on a Palm Springs lot almost always needs a dewatering plan, because the water table in the 33406 flatlands can sit just inches below grade. We work with local soil engineers who know the village’s lot conditions, and we design the slab elevation accordingly. Our Home Additions & ADU team handles everything from clearing to the final certificate of occupancy.

Junior ADU & Interior Conversion
A junior ADU carved out of an existing bedroom or bonus room is often the most cost-effective way to add a rentable unit or an in-law suite in Palm Springs. Because it stays within the existing footprint, it avoids the biggest wind-load triggers, but the village still requires a separate permit and a compliant egress window. We handle the paperwork and the framing in one pass.

Trusted Brands We Service in Palm Springs
We install materials you can look up, not mystery brands off a van. On Palm Springs additions and ADUs we regularly spec Simpson Strong-Tie hardware for the load path, impact-rated window packages from established manufacturers, and when hardscape or driveway work is part of the scope, Belgard and Techo-Bloc pavers. When your quote lists a named product, you can check what it is before you sign. That’s the point. We stock common parts locally so a hardware run doesn’t stall your rough-in inspection.
Common Home Additions & ADU Problems We See in Palm Springs Homes
- Permits pulled from the wrong jurisdiction. A contractor who files with Palm Beach County instead of the Village of Palm Springs gets a stop-work order when the village inspector arrives. We’ve had to unwind several of these for homeowners who called us mid-project.
- Unreinforced bond beams and missing hurricane straps. On a 1960s CBS ranch near Congress Avenue, our crew opened the wall for a second-story addition and found no hurricane straps tying the trusses to the bond beam. The Village of Palm Springs inspector flagged it before we could close rough-in, and the owner’s “simple” addition grew a structural retrofit line item.
- Dewatering costs nobody budgeted. Digging footings for a new detached ADU in Palm Springs means hitting water sometimes just inches down. If your quote doesn’t include a dewatering plan, you’ll find out about it the day the excavator arrives.
- Impact-rated openings left out of the bid. A cheap quote often omits impact windows and rated doors, then the village plan review kicks it back. A compliant quote lists them up front, and that’s the quote that actually gets built.
Pricing for Home Additions & ADU in Palm Springs, FL

A room addition over an existing 1950s CBS home lands higher when the permit triggers a structural retrofit for missing hurricane straps or unreinforced bond beams. A new detached ADU on a lot with a high water table costs more than one on elevated ground, because the dewatering and elevated slab design add real line items. The quote we give you includes every scope, every allowance, and every price change as a written change order before work proceeds. No surprise invoices at the end.

FAQs - Home Additions & ADU in Palm Springs
Palm Springs sits in a 160+ mph design wind zone under current Florida Building Code wind-speed maps, so the village requires impact-rated openings on virtually all new construction and major alterations regardless of distance from the coast. The village plan reviewer will not approve a window schedule without a wind-load rating that matches the new addition’s exposure category. A compliant quote lists the specific impact-rated window package up front. Call (877) 610-1318 and we’ll show you what the village will accept before you buy anything.
It adds a structural retrofit line item that most cheap quotes leave out. On older Palm Springs CBS homes, the trusses were often set on unreinforced bond beams with no engineered connection to the wall system. When the village inspector sees that during a second-story addition permit, the deficiency has to be corrected before the new framing can pass. That typically means adding a continuous Simpson Strong-Tie load path from the trusses down to the foundation, plus those impact-rated windows, before rough-in closes. We found exactly this on a 1960s ranch near Congress Avenue, and the owner’s final cost reflected the retrofit work, not the low bid he’d originally planned around.
Yes, in most cases it can. When the ADU permit closes and the village issues the certificate of occupancy, you have documentation of a wind-compliant structure, impact-rated openings, and a continuous load path. That record is what insurance carriers accept for a wind mitigation credit or a reduction on the new structure’s windstorm premium. An unpermitted ADU or one built without the village’s inspection record gets you none of that, and it can trigger a non-renewal if the carrier discovers it. We leave every Palm Springs ADU owner with the full inspection trail.
The water table in the 33406 flatlands can sit just inches below grade, and you’ll find out the hard way when the excavator starts digging. A dewatering plan keeps the excavation dry long enough to pour a stable slab and prevents the slab from heaving or cracking when the water table rises in the wet season. Some Palm Springs lots need an elevated slab design instead, depending on soil borings. We bring in a local soil engineer before we bid the slab, so the number we give you is the number you pay.
The village permit package includes a plan review by Village of Palm Springs staff who inspect against the village’s own wind-load and structural retrofit standards, not Palm Beach County’s. That means the reviewer will look specifically at the existing structure’s tie-down condition, the impact-rated opening schedule, and the load path for the new work. A county permit skips that local review, and the village inspector will stop the job when he arrives and finds the permit wasn’t filed with the right office. Our quote includes the village permit, the plan review, and every inspection through final sign-off, with each step written into the scope before you sign.
