AfterFast, Reliable Home Additions & ADU Across Delray Beach
Adding square footage in Delray Beach means dealing with two very different sets of rules depending on which side of I-95 you live on, and most homeowners don’t discover that until the permit review stalls. A home addition or ADU in the western communities around Kings Point and Century Village follows a different playbook than a detached unit east of Federal Highway near the barrier island. Barrett & Sons Construction has navigated both sides of that line since 1998. If you’re weighing a garage conversion, a second-story addition, or a detached ADU in Delray Beach, call (877) 610-1318 and Tom Barrett will walk you through what your specific neighborhood actually requires before you spend a dollar on drawings.
Why Barrett & Sons Construction Is Delray Beach’s Preferred Home Additions & ADU Company
Tom Barrett lives twenty minutes from most Delray Beach job sites, and his sons run the crews themselves. When you call about an addition on a 1980s CBS home off Hagen Ranch Road, the person answering the phone understands that block’s setbacks and which structural engineer has already worked with the county on similar floor plans. That matters more than most contractors admit.
We publish Tom’s name, his address, and his license number. Look any of it up before you sign. We also put the 90-Day Done Right Promise on every contract in plain English: if a wall isn’t square, a door doesn’t latch, or a permit detail got missed, one call brings Tom back. No fine print, no phone tree, no out-of-state call center trying to route your complaint.
Every change order in Delray Beach arrives in writing before work proceeds. If the scope changes when we open a wall or hit groundwater during a slab pour, you’ll see the price adjustment on paper first. The allowance that isn’t on paper is a surprise waiting for a date, and surprises are not part of our process.
Delray Beach customers tend to call us after a previous contractor told them permits were optional. They weren’t. The permit inspector works for you, not for me, and we pull every permit and get every inspection signed on eligible projects because that’s the only way to protect the money you’re putting into your property.
Our Home Additions & ADU Services in Delray Beach
ADU Design & Permitting
Accessory dwelling units in Delray Beach trigger a specific set of city and county reviews, and the teardown cycle on the barrier island has made plan reviewers more rigorous than they were even five years ago. We coordinate the architectural drawings, the wind-load engineering, and the permit submission as one package so you’re not paying a designer and a contractor to point fingers at each other. Whether you’re planning a 500-square-foot unit behind a mid-century ranch in 33483 or an attached conversion off a CBS original in 33446, the design stage is where Delray Beach projects win or lose time.
Garage Conversion ADU
Converting a garage in Delray Beach is usually the fastest path to a rentable or family unit, but the existing slab often wasn’t poured to current elevation standards, and the water table in the western ZIPs sits 18 to 24 inches below grade. That means drainage and moisture mitigation happen before framing, not after you notice the baseboards wicking. We’ve converted garages in Kings Point, Century Village, and the 33447 corridor, and we know which existing CMU walls can take a second story and which ones need engineered reinforcement first.
New Detached ADU
A new detached unit on a Delray Beach lot gives you full control over the floor plan, but it also puts you inside the city’s setback rules and the county’s wind code at the same time. If your property falls near a coastal location, the Florida DEP’s Coastal Construction Control Line can add a state review layer that extends timelines by four to eight weeks and raises the engineering bar for foundation and elevation. We plan for that from day one by pre-coordinating with a wind-load engineer before the permit package goes in, which saves you the costly revision loop that hits contractors who try to figure it out mid-review.
Junior ADU & Interior Conversion
Adding a junior ADU inside the footprint of an existing Delray Beach home gets you square footage without the setback fights that come with new construction. This is a common choice in the 1980s and 1990s CBS homes across the 33446 and 33484 ZIPs, where existing interior space can carry a kitchenette, a separate entrance, and a bathroom without triggering the full new-build permitting path. We’ve done enough of these to tell you honestly what can be billed as an ADU versus what the county will treat as a remodel, and that distinction changes your tax picture.

Trusted Brands We Service in Delray Beach
We carry premium brands across every trade, and we stock the local parts Delray Beach jobs actually use. When your ADU needs a paver approach or a hardscape transition from the existing driveway, you’ll see Belgard, Techo-Bloc, and Cambridge Pavers on the materials list, not mystery products off a van. We use Quikrete and Oldcastle products on smaller concrete and masonry work because they hold up to South Florida’s heat and humidity cycles better than the bargain mixes. You can look up every brand we install and verify the warranty yourself, which is the point.
Common Home Additions & ADU Problems We See in Delray Beach Homes
- Groundwater surprises during slab work. In the western ZIPs around 33446 and 33447, the water table sits close enough to the surface that any new footing or utility trench routinely hits groundwater. Contractors from inland markets underestimate the dewatering and drainage costs, then hand the homeowner a change order they should have seen coming. We account for it up front.
- Wind-code redesigns after plan review. Palm Beach County’s 160 to 170 mph design wind speed requirements catch a surprising number of contractors mid-permit, especially on larger additions and new detached units. We’ve seen projects stall for months because a designer submitted structural plans that failed county review on wind load. We coordinate engineering first.
- Barrier-island setbacks and elevation rules. If you’re adding onto a mid-century masonry ranch in 33483, you’re potentially inside the Coastal Construction Control Line, which changes finished floor elevations and foundation requirements in ways that surprise homeowners who’ve only built inland. Mentioning that to a contractor before you pay for drawings is cheaper than discovering it during permitting.
- The teardown pressure on older barrier-island homes. A lot of Delray Beach homeowners call us intending to add a second story to a 1960s ranch, then realize the existing block structure won’t carry the load without major reinforcement. Sometimes the math favors a garage conversion or a first-floor addition instead. We’ll tell you the truth on the first visit, not after the checks clear.
Pricing for Home Additions & ADU in Delray Beach, FL
A home addition in Delray Beach typically runs $45,000 to $130,000 depending on scope, foundation work, and whether the site triggers coastal or groundwater conditions. A full detached ADU construction falls in the $90,000 to $220,000 range. A garage conversion ADU sits between $30,000 and $80,000. Those numbers reflect real Delray Beach labor and materials, not national averages. The water table in the western ZIPs, the wind-zone engineering on the east side, and the age of the existing structure all move the final number. We give you a written line-item estimate before you commit, and every change order comes on paper. Call (877) 610-1318 to schedule a free estimate at your property.

FAQs - Home Additions & ADU in Delray Beach
Most Delray Beach additions and ADUs start with a design and permitting phase that takes two to six weeks depending on coastal reviews and structural plan check, followed by a build phase that varies by project size. A garage conversion typically moves faster than a new detached unit. Call (877) 610-1318 and Tom will give you an honest timeline for your specific street and ZIP, not a generic answer.
Yes. We work across 33447, 33448, 33482, and 33483, including Kings Point, Century Village, the Atlantic Avenue corridor areas, and the barrier island. Some neighborhoods require extra coordination with homeowner or community associations, and we handle that paperwork as part of the permit process.
For structural or water intrusion issues tied to an existing addition or ADU, call (877) 610-1318 and a live person answers 24/7. We’ll schedule a site visit and put any immediate scope in writing before work starts. For planned additions and new builds, we’ll get you on the calendar at the next available slot and keep the schedule honest.
Delray Beach pricing tends to run slightly higher than inland Boynton Beach or Kings Point for two reasons: the barrier-island and coastal-review requirements add engineering and permitting costs, and the western water-table conditions drive up foundation and drainage work. You’re seeing a home addition range of $45,000 to $130,000 and an ADU construction range of $90,000 to $220,000 for Delray Beach specifically. Those are local numbers, not national ones.
