Fast, Reliable Garage Conversion ADU Across Boynton Beach
Garage conversion ADUs in Boynton Beach typically run $180,000-$240,000 all-in, from permit drawings through final inspection, with the final number driven almost entirely by three things: your electrical panel’s capacity, whether your lot sits east of I-95 in a FEMA flood zone, and what your HOA’s architectural review committee will actually approve. Call (971) 497-2402 for a written price before any work starts, per Haven Standard Clause 1. We’re the Garage Conversion ADU team that files the permit set, handles the architectural review packet, and builds the unit under one contract, so nobody can point at anyone else when something goes sideways.
Ellery ADU Studio has designed, permitted, and built 900+ ADUs since 2015. Led by Nadia Ellery, the studio coordinates Boynton Beach projects from our Miami (South FL) office, with crews working locally throughout the city. Every project comes with a documented photo record on every visit and the 365-Day Done Right Promise: if the finished ADU is not built to the permitted drawings, we make it right. In writing. Before the project starts.
Why Ellery ADU Studio Is Boynton Beach’s Preferred Garage Conversion ADU Company
Boynton Beach is a harder ADU market than most of Palm Beach County. The housing stock is dominated by 1970s-1990s concrete block stucco (CBS) garages wired to 100-amp panels, and a large share of homeowners live in HOA-governed or age-restricted communities like Century Village. State law changed in 2023, but it did not erase private deed restrictions. We handle both layers: the county’s building code and your association’s architectural review guidelines. That’s the work most contractors skip until the stop-work order arrives.
Our reputation in Boynton Beach comes from documented outcomes, not anecdotes. Every client receives a written scope, a permit set signed by a licensed designer, a photo record of each visit, and a warranty that names what happens if the build deviates from the approved drawings. The studios’ background-checked, uniformed crews carry the license number on every page and every truck. We don’t ask you to trust a promise. We hand you the paperwork that makes it enforceable.
When a Boynton Beach homeowner calls us about a garage conversion, we show up with the trade’s actual vocabulary and explain it in plain terms: the electrical load calculation, the base flood elevation, the lateral sewer connection. Then we tell you what each line item will cost before you sign anything. That’s not a sales tactic. That’s Haven Clause 1, and it’s the reason we’ve completed 900+ ADUs without a single change-order dispute.
Our Garage Conversion ADU Services in Boynton Beach
Attached Garage Conversion
An attached garage conversion is the most common ADU path in Boynton Beach because it works within the existing roofline and foundation. The dominant housing stock makes this an easy structural starting point: single-story CBS construction, slab-on-grade, attached one- or two-car garages. The work is in the mechanical and electrical upgrades, not the framing. We convert the garage into a permitted, habitable unit with its own kitchen, bathroom, and exterior entrance, while making sure the original 100A panel doesn’t try to feed an entire second household.
Detached Garage Conversion
Detached garage conversions in Boynton Beach give you more flexibility on setbacks and floor plan, but they come with their own set of Palm Beach County requirements, especially if the structure falls within a FEMA Special Flood Hazard Area east of I-95 near the Intracoastal. We handle the base flood elevation determination, the stem wall or elevated slab work, and the continuous mechanical ventilation that humidity demands. On lots between 7,500 and 10,000 square feet, a detached conversion can often be paired with a carport replacement so you don’t lose covered parking.
Carport Conversion
Converting a carport to a JADU or studio unit is a smaller lift, but it still requires the same permit set and final inspection. In Boynton Beach, the catch is usually the electrical panel: carport circuits are rarely rated for a dwelling unit. When we do a carport conversion, the first thing we check is the panel’s service rating and the distance to a sewer lateral. Both have to be confirmed before we submit drawings. If a lateral upsizing is required, we file it as part of the same permit package.
Garage Partition & Bathroom Add
Not every homeowner wants a full unit. A garage partition and bathroom add in Boynton Beach lets you carve out a habitable space while keeping storage or a workshop. We run the new plumbing to the closest waste line, add a properly sized exhaust fan for the humidity, and make the partition meet the same fire separation standards as a full conversion. In age-restricted communities like Century Village, this type of modification still requires architectural review because the exterior appearance changes, or because the HOA’s governing documents restrict any structural alteration to the garage’s permitted use.
Garage JADU
A JADU (Junior Accessory Dwelling Unit) is a smaller conversion capped at 500 square feet, typically with an efficiency kitchen and its own entrance. The 2023 Florida HB 1239 mandate opened JADUs on single-family lots across the state, but in Boynton Beach the practical constraint is often the sewer lateral. In the Heart of Boynton CRA, many older CBS homes still rely on original lateral connections to the city sewer system. Those must be inspected and sometimes upsized before the county issues a certificate of occupancy for a second unit. We handle that inspection and the upsizing if needed, inside the same written scope.

Trusted Brands We Service in Boynton Beach
We specify and coordinate prefab and modular systems from brands including Cover, Dvele, and Mighty Buildings within our single design-build contract.

If you’ve already priced a prefab ADU from one of those manufacturers, bring us the written estimate and we’ll give you a Free Second Opinion, including a line-by-line review of what’s included and what’s not. We’ll also tell you how the manufacturer’s system fits Boynton Beach’s wind-load requirements and flood-zone elevation rules before you spend a dollar on a deposit.
Common Garage Conversion ADU Problems We See in Boynton Beach Homes
- 100-amp panels feeding a new kitchen and bathroom. The dominant 1970s-1990s CBS garages in Boynton Beach were built for two cars, a garage door opener, and a couple of outlets. When Palm Beach County’s inspector sees a new ADU kitchen and bathroom running off an undersized panel, the stop-work order follows. We run the electrical load calculation before we submit the permit set, and the panel upgrade to 200 amps is in the written scope from day one.
- HOA architectural review skipped or underestimated. Century Village and other HOA-governed communities in Boynton Beach have private deed restrictions that Florida HB 1239 does not preempt. We file the architectural review packet before demo starts, and we schedule the build around the committee’s meeting calendar so the garage doesn’t sit half-finished waiting on an approval we should have seen coming.
- FEMA flood zone requirements discovered after framing begins. Garages east of I-95 near the Intracoastal fall within Special Flood Hazard Areas. The finished floor has to be raised to base flood elevation, or the certificate of occupancy gets denied. We check the FEMA map before we draw the plans, and we add the stem wall or elevated slab line item in the original quote, not as a door-side surprise.
- Sewer lateral connections too old or too small for a second unit. In the Heart of Boynton CRA and other older neighborhoods, the original lateral connections were sized for a single-family home from the 1970s. A second unit means more waste flow. We have the lateral camera-inspected and the condition documented before the permit application goes in. If an upsizing is needed, it’s in the written scope and the county sees it on the drawings.
Pricing for Garage Conversion ADU in Boynton Beach, FL
A realistic garage conversion ADU in Boynton Beach runs $180,000-$240,000, drawings through final inspection. Here’s the breakdown:
- Attached garage conversion: $180,000-$225,000
- Detached garage conversion: $210,000-$255,000
- Garage partition and bathroom add: $95,000-$145,000
- Garage JADU (under 500 sq ft): $130,000-$175,000
- Electrical panel upgrade to 200A (if needed): $5,000-$9,000
- Slab elevation for flood zone lots (east of I-95): $12,000-$28,000
In Boynton Beach specifically, the two cost variables that change the number fastest are the panel upgrade and the flood-zone elevation. A garage conversion on a 7,500 sq ft lot inland off Hypoluxo Road with a newer 200A panel will land at the lower end. A garage east of I-95 near the Intracoastal with an original 100A Federal Pacific panel and a 4-inch slab below base flood elevation will land higher because the stem wall, the panel, and the mechanical ventilation all stack. Every quote is a written price before any work starts, per Haven Clause 1. Call (971) 497-2402 for your number.

FAQs - Garage Conversion ADU in Boynton Beach
No. Florida HB 1239 preempts local zoning laws that prohibited ADUs, but it does not override private deed restrictions or HOA governing documents. In Boynton Beach, where HOA-governed and age-restricted communities like Century Village are dense, that means your association’s architectural review guidelines still apply. We file the architectural review packet alongside your permit set, and we schedule the build around the committee’s meeting calendar so the approval timeline is predictable rather than a surprise. Call (971) 497-2402 to get a written price and a review strategy for your specific HOA.
Plan for an additional 3 to 6 weeks in Boynton Beach, mostly because the density of HOA-governed communities means more submittal packets are in front of the same committees at any given time. Delray Beach’s single-family neighborhoods tend to have fewer deed-restricted parcels, so the review window is usually shorter. We file the packet before demo, and we don’t start framing until the approval is in hand. That sequencing is part of the written scope, not an afterthought.
Almost certainly yes. A 100-amp panel cannot safely feed a new kitchen and bathroom alongside the existing house load. Palm Beach County inspectors will flag it during the electrical rough-in, and a stop-work order will follow if the load calculation wasn’t updated in the permit set. We run the load calculation before we submit anything, and the 200-amp upgrade (typically $5,000-$9,000) appears in your written quote from day one. No door-side upsells.
If FEMA maps place your garage within a Special Flood Hazard Area, yes. The finished floor has to be raised to base flood elevation, which usually means a stem wall or elevated slab. Our field team recently handled this exact condition on an attached two-car garage in the Heart of Boynton CRA: the original slab was 4 inches below base flood elevation, so we added a 5-inch stem wall and continuous mechanical ventilation with a Panasonic WhisperGreen exhaust fan to keep the unconditioned wall cavities dry. That elevation line item is in the written quote, not discovered mid-build.
You can convert the garage, but the sewer lateral question has to be answered first. Many older CBS homes in the Heart of Boynton CRA still rely on original lateral connections sized for a single-family household. We camera-inspect the lateral before the permit application goes in, and we document the finding in the photo record. If the lateral needs upsizing, it’s part of the same permit package and the same written price. Call (971) 497-2402 for an exact quote, estimates are free.
