Fast, Reliable Garage Conversion ADU Across Plantation
Garage conversion ADUs in Plantation typically run $185,000-$310,000 all-in, drawings through final inspection, with the final number driven by whether your home sits in a standard subdivision or one of the city’s large-lot areas. If you’re in Jacaranda, Plantation Golf & Country Club corridor, or Plantation Acres, you face a permitting path that most Broward contractors will not flag until it costs you real money. We’re Ellery ADU Studio, and we’ve been designing and building ADUs since 2015, with 900+ permitted under a single contract at a single written price.

Why Ellery ADU Studio Is Plantation’s Preferred Garage Conversion ADU Company
Plantation is not Hollywood, and it is not Davie. The city sits inside Florida’s High Velocity Hurricane Zone, a designation shared only with Miami-Dade and the rest of Broward. That single fact changes the engineering, the window package, the roof connections, and the inspection sequence on every garage conversion we permit here. A contractor who builds ADUs in Palm Beach County will not know that your garage conversion requires product-approved impact windows. We do, because we’ve filed dozens of these permit sets with the City of Plantation, and we’ve stood through the inspections.
Our reputation here rests on what we hand you, not what we tell you. Every Plantation project includes a permit set you can read, a documented photo record from every site visit, and a written scope that locks the price at signing under Haven Standard Clause 1. Nadia Ellery founded this studio on a simple premise: the drawings, the permit set, and the construction should be one contract, so no designer can blame a builder and no builder can blame a designer. In Plantation, where HOA boards and HVHZ inspectors layer extra requirements over city code, that single-contract model is the difference between a project that stalls and one that closes.

Our Garage Conversion ADU Services in Plantation
The housing stock in Plantation was built for a different Florida. Most homes are CBS concrete block ranches from the 1960s through the mid-1980s, and many have carports where a garage would have been. That means a lot of what we do in this city is not a classic garage conversion. It’s a carport enclosure, or a garage partition with a bathroom addition, or an attached garage reinvention. Here’s how each one works in Plantation specifically.
Carport Conversion
In neighborhoods east of University Drive, carports are everywhere. Converting one into a legal ADU in Plantation means meeting HVHZ code for the new exterior walls, which requires impact-rated windows and doors, plus engineered tie-downs at every roof-to-wall connection. A typical carport conversion in Plantation runs $145,000-$210,000. If your carport slab is original, expect a surveyor to verify elevation before we pour anything new, because western Plantation drains toward the Everglades conservation system and many lots carry FEMA flood-zone designations that mandate a higher finished floor.
Garage Partition & Bathroom Add
This is the most common route for Plantation homeowners who still want to park one car inside. We partition the existing two-car garage, build a studio or one-bedroom ADU in the rear section, and add a bathroom with its own plumbing branch. The catch in Plantation is electrical: original panels in these 1960s-to-1980s homes are frequently FPE or Zinsco models that cannot safely support an ADU subpanel. We plan for a full panel replacement in the quote when the panel warrants it, and a typical partition ADU with bath runs $165,000-$240,000 here.
Attached Garage Conversion
An attached garage sitting under the same roofline as the house converts differently in Plantation than it does in non-HVHZ counties. The wall between the former garage and the rest of the house must be brought to current separation standards, and the new living space needs its own rated egress and ventilation. Expect $175,000-$260,000 depending on whether the slab can stay or needs cutting for plumbing. We have converted garages in the Plantation Golf & Country Club corridor where the HOA required specific exterior finishes before the city would even look at the permit.
Detached Garage Conversion
Detached conversions are where Plantation’s larger lots become an advantage. The city’s “City in a Park” master plan produced residential lots that are substantially larger than what you find in Hollywood or Davie, and that extra side yard and rear yard clearance means a detached garage can often be converted without the setback variance that would kill the same project next door in Broward. A detached garage conversion in Plantation runs $190,000-$310,000, with the higher end covering full re-roofs, new sewer connections, and HVHZ-rated replacement windows throughout.

Trusted Brands We Service in Plantation
When a Plantation homeowner wants a prefab or modular path instead of a full site-build, we specify and coordinate systems from Abodu, Cover, and Dvele within the same single contract. That matters here because these units still must meet HVHZ wind-load and impact ratings to pass a Plantation inspection, and we handle the coordination so the factory’s standard spec gets upgraded before it ships. For site-built work, we routinely specify James Hardie siding and trim on garage conversions where the HOA or the city requires a specific aesthetic. We keep our Plantation crews familiar with these systems so the install does not stall on a missing connector or a backordered window package.
Common Garage Conversion ADU Problems We See in Plantation Homes
- Skipping HOA architectural review before filing the city permit. Plantation has dozens of HOA-governed planned subdivisions, and many of them will not allow construction to proceed once city permits are pulled if their own review never happened. On a carport conversion we did in a Jacaranda subdivision, the HOA review added three weeks before the city would accept the application. We now file the HOA package first, as policy.
- Underestimating septic-to-sewer conversion in Plantation Acres. Adding a second dwelling unit on a large lot in Plantation Acres can trigger a county requirement to abandon the existing septic system and connect to municipal sewer. That hook-up runs $15,000-$30,000 depending on distance to the main, and it blindsides homeowners who priced the ADU without a pre-permit utility review. We run that review before we give you a written price.
- Assuming standard windows and connectors will pass. They will not in Plantation. The HVHZ code requires product-approved impact windows and engineered roof-to-wall connectors on any new structure, including an ADU. A cheap quote that omits these will fail inspection and leave you with a non-compliant, potentially uninsurable unit.
- Building on an undersized or aging electrical panel. Original Zinsco and FPE panels are common in Plantation’s ranch housing stock, and neither can safely take an ADU subpanel. We discovered a Zinsco panel on that same Jacaranda carport conversion, and the full panel replacement was written into the scope before we started, not sprung later.

FAQs - Garage Conversion ADU in Plantation
You will face a minimum of three HVHZ-specific inspections in Plantation: a structural inspection verifying roof-to-wall connectors, a product-approval check on all impact windows and doors, and a final HVHZ compliance inspection before the city issues a certificate of occupancy. We have passed all three on our Plantation projects to date, and our permit sets are written to the city’s current HVHZ checklist so there is no ambiguity at inspection time. Call (971) 497-2402 for a written quote that includes the inspection schedule.
Yes, in almost every Plantation HOA-governed subdivision, and the sequence matters. The HOA architectural review comes first, and the city will typically not accept your permit application until the HOA letter is on file. The review can take two to four weeks. We prepare and file the HOA package as step one on any Plantation garage conversion, because waiting until after construction starts is how projects get halted indefinitely.
It may, and this is a $15,000-$30,000 question. Adding a second dwelling unit on a Plantation Acres parcel commonly triggers a county directive to abandon the existing septic system and connect to municipal sewer. The exact requirement depends on your lot, your current tank condition, and your distance to the main. We run a pre-permit utility review on every Plantation Acres quote so this cost appears in writing before you sign anything, not after.
Many Plantation homes built between the 1960s and 1980s still carry original FPE or Zinsco panels, and these panels are known fire hazards that cannot safely accept the additional load of an ADU subpanel. If your panel is one of these, the code will require a full replacement before the ADU electrical can be approved. We include that replacement in your written price when the panel warrants it, so the cost is visible up front, not hidden in a change order.
Every window and door in a new Plantation ADU must carry a Miami-Dade or Florida Building Code product approval for impact resistance, and the roof-to-wall connections must use engineered connectors rated for the HVHZ wind zone. If a garage conversion skips these, the insurance carrier can deny a future wind-damage claim because the structure was built outside code. Our permit sets document every product approval and every connector, and we hand you that documentation at completion. Call (971) 497-2402 for a free estimate, or request a Free Second Opinion if you already have a written quote from another builder. We will review it against Plantation’s actual requirements and show you what is missing.
