New Detached ADU in Plantation - Plans, Permits & Build, One Fixed Price

Fast, Reliable New Detached ADU Across Plantation

A new detached ADU in Plantation typically runs $180,000-$310,000 all-in, drawings through final inspection, depending on size, site conditions, and whether your property falls in an HOA-governed subdivision. For most Plantation homeowners, the first real hurdle is not the city permit or the construction itself. It is the architectural review board, which governs what materials, colors, roof pitches, and heights get approved before the city will even look at your permit application. If you have been researching a New Detached ADU and found yourself staring at HOA covenants, we can help. Call (971) 497-2402 and we will walk you through the full Plantation sequence, including the review packet your committee will actually sign.

We serve Plantation neighborhoods including Jacaranda, the Golf & Country Club corridor, Plantation Acres, and the larger lots west of University Drive. Nadia Ellery has a particular focus on making sure the architectural review packet is not the thing that derails your schedule.

Why Ellery ADU Studio Knows Plantation’s New Detached ADU Process

Most design-build firms in South Florida treat Plantation like it is Fort Lauderdale with nicer landscaping. It is not. Plantation’s “City in a Park” master plan produced residential lots substantially larger than those in neighboring Broward cities like Hollywood or Davie, which means a detached rear-yard ADU is often physically feasible. But the planned subdivisions that make up so much of Plantation, from Jacaranda to the golf-course corridor, layer private architectural-review committees on top of the city’s own zoning review. That is a separate approval with separate submission requirements, separate meeting dates, and separate reasons to reject.

We learned the hard way what gets an ADU packet rejected in Plantation: the wrong Hardie panel color against a CBS ranch’s existing masonry, a roof pitch that reads too modern for a subdivision of 1970s single-story homes, window trim that matches nothing else on the street. So we built our Plantation process around the committee: we draft the design to the covenants first, we submit the packet ourselves, and we track the review calendar while the foundation and utility work moves forward on the parts of the job that do not require architectural sign-off. The whole point of a one-contract design-build studio is that the same team that draws the elevations also answers when the committee asks why the roofline is 18 feet, not 16. There is no designer to blame, no builder to point at. It is us, under one written price.

We have designed, permitted, and built ADUs across South Florida since 2015. Every project is governed by The Haven Standard: a written price before any work starts (Clause 1), a documented photo record on every visit, and a 365-Day Done Right Promise in writing. Nadia Ellery signs off on every permit set personally. A live person answers (971) 497-2402 when you call.

Our New Detached ADU Services in Plantation

Custom Built ADU in Plantation

A custom detached ADU on a Plantation lot is a real construction project, not a kit drop. We are talking a new foundation, new electrical service, new roof structure designed to HVHZ wind-load standards, and a finished interior with its own HVAC. In Plantation, the custom route is where architectural review matters most, because the committee sees an entirely new structure and will scrutinize its relationship to the main house. We handle that. Our custom ADUs in Plantation generally run $220,000-$310,000 for a 1-bed or 2-bed unit with a kitchen and laundry, finished floors, impact-rated windows, and a full permit set that carries our 365-Day Done Right Promise. Under The Haven Standard, that price is written before drawings start, not after you have committed emotionally to a design.

Prefab ADU Installation in Plantation

Plantation homeowners often assume a prefab unit sails through review because the factory already engineered it. That assumption is expensive. The prefab manufacturer’s engineering does not satisfy Plantation’s architectural review committee, which cares about how the unit looks from the street and from the neighbor’s yard, not how cleverly the modules were fabricated. We specify and coordinate prefab systems including Abodu, Cover, and Dvele within our single contract. That means we are the ones who prepare the elevation drawings, color boards, and roof profiles the committee wants to see, and we are the ones who file the packet. Prefab installation in Plantation, including site prep, foundation, utility hookups, and assembly, typically runs $160,000-$240,000 depending on the unit and the lot. The written price covers everything, set before the factory order is placed.

Modular ADU in Plantation

Modular ADUs sit between full custom builds and prefab panels. The modules are built off-site to a specific set of engineering drawings, then assembled on your Plantation lot. The challenge in Plantation is the same as with prefab: the committee wants to see what the thing will look like, and off-the-shelf modular elevations often read as out-of-place next to a CBS ranch. We have worked with modular systems from Mighty Buildings and others, and we prepare the architectural submittal so the committee sees colors and rooflines matched to your existing home. Modular ADUs in Plantation typically run $190,000-$280,000 all-in. You get the written price before the factory line starts, under Clause 1 of The Haven Standard.

Studio ADU in Plantation

A studio ADU is the smallest detached option, usually 400-600 square feet, one open living space with a kitchenette and a full bath. In a city like Plantation, where many backyards are genuinely large by Broward standards, a studio ADU often makes the most sense for older CBS ranches that have the rear-yard space but not the budget for a full two-bedroom. Studio ADUs in Plantation typically run $150,000-$210,000 complete. The architectural review committee still wants the same package, and we still file it for you, usually with a simpler elevation set because the structure is smaller. Even a studio ADU in a western Plantation flood-zone lot requires the finished floor elevation to clear FEMA’s minimum, which is a survey question, not a slab thickness question.

For larger lots in Plantation Acres and similar zoned areas, a 1-bed or 2-bed detached ADU is often the better long-term asset. A 2-bed detached ADU there runs $230,000-$310,000 depending on foundation work and utility routing. The same rules apply: written price before work, one contract, one team accountable.

Trusted Brands We Service in Plantation

We do not manufacture the panels or modules, we specify and coordinate them under our own permit set and our own written warranty. For Plantation clients we work regularly with Abodu, Cover, Dvele, and Mighty Buildings systems. We stock the common connection hardware, flashing profiles, and HVHZ-rated anchor components locally, so when a module arrives from the factory, the crew is not standing around waiting on a bracket. If you are weighing a prefab path, call (971) 497-2402 and we will tell you honestly which brand’s structural system makes sense for your specific Plantation lot, and which one will fight your HOA’s roofline requirements.

Common New Detached ADU Problems We See in Plantation Homes

• HOA architectural rejection after the fact. Homeowners file the city permit first, the committee later finds out, and the stop-work lands while the roofline or paint scheme gets redesigned. We submit the review packet first, so the permit set already matches what the committee signed.
• The septic-to-sewer trigger nobody priced. In Plantation Acres and other large-lot sections, adding a second dwelling unit can trigger a county requirement to abandon the existing septic and connect to municipal sewer. That hook-up has run $15,000-$30,000 on jobs we have seen, depending on distance to the main. We run a pre-permit utility review before the written price is set so that number is in the budget, not a surprise.
• HVHZ inspection failure on a “standard” slab. Much of western Plantation drains toward the Everglades conservation system, and many neighborhoods carry FEMA flood-zone designations. If the finished floor sits below the required elevation, the inspection fails and you are paying for re-engineering. We survey and engineer the floor elevation before we pour.
• Original panels that cannot carry an ADU subpanel. Many CBS-era Plantation homes still have FPE or Zinsco electrical panels. Adding an ADU subpanel means full panel replacement first. We document what is in the wall before the price is locked, so the panel replacement is in the written quote, not an add-on at rough-in.
