Fast, Reliable New Detached ADU Across Homestead
A new detached ADU in Homestead typically runs $185,000 to $320,000 all-in, drawings through final inspection, depending on size, site conditions, and whether you go custom or prefab. That’s the range we’ve seen across Homestead’s Redland lots, Keys Gate subdivisions, and the older grid streets near downtown. Ellery ADU Studio designs, permits, and builds the entire project under one contract at one written price. Call (971) 497-2402 to get a written estimate before any work starts.
Homestead is not Miami, and it’s not Kendall. The code requirements here are different, the flood zones are different, and the inspectors check things that contractors from Broward or out of county routinely miss. We know that because we’ve pulled permits and passed inspections on detached ADUs all over Homestead, from agricultural parcels off SW 232nd Ave to standard 50-foot-wide lots near Campbell Drive. This page maps exactly which Miami-Dade NOA product approvals, flood elevation details, and HVHZ inspection steps a Homestead detached ADU must clear before final, so a permit-ready quote doesn’t stall at the same three points where out-of-county builds do.

Why Ellery ADU Studio Is Homestead’s Preferred New Detached ADU Company
Since 2015, Ellery ADU Studio has completed 900+ ADUs across South Florida, every one with a written price before work started and a documented photo record at completion. In Homestead specifically, we’ve seen the full range: casitas on Redland agricultural lots, studio ADUs tucked behind Keys Gate homes, and two-bedroom units on the flood-zone lots east of Krome Avenue. Nadia Ellery, our founder and principal, sets the standard on every project: the permit set is the product, not an afterthought.
Our crews serving Homestead are background-checked and uniformed. The license number appears on every page, verified, not just claimed. We work directly with Miami-Dade building inspectors, and we’ve built working relationships with the plan reviewers who handle HVHZ submittals. That matters in Homestead because a plan reviewer who knows your firm’s drawing conventions is less likely to bounce a submittal over a missing wind-load detail.
You’ll get a written price before work starts, per Haven Standard Clause 1. No “call for a quote” theater. The scope is locked at signing under Clause 5, so there’s no door-side upsell when the inspector requires a change. And if the finished ADU isn’t built to the permitted drawings, the 365-Day Done Right Promise applies, in writing, before the project starts.
Our New Detached ADU Services in Homestead
Custom Built ADU
A custom detached ADU in Homestead means we design around your lot’s actual constraints: setbacks from the property line, flood elevation requirements, and the HVHZ wind loads that dictate your wall assembly and roof tie-downs. On larger Redland lots, we often design casitas with covered porches and detached storage that a prefab module can’t deliver. The drawings are yours, the permit set is ours to produce, and construction is the same contract.
Prefab ADU Installation
Homestead’s HVHZ code doesn’t disqualify prefab, but it does require every module to submit Miami-Dade product approvals for the wall panels, the truss connections, and the anchoring system. We coordinate factory-built units from brands like Abodu, Cover, and Dvele within the same single contract. We’ve seen enough out-of-state modules arrive with truss tie-downs that don’t submit HVHZ approvals; we catch that in the submittal phase, not at the panel mount.
Modular ADU
Modular construction in Homestead has to clear the same NOA and wind-load hurdles as site-built framing, which is why we specify systems with active Miami-Dade approvals before the factory starts cutting. Mighty Buildings panels, for instance, carry HVHZ documentation, which speeds the plan review on flood-zone lots where every week of delay costs carrying time. We handle the factory coordination, the foundation details, and the final inspection.
Studio ADU
A studio ADU in Homestead, typically 400 to 600 square feet, is the most popular entry point for a rental unit or an in-law suite. The cost runs about $185,000 to $230,000 when the lot is dry and the existing electrical panel has capacity. On flood-zone lots, the raised slab becomes a bigger line item, which we quote explicitly rather than burying in a vague “site work” allowance. We build studios on standard city lots and on the oversized agricultural parcels along the Redland corridor.

Trusted Brands We Service in Homestead
We specify and coordinate prefab and modular systems from Abodu, Cover, Dvele, and Mighty Buildings, among others, within the same single contract. For Homestead customers, that means the brand selection isn’t a separate procurement headache; it’s a line item in the written quote with a named factory, a named module, and a named delivery date. We coordinate the factory submittals, the local foundation, the crane or panel lift, and the final trim and inspection. Our team knows which of these brands carry current Miami-Dade NOA approvals, and we don’t spec a system that can’t clear Homestead’s hvhz and HVHZ reviewers.
Common New Detached ADU Problems We See in Homestead Homes
- Non-NOA products flagged at frame inspection. A contractor installs a Florida-approved impact window that lacks a Miami-Dade Notice of Acceptance number. The Homestead field inspector red-tags the opening, the window comes out, and the owner eats the cost. We pull NOAs before rough-in, every time.
- Out-of-state prefab tie-downs rejected. A factory-built ADU arrives with truss or wall tie-downs approved in Texas or California but not submitted to Miami-Dade HVHZ. The panel sits on the ground while the engineer re-draws the connection. That’s a multi-week delay we prevent at submittal.
- Slab built at existing grade on a flood-zone lot. The owner wants to save money, builds the ADU floor at grade, and FEMA letters hold up the certificate of occupancy until the slab is raised or dry-floodproofed. On Homestead lots in Special Flood Hazard Areas, the finished floor often needs to sit 2 to 3 feet above base flood elevation. We quote that explicitly.
- Vapor barrier and drainage skimped. Homestead’s humidity and tropical rainfall punish any detached structure without a proper vapor barrier and drainage plane. We see low bids that drop the barrier or the elevation, and the owner discovers it as mildew and slab moisture a year later. This is not a place to cut.
Pricing for New Detached ADU in Homestead, FL
A custom detached ADU in Homestead runs roughly $210,000 to $320,000, drawings through final inspection. A studio ADU lands between $185,000 and $230,000. A prefab or modular unit, depending on brand and size, falls between $190,000 and $270,000 installed on a Homestead foundation. The numbers shift with soil conditions, flood-zone requirements, panel capacity, and the finish level you choose. A raised slab on a flood-zone lot can add $18,000 to $35,000 compared to a standard slab on a dry lot. What affects cost most in Homestead is the elevation and the NOA compliance, and a cheap quote that skips either will stall at inspection. Call (971) 497-2402 for a written, line-item price before any work starts.

FAQs - New Detached ADU in Homestead
Yes, every window and door on a new detached ADU in Homestead must carry an active Miami-Dade Notice of Acceptance number. Homestead sits inside the High Velocity Hurricane Zone, the most stringent wind-resistance jurisdiction in the continental US. A Florida statewide product approval without a Miami-Dade NOA fails inspection when the inspector pulls the number on-site. That’s the trap that catches out-of-county contractors regularly, and it’s a fixable but expensive mistake. Call (971) 497-2402 for an exact quote; estimates are free.
A new detached ADU in Homestead must be engineered to 175 mph or higher wind loads, per Miami-Dade HVHZ requirements. That applies to the roof, the wall assemblies, the anchoring, and every opening. The permit set we produce includes the wind-load calculations and the product approvals, so the plan reviewer sees a complete submittal, not a revision request. Call (971) 497-2402 to get a written estimate.
Raising the slab above base flood elevation typically adds $18,000 to $35,000 to a Homestead ADU project, depending on the fill, the stem wall height, and the compaction. It also changes the approval path: the finished floor elevation must clear FEMA’s BFE before the final certificate of occupancy is issued. On flood-zone lots, we quote the raised slab as an explicit line item, not a vague site-work allowance. Call (971) 497-2402 for a written line-item quote.
Beyond the Miami-Dade building permit, a new Homestead ADU typically needs the product approval submittals (Miami-Dade NOA numbers for windows, doors, and roofing), a flood-zone elevation certificate if the lot is in a Special Flood Hazard Area, and the wind-load calculations for the structure. We assemble all of that as part of the permit set, so the first inspection doesn’t stall on missing paperwork. Call (971) 497-2402 to review your lot’s specific requirements.
An ADU built to HVHZ standards, with raised slab and NOA-rated openings, can qualify the main house for wind mitigation credits, which typically reduce the wind premium on the policy. On a Redland agricultural lot off SW 232nd Ave, our crew framed a new detached casita while the owner was still deciding between a prefab and custom build; we pulled NOAs for every impact window and door before rough-in because the inspector checks those numbers before he’ll even glance at the strap ties. The job passed final after we raised the finished floor to 2.5 feet above base flood elevation to clear the FEMA BFE, which also means the owner’s wind mitigation credits locked in lower insurance premiums from day one. Call (971) 497-2402 to discuss your lot’s insurance implications.
