AfterFast, Reliable Home Additions & ADU Across Homestead
Home additions and ADU construction in Homestead run $45,000 to $130,000 for additions and $90,000 to $220,000 for a new detached ADU, with garage conversions landing between $30,000 and $80,000. Those numbers get real fast once Miami-Dade’s High-Velocity Hurricane Zone code requirements enter the picture, and that’s where most Homestead homeowners either save money or lose it. We’re Barrett & Sons Construction, Tom Barrett’s crew, and we’ve been building and remodeling in Homestead long enough to know which window carries the right HVHZ Notice of Acceptance before the inspector walks up the driveway. Call (877) 610-1318 and we’ll scope your project in writing, permits included.
Why Barrett & Sons Construction Is Homestead’s Preferred Home Additions & ADU Company
We’re not a franchise. Tom Barrett started this company in 1998, and his sons run the crews. When you call the Homestead number, a live person answers, not an out-of-state call center. When we say we’ll be at your house in the 33033 corridor on Tuesday morning, the person who shows up carries the Barrett name on his shirt and knows the difference between a statewide Florida NOA and the Miami-Dade HVHZ NOA your inspector will actually accept.
Homestead homeowners have been burned before. The story we hear most often is a bid from a company that quoted one price over the phone and handed over a different bill after the permit review caught non-compliant windows. Our quotes itemize HVHZ-rated materials up front, because that’s the only number worth reading in this city. Every scope, every allowance, every change order arrives on paper before the work moves. And every job carries the 90-Day Done Right Promise: if it’s not done right, Tom comes back. One call.
You can look up Tom Barrett’s name, address, and license number yourself. We like it when you do. The permit inspector works for you, not for me. That’s why we pull permits and sign inspections on every eligible Homestead job: additions, ADUs, sunrooms, garage conversions, the whole list.
Our Home Additions & ADU Services in Homestead
ADU Design & Permitting
An ADU in Homestead is not a shed with drywall. Because we sit at the southern tip of the Florida peninsula in one of the highest design-wind-speed zones in the continental U.S., every window, door, and roof assembly on that unit must carry a Miami-Dade County Notice of Acceptance issued specifically under HVHZ criteria. We handle the design, the NOA paperwork, the drainage plan, and the permit package as one scope. The inspector’s questions get answered before he asks them.
New Detached ADU
Building a detached ADU in Homestead means working with flat Miami Limestone bedrock that often sits inches below the surface. Deep foundations aren’t always an option, and shallow CBS footings crack under added load if the rebar condition hasn’t been checked. We engineer from the soil up, and we stage the slab work around the May-October wet season so your pour doesn’t turn into a swimming pool. A new detached ADU in Homestead runs $90,000 to $220,000, depending on size, finish level, and whether you want a full kitchen or a kitchenette.
Garage Conversion ADU
Converting a Homestead garage into an ADU is the fastest path to rental income or a mother-in-law suite, but the existing footprint often predates current HVHZ window and door requirements. Most 1993-2005 CBS garages in the 33030 and 33033 corridors have single-pane sliders with no impact rating at all. We replace them with PGT or CGI impact-rated units carrying the Miami-Dade HVHZ NOA, then reframe, insulate, and finish to code. Garage conversions in Homestead run $30,000 to $80,000.
Junior ADU & Interior Conversion
A junior ADU built inside your existing Homestead home is the most budget-conscious option, typically under $45,000 depending on plumbing. You’re dividing your existing footprint rather than adding square footage, which simplifies the permit path. But you’ll still need HVHZ-mandated inspections for any new windows or exterior door openings, and we handle those as part of the scope. It’s an in-law suite, a rental, or just breathing room without pouring new footings.

Trusted Brands We Service in Homestead
We install Simonton, PGT, and CGI impact-rated windows and doors across Homestead, because those lines all carry the Miami-Dade HVHZ product approvals your inspector needs to see. When a window arrives with only a standard statewide NOA, the county rejects it, and you pay for the re-order plus the schedule delay. We keep the common HVHZ-rated sizes and NOA paperwork moving for Homestead projects so that cost never lands on you twice.
Common Home Additions & ADU Problems We See in Homestead Homes
- Rejected windows and doors at HVHZ inspection. Products with a standard Florida NOA, commonly accepted in Monroe or Broward counties, fail in Homestead. The inspector flags it, and you’re paying for a re-order and an extra week of schedule.
- Load-bearing walls sitting on tired CBS footings. The flat Miami Limestone bedrock and shallow footings common across Homestead crack when you add a second story without checking rebar condition first. We core-sample before we frame.
- Standing water on ADU sites during the wet season. Starting a detached ADU without an approved drainage plan means your slab pour waits on the rain. In Homestead, the May-October wet season doesn’t care about your schedule.
- Pre-Andrew wood-frame surprises in the older downtown core. A pocket of pre-1992 wood-frame housing still stands near downtown Homestead and in agricultural-worker neighborhoods. Those structures carry different structural and code-compliance needs than post-Andrew CBS stock.

FAQs - Home Additions & ADU in Homestead
Every window and exterior door on a Homestead ADU must carry a Miami-Dade County Notice of Acceptance issued specifically under High-Velocity Hurricane Zone criteria, not just a standard Florida statewide NOA. The county maintains a searchable NOA database, and your inspector will match each product to its approval before sign-off. If the paperwork doesn’t match, the product gets rejected. Call (877) 610-1318 and we’ll spec the right units from the start.
Roof assemblies on Homestead additions need HVHZ NOAs too. That covers the roof deck, underlayment, and the specific shingle or metal system you choose, and the county verifies each layer against its approval during the roof inspection. A roof with a statewide NOA but no HVHZ approval fails. We spec GAF and CertainTeed assemblies with current Miami-Dade HVHZ paperwork on every addition we build here.
Documented HVHZ compliance gives your insurer proof that the addition was built and inspected to the strictest wind-resistance standard in the continental U.S., which can support premium discounts and is essential evidence in a post-storm claim. Without the paper trail, an insurance adjuster cannot verify construction quality after the fact. We hand you every NOA number, permit, and signed inspection report at close-out. Call (877) 610-1318 for a free estimate on a compliant addition.
Because the permit reviewer flagged windows, doors, or roof materials that lacked the Miami-Dade HVHZ NOA, forcing a switch to impact-rated products that cost more and a schedule delay while the supplier re-shipped them. That is the most common reason Homestead ADU quotes climb after submittal. Our quotes include HVHZ-rated product line items from day one, so the number you sign is the number you pay, with any change order in writing before work moves.
Miami-Dade County allows homeowner-builder permits in some cases, but on an ADU with HVHZ product approvals, drainage plans, and structural tie-down requirements, the risk of a failed inspection or rejected material is high. On a 1998 CBS home in the 33033 corridor, we converted an enclosed patio into a permitted sunroom addition. The original sliding glass doors had a statewide NOA but no Miami-Dade HVHZ approval. Our inspector flagged it immediately. We re-ordered a Kolbe impact-rated unit with the HVHZ NOA, completed the beam and subfloor tie-downs per the county’s 2020 revision, and the client’s final inspection cleared the same week. The paperwork made that possible. Call (877) 610-1318 if you’d rather skip the re-orders.
What Homestead Homeowners Need to Know About HVHZ Compliance
Here’s the part most Home Additions & ADU pages never cover. Homestead is unique because Hurricane Andrew in August 1992 destroyed roughly 90% of its built environment. The city rebuilt almost entirely between 1993 and 2005, and that post-disaster housing stock is now aging into its first major renovation and expansion cycle at 25 to 30 years old. Every permitted addition or ADU project on those homes must satisfy Miami-Dade County’s High-Velocity Hurricane Zone Product Approval requirements, the strictest wind-resistance standards in the continental U.S. That’s a direct legacy of Andrew’s destruction, and it’s enforced at a level you won’t find in Monroe or Broward counties, even though they’re just down the road.
What this means for your Homestead project is practical. Before we frame a single wall on your room addition or detached ADU, you need a window and door package with Miami-Dade HVHZ NOAs. You need a roof assembly with the same. You need a drainage plan that keeps your slab pour on schedule through the wet season. And you need a contractor who knows the difference between a statewide NOA and the HVHZ NOA your inspector will actually check. The allowance that isn’t on paper is a surprise waiting for a date. We put it all on paper, with permits pulled and inspections signed, and we back it with the 90-Day Done Right Promise.
If you’re hiring for an Homestead addition or ADU, ask two questions before you sign anything: “Which HVHZ NOA numbers are in the quote?” and “What does the change order process look like?” A straight answer on both tells you more than any review count. Then call (877) 610-1318 for your free estimate. Senior and veteran homeowners save 10%, and a second opinion on any written estimate is always free.
