AfterFast, Reliable Home Additions & ADU Across Golden Glades
A home addition or detached ADU in Golden Glades generally runs between $45,000 and $130,000 for a standard room addition, while a full ADU construction project typically lands between $90,000 and $220,000. Garage conversions in the neighborhood usually range from $30,000 to $80,000. Those are real numbers for Golden Glades, not national averages, and they account for something most contractors won’t tell you upfront: every permit here routes through Miami-Dade County’s HVHZ plan review, which adds engineering steps and product-approval documentation that you simply don’t face in nearby incorporated cities like North Miami or Opa-locka. Tom Barrett and his sons have been working in this unincorporated Miami-Dade pocket long enough to know exactly what the county reviewers will flag, and we scope for it before you ever sign a contract. If you’re thinking about adding square footage anywhere in Golden Glades, call (877) 610-1318 for a free estimate and we’ll walk the property with you.
Why Barrett & Sons Construction Is Golden Glades’s Preferred Home Additions & ADU Company
We’ve spent nearly three decades running crews across Miami-Dade County, and the work we do in Golden Glades is some of the most code-intensive construction in the state. That’s not marketing talk. It’s what happens when an unincorporated community falls under the High Velocity Hurricane Zone standard, where every structural tie-down, every impact-rated opening, and every roof-to-wall connection has to carry a county product-approval number. Homeowners in Ives Estates, Lake Forest, and the streets off NW 7th Avenue call us because we know the county’s Permitting and Inspection Center process backward, and we don’t treat permits like optional paperwork. The permit inspector works for you, not for me. We make sure the job passes the first time.
Tom Barrett’s name, his address, and his license number are published and verifiable. Look it up before you sign anything. That’s the kind of transparency the 50-to-70 crowd in Golden Glades tells us they’ve been burned for not checking before. Our Home Additions & ADU team is made up of Tom’s sons and crew members who carry the Barrett name on their shirts, not strangers dispatched from an out-of-state call center. A live person answers our phone 24 hours a day, seven days a week, and when you call about a project in Golden Glades, you’re talking to someone who knows what the county will require on your specific block.
Every scope, every allowance, every price change arrives as a written change order before work happens. An allowance that isn’t on paper is a surprise waiting for a date. We back every completed addition and ADU with the 90-Day Done Right Promise, written on the contract. If it’s not done right, Tom comes back and makes it right. One call. That’s the whole promise.
Our Home Additions & ADU Services in Golden Glades
ADU Design & Permitting
Building an accessory dwelling unit in Golden Glades means designing to Miami-Dade’s HVHZ code from the very first drawing, not retrofitting the plans after a county reviewer rejects them. We handle the full permitting package: Notice of Commencement, HVHZ product approvals for every structural component, impact-rated window and door schedules, and coordination with the county’s Permitting and Inspection Center. On a recent detached ADU behind a 1962 CBS block home off NW 7th Avenue near the Golden Glades Interchange, the county flagged the original subfloor attachment and missing load-bearing shear-wall details. We revised the engineering, pulled the Notice of Commencement, and routed everything through the county office with zero rejections on resubmittal.
Garage Conversion ADU
Golden Glades has a deep stock of 1950s through 1970s single-family homes with attached garages that nobody parks in anymore. Converting that garage into a legal ADU in Golden Glades typically runs $30,000 to $80,000, but the county’s HVHZ plan reviewer will not sign off until the existing slab, the wall-to-slab connections, and every opening meet current wind-load standards. Many of these older CBS garages have no hurricane straps and single-pane jalousie windows that can’t pass. We scope the retrofit work at the same time we design the conversion, so the number on your written quote matches the number on the final invoice.
New Detached ADU
A new detached ADU in Golden Glades is a ground-up build on South Florida’s oolitic limestone, where the dry-season water table can sit just a few feet below grade and the wet season can push it to the surface. We set footings deeper than a typical crew would, plan for dewatering during the pour between June and November, and sequence roof tie-downs and hurricane straps before any wall gets closed. Detached ADU construction in Golden Glades runs $90,000 to $220,000 depending on square footage, finishes, and how much site prep your specific lot requires. That range is honest, written, and backed by our change-order rule.
Junior ADU & Interior Conversion
For homeowners who don’t want to pour a new foundation, a junior ADU carved out of an existing floor plan can work inside a Golden Glades home. These interior conversions often mean reworking load-bearing walls in a 60-year-old CBS block house, which is exactly where the county reviewer will ask for engineered shear-wall details and attachment schedules. We handle the structural engineering, the permit package, and the finish work so the space is legal, comfortable, and ready for family or rental income.

Trusted Brands We Service in Golden Glades
When your Golden Glades addition or ADU calls for impact-rated openings, we install windows and doors from PGT, CGI, and Simonton, because those are product lines with full Miami-Dade HVHZ approval numbers already on file. That matters here more than anywhere else in the country. A window without a county NOA (Notice of Acceptance) number gets rejected at plan review, full stop. We stock local parts for Golden Glades jobs and we don’t substitute mystery brands off a van. If we quote PGT, you get PGT. If we quote CGI, you get CGI. Write it in the contract and hold us to it.
Common Home Additions & ADU Problems We See in Golden Glades Homes
- Missing hurricane straps and undersized roof deck fasteners. Most of the pre-1992 CBS block homes in Golden Glades were built before post-Andrew code reforms, and the connections between roof and wall are routinely undersized. County inspectors will not sign off on an addition until the existing structure’s tie-downs are brought current.
- Jalousie and single-pane windows that can’t pass HVHZ product approval. When you add onto an older Golden Glades home, any existing opening that stays in the envelope has to meet current wind-load standards. We scope impact-rated replacements up front so you’re not surprised at inspection time.
- Footing settlement on oolitic limestone with a high water table. Golden Glades sits near sea level on porous rock, and slabs poured without dewatering or percolation planning will settle, crack, or flood during the wet season. We plan the foundation for the water table, not for the dry-season site visit.
- Contractors who assume municipal permitting when it’s county. Golden Glades is unincorporated, which means every permit goes through Miami-Dade County’s Permitting and Inspection Center under HVHZ review. Crews that normally work in incorporated cities get their packages rejected here. We don’t.

FAQs - Home Additions & ADU in Golden Glades
Golden Glades is an unincorporated Miami-Dade County community, so it has no municipal building department of its own. Every addition, ADU, and structural permit routes through the county’s Permitting and Inspection Center under the High Velocity Hurricane Zone code, which is the most stringent wind-load standard in the United States. North Miami and other incorporated cities run their own building offices, but Golden Glades does not. Call (877) 610-1318 and we’ll handle the full county package from Notice of Commencement to final inspection.
The water table in Golden Glades can sit just four feet below grade in the dry season and reach the surface during wet-season rains, which means your footing and slab work likely requires dewatering pumps and careful percolation planning. That adds cost to the foundation phase, and we quote it as a written line item before we dig. Call (877) 610-1318 for a site-specific foundation estimate.
Yes, in nearly every case. Golden Glades’s pre-1992 CBS block homes were built before post-Hurricane Andrew code reforms, so the county reviewer will require engineered roof-to-wall straps, impact-rated openings, and verified shear-wall connections before any second-story framing gets approved. We scope the retrofit at the start so your addition cost includes bringing the existing structure into compliance. Call (877) 610-1318 for a written scope review.
A Notice of Commencement is a recorded legal document filed with Miami-Dade County that formally starts the clock on the construction lien period and identifies the owner, contractor, and property. For any permitted ADU in Golden Glades, the county requires it before the first inspection. We pull it as part of our standard permitting package. Call (877) 610-1318 and we’ll walk you through the paperwork.
No. If your Golden Glades property operates on a septic system, any increase in bedroom count or living space triggers a county health department review of your septic capacity and setback distances. You’ll need documentation that your existing system can handle the added load before the ADU permit advances. We coordinate that review as part of our scope. Call (877) 610-1318 for an exact answer on your specific lot.
