Fast, Reliable Home Additions & ADU Across Gladeview
Home additions in Gladeview typically run $45,000-$130,000 for a room addition, while a full ADU construction project lands between $90,000 and $220,000. The wide gap comes down to scope, and in Gladeview specifically, how much of the existing 1950s-1970s CBS structure has to be brought up to Miami-Dade’s High-Velocity Hurricane Zone code before the new square footage can even be tied in. Most homeowners we meet in the 33147 zip code aren’t shopping for the cheapest bid. They’re looking for a contractor who understands county permitting, knows what the inspector will flag on a jalousie-window house, and writes every allowance down on paper before a hammer swings. That’s how Tom Barrett has run Home Additions & ADU work in this unincorporated pocket of Miami-Dade since day one.
If you’re planning an addition or an ADU in Gladeview, call (877) 610-1318 and we’ll come out, look at what you have, and give you a written line-item estimate. No trip charge inside the county.
Why Barrett & Sons Construction Is Gladeview’s Preferred Home Additions & ADU Company
Tom Barrett founded this company in 1998, and his sons run the crews. That matters in a place like Gladeview, where homeowners have been burned before by outfits that quote one number over the phone and show up with a change order thicker than the original contract. We don’t work that way. Every scope item, every allowance, every price adjustment arrives as a written change order before work proceeds. If it isn’t on paper, it doesn’t exist, and you won’t see it on your final invoice.
Gladeview is unincorporated, which means permits don’t go through a city hall counter. They queue through Miami-Dade County’s central permitting office. Our team has spent nearly three decades working that system, and we know which inspections get scheduled when, where the bottlenecks sit during the summer building rush, and how to keep a project moving instead of stalling. That’s local knowledge you can’t buy from a national chain.
We also make ourselves easy to check. Tom Barrett publishes his name, his address, and his license number. You can look it up before you sign anything, which is exactly what we think you should do. A live person answers our phone 24 hours a day, seven days a week, not an out-of-state call center.
Our Home Additions & ADU Services in Gladeview
ADU Design & Permitting
Because Gladeview sits in Miami-Dade’s High-Velocity Hurricane Zone, an ADU here isn’t a stock plan pulled off a shelf. The county requires rated impact glazing, impact windows and doors that meet HVHZ standards, engineered roof-to-wall connections, and third-party inspections on structural and electrical work. We handle the full design package, the county submission, and every inspection from footing to final. If you’ve heard from a previous contractor that permits are optional, that’s a red flag you don’t want to ignore, especially in an unincorporated area where the county enforcement unit actively audits jobsites.

Garage Conversion ADU
Most garages in Gladeview were built in the 1960s and 1970s as open concrete block shells, never intended for habitation. Converting one into an ADU means adding proper insulation, impact windows, a finished floor assembly, and often a new electrical subpanel - the same roofing and structural protections we build into every Gladeview project. A garage conversion in Gladeview typically falls between $30,000 and $80,000 depending on whether the existing slab is sound and how much plumbing has to be trenched through Miami Limestone.

New Detached ADU
A new detached ADU in Gladeview gives you a clean slate, which is often easier than retrofitting an older structure, but it comes with the full weight of HVHZ code from the first footing pour. Expect $90,000 to $220,000 for a permitted, inspected unit with its own utility connections. The water table rises sharply during the June-to-October wet season, so footings and any below-grade drainage rough-ins have to be scheduled carefully, often with dewatering on-site.

Junior ADU & Interior Conversion
For homes with an existing oversized laundry room, a closed-in carport, or a spare bedroom wing, a junior ADU or interior conversion can make sense. These projects typically run on the lower end of the $45,000-$130,000 addition range. The catch is that even an interior conversion in Gladeview triggers window upgrades to impact-rated units and may pull the existing electrical panel into compliance, widening the scope beyond what the square footage alone suggests.

Common Home Additions & ADU Problems We See in Gladeview Homes
- Older CBS homes that don’t meet current hurricane code. Most Gladeview housing stock predates the 1992 post-Andrew code overhaul and lacks modern hurricane straps and impact glazing. Any addition we tie into the existing structure will almost certainly trigger mandatory upgrades to bring the whole assembly into HVHZ compliance, which is a scope expansion you deserve to know about before you sign.
- Single-pane jalousie and aluminum windows. These are everywhere in the 33147 zip code, and the county won’t pass a final inspection on an addition if the existing window schedule doesn’t meet impact requirements. We factor this into your estimate up front, not as a surprise later.
- Flat or low-slope roofs from the 1950s and 60s. Original roofing on Gladeview’s older CBS homes often fails current HVHZ standards. When we add square footage, the roof-to-wall connection on the existing structure has to be evaluated, and in many cases, reinforced.
- Shallow Miami Limestone and a rising water table. Below-grade work like footings, slabs, and drainage rough-ins is time-sensitive here. Dewatering is common during the wet season, and scheduling around the water table can add days to the foundation phase. We plan for it instead of pretending it won’t happen.

Yes, on every eligible job. Gladeview is unincorporated, so all permits run through Miami-Dade County’s central permitting office, not a local city counter. We handle the county submission, schedule every inspection, and make sure the final sign-off happens before we call the job done. The permit inspector works for you, not for me, and that’s the way we like it.
We schedule work based on the order we receive signed proposals, and county permitting timelines in Gladeview add lead time that a local city hall wouldn’t.

Only if the scope changes, and only in writing. Every new scope item, every allowance adjustment, every price change gets issued to you as a written change order before any work happens on it. If it’s not on paper, it’s not on your bill. That’s a rule Tom Barrett has kept since 1998.
Yes. Every completed job is backed by our written 90-Day Done Right Promise. If something isn’t done right, one call brings Tom back to make it right.
