Fast, Reliable Home Additions & ADU Across Pinewood
A home addition or ADU in Pinewood typically runs $45,000 to $130,000 for a room addition and $90,000 to $220,000 for a new detached ADU. The range stays wide because of one thing most homeowners don’t see coming: Pinewood’s older CBS homes almost always trigger mandatory Miami-Dade HVHZ upgrades once a wall comes open. That’s not a hidden fee. It’s the code, and we write it into your allowance before we ever swing a hammer. Call (877) 610-1318 for a free estimate and we’ll walk you through exactly what your specific home will need.
Tom Barrett and his sons have worked on Pinewood’s post-war CBS stock for years, and we know what lives behind those stucco walls off NW 103rd Street and around NW 7th Avenue. We don’t quote flat numbers and hope. We inspect first, put every allowance in writing, and show you the permit application before the first inspection is scheduled. That’s how Home Additions & ADU work should run in an unincorporated area like this one.
Why Barrett & Sons Construction Is Pinewood’s Preferred Home Additions & ADU Company
Pinewood sits entirely within Miami-Dade County jurisdiction. That means no city hall permit desk, no municipal inspector. Every permit, every inspection, every product approval runs through the county’s Building Department and its High Velocity Hurricane Zone code. Plenty of contractors quote Pinewood jobs without ever having pulled a permit here, and the first time they do, the product-approval paperwork buries them. We file Miami-Dade NOA numbers on every window, door, and roof component as a matter of routine. It’s not extra work for us; it’s the only way we’ve done it since 1998.
Our Pinewood customers call us back because the person who signs the contract is the same person who shows up on site. Tom’s sons run the crews. Every scope change, every allowance adjustment, every surprise behind a wall arrives as a written change order before work continues. You’ll see the number in writing, approve it, and only then does a single nail move. If something isn’t done right, the 90-Day Done Right Promise is written on your contract: one call brings Tom back. We don’t hide behind a voicemail box either. A live person answers (877) 610-1318 24 hours a day.
We carry premium brand framing, sheathing, and finish products that meet Miami-Dade’s HVHZ product approval standards, and we don’t substitute mystery materials off a van. When we quote impact windows for a Pinewood addition, they carry NOA numbers you can look up yourself. Same with roof underlayment and fastening patterns. The permit inspector works for you, not for me, which is exactly why we like him.
Our Home Additions & ADU Services in Pinewood
ADU Design & Permitting
An ADU in Pinewood starts with the county’s product-approval system before it starts with a hammer. Every exterior door, window, and roof component on that structure needs a Miami-Dade NOA number listed on the permit application. We handle the design work, the structural engineering, and the county submittal as one package, so you don’t end up with plans that look fine and a permit that stalls. Most ADU permits in this zip code, 33167, take longer than homeowners expect because of HVHZ review. We price that time honestly and set expectations from the first meeting.

Garage Conversion ADU
Converting an attached garage in Pinewood usually lands between $30,000 and $80,000. The cost swings on what we find in the existing slab and tie-beam system. Many of these garages were built with no vertical rebar into the footing, and the moment we cut a new opening, the inspector will require a retrofit before rough-in passes. That’s a written change order, not a surprise invoice. We also have to check for termite damage in the bottom plates and moisture intrusion from the high water table that runs across much of the 33167 area.

New Detached ADU
A new detached ADU in Pinewood runs $90,000 to $220,000, and excavation is one of the first places the budget gets real. The oolitic limestone under this area sits just inches to a few feet below grade, so trenching for footings and utilities moves slower than in inland Florida markets. We budget for that on the front end and write the allowance plainly in your contract. The structure itself goes up to current HVHZ wind-load standards, which is actually a selling point: your new ADU will be rated for winds a 1960s house was never designed to face.

Junior ADU & Interior Conversion
A junior ADU carved out of an existing Pinewood home is the most budget-friendly path, typically running on the lower end of the addition range. We look for interior space that can be separated without touching the main roof structure, because once the roof deck comes off, you’re into full HVHZ reroof territory. These conversions still require their own egress, separate entry, and often a small kitchenette that meets county code. We pull the permits on every eligible job, and the final inspection gets signed before we call it done.

Trusted Brands We Service in Pinewood
For hardscape and footing work around a Pinewood ADU or addition, we install Techo-Bloc and Cambridge Pavers because both carry the documentation we need for county submittals and both hold up to South Florida’s wet-dry cycles. For concrete work, we use Quikrete products that meet the compressive strength specs Miami-Dade expects on ADU slabs and tie-beam repairs. We keep local inventory available for Pinewood jobs, so you’re not waiting on a truck from three counties away when the pour needs to happen this week.
Common Home Additions & ADU Problems We See in Pinewood Homes
- Pre-Andrew CBS walls with no vertical rebar. On a 1950s CBS ranch off NW 103rd Street, our crew opened a load-bearing wall for a kitchen addition and found the original tie-beam system had no vertical rebar into the footing, common for Pinewood’s pre-Andrew stock. We stopped work, priced the structural retrofit and Miami-Dade NOA impact windows as a written change order, and got inspection sign-off before closing the wall.
- Flat or low-slope roofs that trigger HVHZ reroof requirements. Once you add square footage and the existing roof ties into the new structure, the inspector usually requires the old roof brought up to current wind-load standards. That’s a real line item, not a scare tactic.
- Jalousie windows and non-impact openings. Any new addition with a jalousie window still in place will fail final inspection in Pinewood. Replacement impact-rated units with Miami-Dade NOA approval are mandatory, and we price them into the allowance from day one.
- Limestone excavation surprises. Footing trenches in 33167 hit oolitic limestone faster than most homeowners expect. We budget additional excavation hours and equipment in the contract so a rock shelf doesn’t turn into an unapproved upcharge.

FAQs - Home Additions & ADU in Pinewood
Yes, a structural engineer’s report is required for a second-story addition on a 1960s CBS home in Pinewood. The county reviews the existing tie-beam continuity, slab capacity, and wind-load path before they’ll approve the permit. We coordinate the engineer, the drawings, and the permit submittal together, and we write the engineer’s fee into your contract as a line item, not a surprise. Call (877) 610-1318 and we’ll tell you what your specific home will need.
No, you cannot convert an attached garage into an ADU in Pinewood without addressing the existing roof. Once the garage becomes conditioned living space, the county requires the roof structure and covering to meet current High Velocity Hurricane Zone standards, which usually means a full reroof with NOA-approved underlayment and fastening. We price that into the garage conversion range of $30,000 to $80,000 so there’s no surprise halfway through. Call (877) 610-1318 for a written quote that includes it from the start.
We stop work, document the rot, and bring you a written change order with the exact replacement cost before we remove another board. In Pinewood’s 33167 area, with the water table as high as it is, rotted subfloor plates and bottom chords are common in pre-1970s builds. You approve the number in writing, then we proceed. Nothing gets billed that wasn’t on paper first. That’s how Tom Barrett has run every job since 1998.
Yes, every new opening on a Pinewood room addition, sunroom included, must be impact-rated with a Miami-Dade NOA number. There is no exception for unenclosed or semi-enclosed spaces under current HVHZ code. We quote Andersen and Marvin impact units with the NOA documentation already in hand, and we show you the product approval paperwork as part of the permit application.
We budget for limestone in the original contract. In this part of Miami-Dade, oolitic limestone sits inches to a few feet below grade, so footing and utility trenches require rock equipment more often than not. We include an excavation allowance as a written line item, and if we hit rock early, you’ll see the additional equipment cost as a written change order before we keep digging. Call (877) 610-1318 for a free estimate that accounts for what’s actually under your Pinewood lot.
