AfterFast, Reliable Home Additions & ADU Across Pinewood
A home addition or ADU in Pinewood typically runs $45,000 to $130,000, and the permit path here is different from most of Florida: every application goes through Miami-Dade County, not a city hall, and every inspection follows High Velocity Hurricane Zone code. That matters more than most homeowners realize, because Pinewood’s aging CBS homes almost always need structural upgrades the moment you add square footage. Barrett & Sons Construction has pulled permits in Miami-Dade for over 29 years, and Tom Barrett still walks every Pinewood job himself before we write a single change order. Call (877) 610-1318 and we’ll give you a straight answer on cost, timeline, and what the county will require.
Why Barrett & Sons Construction Is Pinewood’s Preferred Home Additions & ADU Company
We’re owner-operated, founded in 1998, and Tom’s sons run the crews that work in Pinewood. That’s not a marketing line. When you call, a live person answers. When you sign, Tom’s name, address, and license number are on the contract. Look them up before you commit to anything.
Pinewood homeowners have dealt with the other kind of contractor: the one who quotes low over the phone, shows up late, then hands you a bill that doesn’t match what you shook hands on. We do the opposite. Every scope item, every allowance, every price adjustment arrives as a written change order before work proceeds. An allowance that isn’t on paper is a surprise waiting for a date, and we don’t do surprises.
We also know what Miami-Dade’s Building Department will flag on Pinewood properties. The zip code here is 33167, and the housing stock is almost entirely concrete block and stucco from the 1950s through 1970s. Those homes sit on Miami Limestone with a high water table. That’s not background trivia; it changes how we spec footings, drainage, and tie-beam reinforcement on every addition we quote. We’ve done enough work around NW 103rd Street and the blocks near the Golden Glades to know what the inspector will ask before he asks it.
And when the job’s done, the written 90-Day Done Right Promise means one call brings Tom back. We live close enough that if something isn’t right, we want to know about it.
Our Home Additions & ADU Services in Pinewood
Our Home Additions & ADU team handles everything from a 400-square-foot garage conversion to a full second-story addition. Here’s how we approach the work most Pinewood homeowners call about.
ADU Design & Permitting
In Pinewood, an ADU permit runs through Miami-Dade County’s product-approval system. Every window, door, and roof component you specify has to carry a Miami-Dade NOA number, or the application bounces. We handle that paperwork from the first site visit through final inspection. Our design work starts with a survey of your existing slab and tie-beam condition, because most pre-1990 CBS homes in Pinewood need hurricane-mitigation upgrades to pass under HVHZ rules.
Garage Conversion ADU
Converting a garage in Pinewood typically costs $30,000 to $80,000, and the biggest variable isn’t finishes. It’s whether your existing slab can handle the converted load and whether the garage walls have the reinforcement Miami-Dade requires for living space. We’ve converted detached garages on lots throughout Pinewood, and we always walk the structure with a structural plan before we quote a number. Impact-rated openings are not optional here.
New Detached ADU
A new detached ADU in Pinewood generally runs $90,000 to $220,000. That range reflects what the ground does on your particular lot. The oolitic limestone sits close to the surface in much of this area, which means excavation for footings and underground utilities costs more than it would in a place with soft soil. Add the high water table, and your drainage design has to be right the first time. We’d rather quote that honestly than pretend the lot conditions don’t matter.
Junior ADU & Interior Conversion
A junior ADU, usually a bedroom-plus-sitting-room conversion inside an existing home, is the most budget-friendly way to add a rental or in-law unit in Pinewood. Because it uses existing conditioned space, you avoid the full foundation scope that a new build requires. But don’t think that means no county involvement. You’re still changing occupancy use on paper, and Miami-Dade will want plans, inspections, and likely upgraded egress. We pull the permits and stand by the inspection, every time.

Common Home Additions & ADU Problems We See in Pinewood Homes
Most Pinewood homes were built well before Hurricane Andrew changed the codebook, and that history shows up on nearly every addition we quote. These are the four we see most:
- Undersized tie-beams on original CBS construction. When we open a wall on a 1960s Pinewood home, the beam often doesn’t meet current HVHZ wind-load standards. Miami-Dade will require reinforcement before a final inspection passes. We account for that in the original scope, not as a surprise later.
- Original jalousie windows that fail impact requirements. Any room addition that touches existing openings means those openings have to meet current impact standards. Jalousie windows, still common throughout Pinewood’s older blocks, don’t qualify. We spec impact-rated replacements and carry the NOA paperwork through permitting.
- Flat or low-slope roofs that drain poorly during summer storms. Pinewood gets pounded, and low-slope roofs from the 50s and 60s weren’t designed for what’s expected now. When we tie a new addition into an existing roofline, we correct the drainage profile rather than propagate a problem.
- Miami Limestone making excavation slow and expensive. The rock under Pinewood does not dig like Florida sand. Every footing, every utility trench, every drainage line costs more here than it does in areas with soft soil. If a contractor quotes you Pinewood work without mentioning limestone, they haven’t done much work in 33167.
Pricing for Home Additions & ADU in Pinewood, FL
A full home addition in Pinewood typically runs $45,000 to $130,000. If you’re planning an ADU, you’re looking at a different band: $90,000 to $220,000 for a new detached unit, and $30,000 to $80,000 for a garage conversion. A junior ADU done inside existing square footage can fall meaningfully lower, but scope and structural findings move the number more than any single other factor.
What moves the price in Pinewood specifically: the condition of your existing tie-beams, whether your lot sits on shallow limestone, how many existing openings need impact-rated replacement, and whether drainage needs a full redesign. We put every one of those items in writing before work starts, and every change arrives as a written change order. No allowances that aren’t on paper. No count at the end that doesn’t match the count at the start.

FAQs - Home Additions & ADU in Pinewood
We schedule free estimates in Pinewood within a few business days, and because our crews serve the area regularly, we can often be on-site faster than that. Call (877) 610-1318 and we’ll give you a specific window when you call. There’s no trip charge inside the county, so the estimate costs you nothing.
Yes. Every eligible Pinewood project goes through Miami-Dade County’s Building Department with permits pulled and inspections signed. The High Velocity Hurricane Zone code applies to every addition we quote in 33167, and we carry the NOA paperwork so the permit doesn’t stall. The permit inspector works for you, not for me. That’s why we welcome him.
Not unless you change the scope, and if you do, it arrives as a written change order before any work proceeds. No surprise invoices at the end. The allowance that isn’t on paper is a surprise waiting for a date, and we don’t run jobs that way. Call (877) 610-1318 for a line-item quote you can compare.
In Pinewood, expect $45,000 to $130,000 for a home addition and $90,000 to $220,000 for a new detached ADU. The county’s HVHZ code and the limestone soil under the area tend to push structural and excavation costs higher than inland Florida, but you’re buying a structure that will actually pass inspection. We’d rather quote the real number once than revise it three times.
Every job we complete in Pinewood carries the written 90-Day Done Right Promise. If something isn’t done right, one call brings Tom back to make it right. That promise is on every contract, not buried in fine print. Ask anyone on your street, or look up the license number yourself.
