AfterFast, Reliable Home Additions & ADU Across Miami Shores
Adding square footage to a Miami Shores home is rarely a simple bolt-on job. Most of the houses here are concrete block structures built between the late 1930s and early 1960s, which means the addition has to tie into a CBS wall system, carry a Miami-Dade NOA-rated roof assembly, and survive Village Hall’s architectural review before a single block gets laid. A full Home Additions & ADU project in Miami Shores typically falls between $53,100 and $153,400, with dedicated ADU construction starting around $106,200. If you’re weighing options or already have plans, call Barrett & Sons Construction at (877) 610-1318 and we’ll walk you through what’s realistic on your street.
We’ve pulled permits at Village Hall enough times to know exactly how Miami Shores works, and it doesn’t work like the rest of the county. The village runs its own Building & Zoning Department, entirely separate from Miami-Dade. Contractors unfamiliar with that structure routinely file the wrong paperwork, miss the architectural review step, and stall projects for months. We don’t. That local knowledge is the difference between a permit issued in weeks and a permit stuck in limbo.
Why Barrett & Sons Construction Is Miami Shores’s Preferred Home Additions & ADU Company
Tom Barrett founded this company in 1998, and his sons run the crews. That’s not marketing language, it’s the way the business works. When you sign a contract with us for an addition or ADU in Miami Shores, the person who shakes your hand is connected to the people swinging hammers. Tom lives in South Florida, his name is on the truck, and his phone number is published right alongside his license number. You can look both up before you sign anything.
Miami Shores homeowners tend to ask the same question after their first bad experience with an out-of-town contractor: “Will you actually show up?” We coordinate our Miami Shores work from our South Florida office, and our crews serve this village regularly. A live person answers our phone around the clock, not a voicemail box. When changes come up mid-project, and they will on a 1939 CBS home, you get a written change order before any new work starts. The allowance that isn’t on paper is a surprise waiting for a date, and we don’t do surprises.
Every eligible project here includes permits pulled and inspections signed. The permit inspector works for you, not for us, and that’s exactly why we want him on the job. Our 90-Day Done Right Promise is written on every contract: if something isn’t right, one call brings Tom back. We also carry a permanent 10% Senior & Veteran discount, and we offer a Free Second Opinion on any written estimate you bring us. The core of Miami Shores work, the village’s own rules, and honest pricing have earned us a reputation that stretches from North Miami to Pinewood.
Our Home Additions & ADU Services in Miami Shores
ADU Design & Permitting
Before the first block gets set, a Miami Shores ADU has to pass through Village Hall’s Building & Zoning Department. That means architectural review against the village’s Mediterranean Revival design guidelines and simultaneous compliance with Miami-Dade HVHZ wind load code. We prepare the drawings, file the Village permit, and stay on the inspection schedule until the sign-off happens. It’s slow, methodical work, and it’s the only way to avoid a stop-work order later.
Garage Conversion ADU
Many Miami Shores garages on 1930s and 1940s homes were never built to living-space standards. Converting one means addressing the slab, the flat or low-pitched roof membrane, and jalousie window replacement while keeping the street-facing elevation acceptable to the village’s architectural review. A garage conversion ADU in Miami Shores runs $35,400 to $94,400. We also handle Kitchen Remodeling in Miami Shores when the conversion includes a kitchenette, which most do.
New Detached ADU
Building a detached ADU in Miami Shores is a ground-up CBS build under the strictest wind-load regulations in the country. Every window, door, and roofing product must carry a Miami-Dade NOA. We plan foundation ties, impact-rated openings, and drainage away from the existing structure, then submit the full package to Village Hall before we mobilize. Expect this to be the most expensive option, starting around $106,200, because the village’s standards leave no room for shortcuts.
Junior ADU & Interior Conversion
A junior ADU, usually a converted spare bedroom or den with its own entrance and a small wet bar or efficiency kitchen, is often the fastest path to rental income in Miami Shores. Interior conversions typically avoid the heaviest architectural review because the change isn’t visible from the street, but the plumbing, electrical panel, and egress still have to meet current code. We handle the full scope, including bath additions, and Bathroom Remodeling in Miami Shores when the JADU needs one.

Trusted Brands We Service in Miami Shores
We install materials you can look up, not mystery products off a van. For hardscape tie-ins around new additions and ADUs, we carry Techo-Bloc and Cambridge Pavers because both hold up to Miami Shores’s humidity and salt air without fading the way bargain pavers do. For concrete work, we use Quikrete products rated for South Florida conditions. We stock common components for Miami Shores jobs at our local yard, so a mid-project change doesn’t idle your crew for two weeks.
Common Home Additions & ADU Problems We See in Miami Shores Homes
- Stucco delamination at the addition tie-in. Miami Shores humidity and salt air from Biscayne Bay get behind stucco where the new wall meets the old CBS one. We see this on nearly every two-year-old addition built by crews unfamiliar with local moisture patterns.
- Village architectural review rejections. Contractors who skip the village’s design guidelines get sent back to refile, and sometimes ordered to restore original finishes at the owner’s expense. We submit compliant plans the first time.
- Flat roof membrane failures on converted garages. The seasonal heavy rainfall here is brutal on low-pitched built-up roofs, especially on 1950s garages converted to living space without a full roof replacement.
- Electrical panels at capacity. An addition or ADU on a 1948 block home frequently needs a panel upgrade to carry the new load, and the village inspector will flag it if it’s undersized. We plan for that before the walls go up.
Pricing for Home Additions & ADU in Miami Shores, FL
The lead range for a home addition in Miami Shores is $53,100 to $153,400. On the lower end, you’re looking at a modest room addition or a sunroom with minimal foundation work. On the higher end, a second-story addition or a full detached ADU with kitchen and bath pushes that number up quickly. Dedicated ADU construction in Miami Shores lands between $106,200 and $259,600 depending on size, site prep, and finish level. Garage conversions run $35,400 to $94,400. What moves the number: structural tie-ins to existing CBS walls, roof system replacement, whether the village requires architectural review changes, and whether the electrical panel needs an upgrade. We give written, line-item estimates before any commitment, and every change after that arrives as a written change order. Call (877) 610-1318 and we’ll price your specific scope.

The permit inspector works for you, and we don’t skip the step that other contractors do.
A garage conversion ADU in Miami Shores typically runs $35,400 to $94,400, while the same project in North Miami under county jurisdiction often lands slightly lower because the village’s architectural review and stricter HVHZ adherence add design and inspection time.

Every eligible job includes permits pulled and inspections signed. Miami Shores operates its own Building & Zoning Department through Village Hall, entirely separate from Miami-Dade County, and we file through the correct channel every time.
