Fast, Reliable Home Additions & ADU Across Miami Shores
Adding square footage to a home in Miami Shores means navigating a very specific maze: the village runs its own Building & Zoning Department, separate from Miami-Dade County, and your plans have to satisfy both the village’s architectural review and the county’s High Velocity Hurricane Zone code before anyone swings a hammer. Most contractors from outside the village don’t know the first layer exists until a permit gets rejected or a review board sends the drawings back. We’ve worked through that process many times over, and we know what the reviewers in Miami Shores will flag before they flag it. If you’re weighing a room addition, a garage conversion, or a detached ADU here, call (877) 610-1318 and we’ll walk you through what’s actually involved, including a free estimate and a written scope before anything begins.
Why Barrett & Sons Construction Is Miami Shores’s Preferred Home Additions & ADU Company
Tom Barrett started this company in 1998, and his sons run the crews. When we take on a Home Additions & ADU job in Miami Shores, the person who shakes your hand at the first meeting is the same person who will be on-site most days. That matters here more than in most places, because a Miami Shores addition isn’t a generic build. It’s a conversation with the village’s design guidelines, which protect the 1930s-to-1950s Mediterranean Revival character of streets like Northeast 96th Street and the blocks around Barry University. We know what materials, rooflines, and window styles the review board expects, and we factor those into the plan from day one instead of discovering them mid-project.
Miami Shores homeowners tend to be thorough. They’ve usually lived in the village a long time, they know their neighbors, and they want to see the license number and the address before they sign. Tom publishes all of that, and a live person answers our phone around the clock. We’re not a franchise dispatching strangers from another county. We coordinate scheduling from our South FL office, and the crews serving Miami Shores are local men and women, background-checked, uniformed, and carrying the Barrett & Sons name on every truck. If something isn’t right after the job, the 90-Day Done Right Promise means one call brings Tom back. That guarantee is written on the contract, not implied in a handshake.
We’ve also walked into enough Miami Shores remodels to know what the previous contractor left behind: permits that were never pulled, windows that don’t carry a Miami-Dade Notice of Acceptance, additions that failed village review and got ordered back to original. That’s exactly the kind of surprise this neighborhood’s homeowners shouldn’t have to absorb twice. Our position is simple: every eligible job gets permits pulled and inspections signed, every scope change lands as a written change order before work proceeds, and no allowance stays verbal if it belongs on paper.
Our Home Additions & ADU Services in Miami Shores
A home addition in Miami Shores is rarely a simple bolt-on. The lot sizes, the setback rules, the village review process, and the HVHZ wind-load requirements all shape what’s buildable. Here’s what we handle most often in the 33153 zip code:
ADU Design & Permitting
An ADU in Miami Shores starts on paper, and every sheet of that paper matters. The village’s architectural review board will look at the exterior as closely as the structural engineer looks at the slab. We handle the full design and permitting path, including village submittals, HVHZ product vetting, and the county’s wind-load sign-offs, so the project doesn’t stall at the counter. A permitted ADU here typically runs $106,200 to $259,600 depending on size, finishes, and whether it’s attached or detached.

Garage Conversion ADU
Plenty of Miami Shores homes were built with detached garages that now sit half-empty. Converting one into a rental unit or an in-law suite is often the most cost-efficient path to an ADU here, because the structure already exists and the village generally views the conversion more favorably than new construction on a tight lot. Expect a garage conversion in Miami Shores to land between $35,400 and $94,400. We evaluate the existing slab, the roofline, and the original wiring before we quote, because those three factors swing the price more than anything else in these 1940s-era CBS garages.

New Detached ADU
When the yard allows it, a new detached ADU gives Miami Shores homeowners a fully separate rental unit or guest house. These projects require new foundation work, full HVHZ-rated exterior assemblies, and village review of the roofline and exterior finish. We’ve done enough of them along Northeast 2nd Avenue and the quieter streets east of Biscayne Boulevard to know exactly which wall assemblies and window packages the inspectors will accept the first time. Budget for $106,200 to $259,600 on a new detached ADU here, with the final number driven by square footage, site preparation, and interior finish level.

Junior ADU & Interior Conversion
A junior ADU typically means converting existing interior space, like a large bedroom, a den, or an enclosed porch, into a self-contained living area with its own entrance, kitchenette, and bath. In Miami Shores, these tend to be the most straightforward permit path, because the exterior envelope usually stays untouched, which keeps the village’s architectural review simple. Interior conversions here commonly fall between $53,100 and $153,400, depending on whether plumbing and electrical need to move and how much of the original terrazzo or plaster you want to preserve.

Trusted Brands We Service in Miami Shores
When we build in Miami Shores, we specify materials by name so you can look them up before they go in. For hardscape and driveway work tied to an addition, we regularly install Techo-Bloc and Cambridge Pavers products, both of which hold up well to the salt air and heavy seasonal rain coming off Biscayne Bay. We also use Quikrete concrete mixes on slabs and footings when the structural engineer calls for a specific compressive strength. These aren’t mystery brands off a van. They’re products with published specs, and we stock local parts and materials so Miami Shores jobs don’t wait on a freight shipment from out of state.
Common Home Additions & ADU Problems We See in Miami Shores Homes
- Village review misses. A contractor pulls a county permit but never files with Miami Shores Village’s Building & Zoning Department. The work starts, a neighbor calls, and the village issues a stop-work order. We handle both layers from the first week, so the project never runs into this wall.
- Non-NOA windows and doors. A previous addition used off-the-shelf impact products that don’t carry a Miami-Dade Notice of Acceptance. The HVHZ code requires the NOA stamp, and the village inspector will catch it. We spec NOA-rated products from the first drawing, because replacing a wrong window later costs double.
- Flat-roof and stucco failure on original CBS homes. Many Miami Shores homes from the late 1930s through early 1960s still carry their original built-up flat roofs and stucco. Salt air and humidity accelerate delamination, and the envelope starts leaking before anyone notices. An addition that ties into a failing envelope just spreads the problem. We inspect the existing structure before we add to it.
- Electrical panels at capacity. Older Miami Shores homes often have panels that were sized for a 1950s household. Adding a new ADU or a second story can exceed the panel’s capacity on paper, and the village won’t sign a final inspection on an overloaded system. We factor panel upgrades into the written scope so there are no electrical surprises later.
Pricing for Home Additions & ADU in Miami Shores, FL
A home addition in Miami Shores generally falls between $53,100 and $153,400, while a full ADU runs $106,200 to $259,600. What moves the number the most is the second story versus the ground-floor addition, the foundation work required, whether the village review demands specific exterior materials, and how much of the original home’s electrical and plumbing needs upgrading. A garage conversion in Miami Shores is usually on the lower end, around $35,400 to $94,400. A new detached ADU is on the upper end. Every job gets a written line-item quote before any work starts, and any change during the job arrives as a written change order, signed before the extra scope touches the project. Call (877) 610-1318 for a free estimate and a scope you can actually read.

FAQs - Home Additions & ADU in Miami Shores
A permit for an ADU in Miami Shores typically takes several months from first submittal to approval, because the plans have to clear both the village’s architectural review and Miami-Dade County’s HVHZ review. Projects that skip the village submittal get rejected and restart the clock. We handle both layers from the first drawing and submit complete packages the first time. Call (877) 610-1318 and we’ll give you a realistic timeline for your specific lot and scope.
A garage conversion ADU in Miami Shores typically runs $35,400 to $94,400. The spread depends on the condition of the original garage slab and roofline, whether the existing wiring will pass the village’s inspection, and the finish level you choose. We give you a written line-item quote so you can see exactly where each dollar goes. Call (877) 610-1318 for a free estimate.
Yes, we serve all of Miami Shores, including the neighborhoods around Barry University, the streets off Northeast 96th Street, and the homes east of Biscayne Boulevard. The whole village shares the same 33153 zip code and the same dual permit path, and we know each block’s typical lot size and setback constraints.
Only if you change the scope, and only after you approve a written change order. We don’t work off verbal allowances or surprise invoices at the end. If the village review requires a different exterior material, that lands on paper before the extra work starts. That’s the only honest way to price a build in a village with its own architectural review. Call (877) 610-1318 to talk through your project and see how we price it.
Generally yes, and the reason is structural: Miami Shores Village’s architectural review requires specific exterior finishes and rooflines that generic county-approved plans don’t have to meet, and those requirements add material cost. On top of that, every exterior product has to carry a Miami-Dade NOA stamp, which is a stricter vetting standard than most of the state uses. A home addition here typically runs $53,100 to $153,400, while parts of unincorporated Miami-Dade can come in lower. You’re paying for a village that protects its character, and the finished product reflects that. Call (877) 610-1318 and we’ll break down exactly where the local costs come from.
