AfterFast, Reliable Home Additions & ADU Across North Lauderdale
A home addition in North Lauderdale typically runs $45,000 to $130,000, while a detached ADU usually lands between $90,000 and $220,000 depending on size, foundation work, and finish level. Garage conversions are the most budget-friendly path at $30,000 to $80,000. Most jobs take 4 to 10 months from permit to final inspection, and we coordinate every step so you’re never left guessing what comes next.
North Lauderdale isn’t a city where you can treat construction as a one-size-fits-all project. The housing stock here is almost entirely CBS block homes from the 1970s and 1980s, built before Hurricane Andrew rewrote Florida’s building code. That means when we open a wall for an addition, we find things a newer neighborhood wouldn’t. We’re prepared for that, and we price it honestly before the first hammer swings. Call (877) 610-1318 to schedule a free estimate and walkthrough.
Key Takeaways:
- Home additions in North Lauderdale: $45,000-$130,000; ADUs: $90,000-$220,000; garage conversions: $30,000-$80,000
- Older CBS homes often require wind-mitigation and electrical upgrades when walls open for an addition
- North Lauderdale’s high water table demands dewatering and slab-on-grade foundation design for any detached structure
- Every allowance and price change comes as a written change order before work proceeds
- Permits pulled and inspections signed on every eligible Home Additions & ADU project
Why Barrett & Sons Construction Is North Lauderdale’s Preferred Home Additions & ADU Company
Tom Barrett started this company in 1998, and his sons run crews today. That means the person you shake hands with at the estimate is the person accountable when the inspection happens. We’re not a franchise dispatching strangers to your door. We serve North Lauderdale from our metro South Florida office, and our crews know the streets off Rock Island Road, the neighborhoods around SW 81st Avenue, and the permitting quirks at Broward County that can stall a project if you don’t know them.
North Lauderdale inspectors are thorough, and for good reason. This city has a backlog of unpermitted work from the 1980s build-out era, so the building department scrutinizes structural plans carefully. We’ve navigated that process enough times to know what gets flagged ahead of time. We write allowances into the contract for the code upgrades that typically surface once walls open, which keeps your budget realistic from day one. Tom Barrett’s name, address, and license number are published openly. Look them up before you sign anything. That’s how we’ve operated for 29 years, and it’s why homeowners here recommend us to neighbors.

Our Home Additions & ADU Services in North Lauderdale
ADU Design & Permitting
Building an ADU in North Lauderdale means starting with the water table. This city sits on former Everglades drainage land, and groundwater is often just inches below grade. A proper design accounts for that before we ever file for a permit. We handle architectural drawings, structural engineering, and the Broward County Notice of Commencement filing that virtually every structural project here requires. You get one point of contact from first sketch to final inspection.
Garage Conversion ADU
Most garages in North Lauderdale CBS homes were built as open-air car shelters that someone enclosed along the way. Some have permits, many don’t. We start with a records pull to determine what the county has on file, then design the conversion to meet current code. Expect insulation retrofits, electrical panel upgrades, and likely impact-rated openings for windows and doors. A garage conversion here runs $30,000 to $80,000 depending on what the slab and roofline require.
New Detached ADU
A standalone ADU in zip code 33068 gives you the most design freedom, but it also demands the most from the site. North Lauderdale’s flat topography and shallow groundwater mean we dewater during excavation and pour a reinforced slab-on-grade designed for hydrostatic pressure. We coordinate the foundation, tie-downs, and roof-to-wall connections so the finished structure meets current wind-mitigation standards, not the looser rules that governed 1970s construction.
Junior ADU & Interior Conversion
Converting an existing interior space into a junior ADU is often the fastest and most cost-effective option in North Lauderdale. We’ve built them from spare bedrooms, enclosed lanais, and even former utility rooms. The catch here is that many interior conversions were originally done without permits during the 1980s, and inspectors will flag the work if it’s visible during your inspection. We check the county records first so you know what you’re working with before you spend money on finishes.

Trusted Brands We Service in North Lauderdale
We install and service premium window and door brands across our Home Additions & ADU projects, including PGT, Simonton, and CGI.

We work with local North Lauderdale suppliers to keep material lead times short, and we stage deliveries around the hurricane season schedule so materials don’t sit exposed in a storm window.
Common Home Additions & ADU Problems We See in North Lauderdale Homes
- Unpermitted 1980s additions hiding behind stucco. North Lauderdale inspectors are quick to flag screen rooms or room additions that were never permitted. If your new ADU ties into that space, retroactive permits or demolition must be resolved first. We pull records before we plan around existing work.
- Water in the footer trenches. The high water table here means standing groundwater appears in excavation trenches within hours. Without dewatering and proper slab design, you get settlement and moisture intrusion in the new structure. We plan for this from day one.
- Wind-mitigation upgrades triggered by opening a wall. Older CBS homes lack modern truss-to-wall strapping and often have aluminum wiring. Once the permit is pulled and the wall is open, current code requires correction. We write allowances for these upgrades into the contract so the cost doesn’t blindside you mid-project.
- Roof tie-in failures on additions. The original 3-tab shingle or 2-ply modified bitumen roofs on these homes weren’t built to connect cleanly to a new addition roofline. We inspect the existing roof structure before designing the tie-in, so your new space doesn’t leak at the seam where old meets new.
Pricing for Home Additions & ADU in North Lauderdale, FL
You should know what a project costs before you commit, not after the walls are open. Here are the honest ranges for North Lauderdale’s market, based on the homes we work on here every week:
| Project Type | Typical Range in North Lauderdale |
|---|---|
| Home Addition | $45,000-$130,000 |
| ADU Construction | $90,000-$220,000 |
| Garage Conversion | $30,000-$80,000 |
What moves the number is what we find when we open the walls. Aluminum wiring that needs replacement, missing hurricane strapping, or a slab that wasn’t poured to today’s standard all require code-mandated corrections. We handle this differently than most: we inspect first, write allowances into the contract for known risks, and put every price change in writing before work proceeds. The allowance that isn’t on paper is a surprise waiting for a date. Call (877) 610-1318 for a free estimate that reflects real conditions in your home, not a national average.

FAQs - Home Additions & ADU in North Lauderdale
Once a permit is pulled and a structural wall is opened, current Florida Building Code applies to everything we touch. On a 1970s CBS home, that typically means adding hurricane strapping from trusses to walls, replacing aluminum wiring if it’s present, and installing impact-rated openings for any new windows or doors. We write allowances for these known items into the contract up front so the cost is visible from the start. Call (877) 610-1318 and we’ll walk your specific home before you commit to anything.
It changes the entire foundation approach. Groundwater sits just inches below grade in much of North Lauderdale, so we dewater the excavation before pouring and design a reinforced slab-on-grade with proper drainage and moisture barriers. Skipping this step leads to settlement cracks and moisture wicking up through the slab. It costs more than a standard pour, and it’s non-negotiable on this land.
Usually yes, but the unpermitted space has to be addressed first. North Lauderdale inspectors will flag it when they inspect the new work, and you’ll face retroactive permits or demolition before the new addition gets signed off. We pull county records during our initial assessment so you know exactly what you’re dealing with before you spend a dollar on design. Call
It can. A properly permitted ADU with current wind-mitigation features like impact-rated windows, hurricane strapping, and a modern roof-to-wall connection can actually strengthen your insurance position on the new structure. However, if the ADU is attached to an older home without those features, your insurer may review the entire property. We build all new construction to current code, which is what insurers want to see.
We use a milestone-based draw schedule: an initial deposit, a draw at permit approval, a draw at rough inspection, and a final draw at certificate of occupancy. Each draw is spelled out in your contract before work begins, and any change to scope or allowance comes as a written change order with the updated price before that work proceeds. You never get a surprise invoice at the end. Call (877) 610-1318 for a written quote that includes the full draw schedule.

"Came back a year later to sort a door that had dropped as the frame settled. No charge and no argument about whether it was covered."
"Addition over the garage matched the original roofline and brickwork so closely that visitors do not realise it was added. He tracked down the closest brick he could find rather than settling."
