Fast, Reliable Home Additions & ADU Across Lauderhill
Home additions and ADU construction in Lauderhill typically run $45,000 to $130,000 for a room addition and $90,000 to $220,000 for a full detached ADU. The number moves because Lauderhill’s housing stock is unusually uniform: 1960s and 70s concrete-block homes from the Sadkin development era that predate Florida’s post-Hurricane Andrew building codes. When you open a wall or pour a new slab, the permit office will almost always require upgrades far beyond the original scope. We know that going in, we price it in writing, and we don’t hand you a surprise invoice at the end. Call (877) 610-1318 for a free estimate on your Lauderhill project.

Why Barrett & Sons Construction Is Lauderhill’s Preferred Home Additions & ADU Company
We’ve worked on enough 33310 ranches and split-levels to know what’s behind those CBS walls before the first hammer swings. Most Lauderhill homeowners call us after a national outfit quoted one number on the phone and showed up with another. It’s the same story every time: hidden conditions, unpermitted scope, a change order for work nobody approved. Tom Barrett founded this company in 1998, and his sons run the crews. When you call, a real person answers. When we price a Lauderhill addition, the allowances sit on the contract in writing. When the building department throws something new at the job, you see it in writing before we touch it.
Local reputation is the whole ballgame here. Lauderhill isn’t a big anonymous metro market. It’s a city where you see the same faces at the Inverrary Publix and the hardware store on University Drive. We answer to the neighbors who see our trucks on NW 44th Street and NW 56th Avenue. Our Lauderhill customers know our 90-Day Done Right Promise isn’t buried in fine print. If something isn’t right, one call brings Tom back. We also carry the permanent Senior & Veteran 10% discount and a free second opinion on any written estimate. That’s not marketing language. It’s how a 29-year-old family company keeps working in the same zip code.
Our Home Additions & ADU Services in Lauderhill
ADU Design & Permitting
This is where Lauderhill ADUs get complicated fast. The city’s Sadkin-era homes were built before South Florida’s modern wind-load standards, and Broward County’s impact glazing rules reach into nearly every renovation. We handle the permit package, the drawings, the product approvals, and the inspection scheduling. You’ll know what the building department requires before you’ve spent a serious dime. Our Home Additions & ADU team has pushed enough Lauderhill permits through to know what gets flagged and what passes clean.

Garage Conversion ADU
A garage conversion in Lauderhill typically runs $30,000 to $80,000. Most of these garages are attached, CBS-built, and built before modern energy codes. Expect a conversation about insulation, hurricane-rated glazing, and whether your existing electrical panel can handle a new living unit. If it can’t, we’ll write that subpanel and service upgrade into the scope before we start. The good news: attached garage conversions are often the fastest path to a rentable unit, because the structure already has a roof and three walls.

New Detached ADU
A new detached ADU in Lauderhill runs $90,000 to $220,000. The spread depends on square footage, foundation type, and how deep the groundwater sits on your specific lot. We’ve poured slabs in 33310 where water showed up at two and a half feet. That means dewatering, a proper vapor barrier, and sometimes engineered fill. Skip any of it and you get a mold problem inside two years. We don’t skip it. We price it on the front end, in writing.

Junior ADU & Interior Conversion
Converting an interior space, like a large den or an unused bedroom wing, into a junior ADU is often the most economical ADU path in Lauderhill. No new foundation, no new roofline, far fewer surprises. The catch is the same as every other permitted addition: once we open those CBS walls, the county’s code triggers arrive. Jalousie windows, a 100-amp panel, missing headers over load-bearing openings. We account for all of it in the estimate.

Trusted Brands We Service in Lauderhill
We run premium materials because our Lauderhill customers are done with mystery brands. For hardscape tie-ins, walkways, and driveway approaches on ADU projects, we use Techo-Bloc and Cambridge Pavers. For concrete work, slab pads, and footing pours, we spec Quikrete products we can stand behind. These are brands you can look up. We don’t load our Lauderhill jobs with whatever was cheapest at the supply house that week. If a material fails, you know exactly who made it, and so do we.
Common Home Additions & ADU Problems We See in Lauderhill Homes
- Jalousie windows that must go. Lauderhill’s original louvered glass windows are fully prohibited under current Broward County hurricane-impact glazing requirements. The moment your addition permit opens the walls, the building department asks what you’re doing about the rest of the windows. We price it from the first estimate so it doesn’t ambush you later.
- Shallow water table under the slab. Lauderhill sits on former Everglades sawgrass marsh. Groundwater often sits 2-3 feet below grade. Any new slab or footing needs dewatering, a vapor barrier, and proper drainage. We’ve seen homeowners skip it and pay for mold remediation within two years.
- Undersized electrical panels. Most 1960s and 70s CBS homes in Lauderhill still run a 100-amp panel. Add an ADU with a kitchen and mini-split, and you’ve exceeded it. We flag the upgrade during the estimate, not mid-project.
- Missing headers and undersized framing. On a 1960s CBS ranch in the 33310 zip code, we opened a wall to tie in a new bedroom addition and found the original window had no header over the load-bearing opening, just a couple of 2x4s nailed flat. That’s a structural failure waiting on the next storm. We fix it properly and document it.

How We Handle Lauderhill’s Code Triggers
Here’s what makes working in Lauderhill different from any other city in Broward County. The city was developed almost entirely in the 1960s and 70s as one of South Florida’s first planned communities, founded by developer Herbert Sadkin. That left an unusually uniform stock of aging CBS homes and garden-style apartments, all predating Florida’s post-Hurricane Andrew building codes. Construction work here is disproportionately about bringing pre-1992 structures into compliance with current wind-load and hurricane-impact standards. Open a wall for an addition, and the inspector asks about windows, roof decking, strapping, and panel capacity. That’s a retrofit challenge far more concentrated in Lauderhill than in Fort Lauderdale or Plantation, where housing stock spans six decades and inspectors see far more variety.
The jalousie window issue is the clearest example. Those louvered glass windows are everywhere in Lauderhill’s Sadkin-era homes, and Broward County prohibits them under current hurricane-impact glazing rules. So nearly any permitted addition automatically turns into a whole-house window replacement conversation at the building department, adding cost and scope that contractors here learn to price in from the first estimate. We write that window package into the initial scope, not as a surprise. That’s the difference between an estimate you can trust and one that moves the minute the inspector shows up.

FAQs - Home Additions & ADU in Lauderhill
Lauderhill’s Sadkin-era homes were built with jalousie windows, and Broward County’s hurricane-impact glazing requirements prohibit them entirely on any structure that undergoes a permitted addition or renovation. Once a permit opens the walls, the building department requires impact-rated windows across the entire structure before it signs off on the rough-in. That means your addition quote needs to include a window package, or it will balloon mid-project. We price it up front and write it as a line item. Call (877) 610-1318 and we’ll walk through what your specific house needs.
Lauderhill sits on former Everglades sawgrass marsh, and groundwater often sits just 2-3 feet below grade. Any new slab-on-grade addition or ADU foundation requires dewatering during the pour, a proper vapor barrier under the slab, and drainage designed for a high water table. Skip those and the subfloor wicks moisture, grows mold, and fails within two years. We include dewatering and vapor barrier work in every Lauderhill foundation estimate, not as an afterthought. For an exact number on your lot, call (877) 610-1318.
The most common surprises are missing headers over load-bearing openings, rotted roof sheathing where flat or low-slope roofs have leaked for years, and original 100-amp electrical panels that can’t support a new addition. We’ve opened a 1960s ranch wall to tie in a bedroom addition and found the original window had no header, just a couple of 2x4s nailed flat. We installed a laminated beam, sistered the rafters, and wrote the window package into a change order before touching glass. Call (877) 610-1318 and we’ll do the same on your house.
Yes, and most Lauderhill garages are attached CBS structures, which make conversion easier than new construction. The hurdles are impact glazing on the new living space’s windows, insulation and energy code compliance, and electrical panel capacity. If your panel is 100 amps, you’ll likely need an upgrade before the building department signs off. Garage conversions in Lauderhill typically run $30,000 to $80,000. Call (877) 610-1318 and we’ll give you a written scope with the permits included.
It creates a hard deadline. June through November, any open roof structure or unclosed framing is a liability. We sequence second-story additions so the roofing and structural permits close out before peak storm exposure, which means starting structural work in the fall or winter when possible. If your project runs into summer, we prioritize getting the roof dried in and the framing tied down before any interior work proceeds. Call (877) 610-1318 and we’ll give you a realistic timeline for your specific addition.
