AfterFast, Reliable Home Additions & ADU Across Tamarac
Home additions and ADU construction in Tamarac typically run $45,000-$130,000 for room additions and $90,000-$220,000 for detached ADUs, with most aging-in-place garage conversions falling between $30,000-$80,000. We’re Rowan Construction Group, and our crews work Tamarac regularly - from the Mainlands to the Woodlands, from single-story CBS homes off Commercial Boulevard to condo conversions near University Drive. Dispatch and scheduling run through our South Florida office, but the crew that quotes your job knows Broward County permitting and has pulled ADU permits here before. Call (754) 254-7676 and we’ll put a written price in your hands before anyone picks up a tool.
Why Rowan Construction Group Fort Lauderdale Is Tamarac’s Preferred Home Additions & ADU Company
We’ve delivered 4,000-plus projects since 2007, every one with a written price before work started and a documented photo record when the crew left. In Tamarac, that discipline matters more than most places - this city’s pre-1994 housing stock was built before Florida’s post-Hurricane Andrew code changes, so permitting almost always surfaces conditions that newer cities don’t face.
Our Tamarac customers find us the way most people find contractors now: they read the three-star reviews, not the five-star ones, and they want to know what happens when something goes wrong. The answer is Clause 1 of the Haven Standard - a written price before any work starts, always - and the 365-Day Done Right Promise printed on every page, backed by terms, not an asterisk. If it’s not done right, we make it right.
A live person answers our phones 24/7. Our technicians are background-checked and uniformed. And every visit includes a documented photo record as standard - not an upgrade - so you have evidence of what was found and what was done.
Our Home Additions & ADU Services in Tamarac
ADU Design & Permitting
ADU permitting in Tamarac starts with understanding what Broward County will require on a 1960s or 1970s CBS home. We handle the full design package, structural drawings, and permit submission - and we flag the conditions that routinely surprise homeowners here, like the roof-to-wall connection retrofit that county inspectors require when the existing trusses are toe-nailed, not strapped. A typical detached ADU in Tamarac runs $90,000-$220,000, and we deliver that as a written flat price with scope, not a “call for quote” estimate.
Garage Conversion ADU
This is where we do our most frequent aging-in-place work in Tamarac. Converting an attached garage into a Junior ADU - a self-contained living unit under 800 square feet - typically costs $30,000-$80,000, depending on whether the existing slab needs leveling, whether the roof structure needs reinforcement, and what the permitting inspection surfaces. In the Mainlands, we converted an attached garage into a Junior ADU for a retiree who wanted a single-level suite with a zero-threshold shower and blocking in the walls for future grab bars. During the rough-in, the inspector flagged the existing toe-nailed trusses, so permitting required hurricane straps and roof-to-wall connections before we closed the walls. We added the strap retrofit as a written change order, poured a curbless shower pan, and installed a Moen grab-bar-ready valve; the punch list cleared on the first follow-up inspection.
New Detached ADU
Building a new detached ADU in Tamarac means working with minimal vacant land and a water table that sits 2-3 feet below grade. Site prep and foundation work often cost more here than homeowners expect - excavation, drainage, and slab moisture barrier details that newer cities with deeper water tables don’t require. We price this honestly in the written quote, with line items for slab, utilities, and connection to the main home’s sewer and electrical. No work proceeds on a change until the change order is signed; that’s the discipline that has kept our projects within a few percent of the agreed number.
Junior ADU & Interior Conversion
For homeowners who don’t want to build outward, we convert existing interior space - a den, a Florida room, or part of an oversized single-story layout - into a Junior ADU with kitchenette, full bath, and separate entrance where code allows. This keeps the project inside the existing footprint, often avoiding the roof-to-wall retrofit that exterior additions trigger. We rough in blocking for grab bars, specify curbless or low-threshold showers, and widen doorways to 32 inches minimum. The price depends on how much plumbing relocation is needed; a full interior conversion with bath and kitchenette typically falls in the lower half of our $30,000-$80,000 garage-conversion range.
Room Additions
Single-story room additions in Tamarac - master suite expansions, family room extensions, or enclosed patio conversions - run $45,000-$130,000. The key variable is whether the existing roof structure can be tied into without triggering the full wind-mitigation upgrade that Broward County requires on pre-1994 homes. We assess this during the initial site visit and document it in the written quote, so the price you agree to is the price you pay, plus or minus only signed change orders.

AfterTrusted Brands We Service in Tamarac
Our material sourcing runs across fifty-plus vetted brands, which means the numbers in your written quote are honest, not padded. For roofing tie-ins on additions, we specify GAF, Owens Corning, or CertainTeed shingles to match existing slopes and meet current wind ratings. For aging-in-place bathrooms, we install Kohler and Moen grab-bar-ready valves, curbless shower pans, and slip-rated tile. We don’t stock everything in a local warehouse - we source to spec, with delivery timed to the permit release date, so material isn’t sitting on a Tamarac driveway through afternoon thunderstorms.
Common Home Additions & ADU Problems We See in Tamarac Homes
- Budgeting only for the ADU scope and missing the hurricane-strap retrofit. On a 1970s Tamarac CBS home, Broward County inspectors will require roof-to-wall connectors before they’ll sign off on the addition permit. We identify this during the initial quote, not during the rough-in inspection.
- Skipping aging-in-place rough-in to save money now. Blocking for grab bars and a curbless shower pan add cost upfront, but retrofitting them later means tearing out finished tile and wallboard. We rough in both as standard on any aging-in-place quote.
- Underestimating slab and drainage work. Tamarac’s water table sits as shallow as 2-3 feet below grade. Any excavation, subfloor adjustment, or new foundation for a detached ADU requires dewatering and moisture management that inland or higher-ground cities don’t face.
- Assuming a garage conversion avoids permitting. Even a Junior ADU without a kitchen requires permitting in Broward County, and the inspector will check the existing structure against current code. The toe-nailed truss condition is nearly universal in Tamarac’s pre-1994 stock.

FAQs - Home Additions & ADU in Tamarac
Yes, almost certainly. Broward County inspectors require roof-to-wall hurricane connectors on any permitted addition or conversion in Tamarac when the existing structure has toe-nailed trusses, which is standard on pre-1994 CBS homes. We identify this condition during our initial site visit and include the strap retrofit as a line item in the written quote, so it’s priced before permitting, not surfaced as a surprise mid-project. Call (754) 254-7676 for an exact quote - estimates are free.
Yes, if the occupant plans to age in place. A curbless shower pan eliminates the trip hazard and allows wheelchair or walker access later; blocking in the walls lets grab bars install without tearing out tile. The upfront cost is $3,500-$10,000 for a tub-to-shower conversion versus significantly more to retrofit a finished bathroom. We rough in both features as standard on any aging-in-place quote. Call (754) 254-7676 to see how this fits your project.
Tamarac’s water table sits 2-3 feet below grade, which means any excavation for a detached ADU foundation or slab modification for a garage conversion requires dewatering, moisture barrier, and often a raised or engineered slab detail that inland cities don’t need. This adds cost but is not optional - a slab poured without moisture management will fail. We price this honestly in the written quote with line-item documentation. Call (754) 254-7676 for specifics on your site.
Build out is usually more practical. Tamarac’s single-story CBS homes from the 1960s-80s often lack the foundation and wall structure to support a second story without extensive engineering, and the flat or low-pitch roof geometry doesn’t lend itself to a clean second-floor addition. A single-story room addition or garage conversion stays within the existing structural logic and avoids the wind-load complications that a second story introduces on a pre-Andrew home. We assess both options during the site visit and quote the one that makes structural and financial sense. Call (754) 254-7676 to schedule.
Yes. The same inspector pool and code enforcement applies to additions, conversions, and re-roofing permits in Broward County. If your home was built before 1994 with toe-nailed trusses, the addition permit will trigger the same roof-to-wall connector retrofit your neighbor faced. The difference is timing: we identify this condition in the quote phase, not at the rough-in inspection. The retrofit is documented as a written change order if it’s outside the original scope, with your signature required before any additional work proceeds. Call (754) 254-7676 - we’ll check your roof structure during the free estimate and tell you exactly what permitting will require.
