AfterFast, Reliable Home Additions & ADU Across Lauderhill
Home additions and ADU construction in Lauderhill typically run $45,000-$130,000 for room additions and $90,000-$220,000 for detached ADUs, with most projects requiring 8-16 weeks from permit to final inspection. We coordinate dispatch and scheduling from our Miami office and serve Lauderhill with crews who know the difference between a 1972 CBS ranch near Inverrary and a 1980s garden condo off Commercial Boulevard. Call (754) 714-6540 to schedule your free estimate.
Lauderhill’s housing stock is dominated by pre-1980 CBS (concrete block and stucco) homes and 1970s-era garden-style condo complexes built before Hurricane Andrew’s code overhaul, yet the city sits squarely inside Florida’s High Velocity Hurricane Zone (HVHZ)-Broward and Miami-Dade Counties only-meaning every permitted renovation or re-roof must meet the nation’s most stringent wind-resistance standards. This combination of aging, non-compliant structures and HVHZ compliance requirements makes virtually every significant construction project in Lauderhill a code-upgrade job, not just a build-or-repair job. That’s why our quotes include a structural inspection before we write the price, and why we build allowances into the contract for what we’ll find once walls are open.
Why Rowan Construction Group Pompano Beach Is Lauderhill’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 Lauderhill specifically, our crews have cut openings into load-bearing block walls from the Inverrary Golf Club area to the neighborhoods off NW 56th Avenue, and we’ve learned what these 1970s CBS homes hide: cloth-wrapped wiring, truss seats without hurricane straps, bottom plates rotted from years of standing water against the slab.
Our Lauderhill customers leave reviews that mention the same things: the written quote arrived before anyone picked up a tool, the photo record showed exactly what was found and what was done, and the final invoice stayed within a few percent of the number they agreed to. That’s not luck. It’s Clause 1 of the Haven Standard: the price is written before anyone starts, and no change proceeds without a signed change order.
Calls are answered by a live person 24/7, and our background-checked, uniformed technicians arrive with a documented photo record as standard - not an upgrade. We don’t promise same-day construction; we promise a same-day response to schedule your free estimate, and a written quote within 48 hours of our inspection.
Local knowledge matters here. Lauderhill sits at near-sea-level elevation with a high water table, so summer convective storms routinely overwhelm flat-lot drainage. Our crews know to spec finish-grade elevation, stem-wall height, and subsurface drainage on every ground-up or addition project - not as an upsell, but as a requirement for work that lasts.
Our Home Additions & ADU Services in Lauderhill
ADU Design & Permitting
ADU construction in Lauderhill runs $90,000-$220,000, and the permitting process is where most projects live or die. Broward County’s HVHZ requirements mean your ADU plans must include wind-load calculations, impact-rated openings, and roof-to-wall connections that meet the strictest standards in the nation. We handle the full design-build permit package, including site plans that account for Lauderhill’s high water table and setback requirements on the city’s typically flat, quarter-acre lots. Our Home Additions & ADU team submits complete packages to avoid the revision cycles that delay most Lauderhill ADU starts by 3-6 months.
Garage Conversion ADU
A garage conversion ADU in Lauderhill typically costs $30,000-$80,000, but the real question is whether the existing structure can carry the load. Most Lauderhill garages share the same slab as the house, built without stem walls or proper vapor barriers. We inspect the slab edge, the existing roof structure, and the electrical service before we quote - because converting a garage without upgrading the 60-amp cloth wiring or adding hurricane straps to the truss seats is a permit rejection waiting to happen. On a recent conversion near Wiles Road, we found the garage slab had settled 2 inches from the house slab; we priced the stem-wall retrofit and subfloor vapor barrier in the original quote, not as a mid-project surprise.
New Detached ADU
New detached ADUs in Lauderhill face the full HVHZ code: impact windows, reinforced concrete block or frame construction with continuous load paths, and roof assemblies rated for 170-mph wind speeds. The $90,000-$220,000 range reflects foundation work that accounts for Lauderhill’s standing-water risk - stem walls set above finish grade, perimeter drainage, and vapor barriers that keep the bottom plate dry through our summer wet season. We source materials from fifty-plus vetted brands, including Owens Corning and Atlas roofing systems rated for HVHZ exposure, so the written quote reflects honest numbers rather than inflated allowances.
Junior ADU & Interior Conversion
Junior ADUs - a self-contained unit within the existing footprint - are increasingly popular in Lauderhill’s 1,200-1,500 square foot CBS ranches, where homeowners want rental income without the cost of ground-up construction. These projects still trigger HVHZ compliance on the existing structure once a permit is pulled, including updated electrical service, hardwired smoke detection, and often a full re-roof with hurricane straps. We price the interior conversion and the mandatory code upgrades as separate line items in the written quote, so you see exactly where the money goes.
Room Additions
Room additions in Lauderhill run $45,000-$130,000 and represent the majority of our local work. The typical project is a 300-500 square foot family room or master suite addition on a 1970s CBS ranch, which means cutting into a load-bearing block wall and tying a new roof into an existing flat or low-slope assembly. We find the same problems repeatedly: no hurricane straps, outdated wiring, and rot in the bottom plate from poor drainage. Our process is inspection first, allowances written into the contract, and any surprise priced and approved in writing before we touch it.
Second Story Additions
Second story additions on Lauderhill’s single-story CBS homes require a full structural analysis - most were built without the footings or wall reinforcement to carry a second floor. We bring in a structural engineer as part of our pre-quote inspection, and we include the engineering report and any foundation reinforcement in the written price. This is not a project where “we’ll see what we find” is acceptable; the structural package is either in the quote or it’s not a quote you can trust.
Sunrooms & Enclosed Patios
Sunrooms and enclosed patios are the entry point for many Lauderhill homeowners, but even these smaller projects require HVHZ-rated windows and doors, proper foundation isolation from the existing slab, and roof connections that transfer wind loads to the ground. We enclose patios with the same documentation discipline as our full additions: written scope, written price, photo record on every visit.

AfterTrusted Brands We Service in Lauderhill
We source across fifty-plus vetted brands so our written quotes carry honest numbers rather than inflated allowances. For Lauderhill’s HVHZ environment, we regularly specify Owens Corning Duration shingles with SureNail technology for roof tie-ins on additions, IKO Cambridge architectural shingles on garage conversion ADUs where the existing roof is being replaced, and Atlas StormMaster Slate on detached ADUs requiring Class 4 impact resistance. We stock common HVHZ-rated window and door sizes locally to avoid the 8-12 week lead times that delay most Lauderhill projects, and our relationships with these manufacturers let us lock pricing at quote time - no escalation clauses, no surprises.
Common Home Additions & ADU Problems We See in Lauderhill Homes
- Outdated wiring hidden in block walls. We regularly find 60-amp cloth-wrapped wiring in Lauderhill’s pre-1980 CBS homes, especially near Inverrary and the neighborhoods off NW 56th Avenue. A permitted addition triggers a full electrical inspection, and that old wiring won’t pass. We inspect before we quote and build the service upgrade into the written price.
- No hurricane straps at truss seats. Lauderhill’s 1970s homes were built before straps were required, but HVHZ compliance means every truss must be tied to the wall with a rated connector. This isn’t just the addition - it’s the existing structure, too. We price the full strap package, not just the new square footage.
- Standing water against foundations. Lauderhill’s high water table and flat lots mean summer storms push water against slabs that were never designed for it. Bottom plates rot, stucco delaminates, and rebar corrodes. We spec stem-wall height, finish-grade slope, and subsurface drainage on every addition to move water away from the structure.
- SB 4D milestone inspection triggers on condo additions. Lauderhill’s 1970s-era garden condo complexes are now subject to mandatory structural inspections under Florida’s post-Surfside legislation. If you’re adding to or converting a unit in one of these buildings, the association’s SB 4D remediation schedule may affect your project’s timing and access. We review association documents before we commit to a start date.

FAQs - Home Additions & ADU in Lauderhill
Lauderhill sits in Florida’s High Velocity Hurricane Zone (HVHZ), which applies only to Broward and Miami-Dade Counties, so any permitted addition must pull the entire existing structure into compliance with the nation’s strictest wind-resistance standards - hurricane straps, impact-rated openings, and roof-to-wall connectors that Orlando’s building code does not require. That structural retrofit package typically adds 15-25% to project cost compared to non-HVHZ markets. Call (754) 714-6540 for a written quote that shows exactly where that money goes.
We stop work, document the condition with photos, and price the repair as a written change order before touching anything - that’s Clause 1 of the Haven Standard. On a 1972 CBS ranch near Inverrary, our crew cut a 12-foot opening into a load-bearing block wall for a room addition and found 60-amp cloth-wrapped wiring, no hurricane straps at the truss seats, and black rot in the bottom plate from years of standing water against the slab. We priced the structural retrofit and HVHZ strap package in writing, then shot new stem-wall height and a subfloor vapor barrier as part of the rough-in so the addition’s floor drains away from the original slab. No work proceeds on a change until the change order is signed.
Yes. Broward County enforces HVHZ standards on the entire structure when a permit is pulled for a substantial addition, not just the new square footage. This means your existing roof may need straps, your windows may need impact rating, and your electrical service may need upgrading to pass inspection. We identify these requirements in our pre-quote inspection and build them into the original written price, not as mid-project surprises.
Florida SB 4D (2022) requires milestone structural inspections for buildings three stories or taller that are 30-plus years old, and Lauderhill’s dense inventory of 1970s-era condo complexes is generating a sustained backlog of structural remediation contracts. If you’re adding to or converting a unit in one of these buildings, the association’s SB 4D remediation schedule may limit access, require engineering review of your plans, or delay your permit until association-level repairs are complete. We review association documents and the building’s SB 4D status before we commit to a start date. Call (754) 714-6540 and we’ll check this as part of your free estimate.
We spec finish-grade elevation at least 6 inches above the surrounding slab, stem walls that isolate the addition’s foundation from the original structure, and perimeter subsurface drainage with a vapor barrier under the slab. Lauderhill’s near-sea-level elevation and summer convective storms make these non-negotiable - we’ve seen too many additions where the bottom plate rots within three seasons because the contractor set grade to match the existing slab. Call (754) 714-6540 for an exact quote; estimates are free.
