Why Rowan Construction Group Boca Raton Is North Lauderdale’s Preferred Home Additions & ADU Company

We’ve delivered 4,000-plus projects since 2007, and a growing share of them sit right here in North Lauderdale’s tight 4-square-mile grid. Homeowners here find us the same way they research appliances - they read the three-star reviews, then call to see if we’ll put a number in writing. We do. Every time.

Our response time to North Lauderdale is same-day or next-day for estimates, because our crews are already running permits through the Broward County Central Campus on Lauder Road. That matters when you’re trying to beat the seasonal permitting backlog that hits every June.

What builds trust here is specificity. We know the original aluminum wiring runs in these CBS walls. We know the iron pipe under the slab. We know the roof-to-wall connectors that inspectors will flag. And we write allowances for all of it into the contract before anyone picks up a hammer - Clause 1 of The Haven Standard, the discipline Haven acquired Rowan for in 2007.

Our Home Additions & ADU team includes background-checked, uniformed technicians who arrive with a documented photo record as standard - not an upgrade. A live person answers calls 24/7. The 365-Day Done Right Promise is printed on every page, backed by a terms page, not an asterisk.

Our Home Additions & ADU Services in North Lauderdale

ADU Design & Permitting

North Lauderdale’s fully built-out status means almost every ADU here is a garage conversion or a backyard detached unit on a lot that wasn’t planned for it. We handle the full design-build permit package through Broward County, including the HVHZ structural calculations that surprise homeowners who expected inland-county rules. A typical detached ADU in North Lauderdale runs $90,000-$220,000. We price the foundation work knowing the water table sits 2-3 feet below grade - slab failure from hydrostatic pressure is not a surprise we leave to chance.

Garage Conversion ADU

Garage conversions are the most common ADU we build in North Lauderdale, typically $30,000-$80,000. The 1970s-era garages in neighborhoods off Rock Island Road and McNab Road share the same problems: original slab with no moisture barrier, aluminum feeder lines that won’t carry modern load, and a roof structure that needs tie-down upgrades to meet current HVHZ standards. We inspect all three before we write the price. Under The Haven Standard, no work proceeds on a change until the change order is signed - the administrative discipline that has kept our projects within a few percent of the agreed cost across 4,000-plus jobs.

New Detached ADU

For homeowners with enough backyard, a new detached ADU offers the cleanest structural path - no tying into original CBS walls with their hidden wiring and plumbing. But even here, North Lauderdale’s conditions matter. The foundation must account for seasonal saturation. The electrical service often requires a panel upgrade from the original 100-amp aluminum-bus units common in 1970s construction. We source from fifty-plus vetted brands - including prefab partners like Abodu and Cover when the lot geometry and setback rules allow - to keep the written quote honest rather than inflated.

Junior ADU & Interior Conversion

A junior ADU, or interior conversion, reconfigures existing square footage - splitting a large 1970s ranch into a main unit and a self-contained apartment. In North Lauderdale’s single-story stock, this often means the original hallway bathroom becomes a kitchenette, and the back bedrooms gain a separate entrance. The challenge is the same every time: the walls open, and we find aluminum branch circuits, iron supply lines, and no wind-mitigation hardware. We build allowances for all three into the original contract, priced and documented, so the homeowner approves before we close another wall.

Room Additions

Room additions in North Lauderdale - typically $45,000-$130,000 - are where our field discipline shows most clearly. On a recent addition off a 1970s CBS ranch in the Rock Island Road area, we opened the rear wall and found the original aluminum branch wiring feeding the back bedrooms, rusted-out iron supply lines under the slab, and no roof-to-wall straps at the tie-in - none of it visible at the walkthrough. We halted, put the electrical rough-in, re-pipe, and connector retrofit in a written change order with a fixed price, and the homeowner approved it before we closed another wall. Final inspection sign-off passed on the first walk because every surprise was priced and documented up front.

ADU Site Prep & Utilities

Site prep in North Lauderdale is not generic excavation. The high water table means trenching for sewer lateral, water main, or electrical conduit requires dewatering plans and often crushed-stone bedding to keep utilities from floating in saturated soil. We coordinate with Broward County Utilities and Florida Power & Light on every detached ADU, pulling the permits and scheduling the inspections so the homeowner doesn’t chase agencies. The photo record we deliver at project close includes every utility trench, every connection, every pressure test - documentation that protects resale value and insurance claims.

Trusted Brands We Service in North Lauderdale

We source across fifty-plus vetted brands so the written quote carries honest numbers rather than inflated ones. For ADU and addition projects in North Lauderdale, that means KraftMaid and Wellborn cabinets for kitchenettes, Kohler and Toto fixtures for bathrooms, and GAF or Owens Corning roofing where the new structure ties into the original. We also evaluate prefab ADU systems from Abodu, Cover, and Dvele when the lot conditions and setback geometry allow - these can compress schedule and cost for qualifying properties. Everything is in the quote before work starts. No “call for pricing.” No allowances left open.

Common Home Additions & ADU Problems We See in North Lauderdale Homes

• Missing roof-to-wall connectors in original CBS construction. The 1965-1985 building wave in North Lauderdale predates modern wind-strapping requirements. Framing a new addition into these walls without addressing the connector gap means failing HVHZ inspection after the walls are closed. We inspect and price the retrofit before we tie in.
• Aluminum wiring and iron-pipe plumbing behind finished walls. Any addition that opens original drywall in a North Lauderdale home of this vintage will likely find both. We build electrical and plumbing allowances into every contract, with unit pricing, so the homeowner knows the ceiling before we start.
• Hydrostatic pressure at slab tie-ins and footings. Central Broward’s 2-3 foot water table saturates soils year-round. Digging without a dewatering plan causes failed waterproofing at the new-to-old wall junction. We account for this in foundation specs and pricing from day one.
• Outdated electrical panels unable to carry addition load. The original 100-amp aluminum-bus panels common in 1970s North Lauderdale construction won’t support a modern kitchen, HVAC, and laundry. We identify panel capacity at the walkthrough and include upgrade pricing in the written scope if needed.
