Why Rowan Construction Group Pompano Beach Is Lighthouse Point’s Preferred Home Additions & ADU Company
We’ve delivered over 4,000 projects since 2007, and a significant share of them sit on Broward’s canal grid - including garage conversion ADUs off Sample Road and second-story additions on the Venetian Isles waterways. Lighthouse Point homeowners review us specifically for the documented photo record we leave behind and the fact that our final invoices land within a few percent of the written quote they signed. Our Miami-area office coordinates dispatch to Lighthouse Point daily, so we’re not driving down from Boca or across from Naples when you need a site visit.
What separates our work here from inland Broward jobs is the local knowledge we’ve built through repeated permit pulls with Broward County’s Lighthouse Point jurisdiction - the seawall inspections, the HVHZ wind-load calculations, the marine-grade fastener specs that salt-air corrosion demands on canal-front lots. We know which 1960s-era poured-concrete seawalls are likely to get flagged before the county inspector does, and we write allowances into the contract so you’re not financing a seawall replacement from a surprise invoice.
Our Home Additions & ADU Services in Lighthouse Point
ADU Design & Permitting
Every ADU in Lighthouse Point starts with a permit strategy, not a floor plan. Because nearly every lot here sits on or within steps of a navigable canal, your ADU permit triggers flood-zone elevation checks and seawall condition reviews that simply don’t exist in inland cities like Coconut Creek. We handle the Broward County submittal, the HVHZ wind-load documentation, and the marine-grade material specs required for salt-air exposure. Our Home Additions & ADU team prices the full permitting path in writing before design hours are billed - Clause 1 of The Haven Standard.
Garage Conversion ADU
This is our most common Lighthouse Point request, and it’s where the hidden conditions live. We pulled permits for a garage conversion ADU off a canal-front lot in the 1958-1975 CBS stretch of Lighthouse Point, and as soon as the walls opened the rough-in inspection turned up aluminum branch wiring and a subfloor over an undersized original slab. Because our contract carried written allowances for electrical and framing, the upgrade was priced as a change order and approved in writing before we touched it - no surprise invoice at the punch list. We also had to fold in a flagged seawall section that the county caught during the same permit review, plus HVHZ impact-rated openings and marine-grade fasteners throughout to survive the salt air. A typical garage conversion ADU in Lighthouse Point runs $30,000-$80,000.
New Detached ADU
Detached ADUs on Lighthouse Point’s tight, seawall-bounded lots require precise siting to maintain canal setbacks and septic/drainage clearances. We work with engineered foundation plans that account for the high water table common to this barrier-island geography, and we specify impact-rated windows and doors from vetted brands that meet HVHZ standards. The foundation alone often demands more than an inland ADU would - pier and grade-beam systems or elevated slabs that handle both flood-zone requirements and the lateral loads of hurricane-force winds.
Junior ADU & Interior Conversion
Junior ADUs - self-contained units within the existing footprint - are popular in Lighthouse Point’s original mid-century homes where lot coverage limits prevent expansion. These conversions almost always open walls built to 1960s codes, and we find the same pattern: aluminum wiring, ungrounded outlets, framing that won’t carry current roof loads, and waterproofing that’s failed behind stucco. We inspect before we quote, document what we find with photos, and write allowances into the contract so every upgrade is priced and signed off before demolition starts.

AfterTrusted Brands We Service in Lighthouse Point
Our sourcing depth across fifty-plus vetted brands means the written quote you receive carries honest numbers rather than inflated ones. For Lighthouse Point’s HVHZ requirements, we regularly specify ViewLux impact-rated windows, Barrette aluminum fencing and railing systems, and Master Halco structural hardware rated for marine environments. We stock common sizes and fasteners locally for Lighthouse Point projects, which keeps lead times short when a permitted inspection reveals a needed upgrade. Ameristar gate systems and marine-grade hardware round out the specifications we write for canal-front properties where standard-grade materials corrode prematurely.
Common Home Additions & ADU Problems We See in Lighthouse Point Homes
- Aluminum wiring and ungrounded rough-ins behind original CBS walls. Open a 1960s Lighthouse Point wall and you’ll often find aluminum branch wiring that failed inspection the moment the permit was pulled. We price the rewiring as a written allowance before demolition, not as a change-order surprise.
- Undersized framing that doesn’t meet current HVHZ wind-load requirements. The original 1958-1975 construction was built to looser codes. Once walls are open, Broward County requires current roof-attachment methods and load-path continuity - we engineer the upgrade and price it in writing before we cut.
- County-flagged seawalls past their 50-year service life. Many of the original poured-concrete seawalls installed during the city’s 1960s buildout are now failing. Broward County inspectors routinely flag them when homeowners pull permits for unrelated renovations, forcing seawall repair or replacement into projects that began as simple additions.
- Salt-air corrosion of standard-grade fasteners and flashing. The dense canal grid means persistent salt-air exposure accelerates corrosion of reinforcing steel, fasteners, and flashing. We write marine-grade material specs into every Lighthouse Point scope from day one.

FAQs - Home Additions & ADU in Lighthouse Point
Because nearly every Lighthouse Point lot sits on or within steps of a navigable canal, construction here intersects with seawall condition checks, flood-zone elevation requirements, and marine-grade material specifications that simply never surface on inland Broward jobs. HVHZ impact-rated openings and salt-air-rated fasteners add material cost, and county-mandated seawall repairs can add $15,000-$60,000 to a project that started as a simple room addition. Call (754) 714-6540 for an exact quote - estimates are free.
Broward County inspectors routinely flag 1960s-era poured-concrete seawalls that are past their 50-year service life when a homeowner pulls any permit, including for garage conversions. The seawall repair or replacement becomes a condition of the permit approval, not optional. We inspect seawall condition during our initial site visit and write allowances into the contract so the cost is priced and approved in writing before work begins. Call (754) 714-6540 for an exact quote - estimates are free.
We inspect before we quote, document existing conditions with photos, and write specific allowances into the contract for the upgrades we know are likely - aluminum wiring replacement, framing reinforcement, marine-grade fasteners. No change proceeds without a signed change order. This is the administrative discipline Haven acquired Rowan for, and it’s why our projects finish within a few percent of the agreed price across 4,000-plus jobs. Call (754) 714-6540 for an exact quote - estimates are free.
Yes. All Lighthouse Point construction falls under Florida’s High Velocity Hurricane Zone code - the most stringent wind-resistance standard in the country - requiring impact-rated openings and specific roof-attachment methods on every permitted project. We specify these from the first written quote, not as an upgrade. Call (754) 714-6540 for an exact quote - estimates are free.
Broward County requires plan review, seawall condition verification, flood-zone elevation compliance, and multiple inspections: rough-in, framing, insulation, and final. We handle all submittals and scheduling, and every inspection visit includes a documented photo record as standard - included, not optional. The full process typically adds 4-8 weeks to the construction timeline. Call (754) 714-6540 for an exact quote - estimates are free.
