AfterFast, Reliable Home Additions & ADU Across Hollywood
A home addition in Hollywood typically runs $45,000-$130,000, while a full detached ADU runs $90,000-$220,000, with permits and site prep included in our written quote. For Bathroom Remodeling in Hollywood, we apply the same coastal-spec standards. ADU construction and room additions in Hollywood face a material challenge that inland Broward contractors often miss: salt air from the Atlantic and Intracoastal corrodes standard hardware within years, so coastal-spec fasteners, sealed joints, and marine-grade finishes are not upgrades here. They’re the baseline for a structure that lasts. Our crews serve Hollywood from our Miami office, and we’ve worked from Hollywood Hills to the Hollywood Beach corridor since 2007. Call (754) 254-7676 to schedule your free estimate.
Why Rowan Construction Group Fort Lauderdale Is Hollywood’s Preferred Home Additions & ADU Company
We’ve delivered more than 4,000 projects across South Florida, and a growing share of them are in Hollywood - from garage conversions near Young Circle to second-story additions in Hollywood Hills and new detached ADUs west of I-95. Our Hollywood customers leave reviews that mention the same thing: the written price matched the final invoice, and the photo record showed exactly what happened on their property.
What separates our work here is local field knowledge. We know that a 1960s CBS home in Hollywood Hills needs different structural tie-ins than a 1980s condo on A1A. We know that FEMA flood zones AE and VE cover large sections of the city, triggering freeboard requirements that inland contractors from Plantation or Margate may not anticipate. And we know that Hollywood Beach’s 1970s post-tensioned towers demand ground-penetrating radar before any slab penetration - a step some crews skip.
Our calls are answered by a live person 24/7. Crews are background-checked and uniformed. Every visit produces a documented photo record, included as standard. Under Clause 1 of The Haven Standard, your written price arrives before any work starts. Under the 365-Day Done Right Promise, if it is not done right, we make it right - backed by terms, not a handshake.
Our Home Additions & ADU Services in Hollywood
New Detached ADU
A new detached ADU in Hollywood runs $90,000-$220,000, with final cost driven by site conditions, utility tie-ins, and flood zone compliance. Much of Hollywood sits 6-10 feet above sea level in FEMA AE or VE zones, so new construction often requires freeboard elevation and sometimes a full floodplain variance review. We handle the permit package, the soil evaluation, and the structural design. Our ADU specs for Hollywood include impact-rated openings and sealed paver joints - the salt environment here destroys standard joint sand and corrodes inland-spec railings within a few years.
Second Story Additions
Second story additions in Hollywood’s older neighborhoods - Hollywood Hills, Emerald Hills, areas near Stirling Road - face a structural reality: many 1950s-1970s CBS homes were built before hurricane straps were code, and the roof-to-wall connection needs retrofit before load increases. We assess the existing structure, specify the strap and tie-down package, and quote it flat. On the Hollywood Beach corridor, second-story work often means tying into a post-tensioned slab, where GPR scanning is non-negotiable. We locate every tendon before layout. The alternative is catastrophic failure, and we have seen the aftermath of crews who skipped this step.
Room Additions
Room additions in Hollywood - whether a master suite expansion in West Lake or a living room extension near Hollywood Boulevard - typically fall in the $45,000-$130,000 range depending on square footage, foundation type, and finish level. Slab-on-grade additions in flood-prone areas need elevation compliance. Second-story additions need structural verification. We specify coastal-grade materials as standard: stainless or hot-dip fasteners, marine-grade aluminum or vinyl window frames from our Home Additions & ADU supplier network, and waterproofing membranes rated for salt-air exposure. The price gap between coastal-spec and inland-spec is real - usually 8-15% on hardware and finishes - but standard zinc or galvanized fasteners show rust within two to three years here. The cheap spec costs more.
Garage Conversion ADU
Garage conversion ADUs in Hollywood run $30,000-$80,000. The existing slab, ceiling height, and setback compliance determine feasibility. Hollywood’s zoning allows ADUs in many residential districts, but the conversion must meet current Florida Building Code for egress, insulation, and HVAC. We pull the permit, coordinate the inspection schedule, and deliver a written scope that includes every line item. If the garage sits in a flood zone, elevation and utility routing may add complexity - we flag this in the initial site visit, not mid-project.
ADU Design & Permitting
Our design and permitting service handles the full package: site plan, structural drawings, MEP coordination, and submission to Hollywood’s Building Division. We know the local review timeline and the common kickback items - setback calculations, parking replacement, landscape compliance - and we address them before submission to avoid delays.
Junior ADU & Interior Conversion
Junior ADUs and interior conversions work within the existing envelope, often at lower cost than detached units. We assess load-bearing walls, egress windows, and utility routing. In Hollywood’s older CBS homes, we frequently find unpermitted prior work that needs resolution before new permits issue - we document it, quote the correction, and handle the compliance path.
ADU Site Prep & Utilities
Site prep in Hollywood can involve fill soil, high water table conditions, or utility extensions across setback lines. We coordinate the civil work, the sewer and water tie-ins, and the electrical service upgrade. Every step is photographed and documented.
Sunrooms & Enclosed Patios
Sunrooms and enclosed patios extend living space without full addition cost. We specify impact-rated glazing for Hollywood’s wind zone and aluminum framing with marine-grade finishes. The enclosure must meet Florida Building Code for wind load and, in flood zones, elevation requirements.

AfterTrusted Brands We Service in Hollywood
Our written quotes draw from fifty-plus vetted brands so the numbers are honest, not inflated. For Hollywood’s coastal environment, we specify ES Windows and ECO Window Systems for impact-rated openings - their marine-grade finishes hold up to salt air better than standard anodized frames. For exterior hardware on additions and ADUs, we source stainless and hot-dip galvanized fasteners; standard zinc plating fails prematurely here. We stock local inventory for common items, which keeps turnaround tight when a Hollywood project needs a replacement or change. Every brand is named in the written scope, so you know exactly what you’re buying.
Common Home Additions & ADU Problems We See in Hollywood Homes
- Post-tensioned slab damage from un-scanned cutting. Many 1970s Hollywood Beach and Intracoastal towers used post-tensioned concrete slabs. Cutting for plumbing rough-in or structural tie-in without GPR scanning risks severing a tendon, causing immediate, irreversible structural failure. We scan every time.
- Galvanized fastener corrosion on coastal additions. Standard zinc or galvanized hardware looks fine at completion. Within two to three years in Hollywood’s salt air, rust streaks appear. We specify stainless or hot-dip as standard, not as an upgrade.
- Non-sealed paver joint failure near the Intracoastal. Chloride exposure breaks down standard joint sand and attacks aluminum railings. Our coastal-spec additions use sealed joints and marine-grade finishes.
- Flood zone compliance gaps. Large sections of Hollywood are in FEMA AE and VE zones. Contractors unfamiliar with Broward’s floodplain administration may miss freeboard requirements or variance triggers, killing a permit or triggering mid-project redesign. We verify zone status before quoting.

FAQs - Home Additions & ADU in Hollywood
Yes. The salt air within a few miles of the Atlantic or Intracoastal corrodes standard galvanized or zinc-plated hardware within two to three years, and non-marine aluminum frames show pitting and seal failure. We specify stainless or hot-dip fasteners and marine-grade window finishes as standard on Hollywood Beach projects. The upfront cost gap is 8-15%, but replacing corroded hardware mid-life costs far more. Call (754) 254-7676 for a written quote that names every material spec.
The risk is catastrophic and irreversible structural failure. Post-tensioned slabs contain high-stress steel tendons; severing even one can compromise the entire floor system. On a 1968 poured-concrete condo in the Hollywood Beach corridor, our crew needed to core through a post-tensioned slab for a second-story addition’s rough-in; ground-penetrating radar located every tendon before we marked the layout, and we switched the exterior scope to stainless fasteners and sealed paver joints because inland-spec galvanized hardware was already showing corrosion in the salt air. The result: a clean inspection sign-off with no tendon compromise. Call (754) 254-7676 - we scan before we cut, every time.
Much of Hollywood sits at 6-10 feet above sea level in FEMA AE and VE flood zones, which triggers mandatory freeboard elevation requirements for new construction and substantial renovations. Some projects require full floodplain variance review through Broward County. We verify zone status during the initial site visit and factor compliance into the permit package and quote. Call (754) 254-7676 for a free estimate that includes flood zone analysis.
Inland contractors often specify standard hardware, skip GPR scanning on post-tensioned slabs, and underestimate flood zone compliance. Hollywood Beach’s 1970s towers, salt environment, and layered regulatory history - Broward’s 40-year recertification program plus Florida’s 2022 Condo Safety Law - demand field experience that generalist crews lack. We’ve worked this corridor since 2007. Call (754) 254-7676 for a second opinion on any written estimate.
Yes. All garage conversions and ADUs in Hollywood require permits through the city’s Building Division, including zoning verification, structural plans, and inspections. We handle the full permit package as part of our service. The process typically adds 4-8 weeks to the front end, but starting without a permit triggers stop-work orders and expensive corrections. Call (754) 254-7676 and we’ll walk you through the specific requirements for your property.
