AfterFast, Reliable Home Additions & ADU Across Lauderdale Lakes
Home additions and ADU construction in Lauderdale Lakes typically run $45,000-$130,000 for attached room additions and $90,000-$220,000 for detached accessory dwelling units, with most projects taking 3-6 months from permit to final inspection. We’re Rowan Construction Group, and our crews work the Lauderdale Lakes market weekly - dispatch and scheduling run through our Miami office, but the trucks that show up at your door know the difference between a 1968 CBS garden apartment off NW 31st Ave and a 1974 condo near the Boulevard. Call (754) 714-6540 to schedule your free estimate; we’ll put a written price in your hand before anyone picks up a tool.
Why Rowan Construction Group Pompano Beach Is Lauderdale Lakes’s Preferred Home Additions & ADU Company
We’ve built our reputation in Lauderdale Lakes on one thing other contractors treat as optional: documentation. Every project since our founding in 2007 has started with a flat written price and a written scope, and every visit produces a photo record the customer keeps. That discipline matters especially here, where the housing stock - dense 1960s-70s CBS garden apartments and small condominiums - hides conditions that out-of-area bidders routinely miss.
Our crews are background-checked, uniformed, and briefed on Broward County’s specific inspection protocols before they arrive. A live person answers our phones 24/7, and estimates are delivered in writing, not over a voicemail. We don’t promise speed we can’t document; we promise a process that keeps your project within a few percent of the number you agreed to. That’s Clause 1 of The Haven Standard, and it’s printed on every contract we sign in Lauderdale Lakes.
Grant Rowan has led this company since 2007, and the administrative discipline Haven acquired Rowan for - signed change orders, no exceptions - is the same reason we’ve delivered 4,000-plus projects without the cost overruns that plague this industry.
Our Home Additions & ADU Services in Lauderdale Lakes
Room Additions
A room addition in Lauderdale Lakes usually means tying into an existing CBS wall built during the Johnson administration. We don’t assume that wall is clean block. On a recent project off NW 31st Ave, our crew opened a 1968 two-story garden apartment for a rear addition and found carbonated block with exposed, oxidized rebar at the tie-in beam - plus original 100-amp service and galvanized supply lines still in service. We stopped work, wrote a change order for a 200-amp rough-in and epoxy-coated rebar splice, priced it in writing, and reset the draw schedule. The addition closed clean because nothing got touched until the fix was approved. That’s how we handle room additions in Lauderdale Lakes: inspect first, price the surprises before they become emergencies.
New Detached ADU
Detached ADUs in Lauderdale Lakes face a constraint most Broward cities don’t: tight urban lot configurations left over from 1960s garden-apartment planning, where equipment staging space is minimal and the seasonal water table sits close to grade. Footer excavation scheduled into the May-October wet season can hit standing water or soft spots that cave overnight. We price Lauderdale Lakes ADU foundations with geotechnical allowances built in, and we don’t pour until the soil conditions are documented. A typical new detached ADU in Lauderdale Lakes runs $90,000-$220,000, and we deliver that range in writing before the first shovel breaks ground.
ADU Design & Permitting
Permitting an ADU in Lauderdale Lakes means navigating Broward County’s building code enforcement alongside Florida’s post-Surfside SB-4D structural integrity mandates - a dual compliance environment that out-of-area designers often underestimate. Our Home Additions & ADU team prepares permit packages that account for the existing building’s milestone inspection status from day one. If your property is already under SB-4D repair orders, we coordinate the ADU scope with the structural remediation so neither permit holds up the other. The design fee is quoted flat, and the permit timeline is written into the contract.
Garage Conversion ADU
Garage conversions in Lauderdale Lakes run $30,000-$80,000, but the real variable isn’t the garage - it’s what the garage is attached to. Many of these structures share a roof plane with the main building, and if that roof has been re-layered two or three times over the decades (common here), local permit inspectors will flag the Florida Building Code’s two-layer maximum before any conversion permit closes. We inspect the roof assembly before we quote, not after we start. That single step has saved our Lauderdale Lakes customers from the full tear-off surprises that blindside less thorough bidders.
Junior ADU & Interior Conversion
Junior ADUs - conversions within the existing footprint, often with a separate entrance added - work best in Lauderdale Lakes’s smaller single-family stock near the Boulevard. The challenge is usually the electrical panel: original 100-amp service can’t handle a second kitchen, second bath, and independent HVAC. We price the panel upgrade into the initial quote, not as a change order after the rough-in fails inspection.
ADU Site Prep & Utilities
Utility trenching in Lauderdale Lakes runs through sandy, high-water-table soil that can slump during the wet season. We schedule underground work for the drier months when possible, and we specify dewatering allowances in the contract when it’s not.
Second Story Additions
Second stories on Lauderdale Lakes’s aging CBS structures require structural verification of the existing footings and load-bearing walls - a step we never skip. The SB-4D inspection documentation often gives us a head start on what we’ll find.
Sunrooms & Enclosed Patios
Enclosed patios in Lauderdale Lakes need impact-rated glazing and proper positive pressure design for hurricane compliance. We specify Kohler fixtures and Moen hardware where plumbing is involved, and we document the wind-load rating on every enclosure.

AfterTrusted Brands We Service in Lauderdale Lakes
Our written quotes carry honest numbers because we source across fifty-plus vetted brands, not a single supplier’s catalog. For Lauderdale Lakes additions and ADUs, we regularly specify Kohler and Moen plumbing fixtures, Caesarstone and Silestone surfacing for kitchenettes and wet bars, and GAF or Owens Corning roofing where the project includes a new roof plane or tie-in. We stock common repair parts locally for faster turnaround on warranty calls, and every brand name in your quote is available for you to inspect at a showroom before work starts. No substitutions happen without a signed change order.
Common Home Additions & ADU Problems We See in Lauderdale Lakes Homes
- Carbonated CBS block with oxidized rebar at tie-in points. Lauderdale Lakes’s 1960s-70s concrete block structures have spent six decades in humidity that accelerates carbonation. When we open a wall for an addition, we expect to find degraded block, not clean substrate - and we price for it upfront.
- Original 100-amp electrical panels and galvanized plumbing still in service. These systems fail rough-in inspection the moment an ADU adds a second kitchen and bath. We verify panel capacity and supply line material before we quote, not after the inspector tags it.
- Roof assemblies exceeding Florida Building Code’s two-layer maximum. Many Lauderdale Lakes garden apartments have been re-roofed in place two or three times. Local permit inspectors catch this every time, forcing a full tear-off and deck inspection that out-of-area contractors never priced.
- Wet-season excavation failures on high-water-table lots. Lauderdale Lakes’s flat, low-lying interior sees seasonal water tables rise close to grade. Footer trenches dug May through October can cave or fill overnight. We schedule around it or specify dewatering in the contract.
Pricing for Home Additions & ADU in Lauderdale Lakes, FL
Here’s what a written quote from Rowan Construction Group actually looks like for Lauderdale Lakes:

| ADU Construction (new detached unit) | $90,000-$220,000 |

These ranges reflect real Lauderdale Lakes conditions: the density of aging CBS stock under SB-4D inspection pressure, the prevalence of hidden structural repair needs at tie-in points, and the wet-season constraints on foundation work. Your final written price depends on what we find during site inspection - panel capacity, roof layer count, soil conditions, and the structural status of existing walls. We build allowances into the contract for discoverable conditions, and any surprise is priced and approved in writing before we touch it. Under Clause 1 of The Haven Standard, the price is written before anyone starts. Call (754) 714-6540 for your free estimate.

FAQs - Home Additions & ADU in Lauderdale Lakes
Because the first quote often assumes clean block, adequate electrical service, and a roof that passes permit inspection - conditions that are the exception, not the norm, in Lauderdale Lakes’s 1960s-70s housing stock. Out-of-area contractors bid off a visual walk, miss the carbonated CBS and oxidized rebar at the tie-in, then deliver unbudgeted change orders after the wall is open. We inspect first and write allowances into the contract. Call (754) 714-6540 for an exact quote - estimates are free.
Yes. Lauderdale Lakes sits on flat, low-lying interior Broward County land where the seasonal water table rises close to grade from May through October. Footer trenches can fill with standing water or cave overnight, forcing rework that was never in the original scope. We schedule excavation for drier months when possible, and specify dewatering equipment in the contract when it’s not. Call (754) 714-6540 to discuss timing for your project.
The two-roof-layer maximum in the Florida Building Code. Many older Lauderdale Lakes garden apartments have been re-roofed in place two or three times over the decades. Local permit inspectors catch this on every addition permit, forcing a full tear-off and deck inspection before the new work can close. We inspect the roof assembly before we quote, so this isn’t hidden. Call (754) 714-6540 for a permit-ready assessment.
We assume carbonated block with rebar oxidation until inspection proves otherwise. On a 1968 garden apartment off NW 31st Ave, we found exactly that - plus outdated electrical and galvanized plumbing - and stopped work to write a priced change order for epoxy-coated rebar splice and 200-amp service before proceeding. Nothing gets touched until the fix is approved in writing. That’s the Haven Standard discipline that keeps projects within a few percent of the agreed price. Call (754) 714-6540 to schedule your site inspection.
Broward County Building Code Division handles permitting, with additional SB-4D structural integrity documentation required if your building is under milestone inspection orders.
