Why Rowan Construction Group Fort Lauderdale Is Oakland Park’s Preferred Home Additions & ADU Company
We’ve delivered written quotes on over 4,000 projects since 2007, and a significant share of our recent work has been in Oakland Park’s pre-1992 housing stock. Our Oakland Park customers leave reviews that mention the same things: the photo record they received at every visit, the signed change order before any surprise work, and the final invoice within a few percent of the written price they agreed to. We don’t ask for trust; we document the work.
Response time to Oakland Park is typically same-week for initial site visits, with estimates delivered in writing within 48 hours of measurement. Our crews know the local permitting rhythm - Broward County’s HVHZ requirements, the FEMA AE flood zones along Middle River tributaries, and the specific base flood elevation thresholds that stall less experienced contractors. That familiarity saves weeks on the schedule.
Grant Rowan built this company on Clause 1 of The Haven Standard: a written price before any work starts, every time. In Oakland Park, where a 1960s CBS home can conceal cloth wiring, undersized headers, or stem walls below flood elevation, that discipline matters more than anywhere.
Our Home Additions & ADU Services in Oakland Park
New Detached ADU
A detached ADU in Oakland Park starts around $90,000 and can reach $220,000 depending on size, utility tie-ins, and the flood-zone status of your parcel. On canal-fronting lots near Middle River, we engineer for the parcel’s specific base flood elevation from day one - pier-and-beam or raised stem-wall construction priced into the initial quote, not discovered at permitting. Our Home Additions & ADU team handles the full arc: site plan, structural engineering for HVHZ wind loads, Broward County permitting, and utility rough-in to the main house.
Second Story Additions
Second story additions on Oakland Park’s 1950s-1970s CBS homes demand a structural inspection before we quote. The original footings and stem walls were sized for a single story, and many lack the continuous load path that post-1992 code requires. We open the wall, photograph what we find, and price the reinforcement - engineered beams, hurricane strapping, potential footing augmentation - as written allowances before demolition begins. A second story addition in Oakland Park typically falls in the $45,000-$130,000 range, with structural retrofits itemized separately so you see where every dollar goes.
Garage Conversion ADU
Garage conversion ADUs run $30,000-$80,000 in Oakland Park and represent one of the faster paths to rental income or multigenerational housing. The catch: Broward County classifies these as dwelling unit conversions, which triggers full HVAC, electrical panel, and impact-opening compliance. We pull the permit as part of scope, never as an afterthought. On a recent job near Oakland Park Boulevard, we found the garage slab sat below the parcel’s base flood elevation - we priced the stem-wall raise and new flood-vent installation in the original quote, and the client approved it before we cut the first stud.
ADU Design & Permitting
Every Oakland Park ADU we design opens with a site survey that flags the three local variables that move budgets: HVHZ wind-load engineering, FEMA flood zone classification, and the condition of the existing home’s electrical and structural systems. We don’t produce conceptual drawings that crumble at plan review. Our permit packages include engineered structural plans, energy calculations, and flood-proofing documentation ready for Broward County’s building department.
Junior ADU & Interior Conversion
Junior ADUs - self-contained units within the existing footprint - work well in Oakland Park’s smaller CBS homes where lot coverage limits prevent detached construction. We separate utilities where code requires, add kitchenette and bath rough-in, and ensure the unit meets egress and ventilation standards. Pricing typically starts in the lower half of our $45,000-$130,000 home addition range.
Room Additions & Sunrooms
Single-room additions and enclosed patios in Oakland Park must match the existing home’s CBS construction and meet HVHZ impact standards for any new openings. We specify CWS, ES Windows, or ECO Window Systems impact-rated products as standard, not upgrades, and we price the full envelope - roof tie-in, wall integration, and floor system - as a single written scope.

AfterTrusted Brands We Service in Oakland Park
We source across fifty-plus vetted brands, and for Oakland Park’s HVHZ requirements we stock and specify impact-rated windows and doors from CWS, ES Windows, and ECO Window Systems - brands that carry the Miami-Dade and Broward County product approvals required for permit sign-off. For ADU kitchen and bath packages, we quote KraftMaid and Wellborn cabinetry, Cambria and Caesarstone countertops, and Kohler and Toto fixtures with local supplier relationships that keep lead times predictable. Every brand is named in your written quote with model numbers and specifications, so the price you compare is an apples-to-apples number.
Common Home Additions & ADU Problems We See in Oakland Park Homes
- Cloth wiring behind CBS walls. The 2-wire cloth-insulated circuits common in pre-1970s Oakland Park homes won’t carry the load of a modern addition. We find it during pre-demo inspection, price the panel upgrade and rewiring as a written allowance, and execute only after your signed approval.
- Undersized or missing footings under original stem walls. A 1960s CBS ranch in Coral Heights wasn’t built to carry a second story. We expose the footing, photograph the condition, and engineer a solution - pier-and-beam reinforcement or new continuous footing - priced before we proceed.
- Stem walls below base flood elevation on Middle River canal lots. FEMA AE zones cover much of Oakland Park’s waterfront. We order the elevation certificate during design, price the compliant foundation work in the original quote, and avoid the permitting stall that traps contractors who guess.
- HVHZ impact-opening and strapping treated as add-ons instead of core scope. Every new window, door, and roof connection in Oakland Park must meet High Velocity Hurricane Zone standards. We engineer for this from the first inspection, not as a change order after framing - which is why our inspection sign-offs stay on schedule.

FAQs - Home Additions & ADU in Oakland Park
Oakland Park’s pre-1992 CBS housing stock sits inside Broward County’s HVHZ, so nearly every addition or ADU must be engineered and strapped to high-velocity hurricane-zone wind-load requirements - a retrofit burden that newer inland suburbs to the west, built under the post-1992 code, never face. Flood zone compliance on Middle River canal lots adds elevation certificates and raised foundation work that flat, inland parcels don’t require. Call (754) 254-7676 and we’ll walk through your parcel’s specific code requirements with a free estimate.
Yes, but the ADU must be constructed with its lowest floor at or above the parcel’s base flood elevation, which typically requires pier-and-beam or raised stem-wall foundation systems. We order the elevation certificate during design and price the compliant foundation in your original written quote, not as a surprise at permitting. Call (754) 254-7676 to schedule a site evaluation.
On a canal-fronting lot off a Middle River tributary in the Coral Heights area, we opened the rear wall of a 1960s CBS ranch for a 400 sq ft primary suite addition and found the original 2-wire cloth wiring, an undersized header over the old slider, and a stem wall sitting below the parcel’s base flood elevation. We priced the electrical rough-in, the new engineered beam, and the elevation-compliant stem wall as written allowances before demo, then issued a single change order for the structural work - the client approved it in writing before we touched a stud, and we threaded the whole scope through Broward County permits without a stall. That’s our standard process on every Oakland Park job of that era. Call (754) 254-7676 for a free inspection and written quote.
Yes. Broward County classifies garage conversion ADUs as dwelling unit changes of occupancy, which requires full building, electrical, plumbing, and mechanical permits - plus compliance with HVHZ impact-opening standards and flood zone requirements if applicable. We pull all permits as part of scope; the permit cost is itemized in your written quote. Call (754) 254-7676 to start the process with a free estimate.
We inspect before we quote, photograph what we find, and write every potential variable into the contract as a priced allowance - cloth wiring, structural reinforcement, flood-zone foundation work. If conditions match the allowance, the price holds. If we find something worse, we issue a signed change order before touching it. That discipline, inherited from Haven’s acquisition of Rowan in 2007, is why our projects finish within a few percent of the agreed price across 4,000-plus jobs. Call (754) 254-7676 for a free estimate with written allowances built in.
