AfterFast, Reliable Home Additions & ADU Across Sunrise
Home additions and ADU construction in Sunrise typically run $45,000-$130,000 for room additions and $90,000-$220,000 for detached ADUs, with most projects taking four to eight months from permit application to final inspection. We’re Rowan Construction Group, and our crews work Sunrise’s 1970s-era CBS homes, mid-rise condominiums, and western lots backing up to the Water Conservation Areas. Dispatch and scheduling are coordinated from our Miami office, but the crew that quotes your job is the crew that builds it. Call (754) 254-7676 to schedule your free estimate.
Why Rowan Construction Group Fort Lauderdale Is Sunrise’s Preferred Home Additions & ADU Company
We’ve delivered more than 4,000 projects since 2007, every one with a written price before work started and a documented photo record when the crew left. Sunrise homeowners find us because they read the three-star reviews and want to see the line-item numbers before they make contact.
Our Home Additions & ADU team knows the local building department’s review sequence, the dewatering details the western lots require, and the HOA packet gaps that stall permits in 1970s-era communities like Sunrise Lakes. That local knowledge keeps calendars predictable.
Under Clause 1 of The Haven Standard, the price is written before anyone starts. No change proceeds without a signed change order. Our projects finish within a few percent of the number the customer agreed to. The 365-Day Done Right Promise is printed on every page, backed by terms, not an asterisk.
Calls are answered by a live person 24/7. Crews are background-checked and uniformed. Every visit includes a documented photo record, included as standard.
Our Home Additions & ADU Services in Sunrise
ADU Design & Permitting
We handle the full submittal packet for Sunrise ADUs, including the dewatering and drainage details the city building department requires for western lots near the Water Conservation Areas. Site plans without this detail get kicked back before structural review begins, adding weeks to a calendar we already build around weather and material lead times. Our packet includes the footing schedule revised for shallow groundwater, the architectural drawings, and the HOA documentation where applicable. A typical ADU design and permitting cycle in Sunrise runs $90,000-$220,000 all-in.
Garage Conversion ADU
Garage conversions in Sunrise’s single-family CBS neighborhoods run $30,000-$80,000 and use the existing slab and roof structure, which simplifies permitting but still requires full architectural review through the city. The conversion needs the same permits as a detached ADU for electrical, plumbing, and occupancy, plus tie-in to the main home’s HVAC or a dedicated mini-split system. We see this option most often in the single-family pockets between Oakland Park Boulevard and Sunrise Boulevard, where 1980s ranch homes have attached two-car garages with adequate headroom for a junior unit.
New Detached ADU
Detached ADUs in Sunrise face the strictest site-plan scrutiny because of the shallow water table. We pulled a Broward County owner’s build permit for a detached ADU in Sunrise’s Sunrise Lakes corridor where the lot backed up to a canal-maintained swale, and our site plan was returned by the city for lack of a dewatering detail showing the shallow water table at 2-3 feet below grade. We resubmitted with a dewatering plan and a revised footing schedule, and the inspection sign-off on the rough-in passed first time. That approval sequence added three weeks to a calendar we had already built around weather and material lead times. New detached ADUs in Sunrise run $90,000-$220,000.
Junior ADU & Interior Conversion
Junior ADUs work inside the existing footprint, converting a portion of the main home into a separate unit with its own entrance. In Sunrise’s older CBS homes, this often means reconfiguring the floor plan around the existing load-bearing walls, not adding square footage. The permitting is simpler than detached construction, but the city still requires full architectural review for egress, fire separation, and utility tie-ins. Junior ADUs in Sunrise typically fall within the $45,000-$130,000 range depending on whether the project includes kitchen and bath rough-in.

AfterTrusted Brands We Service in Sunrise
We source across fifty-plus vetted brands so the written quote carries honest numbers. For roofing tie-ins on second-story additions and ADUs in Sunrise, we specify GAF and Owens Corning shingles with proper wind-mitigation fastening patterns that meet post-Andrew code requirements. On window packages for garage conversions and junior ADUs, we use CertainTeed and IKO where the project calls for impact-rated units. We do not inflate the quote with brands you did not ask for. The price in writing reflects the spec in writing.
Common Home Additions & ADU Problems We See in Sunrise Homes
- Plan-review rejections for missing dewatering detail. Sunrise’s western lots sit on Broward County’s shallowest water table, and the city building department returns site plans for detached ADUs and additions that do not show drainage and dewatering at 2-3 feet below grade. We build this detail into every submittal.
- Height and eave-line mismatches after city approval. Starting foundation or slab work before architectural review finishes means discovering the approved dimensions differ from what was built, forcing change orders and partial demolition. We do not break ground until the signed permit is in hand.
- HOA packet gaps in 1970s-80s communities. Sunrise Lakes and similar complexes often have incomplete architectural-committee records after decades of waived reserves. We verify every required HOA signature block before filing the city packet, not after.
- Stucco spalling and flat-roof membrane failure on tie-ins. Sunrise’s 60-inch annual rainfall, concentrated June through October, accelerates envelope failure on 1970s-80s building stock. We inspect the existing substrate condition before quoting the addition connection, and we document what we find with photos.

FAQs - Home Additions & ADU in Sunrise
Architectural review through the Sunrise building department typically adds four to six weeks for a complete submittal, and an additional two to three weeks if the plan is returned for dewatering or drainage detail on western lots. We build this into the project calendar before any material is ordered or crew is scheduled, so the job does not sit unfinished waiting on a committee. Call (754) 254-7676 to schedule your free estimate.
We do. Rowan Construction Group prepares and files the complete submittal, including architectural drawings, structural calculations, dewatering plans for qualifying lots, and HOA documentation where required. The customer receives a copy of every filing and every response. Under Clause 1 of The Haven Standard, no work starts until the permit is issued and the price is written.
Sunrise’s architectural review focuses on compatibility with existing neighborhood character, which in practice means stucco or painted CBS exteriors, shingle or flat membrane roofs matching the main structure, and heights that do not exceed the existing ridge line on single-family homes. Condo and HOA communities often have stricter covenants. We research the specific requirements for your property before submitting, not after. Call (754) 254-7676 for a free estimate.
Yes, for the occupied portion. A garage conversion requires the same electrical, plumbing, mechanical, and occupancy permits as a detached ADU, though it may use the existing slab and roof structure if they meet current code. The city still requires full architectural review for egress, fire separation, and utility connections. The permit path is shorter than new detached construction, but it is not a handyman exemption.
The shallow water table, at 2-3 feet below grade in western Sunrise neighborhoods, turns routine footing work into a dewatering operation. We specify a revised footing schedule and active dewatering during excavation, and we document the groundwater depth in the site plan submittal. Without this detail, the city returns the plan before structural review begins. We learned this on a Sunrise Lakes corridor project where our initial submittal was kicked back, and we now include dewatering documentation on every western lot. Call (754) 254-7676 for an exact quote on your site.
