AfterFast, Reliable Home Additions & ADU Across Coral Springs
A room addition or ADU in Coral Springs typically runs $45,000-$130,000 for a standard addition and $90,000-$220,000 for a full detached ADU, with garage conversions landing between $30,000-$80,000. The number most homeowners don’t see coming is the 30-60 day HOA architectural review window that has to clear before Broward County will even accept your permit application. We handle both tracks from day one, so your job doesn’t sit half-open waiting on a committee. Call (877) 610-1318 for a free estimate with a written timeline.
Tom Barrett and his sons run the crews on every Home Additions & ADU job we take in Coral Springs. We file the ARC packet, pull the Broward County permit, coordinate with the South Florida Water Management District where the water table demands it, and price everything in writing before a single nail moves.
Why Barrett & Sons Construction Is Coral Springs’s Preferred Home Additions & ADU Company
Coral Springs is a deed-restricted city, and that changes how additions and ADUs get built here. Nearly every neighborhood from the original Coral Ridge Properties master plan requires architectural review committee sign-off before a county permit gets issued. Most national outfits treat that as your problem. We treat it as step one of the job.
Our name is on the truck. Tom Barrett publishes his name, address, and license number, and our crew members are background-checked and uniformed on every visit to Coral Springs. We answer the phone with a live person 24/7, not a voicemail box or an out-of-state call center. When a Coral Springs homeowner off Wiles Road calls at 7 a.m. with a question about their permit status, a person picks up.
Founded in 1998 and owner-operated from day one, Barrett & Sons has built additions and ADUs across western Broward County for over 29 years. Dispatch and scheduling coordinate from our South FL metro office, and crews serve Coral Springs locally. Every job gets a written scope, written allowances, and a written change order before any price shift happens. We back it with the 90-Day Done Right Promise, printed on every contract.
Our Home Additions & ADU Services in Coral Springs
ADU Design & Permitting
An accessory dwelling unit in Coral Springs almost always needs two approvals before construction starts: your HOA architectural review committee and the Broward County Building Division. We prepare the ARC submittal packet, including elevation drawings, material samples, color swatches, and site plans showing setbacks and drainage. We file it, answer committee questions, revise if needed, then pull the county permit. One team owns both tracks, which is the only way to avoid a permit set that the ARC rejects after the county already approved it.
Garage Conversion ADU
Garage conversions are the most common ADU route in Coral Springs because the footprint already exists, which can shave weeks off the entitlement phase. But many of these CBS structures from the late 1960s through mid-1990s still carry original aluminum single-pane windows and pre-Andrew roof deck nailing. On a west-side subdivision off Wiles Road, we converted a 1980s garage into a permitted ADU, filed the HOA architectural review packet first, then pulled the Broward County permit. The footer excavation hit standing groundwater at three feet, so we coordinated the below-grade sewer tie-in with the South Florida Water Management District drainage easement before the slab was poured. A legal ADU conversion in Coral Springs runs $30,000-$80,000, depending on ceiling height, plumbing rough-in distance, and whether the garage slab meets current code for living space.
New Detached ADU
A detached ADU in Coral Springs runs $90,000-$220,000, and the two biggest cost drivers are site prep and drainage coordination. The high water table on former Everglades flatland means any below-grade footer work needs dewatering and possibly SFWMD easement review. Your HOA will also weigh in on structure height, roof pitch, exterior finish, and position relative to the primary dwelling and property line. We price excavation, dewatering, utility trenching, and ARC revisions as line items in the initial estimate so the number you sign is the number you pay, minus only documented, written change orders.
Junior ADU & Interior Conversion
A junior ADU or interior conversion, such as a finished room over a garage or a re-plumbed back bedroom with a kitchenette, falls under the standard home addition range of $45,000-$130,000 in Coral Springs. These jobs usually trigger less HOA scrutiny because the exterior footprint rarely changes, but the county still wants a permit, and the high water table still matters if you’re adding a bathroom below grade or tying new plumbing into the existing waste line. We pull every permit, schedule every inspection, and keep the exterior weather-tight through the entire build. Never let a contractor open an exterior wall in June before your ARC approval lands. A torn-open wall exposed to a Coral Springs afternoon thunderstorm while the committee clock still runs is a repair bill with no owner.

Trusted Brands We Service in Coral Springs
We install materials you can look up, not mystery brands off a van. For Coral Springs ADU foundations, patio pads, and site hardscape around new structures, we use Techo-Bloc and Cambridge pavers regularly, with Oldcastle and Quikrete products for footers, slabs, and drainage structures. These are engineered products with published specs, which matters when your HOA architectural review committee wants material details before they sign off. We can pull spec sheets for every product line the day your ARC packet goes in.
Common Home Additions & ADU Problems We See in Coral Springs Homes
- Demolition before ARC sign-off. We see homeowners and contractors open up a wall or pour a footer before the HOA architectural review committee has approved the plans. In Coral Springs that’s a 30-60 day window, and an open structure through a June thunderstorm turns a straightforward addition into water remediation.
- Groundwater surprises during excavation. Coral Springs sits on former Everglades flatland with a seasonally high water table. Any below-grade plumbing rough-in or footer work floods overnight if the builder skips dewatering and SFWMD drainage coordination. We plan for water before the excavator shows up.
- ARC rejection after county permit approval. A roof-to-wall strap detail or window style that the county accepts but your Coral Springs HOA architectural review committee rejects forces a full resubmittal and a second review cycle. We sequence the ARC review first on every exterior-visible project so the permit package matches what the committee already approved.
- Pre-code structural surprises in older CBS homes. Many 30-55 year old Coral Springs homes have original roof deck nailing, single-pane aluminum windows, and flat-membrane roofs that don’t meet current wind-load code. Once an addition ties into the existing structure, the county may require upgrading the connecting portion. We flag that in the estimate before it becomes a surprise.

FAQs - Home Additions & ADU in Coral Springs
Plan for 30-60 days of HOA architectural review committee time before the Broward County permit can be pulled, so on top of county permit review and construction, a Coral Springs addition or ADU carries a built-in 1-2 month entitlement window that neighboring unincorporated Broward or Margate jobs don’t have. We file the ARC packet first, run the county permit in parallel where the county allows, and schedule construction around the approval date so you’re not paying for a crew standing idle. Call (877) 610-1318 for a timeline specific to your neighborhood.
Yes, if it meets Broward County code for living space (minimum ceiling height, egress, separate entrance, kitchen and bath requirements) and clears both your HOA’s architectural review and the county’s zoning approval. A permitted legal ADU in Coral Springs runs $30,000-$80,000 for a garage conversion, and the permit is what makes it legal rental space. We handle the ARC packet, the county permit, and every inspection. Call (877) 610-1318 to find out if your garage qualifies.
Coral Springs deed restrictions from the original Coral Ridge Properties master plan generally favor stucco finishes, barrel tile or flat concrete roof profiles that match the surrounding structures, and neutral exterior color palettes already established in your subdivision. Your HOA’s architectural review committee wants the addition to look like it belonged to the original 1970s-1990s plan, not like a new build dropped onto an older lot. We match elevations, rooflines, and finish materials to your existing home and the committee’s published standards, then file the submittal packet with everything they need to approve it in one round. Call (877) 610-1318 and we’ll walk you through what your specific HOA requires.
We plan the excavation and below-grade work around Coral Springs’s high water table from day one. That means dewatering trenches and footer pits where standing groundwater appears, coordinating any below-grade sewer or plumbing tie-ins with the South Florida Water Management District drainage easement, and keeping the structure weather-tight before the June-November hurricane window arrives. Permitting timing matters here too. A permit delay that pushes framing into late August is a real risk. We schedule around it. Call (877) 610-1318 for a construction timeline tied to the current permitting calendar.
Because the HOA architectural review committee approves aesthetics, not scope, price, or field conditions. If your ADU slab hits groundwater at three feet and the dewatering scope grows, or the county inspector requires a structural tie-in upgrade to the existing CBS wall, that’s a change to the job you agreed to. In Coral Springs, where the water table and pre-code structural surprises are real, every scope change becomes a written change order before work proceeds. You sign it, or we don’t do it. That’s how you avoid the surprise invoice at the end. Get your free estimate at (877) 610-1318.
