AfterFast, Reliable Home Additions & ADU Across Davie
A typical home addition or ADU in Davie runs $45,000-$130,000 for attached room additions and $90,000-$220,000 for detached ADU construction, with most projects permitted and underway within 8-12 weeks of the signed contract. We’re the Home Additions & ADU crew that Davie homeowners call when they’re opening up a 1970s CBS house and need to know what’s actually behind the stucco before anyone quotes a finished price. Call (754) 254-7676 to schedule your free estimate - we’ll walk the property, check the existing conditions, and deliver a written scope and flat price before any work starts.
Why Rowan Construction Group Fort Lauderdale Is Davie’s Preferred Home Additions & ADU Company
We’ve delivered 4,000-plus projects since 2007, from Bathroom Remodeling in Davie to full home additions, every one with a written price before work started and a documented photo record when the crew left. Davie homeowners find us because they’re reading the three-star reviews and want to see what a contractor actually documents, not what they promise.
Our crews serve Davie from our Miami-area dispatch office, with background-checked, uniformed technicians who arrive with a photo log running from the first site visit. The 365-Day Done Right Promise is printed on every page of our contract, backed by a terms page you can screenshot and compare - not an asterisk.
What separates us in Davie specifically: we know the Town’s equestrian overlay regulations, the SFWMD canal setback rules, and the difference between Broward County residential code and Davie’s A-1 agricultural setbacks. A contractor who misses that distinction can have a permitted project stall at inspection. We catch it in pre-construction, priced into the original scope.
Our Home Additions & ADU Services in Davie
ADU Design & Permitting
ADU permitting in Davie starts with a zoning verification that most contractors skip. Is your lot in an A-1 equestrian district? Are there canal setback lines from the South Florida Water Management District running across the rear? We’ve seen permits stall for six weeks because a designer drew to Broward County residential setbacks when Davie’s agricultural accessory-structure rules applied. Our design phase includes a Town of Davie zoning letter, elevation certificate review if you’re in a FEMA Special Flood Hazard Area, and a written permit timeline before you sign. ADU construction in Davie typically runs $90,000-$220,000 depending on size, utility tie-ins, and whether we need stem-wall fill to meet Base Flood Elevation.
Garage Conversion ADU
Garage conversions are popular in Davie’s older subdivisions off Nova Drive and Davie Road, where 1970s and 1980s CBS homes have attached two-car garages sitting on slabs that may or may not meet current flood elevation. The first thing we check: is the existing slab above Base Flood Elevation? If not, the conversion triggers the same elevation certificate and stem-wall requirements as new construction. We price that in the original quote, not as a surprise after demo. Garage conversion ADUs in Davie run $30,000-$80,000, with the lower end for spaces that already have adequate slab elevation and the higher end for fill-raising, new electrical service, and separate meter installation.
New Detached ADU
A detached ADU on a Davie equestrian lot is where the Town’s unique zoning gets serious. Residential setbacks, agricultural accessory-structure setbacks, and canal-proximity lines can all apply simultaneously. Our crew opened up a 1978 CBS house off Griffin Road near the Davie rodeo grounds for a 500-square-foot primary-suite addition, and once the stucco came off we found aluminum branch wiring, termite-tunneled framing at the rim joist, and a subfloor that had been wicking canal-side groundwater for years. We paused the scope of work, priced the wire replacement, sistered framing, and new subfloor as a written change order, and got inspection sign-off before the drywall went back up. That’s the discipline that keeps projects within a few percent of the agreed price. New detached ADUs in Davie start around $90,000 and run to $220,000 for larger structures with full kitchens and utility separations.
Junior ADU & Interior Conversion
Junior ADUs - converted interior spaces with a small kitchenette and separate entrance - work well in Davie’s larger CBS homes where a wing of the house can be sectioned off without touching the envelope. The critical check here is the existing electrical panel: many pre-1992 Davie homes have 100-amp service that won’t carry an additional kitchen circuit, HVAC mini-split, and separate water heater. We open the panel and verify capacity during the estimate visit, then price any service upgrade in the original written quote. Junior ADU conversions in Davie typically fall in the $30,000-$80,000 range depending on whether we’re working within existing systems or upgrading them.
Room Additions
Room additions on Davie’s older CBS homes - the 1,400-square-foot ranch-style houses common in neighborhoods near Shenandoah - almost always trigger code upgrades once walls are open. The Florida Building Code requires current wind standards for any structural modification, which means the connection between existing roof framing and new addition framing gets engineered, not guessed. We inspect the existing roof structure before we quote, price the tie-in method in writing, and document with photos at each inspection milestone. A typical room addition in Davie runs $45,000-$130,000.
Second Story Additions
Second story additions in Davie are less common than in denser Broward cities because many Davie lots are large enough to build out rather than up. Where they do make sense - typically on smaller infill lots near downtown Davie - the existing foundation and wall capacity must be verified for the additional load. We bring a structural engineer to the estimate visit, price the engineering report in the original quote, and never proceed on a change until the change order is signed.

Common Home Additions & ADU Problems We See in Davie Homes
- Aluminum branch wiring behind intact stucco. Pre-1980 Davie CBS homes often have aluminum wiring that was grandfathered until walls are opened. Once a permit triggers electrical inspection, the inspector will flag it. We catch this with a pre-demo inspection and price replacement as an allowance in the original contract, not a mid-build surprise.
- Canal-side groundwater wicking into slab and subfloor. Davie’s low-lying terrain and SFWMD drainage canals mean many homes sit with chronic moisture at the slab edge. We check for it during the estimate, specify vapor barrier and drainage improvements in the written scope if needed, and document conditions with photos before any framing starts.
- Elevation certificate gaps stalling permits. Substantial portions of Davie are in FEMA Special Flood Hazard Areas. New construction and significant remodels require elevation certificates proving the finished floor meets Base Flood Elevation. We order the certificate during design, price any fill-raising or stem-wall work upfront, and never start demo until the permit is approved.
- A-1 agricultural setback violations on equestrian lots. A detached ADU or barn-adjacent addition designed to Broward County residential setbacks can get flagged when Davie’s A-1 rules require greater distance from property lines and canals. We verify overlay rules with the Town before design finalization, so the first inspection is a pass, not a rewrite.

We handle this with an inspection-first estimate, written allowances for likely discoveries, and signed change orders for anything outside the original scope. No work proceeds on a change until the change order is signed - that’s Clause 1 of the Haven Standard, and it’s why our projects finish within a few percent of the number you agreed to.

FAQs - Home Additions & ADU in Davie
Davie’s equestrian overlay, canal-proximity rules, and flood zone requirements add compliance steps that don’t exist in most Coral Springs residential zones. A Davie project may need elevation certificates, agricultural setback verification, and SFWMD drainage review - each priced into the original quote, but each adding time and documentation that simpler zoning doesn’t require. Call (754) 254-7676 for an exact quote on your specific lot - estimates are free.
The permit triggers current Florida Building Code requirements for any exposed structural, electrical, or plumbing work, which in a 1970s Davie CBS home typically means aluminum wiring replacement, wind-rated roof tie-downs, and possibly slab moisture remediation if groundwater wicking is found. We catch these conditions with a pre-demo inspection and write allowances into the original contract, so the permit inspection is a confirmation, not a surprise. Call (754) 254-7676 to schedule an inspection-first estimate.
Yes, but the siting must comply with three overlapping setback rules: Town of Davie residential setbacks, A-1 agricultural accessory-structure setbacks, and SFWMD canal-proximity requirements. We verify all three with the Town’s zoning department before design finalization, price any fill-raising for Base Flood Elevation in the original quote, and document the approved siting plan in your project file. Call (754) 254-7676 to review your specific lot configuration.
If your existing garage slab is below Base Flood Elevation and your property is in a FEMA Special Flood Hazard Area, the conversion will require an elevation certificate and likely stem-wall fill-raising to meet current standards. We check this during the estimate visit, order the certificate during design, and price the work in writing before you sign. No demo starts until the permit is approved. Call (754) 254-7676 for a free assessment of your garage slab elevation.
We inspect before we quote, write allowances for likely discoveries based on what we find, and require a signed change order for any work outside the original scope. The field vignette: our crew opened up a 1978 CBS house off Griffin Road near the Davie rodeo grounds for a 500-square-foot primary-suite addition, and once the stucco came off we found aluminum branch wiring, termite-tunneled framing at the rim joist, and a subfloor that had been wicking canal-side groundwater for years. We paused the scope of work, priced the wire replacement, sistered framing, and new subfloor as a written change order, and got inspection sign-off before the drywall went back up.
