Fast, Reliable Home Additions & ADU Across North Andrews Gardens
A room addition or detached ADU in North Andrews Gardens typically runs $45,000 to $130,000, and a new detached ADU starts closer to $100,000 once county permitting, site prep, and utilities are scoped. Those numbers reflect what we see on the 1950s and 1960s CBS homes that define this unincorporated Broward County neighborhood, where every permit goes through the county rather than a city hall. We’re Barrett & Sons Construction, owner-operated since 1998, and we’ve scoped enough additions near the Oakland Park boundary to know that the wrong permit type on the wrong parcel means starting over. Call (877) 610-1318 and we’ll walk your lot before we quote it.
Why Barrett & Sons Construction Is North Andrews Gardens’s Preferred Home Additions & ADU Company
Tom Barrett and his sons run the crews that build in North Andrews Gardens. You won’t get a franchise dispatcher sending strangers; you’ll get the same faces from the first estimate to the final inspection. Our customers in the 33334 ZIP have told us the same thing for 29 years: they want a name they can verify and a contractor who answers his own phone.
We know the county permitting desk in Broward better than most because we’ve been through it hundreds of times. When a homeowner near Andrews Avenue calls about a garage conversion ADU, we can tell them before we even look at the parcel whether the county will require wind-load upgrades on the original CBS walls. That’s the kind of thing you learn only by building here. We publish Tom’s name, address, and license number, and every scope, allowance, and price change arrives as a written change order before work moves. No surprises at the end.
Our Home Additions & ADU Services in North Andrews Gardens
New Detached ADU
A new detached ADU in North Andrews Gardens starts around $100,000 and often climbs to $220,000 depending on square footage, foundation engineering, and utility runs. Because this is unincorporated Broward, your ADU permit goes through the county, and if your parcel is near the Oakland Park line, we verify jurisdiction on the Broward County Property Appraiser map before we pull anything. We also check septic and well setbacks early, because those distances can shrink your buildable footprint and change the price before you’ve spent a dime.
ADU Site Prep & Utilities
Site prep in North Andrews Gardens is not just clearing a patch of lawn. The sandy-limestone substrate and shallow water table mean footer excavation often needs dewatering, especially from June through September. Utility runs across a larger lot can add $9,000 to $22,000 to the project, and if you’re on septic and well rather than municipal sewer and water, the permitting path runs through the Florida Department of Health in addition to Broward County. We scope these line items in writing before quoting so the allowance is real, not a guess.
Garage Conversion ADU
Garage conversions in North Andrews Gardens run $30,000 to $80,000, with the spread driven by what’s hiding in the original structure. Most garages here were built as part of 1955-to-1975 CBS homes, and the moment you convert a garage to living space, Broward County requires the walls to meet post-Andrew high-velocity hurricane zone standards. That can mean structural reinforcement before insulation ever goes in. We scope that compliance cost up front, because the worst time to learn about it is after the drywall is ordered.
Junior ADU & Interior Conversion
A junior ADU carved out of an existing attached room or converted interior space is often the fastest path to added square footage, and it avoids some of the setback headaches of a detached build. Interior conversions still trigger county inspections for electrical, plumbing, and egress, but they don’t disturb the roofline or require the same slab work as a detached addition. For a 1960s ranch near Andrews Avenue, this can be the difference between a four-month build and a six-week one.

Trusted Brands We Service in North Andrews Gardens
We build with materials you can look up, not mystery brands off a van. On paver driveways and patio work tied to your addition, we regularly install Techo-Bloc and Cambridge Pavers, and we use Quikrete and Oldcastle for foundational concrete and block work. Because our crew members carry the Barrett & Sons name and answer to Tom, they treat your property the way they’d treat a neighbor’s. We don’t stock local parts for North Andrews Gardens customers because we’re a supply house; we order direct for your job and stage materials according to county inspection dates so nothing sits in the rain.
Common Home Additions & ADU Problems We See in North Andrews Gardens Homes
- Wrong jurisdiction on the permit. Lots near the North Andrews Gardens/Oakland Park boundary can sit in different jurisdictions on the same street. We pull a county permit for a parcel that’s actually city-incorporated and you’re back to square one, paying fees twice.
- Underestimated wind-load compliance. Original 1950s-1970s CBS walls predate Broward’s post-Andrew high-velocity hurricane zone codes. Once a permitted addition crosses the threshold value, those walls need structural upgrades, and that cost can blow an allowance before drywall goes up.
- Rainy-season excavation problems. Digging footers in June through September without a dewatering plan leads to slab settlement and moisture intrusion. The water table in eastern Broward is shallow, and afternoon thunderstorms are near-daily.
- Septic and well setback surprises. A lot that looks big can shrink fast when health-department setbacks are measured. We find the buildable envelope before you sign, not after the survey comes back.

FAQs - Home Additions & ADU in North Andrews Gardens
How do I know if my North Andrews Gardens lot needs a county or city permit for an ADU?
Check your parcel on the Broward County Property Appraiser map, because North Andrews Gardens is unincorporated and falls under the Broward County Building Division, but lots on the same street can sit in city-incorporated Oakland Park or Fort Lauderdale. If you pull a county permit on a city parcel, the process stops and you start over with the city. We verify this before we quote, and the permit inspector works for you, not for us. Call (877) 610-1318 if you’d like help confirming your parcel.
Why does a room addition on my 1960s CBS home require extra wind-load engineering?
Because your original concrete block and stucco walls were built before Broward County adopted post-Hurricane Andrew high-velocity hurricane zone requirements. Once a permitted renovation exceeds threshold values, the county requires the existing structure to meet current wind-load and roof-deck compliance standards. That engineering cost is real, and it should be in your allowance before the first nail moves, not sprung on you at rough-in. We write it into the scope so the allowance on paper matches the inspection in the field.
Can I connect a detached ADU to my existing septic system in North Andrews Gardens?
Sometimes, but not automatically. A detached ADU adds bedroom capacity, and the Florida Department of Health must confirm your existing septic system can handle the additional flow before the county will sign off. If the system is undersized, you’ll need an upgrade, and that line item belongs in the written change order before excavation starts. We coordinate the health department review as part of our ADU Site Prep & Utilities scope.
How does the rainy season affect scheduling for my garage conversion ADU?
June through September in North Andrews Gardens means near-daily afternoon thunderstorms, and that compresses exterior work to morning hours. For a garage conversion, the main risk is slab work and any exterior wall penetrations, which need dry windows to cure properly. We sequence the noisy or wet work around the forecast, and we plan inspections so the final sign-off doesn’t slip into storm delays. Call (877) 610-1318 for a schedule that accounts for the rain, not one that pretends it won’t happen.
What’s the typical permit timeline for a home addition in unincorporated Broward?
Plan on three to six weeks for plan review through the Broward County Building Division, depending on current volume and whether your project triggers wind-load review, health department septic review, or zoning variance requests. North Andrews Gardens parcels near the Oakland Park boundary can take longer if jurisdiction verification is required. We pull permits on every eligible job and we don’t tell you permits are optional, because the county inspector works for you, not for us. For an exact timeline on your project, call (877) 610-1318 and we’ll review your parcel.
Building on Your Lot, Not Around It
In unincorporated North Andrews Gardens, every home addition or ADU permit goes through the Broward County Building Division, not a city hall. That means your project’s timeline, fee schedule, and code-compliance path depend on a county process that doesn’t care how fast you want to move. The same street can have different jurisdictions, and pulling the wrong permit type means restarting from scratch. We’ve watched too many homeowners eat that cost because a contractor guessed instead of checking the county property map.
On a 1958 CBS home near the Oakland Park boundary, we scoped a detached ADU with a new well setback variance and a slab-on-grade foundation engineered for the sandy-limestone water table. Our crew coordinated county inspections for rough-in and load-bearing beam placement, then sequenced exterior work around the rainy season so the final inspection sign-off landed before the afternoon storms. That’s what building in North Andrews Gardens actually looks like, and it’s why we price the lot before we price the lumber.
The big cost drivers on an open lot are septic and well setbacks, material haul distance, and grading. If your property sits far from the road or on low ground, expect fill, drainage, and possibly a longer utility trench, all of which add line items to the scope. We scope those before we quote, in writing, so the number you sign is the number the job costs. An allowance that isn’t on paper is a surprise waiting for a date.
Call (877) 610-1318 today to schedule your free estimate for a home addition or ADU in North Andrews Gardens. Tom or one of his sons will meet you at your property, walk the lot, check the parcel map, and put every scope and allowance in writing. One call brings the same faces back for the build, and the 90-Day Done Right Promise is written on the contract, not buried in fine print.
