Junior ADU & Interior Conversion in North Andrews Gardens - What It Costs and How Long It Takes
Junior ADU & Interior Conversion in North Andrews Gardens typically runs $45,000-$130,000 and takes 8-14 weeks from permit approval to final inspection, depending on whether you’re reconfiguring an existing garage, converting a large portion of your home’s interior, or adding a small attached unit with its own kitchenette and bath. Because North Andrews Gardens sits in unincorporated Broward County, every permit routes through the county building department, not a city office, which adds a specific timeline layer you won’t encounter in neighboring Oakland Park or Fort Lauderdale. Call (844) 665-0162 and we’ll walk you through what your particular floor plan allows.
How We Approach Junior ADU & Interior Conversion Start to Finish
We’ve learned that homeowners in North Andrews Gardens want to know what happens on their property week by week, not just a glossy before-and-after. Here’s the actual sequence we follow.
Stage 1: Feasibility and as-built documentation (1-2 weeks). We measure your existing layout, photograph structural elements, and verify what the original 1950s-1970s CBS construction can support. You’ll decide right here whether the junior ADU stays within the existing footprint or bumps out slightly. We also pull any prior permits on file with Broward County, since unpermitted work from decades past surfaces constantly in this neighborhood and affects what we can legally tie into.
Stage 2: Design and permit submission (3-6 weeks). Our team drafts plans showing the new bedroom, living area, kitchenette, and full or three-quarter bath layout. Because North Andrews Gardens is unincorporated, we submit directly to Broward County Building and Code Compliance, not a municipal office. County inspectors here enforce post-Hurricane Andrew wind-mitigation standards, so if your home still has original windows or an older roof, we’ll flag whether those need upgrading to satisfy the same permit. You choose your material tier during this stage - flooring, cabinetry, fixtures - because those selections affect the electrical and plumbing load calculations we submit.
Stage 3: Structural prep and rough trades (2-4 weeks). Demolition is usually limited: we remove non-load-bearing partitions, open kitchenette plumbing walls, and run new electrical circuits from your panel. If your service panel is original Federal Pacific or Zinsco (common in this era of North Andrews Gardens housing), we may need to upgrade it to handle the additional dwelling unit load. You’ll see county inspectors at this point for rough electrical, plumbing, and framing.
Stage 4: Finish installation (2-3 weeks). Insulation, drywall, flooring, cabinetry, countertops, and fixture set happen here. We coordinate our own crews for carpentry and finishes, which is where working with a Home Additions & ADU single-source contractor matters - no gaps between the plumber and the tile setter, no finger-pointing if a cabinet doesn’t fit the rough plumbing.
Stage 5: Final inspection and certificate of completion (1 week). Broward County returns for final walkthrough. We address any punch items immediately, then hand you documentation for your records and any insurance or rental applications. The whole project, from our first site visit to county sign-off, usually spans 4-5 months including permit wait times.
The Material and Layout Choices That Shape Your Junior ADU
Every junior ADU & interior conversion in North Andrews Gardens forces real decisions. These aren’t cosmetic preferences - they change how the space functions and what you’ll spend.
- Separate exterior entrance or interior access only. A private entrance adds $3,500-$8,000 for door, landing, and possible stoop or ramp, but it’s what makes a junior ADU legally rentable in most scenarios. Interior-only access works for family use or caregiver quarters and keeps the budget tighter.
- Kitchenette scope: wet bar vs. full cooking. A microwave, mini-fridge, and sink runs roughly $4,000-$7,000 in plumbing and electrical. Adding a 24-inch range and full ventilation bumps that to $8,000-$14,000 and may require upgrading your home’s gas or electrical service. For rental income, the full cooking setup pays back faster.
- Bath configuration: three-quarter vs. full. A shower-stall bath fits in 30 square feet and costs $5,000-$9,000. A tub-shower combo needs 40+ square feet and runs $7,000-$12,000. In the compact footprints we typically convert in North Andrews Gardens, the three-quarter bath usually wins unless you’re targeting families as renters.
- Flooring: LVP, tile, or engineered hardwood. Luxury vinyl plank at $4-$7 per square foot installed handles moisture and tenant wear without fuss. Porcelain tile at $7-$12 per square foot lasts longer but feels colder and raises your slab prep costs if the existing concrete isn’t level. Engineered hardwood looks sharp but isn’t our first recommendation for rental units in humid South Florida.
- Countertops and cabinetry grade. Stock cabinetry with laminate counters keeps kitchenette costs near $3,500. Semi-custom cabinets with Silestone or Caesarstone surfaces push toward $8,000-$11,000 but resist the staining and humidity issues we see in ground-level conversions near the Broward coastal plain. We stock both paths so you choose, not us.
What Junior ADU & Interior Conversion Costs in North Andrews Gardens, FL
Junior ADU & interior conversion in North Andrews Gardens falls in the $45,000-$130,000 range, with most projects we’ve completed in this neighborhood landing between $65,000 and $95,000.
| Cost Driver | Low-End Impact | High-End Impact |
|---|---|---|
| Size (400-800 sq ft typical) | $45,000-$65,000 | $90,000-$130,000 |
| Existing condition (original 1960s-70s finishes intact) | Less demo, simpler rough-in | Abatement, structural repair, panel upgrades |
| Plumbing/electrical relocation | Kitchenette and bath stack near existing lines | Cross-house runs, new sewer lateral, service upgrade |
| Material grade | Stock cabinets, LVP, fiberglass shower | Semi-custom, stone counters, tile, glass enclosure |
| Permit scope and county requirements | Interior conversion only | Triggered wind-mitigation upgrades, impact windows, roof ties |
What moves you to the high end? Original aluminum wiring that needs replacement. A Federal Pacific panel that won’t carry the additional load. Discovering a previous owner’s unpermitted room addition that Broward County now wants brought to current code. What keeps you on the lower end? Working within the existing footprint, keeping the kitchenette modest, and timing the project alongside other work like Kitchen Design & Layout in North Andrews Gardens or Small & Partial Kitchen Remodels in North Andrews Gardens so we bundle mobilization and permit fees.
A written estimate from us includes demolition, rough and finish carpentry, plumbing and electrical rough-in and trim, insulation, drywall, flooring, cabinetry, countertops, fixtures, paint, and final cleanup. It does not include permit fees (typically $800-$2,400 in Broward County), designer or architect fees if you hire separately, or any required structural or MEP engineering stamps.
Why North Andrews Gardens Homes Make This Job Different
North Andrews Gardens isn’t like the incorporated cities around it, and that changes how we build here.
Because the community is unincorporated Broward County, all construction permits and inspections run through the Broward County Building and Code Compliance Division - a workflow distinctly different from neighboring incorporated cities like Oakland Park or Fort Lauderdale. Contractors here must navigate county-level permitting timelines and county inspectors, and older homes often need retroactive wind-mitigation upgrades to satisfy Broward County’s post-Hurricane Andrew code revisions that have been phased in since 2014. What this means for your junior ADU & interior conversion: the moment we pull a permit, county inspectors will assess your existing structure for compliance with current HVHZ standards. If your home still has original jalousie windows, a non-hip roof, or pre-1994 garage door openings, those become part of the same project whether you planned for them or not.
The housing stock itself shapes our approach. The neighborhood is dominated by modest, single-story CBS homes built primarily from the late 1950s through the 1970s, many with flat or low-slope roofs that predate current South Florida hurricane-resistance standards. These slabs sit on the flat, low-elevation coastal plain where the water table is often just a few feet below grade. Any ground-level conversion needs moisture barriers and careful drainage planning - we’ve seen too many junior ADUs in this area develop efflorescence or mold because a previous contractor skipped the vapor barrier under new flooring.
And then there’s the surprise factor. Because the community is unincorporated, many long-time homeowners don’t realize unpermitted additions or garage conversions from the 1970s-80s trigger full county code compliance the moment a licensed contractor pulls a new permit. We find these buried in permit histories regularly. It’s better to discover them in our feasibility stage than at rough inspection. North Andrews Gardens rewards contractors who do their homework upfront.

Frequently Asked - Junior ADU & Interior Conversion in North Andrews Gardens
From permit approval to final county inspection, expect 8-14 weeks of construction. Add 3-6 weeks for Broward County permit review, and 1-2 weeks for our initial feasibility and design work. Total timeline is typically 4-5 months. Call (844) 665-0162 and we can give you a tighter estimate once we see your existing layout.
Yes, absolutely. Because North Andrews Gardens is unincorporated Broward County, all permits route through the Broward County Building and Code Compliance Division, not a city office. Any work involving new plumbing, electrical, or a separate dwelling unit requires full permitting. Unpermitted junior ADUs also jeopardize your insurance coverage and any future sale. We handle the entire permit submission as part of our process.
Sometimes, but rarely in the 1950s-1970s homes common here. Original layouts in North Andrews Gardens usually cluster plumbing on one side of the house. If your target conversion space is on the opposite side, we need to run new supply and waste lines - typically $4,000-$9,000 additional. Keeping the kitchenette and bath near existing stacks is the single biggest budget saver we can recommend.
Usually yes. A junior ADU & interior conversion in North Andrews Gardens starts around $45,000, while detached ADU construction in this market runs $90,000-$220,000 because you’re building new foundation, walls, and roof from scratch. The trade-off is privacy and rental income potential - a detached unit commands higher rent and doesn’t share your HVAC system. For many homeowners here, the junior ADU is the practical first step, especially if you’re converting underused space like a garage or large den.
We warranty our workmanship for one year from final completion. Manufacturer warranties apply to specific products you select - cabinetry, fixtures, flooring, windows - and vary by brand. We document every warranty and registration for you at project closeout. For a project this scale, we also do a 30-day and 11-month walkthrough to catch anything that settles or shifts after completion. Call (844) 665-0162 to discuss what’s covered in detail for your specific material selections.
