What Does Junior ADU & Interior Conversion Cost and Take in West Park?
Junior ADU & Interior Conversion in West Park typically runs $45,000-$130,000 and takes 10-16 weeks from permit approval to final inspection. Most West Park homeowners are converting an existing bedroom wing, attached garage, or underutilized first-floor space into a self-contained unit with its own kitchenette, full or three-quarter bath, and separate entrance. Call (844) 665-0162 and we’ll walk your specific layout and give you a written estimate with line-item pricing.
How We Handle Junior ADU & Interior Conversion from First Walkthrough to Final Walkthrough
We’ve learned that West Park projects go smoother when homeowners know exactly when they’re making decisions and when we’re moving dirt. Here’s how we sequence a typical junior ADU & Interior Conversion.
Stage 1: Existing Conditions & Code Review (Week 1)
We start by documenting what’s actually there, not what the county records say. In West Park, we pull permits through the city’s building department and cross-check against Broward County’s legacy files. We’re looking for unpermitted prior work, the amp rating on your electrical panel, and whether your slab shows moisture intrusion. You’ll decide at this stage whether to proceed with a full kitchenette or a wet-bar-plus-microwave setup, which affects both plumbing scope and permit classification. We deliver a written estimate with three material tiers within five business days.
Stage 2: Design & Permit Submission (Weeks 2-6)
Our draftsman produces plans showing the new partition walls, egress window or door location, kitchenette layout, and mechanical routing. For West Park’s 1950s-1970s CBS homes, we often need structural calcs when we’re removing sections of load-bearing block wall to create the separate entrance. You’ll choose your cabinet line, countertop material, flooring, and fixture package during this window. We submit to West Park’s building department and handle any plan corrections. Permit turnaround here typically runs 3-4 weeks, though it stretches longer if legacy unpermitted work surfaces and requires remediation drawings.
Stage 3: Rough Construction & MEP Rough-In (Weeks 7-10)
Demo happens first, usually two to three days. We frame new interior partitions, rough in the electrical sub-panel or feeder upgrade, run PEX or copper for the kitchenette and bath, and set the plumbing vent stack. If we’re adding a separate HVAC mini-split, we coordinate the line-set routing through the existing structure. Your inspections at this stage are framing, electrical rough, plumbing rough, and mechanical rough. We don’t cover walls until every rough pass is signed off.
Stage 4: Insulation, Drywall, Finishes & Fixture Set (Weeks 11-14)
We insulate to current Florida Energy Code, hang and finish drywall, then move through flooring, cabinetry, countertops, tile, and trim. For West Park’s flat-roof stock, we’re especially careful with ceiling plane continuity; any recessed lighting or vent penetration gets sealed against attic moisture migration. You’ll do a midpoint walkthrough when cabinets are hung but before countertops are templated, which is your last chance to adjust hardware or backsplash scope without change-order pricing.
Stage 5: Final Inspections, Punch List & Certificate of Occupancy (Weeks 15-16)
Final electrical, plumbing, mechanical, and building inspections happen in sequence. We address the punch list items you flag, then turn over your certificate of occupancy and as-built drawings. If your junior ADU & Interior Conversion is part of a full Home Additions & ADU in West Park project, we coordinate this handoff with the next phase so you’re not living in construction indefinitely.
The Material and Layout Choices That Actually Move Your Number
Every junior ADU & Interior Conversion forces real trade-offs. We don’t pretend there’s one right answer.
- Kitchenette scope: A two-burner cooktop, under-counter fridge, and single-bowl sink runs far less than a full four-burner range, dishwasher, and vented hood. For West Park’s compact CBS layouts, the smaller package often fits better and keeps you under the square-footage threshold that triggers additional parking requirements.
- Cabinetry grade: KraftMaid’s semi-custom lines give you finished sides and soft-close hardware at a mid-tier price. Wellborn’s full-custom program costs more but handles odd ceiling heights and bulkhead conditions common in postwar Florida block homes. Stock big-box cabinets save money upfront; we’ve seen them fail faster in South Florida’s humidity.
- Countertop surface: Cambria quartz carries a lifetime warranty and needs no sealing, which matters if you’re renting the unit. Laminate costs roughly half but shows wear within five years in a rental scenario. Butcher block looks warm and costs less than stone, though it demands regular maintenance in humid conditions.
- Flooring: Luxury vinyl plank handles moisture and installs fast over existing slab. Tile is bulletproof but colder underfoot and raises your floor height, which can create threshold issues with existing doors. Engineered hardwood is possible with proper moisture mitigation; we don’t recommend solid wood directly on West Park’s slab-on-grade construction.
- Separate entrance location: Converting an existing window to an egress door in a block wall is straightforward. Cutting a new opening through load-bearing structure, or pouring a small stoop and step assembly, adds concrete and rebar work that can push your timeline by a week and your budget by several thousand.
What Junior ADU & Interior Conversion Costs in West Park, FL
In the Fort Lauderdale market, which covers West Park, junior ADU & Interior Conversion projects range from $45,000 to $130,000. Most West Park jobs we price land between $55,000 and $85,000.
Five variables push you toward the high or low end:
- Existing condition of the space: A finished bedroom with good electrical and no moisture issues starts cheaper than a garage with a cracked slab, no HVAC, and a 60-amp panel that needs upgrading.
- Plumbing relocation distance: If your target space backs up to an existing bathroom or kitchen, tying into existing drain lines is simple. Running new waste lines across the house to reach the sewer lateral adds significant labor and material.
- Structural modifications: Removing sections of CBS wall for a separate entrance, or adding a header for a wider opening, requires structural engineering and permit amendments. Non-structural partition walls don’t.
- Material and fixture selections: The difference between entry-level and mid-grade finishes typically spans $8,000-$15,000 on a junior ADU this size. Going from mid-grade to premium with stone, custom cabinetry, and name-brand fixtures can add another $15,000-$25,000.
- Permit and remediation scope: West Park’s legacy of unpermitted county-era work means we sometimes discover conditions that must be brought current before new work proceeds. This is the most unpredictable cost driver, which is why we front-load our code review.
Our written estimates include demolition, framing, MEP rough-in and finish, insulation, drywall, flooring, cabinetry, countertops, fixtures, trim, paint, and permit fees. They don’t include furniture, window treatments, or landscaping repair outside the immediate work area. If your project needs electrical service upgrade or sewer line extension, we price those separately so you see exactly where your money goes.
Why West Park’s History Changes How We Approach This Job
West Park only became its own city in 2005. Before that, everything here was unincorporated Broward County, and the county’s permitting enforcement was uneven at best. When we open walls on a junior ADU & Interior Conversion in the 33023 zip, we routinely find garage conversions, rear additions, or re-roofs that were done without permits or never received final inspection. That matters because West Park’s building department now requires all existing work in the footprint to meet current Florida Building Code before they’ll sign off on your new certificate of occupancy.
The housing stock itself is almost entirely 1950s-1970s concrete block and stucco, built during Broward’s postwar suburban expansion. These are compact, low-slung homes with flat or low-slope roofs and original slab-on-grade foundations. The soil doesn’t drain well, and during rainy season the water table sits close to the surface. Any plumbing rough-in or foundation modification needs moisture mitigation we wouldn’t specify in better-draining terrain. Electrical panels are often 60-100 amp, which won’t support a second kitchen and bath without an upgrade. And roof systems are frequently past service life, meaning we sometimes coordinate reroofing with your interior conversion so the new work isn’t compromised by leaks six months later.
We’ve also learned to ask early about HOA restrictions. Several West Park neighborhoods carry covenants written during the county era that restrict secondary dwellings or exterior modifications. We review those documents before permit submission so you’re not surprised by a violation letter after construction starts.

Frequently Asked - Junior ADU & Interior Conversion in West Park
From permit approval to final inspection, expect 10-16 weeks. Permit submission to approval typically adds another 3-6 weeks in West Park, longer if legacy unpermitted work requires remediation drawings. Call (844) 665-0162 and we’ll give you a realistic timeline for your specific property after our initial walkthrough.
Yes. West Park’s building department requires permits for any conversion that adds kitchen or bath facilities, creates a separate dwelling unit, or modifies structural, electrical, or plumbing systems. Because of the city’s 2005 incorporation, your permit application may trigger review of prior unpermitted work on the property. We handle that discovery process as part of our standard pre-construction review.
Sometimes. If your target space already has a bathroom and backs up to a kitchen wall, you may only need to add a kitchenette and separate entrance. That keeps you at the lower end of the price range. If you’re converting a bedroom or garage with no nearby plumbing, you’ll need new waste and supply lines run, which is when costs climb. We’ll show you both scenarios during our walkthrough.
A junior ADU is created within the existing footprint of your primary residence, typically 500 square feet or less, and must have interior access to the main house as well as its own exterior door. A full ADU is a separate structure or entirely independent unit. Junior ADUs avoid some of the parking and setback requirements that burden detached units in West Park, and they usually cost 40-60% less than new construction. Our Home Additions & ADU crew can walk you through which path fits your goals.
We warranty our workmanship for one year from certificate of occupancy. Manufacturer warranties apply to specific products: KraftMaid and Wellborn cabinetry carry limited lifetime warranties on defects, Cambria backs its quartz with a lifetime residential warranty. We pass all manufacturer documentation to you at closing so you have direct recourse if any product fails.
Many homeowners do. If you’re already living through construction, coordinating a Kitchen Design & Layout in West Park or Small & Partial Kitchen Remodels in West Park during the same window reduces total disruption and can save on mobilization costs. We sequence the work so you’re not without a functional kitchen for the full duration.
