Junior ADU & Interior Conversion in Pompano Beach Highlands - Scope, Timeline & Cost
A Junior ADU & Interior Conversion in Pompano Beach Highlands transforms an existing bedroom, attached garage section, or underutilized interior space into a self-contained living unit with its own kitchenette, full bath, and separate entrance, typically running $45,000-$130,000 and taking 10-16 weeks from permit approval to final inspection. Because most Pompano Beach Highlands homes are 1960s-1970s CBS construction, these jobs almost always require simultaneous wind-mitigation and electrical upgrades that a newer home wouldn’t need. Call (844) 665-0162 and we’ll walk through your specific floor plan and what the county will require.
How We Approach a Junior ADU & Interior Conversion Start to Finish
We’ve done enough of these in older Broward County homes to know where the surprises hide. Here’s how we sequence a typical Junior ADU & Interior Conversion in Pompano Beach Highlands, and what you’ll need to decide at each point.
Stage 1: Existing Conditions & Code Review (Week 1)
We pull the original permit history, inspect the electrical panel capacity, and verify whether your parcel falls under Broward County or City of Pompano Beach jurisdiction - this dual-pathway permitting reality in the Highlands changes our submittal strategy and timeline. You’ll decide whether to proceed with a full 200-amp service upgrade now or phase it later, and whether to include impact-rated door and window replacements as part of the same permit package. Most homeowners choose to bundle; it saves roughly 3-4 weeks of separate inspection scheduling.
Stage 2: Design & Material Selection (Weeks 2-4)
This is where you choose between a wet bath with integrated shower pan versus a full tiled shower, compact appliance packages (24-inch ranges and drawer dishwashers versus standard sizes), and whether the kitchenette runs on electric or gas if your home has existing LP service. We spec KraftMaid or Wellborn cabinet lines for the kitchenette depending on your finish preference and budget tier. You’ll also select flooring - LVP holds up better to the humidity we see in these slab-on-grade CBS homes than engineered hardwood. We finalize drawings and submit for permit during this window.
Stage 3: Structural & MEP Rough-In (Weeks 5-9)
Demolition is limited since we’re working within existing envelope, but we often need to sister ceiling joists for added load from insulation and mechanicals, and we always run new dedicated circuits for the kitchenette and bath. If your home still has original aluminum wiring, this stage includes full replacement to copper per current code. The high water table and flat terrain in Pompano Beach Highlands means we pay particular attention to slab moisture barriers before sealing new flooring. You’ll do a mid-rough walkthrough to confirm fixture locations before we close walls.
Stage 4: Finish Installation (Weeks 10-14)
Cabinets, countertops, tile, flooring, trim, and paint. For countertops, we typically spec quartz or solid surface in these compact kitchens - Cambria runs at the higher end of the range but performs well against the salt-laden air that corrodes lesser materials faster here, roughly a mile and a half from the Atlantic. We install the separate exterior entrance, which in Pompano Beach Highlands must be impact-rated if it’s on any face with wind exposure. Final plumbing and electrical connections happen in the last week of this stage.
Stage 5: Inspections & Closeout (Weeks 15-16)
Broward County requires final inspection for occupancy, and if your parcel’s unincorporated, we sometimes see a second fire marshal review that city parcels skip. We handle all re-inspections if items come up. You’ll receive a final walkthrough packet with as-built drawings, manufacturer warranties, and maintenance notes specific to the materials you selected.
The Real Choices You’ll Make on a Junior ADU & Interior Conversion
- Kitchenette scope: Wet bar with microwave and mini-fridge ($3,500-$6,000) versus full cooking kitchenette with range, hood, and dishwasher ($8,000-$15,000). The full kitchenette requires a larger electrical service upgrade and grease-rated venting, but it’s what most homeowners want if they’re renting the unit.
- Bath configuration: Wet bath with curtain or glass panel (space-efficient, $4,000-$7,000) versus full 3-piece bath with separate tub or shower ($7,000-$12,000). In the 900-1,200 square foot original footprints common in Pompano Beach Highlands, the wet bath often wins.
- Separate entrance location: Converting an existing window to code-compliant egress door ($2,500-$5,000 with impact rating) versus cutting new opening in a gable or side wall ($5,000-$10,000). The existing window route is cheaper but depends on your floor plan and foundation.
- Mechanical systems: Extend existing HVAC with zone damper ($3,000-$6,000) versus dedicated mini-split ($2,500-$5,000). Mini-splits are louder but give the tenant independent control, which most landlords prefer.
- Impact-rated openings: Required for any new exterior door in Broward County; upgrade adjacent existing windows at same time for consistent wind-load performance and insurance credit. This adds $4,000-$12,000 but often pays back in premium reduction.

Why Pompano Beach Highlands Homes Make This Job Different
The housing stock here shapes everything about how we build. Pompano Beach Highlands is dominated by single-story CBS homes built from the mid-1950s through 1980 - flat or low-slope roofs, single-car carports, and in many cases, original aluminum wiring that hasn’t been touched in fifty years. These homes predate modern Florida hurricane codes by decades, which means any Junior ADU & Interior Conversion in Pompano Beach Highlands triggers the Florida Building Code’s 25% rule: if your renovation touches more than 25% of the structure in a twelve-month period, the entire home must be brought to current wind-mitigation standards.
We’ve learned to spot the warning signs early. In the Highlands, we regularly see flat-roof scupper blockages cause catastrophic interior water intrusion during single storm events - the 60+ inches of annual rainfall here has nowhere to go on this flat terrain with a high water table. Salt air from roughly a mile east accelerates corrosion of fasteners and flashing, so we spec stainless or hot-dip galvanized connectors where inland contractors might use standard galvanized. And the permitting reality is genuinely unusual: depending on whether your parcel sits in unincorporated Broward or the city, you’re looking at different inspection schedules, different review timelines, sometimes different interpretations of the same code section. We’ve navigated both paths repeatedly. Homeowners in nearby Pompano Beach Highlands parcels don’t face this specific dual-pathway complexity - it’s a local quirk that adds real project-management overhead.
Many owners pairing this work with a Kitchen Design & Layout in Pompano Beach Highlands or Small & Partial Kitchen Remodels in Pompano Beach Highlands find it efficient to coordinate everything under one permit and one contractor relationship. The same applies if you’re considering this as part of a full Home Additions & ADU in Pompano Beach Highlands scope - our Home Additions & ADU crew handles the coordination across trades so you’re not managing separate electricians, plumbers, and inspectors yourself.

Frequently Asked - Junior ADU & Interior Conversion in Pompano Beach Highlands
From permit approval to final inspection, expect 10-16 weeks depending on whether your parcel requires city or county permitting and whether we discover aluminum wiring or slab moisture issues during rough-in. The permit itself typically takes 4-6 weeks in Broward County right now. Call (844) 665-0162 and we can check your specific parcel’s jurisdiction and current review timeline.
Yes, absolutely - this is not a finish-out you can self-permit. You’re adding a kitchen, bath, and separate entrance, which triggers full building, plumbing, electrical, and mechanical permits. In unincorporated Broward County parcels common in parts of the Highlands, you may also need fire marshal review. We handle all submittals and inspections as part of our standard project management.
Sometimes, if your existing bedroom is adjacent to a bath and the kitchen wet wall aligns with your planned kitchenette location. More often in these 1960s-1970s Pompano Beach Highlands homes, we need to relocate at least the drain line and add a vent stack, plus sister joists for mechanical loads. We won’t know until we review your original floor plan and do a slab scan for existing plumbing paths.
The low end of our range, around $45,000, assumes a compact space (under 450 square feet), existing 200-amp electrical service, minimal plumbing relocation, stock cabinetry, LVP flooring, and a wet bath. Every deviation from that baseline - larger space, aluminum wiring, full kitchenette, tile finishes - moves the number up. We itemize everything in our estimate so you see exactly what drives cost.
We warranty our workmanship for one year from final inspection, and all materials carry their manufacturer warranties - typically lifetime on KraftMaid or Wellborn cabinetry, 10-25 years on flooring depending on product line, and full warranty on mechanical equipment. We register all warranties in your name and provide the documentation at closeout. Manufacturer warranty terms vary by brand and product tier, which we discuss during material selection.
