Junior ADU & Interior Conversion in Broadview Park: What It Costs and How Long It Takes
Our Home Additions & ADU in Broadview Park turns an existing bedroom, den, or attached living space into a self-contained unit with its own kitchenette, bathroom, and separate entrance, typically running $45,000-$130,000 and taking 10-16 weeks from permit to final walkthrough. Because the work stays inside the existing footprint, it’s faster and less disruptive than building detached, though Broadview Park’s older CBS homes often surface electrical, plumbing, and wind-mitigation surprises once walls open up. Call (844) 665-0162 and we’ll walk your specific space and give you a written estimate with no obligation.
How we handle a Junior ADU & Interior Conversion from first walkthrough to final inspection
We’ve done enough of these in unincorporated Broward County to know where the process stalls and where it moves. Here’s the actual sequence we follow for Junior ADU & Interior Conversion in Broadview Park, with what you’re deciding at each point.
Stage 1: Feasibility walkthrough and scope lock (Week 1)
We visit your property, measure the existing space, and identify the three things that kill timelines: where the sewer line sits relative to your proposed bathroom, whether the electrical panel has capacity for a second kitchen load, and how we’ll create the separate entrance without compromising the main home’s structure. You’ll decide on unit size, whether the kitchenette is wet-bar minimal or full cooking, and if the bathroom gets a shower or just a water closet. We photograph everything, note any Federal Pacific or Zinsco panels we spot, and deliver a fixed-scope proposal within 48 hours.
Stage 2: Broward County ePlan permitting (Weeks 2-5)
Because Broadview Park is unincorporated, we pull permits through the county’s online ePlan portal, not any city building department. We submit architectural plans, structural calculations for any wall modifications, and the mandatory wind-mitigation documentation that pre-1994 CBS homes require. The county reviews fire separation between the JADU and primary residence, egress window sizing, and electrical load calculations. Homeowner decision point: if you want to accelerate, we can submit for plan review while you finalize material selections, but you can’t pull the permit until all specs are locked.
Stage 3: Demolition, rough mechanicals, and structural prep (Weeks 6-9)
We open walls, run new supply and drain lines to the kitchenette and bath, upgrade the electrical panel or add a subpanel if needed, and frame any new interior partitions. In Broadview Park’s 1950s-1970s ranch homes, this is where we usually find galvanized plumbing, ungrounded circuits, or roof decking too deteriorated to leave alone. We flag these immediately, price the fix, and wait for your go-ahead before proceeding. No surprises on the final bill, we stop and talk.
Stage 4: Insulation, drywall, finishes, and fixture set (Weeks 10-14)
County inspection passes on rough mechanicals, then we close walls, install flooring, cabinets, countertops, and the kitchenette appliance package. This is where material lead times matter. A KraftMaid cabinet order runs 6-8 weeks, so if you haven’t chosen by Stage 2, you’re waiting. We coordinate the separate exterior door installation, often a fiberglass impact-rated unit that satisfies current code for the coastal ridge zone. You’ll do a pre-finish walkthrough to confirm paint colors, hardware, and any tile layout.
Stage 5: Final inspection, punch list, and certificate of occupancy (Weeks 15-16)
Broward County inspects for code compliance, fire separation, egress, and mechanical function. We address any corrections same-day if possible, then hand over keys, warranties, and the documentation you’ll need if you ever rent the unit or sell the property. The whole process, from our first visit to your first tenant, typically spans 10-16 weeks unless permit backlog from a recent hurricane season slows the county’s turnaround.
The choices that shape your Junior ADU & Interior Conversion
Every decision below moves the number and the living experience. We don’t default you to one tier, you pick what fits the unit’s purpose and your budget.
- Kitchenette scope: Wet bar with mini-fridge and microwave ($3,500-$7,000 installed) versus full cooking kitchenette with range, vented hood, and dishwasher ($8,000-$16,000). The wet bar works for short-term rental or family use; the full kitchenette qualifies the unit for long-term lease income and adds resale value.
- Bathroom configuration: Three-quarter bath with shower stall ($4,500-$9,000) versus full bath with tub ($6,500-$12,000). In Broadview Park’s compact ranch layouts, the shower-only option often saves enough floor area to add a closet or expand the living space.
- Cabinetry grade: KraftMaid’s semi-custom line with plywood boxes and soft-close hardware holds up to rental turnover better than big-box particleboard alternatives, at roughly 30% more upfront. Wellborn’s inset-door styles suit owner-occupied or high-end rental scenarios where appearance drives rent premiums.
- Countertop material: Cambria quartz resists staining and needs no sealing, ideal if you’re not living on-site to maintain the unit. Laminate saves $1,500-$2,500 but shows wear within 5-7 years in rental use. We template and install either from our verified fabricator network.
- Separate entrance method: Converting an existing window to a code-compliant egress door ($2,500-$5,000) versus cutting a new opening in the CBS wall ($4,000-$8,000 plus potential lintel engineering). The existing-window route is faster and avoids structural review, but only works if the window location gives logical access.
- Impact-rated exterior door and window: Required for code compliance in Broward County’s wind-borne debris region. Standard-grade impact fiberglass runs $1,200-$2,200 installed; architectural-grade with multi-point locking adds $800-$1,500 but delivers better air sealing and security for a tenant-occupied unit.
What Junior ADU & Interior Conversion costs in Broadview Park, FL
Junior ADU & Interior Conversion in Broadview Park typically falls between $45,000 and $130,000. The table below shows where most projects land based on scope, and what pushes you toward either end.
| Project Tier | Typical Range | What It Includes |
|---|---|---|
| Compact wet-bar kitchenette, 3/4 bath, existing window converted to door, standard finishes | $45,000-$68,000 | Basic cabinetry, laminate or entry-level quartz, fiberglass shower stall, electrical panel upgrade if needed, permit and inspection fees |
| Full kitchenette, full bath, new door opening in CBS wall, mid-grade finishes | $68,000-$95,000 | KraftMaid or equivalent cabinetry, Cambria or Silestone quartz, tiled shower, dedicated HVAC mini-split, upgraded lighting package |
| Expanded footprint into adjacent space, high-end finishes, structural modifications | $95,000-$130,000 | Custom layout reconfiguration, Wellborn or architectural-grade cabinets, premium fixtures, engineered flooring, full electrical and plumbing reroute |
Five variables move you up or down this range. First, existing condition: homes with original 1960s electrical panels, galvanized plumbing, or failing flat roofs need upfront infrastructure work that doesn’t show in the finished space but must happen for code. Second, kitchenette and bath location relative to existing plumbing stacks, every foot of new drain line run adds $800-$1,500 in materials, concrete cutting, and labor. Third, material grade, the jump from laminate to Cambria alone can add $2,000-$4,000 on a compact kitchenette. Fourth, whether we’re converting an existing opening or cutting new structure in CBS block, the latter triggers structural calculations and longer permit review. Fifth, permit scope and timing, if your project hits the county during post-hurricane backlog, we can’t control their queue, but we can prep everything perfectly to avoid re-submission delays.
A written estimate from us includes all labor, materials, permit fees, and inspection scheduling. It does not include your appliance package (refrigerator, range, microwave, washer/dryer if desired), window coverings, or any work outside the defined JADU footprint such as landscaping or main-home repairs discovered after walls open. We flag likely extras during the feasibility walkthrough so you’re not ambushed.
Why Broadview Park’s homes and rules make this job different
Broadview Park sits in unincorporated Broward County, which means no municipal building department to walk permits through by hand. Every Junior ADU & Interior Conversion here routes through the county’s ePlan portal and county inspector pool, a workflow shift that contractors accustomed to Plantation or Lauderhill’s city halls routinely mishandle. We’ve seen out-of-area subs show up with city-stamped plans the county won’t accept, burning two weeks while they reformat for ePlan. Our team knows the county’s specific fire-separation checklist for attached dwelling units and schedules inspections through the county system, not a city counter.
The housing stock shapes the work too. Most homes here are 1950s-1970s concrete block ranches built before Hurricane Andrew rewrote Florida’s building code. That means single-pane jalousie or aluminum windows that must be replaced entirely, not repaired, to satisfy current impact standards. It means electrical panels from Federal Pacific or Zinsco that insurers and inspectors both flag. It means flat or low-slope roofs with original decking that won’t pass once we open the ceiling and the inspector sees what’s above. We price for these probabilities upfront rather than discover them halfway through and change-order you.
The water table sits 12-18 inches below grade during wet season, so any exterior work tied to the JADU, new footer for a separate entrance landing, drainage correction, utility trenching, needs dewatering and compaction that inland Broward contractors don’t always anticipate. And hurricane season creates real permit backlogs, if Andrew or a close cousin has recently passed, county plan review stretches from 3 weeks to 8 or 10. We build that possibility into our timeline conversations from day one.

Frequently asked - Junior ADU & Interior Conversion in Broadview Park
Most projects finish in 10-16 weeks, with 4-5 weeks typically spent in Broward County’s ePlan permit review and inspection scheduling. If the county is backlogged after hurricane activity, add 2-6 weeks. Call (844) 665-0162 and we’ll check current permit turnaround times when we quote your job.
Yes, and because Broadview Park is unincorporated, the permit comes from the Broward County Building Division, not a city office. The county will require plans showing fire separation, egress compliance, electrical load calculations, and wind-mitigation upgrades for pre-1994 homes. We handle the entire submission and inspection coordination as part of our scope.
Only if your existing bedroom or den already sits adjacent to a bathroom and kitchen stack, which is rare in Broadview Park’s ranch layouts. Most conversions require at least partial rerouting of drain lines and a panel upgrade to handle the second kitchen load. During our feasibility walkthrough, we map what’s reusable and what isn’t before you commit.
The low end of our range, around $45,000, works when you choose a wet-bar kitchenette, keep the existing bathroom nearby, convert an existing window to the separate entrance, and avoid structural modifications. Choosing laminate countertops, a fiberglass shower stall, and standard lighting keeps material costs controlled. Call (844) 665-0162 for a walkthrough and we’ll identify which corners are safe to cut and which aren’t.
We warranty our workmanship for one year from final inspection, and all materials carry their manufacturer warranties, KraftMaid cabinetry, Cambria quartz, James Hardie siding if exterior work is involved, each has its own terms we pass through to you. We document every warranty and registration at handover so you’re not hunting paperwork later.
