ADU Site Prep & Utilities in Melrose Park: What’s Involved, How Long It Takes, and What You’ll Pay
ADU site prep and utilities in Melrose Park covers everything from clearing and grading your property to installing new electrical, plumbing, and drainage lines that feed a detached or converted accessory dwelling unit. For similar work in nearby areas, see our ADU Site Prep & Utilities service in Broadview Park. Most projects we handle here run 3 to 6 weeks for the prep and utility phase alone, with costs typically falling between $45,000 and $130,000 depending on how much of your existing infrastructure needs rerouting or upgrading. Call us at (844) 665-0162 and we’ll walk your property to give you a written, line-item estimate with no obligation.
How We Handle ADU Site Prep & Utilities From First Shovel to Final Inspection
We’ve learned that homeowners in Melrose Park feel less anxious when they know exactly what’s happening and when they need to make a decision. Here’s how we break it down.
Stage 1: Site survey and utility locate (Days 1-3)
Before anything gets touched, we pull permits through the Broward County Building Division and coordinate private utility locates for water, sewer, gas, and electric. You’ll need to decide during this stage whether you’re keeping the ADU on the existing home’s meter or installing separate ones, because that determines trench depth, conduit size, and whether FPL needs to upgrade your service drop. We mark everything, photograph the existing conditions, and flag any trees or hardscaping that must be protected or removed.
Stage 2: Demolition and rough grading (Days 4-10)
Old sheds, concrete pads, chain link fences, or deteriorating patios come out. We cut and cap any abandoned lines, then grade for positive drainage away from both structures. In Melrose Park, where the water table sits 2-4 feet below grade, this stage often reveals saturated soil that requires dewatering or engineered fill. You’ll choose here between standard crushed concrete base and geo-grid stabilization if the soil is particularly soft.
Stage 3: Trenching and underground utilities (Days 11-20)
This is where the real work happens. We trench for water main extension, sewer lateral, electrical conduit, and any gas line you’re running. Because Melrose Park falls under Florida’s High Velocity Hurricane Zone, all underground electrical must be in rigid PVC or Schedule 80 conduit, not direct-burial cable. You’ll specify pipe material during pre-construction: PVC for cost, copper for longevity, or PEX if you’re running a long water line and want freeze protection (rare here, but relevant for exposed runs). We pressure-test everything before backfill and schedule the Broward County rough inspection.
Stage 4: Pad or foundation prep (Days 21-28)
With utilities stubbed and inspected, we form and pour your ADU foundation, typically a monolithic slab on grade with thickened edge beams. Once this phase wraps, many homeowners move on to Cabinets & Countertops - Melrose Park for their interior build-out. Given the high water table, we specify vapor barriers and proper sub-slab drainage as standard, not upgrades. You’ll decide on stem wall height if you’re in a flood-prone pocket of the neighborhood, and whether you want us to rough in future solar conduit or EV charging while the slab is open.
Stage 5: Final utility connections and site restoration (Days 29-35+)
FPL and Broward County Water and Wastewater make their final connections. We backfill, compact in lifts, and restore your landscaping or hardscaping. If your project is part of a full Home Additions & ADU in Melrose Park build, we coordinate handoff to the framing crew. If you’re doing site prep only, we leave you with marked as-builts and a clean site ready for your next contractor.
The Material and System Choices That Shape Your ADU Site Prep & Utilities
Every decision below affects your final price and how the system performs over 20+ years. We don’t default you to the cheapest option; we explain the trade-off and let you choose.
- Electrical service configuration: Tapping your existing 200-amp panel is cheapest if it has capacity, but many 1950s-1970s Melrose Park homes still carry 100-amp panels that won’t handle an ADU’s load. A service upgrade to 320-amp dual lugs adds $3,500-$6,000 but eliminates the headache of load management. Separate meter? FPL charges roughly $1,800-$3,200 for a new service drop, but it lets you rent the ADU as a true independent unit.
- Water and sewer line material: PVC Schedule 40 is standard and code-compliant for sewer; we specify it unless your line crosses under a driveway, where we switch to ductile iron for crush resistance. For water, copper Type L lasts 50+ years but costs roughly 40% more than PEX-B. PEX is fine for most Melrose Park soils, though we avoid it where rocky trench conditions might abrade the jacket.
- Drainage and storm management: Given the water table and summer deluges, we always specify a French drain or channel drain system tied to your storm sewer connection or a dry well. You can choose basic perforated pipe in gravel, or step up to NDS EZ-Drain with built-in aggregate and fabric wrap for faster install and less excavation. The upgrade pays for itself if your lot has any history of pooling.
- Foundation type for the ADU pad: Monolithic slab is standard and most economical. If you’re building with one of our prefab partners, some units require pier-and-beam or stem-wall foundations that we engineer to match. The Home Additions & ADU crew will confirm spec before we pour, since changing foundation type mid-project is expensive.
- Hardscape restoration after trenching: We quote basic sod and irrigation repair as standard. If your trench line crosses a Belgard or Tremron paver patio, you’ll decide whether we lift and relay the existing material or replace it. Matching 10-year-old pavers is sometimes impossible; we show you samples before we break ground.
What ADU Site Prep & Utilities Costs in Melrose Park, FL
For the complete site prep and utilities package in Melrose Park, expect $45,000 to $130,000. That’s a wide range because the job changes dramatically based on what we’re starting with.
| Cost Driver | Low-End Scenario | High-End Scenario |
|---|---|---|
| Distance from house to ADU pad | 15-20 feet; minimal trenching | 60+ feet; crosses driveway or mature landscaping |
| Existing electrical service | 200-amp panel with spare capacity | 100-amp panel requiring full upgrade |
| Water/sewer connection point | Near property line, shallow tie-in | Deep sewer main, pump station required |
| Soil and drainage conditions | Stable, well-draining | Saturated, requiring dewatering and engineered fill |
| Permit scope and HVHZ compliance | Standard ADU permit, existing openings compliant | Triggering full home re-inspection for impact-rated openings |
Our written estimates itemize each stage separately: survey and permits, demolition, trenching and materials, foundation, utility connections, and restoration. What’s typically not included: FPL service drop fees, Broward County Water connection charges, tree removal permits if protected species are involved, and any required septic system upgrades if you’re not on municipal sewer. We flag these during our first site visit so there are no surprises.
Why Melrose Park Homes Make This Job Different
Melrose Park isn’t incorporated, and that single fact reshapes how we approach every ADU site prep and utilities project here. Instead of walking into a city building department, we file everything through the Broward County Building Division portal and work to their inspection cadence. Crews who normally operate in Oakland Park or Lauderdale Lakes under those municipal offices often stumble on the different forms, fee schedules, and inspector assignments. We’ve done enough work in Melrose Park to know which Broward County inspectors prefer photos submitted ahead of time and which want to walk the trench personally.
The housing stock matters too. Most homes here are concrete block construction from the 1950s through 1970s, slab-on-grade with original flat roofs and electrical panels that predate modern load requirements. When we trench for ADU utilities, we’re often cutting through original concrete walks and patios poured decades before anyone thought about secondary dwelling units. The original sewer laterals are frequently cast iron or Orangeburg pipe that crumbles when disturbed, so we always camera the line before we quote.
Then there’s the High Velocity Hurricane Zone. Any significant construction work that triggers a full permit pulls the entire property into HVHZ compliance review. If your existing windows or garage door aren’t impact-rated, Broward County may require upgrades as a condition of ADU approval. We catch this early by running a preliminary code review before we submit, so you’re not mid-project when an inspector flags a non-compliant opening. The June-October hurricane season also compresses our outdoor work windows; we schedule trenching and foundation pours to avoid the peak storm period when possible, and we stockpile materials that could face supply disruptions.

Frequently Asked - ADU Site Prep & Utilities in Melrose Park
Most projects run 3 to 6 weeks from permit pull to final utility connection, with an additional 1 to 2 weeks if we hit saturated soil or need to upgrade your electrical service. Call (844) 665-0162 and we’ll give you a realistic timeline based on your property’s specific conditions.
Yes, and because Melrose Park is unincorporated, all permits route through the Broward County Building Division, not a city office. We handle the application, HVHZ compliance documentation, and inspection scheduling as part of our service. The permit scope depends on whether your ADU is attached or detached and whether the work triggers full-property code review.
Sometimes, if your existing service panel has spare capacity and your sewer lateral is in a favorable position. More often, the 1950s-1970s homes common in Melrose Park require at least partial upgrades to handle the additional load and flow. We assess this during our first site visit with a load calculation and sewer camera inspection.
The $45,000-$130,000 range assumes full utility rough-ins including water, sewer, gas, and electrical for a complete dwelling unit with kitchen and bath. If you’re only running power to a studio without plumbing, costs drop significantly; if you need a grinder pump for sewer elevation or a 400-amp service upgrade, you’ll be at the higher end. We itemize everything in your written estimate.
We warranty our workmanship on underground utilities, foundations, and drainage systems. Specific material warranties come from the manufacturers: copper pipe carries a 50-year corrosion warranty from the mill, PVC sewer pipe is typically 25 years, and electrical components follow the manufacturer’s terms. We register all warranties in your name and provide documentation at project closeout.
