Garage Conversion ADU in Sunrise Manor: Timeline, Cost, and What Changes Your Price
A garage conversion ADU in Sunrise Manor typically runs $30,000-$80,000, takes 8-14 weeks from permit to final inspection, and works best on slab-on-grade homes where the existing footprint can stay intact. For larger projects, see our Home Additions & ADU services. Most Sunrise Manor homeowners we talk to at (855) 951-4361 are converting a 1-car or 2-car detached garage into a rental unit, in-law suite, or home office. Because Sunrise Manor sits in unincorporated Clark County, your permits route through county offices rather than the City of Las Vegas, which changes both timeline and inspection cadence compared to jobs just west of Nellis Boulevard.
How We Convert a Garage to an ADU, Start to Finish
We break every garage conversion ADU in Sunrise Manor into five stages. You know what’s happening, who’s showing up, and what decision sits in front of you before we start the next phase.
Stage 1: Site Evaluation and Feasibility (Days 1-5)
We walk the garage, check the slab condition, and verify what utilities already run to the structure. In Sunrise Manor, this means testing whether your 1950s-1970s slab has cracked from caliche heave or drainage wash, and whether the original electrical panel can handle ADU loads. You’ll decide: full kitchen and bath, or kitchenette and half-bath? This choice drives your plumbing scope and, honestly, about 40% of your final cost. We photograph everything, measure twice, and deliver your written estimate within 48 hours.
Stage 2: Design, Permits, and Utility Planning (Weeks 2-6)
Because Sunrise Manor falls under Clark County Development Services, not City of Las Vegas Planning, we file directly with the county’s unincorporated area desk. They’ve seen hundreds of garage conversion ADUs on aging tract homes, so they know what to flag: egress window sizing, ceiling height minimums, and whether your garage door opening gets infilled with matching block or framed wall. You’ll choose your exterior finish here - stucco to match the house, or a contrasting texture if the HOA allows. County turnaround is typically 3-4 weeks for ADU plans, longer if drainage or structural engineering gets triggered by slab condition.
Stage 3: Demolition, Prep, and Rough Utilities (Weeks 7-9)
We strip the garage door, frame the opening, run new electrical service from your main panel or a sub-panel if the original is full, and rough in plumbing. In Sunrise Manor, we frequently find unpermitted electrical additions from prior decades - aluminum wiring, overloaded circuits, DIY junction boxes behind drywall. We fix what we find and document it. You’ll pick your HVAC approach here: mini-split mounted high on the wall, or tying into your home’s central system if capacity allows. For roofing upgrades during your conversion, ask about Metal Roofing - Sunrise Manor. Mini-splits win on most Sunrise Manor garage conversion ADUs because the existing furnace wasn’t sized for extra square footage.
Stage 4: Insulation, Drywall, and Finish Work (Weeks 10-12)
We insulate to Clark County’s adopted IECC standards - critical in Sunrise Manor, where summer attic temperatures above a flat or low-slope garage roof can hit 140°F without proper thermal barrier. You’ll select flooring: luxury vinyl plank handles the slab’s moisture vapor better than laminate, and tile stays cool underfoot but costs more to install over potential crack-isolation membrane. We hang drywall, install your kitchen or kitchenette, set the bath fixtures, and run trim. This is where Cabinets & Countertops in Sunrise Manor often comes into play if you’re building out a full kitchen for rental income.
Stage 5: Inspections, Punch List, and Final Walkthrough (Weeks 13-14)
Clark County inspects rough electrical, rough plumbing, insulation, and final occupancy. We don’t schedule final until we’ve walked the space with you and every item on your list is resolved. Our 730-Day Done Right Promise starts the day you sign off. If something’s not right, we make it right - no expiration anxiety at 12 months like most contractors offer.
The Spec Choices That Move Your Number
- Kitchen scope: kitchenette vs. full kitchen. A wet bar with mini-fridge and microwave runs $3,500-$6,000. A full kitchen with range, dishwasher, and standard cabinetry pushes $12,000-$22,000. Rental ADUs in Sunrise Manor almost always justify the full kitchen for income potential; family-use suites can go either way.
- Bath configuration: half-bath, three-quarter, or full. Half-bath ($2,500-$4,500) works if the main house bath is accessible. Full bath with tub ($8,000-$14,000) opens rental eligibility to families with small children. Most garage slabs need a sewage ejector pump if the bathroom sits below your home’s sewer line, which adds $1,800-$3,200.
- HVAC: mini-split vs. central tie-in. A single-zone mini-split ($3,500-$5,500) is self-contained and efficient for 400-600 square feet. Extending central ductwork ($4,500-$8,000) only makes sense if your existing unit has spare capacity, which 1970s-era systems in Sunrise Manor rarely do.
- Garage door infill: framed wall with window vs. block match. Framed and stuccoed ($2,000-$3,500) is faster and lets you add an egress window. Infilled concrete block ($3,500-$5,500) matches original 1960s construction but requires more labor and structural tie-in to the existing slab edge.
- Electrical service: sub-panel upgrade vs. full service. Many Sunrise Manor homes still run 100-amp mains. A garage conversion ADU with full kitchen and bath needs 60 amps minimum for the unit. Sub-panel from existing service ($2,500-$4,000) if capacity allows; full 200-amp upgrade ($4,500-$7,500) if not.
What Garage Conversion ADU Costs in Sunrise Manor, NV
Garage conversion ADU projects in Sunrise Manor range from $30,000 to $80,000, with most falling between $45,000 and $65,000 for a 400-550 square foot unit with full kitchen and bath.
| Cost Driver | Low-End Impact | High-End Impact |
|---|---|---|
| Size and existing condition | $30,000-$42,000 | $55,000-$80,000 |
| Plumbing relocation/new sewer ejector | $2,500 (half-bath, easy tie-in) | $8,500+ (full bath, ejector pump, trenching) |
| Electrical panel and service | $2,500 (sub-panel, adequate main) | $7,500 (200-amp upgrade) |
| Material grade (flooring, fixtures, cabinets) | $8,000 (builder-grade package) | $22,000+ (mid-grade with brand selections like Sterling or Grohe) |
| Permit scope and engineering | $1,200 (standard conversion, no structural) | $4,500+ (drainage engineering, caliche excavation, retaining wall) |
Five variables push you toward the high end: slab condition requiring remediation, need for a sewer ejector pump, electrical service upgrade, full kitchen and bath versus kitchenette, and any excavation where caliche sits shallow. Our written estimate breaks out each line item - no bundled mystery numbers. Upfront pricing, no surprises. What’s not included: your HOA approval (if applicable), temporary relocation if you live in the garage during construction, and utility connection fees from NV Energy or the Las Vegas Valley Water District. Those run $800-$2,500 depending on meter separation requirements.
Why Sunrise Manor Homes Make This Job Different
Sunrise Manor isn’t Las Vegas proper, and that distinction matters from day one. Every permit, every inspection, every code interpretation runs through Sunrise Manor‘s Clark County Development Services channel, not the city desk. Contractors who primarily work the Strip corridor or Summerlin often miss this jurisdictional handoff, which adds weeks when plans get rejected for routing to the wrong authority. We’ve filed enough garage conversion ADUs in 89115 to know the county’s plan checkers by name and their typical markup patterns on aging-home submissions.
The housing stock here shapes what we find when we open walls. Most garages sit on the same unreinforced slab poured in the 1960s or 1970s, often with no vapor barrier between concrete and caliche below. We’ve seen slabs crack from seasonal expansion, from drainage sheet-flow off Frenchman Mountain during July monsoons, and from decades of vehicle loading on concrete never designed for it. The fix isn’t always replacement - sometimes it’s a floating subfloor system over epoxy sealant - but you need a crew that recognizes the symptoms before they frame walls on a moving substrate. For exterior protection, consider our Iron Fence in Sunrise Manor options.
Electrical panels are another Sunrise Manor signature. Federal Pacific, Zinsco, or early Square D load centers with no spare breaker slots appear in maybe one of three garages we convert. We don’t patch around them. We specify the upgrade in your estimate and explain why a 60-amp ADU sub-panel won’t safely feed from a 100-amp main that’s already at capacity running your home’s AC through 115°F August afternoons.
Finally, the caliche. That cement-like calcium carbonate layer sits 12-18 inches down across much of 89115. If your garage conversion ADU needs trenching for sewer, water, or gas extension, we budget jackhammer time and haul-off from the start. Contractors from wetter climates who quote based on backhoe digging hit change orders fast here. We don’t.
Homeowners doing a full property update often pair this work with Backsplash, Tile & Flooring in Sunrise Manor to match the new ADU finishes to a refreshed main house kitchen or bath.

Frequently Asked - Garage Conversion ADU in Sunrise Manor
Most garage conversion ADU projects in Sunrise Manor take 10-14 weeks from signed contract to occupancy permit, with 3-5 of those weeks in Clark County plan check and permitting. Call (855) 951-4361 and we’ll review your specific garage’s timeline based on current county queue times.
Yes. Because Sunrise Manor is unincorporated Clark County, you need a Clark County building permit for any garage conversion ADU, plus electrical, plumbing, and mechanical permits. The county also requires proof that your property meets minimum lot size and setback rules for ADUs. We handle every filing as part of our standard process.
Sometimes, but rarely for a legal ADU. Sunrise Manor’s older homes usually need at least electrical panel expansion and new sewer lines to meet code. If your garage already has a utility sink and you’re only building a half-bath, you might avoid major plumbing relocation. We determine this during our free site evaluation - call (855) 951-4361 to schedule.
