Paradise isn’t a city. It’s an unincorporated Clark County CDP, and that single fact changes everything about how you build here. The Strip’s hotel towers, the Harry Reid International Airport corridor, and the residential streets east of Las Vegas Boulevard all fall under one county building department. Out-of-area contractors stumble on this constantly. They pull a standard building permit and think they’re done. They’re not. We’ve been navigating Clark County Development Services since 2014, and we know the permits, the inspectors, and the unwritten rhythms of getting work approved in Paradise.
Why Groundwork Construction Co. of Las Vegas Is Paradise’s Preferred Home Additions & ADU Company
We’ve built our reputation in Paradise one project at a time - from garage conversions in the 1960s stucco tracts east of the Strip to detached ADUs on tight lots near the airport corridor. Our 730-Day Done Right Promise backs every job in writing. If it’s not done right, we make it right. That’s not a slogan. It’s a guarantee you can hold us to.
Our customers in Paradise call us back. They refer their neighbors. They mention the same things: our crew showed up in uniform, the pricing was upfront with no surprises, and someone actually answered the phone at 10 PM when they had a question about their permit status. Live person, 24/7. No voicemail black holes.
Response time matters here. Paradise’s dense urban fabric means tight lots, alley-loaded properties, and parking constraints that slow down crews who don’t know the area. We do. Most Paradise projects get same-day or next-day site visits, and our project managers coordinate with Clark County inspectors to avoid the scheduling gaps that plague out-of-town contractors.
The local knowledge runs deep. We know which Paradise lots have post-tensioned slabs that need GPR scanning before any penetration. We know the county ROW permit requirements for work near the Strip and airport corridor. We know the pre-dawn concrete windows that beat the 115°F summer afternoons. This isn’t our first Paradise build, and it shows.
Our Home Additions & ADU Services in Paradise
ADU Design & Permitting in Paradise
Every Paradise ADU starts with county permits, not city ones. Clark County Development Services reviews ADU applications against unincorporated zoning codes that differ from Las Vegas and Henderson municipal rules. We handle the full design-permit-build sequence, from site surveys and utility mapping to final occupancy sign-off. Our drawings account for Paradise’s specific setbacks, height restrictions, and parking requirements - the details that get DIY permits rejected or delayed for months.
Garage Conversion ADU
Garage conversions in Paradise run $30,000-$80,000 and represent one of the fastest paths to rental income or multigenerational housing. The 1960s-1980s single-story stucco homes common east of the Strip typically have attached two-car garages with existing slab foundations, but those slabs are almost always post-tensioned. We GPR scan before any plumbing rough-in or wall anchor work. Skip this step and you risk severing tension cables - a structural failure that can cost more than the conversion itself. We’ve seen it happen. We don’t let it happen on our jobs.
New Detached ADU
Detached ADUs in Paradise face unique constraints. Lots near the airport corridor run tight, with narrow side yards and alley access that limits equipment staging and material delivery. We design for these realities - compact footprints, efficient utility runs, and construction phasing that minimizes disruption to your main residence. A new detached ADU in Paradise typically falls in the $90,000-$220,000 range depending on size, finishes, and utility complexity. We recently completed a detached ADU behind a 1960s stucco ranch on a tight lot near the airport corridor, where post-tensioned slab penetrations required a GPR scan before we could run utilities. The county inspector flagged the missing right-of-way permit for the utility trench along the public easement, but our crew had already pulled it - avoiding a costly stop-work order and keeping the project on schedule despite the summer heat.
Junior ADU & Interior Conversion
Junior ADUs - converted interior spaces with separate exterior access - work well in Paradise’s smaller stucco ranches where lot coverage limits full detached units. We handle egress window installation, kitchenette rough-in, and the separate metering that Clark County requires for legal ADU status. These projects typically start around $45,000 and scale with finish selections.
ADU Site Prep & Utilities
Paradise’s caliche-heavy soils and near-universal post-tensioned slabs make site prep a specialized operation. We coordinate GPR scanning, trenching permits, and utility tie-ins with NV Energy and the Las Vegas Valley Water District. Our ADU site prep includes temporary drainage planning for the July-September monsoon window, when sudden storms can dump inches of rain onto sites designed around near-zero annual rainfall. Without proper erosion control, a single afternoon storm can wash out a week’s work.
Room Additions & Second Story Additions
Room additions in Paradise range $45,000-$130,000, with second-story work at the higher end due to structural tie-in requirements. We assess existing foundation capacity, roof load paths, and the structural implications of adding square footage to 1960s-era framing. Every addition ties into existing systems - HVAC, electrical, plumbing - and we size new equipment for Paradise’s extreme heat loads, not moderate-climate standards.

Trusted Brands We Service in Paradise
We specify materials built to survive Paradise’s climate. For ADU roofing, we use GAF and Owens Corning shingles rated for 115°F+ thermal cycling and sudden monsoon wind gusts. Windows come from Andersen and Pella with low-E coatings that block desert solar gain. For ADU kitchenettes, we source KraftMaid cabinetry and Kohler fixtures through our verified dealer network, with local warehouse availability that keeps projects moving. We don’t spec what’s cheapest. We spec what lasts. Built to last, backed in writing.
Common Home Additions & ADU Problems We See in Paradise Homes
- Missing county ROW permits near the Strip or airport corridor. Contractors pull a building permit and assume they’re covered. Clark County requires a separate right-of-way permit for any work touching the public corridor. Inspectors in Paradise flag this constantly. We pull both permits before breaking ground.
- GPR scans skipped on post-tensioned slabs. Paradise’s caliche soils made post-tensioned foundations standard from the 1960s forward. Drill or saw without ground-penetrating radar and you can sever tension cables, compromising the entire slab. We scan every time. It’s non-negotiable.
- Concrete poured in afternoon heat. Summer temperatures on Paradise’s asphalt-heavy corridors exceed 115°F. Pour concrete or frame exterior walls in those conditions and moisture evaporates before cure completes. Surface cracking, reduced strength, callbacks. We work pre-dawn, period.
- Drainage designed for zero rainfall. Paradise averages under five inches annually, so many contractors ignore temporary drainage. Then a July monsoon dumps two inches in forty-five minutes and floods the trench, erodes the site, contaminates the utility run. We plan for the storm that statistically always comes.

FAQs - Home Additions & ADU in Paradise
Yes. Paradise is unincorporated Clark County, so your ADU permit comes from Clark County Development Services, not Las Vegas or Henderson. The application, review, and inspection process follows county-specific zoning and building codes. We file these permits weekly and know the submittal requirements cold. Call (855) 951-4361 and we’ll walk you through your specific property’s permit path - estimates are free.
Paradise’s expansive caliche soils made post-tensioned concrete slabs the standard foundation type from the 1960s forward. A ground-penetrating radar scan locates tension cables before any drilling, sawing, or anchoring. Sever a cable and you compromise the structural integrity of the entire slab - a repair that can exceed your ADU budget. We include GPR scanning in our site prep scope for every Paradise project. No exceptions.
Extreme heat forces our concrete pours and exterior structural work into pre-dawn windows, typically 4:00-9:00 AM. Pour after 10:00 AM in July and surface moisture evaporates too fast, causing cracks and reduced compressive strength. We schedule around this reality. It adds coordination complexity, but it protects your investment. Our project managers build Paradise summer schedules with heat contingencies built in.
A right-of-way (ROW) permit from Clark County is required for any construction activity touching public property - utility trenches, sidewalk crossings, equipment staging on county easements. In Paradise, this applies to most work near the Strip corridor and airport-adjacent neighborhoods where public easements run along property lines. It’s a separate permit from your building permit, and missing it triggers stop-work orders. We pull ROW permits as standard practice on every Paradise job that needs them.
Yes, within Clark County setback and coverage limits. Paradise lots near the airport corridor often run 5,000-7,000 square feet with narrow side yards. We design compact detached ADUs - typically 400-600 square feet - that maximize usable space while meeting county minimums for rear and side setbacks, parking, and utility access. We’ve built several in these tight configurations. Call (855) 951-4361 and we’ll assess your specific lot’s buildable area during a free site visit.
