AfterFast, Reliable Home Additions & ADU Across Paradise
A home addition or ADU in Paradise, NV typically runs $45,000 to $130,000 for a standard room addition, and $90,000 to $220,000 for a detached ADU. Those numbers reflect Clark County permitting, FAA airspace review when you’re under the Harry Reid flight path, and the caliche hardpan we hit during excavation. We’re Barrett & Sons Construction, and we’ve been building additions and ADUs in Paradise long enough to know what opens up when you open up a 1970s stucco tract home. If you’re planning a second-story addition, a garage conversion, or a detached ADU, call Tom Barrett at (877) 610-1318 for a free estimate.
Why Barrett & Sons Construction Is Paradise’s Preferred Home Additions & ADU Company
Paradise is unincorporated Clark County. That one fact trips up more out-of-state contractors than anything else we see. They pull a City of Las Vegas permit, start framing, and the job stops dead until the Clark County Building Department re-reviews the scope. We’ve been doing Home Additions & ADU work in Paradise long enough to know exactly which jurisdiction governs your lot, and we file the right paperwork the first time.
Tom Barrett and his sons are on-site most days. That’s not a sales pitch. It’s how we’ve operated since 1998. When you call about your Paradise project, you talk to someone who can answer questions about your specific street, your specific slab, and what the inspector is going to look for. We don’t dispatch strangers from an out-of-state call center. Our crew members carry the Barrett & Sons name, they’re background-checked, and they show up in uniform. If something isn’t done right, the 90-Day Done Right Promise is on the contract: one call brings Tom back to make it right.
Our Home Additions & ADU Services in Paradise
ADU Design & Permitting
Most Paradise homeowners have no idea what Clark County requires for an ADU until they’re standing in front of a stop-work order. We handle the entire design and permitting path, including the FAA Form 7460-1 filing when your ADU penetrates the airspace surface near Harry Reid International Airport. We’ll draw the plans, submit them to Clark County, coordinate the inspections, and hand you a signed-off permit before the first wall goes up.
Garage Conversion ADU
Converting an attached garage into an ADU in Paradise runs $30,000 to $80,000. The price depends on whether your 1980s tract home still has the original post-tension slab, whether we need to add a kitchenette and full bath, and how much of the existing framing needs to be brought to current code. Slab cutting on post-tension foundations requires specialized knowledge. We’ve done enough of these in Paradise to know what’s underneath before we cut.
New Detached ADU
A new detached ADU in Paradise runs $90,000 to $220,000. The big variable is excavation. The caliche hardpan under much of the Las Vegas Valley sits at unpredictable depths lot to lot, and hitting a thick layer mid-day in 112°F heat stalls foundation work and burns your allowance. We budget for it, we write it into the contract, and we tell you what we found before we pour.
Junior ADU & Interior Conversion
A junior ADU, which is a smaller conversion inside your existing home footprint, often works well in Paradise’s 1970s through 1990s tract homes. It lets you add a rentable unit or in-law suite without triggering the same site-prep costs as a detached build. We’ll walk you through Clark County’s requirements for JADUs, including the separate entrance rules, and we’ll make sure the inspector signs off without surprises.

Trusted Brands We Service in Paradise
When the project calls for windows on an ADU or a second-story addition, we install names you can look up: Simonton, PGT, and Ply Gem. These aren’t mystery brands off a van. Our Paradise customers can verify the materials in their home addition the same way they can verify Tom Barrett’s license number. We keep local stock ready for Paradise jobs, which means fewer delays when you’re already waiting on Clark County review and FAA airspace clearance.
Common Home Additions & ADU Problems We See in Paradise Homes
- Wrong jurisdiction permits. Contractors assume City of Las Vegas rules apply. They don’t. Paradise is unincorporated Clark County, and using the wrong jurisdiction voids the permit and stops the job until Clark County Building Department re-reviews the entire scope. This can set you back weeks.
- FAA airspace violations. Any crane, scaffolding, or structure that penetrates the airspace surface near Harry Reid International Airport needs FAA Form 7460-1 filed before work starts. File it late and you may have to lower the roofline. That’s a redesign, not a delay.
- Caliche hardpan during excavation. The caliche layer under Paradise is inconsistent. One lot it’s three feet down, the next it’s six inches. An excavator that hits thick caliche in summer heat stalls foundation work. If the allowance doesn’t account for it, you’re paying out of pocket before concrete is poured.
- Opened-wall surprises on older homes. Paradise’s 1970s through 1990s stock regularly turns up corroded wiring, undersized non-load-bearing framing, and failed flashing once we open a wall for a second-story addition or ADU connection. These are code triggers, not cosmetic issues. We price them as written change orders before any new work starts.
Pricing for Home Additions & ADU in Paradise, NV
Here’s the honest math for Paradise. A standard room addition runs $45,000 to $130,000. A new detached ADU runs $90,000 to $220,000. A garage conversion ADU runs $30,000 to $80,000. What moves those numbers in Paradise specifically is the Clark County permit path, the FAA airspace review if you’re in 89119 near the airport, and what we find when we open your walls.

FAQs - Home Additions & ADU in Paradise
Yes, you need a Clark County Building Department permit for any garage conversion ADU in Paradise, and the inspection triggers include electrical upgrades, plumbing for a new bath or kitchenette, structural changes to load-bearing walls, and any slab cutting on post-tension foundations. Paradise is unincorporated Clark County, so City of Las Vegas permits do not apply, and using the wrong jurisdiction voids the permit. Call (877) 610-1318 and we’ll pull the right permit before any work starts.
In most cases, yes, but you’ll likely need FAA Form 7460-1 filed before any crane or vertical framing starts, and the review may limit your roofline height. Late filing can force a redesign. We file the form as part of our ADU Design & Permitting work in Paradise, and we’ll tell you exactly what the airspace review adds to your timeline and price before you sign anything. Call (877) 610-1318 to talk through your specific lot.
We inspect first, then we write the allowance into the contract, and when we find something like corroded copper wiring or failed waterproofing, you get a written change order with the price before we touch it. On a 1980s stucco tract home near the airport, our crew opened a wall for a second-story addition and found corroded wiring, undersized non-load-bearing 2×4 framing, and rotted subfloor from failed roof flashing. We rewired to code, reframed with engineered lumber, and priced the waterproofing repair in writing before any new work started. Call (877) 610-1318 for an estimate that plans for what’s behind the drywall.
The caliche hardpan under Paradise varies lot to lot more than people expect, and summer temps hitting 112°F mean concrete needs high-heat mix designs with retarding admixtures to keep it from setting too fast. We budget for caliche when we price your ADU site prep in Paradise, and we tell you what the excavator actually hit before we pour. Call (877) 610-1318 for a foundation estimate that doesn’t burn your allowance on surprises.
We handle both the Clark County Building Department permit and the FAA Form 7460-1 filing as part of our ADU Design & Permitting service in Paradise. You don’t need a separate expeditor, and you shouldn’t pay for one when your contractor should be filing the paperwork themselves. Call (877) 610-1318 and we’ll walk you through the exact filing sequence for your address in 89119.
