AfterFast, Reliable Home Additions & ADU Across Paradise
Home additions and ADU construction in Paradise run $45,000-$130,000 for room additions and $90,000-$220,000 for a new detached ADU, with garage conversions typically landing between $30,000 and $80,000. The job almost always takes longer to permit than to frame here, and that’s the part most contractors get wrong. If you live in the 89119 ZIP, your project runs through the Clark County Building Department, not Las Vegas city inspectors, and any roofline or crane boom that rises into flight paths near Harry Reid International triggers FAA Form 7460-1 before a single footing gets poured. We’ve been doing Home Additions & ADU work in Paradise long enough to know exactly which forms come first and which inspector shows up after. Call (877) 610-1318 to have Tom Barrett walk your lot and tell you the truth about what your project will cost.
Why Barrett & Sons Construction Is Paradise’s Preferred Home Additions & ADU Company
Tom Barrett founded Barrett & Sons Construction in 1998, and he still answers his own phone when you call. His sons run the crews that work across Paradise, and Tom lives close enough to drive over and look at a rough-in before the inspector does. The 90-Day Done Right Promise is written on every contract we sign in Paradise. If something isn’t right, one call brings Tom back to make it so.
We’re not a franchise sending a dispatcher to route a stranger to your house. Every crew member who shows up at a Paradise job carries the Barrett & Sons name and has a background check on file. That matters to people between fifty and seventy who have already been burned once by a national outfit that quoted one number on the phone and handed them a different bill at the door. Around here, that story is common knowledge.
Our reputation in Paradise is built on paperwork as much as framing. Every scope change, every allowance, every allowance that isn’t on paper is a surprise waiting for a date. We write it down, you approve it, then we move. Tom publishes his name, his address, and his license number. Look it up before you sign anything with us or anyone else.
Paradise homeowners call us because we know the difference between a Clark County permit package and a Las Vegas city one. We know which inspectors cover the 89119 ZIP and what they red-tag. We know the caliche hardpan under this valley and how it changes footing excavation costs lot to lot. That knowledge is the difference between a contract price and the price you actually pay.
Our Home Additions & ADU Services in Paradise
ADU Design & Permitting
The design phase is where an ADU in Paradise either succeeds or stalls. We pull Clark County permits, file FAA Form 7460-1 when your roofline or crane boom touches airport airspace surface near Harry Reid International, and sequence inspections the way Clark County wants them sequenced. Nothing about that process matches what a Las Vegas city permit requires, and a contractor who doesn’t know the difference will stop your job cold at the first footing inspection.
Garage Conversion ADU
Converting a garage in Paradise usually means cutting door openings into a post-tension slab foundation from the 1970s or 1980s. You don’t cut post-tension cables without a plan. We locate the tendons first, engineer the opening, and only then make the cut. A garage conversion ADU in Paradise runs $30,000-$80,000, and the foundation work is often the line item that moves.
New Detached ADU
A new detached ADU in Paradise starts with excavation, and excavation here means fighting caliche hardpan that varies unpredictably lot to lot. We budget for it honestly and write the allowance into the contract so you see it before we hit it. Summer heat that regularly reaches 112°F compresses outdoor work into pre-dawn windows and demands high-heat concrete mix designs with retarding admixtures or the slab cures wrong and fails inspection.
Junior ADU & Interior Conversion
Converting an interior space into a Junior ADU inside an older Paradise tract home often uncovers what the original builder left behind: aluminum wiring, notched framing, failed waterproofing. We open the wall, we show you what’s there, and if code requires an upgrade, you get a change order in writing before we touch another stud. The permit inspector works for you, not for me. That’s why I like him.

Trusted Brands We Service in Paradise
We install materials from Simonton and Ply Gem on Paradise additions and ADUs, and we stock common parts locally so a snapped latch or a warped track doesn’t strand your project for a week. When your ADU needs windows, you get a brand you can look up, not a mystery product off a van. PGT impact-rated options are available for homes near the airport flight corridors in 89119 where wind and debris load calculations matter more than they do elsewhere in the valley.
Common Home Additions & ADU Problems We See in Paradise Homes
- Clark County vs. Las Vegas city permit confusion. Paradise is unincorporated Clark County, meaning all construction permitting and inspections run through the Clark County Building Department. A contractor assuming Las Vegas city rules applies the wrong forms, fees, and inspection sequence, and the job stops at the first footing inspection.
- FAA airspace violations near Harry Reid International. The 89119 ZIP sits directly under airport flight paths. Filing FAA Form 7460-1 only after framing is up often means discovering the roof peak or crane boom violates the airspace surface, forcing a redesign weeks into the project.
- Aluminum wiring and notched framing in 1970s-1990s tract homes. Opening a wall to tie in a new roofline routinely reveals original aluminum wiring and studs notched past code for old AC chases. That triggers a rewire and structural reinforcement, and the price changes in writing before work resumes.
- Concrete heat failure in summer pours. Pouring footings or forming walls in midday 112°F heat without retarding admixtures causes a premature set and honeycombed concrete that fails structural inspection. Pre-dawn pours with the right mix design are the only way through a Paradise summer.

FAQs - Home Additions & ADU in Paradise
Yes, if any part of the structure or the crane used to build it penetrates the airspace surface near Harry Reid International, you need FAA Form 7460-1 filed before construction. We determine that during the design phase, not after framing begins. Call (877) 610-1318 and we’ll check your lot’s airspace status before you commit to a design.
Clark County requires different forms, fees, and inspection sequencing than the City of Las Vegas. A garage conversion ADU in Paradise runs through the Clark County Building Department, and a contractor who files Las Vegas paperwork will be stopped at the first footing inspection. We file the correct package every time.
We stop work, show you what we found, and write a change order for a full rewire before another stud is touched. Aluminum wiring in older 89119 tract homes is common, and Clark County code will require the upgrade once the wall is open. The permit inspector signs off on the rough-in before we close it back up.
We locate the post-tension tendons with ground-penetrating radar before we cut, engineer the opening to avoid or tension-adjust the cables, and sequence the work around what’s actually under your slab. Cutting blind through a post-tension slab can snap a cable and release forty thousand pounds of tension. We don’t guess.
Yes. The caliche layer across the Las Vegas Valley adds equipment wear and labor to any footing or utility excavation, and its depth varies lot to lot even within 89119. We budget an allowance for it up front, and if we hit it shallower than expected, you pay less, not more. Call (877) 610-1318 for a lot-specific quote.
