Fast, Reliable Home Additions & ADU Across Sunrise Manor
A home addition or ADU in Sunrise Manor typically costs $45,000 to $130,000 for a room addition, and $90,000 to $220,000 for a new detached ADU. In the 89115 ZIP, most projects run longer and cost more than homeowners expect because the old CMU block homes and the caliche hardpan underneath them demand a contractor who actually knows this side of the valley. Tom Barrett and his sons have worked through enough Sunrise Manor footings, County permits, and block-wall tie-ins to tell you the straight number before the first shovel goes in the ground. Call (877) 610-1318 and we’ll come look at your property, no charge for the trip inside the county.
Why Barrett & Sons Construction Is Sunrise Manor’s Preferred Home Additions & ADU Company
We’re the owner-operated outfit that still puts the name on the truck. Tom Barrett founded the company in 1998, and his sons run the crews that work in Sunrise Manor today. That means the person who shakes your hand at the estimate is the same person you’ll see on-site most mornings, and the phone number on the contract rings to a live person, not a call center.
Sunrise Manor homeowners have dealt with enough out-of-town contractors who quote one price over the phone and hand over a different bill at the door. Our answer to that is written change orders, every time. If the allowance isn’t on paper, it’s a surprise waiting for a date. We pull permits on every eligible job through the Clark County Building Department, because we know that’s the channel in unincorporated Sunrise Manor, and we don’t skip that step to make a bid look cheaper.
Our Home Additions & ADU team has seen the specific problems that show up in 89115: caliche hardpan that destroys auger bits 16 inches down, flat-roofed block homes that need structural review before any wall comes out, and older additions that were never permitted and have to be reconciled with the County before financing moves. That local knowledge keeps your project from stalling at inspection.
Our Home Additions & ADU Services in Sunrise Manor
ADU Design & Permitting
Sunrise Manor sits in unincorporated Clark County, not the City of Las Vegas. That one distinction trips up contractors constantly, because the codes, inspectors, and permit process all run through the Clark County Building Department. We handle ADU design drawings and the full County permit path, including the site plans and utility tie-ins that Clark County wants to see on accessory dwelling units in 89115.

Garage Conversion ADU
Garage conversions in Sunrise Manor usually run $30,000 to $80,000, and the older the home, the more code work the conversion triggers. Many of these 1960s and 1970s garage slabs are thin, uninsulated, and in some cases already have unpermitted walls or electrical run by a previous owner. We bring the conversion up to current County standards, and we include the paperwork so the finished unit is legal and insurable, not a liability at resale.

New Detached ADU
A new detached ADU in Sunrise Manor typically lands between $90,000 and $220,000. The wide gap is driven by the caliche. If your lot has hardpan 14 inches below grade, the footing excavation and utility trenching take more time and more equipment than a standard bid assumes. We price that in from the start, because we’ve dug enough post holes along Lamb Boulevard and Bonanza Road to know what the soil does east of the I-515.

Junior ADU & Interior Conversion
Interior conversions, attached casitas, and junior ADUs built into existing square footage are often the most budget-friendly path in Sunrise Manor. These projects run lower than a full detached unit and typically don’t require the same site work. We inspect the existing walls, roofline, and foundation before we quote, especially on the 1950s block ranches where informal additions have been stacked on over the decades. If there’s unpermitted work back there, we’ll tell you what the County will require before it becomes your problem at closing.

Trusted Brands We Service in Sunrise Manor
We build with materials you can look up. On hardscapes and patios tied to your addition, we carry Techo-Bloc and Cambridge pavers, plus Oldcastle and Quikrete products for the concrete and block work that dominates Sunrise Manor construction. That matters in 89115 because the existing homes are CMU block and the tie-ins, lintels, and footing mixes need to hold up to hard water and summer heat. We keep our local supplier relationships tight so you’re not waiting on a special order when the project is already a week behind from a caliche trench.
Common Home Additions & ADU Problems We See in Sunrise Manor Homes
- Caliche hardpan stops excavations cold. The calcium carbonate layer sits 12 to 18 inches under most of 89115. Standard auger bits burn out fast, and utility trenches that should take a day can stretch into three. Contractors who don’t know this underbid the footings, then come back asking for more money. We price it correctly the first time.
- Unpermitted additions block sale and financing. A huge share of Sunrise Manor block homes have a carport conversion, enclosed patio, or added bedroom that was never permitted through Clark County. Any licensed addition or remodel has to resolve those first. We’ve walked enough of these to tell you quickly whether the old work can be brought up to code or has to come down.
- Flat and low-pitched roofs complicate second-story work. Many of the 1950s through early 1980s homes here weren’t framed for a second story. Before we quote a vertical addition, we check the wall structure and footer depth. On some lots, a room addition out the back makes more sense than going up.
- Summer heat dictates concrete and stucco scheduling. Sustained 110°F temperatures in the Las Vegas Valley mean our pours and framing happen before dawn or after dusk during peak months. Stucco applied in direct sun flash-dries and cracks. We schedule around the heat because we work here, not from an air-conditioned office two time zones away.

FAQs - Home Additions & ADU in Sunrise Manor
A room addition in Sunrise Manor runs $45,000 to $130,000, and a new detached ADU runs $90,000 to $220,000. Garage conversions typically fall between $30,000 and $80,000.

Yes. Sunrise Manor is unincorporated Clark County, so every permit and inspection runs through the Clark County Building Department, not the City of Las Vegas. We pull the permits, schedule the inspections, and stand behind the paperwork on every eligible job. The permit inspector works for you, not for us, which is exactly why we like that step.
Only if the scope changes, and only after you approve a written change order. We don’t do surprise invoices at the end. That’s the whole point of the way we bid: allowances in writing, scope in writing, changes in writing. Ask anyone on your street, or look up Tom Barrett’s license number yourself before you sign.
Most room additions run 3 to 5 months, and detached ADUs run 5 to 8 months in Sunrise Manor, depending on site work and County inspection timing. Caliche trenching and summer heat scheduling can shift a week or two, but we give you a realistic calendar before we start and update you if the County schedule moves. Call (877) 610-1318 for a timeline tied to your project.
Every job is backed by our written 90-Day Done Right Promise. If something isn’t right, Tom comes back and makes it right, one call. We live twenty minutes from most of 89115, and if there’s a problem, we want to know about it. Meanwhile, our Home Additions & ADU work stands up to the east valley heat and hard water because we build for this climate, not a generic one.
