AfterFast, Reliable Home Additions & ADU Across Incline Village
Home additions and ADU construction in Incline Village typically run $45,000 to $130,000 for a room addition and $90,000 to $220,000 for a detached ADU, and the single biggest variable is what’s hiding inside your walls. We’re Barrett & Sons Construction, and we’ve been opening up 1960s and 1970s Tahoe chalets long enough to know that a simple addition rarely stays simple once the drywall comes down. Every Incline Village project starts with a written scope, a written allowance sheet, and a plan for the TRPA permitting process before we touch a footing. Call (877) 610-1318 and we’ll walk your property with you, free.
Why Barrett & Sons Construction Is Incline Village’s Preferred Home Additions & ADU Company
Tom Barrett founded this company in 1998, and his sons run the crews. That’s not marketing copy. When you sign with us for a second-story addition off Tahoe Boulevard or a garage conversion near the Championship Golf Course, the person shaking your hand is the same person who answers when you call with a question three weeks in. Incline Village homeowners have told us the same story for years: a contractor quotes one number, demolition starts, and suddenly there’s a surprise invoice. We don’t work that way. Every scope, every allowance, every price change arrives as a written change order before work proceeds. No exceptions.
We know the dual-jurisdiction dance with Washoe County and the Tahoe Regional Planning Agency better than most, because we’ve been through it on chalets, ranch homes, and high-end second homes all over the 89450 and 89451 zip codes. If your parcel’s impervious coverage is maxed out, we tell you before you spend a dollar on design. That’s not the easy conversation, but it’s the honest one. Tom publishes his name, his address, and his license number. Look it up before you sign anything, with us or anyone else.
Our Home Additions & ADU Services in Incline Village
ADU Design & Permitting
An ADU in Incline Village isn’t just a building project; it’s a permitting project with two masters. Washoe County wants your plans stamped. TRPA wants to see your impervious coverage math, your BMP erosion-control plan, and a formal coverage-credit calculation before a single footing goes in. We handle the full Home Additions & ADU design and permitting sequence: parcel coverage audit, TRPA submittal, county plan review, and a written timeline so you know when each agency is supposed to respond. If your parcel is already over its coverage allocation because of a decades-old driveway, we’ll tell you in week one, not week twelve.
Garage Conversion ADU
Converting an attached or detached garage on a 1970s ranch home in Incline Village is often the most coverage-friendly path to an ADU, because the footprint already exists. That matters when TRPA coverage credits are scarce and expensive. We’ve converted garages off Lakeshore Boulevard and up near Diamond Peak into full one-bedroom units with kitchens, baths, and separate entrances. The typical garage conversion in Incline Village runs $30,000 to $80,000, and the big variables are wiring age, slab condition, and insulation upgrades for 6,300-foot winters.
New Detached ADU
A new detached ADU in Incline Village starts with coverage verification, not floor plans. TRPA caps impervious coverage per parcel, and many existing lots are already at or over their allowable limit. Before we design anything, we pull the parcel’s coverage history and run the math. If you need to retire coverage elsewhere on the lot or purchase credits, we map out exactly what that means in dollars and weeks. Detached ADU construction in Incline Village runs $90,000 to $220,000, with frost-rated foundations and snow-load engineering baked into every plan.
Junior ADU & Interior Conversion
For Incline Village homeowners working with an existing floor plan, a junior ADU or interior conversion can add a rentable or family-use suite without expanding the building footprint. That’s the key advantage under TRPA rules: no new impervious coverage, no coverage-credit purchase, no months-long coverage review. We’ve converted walkout basements and oversized laundry rooms into self-contained units with their own entry, mini-kitchen, and bath. The scope stays inside your existing walls, which keeps the cost down and the permitting faster.

Trusted Brands We Service in Incline Village
When we frame an addition or finish an ADU in Incline Village, we install materials you can look up. Simonton windows and Ply Gem trim on room additions because they hold up to Sierra UV exposure better than off-brand products. PGT impact-rated windows on second-story additions where snow-load and wind exposure at 6,300 feet punish lesser glass. We don’t put mystery brands in your home and call it premium. If it’s going into an Incline Village wall, it’s a name you can verify.
Common Home Additions & ADU Problems We See in Incline Village Homes
- Aluminum branch wiring from the 1960s and 1970s. Open a wall for an addition and you often find aluminum wiring feeding original panels. Current code won’t let us build new square footage on top of it, which means a full electrical upgrade gets added to the written scope before framing continues.
- Undersized headers and framing that don’t meet current snow-load code. Incline Village gets sustained heavy Sierra snowfall. A 1970s chalet built to old code often needs structural reinforcement before a second story goes on. We flag it at inspection, not after the roof is framed.
- TRPA impervious coverage already maxed out from a decades-old driveway. The parcel looked fine on paper. The ADU footprint was approved in the owner’s mind. Then the coverage audit comes back red, and the job stalls until credits are purchased or permeable pavers are retrofitted elsewhere on the lot. We run this audit before you pay for design work.
- Rotted subfloor and failed waterproofing behind original siding. Tahoe’s freeze-thaw cycles push water into places it shouldn’t go. When we open a wall or lift flooring on a 1970s Incline Village home, rotted subfloor and failed flashing are common finds. Our written allowances cover these latent conditions so the change order isn’t a surprise.

FAQs - Home Additions & ADU in Incline Village
Your project stalls on the coverage issue until you either retire impervious surface elsewhere on your lot or purchase coverage credits from another parcel. We run the coverage audit before design begins, so you know the answer in week one, not after excavation. Call (877) 610-1318 and we’ll pull your parcel’s coverage history free as part of the estimate.
Current Washoe County and TRPA codes require snow-load calculations that didn’t exist when many Incline Village chalets were built. A structural engineer verifies that your existing framing and foundation can carry the weight of a new level under heavy Sierra snowfall. We coordinate the engineer, get the stamped plans, and pull the permit. Call (877) 610-1318 and we’ll walk you through what your specific home needs.
We write an allowance for latent electrical conditions into the contract before demo starts. When we find aluminum or knob-and-tube wiring, the upgrade cost is pulled from that written allowance, and you approve a written change order before we proceed. No surprise invoices at the end. Call (877) 610-1318 for a free estimate that includes realistic allowances for an older Incline Village home.
Yes, and many of our Incline Village clients live in the Bay Area and manage projects remotely. Tom’s sons run the crews on-site most days, and every decision, inspection result, and progress update is communicated in writing. We handle the TRPA submittals, the county inspections, and the BMP compliance while you’re away. Call (877) 610-1318 to discuss remote project management.
You must have erosion and sediment control measures in place on the active construction site throughout the entire season, including winter. Failed BMP compliance can trigger stop-work orders and fines that delay your ADU for months. We install and maintain the required BMPs as part of every Incline Village project. Call (877) 610-1318 and we’ll explain what’s needed on your specific parcel.
