ADU Construction in Reno, NV
Full-scope ADU construction built to hold up in Reno's climate and terrain. From foundation and framing through final finishes, we manage every phase of the build so your accessory dwelling unit is livable, durable, and built to fit your property.
What Is ADU Construction?
ADU construction is the physical building process that follows design and planning — turning approved plans into a finished, livable structure.
This includes site preparation, foundation work, framing, roofing, exterior finishes, and installation of windows and doors. It also covers the systems that make the space livable: plumbing, electrical, and HVAC.
Interior construction follows, covering insulation, drywall, flooring, cabinetry, countertops, and fixtures. The scope and sequence vary depending on whether the project is a detached ADU, an attached addition, or a garage conversion.
Feasibility and construction requirements depend on the specific property, ADU type, and applicable local regulations, which is why every project starts with a site-specific assessment.
Our ADU Construction Services
Site Preparation & Foundation
We handle clearing, excavation, and grading before laying the foundation appropriate to your ADU type and site conditions — slab, crawlspace, or stem wall, depending on the lot.
Framing & Roofing
Structural framing and roof systems are built to handle Reno’s seasonal snow load and temperature swings, using materials and techniques suited to the local climate.
Exterior Finishes, Windows & Doors
Siding, trim, and exterior finishes are installed to match or complement your existing home, along with windows and doors placed for light, privacy, and energy efficiency.
Plumbing, Electrical & HVAC
Core systems are installed and connected to existing utilities or new service lines, sized appropriately for the ADU’s square footage and intended use.
Interior Construction & Finishing
Insulation, drywall, flooring, cabinetry, countertops, paint, and fixtures are completed to bring the space to a move-in-ready condition.
The ADU Construction Process
1. Property Assessment
We evaluate the lot, existing structures, garage condition, access, utilities, terrain, and drainage against your goals for the space.
2. ADU Design & Planning
Floor plan, size, layout, and exterior appearance are finalized before construction begins.
3. Feasibility and Requirements
Requirements vary by property, ADU type, and jurisdiction. We do not assume specific permit requirements — homeowners should verify current regulations with the relevant local authority.
4. Site Preparation
Clearing, excavation, foundation preparation, and grading are completed ahead of construction.
5. Construction
Foundation, framing, roofing, exterior finishes, windows, plumbing, electrical, and HVAC are installed in sequence.
7. Final Inspection and Cleanup
We complete final checks, finishing touches, site cleanup, and a homeowner walkthrough before handoff.

ADU Construction in Reno, NV
Reno sits in the Truckee Meadows, on the eastern slope of the Sierra Nevada, about 22 miles from Lake Tahoe and roughly 26 miles north of Carson City. The city is the county seat of Washoe County and part of Northern Nevada’s high desert region.
At an elevation of about 4,400 feet, Reno has a semi-arid climate with four distinct seasons — hot, dry summers and cold winters that can bring snow, particularly at higher elevations and outlying areas like Galena, Montreux, and Washoe Valley. This affects how ADUs are built, insulated, and roofed.
Reno’s residential neighborhoods range from flat suburban lots to sloped, hillside, and rural-style properties, especially in areas like ArrowCreek, Somersett, and St. James Village. Backyard space, garage configurations, and lot grading vary significantly from one property to the next.
Reno at a Glance
- Location: Washoe County, Northern Nevada, in the Truckee Meadows along the eastern Sierra Nevada
- Population: Approximately 265,000 as of the 2020 U.S. Census, with more recent estimates showing continued growth
- County population: Washoe County recorded a population of roughly 486,000 in the 2020 Census
- Elevation: About 4,400 feet above sea level
- Climate: Semi-arid high desert climate with hot summers, cold winters, and seasonal snowfall
- Housing: Single-family detached homes make up roughly half of Reno’s housing stock, alongside apartments, duplexes, and converted units
- Terrain: Mix of flat valley lots and sloped or hillside properties, particularly in outlying communities
Why Reno Homeowners Build or Remodel ADUs
Many Reno homeowners are working with properties that have unused backyard space, an underused garage, or room for an addition. An ADU can provide extra living space for family, guests, or a home office without moving.
Multigenerational households are common across the Reno area, and an ADU can give aging parents or adult children a private, separate living space while staying close to family. Others use the added space more flexibly — as a guest suite part of the year and a home office the rest.
Some homeowners already have an older ADU or converted space on their property that needs updating rather than replacing. In these cases, remodeling can bring a dated structure up to a livable, modern standard.
ADU Considerations for Reno Properties
Local site conditions play a real role in how an ADU project comes together:
- Lot configuration — flat, sloped, or irregular lots affect design and foundation choices
- Backyard access — determines how equipment and materials reach the build site
- Existing structures — garages and outbuildings may factor into conversion feasibility
- Utilities — proximity to existing water, sewer, and electrical lines affects scope
- Climate exposure — snow load and seasonal temperature swings influence insulation and roofing choices
- Grading and drainage — improper drainage planning can cause long-term issues around the structure
No two properties in the Reno area are identical, which is why we start every project with a site-specific evaluation rather than a generic plan.
How Much Does ADU Construction Cost in Reno?
| ADU Project Type | Typical Cost Range | Factors Affecting Price |
|---|---|---|
| Garage conversion ADU | $60,000 – $130,000 | Existing structure condition, insulation needs, utility upgrades |
| Small detached ADU (under 500 sq ft) | $120,000 – $220,000 | Foundation type, site access, finish level |
| One-bedroom detached ADU (500–750 sq ft) | $180,000 – $320,000 | Square footage, layout complexity, utility connections |
| Larger detached ADU (750+ sq ft) | $250,000 – $450,000+ | Size, design complexity, site conditions |
| ADU remodeling & renovation | $30,000 – $120,000 | Scope of updates, existing condition, systems being replaced |
| Higher-end custom ADU | $400,000+ | Custom finishes, complex site work, premium materials |
These are broad ranges, not fixed quotes. Actual cost depends on square footage, existing structures, foundation type, site preparation, utility connections, materials, interior and exterior finishes, and site access.
Factors That Affect ADU Construction Cost
- ADU size and layout complexity
- Foundation type and excavation needs
- Site preparation and grading
- Framing and roofing materials
- Number of windows and doors
- Plumbing and electrical scope
- HVAC system type
- Kitchen and bathroom finishes
- Flooring, cabinets, and countertops
- Exterior finish materials
- Utility connection distance
- Site access and labor conditions
Reno-Area Factors That Can Affect Cost
- Sloped or uneven lots requiring additional foundation work
- Distance from existing utility connections
- Snow-load-rated roofing requirements
- Limited site access for equipment and materials
- Condition of an existing garage being converted
- Backyard configuration and landscaping obstacles
Not every Reno-area property has the same starting conditions, which is why a site visit is necessary before providing an accurate estimate.
Why Detailed ADU Estimates Matter
A detailed estimate is based on an actual site evaluation, accurate measurements, and your specific material and layout selections — not a generic per-square-foot number. This is what helps avoid unexpected costs once construction is underway.
Detached vs. Attached vs. Garage Conversion Construction
Detached ADU Construction
Detached units are built as standalone structures with their own foundation, roofline, and utility connections run back to the main home. This offers more flexibility in placement but typically involves more site work than an attached build.
Attached ADU Construction
Attached ADUs share a wall or structural connection with the primary residence. Construction has to tie into existing framing and utilities carefully, while maintaining separate access and privacy between the two living spaces.
Garage Conversion Construction
Garage conversions start from an existing structure, so construction often focuses on insulation, flooring, wall finishes, and bringing plumbing and electrical up to livable-space standards, while working within the existing footprint and ceiling height.
Realistic ADU Construction Timelines
| Project Type | Typical Construction Timeline |
|---|---|
| Garage conversion | 6 – 12 weeks |
| Small detached ADU | 3 – 5 months |
| One-bedroom detached ADU | 4 – 7 months |
| Larger custom detached ADU | 6 – 9 months |
| ADU remodeling/renovation | 3 – 8 weeks |
Timelines above reflect active construction and can shift based on design complexity, site conditions, material availability, and weather delays common to Reno’s winter months. Design and planning time is separate from these construction timelines.

Frequently Asked Questions About ADU Construction in Reno
Below are some of the most common questions Our Network get from families about ADU. If you have any other questions contact us!
How much does it cost to build an ADU in Reno?
Most ADU construction in Reno falls between $60,000 for a basic garage conversion and $450,000+ for a large, custom detached unit. A typical one-bedroom detached ADU (500–750 sq ft) runs $180,000–$320,000, depending on foundation type, finishes, and site conditions.
How long does it take to build an ADU?
Garage conversions typically take 6–12 weeks of active construction. A small detached ADU takes 3–5 months, and a larger custom unit can take 6–9 months. These timelines don’t include design and planning time, which happens beforehand.
How large can an ADU be?
ADU size limits depend on your specific property and applicable local regulations, which vary by lot and zoning. Many ADUs built in the Reno area fall between 400 and 1,000 square feet, but homeowners should verify maximum allowable size for their property with the relevant local authority.
Is a garage conversion cheaper than a detached ADU?
Yes, typically. Garage conversions generally cost $60,000–$130,000 because they reuse an existing foundation and structure, compared to $120,000–$450,000+ for a new detached unit that requires a full foundation and framing.
What's the difference between an attached and detached ADU?
An attached ADU shares a wall or structural connection with your main home, while a detached ADU is a fully standalone structure elsewhere on the property. Attached units often cost less due to shared utility access, while detached units offer more privacy and placement flexibility.
Can an ADU have its own kitchen and bathroom?
Yes, most ADUs are built with a full kitchen and bathroom to function as independent living space. This requires dedicated plumbing and electrical connections, which are factored into the construction scope and cost.
Can an existing ADU be remodeled instead of rebuilt?
In many cases, yes. Remodeling an existing ADU typically costs $30,000–$120,000 depending on scope, and is often faster and less disruptive than a full rebuild if the existing structure is sound.
