Custom ADU Builder Near You
Accessory Dwelling Units or "ADUs" are standalone living quarters separate from your main residence. In Clark County, ADUs have been a popular way to gain additional space for a mother-in-law apartment, guest house, or as a vacation rental.
​
Building ADUs in Clark County is allowed, and the specific rules about their design and construction vary depending on whether you're in a city or an unincorporated area. Whatever you have in mind, the Renew Design + Build team is ready to help you create a plan and manage your ADU construction project.
The Renew Approach to ADU Construction
We bring the same luxury home expertise and relationship-focused approach to ADU projects, ensuring these important living spaces enhance your property while serving your family's specific needs.
1
Luxury Standards for Independent Living
Your ADU should complement your main home's quality and aesthetic while providing all the comfort and functionality of independent living. We use premium materials, thoughtful design, and quality construction that ensures your ADU feels like a natural extension of your luxury property rather than an obvious addition.
2
Family-Centered Design
We create custom living spaces designed around your family's specific needs and dynamics. Whether you're housing aging parents who need accessibility features, adult children who want privacy and independence, or creating rental space that attracts quality tenants, every detail is planned to serve your goals.

​Privacy and Integration Balance
Our designs carefully balance the need for independent living with thoughtful property integration. We create privacy for both ADU residents and your main home while ensuring the addition enhances rather than detracts from your property's overall appeal and functionality.
Our Design-Build Process
Our proven process ensures your vision comes to life exactly as you imagined, with clear communication every step of the way.
01
Listening First
We begin by understanding your specific goals for ADU living and how this space can best serve your family's current and future needs. Our discussions explore who will live in the space, what level of independence and privacy is needed, and how the ADU fits into your long-term family and financial planning.
02
Developing Your Vision
We create designs that serve your specific family needs while maintaining the luxury aesthetic and privacy requirements of your property. Our space planning optimizes layouts for comfortable independent living within regulatory size constraints, while architectural design ensures seamless visual integration with your main home's style and materials.
03
Proactive Planning
We handle the complex regulatory approval process while developing construction plans that minimize disruption to your family's daily life. Our permit application process includes navigating local ADU regulations, setback requirements, and approval procedures that vary significantly between jurisdictions.
04
Dedicated Team
Our team builds your ADU with the same attention to quality and detail that defines our luxury home construction, creating independent living space that meets your family's standards. Foundation and structural work ensures long-term stability and proper sound isolation between units.
05
Follow-Through
Final walkthroughs and systems orientation familiarize you with all ADU systems and maintenance requirements, while landscape integration and site restoration ensure your property feels more complete rather than more crowded.

Luxury Home Building FAQs
What ADU regulations apply to our property?
ADU regulations vary significantly by jurisdiction and change frequently. We research current requirements for your specific property including size limitations, setback requirements, parking regulations, and approval processes. Our experience with local building departments ensures we navigate the approval process efficiently while meeting all current standards.
How long do ADU projects typically take?
Most ADU projects take 4-8 months from initial consultation to completion, including design development, permit approval, and construction. Permit approval timelines vary significantly between jurisdictions and can affect overall project duration. We provide detailed timelines during planning that account for local approval processes.
What is the typical investment range for custom ADUs?
Our custom ADUs typically range from $300,000 to $700,000, depending on size, features, accessibility requirements, and finish quality. Factors affecting cost include foundation requirements, utility connections, accessibility features, and regulatory compliance needs. We develop detailed budgets early in the process that account for all project requirements.
Can ADUs include full kitchens and separate utilities?
Yes, most ADUs include complete kitchens and can have separate utility metering for electricity, gas, water, and sewer services. Separate metering simplifies management whether the ADU houses family members or rental tenants and ensures clear boundaries between main home and ADU utility costs.
How do you ensure ADU privacy for both households?
We develop construction plans that minimize disruption to your family's daily routines and privacy. ADU construction typically creates less disruption than main home remodeling since we're building separate structures, and we coordinate construction timing and site access to maintain your family's comfort and security.
Do you work with architects and designers?
As a full-service design-build firm, we provide comprehensive in-house design services for our customers. This approach creates a streamlined experience with a single point of responsibility throughout your home experience. However, we also happily collaborate with external architects and designers as your custom home builder if you've already selected them or have existing plans. Our flexible approach ensures your home benefits from cohesive vision and execution, whether you choose our complete design-build service or bring your own design team.

What types of ADUs are there?
Clark County's ADU development codes define the following types of ADUs: Rural Accessory Dwelling Units (RADUs), Urban Accessory Dwelling Units (ADUs), and Cottages. The distinction between Rural and Urban ADUs is about the zoning of the project. For a building to be considered an ADU, there needs to be a primary home located on the property.
​
Beyond the county definitions, there are multiple styles of ADU that are commonly built in Clark County. Some ADUs exist as remodels or additions, connected to the existing home. Others can be stand-alone buildings with their own dedicated power, water, and other utilities.
Tiny homes, small single-family dwellings of not less than 150 square feet, are permanent structures that provide the core amenities of a home in a small space.
Cottages or guest houses on the other hand may be quite large, so long as they meet the requirements of an ADU.
