Our home additions and ADU construction services help homeowners throughout Yakima and the Yakima Valley increase living space while preserving the character and value of their property.
Whether you’re expanding a home on a larger property outside town, creating more room for a growing family, or adding flexible living space for relatives, a well-planned addition can provide the functionality you need without the expense and disruption of relocating.
By carefully designing each project around your existing home, we help create seamless transitions between old and new spaces while improving comfort, usability, and long-term property value.
Home Additions & Room Additions
A well-designed addition should feel like a natural extension of your home rather than an afterthought. Our room additions are designed to blend with your existing architecture while providing the extra space your family needs.
Homeowners choose additions for many different reasons. Some need larger family gathering spaces, while others want additional bedrooms, dedicated home offices, expanded kitchens, or multi-purpose living areas. We build custom home additions tailored to the unique needs of each property and homeowner.
Common projects include:
- Primary suite additions
- Family room additions
- Expanded living spaces
- Home offices
- Guest rooms
- Multi-room expansions
Every project is designed to improve the functionality of the home while maintaining a cohesive appearance throughout the property.
Planning & Designing a Successful Addition
Successful additions begin with thoughtful planning. Before construction starts, we work closely with homeowners to understand how the new space will be used and how it should integrate with the existing structure.
Factors such as layout, rooflines, traffic flow, utility connections, natural lighting, and future needs all play an important role in the design process. Our team helps homeowners evaluate available options while identifying solutions that make the most of their property.
Designing an addition in the Yakima Valley also means planning for our distinct seasonal climate—ensuring proper insulation values for hot summers and freezing winters, and calculating roof snow loads correctly. Furthermore, if your property relies on a local septic system rather than city sewer connection (common on larger lots just outside the Moxee city center), we evaluate your current tank capacity early in the planning stage to ensure it can legally handle the added square footage and plumbing fixtures.
As an experienced home addition contractor, we believe careful planning early in the process helps reduce surprises later while creating a smoother construction experience from start to finish.
Accessory Dwelling Units (ADUs)
An accessory dwelling unit provides homeowners with a flexible way to create independent living space on their property. ADUs have become increasingly popular throughout Washington as families look for creative housing solutions that support changing lifestyles and long-term property goals.
Many homeowners build ADUs to accommodate aging parents, adult children, long-term guests, or potential rental opportunities. Others simply want additional living space that remains separate from the primary residence.
As an experienced ADU builder, we help you navigate Washington’s updated housing regulations alongside Yakima’s specific local municipal codes. Whether you’re looking to build a detached backyard cottage or an attached mother-in-law suite, we ensure your layout maximizes functionality while strictly adhering to local setback requirements, maximum height limits, and lot coverage caps. We handle the entire design process to ensure your unit meets local building codes seamlessly.
Projects may include both attached and detached accessory dwelling units, depending on the layout and requirements of the property.
ADU Construction & Project Management
Building an ADU requires careful coordination between planning, permitting, utilities, design, and construction. Our ADU construction process focuses on keeping projects organized while maintaining clear communication throughout each stage of development.
Every property presents unique considerations. Site conditions, access, utility connections, local requirements, and overall project goals all influence the final design and construction approach.
As a trusted provider of accessory dwelling unit construction, we oversee project coordination from initial planning through final completion. Our team works to keep homeowners informed throughout the process while maintaining quality workmanship and attention to detail.
Whether you’re building a detached backyard unit or incorporating additional living space into an existing structure, we focus on delivering a finished product designed for long-term performance and everyday usability.

FAQ
Do I need a permit for a backyard ADU in Yakima?
Yes. All accessory dwelling units and structural home additions require building permits and plan reviews through the City of Yakima or Yakima County, depending on whether your property sits strictly within city limits or in the surrounding unincorporated area.
What's the difference between a home addition and an ADU?
A home addition expands the existing residence by adding square footage directly to the home. An accessory dwelling unit (ADU) is a separate living space that may include its own kitchen, bathroom, sleeping area, and entrance.
How do utility connections work for detached ADUs in the Yakima Valley?
Detached units typically require routing water, power, and sewer lines from the primary residence. If your property is on a private well or septic system, local health department regulations will dictate whether you can tie into the existing system or if an upgrade is required before construction begins.
Do you help with planning and permitting?
Yes. We assist homeowners throughout the planning process and help coordinate the steps necessary to move projects through design, permitting, and construction.
Will my addition match the existing home?
Our goal is to create additions that integrate naturally with the existing structure. We carefully consider architectural details, rooflines, exterior finishes, and overall design continuity during the planning process.
What types of rooms can be added onto a home?
Common projects include primary suite additions, bedrooms, family rooms, home offices, expanded living areas, guest suites, and multi-room expansions.
